  • the patient must be at least 3-4 hours during the time of the procedure and be properly treated.
  • bleeding and vascular injuries may occasionally occur, which can lead to complications due to the size of the femoral artery.
  • 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.
  • one arm of the patient is suitably fixed.
  • the access is placed just above the wrist.
  • different armrests have been developed.
  • 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.
  • This 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.
  • 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.
  • armrests 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.
  • a device for supporting and positioning an arm of a patient 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the support is optionally tilted to the pivot plane mounted on the pivot arm.
  • 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.
  • both the height adjustment and the adjustment of the inclination of the support are continuously adjustable relative to the pivot plane.
  • the inclination of the support is adjustable in stages, but the height is infinitely variable.
  • 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.
  • 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.
  • the height and / or inclination of the support can be adjusted independently of the pivoting of the pivot arm.
  • 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.
  • the device further comprises a support, which is attached to the second end portion of the pivot arm and which carries the support.

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 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.
  • 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.
  • the radial access is placed on the left arm.
  • the device is mounted on the left side of the patient on the treatment table, for example by pushing the base body 110 between Advicelagematter 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.
  • 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.
  • 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.
  • the base member 232 may be slid under the mat 210 in a manner similar to the base body 110.
  • fastening means 235 may be provided, to which a half-shell-shaped tray 233 can be releasably attached to the angled wall 232.
  • 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
  • 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.
