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.

First claim

What is claimed is:

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.
