DEVICE FOR STORING AND POSITIONING A PATIENT'S ARMS

AS WELL AS MODULAR ARRANGEMENT

Background of the invention

The present invention relates to a device for positioning and positioning an arm of a patient, in particular for the storage and positioning of an arm for a transradiale Herzkatheteruntersuchung. Furthermore, the present invention relates to a modular arrangement for securing an arm of a patient relative to a treatment table.

For a number of medical examinations, it is necessary to fix limbs of the human body and store suitable. This also applies to a variety of surgical procedures.

For the examination of coronary vessels by means of a cardiac catheter and for the minimally invasive treatment of disorders of the coronary arteries, access via the femoral artery (arteria femoralis) has been proven for many years. Access via the femoral artery also allows large stents and catheters to be inserted, and is particularly preferred for complicated procedures.

However, the patient must be at least 3-4 hours during the time of the procedure and be properly treated. In addition, bleeding and vascular injuries may occasionally occur, which can lead to complications due to the size of the femoral artery.

For these reasons, access via the radial artery has become more important in recent years. The radial artery is in humans the continuation of the brachial artery (arteria brachialis) after the elimination of the ulnar artery (ulnar artery). This access is also called radial access.

In order to properly perform the necessary intervention, one arm of the patient is suitably fixed. The access is placed just above the wrist. In order to make it easier for the attending physician to fix the arm and possibly the hand, different armrests have been developed. For example, in US 2014 0059772 AI a padded armrest is described which has a support for the elbow and the hand of the patient. The hand is fixed to the palm rest by means of a strap.

Another armrest is known from US 4369774 A. This armrest consists essentially of a rigid support, which has a slightly rising from the patient's body forearm rest with it adjoining slightly downwardly inclined palm rest for extending the wrist. Both the forearm and the hand are fixed with ribbons.

Another armrest is known from WO 2014 123729 AI, which is rotatably mounted relative to a support table. Another rotatable armrest is described in US 6 663 055 B2.

In contrast, US 5,263,497 A, US 5,623,951 A, and US 5,845,643 A describe armrests in which the wrist is to be fixed relative to the forearm in an overstretched position to facilitate radial access.

In other armrest described, however, their suitability for X-ray examinations is in the foreground. These armrests are for this purpose of a material permeable to X-rays, the armrests can also have areas that specifically block X-rays to protect other areas of the human body. Examples thereof are described in WO 2015 012906 A1, US Pat. No. 6,101,650 A, US Pat. No. 2014 0316253 A1, US Pat. No. 8,700,131 B2, EP 1 898 858 B1, and US Pat. No. 8,369,933 B2.

Another armrest is offered by the company Adept Medical Ltd, Auckland, New Zealand under the name Starboard a. Information on this can be found at http://www.adeptmedical.co.nz/pages/starboard. This armrest is characterized in particular by the fact that a hand fixation is pivotally mounted relative to a forearm rest, so that the hyperextension of the hand is variably adjustable.

However, it has been shown in daily use that the armrests described above do not allow in all treatment situations comfortable for the patient storage of the arm while ensuring easy access for the doctor. In addition, some of the armrests are relatively expensive and therefore expensive. Brief description of the invention

Against this background, there is a need for a reliable, variable and inexpensive device for positioning an arm, particularly in a transradial examination.

In one embodiment, a device for supporting and positioning an arm of a patient is provided. In this case, the device can have a planar basic body which can be pushed under the back of a lying patient or under a rest mat placed on a treatment table. Furthermore, the device may have a swivel arm with a first end region, which is pivotally mounted on the base body and can be pivoted in a pivot plane relative to the base body. The apparatus may further comprise a recess for receiving an arm of a particular lying on the treatment table patient, which is attached to a second end portion of the pivot arm, wherein a distance of the support of the pivot plane of the pivot arm is changeable.

