Abstract
A corporeal drainage system including a fluid receptacle. The fluid receptacle in one embodiment is disposable and may be manipulated to generate a negative fluid pressure. The fluid receptacle in another embodiment is reusable and includes features to enable the insertion of a disposable bag therein. A pump may be integral to the fluid receptacle, the pump including a pair of unidirectional check valves. A catheter connection system is described, which facilitates connection between a fluid flow conduit and an implanted catheter. Methods of producing active and passive siphon systems are also disclosed.
Claims21
A corporeal drainage system, comprising:
- an implantable catheter;
- a connection tube;
- a connection system, including a catheter connector attached to a proximal end of the catheter and a drainage line connector attached to a distal end of the connection tube;
- a fluid receptacle;
- and
- a pump including a first unidirectional check valve and a second unidirectional check valve, wherein the first unidirectional check valve is positioned at one end of the pump to connect the pump to the fluid receptacle and the second unidirectional check valve is positioned at an opposite end of the pump to connect the pump to the connection tube.
A corporeal drainage system, comprising:
- a catheter including a catheter connector at a proximal end thereof;
- a connection tube including a drainage line connector at a distal end thereof, the drainage line connector and catheter connector being configured for sealing attachment to one another;
- and
- a disposable fluid receptacle in fluid communication with the connection tube, the fluid receptacle being configured to create a negative pressure within the system upon activation thereof.
A method of draining fluid from a bodily cavity using a corporeal drainage system, the system including a fluid receptacle, comprising:
- attaching a connection tube to the proximal end of an implanted catheter;
- initiating a negative pressure in the system such that fluid flows from the bodily cavity in a direction toward the proximal end of the catheter;
- and
- placing the fluid receptacle at a level below the bodily cavity.
A corporeal drainage system, comprising:
- catheter means for direct access of a bodily cavity;
- conduit means for transporting fluid from the catheter means;
- a connection system, including a catheter connector attached to a proximal end of the catheter means and a drainage line connector attached to a distal end of the conduit means;
- receptacle means for holding fluid drained from the bodily cavity;
- and
- pump means for creating a negative pressure in the system.
