Abstract

A control unit for a urinary relief system is disclosed herein. The control unit includes a pressure regulator having a high pressure inlet and a reduced pressure outlet, the high pressure inlet having a first air pressure, and the reduced pressure outlet having a second air pressure, an ejector having an pressurized air input, an vacuum port, and an air output, the pressurized air input of the ejector coupled to the reduced pressure outlet of the pressure regulator and the vacuum port connected to a storage device, an ejector head housing the pressure regulator and the ejector, and a pressurized gas source coupled to the high pressure inlet of the pressure regulator, the pressurized gas source providing an air flow having the first air pressure.

Claims (51)

1 . A control unit for a urinary relief system, comprising:

a pressure regulator having a high pressure inlet and a reduced pressure outlet, the high pressure inlet having a first air pressure, and the reduced pressure outlet having a second air pressure;

an ejector having a pressurized air input, a vacuum port, and an air output, the pressurized air input of the ejector coupled to the reduced pressure outlet of the pressure regulator and the vacuum port connected to an outlet port of a storage device;

an ejector head housing the pressure regulator and the ejector; and

a pressurized gas source coupled to the high pressure inlet of the pressure regulator, the pressurized gas source providing an air flow having the first air pressure.

2 . The control unit of claim 1 , wherein the second air pressure is about 25 times less than the first air pressure to about 35 times less than the first air pressure.

3 . The control unit of claim 1 , further comprising:

a valve disposed between the pressurized gas source and the pressure regulator, the valve configured to pass a gas from the pressurized gas source to the pressure regulator.

4 . The control unit of claim 3 , further comprising:

a toggle coupled to the valve, the toggle configured to activate the valve to release the gas from the pressurized gas source.

5 . The control unit of claim 4 , wherein the toggle is further configured to deactivate the valve, stopping the release of the gas from the pressurized gas source.

6 . The control unit of claim 1 , wherein the pressurized gas source includes one or more CO 2 cartridges.

7 . The control unit of claim 6 , further comprising:

one or more valves, each of the one or more valves being disposed between each CO 2 cartridge of the one or more CO 2 cartridges and the pressure regulator, each valve configured to pass pressurized CO 2 from each CO 2 cartridge to the pressurized gas source.

8 . A urinary relief system, comprising:

a human interface device;

a storage device having an inlet port and an outlet port, the storage device coupled to the human interface device via the inlet port; and

a control unit coupled to the storage device via the outlet port, the control unit including:

a pressure regulator having a high pressure inlet and a reduced pressure outlet, the high pressure inlet having a first air pressure, and the reduced pressure outlet has a second air pressure;

an ejector having a pressurized air input, a vacuum port, and an air output, the pressurized air input of the ejector coupled to the reduced pressure outlet of the pressure regulator and the vacuum port connected to the storage device;

an ejector head housing the pressure regulator and the ejector; and

a pressurized gas source coupled to the high pressure inlet of the pressure regulator, the pressurized gas source providing an air flow having the first air pressure.

9 . The urinary relief system of claim 8 , the control unit further comprising:

an air inlet port coupled to the ejector and to the storage device; and

an air outlet port coupled to the ejector.

10 . The urinary relief system of claim 9 , further comprising a flow restrictor coupled between the storage inlet port and the storage outlet port and wherein the control unit further comprises:

a connector having a first port and a second port, the connector configured to be removably coupled to the ejector head housing such that the first port is coupled to the air inlet port and the second port is coupled to the air outlet port.

11 . The urinary relief system of claim 8 , wherein the second air pressure is about 30 times less than the first air pressure.

12 . The urinary relief system of claim 8 , the control unit further comprising:

a pressurized gas housing to house the pressurized gas source, the pressurized gas housing configured to be removably coupled to the ejector head housing.

13 . The urinary relief system of claim 8 , the control unit further comprising:

a valve disposed between the pressurized gas source and the pressure regulator, the valve configured to pass a gas from the pressurized gas source to the pressure regulator.

14 . The urinary relief system of claim 8 , wherein the pressurized gas source includes one or more CO 2 cartridges.

15 . A urinary relief system, comprising:

a human interface device;

a storage device having an inlet port and an outlet port, the storage device coupled to the human interface device via the inlet port; and

a control unit coupled to the storage device via the outlet port, the control unit including:

an ejector head housing having an air inlet port and an air outlet port, the air inlet port coupled to the storage device;

a first pressurized gas housing removably coupled to the ejector head housing;

a first pressurized gas source disposed in the first pressurized gas housing;

a pressure regulator disposed in the ejector head housing, the pressure regulator coupled to the first pressurized gas source; and

an ejector coupled to the pressure regulator, the air inlet port, and the air outlet port.

16 . The urinary relief system of claim 15 , wherein the pressure regulator includes a high pressure inlet receiving a gas having a first pressure and a reduced pressure outlet outputting the gas having a second pressure that is less than the first pressure.

17 . The urinary relief system of claim 16 , wherein the second pressure is about 15 times less than the first pressure to about 45 times less than the first pressure.

18 . The urinary relief system of claim 15 , further comprising:

a second pressurized gas housing removably coupled to the first pressurized gas housing; and

a second pressurized gas source disposed in the second pressurized gas housing.

19 . The urinary relief system of claim 15 , the first pressurized gas housing further comprising:

a first valve coupled to the first pressurized gas source and to the pressure regulator when the first pressurized gas housing is coupled to the ejector head housing; and

a first toggle disposed on an outside surface of the first pressurized gas housing, the first toggle coupled to the first valve and configured to open the first valve in response to being toggled.

20 . The urinary relief system of claim 15 , wherein the first pressurized gas housing is configured to allow replacing the first pressurized gas source.
