Technical Field

[0002] The peristaltic pump (flushing pump, water delivery pump) used in digestive endoscope refers to a pump connected to the digestive endoscope during gastrointestinal endoscopy or treatment to deliver water and flush the gastrointestinal tract. Generally, a traditional peristaltic pump consists of a pump body, a catheter, a water bottle, a power supply, and a foot switch. One end of the catheter is connected to the water bottle, the middle of the catheter is connected to the pump body, and the other end is inserted into the endoscope interface. The foot switch controls the water delivery and stop. With the continuous development of endoscopic surgery, the single water injection function can no longer meet clinical needs, and two or three separate water pumps are cumbersome to operate. Each pump body needs to be equipped with a pump tube, a water bottle, etc., which is complicated and easy to make mistakes. When the pump head is installed, the pump tube is easy to loosen, thereby affecting the infusion efficiency. Therefore, we propose a new multi-pump head peristaltic pump for digestive endoscopy.
