Abstract

A fluid connector assembly. The fluid connector assembly includes a tab portion including a slot; a plug portion slidably connected to the tab portion the plug portion comprising a fluid path and a disc, the disc configured to seat within the slot; a catch feature located on a first end of the tab portion and configured to interact with a reservoir; and a latching feature located on a second end of the tab portion, the latching feature configured to interact and lock onto the reservoir, wherein force applied to the plug portion may overcome a threshold force and unseat the disc from the slot wherein the plug portion moves with respect to the tab portion.

Claims

1. A fluid connector assembly comprising:

a tab portion comprising a disc slot;

a plug portion slidably coupled to the tab portion comprising a fluid path and a disc having a thickness, the disc configured to seat within the disc slot, the disc slot configured to present an interference to maintain the position of the disc with respect to the tab portion;

a catch feature located on a first end of the tab portion and configured to snap fit with a fluid source through rotation of the tab portion; and

a latching feature located on a second end of the tab portion, the latching feature configured to interact and lock onto the fluid source through rotation of the tab portion as the catch feature snap fits with the fluid source;

wherein the disc is further configured to be displaced past the interference presented by the disc slot when a threshold force is applied to the tab portion; and

wherein the plug portion moves in the opposite direction of the threshold force, with respect to the tab portion.

2. The fluid connector assembly of claim 1, wherein the tab portion further comprises an indent configured to interact with a reusable housing assembly.

3. The fluid connector assembly of claim 1, wherein the catch feature comprises a ramp.

4. The fluid connector assembly of claim 1, wherein the fluid connector further comprises a tubing connected to the plug.

5. The fluid connector assembly of claim 4, wherein a first end of the tubing is connected to the plug and a second end of the tubing is connected to a cannula interface.

6. The fluid connector assembly of claim 1, wherein the tab portion further comprises a core on an underside of the tab portion, and the core further comprises an identification tag.

7. The fluid connector assembly of claim 1, wherein the tab portion comprises an identification tag.

8. The fluid connector assembly of claim 7, wherein the identification tag is an RFID tag.

9. The fluid connector assembly of claim 8, wherein the identification tag is a near-field communication readable RFID.

10. A fluid connector assembly comprising:

a tab portion comprising a disc retainer, a tubing side, and a fluid source side;

a plug portion slidably coupled to the tab portion and comprising a plug and a fluid path extending from a first end to a second end of the plug, the plug further comprising a disc extending radially therefrom and disposed intermediate the first and second end;

a catch feature located on a first end of the tab portion and configured to snap fit with a fluid source through rotation of the tab portion; and

a latching feature located on a second end of the tab portion, the latching feature configured to interact and lock onto the fluid source through rotation of the tab portion as the catch feature snap fits with the fluid source,

wherein a threshold force applied to the tab portion in the direction of the fluid source side causes the plug portion to move out of the disc retainer and in a direction opposite of the threshold force.

11. The fluid connector assembly of claim 10, wherein the tab portion further comprises an indent configured to interact with a reusable housing assembly.

12. The fluid connector assembly of claim 10, wherein the catch feature comprises a ramp.

13. The fluid connector assembly of claim 10, wherein the fluid connector further comprises a tubing connected to the plug.

14. The fluid connector assembly of claim 13, wherein a first end of the tubing is connected to the plug and a second end of the tubing is connected to a cannula interface.

15. The fluid connector assembly of claim 10, wherein an underside of the tab portion comprises a core.

16. The fluid connector assembly of claim 15, wherein the core comprises an identification tag.

17. The fluid connector assembly of claim 10, wherein the tab portion comprises an identification tag.

18. The fluid connector assembly of claim 17, wherein the identification tag is an RFID tag.

19. The fluid connector assembly of claim 18, wherein the identification tag is a near-field communication readable RFID.
