Abstract

A foot operated irrigation pump and flow control device for controlling the flow of irrigation fluid to a medical instrument. The device includes a flow control unit that is operable by an operator'"'"'s foot to control a flow rate of fluid through a passageway therethrough, and a pump unit that is in fluid connection with the flow control unit and which is operable by an operator'"'"'s foot to selective pump fluid out of the pump unit.

Claims

1. A foot operated irrigation pump and flow control device for controlling the flow of irrigation fluid to a medical instrument, comprising:

a flow control unit that is operable by an operator'"'"'s foot to control a flow rate of fluid through a passageway therethrough; and

a pump unit that is in fluid connection with the flow control unit and which is operable by an operator'"'"'s foot to selective pump fluid out of the pump unit.

2. The foot operated irrigation pump and flow control device of claim 1, wherein the flow control unit comprises a roller, a roller housing, and a platform, and wherein the flow control unit is adapted to be placed on a floor surface so that the roller can be manipulated by a user'"'"'s foot, and depending on which direction the roller is rolled, it will selectively open and close off the passageway to control the flow of fluid through the passageway.

3. The foot operated irrigation pump and flow control device of claim 1, wherein the pump unit comprises a platform and a squeeze bulb, the pump unit being adapted to be placed on a floor surface and compressed by a user'"'"'s foot to pump fluid therethrough.

4. The foot operated irrigation pump and flow control device of claim 3, wherein the passageway through the flow control unit comprises tubing connected at one end to a fluid supply, and which is connected at another end to an ingress end of the squeeze bulb.

5. The foot operated irrigation pump and flow control device of claim 1, wherein the flow control unit and the pump unit each have connectors for connecting the flow control unit and the pump unit side-by-side.

6. The foot operated irrigation pump and flow control device of claim 1, wherein one of the flow control unit and the pump unit connects to cystoscope or ureteroscope via tubing, and the other of the flow control unit and the pump unit connects to a fluid supply.

7. The foot operated irrigation pump and flow control device of claim 1, wherein the pump unit comprises a squeeze bulb that is formed in whole or in part of transparent material.

8. The foot operated irrigation pump and flow control device of claim 1, wherein the foot operated irrigation pump and flow control device can be used with irrigation from gravity and/or irrigation from under external pressure from another pump.

9. The foot operated irrigation pump and flow control device of claim 1, wherein the flow control unit has two positions, either on, wherein the fluid flow therethrough is unimpeded, or off, wherein no fluid will flow through the irrigation flow control unit.

10. The foot operated irrigation pump and flow control device of claim 9, wherein the flow control unit comprises a clamp that catches and releases in an on/off fashion with foot compression.

11. The foot operated irrigation pump and flow control device of claim 1, wherein the pump unit comprises a squeeze bulb that includes an internal spring to aid in re-expanding the squeeze bulb when external foot pressure is removed.

12. The foot operated irrigation pump and flow control device of claim 1, wherein the flow control unit and the pump unit are adapted to minimally or not at all impede with fluid flow therethrough when the flow control unit is in an open position.

13. A foot operated irrigation pump and flow control device for controlling the flow of irrigation fluid to a medical instrument, comprising:

a flow control unit that is operable by an operator'"'"'s foot to turn on or off fluid flow through a passageway therethrough; and

a pump unit that is in fluid connection with the flow control unit and which is operable by an operator'"'"'s foot to selective pump fluid out of the pump unit.

14. The foot operated irrigation pump and flow control device of claim 13, wherein the pump comprises a squeeze bulb that is formed in whole or in part of transparent material.

15. The foot operated irrigation pump and flow control device of claim 13, wherein the pump unit comprises a squeeze bulb that includes an internal spring to aid in re-expanding the squeeze bulb when external foot pressure is removed.

16. The foot operated irrigation pump and flow control device of claim 13, wherein the flow control unit and the pump unit are adapted to minimally or not at all impede with fluid flow therethrough when the flow control unit is in an open position.
