Abstract

A flow pathway subassembly ( 264, 278 ) including medicament flow pathway components of a medical device, and a holder ( 270, 280 ) configured for holding the components so that a center of gravity of the subassembly is disposed substantially on a central longitudinal axis of the subassembly.

First claim

1 . A flow pathway subassembly, comprising:
medicament flow pathway components of a medical device; and a holder configured for holding the components so that a center of gravity of the subassembly is disposed substantially on a central longitudinal axis of the subassembly.

2 . The subassembly according to claim 1 , wherein the holder comprises:
a main body; and a balancing feature for adjusting the center of gravity of the subassembly.

3 . The subassembly according to claim 2 , wherein the balancing feature is connectable to the main body.

4 . The subassembly according to claim 1 , wherein the holder holds the components in a substantially fixed position relative to the holder.

5 . The subassembly according to claim 1 , wherein the medicament flow pathway components comprise:
a valve assembly connectable to a syringe barrel; tubing connected at one end thereof to the valve assembly; a port connected to a second end of the tubing; a patient needle connected to the port to form a fluid pathway from the valve assembly through the patient needle; and a needle cover for covering and uncovering the patient needle.

6 . The subassembly according to claim 5 , wherein the holder comprises a feature for looping and securing the tubing.

7 . The subassembly according to claim 5 , wherein the valve assembly comprises:
a valve plate connected to the first end of the tubing; a valve cover movably housing the valve plate; wherein the flow pathway subassembly further comprises a removable locking element to prevent movement of the valve plate relative to the valve cover.

8 . The subassembly according to claim 5 , wherein the needle cover also provides sterility.

9 . A method of assembling a drug delivery device, comprising:
A) assembling a flow path subassembly; B) packaging and sterilizing the flow path subassembly; C) aseptically filling the flow path subassembly; D) inspecting the filled flow path subassembly; and E) assembling the filled flow path subassembly into a device body.

10 . The method according to claim 9 , wherein step A comprises assembling medicament flow pathway components into a holder configured for holding the components so that a center of gravity of the subassembly is disposed substantially on a central longitudinal axis of the subassembly.

11 . The method according to claim 10 , wherein step A further comprises adjusting a balancing feature of the holder to align a center of gravity of the subassembly with a longitudinal axis of the holder.

12 . The method according to claim 11 , wherein step D comprises rotating the subassembly about the holder's longitudinal axis.

13 . The method according to claim 9 , wherein steps C and D are performed at a facility different from a facility at which steps A, B, and C are performed.