According to one aspect of the device described here, the distance of the support, on which the patient deposits his arm, can be adjusted by the pivoting plane. This makes it possible for the attending physician to adjust the height of the arm relative to the body and thus to the patient lying. It has been found that in particular a height adjustment of the support is favorable both for the comfort of the patient and for the attending physician. Since patients have different body proportions, the patient's shoulder joint is at a different height relative to the main body. A fixed distance of the support from the body could therefore lead to an uncomfortable posture and cramping of the patient. In contrast, the device described here allows the height of the support, which can also be referred to as a forearm rest, adapted so that the patient can place his arm in a relaxed position for him. This is especially true for very large and very small patients. The relaxed posture and the optimal angle in the shoulder joint makes it possible to carry out even longer-lasting examinations without causing a painful cramping of the arterial arteries.

The pivot plane is typically parallel to the body, ie parallel to its areal extent. The pivot plane is the plane in which the Swing arm moves. The pivot axis is typically perpendicular to the pivot plane and the base body. In particular, the main body can be a planar element, for example a plate, which can be pushed under a patient or under a rest mat placed on a treatment table. The body is typically made of a sufficiently strong and rigid material and is designed to accommodate the stresses encountered during use of the device. Since the swivel arm is fastened with its first end region to the main body and supports the support, the base body and the connection to the swivel arm should be so stable that they can adequately absorb the load of the resting arm of the patient.

The pivot arm is detachably connected to the base body according to one embodiment. This improves cleaning and stowage of the device. In addition, the interchangeability of defective parts is given.

According to one embodiment, the support is optionally tilted to the pivot plane mounted on the pivot arm. This makes it possible that in addition, or alternatively, the inclination of the support can be changed. In one embodiment, both the height adjustment and the adjustment of the inclination of the support can be realized by a common adjusting device. This adjusting device may be, for example, a tensioning device guided in a slot, for example a screwing device. The tiltability makes it possible to stretch the arm in the elbow joint. This makes it easier to put on the cardiac catheters and guide wires. In the course of treatment, however, this attitude can be painful and thus stressful for the patient. Due to the tiltability of the elbow joint can therefore easily bring back into a more comfortable posture of the catheter.

According to one embodiment, both the height adjustment and the adjustment of the inclination of the support are continuously adjustable relative to the pivot plane. However, it is also possible that, for example, the inclination of the support is adjustable in stages, but the height is infinitely variable. Alternatively, the inclination of the support can be varied continuously, but the height adjustment is done in stages. It is also possible that both the inclination of the support and the height adjustment takes place gradually. According to one embodiment, the height adjustment and the inclination of the support can be adjusted and changed independently of each other. A stepless change of both the Height adjustment as well as the inclination allows the attending physician the greatest possible flexibility in the positioning of the arm.

According to one embodiment, the height and / or inclination of the support can be adjusted independently of the pivoting of the pivot arm. For this purpose, different structural elements can be provided. The function of the pivoting is taken over by the swivel joint, which connects the swivel arm with the base body. Separately, the height adjustment and the optional adjustment of the inclination of the support.

According to one embodiment, the device further comprises a support, which is attached to the second end portion of the pivot arm and which carries the support. The support thus establishes a connection between the support and the swivel arm and can simultaneously assume the function of height adjustment and / or tilt adjustment of the support. For example, the support may be a component that extends perpendicularly to the pivoting plane and is, for example, detachably connected to the second end region of the pivoting arm. The support is therefore removable and allows it, that the support together with the support can be removed from the swing arm. This allows the device, for example, better stowed.

According to one embodiment, the support is slidably mounted on the support. The displaceability is given in particular in the longitudinal extension of the support, d. H. perpendicular to the pivoting plane.

According to one embodiment, the support has a slot through which engages a fastener which is connected to the support or is engaged with this. The slot, which is typically in the longitudinal extension of the support, d. H. in the vertical direction, when the device is used as intended, allows the displaceability of the support along the support and thus relative to the pivoting plane. The altitude of the support can thus be adjusted comparatively easy.

