Abstract

Claims (38)

1 . A targeted temperature management (TTM) system, comprising:

a TTM module configured to provide a TTM fluid;

a fluid delivery line (FDL) including a FDL hub, a fluid delivery lumen and a fluid return lumen; and

a pad configured to facilitate thermal energy transfer between the TTM fluid and a patient, the pad comprising:

a pad portion configured for placement on the patient,

a fluid delivery conduit extending away from the pad portion, the fluid delivery conduit including a delivery conduit connector at a proximal end thereof,

a fluid return conduit extending away from the pad portion, the fluid return conduit including a return conduit connector at a proximal end thereof, and

a connector coupled to a distal end of each of the fluid delivery conduit and the fluid return conduit, the connector including a flapper valve configured to alternate between an open position and a closed position based on whether the connector is coupled with the FDL hub, wherein:

the flapper valve includes a single deformable flapper member disposed within the connector,

the single deformable flapper member defines a flat shape extending across both a delivery opening and a return opening of the connector in the closed position, and

the coupling causes a protrusion of the FDL hub to displace the single deformable flapper member away from the delivery opening and the return opening, thereby deforming the single deformable flapper member away from the flat shape to a V-shape in the open position.

2 . The system of claim 1 , wherein the connector includes a connector housing having disposed therein proximal ends of the fluid delivery conduit and the fluid return conduit, a conduit partition separates the fluid delivery conduit, the fluid return conduit, and the flapper valve.

3 . The system of claim 2 , wherein the flapper valve is configured in the closed position for covering openings of each of the fluid delivery conduit and the fluid return conduit when the connector is uncoupled from the FDL hub.

4 . The system of claim 2 , wherein the connector is configured to receive the FDL hub upon coupling, causing the flapper valve to deform into the open position, wherein coupling the connector and the FDL hub establishes fluid communication therebetween.

5 . The system of claim 4 , wherein the flapper valve is configured to deform around the conduit partition.

6 . The system of claim 2 , wherein the conduit partition includes an aperture, and wherein the flapper valve is disposed in the aperture.

7 . The system of claim 6 , wherein each of a proximal side and a distal side of the aperture includes tapering to facilitate deformation of the flapper valve upon coupling of the connector and the FDL hub.

8 . The system of claim 1 , wherein the connector includes a top compression strip connected to a top latch and a bottom compression strip connected to a bottom latch, wherein each of the top latch and the bottom latch extends proximally from the connector.

9 . The system of claim 8 , wherein the top compression strip and the bottom compression strip are configured to cause movement of the top latch and the bottom latche in opposing directions upon application of pressure to the top compression strip and the bottom compressions strip.

10 . The system of claim 1 , wherein each of the fluid delivery lumen and the fluid return lumen include a distal conduit tip extending distally from the FDL hub.

11 . The system of claim 10 , wherein openings of the fluid delivery conduit and the fluid return conduit are configured to receive the distal conduit tip upon coupling the connector and the FDL hub.

12 . A targeted temperature management (TTM) pad to receive and circulate TTM fluid to facilitate thermal energy transfer between the TTM fluid and a patient, the TTM pad comprising:

a pad portion configured for placement on the patient,

a fluid delivery conduit extending away from the pad portion, the fluid delivery conduit including a delivery conduit connector at a proximal end thereof,

a fluid return conduit extending away from the pad portion, the fluid return conduit including a return conduit connector at a proximal end thereof, and

a connector coupled to a distal end of each of the fluid delivery conduit and the fluid return conduit, the connector including a flapper valve configured to alternate between the open position and the closed position based on whether the connector is coupled with a fluid delivery line (FDL) hub, wherein:

the flapper valve includes a single deformable flapper member disposed within the connector,

the single deformable flapper member defines a flat shape extending across both a delivery opening and a return opening of the connector in the closed position, and

the coupling causes a protrusion of the FDL hub to displace the single deformable flapper member away from the delivery opening and the return opening, thereby deforming the single deformable flapper member away from the flat shape to a V-shape in the open position.

13 . The TTM pad of claim 12 , wherein the connector includes a connector housing having disposed therein proximal ends of the fluid delivery conduit and the fluid return conduit, a conduit partition separates the fluid delivery conduit, the fluid return conduit, and the flapper valve.

14 . The TTM pad of claim 13 , wherein the flapper valve is configured in the closed position for covering openings of each of the fluid delivery conduit and the fluid return conduit when the connector is uncoupled from the FDL hub.

15 . The TTM pad of claim 13 , wherein the connector is configured to receive the FDL hub upon coupling, causing the flapper valve to deform into the open position, wherein coupling the connector and the FDL hub establishes fluid communication therebetween.

16 . The TTM pad of claim 12 , wherein the flapper valve is configured to deform around a conduit partition.

17 . The TTM pad of claim 12 , wherein a conduit partition includes an aperture, and wherein the flapper valve is disposed in the aperture.

18 . The TTM pad of claim 17 , wherein each of a proximal side and a distal side of the aperture includes tapering to facilitate deformation of the flapper valve upon coupling of the connector and the FDL hub.

19 . The TTM pad of claim 12 , wherein the connector includes a top compression strip connected to a top latch and a bottom compression strip connected to a bottom latch, wherein each of the top latch and the bottom latch extends proximally from the connector.

20 . The TTM pad of claim 19 , wherein the top compression strip and the bottom compression strip are configured to cause movement of the top latch and the bottom latche in opposing directions upon application of pressure to the top compression strip and the bottom compressions strip.

21 . The TTM pad of claim 12 , wherein upon coupling of the connector and the FDL hub, an opening of the fluid delivery conduit is configured to receive a distal conduit tip of the fluid delivery conduit and an opening of the fluid return conduit is configured to receive a distal conduit tip of the fluid return conduit.
