Self-sealing connector for gel pads

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.
