System including suction regulator for automatically removing urine from a female patient
A system for automatically removing by suction urine voided by a female. The system includes an external catheter, a canister and a suction regulator. The external catheter is applied at the urethra opening to receive urine voided by the female. The canister collects the urine and is coupled to a source of suction having a first value. The suction regulator is interposed between the external catheter and the canister to regulate the amount of suction to a regulated value which is applied the external catheter, whereupon urine from the external catheter is carried through the suction regulator and into the canister. The system may also include an adapter or an adapter/splitter for connection between the source of suction and the canister.
1. A system for automatically removing by suction urine voided by a female comprising:
an external catheter configured for external disposition in fluid communication with a urethra opening of the female, whereupon urine voided by the female is received by said external catheter;
a receptacle or canister for collecting urine and configured to be coupled to a source of suction providing suction having a first value; and
a suction regulator interposed between said external catheter and said receptacle or canister to regulate the amount of suction from said first value to a regulated value lower than said first value and to apply regulated suction at said regulated value to said external catheter, wherein urine from said external catheter is carried through said suction regulator and into said receptacle or canister by air and wherein said suction regulator comprises a body and a sound suppressor, said body having a first passageway configured to be coupled to the external catheter, a second passageway configured to be coupled to the source of suction, and third passageway connecting said first and second passageways to result in a tortuous fluid flow path through said passageways, said sound suppressor being located in said second passageway for reducing the sound of air flowing through said suction regulator.
2. The system of claim 1 , wherein said second passageway is offset from said first passageway and interconnected thereto by a third passageway extending generally perpendicularly to said first and second passageways.
3. The system of claim 1 , wherein said sound suppressor comprises a tube having a multitude of small hook-like projections extending generally radially inward.
4. The system of claim 2 , wherein said sound suppressor comprises a tube having a multitude of small hook-like projections extending generally radially inward.
5. A system for automatically removing by suction urine voided by a female comprising:
an external catheter configured for external disposition in fluid communication with a urethra opening of the female, whereupon urine voided by the female is received by said external catheter;
a receptacle or canister for collecting urine and configured to be coupled to a source of suction providing suction having a first value;
a suction regulator interposed between said external catheter and said receptacle or canister to regulate the amount of suction from said first value to a regulated value lower than said first value and to apply regulated suction at said regulated value to said external catheter, whereupon urine from said external catheter is carried through said suction regulator and into said receptacle or canister; and an adapter configured to be coupled between the source of suction and said receptacle or canister, said adapter comprising an inlet, a valve and a first connector, said inlet being configured to be connected to the source of suction, said first connector being configured to be connected to said receptacle or canister, said valve being configured to be in either a closed state or an open state, whereupon when in said closed state said receptacle or canister is isolated from said inlet, and when in said open state suction at said first value is provided from said inlet to said first connector and to receptacle or canister.
6. The system of claim 5 , wherein said adapter includes an internal passageway having one end in communication with said inlet and another end in communication with said first connector, and wherein said valve includes a rotatable portion having an opening extending therethrough, said rotatable portion intersecting said internal passageway, whereupon when said rotatable portion is in a first rotatable position said rotatable portion blocks said internal passageway between said inlet and said first connector, and when said rotatable portion is in a second position said opening unblocks said internal passageway between said inlet and said first connector to enable suction at said first value to appear at said first connector.
7. The system of claim 5 , wherein said first connector is configured to have a first section of suction tubing having a first end connected to it and a second end connected to said receptacle or canister.
8. The system of claim 7 , wherein said first connector is a barbed bubble connector.
9. The system of claim 5 , wherein said adapter additionally comprises a splitter including a second connector having a passageway section in fluid communication with said internal passageway between said inlet and said valve, whereupon suction at said first value is available from said inlet to said second connector irrespective of the state of said valve.
10. The system of claim 9 , wherein said adapter includes an internal passageway having one end in communication with said inlet and another end in communication with said first connector, and wherein said valve includes a rotatable portion having an opening extending therethrough, said rotatable portion intersecting said internal passageway, whereupon when said rotatable portion is in a first rotatable position said rotatable portion blocks said internal passageway between said inlet and said first connector, and when said rotatable portion is in a second position said opening unblocks said internal passageway between said inlet and said first connector to enable suction at said first value to appear at said first connector.
