Abstract

An irrigation system including a reservoir with an inlet adapted to guide liquid into the reservoir, the inlet defining a closure for closing the inlet, an insertion member defining an insertion end sized for insertion into a body cavity of a human being, the insertion member defining at least one opening, and a liquid tube fluidly connecting the reservoir with the insertion member, at least one of the reservoir and the insertion member being permanently fastened to the liquid tube and further including an electrical pump adapted to pump liquid from the reservoir and out through the at least one opening of the insertion member, the electrical pump adapted to be separable from the system.

First claim

The invention claimed is:

1. An irrigation system for irrigation of a body cavity, the irrigation system comprising:
a reservoir with an inlet into the reservoir and a first non-return valve preventing liquid from exiting the reservoir through the inlet;
an insertion member insertable into an anus of a human, the insertion member defining an opening, the insertion member including a balloon for retaining the insertion member in the body cavity when inserted through the body opening;
a liquid tube fluidly connecting the reservoir with the insertion member, with at least one of: the reservoir and the insertion member permanently fastened to the liquid tube; and
an electrical pump adapted to pump liquid out of the reservoir and through the opening of the insertion member and adapted to be separated from the system, wherein the electrical pump is a liquid pump including:
a switch defining at least a first position in which the electrical pump is fluidly connected to the balloon such that operation of the electrical pump when the switch is in the first position causes the balloon to expand, and a second position in which the electrical pump is fluidly connected to the reservoir; and
a control unit adapted to control liquid flow in the system, wherein the control unit is adapted to change the flow rate of the liquid in a predetermined sequence and to operate the sequence repeatedly to stimulate the irrigation process.

2. The irrigation system according to claim 1 , wherein the inlet defines inclined surfaces guiding the liquid into the reservoir.

3. The irrigation system according to claim 1 , wherein the electrical pump is a peristaltic pump adapted to pump liquid through the tube without contacting the liquid.

4. The irrigation system according to claim 1 , wherein the electrical pump further comprises a manually operable generator comprising a crank which when operated causes the generator to charge a rechargeable battery of the electric pump.

5. The irrigation system according to claim 1 , wherein the liquid tube is a foil tube and sidewalls of the foil tube are moveable towards and into contact with each other before and after use.

6. A method of performing an irrigation of a body cavity of a human being by use of an irrigation system according to claim 1 , the method comprising:
delivering a liquid into the reservoir via the liquid inlet;
inserting the insertion member into a body cavity via a body opening of a human being;
operating the electrical pump and pumping at least a part of the liquid from the reservoir into the body cavity;
retracting the insertion member from the body cavity;
separating the electrical pump from the irrigation from the rest of the irrigation system; and
disposing of the rest of the irrigation system and retaining the electrical pump.

7. The method according to claim 6 , wherein operating the electrical pump includes varying the flow rated of the liquid over time in a predetermined sequence in order to stimulate the irrigation process.

8. An irrigation system for irrigation of a body cavity, the irrigation system comprising:
a reservoir with an inlet into the reservoir and a non-return valve preventing liquid from exiting the reservoir through the inlet;
an insertion member insertable into an anus of a human, the insertion member defining an opening, the insertion member including a balloon for retaining the insertion member in the body cavity when inserted through the body opening;
a liquid tube fluidly connecting the reservoir with the insertion member; and
an electrical pump adapted to pump liquid out of the reservoir and through the opening of the insertion member and adapted to be separated from the system, the electrical pump including:
an over-pressure valve fluidly connecting the electrical pump to the balloon until a pressure in the balloon reaches a predetermined pressure level, and fluidly connecting the electrical pump to the reservoir once the pressure in the balloon reaches the predetermined pressure level; and
a control unit adapted to control liquid flow in the system, wherein the control unit is adapted to change the flow rate of the liquid in a predetermined sequence and to operate the sequence repeatedly to stimulate the irrigation process.

9. The irrigation system according to claim 8 , wherein the electrical pump further comprises a manually operable generator comprising a crank which when operated causes the generator to charge a rechargeable battery of the electric pump.

10. An irrigation system for irrigation of a body cavity, the irrigation system comprising:
a reservoir with an inlet into the reservoir and a non-return valve preventing liquid from exiting the reservoir through the inlet;
an insertion member insertable into an anus of a human, the insertion member defining an opening, the insertion member including a balloon for retaining the insertion member in the body cavity when inserted through the body opening;
a liquid tube fluidly connecting the reservoir with the insertion member; and
an electrical pump adapted to pump liquid out of the reservoir and through the opening of the insertion member and adapted to be separated from the system, the electrical pump including:
a switch defining at least a first position in which the electrical pump is fluidly connected to the balloon such that operation of the electrical pump when the switch is in the first position causes the balloon to expand, and a second position in which the electrical pump is fluidly connected to the reservoir; and
a control unit adapted to control liquid flow in the system, wherein the control unit is adapted to change the flow rate of the liquid in a predetermined sequence and to operate the sequence repeatedly to stimulate the irrigation process.
