Abstract

A portable kidney dialysis system device is provided including a belt with a drain bag mounted thereon. A pump is also mounted on the belt and coupled between a user and the drain bag. The pump is adapted to pump fluid from the user to the drain bag upon the receipt of a drain signal. Further provided is a pressure switch for detecting when the drain bag is full. A control mechanism serves for transmitting the drain signal to the pump only when the means fails to detect that the drain bag is full.

Claims

1. A portable kidney dialysis system device comprising, in combination:

a belt;

a drain bag mounted on the belt and having an interior;

a pump mounted on the belt, a first tube being coupled to an inlet of the pump, the first tube being adapted for insertion into a body of a user, a second tube being coupled to an outlet of the pump and being in fluid communication with the interior of the drain bag, the pump being adapted to pump fluid from the first tube to the drain bag upon the receipt of a drain signal;

a motor for operating the pump;

detecting means operatively connected to the drain bag for detecting when the drain bag is full;

a timer; and

a control mechanism operatively coupled to the motor, the detecting means, and the timer, the control mechanism transmitting the drain signal to the pump only when the detecting means fails to detect that the drain bag is full, the control mechanism having a first mode for when the second tube is connected to the drain bag wherein the drain signal is transmitted for a predetermined amount of time to the motor intermittently at predetermined intervals for filling the drain bag with fluid from the body of the user.

2. A portable kidney dialysis system device as set forth in claims 1 wherein an outlet of the pump is further interchangeably coupleable to a fill bag when not connected to the drain bag and operation of the motor is reversible through a switch for the purpose of reversing the pumping direction of fluid to move fluid from the fill bag to the user.

3. A portable kidney dialysis system device as set forth in claim 2 wherein the pump is interchangeably releasably attachable to both the fill bag and drain bag via a similar tube releasably fluidly connectable to the outlet of the pump.

4. A portable kidney dialysis system device as set forth in claim 1 additionally comprising an audio means operatively connected to the detecting means for generating an audible signal when the drain bag is full.

5. A portable kidney dialysis system device as set forth in claim 1 wherein the control means transmits the drain signal to the pump only when fluid is available to be pumped from the user.

6. A portable kidney dialysis system device as set forth in claim 1 wherein the detecting means includes a pressure switch.

7. A portable kidney dialysis system device comprising, in combination:

a belt with an adjustable length and including a pair of free ends having a male and female couples attached thereto, respectively, for securing the belt on a user;

a drain bag pocket mounted on an outer surface of the belt and extending along ¾

of a length of the belt at a rear extent thereof, the drain bag pocket including a lid integrally coupled to a top edge of the belt with a pile fastener mounted thereon for releasably coupling with a pile fastener mounted on a front face of the drain pocket along an entire length thereof;

a drain bag having a length equal to ¾

that of the belt and a width equal to that of the belt, the drain bag having an end with a flexible tube coupled thereto and extending therefrom thus terminating with a couple including a rigid tube with a pair of gripping ears extending radially therefrom and a pair of diametrically opposed coupling protrusions;

a pump mounted on an outer surface of the belt adjacent to an end of the drain bag pocket, a first flexible tube being coupled to an inlet of the pump and being adapted for insertion into a body of a user, and a second flexible tube coupled to an outlet of the pump and terminating with a couple including a rigid tube with a pair of gripping ears extending radially therefrom and a pair of diametrically opposed coupling slots formed in an inner surface thereof for coupling with the couple of the drain bag and that of a fill bag which is filled with fluid, wherein the pump is adapted to pump fluid from the first flexible tube to the second flexible tube only upon the receipt of a drain signal and further pump fluid from the second flexible tube to the first flexible tube only upon the receipt of a fill signal;

a pressure sensor mounted in the second flexible tube for providing a full signal only upon the detection of a pressure exceeding a predetermined amount;

a flow sensor mounted in the second flexible tube for providing a flow signal only upon the detection of a flow of fluid;

audio means for generating an audible signal only upon the actuation of the audio means;

a timer; and

control means mounted on the outer surface of the belt and connected between the pump, the pressure sensor, the flow sensor, audio means, the timer and a manual switch, the control means having a first mode for when the drain bag connected to the second flexible tube of the pump wherein the drain signal is transmitted for a predetermined amount of time to the motor intermittently at predetermined intervals for filling the drain bag with fluid from the body of the user, whereby upon the receipt of the flow signal, the drain signal is continuously transmitted until the receipt of either the full signal or the lack of receipt of the flow signal, wherein the control means only actuates the audio means upon receipt of the full signal, the control means further having a second mode only upon the closing of the manual switch for when the second flexible tube of the pump is connected to the fill bag for transmitting the fill signal to the pump for inserting fluid from the fill bag within the body of the user.
