High-sealing stomach tube drainage device for gastroenterology department

Abstract

The invention discloses a high-sealing stomach tube drainage device for the gastroenterology department, and relates to the technical field of medical instruments, the high-sealing stomach tube drainage device comprises a portable box, the bottom of the inner wall of the portable box is fixedly provided with a stress mechanism, the top of the stress mechanism is in lap joint with a negative pressure device, one end of the negative pressure device is fixedly connected with a metering bottle, the metering bottle is communicated with the negative pressure device through a connecting pipe, and a flow guide pipe is arranged in the portable box in a lap joint mode. In the using process, after one end of the flow guide pipe is connected to the surface of an output pipe in a sleeving mode through a user, a bidirectional threaded rod is rotated, so that two threaded through holes drive two clamping and pressing plates to move in the opposite directions at equal intervals; in the moving process of the clamping and pressing plates, due to the existence of limiting arms, the clamping and pressing plates cannot rotate and only can transversely move in parallel, so that grooves formed in surfaces of clamping and pressing plates are embedded in the surface of the flow guide pipe, the flow guide pipe is reinforced by means of pressure generated by the two clamping and pressing plates, and the situation that flow guide pipe falls off in the operation process of the user and the equipment sealing performance is affected can be prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a highly sealed gastric tube drainage device for gastroenterology. Background technique [0002] After clinical surgery in the hospital, it is often necessary to decompress the stomach for patients with abnormal gastrointestinal symptoms to reduce abdominal distension and lead to the accumulation of fluid and gas in the gastrointestinal tract, so as to facilitate the recovery of the gastrointestinal function of the patient. However, some existing gastric tube negative pressure drainage devices on the market use detachable hoses for drainage, but because of the convenience of hose removal for storage and cleaning, there are some problems that have not been solved well during use: 1. Some existing gastric tube drainage devices on the market only rely on the sleeve structure to fix the hose and the negative pressure device, resulting in poor sealing and stability, and the ho...
