Abstract
Abstract A device for training a urine bladder which has lost its elasticity due to long term catheterization, whereby it comprises a pressure sensitivity system being arranged to the urethra catheter and a closing-opening unit being controlled by said pressure sensitivity system, which unit is arranged after the pressure sensitivity system seen from the urine bladder. A pressure, which is obtained in the catheter, actuates via the pressure sensitivity system a motor which is arranged to open and close the catheter by means of a mechanical clamping unit.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
A device for exercising a urine bladder into which a catheter has been inserted, comprising closing-opening means engaging said catheter, said closing-opening means being normally closed for preventing flow through said catheter, means for detecting the pressure in said catheter between said bladder and said closing-opening means, and actuation means coupled to the pressure detecting means for opening said closing-opening means for a pre-set time period to permit flow through said catheter in response to the detection of a predetermined pressure by said pressure detecting means, said pre-set time period being sufficient to permit said bladder to empty at least substantially, wherein said actuation means is adjustable for opening said closing-opening means at one of a plurality of predetermined pressures in said catheter.
Claim 2
Independent Claim
123 words
A device for exercising a urine bladder into which a catheter has been inserted, comprising closing-opening means engaging said catheter, said closing-opening means being normally closed for preventing flow through said catheter, means for detecting the pressure in said catheter between said bladder and said closing-opening means, and actuation means coupled to the pressure detecting means for opening said closing-opening means for a pre-set time period to permit flow through said catheter in response to the detection of a predetermined pressure by said pressure detecting means, said pre-set time period being sufficient to permit said bladder to empty at least substantially, wherein said actuation means is adjustable for opening said closing-opening means at one of a plurality of predetermined pressures in said catheter.
Claim 3
Dependent Claim
25 words
A device according to claim 1, wherein said actuation means comprises a revolution controlled motor and coupling means between said motor and said closing-opening means.
Claim 4
Dependent Claim
32 words
A device according to claim 2, wherein said closing-opening means comprises clamping means engaging said catheter and said coupling means is arranged to release said clamping means when said motor is actuated.
Claim 5
Dependent Claim
20 words
A device according to claim 1, wherein said actuation means comprises a time relay means for controlling said closing-opening means.
Claim 6
Dependent Claim
27 words
A device according to claim 4, wherein said closing-opening means comprises an electromechanically controlled membrane valve and wherein said time relay is arranged to control said valve.
Claim 7
Dependent Claim
21 words
A device according to claim 1, further comprising means communicating with said catheter for introducing a liquid into said urine bladder.
Claim 8
Dependent Claim
34 words
A device according to claim 1, wherein said actuation means is adjustable for opening said closing-opening means in response to a detected pressure between 0 and 750 mm. column of water in said catheter.
Claim 9
Dependent Claim
36 words
A device according to claim 2, wherein said motor and said coupling means are adapted to open said closing-opening means for a time period of 1-5 minutes upon actuation of said motor by said actuation means.
Claim 10
Dependent Claim
24 words
A device according to claim 4, wherein said time relay is adapted to open said closing-opening means for a time period of 1-5 minutes.
Claim 11
Dependent Claim
25 words
A device according to claim 1, comprising means for preventing opening of said closing-opening means in response to momentary surges of pressure in said catheter.
Claim 12
Dependent Claim
31 words
A device according to claim 10, wherein said means for preventing opening of said closing-opening means in response to momentary surges comprises a time delay means acting on said actuation means.
Claim 13
Dependent Claim
39 words
A device according to claim 1, comprising pressure equalizing means coupled to said catheter between said pressure detecting means and said bladder for preventing opening of said closing-opening means in response to momentary surges of pressure in said catheter.
