  It is an object of the present invention to provide an improved insertion device that is simple to manufacture and suitable for delivery in a mounted form, or at least more easily mounted. Older people who may have some exercise problems need an insertion device that exists in a pre-mounted form.

  In accordance with the present invention, an injector device is provided for subcutaneously inserting an infusion cannula into a patient's skin. The injector device includes a housing, a back surface and guide means extending in the longitudinal direction, a member slidable in the longitudinal direction within the housing, an insertion needle for insertion into the cavity of the cannula, and a back surface of the housing. A spring disposed between the directionally slidable member, a locking means for maintaining the spring in a compressed state, and a releasing means for disengaging the locking means, the apparatus further comprising a needle It is characterized by comprising a pivoting member capable of turning from a position where the needle can be inserted to a position surrounding the needle.

  The insertion device according to the present invention is easy to handle in a safe manner even before the use, during use and after use, even by users who are not very dexterous. The user can also select an essentially vertical insertion that allows easy adjustment of the depth of penetration of the needle and thereby the depth of insertion of the cannula. This is important when inserting the injection part yourself. Moreover, this injector has a very simple structure that can reduce the manufacturing cost.

  The insertion needle can be releasably attached to a slidable member during insertion, and the cannula is releasably attached to the injection part, or the insertion needle is a separation unit that the user removes after insertion be able to.

  In a preferred embodiment, the pivot member is secured to a slidable member. This makes the unit easier to manufacture, and the pivot member is shorter than if the pivot member is fixed to the housing. When the pivot member is fixed to the slidable member, the position at which the pivot member allows the insertion of the needle is such that the pivot member bends backward when touched by the user. The angle v is preferably approximately 45 ° or more, and preferably v is 90 ° or more so that the pivot member does not hit the user during insertion. The angle v is the angle between the central axis of the injector device parallel to the insertion needle and the pivot member.

  In a preferred embodiment, the insertion device has means for temporarily securing the pivot member essentially perpendicular to the housing, i.e. in a position essentially perpendicular to the skin to be penetrated prior to penetration. To fix. This is particularly appropriate for patients with movement disorders, as it may be difficult to adjust the insertion angle.

  The housing preferably has means for securely grasping the injector device. Examples of such means include, but are not limited to, rims, grooves, recesses, and optionally rough surfaces of material other than the housing itself, but preferably recesses are used.

  Although there may be various possibilities for placing the pivot member in a position where the pivot member surrounds the needle, in the preferred embodiment, the slidable member is in the forward position and the spring is released. The pivot member surrounds the needle when in the state. When using an injector device in connection with the insertion of an infusion set, it is often envisaged that the user moves the insertion needle back into the housing to protect the surroundings from the used insertion needle. The This means that the user must act against the spring force that pushed the needle forward during insertion, and at the same time the user should avoid the used needle when returning the needle to the housing To do. This can be extremely difficult in some cases for users whose hands and fingertips are less dexterous. According to the present invention, since it is not necessary to use a force to rotate the relatively large pivot member, it is extremely easy for the user to fix the insertion needle safely.

  In one embodiment, the insertion needle is broken and secured securely when the pivot member is placed in the final position and surrounds the needle. Thereby, a used insertion device can be safely disposed of with normal waste.

  In one embodiment, the pivot arm is also a locking means and has a tab that functions as a disengaging means.

  In another embodiment, there are separate locking means and disengagement means. The pivot member then preferably further comprises a tab for securing the arm in a position parallel to the axis of the housing until it is required to pivot the pivot member to a position surrounding the needle.

  Preferably, the pivot member surrounds the needle in a first position parallel to the main axis of the injector device and then pivoted to a second position essentially perpendicular to the main axis, and finally the needle It is turned to the position that surrounds.

  In a preferred embodiment, the pivot member is pivoted 180 degrees from a position essentially perpendicular to the main axis to another position surrounding the needle and is fixed in this position essentially perpendicular to the main axis. Optionally, the needle is broken during processing and secured securely in the pivot member.

  In another preferred embodiment, the injection part to be inserted is provided with an adhesive support which is fixed unreleasably to the injection part and which has an adhesive surface, which is provided with a release liner.

  In this embodiment, the pivot member may have a securing means for removably securing a portion of the adhesive support to the pivot member. This configuration ensures that the adhesive support is folded in a proper manner during insertion so that the adhesive support rotates part of the adhesive surface towards the user's skin when the injection part is inserted. become.

  In another preferred embodiment, the release liner of the adhesive support can also have one or more protrusions. The description of the part protruding from the release liner means that this part is not necessarily in contact with the adhesive surface of the adhesive support, and one or more protruding parts are part of the release liner that makes protective contact with the adhesive surface. It extends beyond the part. One of the protruding portions can be releasably secured to the housing for at least partially removing the release liner from the adhesive support during needle insertion. The entire removal of the release liner occurs when the injector device is removed for disposal after needle insertion, and the release liner is removed and disposed with the used injector device while still attached to the injector device.

