Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a negative pressure suction device for a digestive endoscope. Background Art
[0002] Digestive endoscopy negative pressure aspiration is a technology that uses negative pressure aspiration to help remove food residues, secretions and other foreign matter in the digestive tract such as the esophagus, stomach and duodenum during digestive endoscopy examination and treatment. Negative pressure aspiration can help doctors observe the situation in the digestive tract more clearly and improve the effectiveness of examination and treatment.
[0003] However, in the prior art, the existing suction device only performs suction by exhausting pressure, that is, the staff places the drainage tube at the position where the patient needs to excrete, and then exhausts the air pressure in the storage bottle through the suction and pressure device. However, once the suction and pressure device stops working, the remaining air in the storage bottle will enter the human body through the suction tube, and the residual excrement in the suction tube will also flow back due to the air, which reduces its practicality in actual use. Therefore, we provide a digestive endoscope negative pressure suction device. Utility Model Content
