Abstract For use in sterile drainage procedures, particularly in medicine and surgery and designed for insertion in the fluid communication line between a catheter and a sink, a rigid-walled jacket enclosing a dry chamber is introduced. This chamber is provided with upstream and downstream end intake and discharge ports respectively and contains a downstream-opening elongated elastomeric flutter valve secured to the upstream chamber-end in communication with said intake port. Manually operable pump means co-axial with the jacket and on the upstream side thereof also communicate with the said intake port. A cap may be integrally secured to the downstream end of the jacket to seal the intake aperture of an elastomeric collapsible sink in the form of a drainage container having a rigid upper wall in which said aperture is located, such rigid upper wall maintaining the upper parts of the collapsible side walls spaced apart to facilitate fluid reception.
In the practice of sterile drainage employing in fluid communication a catheter and a sink, the invention which comprises in combination, a rigid walled jacket enclosing a chamber having an inlet and an outlet, an elongated elastomeric one-way flutter valve within said chamber spaced from the surrounding jacket wall and openable towards said outlet, pump means between said catheter and said jacket in fluid communication with said catheter and jacket for effecting vacuum assisted downstream fluid drainage from a source to said sink, said pump means having an outlet port extending into said chamber through said inlet, said valve being secured on said outlet port.

Claim 4
Dependent Claim
95 words
The invention according to claim 2 in which a drainage container is secured to said cap, said drainage container being predominently elastomeric of normally flat collapsed configuration but having an upper wall portion at right angles to its major axial plane when collapsed which is rigid relative to the collapsible parallel side walls of said container, said relatively rigid upper wall portion extending upon diametrically opposite sides of an intake aperture formed to said upper wall portion bisected by said plane, an upwardly projecting mouth around said aperture, said cap being attachable to said mouth.
