METHOD AND APPARATUS FOR AUTO INJECTION OF A THERAPEUTIC
First Claim
1. A therapeutic dispensing device (100) comprising;
- a handle (10) defining a cavity (11), the handle having a proximal end (44) and a distal end (46);
a channel (38) positioned within the cavity, wherein the distal end of the handle contains a window (13);
a carriage (12) supported by the handle, the carriage configured to slide into the handle through the opening, and at least partially into the channel, the carriage having a proximal end (2) and a distal end (4), the proximal end having a first opening (8) and the distal end having a substantially non flexible engagement surface and a second opening (6) therein;
a syringe assembly (14) supported by the carriage and at least partially positioned in the channel, the syringe assembly comprising a barrel (20) supporting a plunger (16), and a needle (24) for dispensing contents of the barrel; and
a spring means (40) operably biased between the carriage and the handle.

Abstract
Provided, among other things, is a therapeutic dispensing device (100) comprising: a handle (10) with proximal (44) and distal (46) end, defining cavity (11), and containing a window at the distal end (13); a channel (38) positioned within the cavity; a carriage (12) supported by the handle and configured to slide into the handle through the opening, and at least partially into the channel, the carriage having proximal end (2) and distal end (4), the proximal end having a first opening (8) and the distal end having a substantially non flexible engagement surface and a second opening (6); a syringe assembly (14) supported by the carriage and at least partially positioned in the channel, such assembly comprising a barrel (20) supporting plunger (16), and needle (24) for dispensing contents of the barrel; and a spring means (40) operably biased between the carriage and the handle.

13. A method of dispensing a therapeutic into a user body, the method comprising:
-
providing a therapeutic dispensing device comprising a handle (10) defining a cavity, the handle having a proximal end (44) and a distal end (46), a channel (38) positioned within the cavity, wherein the distal end of the cavity contains a window, a carriage (12) supported by the handle, the carriage configured to slide into the handle through the opening, and at least partially into the channel, the carriage having a proximal end and a distal end, the proximal end having a first opening and the distal end having a substantially non flexible engagement surface and a second pierceable opening therein, a syringe assembly (14) supported by the carriage and at least partially positioned in the channel, the syringe assembly comprising a barrel (20) supporting a plunger (16), and a needle for dispensing contents of the barrel, and a spring means (40) operably biased between the carriage and the handle; positioning the distal end of the carriage against a location on the user body; applying a force on the proximal end of the handle thereby causing the plunger to move downward into the barrel, causing the needle of the syringe to pierce through the second opening into the user body and dispensing the therapeutic in to the user body; and releasing the force causing the spring means to bias the carriage such that the carriage projects out of the handle and completely covers the needle.

14. A method of assembling a therapeutic dispensing device, the method comprising:
-
providing a handle (10) defining a cavity, the handle having a proximal end (44) and a distal end (46), the handle comprising a channel (38) positioned within the cavity, wherein the distal end of the cavity contains a window; providing a carriage (12) configured to be supported by the handle, the carriage configured to slide into the handle through the opening, and at least partially into the channel, the carriage having a proximal end and a distal end, the proximal end having a first opening and the distal end having a substantially non flexible engagement surface and a second pierceable opening therein, wherein the carriage is positioned to reside within the channel; positioning a syringe assembly (14) at least partially in the channel, the syringe assembly configured to be supported by the carriage, and the syringe assembly comprising a barrel (20) supporting a plunger (16), and a needle for dispensing contents of the barrel; and providing a spring means (40) to be operably biased between the carriage and the handle.