The fastener may be, for example, a screw, which is formed by a rigidly attached to the support and through the slot cross threaded bolt and a knob with matching internal thread, which is screwed onto the threaded bolt. The knob allows easy release of the screw and thus a shift of the support along the slot and a change in the inclination of the Edition. The voltage applied to an outer side surface of the support support is clamped in the screwed state between this outer side surface and the knob, so that by frictional displacement or tilting of the support against the support is prevented. To further improve the frictional engagement, the outer side surface of the support and / or the side of the support facing the outer side surface of the support can be roughened or profiled.

The support may be, for example, a substantially flat component. Typically, the support-facing side of the support is planar, at least in the region that comes into contact with the support. The outer side surface of the support, which comes into contact with the support, is likewise typically flat, so that a tilting of the support against the support when the screwed connection is loosened while retaining the planar contact is readily possible. However, the support and / or the support may have one or more stops which limit the tilting movement of the support.

The side facing the knob side of the support can, but need not, be flat. It is also possible that in the slot a sliding block with through hole, which is sufficiently large, so that the threaded bolt can pass, is used. The sliding block can take over, for example, the leadership of the threaded bolt in the slot.

According to one embodiment, the pivot arm on a slot through which engages a fastener which is connected to a lower end of the support or is in engagement therewith. The typically extending in the longitudinal direction of the pivot arm slot allows to change the distance of the support from the pivot point of the pivot arm. The location of the slot typically defines the second end portion of the pivot arm to which the deck is secured.

The displaceability of the attachment point of the support on the pivot arm defines a further degree of freedom for the attending physician to adjust the position and position of the arm, whereby a further improvement in comfort is given.

The support can be attached to the pivot arm about its longitudinal axis optionally also rotatable. As a result, it can also be used to change the rotational position of the support relative to the longitudinal extent of the pivoting arm, which contributes to a further improvement in the positioning of the patient's arm. Since hereby the alignment of the Support against the longitudinal extent of the pivot arm is changeable, the angle of the support can also be adjusted independently of the pivot angle of the pivot arm. This is particularly advantageous if the pivot axis is not in the region of the shoulder joint but offset it.

Alternatively, it is possible that the support is only slidably mounted, but not rotatably mounted on the pivot arm.

According to one embodiment, the support has at its end facing the pivot arm on a base member having a support surface which comes into contact with the pivot arm. The support is in particular detachably connected to the base element with the pivot arm.

In one embodiment, the pivot arm is designed in the form of a flat bar with opposite flat surfaces. It is also possible that only one of the two surfaces is flat, for example, the surface facing the support. The repellent side of the support may also be curved. The slot typically extends in the longitudinal extent of the flat bar and passes through the opposite surfaces, and may for example extend to about the middle of the flat bar in the longitudinal direction.

In the first end region of the swivel arm, for example, a bore may be provided for receiving a screw connection. Alternatively, it is possible that the pivot arm has a rigidly connected threaded bolt which engages through a receiving opening in the base body and is screwed onto a provided with a threaded bolt matching internal knob rotary knob to thereby pivotally attach the pivot arm on the base body.

According to one embodiment, the support on side walls, which emanate from a bottom wall and together with the bottom wall form a recess which is approximately half-shell-shaped, wherein at a front end of the bottom wall a rigidly angled to the bottom wall palm support surface is arranged.

In one embodiment, the support is formed in the form of a half shell. In this case, viewed in cross-section perpendicular to the longitudinal extension of the support, the inside may be round, for example semicircular, formed, the outside, however, rather rectangular. However, it is also possible that the inside has a more rectangular profile. For example, the support may be formed of a sheet material with bent-over edge regions which define the side walls.

In particular, the support facing outer side surface of the support is, as described above, planar, to allow a flat contact with the support and not to affect the tiltability of the support, but at the same time to provide a sufficiently large contact area, so that the support is sufficiently fixed by frictional engagement with the support when the screw is made.

According to one embodiment, the support is connected only on one side with the support. For example, the support contacts the support only on one of its outer side surfaces, so that the support, i. H. its longitudinal axis, laterally offset from the longitudinal axis of the pivot arm extends. Typically, the support is located on the side of the support away from the patient. On this side is then also the knob, which is freely accessible to the doctor. The support can therefore in particular eccentrically to the support, d. H. asymmetrical, be arranged, whereby the height adjustment and / or tiltability improves the support is.

