Embodiment Construction

[0016] As shown in the figure, this embodiment includes a transparent hose 1 and two thin tubes fixed outside the hose 1, which can be bonded respectively or made in one piece. The rear end of the hose 1 is sheathed with a sleeve holder 18 for squeezing and fixing the outer wall of the rear port of the hose 1 , and a sleeve supporter 12 is inserted into the rear port of the hose 1 . The pipe socket supporter 12 is a tubular structure, and its outer wall is a tapered surface with a diameter at the rear end greater than the inner diameter of the rear end of the hose 1 and a diameter at the front end smaller than the inner diameter of the rear end of the hose 1 . The two thin tubes on the outside of the hose 1 are the negative pressure suction clamp tube 2 and the water injection and air injection tube 4 respectively, and the rear ends thereof are all three-way structures. Wherein, one end of the other two ends of the negative pressure suction clamp channel pipe 2 is the clamp ch...

Abstract

The invention relates to the technical field of medical instruments, in particular to a disposable three-cavity gastroscope and enteroscope sleeve which can prevent cross infection during gastroscopy. The technical scheme includes that firstly, a negative pressure suction forceps channel tube and a water and air injecting pipe are fixed on the outer side of a flexible pipe, thereby an independent water and air pipeline system, an independent negative pressure suction and forceps channel system, a gastroscope air and water eduction control system and a negative pressure suction and forceps channel eduction control system are formed, the complete disposable three-cavity gastroscope and enteroscope sleeve is formed, and gastroscope or enteroscope can be thoroughly isolated from a gastral cavity or an intestinal tract during gastroscopy or enteroscopy. Accordingly, defects of prior built-in pipelines of the gastroscope and the enteroscope are overcome, sterility tests of the gastroscope and the enteroscope are achieved, and the cross infection is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable three-chamber stomach and colonoscope sleeve which can prevent cross-infection during gastroenteroscopy. Background technique [0002] Clinically, there are often problems affecting the clarity and accuracy of images captured by the CCD camera due to food residues and a large amount of gastric juice secretion. Though common gastroscope cover has solved these problems, still there are some defectives. The gastroscope is originally equipped with a built-in suction pipeline, clamp channel, suction control switch, water injection and gas injection pipeline, and water and gas injection switch. All the pipelines are connected with the gastric cavity, and the previous patient and the next patient under examination are likely to cause cross infection. The same goes for a bowel check. Contents of the invention [0003] The object of the present invention is to dis...
