Abstract

A disposable manual irrigation pump system comprises a manual foot pump operatively coupled to a fluid reservoir and an associated intraprocedural device. The pump system is configured to provide a substantially continuous fluid supply at a desired flow rate from the fluid reservoir to the associated intraprocedural device along a first direction without backflow of fluid along a direction opposite the first direction.

Claims (25)

1. A disposable manual irrigation pump system comprising:

a manual foot pump configured to be coupled to a fluid reservoir and an intraprocedural device, the foot pump being configured to draw fluid from the fluid reservoir into the foot pump to substantially fill the foot pump as the foot pump moves from a deformed state to an un-deformed state;

a first one-way valve disposed between the foot pump and the reservoir;

a first liquid supply tube disposed between the pump and the reservoir and a second liquid supply tube disposed between the pump and the intraprocedural device;

a connector configured to couple an end of the first liquid supply tube and an end of the second liquid supply tube to the pump;

wherein the pump system is configured to provide a substantially continuous fluid supply at a desired flow rate from the fluid reservoir to the intraprocedural device along a first direction and the one-way valve is configured to prevent backflow of fluid along a direction opposite the first direction;

wherein the connector is a Y-connector having one opening coupled to the first liquid supply tube, one opening coupled to the second liquid supply tube, and one opening coupled to the pump; and

wherein the pump includes a single opening, the single opening being connected to the Y-connector.

2. A disposable manual irrigation pump system comprising:

a manual foot pump configured to be coupled to a fluid reservoir and an intraprocedural device, the foot pump being configured to draw fluid from the fluid reservoir into the foot pump to substantially fill the foot pump as the foot pump moves from a deformed state to an un-deformed state; and

a first one-way valve disposed between the foot pump and the reservoir;

wherein the pump system is configured to provide a substantially continuous fluid supply at a desired flow rate from the fluid reservoir to the intraprocedural device along a first direction and the one-way valve is configured to prevent backflow of fluid along a direction opposite the first direction; and

wherein the pump includes a single opening through which fluid is received in the pump from the reservoir and through which fluid is delivered from the pump to the intraprocedural device.

3. The disposable manual irrigation pump system of claim 2 , further comprising a first liquid supply tube disposed between the pump and the reservoir and a second liquid supply tube disposed between the pump and the intraprocedural device.

4. The disposable manual irrigation pump system of claim 3 , further comprising a connector configured to couple an end of the first liquid supply tube and an end of the second liquid supply tube to the pump.

5. The disposable manual irrigation pump system of claim 4 , further comprising a second one-way valve disposed between the pump and the intraprocedural device, wherein the second one-way valve allows fluid to flow from the pump to the intraprocedural device without backflow of fluid from the intraprocedural device to the pump.

6. The disposable manual irrigation pump system of claim 5 , wherein the first one-way valve allows fluid to flow from the reservoir to the pump without backflow of fluid from the pump to the reservoir.

7. The disposable manual irrigation pump system of claim 4 , wherein the connector is a Y-connector having one opening coupled to the first liquid supply tube, one opening coupled to the second liquid supply tube, and one opening coupled to the pump.

8. The disposable manual irrigation pump system according to claim 3 , further comprising an irrigation valve configured to couple the intraprocedural device and the second liquid supply tube.

9. The disposable manual irrigation pump system according to claim 2 , further comprising a connector disposed between the pump and the reservoir, wherein the connector is configured to insure the fluid flow is unimpeded through first liquid supply tube.

10. The disposable manual irrigation pump system according to claim 8 , further comprising a third liquid supply tube disposed between the second liquid supply tube and the irrigation valve, wherein the third liquid supply tube is configured to couple the second liquid supply tube and the irrigation valve.

11. The disposable manual irrigation pump system according to claim 10 , further comprising a coupler, wherein the coupler is configured to retain the second and third liquid supply tubes.

12. The disposable manual irrigation pump system of claim 2 , further comprising a cap having threads suitable for coupling to a fluid reservoir having a first diameter and a stopper or second cap having threads suitable for coupling to a fluid reservoir having a second diameter.

13. The disposable manual irrigation pump system of claim 12 , wherein the cap further includes an air vent configured to allow air to flow into the fluid reservoir.

14. The disposable manual irrigation pump system of claim 12 , further comprising a liquid supply tube disposed in an opening of the cap.
