Syringe with integral safety system
First Claim
1. An injection device, comprising:
- a syringe comprising a proximal end, a distal end, and a plunger extending from the proximal end;
a lug extending radially from the syringe, the lug being disposed proximal from the distal end of the syringe;
a guard slidably attached to the syringe, the guard having a proximal end, a distal end, the guard comprising a slot for receiving the lug therein, whereby the guard may be moved from a first position wherein the distal end of the syringe is exposed to a second position wherein the guard covers the distal end of the syringe; and
cooperating detents on the lug and the guard for retaining the guard in the first position, and in the second position.

Abstract
An injection device for delivery of a therapeutic agent is provided that includes a glass syringe with an integrally molded lug extending radially from the syringe and a guard slidably attached to the syringe. One set of detents on the guard and the lug of the syringe retain the guard in the retracted position. Another set of detents on the guard and the lug of the syringe retain the guard in the extended position. Another injection device for delivery of a therapeutic agent is provided that includes a glass syringe with an integrally molded disk that extends radially from the syringe and a guard slidably coupled to the syringe. One set of detents on the guard and the integrally molded disk of the syringe retain the guard in a retracted position. Another set of detents on the guard and the integrally molded disk retain the guard in an extended position.

13. An injection device, comprising:
-
a glass syringe comprising a body including proximal and distal ends, the body defining a cavity for receiving a medical product therein;
a glass disk integrally molded to the syringe and extending radially outwardly from the distal end of the syringe;
a guard slidably attached to the syringe comprising a distal portion and a proximal portion having a size for sliding along the body of the syringe, the guard being slidable between a first position wherein the distal end of the syringe is exposed and a second position wherein the distal end of the syringe is covered by the guard; and
detents on the guard for selectively engaging the disk for retaining the guard in at least one of the first and second positions. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An injection device, comprising:
-
a glass syringe comprising a body having a proximal end, a distal end, a plunger extending from the proximal end, and a hub on the distal end;
a glass disk integrally molded to the syringe and extending radially outwardly from the hub;
a guard slidably attached to the syringe comprising a distal portion and a proximal portion having a size for sliding along the body of the syringe, the guard being slidable between a first position and a second position;
a first detent on an inner surface of the guard for engaging the disk to retain the guard in the first position; and
a second detent on an inner surface of the guard for engaging the disk to retain the guard in the second position. - View Dependent Claims (22, 23, 24)
