Abstract

A corporeal drainage system and a method of draining fluid from a bodily cavity. The corporeal drainage system includes a connection tube and a fluid receptacle in fluid communication with the connection tube. The fluid receptacle creates a negative pressure in the system by transitioning from a collapsed configuration to an expanded configuration. The system may include an activation member to initiate transitioning of the fluid receptacle.

Claims

1. A method of draining fluid from a bodily cavity, comprising:

providing a corporeal drainage system including a flexible connection tube and a fluid receptacle having only one opening to an interior thereof, the opening in fluid communication with the connection tube, the fluid receptacle having an initial rest state in a fully or approximately fully collapsed configuration before any force is applied;

further including a first activation member and a second activation member;

creating a negative pressure by transitioning the fluid receptacle from the collapsed configuration to an expanded configuration, the transitioning including activating the first and second activation members; and

drawing fluid from the bodily cavity into the connection tube.

2. The method according to claim 1, wherein the transitioning further comprises placing the fluid receptacle at a level below the bodily cavity.

3. The method according to claim 1, wherein the activating includes pulling two opposing sides of the fluid receptacle away from one another.

4. The method according to claim 1, wherein the first and second activation members are configured to move orthogonal to a central axis of the connection tube.

5. The method according to claim 1, wherein the fluid receptacle comprises flexible side walls, the method further comprising connecting the connection tube to the fluid receptacle on a side edge of the flexible side walls.

6. The method according to claim 1, wherein the connection tube is connected to a catheter.