According to one embodiment, the supporting side facing wall of the support is more stable, for example, with a greater material thickness, designed as the other side wall of the support, since the support is connected only at this side wall with the support. The other side wall is free.

According to one embodiment, the support is U-shaped. The legs of the U-shaped support are connected to the side walls of the support. As a result, a symmetrical design is possible. The support is therefore loaded evenly.

The at the front end of the edition, d. H. at the end facing away from the body of the patient (at the end facing away from the pivot joint) of the support, rigidly angled hand rest area allows a defined overstretching of the wrist, so as to facilitate the placement of access for the physician. However, it is not necessary that the wrist be permanently overstretched so that the hand does not have to be permanently overstretched by a band or the like.

The device can be constructed according to an embodiment of individual, releasably interconnected components. For example, supports with different lengths are provided so that the device can be adapted to local conditions. If, for example, a very thick support mat is used or if the planar base body is to be inserted into a receptacle provided laterally in the treatment table, a longer support is desired than with thinner support mats. Likewise, the swivel arm can be replaceable, to allow a quick adjustment here too. In addition, the disassembly of the device in its individual components allows easy repair and cleaning.

According to one embodiment, the device for supporting and positioning a patient's arm is adapted and suitable in particular for carrying out a trans-radial cardiac catheterization.

According to one embodiment, a modular arrangement for securing a patient's arm to a treatment table comprises a device for supporting and positioning a patient's arm, as described above, a table shelf mountable to the treatment table, and an elbow or upper arm support can be attached to the table.

The table shelf serves the treating physician as a storage surface for medical device during treatment.

The elbow or upper arm support is typically attached to the treatment table on the opposite side and serves to support the other arm of the patient.

According to one embodiment, the table shelf is mountable to the treatment table separately from the device for supporting and positioning a patient's arm. As a result, the doctor is free to choose the exact positioning.

According to one embodiment, the device is made of a plastic, for example a thermoset or thermoplastic or a composite material, and in particular made of PVC. Optionally, different plastics can also be used for the individual parts of the device. Since the swivel arm and the swivel joint formed between the base body and the swivel arm are usually mechanically stressed the most, more stable plastics, for example composite materials, can be used for this in comparison to other parts of the device. Alternatively, these parts can also with a correspondingly greater material thickness be provided. It is also possible to make the support of a more stable plastic, for example a composite material. Examples of suitable composite materials are fiber-reinforced plastics and in particular carbon fiber-reinforced composite materials, for example carbon.

The embodiments described above can be combined with each other as desired.

embodiments

Figure 1 shows a perspective view of a device for supporting and positioning an arm of a patent according to one embodiment.

The device has a typically planar and flat main body 110, which has a rectangular, for example, substantially square shape in the embodiment shown here. The base body 110 has, in one of its corner regions, an extension 111 extending in the plane of the main body 110, which may also be referred to as a fixed arm 111 and which forms the fixed part of a joint. The pivotable relative to the main body 110 part of the joint is formed by a pivot arm 120 which is rotatably connected at its first end portion 121 by means of a pivot pin 112 or the like rotatably connected to the fixed arm 111. This hinge forms the swivel joint 116 for the swivel arm.

Alternatively, the fixed arm 111 may also be formed on a longitudinal side of the main body 110.

Typically, the fixed arm 111 is integrally formed with the main body 110. However, it is also possible that the fixed arm 111 is produced as a separate component and is connected to the base body 110, for example, by a material fit.

The main body 110 may alternatively have an example triangular shape, with one of the tips of the triangle is typically opposite the fixed arm 111, so that the main body 110 can be pushed with this tip ahead under the patient.

The pivot arm 120 is typically an elongate and flat member, such as a flat bar. It may, for example, have the same material thickness as the main body 110. Alternatively, the pivot arm 120 may be made thicker. In the embodiment shown here, the pivot arm 120 has a substantially constant cross section. Alternatively, the cross-sectional area may also decrease from its first end portion 121 to its second end portion 122.

