Systems and methods for peristaltic endoscope cleaning

Abstract

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.

         9 . The system of  claim 2 , wherein the fluid outlet is perpendicular to the fluid inlet. 
     
     
         10 . The system of  claim 2 , wherein the peristaltic rollers comprise cylindrical peristaltic rollers. 
     
     
         11 . The system of  claim 2 , further comprising an endoscope sheath fluidly connected to the fluid outlet of the pump housing, 
     
     
         12 . The system of  claim 11 , wherein the endoscope sheath is configured to receive an endoscope. 
     
     
         13 . The system of  claim 12 , wherein the endoscope sheath and the fluid outlet of the pump housing are fluidly connected by tubing. 
     
     
         14 . The system of  claim 13 , wherein the tubing is fluidly connected to a proximal end of the endoscope sheath. 
     
     
         15 . The system of  claim 14 , wherein the endoscope sheath is configured to supply fluid to a distal end of an endoscope. 
     
     
         16 . The system of  claim 15 , further comprising a pump control communicatively coupled to the peristaltic pump, wherein the pump control is configured to control the peristaltic pump. 
     
     
         17 . The system of  claim 16 , wherein the pump control is attached to a distal end of the tubing. 
     
     
         18 . The system of  claim 17 , wherein the pump control is attached to the tubing by the proximal end of the endoscope sheath. 
     
     
         19 . The system of  claim 18 , wherein the pump control is wireless communicatively coupled to the peristaltic pump. 
     
     
         20 . The system of  claim 16 , wherein the pump control is a hand-controlled switch or a foot-controlled switch.
