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.
Claims20
A corporeal drainage system, comprising:
- a connection tube;
- a fluid receptacle in fluid communication with the connection tube such that a bodily fluid may drain from the connection tube into an interior of the fluid receptacle, wherein the fluid receptacle has only one fold/seam around a perimeter of the fluid receptacle in a collapsed configuration and only one opening to the interior,
- the opening in fluid communication with the connection tube;
- wherein the connection tube connects to the fluid receptacle at the fold/seam;
- and
- activation members connected to an exterior surface of the fluid receptacle, the activation members configured to apply a pulling force to the fluid receptacle to initiate transitioning of the fluid receptacle from the collapsed configuration to an expanded configuration to thereby create a negative pressure in the system.

A corporeal drainage system, comprising:
- a connection tube;
- a fluid receptacle for receiving a bodily fluid having only one opening to its interior, 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;
- wherein the connection tube connects to the fluid receptacle on a side edge of flexible side walls;
- and
- an activation member configured to apply an external pulling force to the fluid receptacle, thereby creating a negative pressure in the system by transitioning the fluid receptacle from the collapsed configuration to an expanded configuration.
2 more elements
A corporeal drainage system, comprising:
- a connection tube;
- a flexible bag having only one opening to its interior, the opening in fluid communication with the connection tube such that a bodily fluid may drain from the connection tube into the interior of the flexible bag, wherein the flexible bag has only one fold/seam around a perimeter of the flexible bag in a collapsed configuration;
- wherein the connection tube connects to the flexible bag at the fold/seam;
- rigid members attached to opposing sides of the flexible bag;
- and
- activation members attached to an exterior surface of the rigid members, the activation members configured to apply an external pulling force to the flexible bag to initiate transitioning of the fluid receptacle from the collapsed configuration to an expanded configuration to thereby create a negative pressure in the system.