In the embodiment shown here, the pivot arm 120 in its first end portion 121 has a through hole into which the pivot pin 112 can be inserted, which further extends through a through hole in the fixed arm 111 of the main body 110. The pivot pin 112 has a head which serves as a stop for the pivot pin 112 and, for example, sits on the upper side of the pivot arm 120 or partially extends into the passage opening of the pivot arm 120 when the passage opening is designed accordingly. Furthermore, the pivot pin 112 has an external thread on which a provided with an internal thread knob 113 can be screwed.

Typically, the pivot arm 120 and the base 110 are connected together in the manner shown in FIG. The pivot arm 120 lies on the fixed arm 111, and the pivot pin 112 is inserted from above through the through holes in the pivot arm 120 and the base body 110. Thus, the knob 113 is located on the freely accessible underside of the device and allows the attending physician a quick release and locking the swing arm 120th

The doctor or the medical staff need only solve the knob 113 to freely interlock the pivot arm 120 relative to the base body 110. Preferably, the knob 113 is formed with a correspondingly large diameter. Optionally, an additional profiling may be provided on the outside of the rotary knob 113. By tightening the knob 113, the pivot arm 120 is locked in the position selected by medical personnel. To improve the riding fit between pivot arm 120 and the fixed arm 111 and the base body 110, the pivot arm 120 and the fixed arm 111 may be roughened on each facing surfaces or have a corresponding profiling.

In its second end region 122, the swivel arm 120 has a slot 123 which extends in the longitudinal direction of the swivel arm 120. This slot 123 serves to adjust the distance of a pivotally mounted on the pivot arm 120 support 130 from the rotational axis of the pivot joint 116.

For this purpose, the support 130 can have, at its end pointing to the swivel arm 120, a stationary bolt with an external thread which engages through the oblong hole 123. From the underside of the pivot arm 120, a further provided with an internal thread knob 132 is screwed onto the bolt and thereby fixes the support 130 on the pivot arm 120. The bolt with external thread is hidden in the embodiment shown here by the knob 132 and therefore not shown. The externally threaded pin and knob 132 together form a fastener 132 for securing the bracket 130 to the pivot arm 120.

The support 130 typically has an elongated shape and extends in the assembled state perpendicular to the pivot arm 120. At its end facing the pivot arm 120, the support 130 has a base 133 with a stop face facing the pivot arm 120 in contact with the top the swing arm 120 occurs. For example, the base member 133 may be formed in a circular shape with a diameter that approximately corresponds to the width of the pivot arm 120. The stop surface is therefore also circular. The externally threaded bolt of the support 130 is formed on the base member 133, for example, centrally to the abutment surface.

According to the embodiment described here, the male-threaded bolt is integrally molded with the base member 133. Alternatively, it is possible to provide the bolt as a separate component and, for example, to screw it into an internal thread of the support 130. Furthermore, it is possible that the male screw is made of a different material than the support 130 and is suitably inserted into the support 130. For example, the bolt can be glued or introduced by injection molding insert method in the material of the support 130.

Extending vertically upwards from the base element 133 is a support arm 134 which, in the embodiment shown here, has a substantially rectangular cross-section perpendicular to its longitudinal extent. The support arm 134 has two opposite side surfaces which are flat and parallel to each other in the embodiment shown here. One of the two side surfaces points to the rest 150 described below.

In the support arm 134 and extending longitudinally to its longitudinal extent a slot 131 is formed, which enforced the two opposite side surfaces. The slot 131 serves to adjust the height of the support 150 relative to the pivot arm 120. In addition, allow the slot 131 and the attachment described below, the support 150 on the support 130 a simple tilting of the support 150th

The support 150 is approximately half-shell-shaped in the embodiment shown here and has an approximately rectangular cross-section, seen perpendicular to the longitudinal extent of the support 150 on. The support 150 includes a bottom wall 151 from which extend approximately at right angles to two side walls 153.

