Abstract

Abstract Apparatus for use in training the bladder of an incontinent patient including a pressure chamber connectable to the bladder with a catheter and a collecting container connected to the pressure chamber by a narrow tube. The pressure chamber is to be lower than the bladder and the collecting container is below the pressure chamber, while the tube extends upwardly from the pressure chamber. In use, the pressure chamber fills up, pressurizing the bladder, until urine reaches the highest part of the tube whereon the pressure chamber and bladder are emptied and the pressure reduced.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 148 words
Apparatus for continuously emptying the urine bladder while at the same time training the bladder of an incontinent patient, comprising a pressure chamber locatable below the bladder and having an inlet at its upper end connectable to said bladder, a collecting container connected to said pressure chamber and located below said pressure chamber, the connection between the pressure chamber and the collecting container being formed as a pipette to permit filling of said pressure chamber to a predetermined level, and force the air therein to escape through said inlet to achieve a gradual pressure increase in the bladder resulting in expansion thereof, followed by automatic emptying of bladder and pressure chamber resulting in a contraction of the urine bladder, and uni-directional valve means arranged in association with said pressure chamber to permit air to be introduced therein to equalize the partial vacuum occuring within said chamber after emptying.
Claim 2
Dependent Claim 148 words
Apparatus for continuously emptying the urine bladder while at the same time training the bladder of an incontinent patient, comprising a pressure chamber locatable below the bladder and having an inlet at its upper end connectable to said bladder, a collecting container connected to said pressure chamber and located below said pressure chamber, the connection between the pressure chamber and the collecting container being formed as a pipette to permit filling of said pressure chamber to a predetermined level, and force the air therein to escape through said inlet to achieve a gradual pressure increase in the bladder resulting in expansion thereof, followed by automatic emptying of bladder and pressure chamber resulting in a contraction of the urine bladder, and uni-directional valve means arranged in association with said pressure chamber to permit air to be introduced therein to equalize the partial vacuum occuring within said chamber after emptying.
Claim 3
Dependent Claim 19 words
Apparatus as claimed in claim 1, wherein said inlet is connected to said bladder by a tube and catheter.
Claim 4
Dependent Claim 18 words
Apparatus as claimed in claim 2, including an air tube connecting said uni-directional valve to said collecting container.
Claim 5
Dependent Claim 22 words
Apparatus as claimed in claim 3 wherein a part of said air tube is higher than the highest part of said pipette.
Claim 6
Dependent Claim 24 words
Apparatus as claimed in claim 2 including a closed air container and an air tube connecting said un-directional valve to said closed air container.
Claim 7
Dependent Claim 22 words
Apparatus as claimed in claim 5 wherein a part of said air tube is higher than the highest part of said pipette.
Claim 8
Dependent Claim 28 words
Apparatus as claimed in claim 1, wherein said pipette extends downwardly into proximity of the bottom of said pressure chamber and is provided with a widened flaring end.
Claim 9
Dependent Claim 13 words
Apparatus as claimed in claim 7, wherein said widened end is funnel shaped.
Claim 10
Dependent Claim 21 words
Apparatus according to claim 1 wherein at least said pressure chamber is formed with flexible walls responsive to changes in pressure.
Claim 11
Dependent Claim 77 words
Apparatus as claimed in claim 1, wherein at least one of said pressure chamber and collecting container comprises a bag of plastic material having sealed edges and at least one integral connecting member communicating for removably securing a connecting tube with the inside of the bag through a sealed edge, the connecting member being of oval cross-section where it passes through said sealed edge and being sealed in said sealed edge and being connected to a tube.
Claim 12
Dependent Claim 36 words
Apparatus as claimed in claim 10, wherein the unidirectional valve comprises an open ended tube of flexible material in said bag and surrounding said connecting member, said open ended tube being welded in said sealed edge.
Claim 13
Dependent Claim 20 words
The apparatus according to claim 1, wherein said uni-directional valve is connected to the upper part of the urine bag.
Claim 14
Dependent Claim 24 words
The apparatus according to claim 1, wherein said pressure chamber, the collecting container and said connection are displaceable arranged in relation to each other.
