Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a simple digestive endoscope flushing device. Background Art

[0002] Digestive endoscopy is an important detection method for diagnosing digestive system diseases. However, due to improper use of defoaming agents, poor intestinal cleansing, and bleeding in the digestive tract, the digestive tract cavity needs to be flushed to expose the field of vision, which is beneficial for doctors to observe and diagnose. However, defoaming agents and purified water are needed during the inspection and cleaning process. The defoaming agents and purified water need to be stored in two water tanks, which causes certain inconveniences during use.

[0003] Moreover, due to the fact that gastroscopes used for simple examinations do not have a secondary water supply function and the high price of water pumps, most hospitals still use syringes to draw purified water or purified water containing simethicone and insert it into the biopsy cap for flushing. Gastric contents, feces or blood may reflux, and the syringe must be replaced every time it is flushed, which is costly. If the syringe is not replaced in time, cross infection may occur, leading to the spread of disease. In addition, the existing flushing method is not convenient for aspirating purified water or defoaming agents.

[0004] Therefore, we proposed a simple digestive endoscope flushing device. Utility Model Content

[0023] The utility model provides a simple digestive endoscope flushing device, in which a water tank 1 is divided by a partition plate 14 when in use, which can facilitate the storage of purified water or defoaming agent, and the outflow can be controlled by the three-way pipe 3 to meet the flushing needs in different situations. The peristaltic water pump 7 can be conveniently disassembled for disinfection of the water pipe, and the one-way water stop valve 8 can prevent the liquid in the digestive tract from flowing back through the biopsy channel. The disposable flushing conversion joint 9 that can be installed on the biopsy cap has a low replacement frequency, which can reduce costs while avoiding cross infection and protect patients.

[0024] In one embodiment provided by the present invention, a partition plate 14 is provided in the middle of the water tank 1, a water suction hose 15 is provided on the outer surface of the lower end of the connecting seat 4, guide rails 16 are provided on the inner surfaces of both sides of the water tank 1, a lifting plate 17 is provided in the middle of the guide rail 16, a slider 18 is provided between the lifting plate 17 and the guide rail 16, a limiting spring 19 is provided between the slider 18 and the guide rail 16, and a sealing strip 20 is provided on the outer wall of the lifting plate 17.
