Abstract

A system comprising: (a) a sheath configured to receive all or a portion of an endoscope; (b) an irrigation line connecting the sheath to an irrigation source; (c) a suction line connecting the sheath to a suction source; and (d) a control module located between the sheath, and the irrigation source and the suction source and controls flow of irrigation fluid from the irrigation source to the sheath and movement of suction between the suction source and the sheath; wherein the irrigation source is connected to a resilient reservoir that is located within the control module and movement of the control module compresses the resilient reservoir moving irrigation fluid from the resilient reservoir to the sheath so that the irrigation fluid assists in cleaning the endoscope, and wherein the control module includes a valve and compression of the resilient reservoir initiates movement of the valve so that the valve opens and suction from the suction line is applied to the sheath.

First claim

We claim:

1. A system comprising:
a) a sheath configured to receive all or a portion of an endoscope;
b) an irrigation line connecting the sheath to an irrigation source;
c) a suction line connecting the sheath to a suction source; and
d) a control module located between the sheath, and the irrigation source and the suction source, the control module controls flow of irrigation fluid from the irrigation source to the sheath and movement of suction between the suction source and the sheath, the control module comprising:
i) an actuation member;
ii) a resilient reservoir in communication with the irrigation line and the actuation member;
iii) a valve in communication with the suction line; and
iv) a controller in communication with the actuation member and the valve

wherein compression of the resilient reservoir with the actuation member moves irrigation fluid from the resilient reservoir to the sheath so that the irrigation fluid assists in cleaning the endoscope, and
wherein during the compression of the resilient reservoir, the actuation member also triggers a response from the controller which initiates movement of the valve so that the valve opens and suction from the suction line is applied to the sheath after the irrigation fluid begins moving from the resilient reservoir to the sheath but before the irrigation fluid stops moving from the resilient reservoir to the sheath.

2. The system of claim 1 , wherein the actuation member evenly applies compression to the resilient reservoir creating pressure that forces the irrigation fluid from the resilient reservoir.

3. The system of claim 1 , wherein the control module is a foot pedal.

4. The system of claim 3 , wherein the irrigation source applies a pressure to the resilient reservoir and assists in expanding the resilient reservoir.

5. The system of claim 3 , wherein the control module includes a base and the actuation member is movable relative to the base,
wherein the resilient reservoir, the valve, and the controller are supported on the base, and
wherein the actuation member is connected to the base by a pivot, and pivotally moves relative to the base during the compression of the resilient reservoir.

6. The system of claim 1 , wherein the resilient reservoir expands when compression is complete so that irrigation fluid ceases to be applied.

7. The system of claim 1 , wherein between the endoscope and the control module, the suction line and the irrigation line are connected with a common fitting, and a common line extends between the common fitting and the endoscope.

8. A system comprising:
a) a sheath configured to receive all or a portion of an endoscope;
b) an irrigation line connecting the sheath to an irrigation source;
c) a suction line connecting the sheath to a suction source; and
d) a foot pedal located between the sheath, and the irrigation source and the suction source, the foot pedal comprising:
i) an actuation member;
ii) a resilient reservoir in communication with the irrigation line and the actuation member;
iii) a valve in communication with the suction line;

wherein movement of the actuation member causes the actuation member to evenly compress the resilient reservoir thus moving irrigation fluid from the resilient reservoir to the sheath, and
wherein during the movement of the actuation member, the valve is actuated so that suction begins to apply to the sheath after the irrigation fluid has began moving from the resilient reservoir to the sheath but before the irrigation fluid stops moving from the resilient reservoir to the sheath.

9. The system of claim 8 , wherein a control module comprises a controller in communication with the actuation member and the valve, and
wherein during the movement of the actuation member, the actuation member triggers a response from the controller, which initiates movement of the valve so that the valve opens and the suction from the suction line is applied to the sheath.

10. The system of claim 9 , wherein the foot pedal comprises a base,
wherein the resilient reservoir, the valve, and the controller are supported on the base, and
wherein the actuation member is connected to the base by a pivot, and during the movement of the actuation member, the actuation member pivotally moves relative to the base to evenly compress the resilient reservoir.

11. The system of claim 8 , wherein between the endoscope and the foot pedal, the suction line and the irrigation line are connected with a common fitting, and a common line extends between the common fitting and the endoscope.

12. The system of claim 8 , wherein the system is free of a peristaltic pump.
