Title:Kits containing medicine injection devices and containers
Abstract: A reloadable medicine injector and methods are described in which a barrel with a receiving cavity is adapted to slidably receive a syringe subassembly for axial movement therein. Upon removal of a safety and release of a syringe driver, the syringe driver moves forward and injects the syringe needle. A plurality of penetration controls are shown for controlling injection needle penetration depth. The penetration controls have an abutment and various lengths to provide different needle penetration depth positions. In one form of penetration control a sleeve is used against which the syringe or related parts contact. In another form the front return spring is used as a penetration control. A cushioning ring may be used to reduce syringe breakage. A load distribution and guide ring may be used to distribute loading applied to the syringe and help guide the moving syringe.

Filing Date:Aug 08, 2005
Application Number:11/199,596
Claims:1. A kit containing a medicine injection device and a container, the kit comprising: the medicine injection device, the medicine injection device having a needle and a sheath over the needle, the medicine injection device also having a sheath remover adjacent the sheath and configured to be grasped by a user to facilitate removal of the sheath, the sheath remover having a front surface adjacent the needle, the front surface being substantially flat; a first container barrel part of the container; a second container barrel part of the container, said first and second container barrel parts forming a barrel cavity when joined together, the barrel cavity being configured for retaining the medicine injection device therein; an interlocking mechanism comprising a first component associated with the first container barrel part, and a second component associated with the second container barrel part; the first and second components interacting with one another to form an engagement by which the first and second container barrel parts may be locked to one another; the first and second container barrel parts being fully locked to one another when the engagement is completely tight; one of the first and second container barrel parts having an insertion end and the other of the first and second container barrel parts having a receiver end within which the insertion end is received; the insertion end having an end surface, and the receiver end having a shoulder provided therein which mates against the end surface of the insertion end when the first and second container barrel parts are fully locked together; a cam-containing spreader, said cam-containing spreader being configured to cause longitudinal separation of the first and second container barrel parts when the first and second container barrel parts are twisted in relative angular relationship; the cam-containing spreader and interlocking mechanism being together configured to enable a twist to transition the container from a condition in which the first and second container barrel parts are fully locked together to a condition in which the first and second container barrel parts are not interlocked, to thereby allow rapid opening of the container and quick access to the medicine injection device; and wherein the container includes an inner shelf having an annular ring thereon, wherein said annular ring is directly against the front surface of the sheath remover when the medicine injection device is retained in the container, and is adapted to act as a shock absorber to alleviate loading of forces on the sheath if the container having the medicine injection device therein is dropped.

2. A kit containing a medicine injection device and a container, the kit comprising: the medicine injection device, the medicine injection device having a needle and a sheath over the needle, the medicine injection device also having a sheath remover adjacent the sheath and configured to be grasped by a user to facilitate removal of the sheath, the sheath remover having a front surface adjacent the needle, the front surface being substantially flat; a first container barrel part of the container; a second container barrel part of the container, said first and second container barrel parts forming a barrel cavity when joined together, the barrel cavity being configured for retaining the medicine injection device therein; an interlocking mechanism comprising a first component associated with the first container barrel part, and a second component associated with the second container barrel part; the first and second components interacting with one another to form an engagement by which the first and second container barrel parts may be locked to one another; the first and second container barrel parts being fully locked to one another when the engagement is completely tight; one of the first and second container barrel parts having an insertion end and the other of the first and second container barrel parts having a receiver end within which the insertion end is received; the insertion end having an end surface, and the receiver end having a shoulder provided therein which mates against the end surface of the insertion end when the first and second container barrel parts are fully locked together; a cam-containing spreader configured to cause longitudinal separation of the first and second container barrel parts when the first and second container barrel parts are twisted in relative angular relationship; the cam-containing spreader and interlocking mechanism being together configured to enable a twist to transition the container from a condition in which the first and second container barrel parts are fully locked together to a condition in which the first and second container barrel parts are not interlocked, to thereby allow rapid opening of the container and quick access to the medicine injection device; and wherein the one of the first and second container barrel parts includes an inner ledge, said inner ledge being directly against the substantially flat front surface of the sheath remover when the medicine injection device is retained in the container.

3. The kit of claim 2 wherein the interlocking mechanism includes a projection on one of the first and second container barrel parts, and a recess on the other of the first and second container barrel parts, with said recess forming a mating engagement with said projection.

4. The kit of claim 3 wherein the projection is on the container barrel part having the insertion end, and wherein the recess is on the container barrel part having the receiver end.

5. A kit containing a medicine injection device and a container, the kit comprising: the medicine injection device, the medicine injection device having a needle and a sheath over the needle, the medicine injection device also having a sheath remover adjacent the sheath and configured to be grasped by a user to facilitate removal of the sheath, the medicine injection device having a front region comprising the sheath remover and a portion of the sheath projecting through the sheath remover; a first container barrel part of the container; a second container barrel part of the container, said first and second container barrel parts forming a barrel cavity when joined together, the barrel cavity being configured for retaining the medicine injection device therein; an interlocking mechanism comprising a first component associated with the first container barrel part, and a second component associated with the second container barrel part; the first and second components interacting with one another to form an engagement by which the first and second container barrel parts may be locked to one another; the first and second container barrel parts being fully locked to one another when the engagement is completely tight; one of the first and second container barrel parts having an insertion end and the other of the first and second container barrel parts having a receiver end within which the insertion end is received; the insertion end having an end surface, and the receiver end having a shoulder provided therein which mates against the end surface of the insertion end when the first and second container barrel parts are fully locked together; a cam-containing spreader configured to cause longitudinal separation of the first and second container barrel parts when the first and second container barrel parts are twisted in relative angular relationship; the cam-containing spreader and interlocking mechanism being together configured to enable a twist to transition the container from a condition in which the first and second container barrel parts are fully locked together to a condition in which the first and second container barrel parts are not interlocked, to thereby allow rapid opening of the container and quick access to the medicine injection device; and a shock absorber within the container and directly against the front region of the medicine injection device when the medicine injection device is retained in the container.
