Gastrointestinal decompression device

Abstract

The invention discloses a gastrointestinal decompression device. A purification cavity, a storage cavity, a battery cavity and a negative pressure cavity are formed in a box body, a storage battery and a control panel are arranged in the battery cavity, an air pump is arranged in the purification cavity, and an air pumping pipe is arranged at the bottom of the air pump. The bottom of the air pumping pipe is positioned in the negative pressure cavity, one end of the air pump is provided with a vent pipe, a first baffle and a second baffle are arranged in the purification cavity, one end of thefirst baffle is provided with a first activated carbon filtering layer, and a second activated carbon filtering layer is arranged at one end of the second baffle. A second ultraviolet lamp is arrangedin the purification cavity, a delta-sigma converter and a liquid level sensor are arranged on the two sides of the interior of the negative pressure cavity respectively, a display screen and a drainage pipe are arranged at one end of the box body, and one end of the drainage pipe is connected with the negative pressure cavity; a transparent cover is arranged on the side face of the drainage pipe,and a pinhole camera is arranged in the transparent cover. The device is convenient to carry and use, safe and capable of purifying extracted gas.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to a gastrointestinal decompression device. Background technique [0002] Gastrointestinal decompression is to use the principle of negative pressure and siphon to suck out the gas, liquid and food residue accumulated in the gastrointestinal tract, so as to reduce the pressure in the gastrointestinal tract, reduce the edema of the gastric mucosa, and improve the blood circulation of the gastrointestinal wall. It is beneficial to the limitation of inflammation, and it is a treatment method to promote wound healing and gastrointestinal function recovery. It is an important means for clinical treatment of gastrointestinal obstruction, retention, paralysis, perforation, and acute severe pancreatitis caused by various reasons. It is also an important treatment and nursing measure before and after gastrointestinal surgery. At present, the commonly used gastrointestinal decompressor has a si...

AI Technical Summary

Problems solved by technology

At present, the commonly used gastrointestinal decompressor has a single function and a relatively simple structure, including a drainage tube and a decompression bottle. The decompression bottle is a bellows structure. Press the decompression bottle before use to press out the internal air to form a negative pressure. , and then connected to the drainage tube, the negative pressure formed by the gastrointestinal decompressor structure of this structure is relatively large at the initial stage, and the drainage effect is not bad, but when the liquid or gas in the decompression bottle increases, the negative pressure inside It is getting smaller and smaller, and the drainage effect is getting worse and worse. For this reason, medical staff need to frequently repeat the steps of pressing-dumping liquid or gas-continuing pressing, which increases the burden on medical staff. At the same time, the existing gastrointestinal The decompressor cannot purify the extracted gas, which may cause disease infection and environmental pollution. At the same time, the existing gastrointestinal decompressor cannot carry out disinfection and sterilization of the drainage tube, which can easily cause secondary infection of patients
