Systems and methods for peristaltic endoscope cleaning
The present disclosure is directed to endoscope cleaning systems and methods. The endoscope cleaning system can include a pump housing that houses a peristaltic pump, an endoscope sheath fluidly connected to the pump housing, and a pump control communicatively coupled to the peristaltic pump. Upon activation of the pump control, the peristaltic pump can supply fluid to the endoscope sheath for cleaning an endoscope. Upon deactivation of the pump control, the peristaltic pump can remove residual fluid from the endoscope.
1. An endoscope cleaning system comprising:
a pump housing comprising a fluid inlet, a fluid outlet, and a peristaltic pump configured to displace fluid from the fluid inlet to the fluid outlet;
an endoscope sheath fluidly connected to the fluid outlet of the pump housing, wherein the endoscope sheath is configured to receive an endoscope; and
a microcontroller configured to execute:
upon activation of the peristaltic pump, the peristaltic pump displaces fluid from the fluid inlet to the fluid outlet at a first speed for a first period of time;
while the peristaltic pump is still activated and upon termination of the first period of time, the peristaltic pump displaces fluid from the fluid inlet to the fluid outlet at a second speed, wherein the second speed is less than the first speed;
upon deactivation of the peristaltic pump, the peristaltic pump displaces fluid from the fluid outlet to the fluid inlet at a third speed for a second period of time; and
while the peristaltic pump is deactivated and upon termination of the second period of time, the peristaltic pump displaces fluid from the fluid outlet to the fluid inlet at a fourth speed for a third period of time, wherein the fourth speed is less than the third speed.
2. The cleaning system of claim 1 , wherein the peristaltic pump comprises a plurality of peristaltic rollers and a motor to drive the peristaltic rollers.
3. The cleaning system of claim 2 , wherein the peristaltic pump comprises a battery assembly to power the motor.
4. The cleaning system of claim 1 , wherein the endoscope sheath and the fluid outlet of the pump housing are fluidly connected by tubing.
5. The cleaning system of claim 4 , wherein the tubing is fluidly connected to a proximal end of the endoscope sheath.
6. The cleaning system of claim 1 , wherein the endoscope sheath is configured to supply fluid to a distal end of an endoscope.
7. The cleaning system of claim 1 , wherein the fluid inlet comprises a spike on a top surface of the pump housing.
8. The cleaning system of claim 7 , wherein the spike is a hollow, tapered spike.
9. The cleaning system of claim 8 , wherein the hollow, tapered spike is configured to be inserted into a fluid source.
10. The cleaning system of claim 9 , wherein the fluid source is a sterile irrigation bag.
11. The cleaning system of claim 1 , wherein the fluid outlet is perpendicular to the fluid inlet.
12. The cleaning system of claim 1 , wherein the microcontroller is configured to execute: while the peristaltic pump is deactivated and upon termination of the third period of time, the peristaltic pump shuts off.
13. A method of cleaning an endoscope, comprising:
providing the endoscope cleaning system of claim 1 ;
activating a pump control;
upon activation of the pump control, displacing, via the peristaltic pump, fluid from the fluid inlet to the fluid outlet of the pump housing;
deactivating the pump control; and
upon deactivation of the pump control, displacing, via the peristaltic pump, fluid from the fluid outlet to the fluid inlet of the pump housing.
14. The method of claim 13 , wherein upon activation of the pump control, the peristaltic pump displaces fluid from the fluid inlet to the fluid outlet at the first speed for the first period of time.
15. The method of claim 14 , wherein while the pump control is activated and upon termination of the first period of time, the peristaltic pump displaces fluid from the fluid inlet to the fluid outlet at the second speed, wherein the second speed is less than the first speed.
16. The method of claim 13 , wherein upon deactivation of the pump control, the peristaltic pump displaces fluid from the fluid outlet to the fluid inlet at the third speed for the second period of time.
17. The method of claim 16 , wherein while the pump control is deactivated and upon termination of the second period of time, the peristaltic pump displaces fluid from the fluid outlet to the fluid inlet at the fourth speed, wherein the fourth speed is less than the third speed.
18. The method of claim 17 , wherein the peristaltic pump displaces fluid from the fluid outlet to the fluid inlet at the fourth speed for the third period of time.
19. The method of claim 18 , wherein upon termination of the third period of time, the peristaltic pump shuts off.
20. The method of claim 13 , further comprising inserting an endoscope into the endoscope sheath.
21. The method of claim 13 , further comprising inserting the fluid inlet of the pump housing into a fluid source.
22. The method of claim 21 , wherein the fluid inlet is a hollow, tapered spike.
23. The method of claim 22 , wherein the fluid source is a sterile irrigation bag.
24. The method of claim 13 , wherein the pump control is communicatively coupled to the peristaltic pump.
25. The method of claim 24 , wherein the pump control is wirelessly communicatively coupled to the peristaltic pump.
26. The method of claim 13 , wherein while the pump control is activated, fluid is supplied from the endoscope sheath to a distal end of an endoscope.
27. The method of claim 13 , wherein while the pump control is deactivated, fluid is removed from the distal end of the endoscope to the endoscope sheath.
