Abstract

A device for irrigating a body cavity is disclosed. The device comprises a first pump and a second pump being operatively linked via a manually-operated actuator member. The actuator member has at least a mode in which the actuator member activates the first pump to eject an initial volume of fluid out of the device, and a mode in which the actuator member activates the second pump to eject fluid out of the device and simultaneously activates the first pump to withdraw fluid into the device.

2. The device according to claim 1, wherein said actuator member additionally has a mode in which said actuator member activates only said first fluid pump to withdraw fluid from the body cavity.

3. The device according to claim 2, wherein said mode in which said actuator member simultaneously activates said first and said second pumps corresponds to a linear motion of said actuator member in a first direction, and wherein said mode in which said actuator member activates only said first fluid pump to withdraw fluid from the body cavity also corresponds to motion of said actuator member in a first direction.

4. The device according to claim 1, wherein said actuator member additionally has a mode in which both said pumps are inoperative.

5. The device of claim 1, wherein said first pump is configured to withdraw fluid to the body cavity at a first volumetric flow rate and said second pump is configured to withdraw fluid from the body cavity at a second volumetric flow rate, and wherein there is a linear relation between said first and said second volumetric flow rates.

6. The device according to claim 1, wherein said first pump is a first piston pump having a first piston, and said second pump is a second piston pump having a second piston.

7. The device of claim 6, wherein said first piston and said second piston are linked in a manner which enables independent movement of said first piston and said second piston through a preset movement range, and linked movement of said first piston and said second piston beyond said preset movement range.

8. The device according to claim 7, wherein movement of said first piston within said preset movement range delivers a first volume of fluid to the body cavity and further wherein movement of said second piston beyond said preset movement range delivers a second volume of fluid and operates said first piston to withdraw at least said second volume of fluid.

9. The device according to claim 6, wherein said piston pumps are aligned parallel to each other such that a withdrawing direction of said first piston pump is parallel to an ejecting direction of said second piston pump.

10. The device according to claim 9, further comprising a cogwheel configured for linking between a motion of said actuator member and a motion of said second piston.

11. The device according to claim 10, further comprising a first linear transmission element connected to said actuator member and configured to move together with said actuator member over a movement range selected such that said cogwheel engages said first linear transmission element over part of said range.

12. The device according to claim 11, further comprising a second linear transmission element connected to said piston of said second pump, wherein said cogwheel engages said second linear transmission element, such that linear motion of said second linear transmission element is established by rotary motion of said cogwheel.

13. The device according to claim 6, wherein said piston pumps are aligned parallel to each other such that a withdrawing direction of said first piston pump is opposite to an ejecting direction of said second piston pump.

14. The device according to claim 6, wherein said actuator member comprises a rotatable safety hatch configured to engage said first pump while rotating from a first orientation to a second orientation so as to activate said first pump to eject said initial volume of fluid, wherein while said safety hatch is at said first orientation both said pumps are inoperative.

15. The device according to claim 1, wherein at least one of said first and said second pumps is a peristaltic pump.

16. The device according to claim 1, wherein said first pump is a container having an under pressure therein.

17. The device according to claim 1, wherein said second pump is a deformable bag.

18. The device according to claim 1, further comprising a pressure measuring device.

19. The device according to claim 1, wherein at least one of said first and said second pumps comprises a biomarker therein.

20. A kit, comprising the device according to claim 1, and intubation device adapted for being introduced into the body cavity, wherein each of said first and said second pumps is connectable to a separate fluid line of said intubation device.

21. The kit according to claim 20, wherein said intubation device comprises:
