Abstract
An endoscope lens cleaning system for use in removing surgical debris from the objective lens of an endoscope has a sheath adapted to receive the endoscope, carrying a control switch and having an open distal end in fluid communication with a proximally mounted luer lock for removably engaging the distal luer connection of a tubing set. The tubing set is connected to and engaged with a peristaltic pump including a microprocessor or controller adapted to respond to actuation of the control switch and execute software including program steps for operation of the pump. The pump controller is programmed to execute a scrub cycle each time the clinician actuates the control switch mounted on the preferably disposable sheath. Scrub cycles are executed in a sequence of steps including a forward or outflow motion of the pump to dispense a first selected volume of irrigation fluid through the sheath and over the endoscope objective lens; a brief pause follows, to allow any residual fluid pressure to dissipate, and a reverse or inflow motion of the pump next withdraws or retracts any residual fluid droplets from the endoscope objective lens and into the sheath. The pump controller is programm…
