Abstract

A portable pump apparatus for use in CAPD is provided as well as a method for providing CAPD to a patient. The portable pump apparatus for CAPD has a housing containing a pump, and a power supply, preferably a rechargeable battery, connected to the housing and electrically connected to drive the pump. A control knob on the housing is constructed and arranged to adjust the speed of the pump. A cover is mounted to the housing to enclose the pump. The cover has an inlet port and an outlet port to securely hold a tube thereunder. The portable pump apparatus for CAPD further has a display for providing drainage information and a clip so that the apparatus can be worn by a patient.

Claims

a housing that is so constructed and arranged that it can be worn by, or coupled to, a patient;

a single pump located in the housing and so constructed and arranged to assist in the fill step and the drain step;

a power supply located inside the housing and electrically connected to the single pump the power supply being sufficient in and of itself to energize the pump;

a length of tubing having a first end connectable to a container holding a fluid and a second end connectable to the patient;

a cover mounted to the housing to enclose the pump, the cover having an inlet port and an outlet port constructed and arranged to securely hold the tube against the housing restricting motion of the tube outside the cover;

means for processing operatively connected to the pump and the power supply; and

means for determining urea clearance data connected to the means for processing.

2. The portable pump apparatus for CAPD of claim 1 wherein the means for processing is a microprocessor.

3. A portable pump apparatus that can be worn by or coupled to a patient for a continuous ambulatory dialysis treatment that includes a fill and a drain step comprising:

a housing so constructed and arranged that it can be supported on a patient;

a single pump located in the housing and so constructed and arranged to assist in the fill and drain step;

a power supply located inside the housing and electrically connected to the pump, the power supply comprising batteries, to energize the pump;

a length of tubing having a first end connectable to a container holding a fluid and a second end connectable to the patient;

a cover mounted to the housing to enclose the pump, the cover having an inlet port and an outlet port constructed and arranged to securely hold the tube against the housing restricting motion of the tube outside the cover;

means for processing operatively connected to the pump and the power supply; and

means for measuring CAPD data connected to the means for processing.

4. A portable pump apparatus for CAPD of claim 3 further comprising:

means for storing CAPD data connected to the means for processing.

5. A portable wearable pump apparatus for a continuous ambulatory dialysis treatment that includes a fill and a drain step comprising:

a housing that is so constructed and arranged that it can be carried by or on a patient;

a single pump located in the housing for pumping fluid into and out of the patient;

a power supply located inside the housing and electrically connected to the pump to energize the pump without the need for coupling the pump to an outside electrical source;

a length of tubing having a first end connectable to a container holding a fluid and a second end connectable to the patient;

a cover mounted to the housing to enclose the pump, the cover having an inlet port and an outlet port constructed and arranged to securely hold the tube against the housing restricting motion of the tube outside the cover;

means for processing operatively connected to the pump and the power supply; and

an alarm means connected to the means for processing.

6. A portable wearable pump apparatus for conducting CAPD by pumping a fluid into a patient and an effluent out of a patient, the apparatus comprising:

a housing having a planar exterior wall partially defining the housing and a member for coupling the pump to an item of a patient'"'"'s clothing;

a power source in the interior of the housing for supplying power to the pump without the need for an external source of power;

a single pump located in the housing, and electrically connected to the power source;