  In a more preferred embodiment, the release liner includes at least two separating elements, each element having at least one protruding portion. This allows the release liner to be automatically removed during insertion without the release liner colliding with the insertion needle.

  Preferably, the protruding portion of the first element of the release liner is attached to the pivot member during insertion, and the protruding portion of the second part of the release liner is attached to the housing during insertion. This embodiment facilitates the user to remove the release liner during / after insertion, while the adhesive surface of the adhesive support is fully protected prior to insertion.

  In a preferred embodiment of the invention, the pivot member of the injector device further comprises means for temporarily fixing the adhesive support of the injection part. This prevents the adhesive support from being folded in an inappropriate manner during insertion of the injection part.

  The injector device preferably includes means for stopping the slidable member in the most advanced position, preferably in the form of a stop tab.

  In a preferred embodiment, the injector device has a locking tab that secures the pivot member in a position surrounding the needle.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
1-3 show an embodiment of an infusion set. The infusion set includes an infusion part (0B) and a connector (0A). The infusion portion (0B) includes a base portion (2) having a major surface that is essentially parallel to the patient's skin when the infusion set is attached to the patient. The base part (2) comprises a first set of guide means (13), in this case in the form of two stabilizing fins. The base part further comprises two holding devices (4) which in this case extend from the upper surface of the two step-shaped base parts. An adhesive support (1), which is a plaster in this case, is attached to the inner surface of the injection part. A cannula (5) extends from the base (2), passes through the adhesive support (1) and is in fluid communication with the central cavity (3). The cannula (5) is preferably a soft cannula, but can also be made of metal. A cavity (3), optionally covered with a membrane, is adapted to receive a cannula (6) extending from the connector. In the embodiment shown in FIGS. 2-5, the cannula (6) extends from the central part of the connector and is in a retracted position relative to the front face of the central part. In this embodiment, the base part (2) has two notches (12) and forms two flaps to which the holding device (4) is attached. The connector (0A) includes two arms (9) having four carvings (10) adapted to be attached to the holding device (4). The connector (0A) is symmetrical around the major surface and around a plane perpendicular to the major surface and parallel to the major axis, allowing the connector to fit with the base in two ways. The cannula (6) is in fluid communication with a tube (7) that allows connection to a medical device such as an insulin pump. In this embodiment, the central part of the connector has two groove-shaped second sets of guide means (8) arranged symmetrically around the main surface of the connector. In this embodiment, the connector further comprises a recessed gripping means (11). The gripping means 11 is optional and can be selected from the group consisting of a rim, a groove, a recess, or optionally a rough surface of a material separate from the connector itself.

  FIGS. 4 and 5 show another embodiment of the invention, in which the connector has two grooves (14), in this case symmetrically arranged around the main surface of the connector. However, since this groove is not connected to the injection part, it does not have to be arranged symmetrically around the main surface.

  Whether the infusion set is inserted manually or by an injector, the infusion part (0B) and the connector (0A) are supplied to the user as two separate units of sterile packaging. When inserted manually, the injection part (0B) is combined with a needle unit having the same locking means and guide means (8) as the connector at the time of delivery. The needle unit comprises an insertion needle extending from the central front surface, which insertion needle extends through the cannula (5) and beyond the end of the cannula during delivery. The only function of the needle unit is to penetrate the user's skin and when the needle unit is removed and replaced with the connector (0A), the cannula (5) remains under the skin.

  The connector (0A) can be connected to the luer coupling member via the tube (7). A suitable therapeutic substance, such as insulin, can be administered from the pump via the luer junction. The connector can also be a kind of closure with a suitable inlet for the insertion needle of the syringe. In order to reduce trauma to the skin, such a closure can remain in place for up to three days, during which time the user can have a medication such as insulin injected from the entrance.

  Even when the user's hand and fingertip are not very dexterous, it is important for the user that the injection part (0B) and the connector (0A) can be easily replaced, that is, engaged and disengaged. In the injection set of the present invention, the movement used to unlock the injection portion (0B) from the connector (0A) is a simple and easy movement such as pushing the connector between the index finger and the thumb. Meets this purpose. Also, the opposite force from each of the index finger and thumb pushing towards each other is used not only to unlock the device, but also when pulling out the connector from the inlet (0B). In order to disengage the connector (0A) more easily, the arm (9) can be made of a soft and flexible material or, for example, in the groove (14) in the shoulder of the connector (0A). It can be made very flexible by adjusting the hardness of the fixing of the arm (9) to the central part, such as by changing the size.

  The arm (9) is extremely flexible, but when it is positioned on the user's skin, accidentally releasing and withdrawing the connector from the injection site requires the device to be under pressure from both sides simultaneously, The risk is quite small.

  FIGS. 6-11 show a first embodiment of an injector device (29) that can be used for injection of the injection part (0B) of the injection set. In FIG. 6, the injector device is separated from the injector (0B), and FIGS. 7 and 8 show the same injector device (29) coupled to the injector (0B).
