Abstract

An apparatus comprising a conduit clamping device with a closing mechanism for closing and opening passage of fluid or air in a flexible conduit is disclosed. The apparatus comprises a movable arm or disk that is connected to a manipulation arm or a knob; a conduit in form of a tube, that is laid flat against an abutment or protrusion; and a guide structure that constrains the movable arm or disk between the guide structure and the tube and being designed such that movement of the arm or disk will control the compression of the tube.

First claim

The invention claimed is:

1. An apparatus comprising a conduit clamping device with a closing mechanism for closing and opening passage of fluid or air in a flexible conduit, wherein the apparatus includes:
a housing;
a movable arm or disk, disposed in the housing and connected to a manipulation arm or a knob;
an abutment or protrusion extending from said housing;
a conduit in the form of a tube that is laid flat against said abutment or protrusion; and
a guide structure that constrains the movable arm or disk to movements between said guide structure and the tube and that is designed such that movement of the arm or disk will control the compression of the tube.

2. The apparatus according to claim 1 , wherein the guide structure is formed by a solid wall or top of the apparatus.

3. The apparatus according to claim 2 , wherein the solid wall or top has the form of a handle.

4. The apparatus according to claim 3 , wherein a valve is placed at a barrel end of the handle.

5. The apparatus according to claim 3 , wherein a hypodermic needle, or a drain tube or a catheter, is connected to the barrel end of the handle.

6. The apparatus according to claim 3 , wherein the hypodermic needle, or a drain tube or a catheter, is removably connectable to the mouth of the handle.

7. The apparatus according to claim 1 , wherein the guide structure is formed as a first elongate channel, and wherein the arm or disk comprises a second elongate channel, and wherein the knob or manipulation arm comprises a pin extending into said channels, and thereby controlling movement of said movable arm or disk.

8. The apparatus according to claim 7 , wherein the disk or arm is pivotable around a pivot, and wherein an abutment end is arranged at a distance from said pivot.

9. The apparatus according to claim 1 , wherein the movable arm or disk is arranged to be biased into two separate positions.

10. The apparatus according to claim 9 , wherein a spring, and preferably a spring plate, is arranged to bias the knob position into two positions.

11. The apparatus according to claim 9 , wherein the first elongate channel is essentially linear, and wherein the second elongate channel is curved into a concave shape, as seen from the abutment or protrusion.

12. The apparatus according to claim 9 , wherein the movement of the movable arm or disk, is arranged to be biased into a fully closed and a fully opened position, respectively.

13. The apparatus according to claim 1 , wherein a vacuum source is connected to the conduit.

14. The apparatus according to claim 1 , wherein the moveable arm or disk is integrally connected to the manipulation arm or knob.

15. The apparatus according to claim 1 , wherein the knob is maneuverable by means of one finger.

16. The apparatus according to claim 1 , further comprising a suction and collection device, wherein the suction and collection device is a vacuum vessel with a vacuum obtained in advance.

17. The apparatus according to claim 16 , wherein the vacuum vessel has a closable inlet stub, through which the vacuum vessel is connected to a free end of the conduit.

18. The apparatus according to claim 1 , wherein the apparatus is useable for at least one of the following: removal and supply of fluid or air, below skin level, at a human or an animal; removal of accumulations of fluid or air being a result of surgery; removal of accumulations of fluid in knees or other tissue with cavity; removal of fluid in regions of organs; removal of fluid in gastrointestinal regions; and removal of fluid in the heart/lungs.

19. The apparatus of claim 18 , wherein the apparatus further comprises a hypodermic needle for penetration of the skin and a suction and collection device for suction of the fluid through the hypodermic needle, or a drain tube or a catheter.

20. The apparatus of claim 18 , wherein the apparatus further comprises a device for adding fluid to the cavity with the purpose of infusion of medicine in the cavity or performing lavage of preformed cavity or as a result of prior surgery.

21. The apparatus of claim 1 , wherein the apparatus is used in an irrigation system.

22. The apparatus according to claim 1 , wherein the moveable arm or disk is held in a closed position by friction between the moveable arm or disk and the guide structure.

23. A conduit clamping device for closing and opening passage of fluid or air in a flexible conduit, comprising:
a housing;
a pivotable element, pivotable around a pivot connected to said housing, and having a protruding closing end;
a conduit in the form of a tube;
an abutment fixedly connected to said housing, wherein the conduit is arranged between the abutment and the protruding closing end;
a first elongate channel being arranged in said housing;
a second elongate channel being arranged in the pivotable element;
a pin extending through said first and second elongate channels and being displaceable within said channels; and
a manipulation arm or knob connected to said pin, for displacement of said pin within said channels;
whereby the first and second elongate channels are arranged to provide movement of said protruding closing end towards and away from said abutment upon displacement of said pin.

24. The conduit clamping device according to claim 23 , wherein at least one of said elongate channels is curved, thereby biasing movement of the moveable arm or disk.

25. The conduit clamping device according to claim 23 , wherein the first elongate channel is essentially linear, and wherein the second elongate channel has a concave profile.
