摘要： A catheter suitable for use in performing peritoneal dialysis. The catheter is a dual lumen catheter which allows for continuous flow peritoneal dialysis. Dialysate flows through the catheter into the patient via one lumen and simultaneously flows through the catheter out of the patient via the second lumen. The dual lumen dialysis catheter has a flexible tube which has an implantable portion extending from an external patient portion. Both of the lumens have openings in the external patient portion for connecting to a supply and drain of dialysate, respectively. The implantable portion has a preformed curved segment which has an outlet for the first lumen to flow dialysate into the patient's peritoneal cavity. The implantable portion has an opening for the second lumen at the distal end to flow dialysate out of the peritoneal cavity and removal from the patient. The catheter facilitates mixing of fresh and spent dialysate inside the peritoneal cavity by inflowing fresh dialysate into the cavity at a location substantially separated from the cavity outflow location, and by directing the inflow of dialysate into the cavity opposite the cavity outflow location.

摘要： A device for recovering fluid from a reservoir having a lower drain. The device includes a first coupling connectable to a drain of a reservoir and having an internal passage for fluid flow therethrough. A conduit has one end connected to the first coupling for fluid flow into the conduit and a second end opposite the first end with a valve to control fluid flow through the conduit. A probe, defining a fluid passage, has a tip portion for actuating the valve from its normally closed position to an open position upon insertion of the tip portion in the valve to allow fluid flow through the valve and the probe. A portable receptacle is attached to the probe for collecting fluid when the valve is actuated to the open position. A portable pump reduces the pressure in the receptacle to draw fluid through the conduit and into the receptacle. The conduit includes a multi-layer construction wherein the inner layer includes material for reducing friction to enhance fluid flow and an outer later for protecting the inner layer.