On one of the two side walls 153 of the support, a bolt with external thread is formed, which engages through the longitudinal hole 131 of the support 130 and on which a rotary knob 152 is screwed. The bolt with external thread is covered in Figure 1 by the knob 152. Alternatively, it is possible for the side wall 152 of the support 150, which faces the support 130, to have a through-hole through which a bolt with a head coming from the support 150 is inserted. The bolt with External thread and the knob 152 together form an adjusting device for attaching the support to the support 130th

After loosening the knob 152, both the height of the support 150 and its inclination can be changed. If the support 150 is correctly positioned, the rotary knob 152 is tightened and thus holds the support by means of frictional engagement with the support 130.

To improve the friction between the outside of the support-facing side wall 152 of the support 150 and the support 150 facing side of the support 130 and the support arm 134, the facing surfaces may be roughened or provided with a suitable profiling.

The knobs 113, 132 and 152, the pivot pin 112, and the support arm 134 may be made of hard PVC, for example.

The slot 131 of the support 130 and the slot 123 of the pivot arm 120 have a clear length, which is typically at least three times as large as the inside diameter of the respective slot. According to one embodiment, the length of the respective slots is at least five times as large as the clear width, preferably at least seven times as large.

The elongated holes 131 and 123 may have the same width and length. However, it is also possible that the elongated holes 131 and 123 have the same width but a different length. For example, the slot 123 of the pivot arm 120 may be longer than the slot 131 of the support 130.

As can be seen in FIG. 1, all rotary knobs 113, 132 and 152 are preferably of the same size and have a profiling on their outer side. Furthermore, it is possible that all the pivot pins are equipped with the same external thread, so that the knobs can also be formed with the same internal thread. As a result, the manufacturing costs can be reduced and the interchangeability of parts can be simplified.

For storage and temporary fixation of the hand of the patient, a hand rest 154 is formed at one end of the support 150, which is typically integral with the support 150 and forms a continuous surface with the bottom wall 151. The Wrist rest 154 is slightly bent down in an area, so that the hand of a patient can easily be overstretched. In addition, a fastening band can be provided with which the patient's hand is fixed in the overstretched position on the bent region of the palm rest 154.

The hand rest 154 may be made narrower in comparison to the bottom wall 151, so that the hand rest 154 does not restrict the freedom of movement for the doctor and access to the hand.

According to one embodiment, the base 110, the pivot arm 120, the support 130 and the support 150 are made of an unbreakable plastic, which may be, for example, a thermoplastic. In particular, the fixed arm 111 and the pivot arm 120 should be made sufficiently stable to absorb the loads that occur. In this case, 116 can act in particular on the formed between the pivot arm 120 and the fixed arm 111 of the base body 110 pivot joint 116 large moments. It can therefore be provided according to an embodiment that the pivot arm and / or the fixed arm 111 and the base 110 is made entirely of a particularly break-resistant plastic material.

Figures 2A to 2C show the device of Figure 1 from different directions.

FIG. 2A shows a side view from which, in particular, the tiltability of the support 150 relative to the planes defined by the base body 110 and the pivot arm 120 can be recognized. Typically, the overlay 150 can be tilted arbitrarily with respect to this plane. However, it is also possible that the tilting to a maximum angle is limited by suitable stops or the like. The tilting can be uniformly restricted symmetrically for both tilt directions. However, it is also possible that tilting to lower the hand rest 154, i. for moving the hand rest 154 in the direction of the pivot arm 120, is more limited than tilting for lifting the wrist rest 154. Thus, for example, an accidental excessive overstretching of the arm can be avoided.

Furthermore, it can also be seen from FIG. 2A how the height of the support 150 can be changed by displacement along the elongated hole 130 formed in the support arm 134. The length of the slot 131 defines the maximum displacement. Figure 2B also shows a side view from which the configuration of the support arm 134 with the opposite parallel side surfaces can be seen. The support 150 facing side surface of the support arm 134 is in area with the support arm 131 facing outside of the side wall 152 of the support 150 in contact. As a result, a free tilting and a displacement of the support 150 on the support arm 131 after loosening the knob 152 is easily possible.

