ENVIRONMENTAL SEAL FOR FLUID DELIVERY DEVICE
First Claim
Patent Images
1. An environmental seal for a fluid delivery device, comprising:
- a cap comprising;
a carrier portion including a proximal end and a distal end and a channel extending through the carrier from the proximal end to the distal end;
a plug located in the solid carrier portion; and
wherein the cap is formed in a two-shot molding process such that a first shot forms the carrier portion and a second shot forms the plug in the carrier portion and obstructing the channel, wherein the carrier portion is formed from a material having a relatively high durometer and the plug is formed from a material having a relatively low durometer.

Abstract
An environmental seal for a fluid delivery device may include a 2-shot molded cap including a carrier and a low durometer silicone plug. The seal also may include a cap receptacle that applies compressive force to the plug displacing the plug material and forming a seal between the cap, the plug and the cap receptacle. A cannula may be slidably received in the plug and may move freely through the plug without compromising the seal.

19. An environmental seal for a fluid delivery device, comprising:
-
a cap comprising; a solid carrier formed from a material having a relatively high durometer, the solid carrier including a proximal end and a distal end and defining a channel extending from the proximal end to the distal end; and a solid plug formed from a material having a relatively low durometer, the solid plug received in the solid carrier and obstructing the channel; and a cap receptacle configured to mate with the cap, wherein the cap receptacle includes a proximal end and a distal end and defines a channel extending from the proximal end to the distal end of the cap receptacle. - View Dependent Claims (20)

21. A cannula seal comprising:
-
a nozzle cap comprising a carrier and a plug located in a cavity of the carrier; a nozzle boss engaged with the nozzle cap; a nozzle received in the nozzle boss; a proximal cannula passing from a distal end of the nozzle cap through the plug and into the nozzle boss, wherein the plug forms a seal between the nozzle cap, the nozzle, the nozzle boss and the proximal cannula; and a distal cannula secured between the nozzle boss and the nozzle, wherein the distal cannula, the nozzle and the proximal cannula form a continuous fluid pathway that is sealed from the environment. - View Dependent Claims (22, 23, 24, 25)
