1. A corporeal drainage system, comprising:
- a catheter including a catheter connector at a proximal end thereof, the catheter connector including a tapered feature abutted by a deformable sealing element, the tapered feature in contact with the deformable sealing element in a closed configuration;
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, the drainage line connector including an actuating member that deforms the deformable sealing element such that the tapered feature is separated from the deformable sealing element in an open configuration; 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.

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.

8. 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, the catheter connector including a tapered feature abutted by a deformable sealing element and a drainage line connector attached to a distal end of the conduit means, the drainage line connector including an actuating member that deforms the deformable sealing element such that the tapered features is separated from the deformable sealing element in an open configuration; receptacle means for holding fluid drained from the bodily cavity; and pump means for creating a negative pressure in the system.