On the other hand, it can be seen in particular from FIG. 2C how the pivot arm 120 is pivoted relative to the base body 110. In this case, the pivot arm 120 can be pivoted virtually arbitrarily. The pivoting movement is limited only by the knob 132 when it abuts an outer edge of the base body 110.

It can further be seen in FIG. 2C that the support 150 is not arranged centrally above the pivot arm 120 but laterally offset relative thereto. Since the support 150 can also be rotated relative to the pivot arm 120, the support 150 can also be positioned so that its fictitious center axis extends through the fictitious pivot axis of the pivot joint 116 formed between the pivot arm 120 and the base body 110. Basically, the acceptability of the support 150 relative to the pivot axis 120 provides a further degree of freedom for the attending physician to adjust the position of the patient's arm appropriately.

Figures 3A to 3D show a modular arrangement comprising a device for fixing and positioning a patient's arm during a treatment, a treatment table and an elbow support 250. The device may be that shown in Figures 1 and 2A to 2C Act device. For example, the base body 110 can be pushed under a support mat 210, which lies on a treatment table, not shown here. The patient 220 lies on the support mat 210. As can be seen in FIGS. 3A to 3D, the patient's right forearm rests in the support 150. The support 150 can easily reach the base body 110 and thus the support surface on which the patient 220 lies tilted upward in order to allow a comfortable for the patient 220 attitude.

Typically, the radial access is placed on the left arm. For this purpose, the device is mounted on the left side of the patient on the treatment table, for example by pushing the base body 110 between Auflagematter 210 and the surface of the treatment table. After the access has been laid, the left will be on the right side led the patient, as can be seen in Figures 3A to 4D. To facilitate this positioning and stabilize the left arm is the elbow support 250, which is then mounted to the treatment table. The device with the armrest can either be completely removed, or mounted on the right side of the patient at the treatment table.

Furthermore, in Figures 3A to 3D, a table shelf 230 can be seen, which is mounted separately from the apparatus for the armrest to the treatment table. This table shelf 230 is shown in more detail in FIG.

The table shelf 230 may for example be constructed of two separate and separate parts. The first part is formed in the present embodiment by a base member 233 in the form of a flat part. From this base member 233, a support member 231 extends approximately at right angles to the base member 233. The base member 232 and the support member 231 may be formed of an angled sheet metal or an angled plastic part. For example, the base member 232 may be slid under the mat 210 in a manner similar to the base body 110. On the support member 231 fastening means 235 may be provided, to which a half-shell-shaped tray 233 can be releasably attached to the angled wall 232.

In the embodiment shown here, the half-shell-shaped tray 233 is formed by a bottom wall 237 and perpendicular to this upstanding side walls 234. The tray 233 may have a similar shape as the support 150 with the difference that no additional hand rest is provided. The tray 233 may be formed longer than the support 150th

On one of the two side walls 234 slots or slots 236 may be formed, which may extend in a direction approximately perpendicular to the bottom wall 237. These slots or slots 236 may have a greater clearance at their end facing the bottom wall 237 than at their end facing away from the bottom wall 237. The elongated holes 236 are formed so that the head of pins (fasteners) 235 fixed to the support member 231 can pass through the portion of the elongated holes 236 having a larger clearance. If now the tray 233 is lowered, the pins 235 reach the area of the elongated holes 236, which has a smaller inside width. As a result, this area of the elongated holes 236 engages behind the heads of the pins 235. The tray 233 is thus fixed to the support member 131. By lifting the tray 233 it can be easily removed from the support member 231.

The table shelf thus allows the attending physician to store medical device in the immediate vicinity of the fixed arm and to keep it ready for the treatment.

The elbow support 250 recognizable in FIGS. 3A to 3D serves to keep the arm, in which a radial access has already been laid, in a position that is comfortable for the patient. Moreover, it is preferred by many treating physicians if they stand and treat to the right of the patient. For this purpose, the left hand of the patient is guided over his middle of the body to the right side and held by the elbow support 250 in this.

While specific embodiments have been illustrated and described herein, it is within the scope of the present invention to properly modify the illustrated embodiments without departing from the scope of the present invention. The following claims are a first, non-binding attempt to broadly define the invention.
