Abstract: An arthroscopy pump tubing set for delivering a sterile fluid under pressure to a patient undergoing arthroscopic surgery. The tubing set is installed on a peristaltic arthroscopy pump. Fluid is delivered under pressure from fluid bags to a patient, through supply tubing of the tubing set, to achieve better visualization of the operative site. A chamber with a fixed volume is attached to the fluid supply tubing, and a collapsible bladder is contained within the chamber. The collapsible bladder has an open end connected with tubing to a pressure transducer inside the arthroscopy pump. Once activated, the pump begins to introduce sterile fluid from the bags, through the tubing, and into the patient. As pressure builds within the operative site, fluid enters the chamber, and air in the chamber is compressed. The compressed air in the chamber compresses the bladder. Air pressure in the bladder is experienced by the pressure transducer inside the arthroscopy pump.
