Gastrointestinal pressure reducer with adjustable pressure

Abstract

The invention discloses a gastrointestinal pressure reducer with adjustable pressure. The gastrointestinal pressure reducer comprises an upper cover, a lower cover, a cylindrical barrel and a negativepressure suction spring, a sealed negative pressure suction cavity is formed among the upper cover, the lower cover and the cylindrical barrel; the gastrointestinal pressure reducer is characterizedin that a first ventilation seat and a second ventilation seat are arranged on the upper cover, ventilation holes are formed in the first ventilation seat and the second ventilation seat, the ventilation hole in the first ventilation seat is communicated with the gastrointestinal tract, and the ventilation hole in the second ventilation seat is connected with a pressure regulator used for regulating the maximum pressure in the negative pressure suction cavity. According to the gastrointestinal pressure reducer, the pressure in the negative pressure suction cavity can be limited within a set range, the negative pressure can be adjusted to be large to drain gastric contents of a patient, small negative pressure is adopted to drain intestinal contents of the patient, and the technical problems that intestinal mucosa damage and intestinal wall perforation are likely to be caused due to the fact that the same negative pressure is adopted in existing gastrointestinal drainage are solved.

Description

technical field [0001] The present invention relates to a pressure-adjustable gastrointestinal decompressor, more specifically, to a pressure-adjustable gastrointestinal decompressor which can select different negative pressures for gastric drainage and intestinal drainage. Background technique [0002] 1. Gastrointestinal decompression is widely used [0003] In recent years, there have been a lot of improvements in gastric tubes, such as: 1. Multifunctional three-way gastric tube and its usage method (application number 201510981006.6); 2. A gastric tube (application number 201510112560.0); 3. Blood oxygen saturation monitoring Functional multifunctional gastric tube (application number 201610134716.X), etc. All are different improvements of gastric tube function, and the invention of related gastrointestinal decompressor has not been investigated. [0004] Gastrointestinal decompression is the insertion of a gastric or gastrointestinal tube through the nasal cavity into...

AI Technical Summary

Problems solved by technology

[0005] 2. The effects of different diseases and different decompression methods on the gastrointestinal tract

[0007] 3. Insufficiency of current design, clinical value and necessity of design

There are some disadvantages in the existing negative pressure drainage device: 1. The gastrointestinal decompression method cannot be measured or controlled, and the patient’s situation cannot be accurately judged; 2. The pressure cannot be manually adjusted, the drainage speed is slow, and the suction force is small

Not convenient for clinical use
