Abstract

A suction type urinating aid comprises a urine transport tube connected at one end through a urine detecting cylinder with a urine receiver provided with an air suction hole and a urine suction opening to be applied to a urinating region, and connected, at the other end, with a urine tank. A suction tube communicating to a vacuum device is connected to the upper part of the urine tank. The urine detecting cylinder is composed of a pair of electrodes placed at an interval inside an electrically insulating cylinder. Wires connected to the respective electrodes are connected to a control device of the vacuum device, so that when urine exists in the urine detecting cylinder, electric current flowing through the urine between the electrodes may be detected by the control device, to start the vacuum device by the control device.

Claims

1. A suction type urinating aid comprising:

a urine receiver having a urine suction opening adapted to be applied to the urinating region of a subject to receive therefrom urine, an air suction hole, and a urine outlet;

an electrically insulating cylinder connected to said urine outlet;

a urine tank;

a urine transport tube connected between said cylinder and said urine tank;

vacuum device means connected to said urine tank for drawing air into said urine receiver through said air suction hole therein and for drawing said air and any urine in said urine receiver through said urine outlet, said cylinder and said urine transport tube into said urine tank;

control means connected to said vacuum device means for controlling the operation therof;

detector means located in said cylinder, electrically connected to said control means, for detecting the presence of any urine in said cylinder and for causing said control means to operate said vacuum device means for drawing said air and urine from said urine receiver, said detector means comprising first and second ring-shaped electrodes positioned iinteriorly of said cylinder, said first and second electrodes being spaced from each other axially of said cylinder and electrically insulated from each other by said cylinder, said electrodes being positioned such that when urine exists in said cylinder, an electric current will flow through such urine between said electrodes and will be detected by said control means to start operation of said vacuum device means; and

the inner diameter of a cylindrical portion of said cylinder between said electrodes being equal to the inner diameter of said electrodes.

2. A vacuum suction type urinating aid as claimed in claim 1, wherein said control means includes a rectifier circuit, and wires extending from said electrodes are connected in series to the alternating current side of said rectifier circuit, so that alternating current may flow through urine between said electrodes, to generate a DC urine detection signal at the direct current side of said rectifier circuit.
