wherein the first and second sidewalls and the first and second flexure members together generally surround the first and second connector ports.

3. The connection device of claim 2, wherein:

the first and second flexure members are flexible tabs each comprising an internal surface that faces the first and second connector ports, and

the first and second catch mechanisms are each a shoulder protruding from an external surface of the first and second flexure members and configured to engage a complementary lip on the control unit; and wherein when the first and second flexure members flex inwards towards the first and second connector ports, the first and second catch mechanisms are released from engagement with the lip on the control unit.

4. The connection device of claim 1 , 2, or 3, the connection device further comprising a rib that is attached at its ends to the first and second connector ports and that extends from the planar base member towards the first ends of the first and second connector ports and increases rigidity of the connection device.

5. The connection device of claim 4, wherein the rib includes at least one tab that limits movement of the first and second flexure members so as to prevent the first and second flexure members from contacting the first and second connector ports when the first and second flexure members flex inwards toward the first and second connector ports.

6. The connection device of claim 1 , 2, 3, 4, or 5, wherein the first longitudinal channel is substantially parallel to the second longitudinal channel.

7. The connection device of claim 1 , 2, 3, 4, or 5, wherein the first and second flexure members each comprise a cambered contact surface.

8. The connection device of claim 1 , 2, 3, 4, or 5, wherein the first connector port acts as a female connector and the first tubing is received in the first longitudinal channel.

9. The connection device of claim 1 , 2, 3, 4, or 5, wherein the first connector acts as a male connector and the first tubing is received around an outer diameter of the first connector.

10. The connection device of claim 1 , 2, 3, 4, or 5, wherein when the connection device is released from the control unit, the first and second valves are configured to prevent leakage from the first and second tubing.

1 1 . The connection device of claim 1 , 2, 3, 4, or 5, wherein the first connector port is configured to be coupled to the first tubing to receive a warming fluid from the outlet port of the control unit and allow the warming fluid to flow to a patient warming device.

12. The connection device of claim 1 , 2, 3, 4, or 5, wherein the second connector port is configured to be coupled to the second tubing to receive a warming fluid from a patient warming device and allow the warming fluid to flow into the inlet port of the control unit.

13. The connection device of claim 1 , 2, 3, 4, or 5, wherein the planar base member further comprises an external bottom surface including a communication target that, when then the connection device is properly secured to the control unit, communicates to the control unit that the connection device is properly secured.

14. A method for releasably connecting a patient warming device to a control unit in a patient warming system, the method comprising:

connecting a first tubing to a first connector port of a connection device by coupling the first tubing to a first end of the first connector port, the first connector port comprising a wall that circumferentially defines a first longitudinal channel;

connecting a second tubing to a second connector port of the connection device by coupling the second tubing to a first end of the second connector port, the second connector port comprising a wall that circumferentially defines a second longitudinal channel;

aligning a first valve in the first longitudinal channel nearer a second end of the first connector port, wherein the first valve is configured to receive an outlet port of a control unit of the patient warming system;

aligning a second valve in the second longitudinal channel nearer a second end of the second connector port, wherein the second valve is configured to receive an inlet port of the control unit of the patient warming system; and

inserting the connection device into a receiving portion of the control unit of the patient warming device until a shoulder protruding from a first flexure member of the connection device engages a complementary lip on the receiving portion of the control unit to releasably secure the connection device in the receiving portion of the control unit.

15. The method of claim 14, wherein inserting the connection device into the receiving portion of the control unit further comprises:

sliding a first sidewall and a second sidewall opposite the first sidewall of the connection device along a direction of insertion into the receiving portion of the control unit, wherein each of the first sidewall and the second sidewall extends from the planar base member towards the first ends of the first and second connector ports;

flexing the first flexure member inwards towards the first and second connector ports to allow the shoulder protruding from the first flexure member to pass the complementary lip as the connection device is moved in the direction of insertion;

flexing a second flexure member inwards towards the first and second connector ports, wherein the second flexure member is opposite the first flexure

member and extends from the planar base member towards the first ends of the first and second connector ports, the second flexure member further comprising an other shoulder configured to engage an other complementary lip on the receiving portion of the control unit; wherein the first and second sidewalls and the first and second flexure members together generally surround the first and second connector ports and provide rigidity to the connection device.

16. The method of claim 15, further comprising squeezing the first and second flexure members inwards towards each other and pulling the connection device in a direction opposite the direction of insertion until the shoulder of the first flexure member and the other shoulder of the second flexure member slide past the complementary lip and other complementary lip of the receiving portion to allow the connection device to be released from the receiving portion of the control unit.

17. The method of claim 14, 15, or 16, wherein coupling the first tubing to the first end of the first connector port comprises: inserting the first end of the connector port into the first tubing or inserting the first tubing into the first end of the first connector port.

18. The method of claim 14, 15, or 16, further comprising:

inserting the connection device into the receiving portion of the control unit until an external bottom surface of the planar base member; and

when a communication target on the external bottom surface reaches a threshold proximity with a sensor of the receiving portion, communicating to the control unit that the connection device is properly secured to the control unit.

19. The method of claim 14, 15, or 16, wherein coupling the first tubing to the first end of the first connector port and coupling the second tubing to the first end of the second connector port creates a sealed fluid system comprising the connection device, the first and second tubing, and a patient warming device in fluid connection with the first and second tubing.

20. The method of claim 19, wherein aligning the first valve in the first longitudinal channel nearer the second end of the first connector port comprises inserting a first self-sealing valve into the first longitudinal channel to prevent a warming fluid from flowing out of the sealed fluid system through the first self-sealing valve, and aligning the second valve in the second longitudinal channel nearer the second end of the second connector port comprises inserting a second self-sealing valve into the second longitudinal channel to prevent a warming fluid from flowing out of the sealed fluid system through the second self-sealing valve.
