Gastrointestinal fluid decompression device for gastrointestinal surgery

Abstract

The invention discloses a gastrointestinal fluid decompression device for gastrointestinal surgery, which includes a drainage tube and a storage barrel. The storage barrel includes a first barrel and a second barrel with a liquid level sensor inside. The liquid inlet corresponding to the liquid discharge port of the first barrel is provided with a solenoid valve on the liquid discharge port. The lower end of the first barrel is a groove, and the upper end of the second barrel is a raised structure that matches the groove. The upper end of the upper end is provided with an input pipe inserted into the air pump and controller inside the first barrel, and a clean air chamber and an ozone generator are arranged in turn on one side of the first barrel, and the inlet of the clean air chamber is connected with the output pipe of the air pump , the outlet of the clean air chamber is connected to the input end of the ozone generator, the output end of the ozone generator is connected to the air outlet device, the isolation cover is sleeved on the drainage tube, elastic strips are arranged on both sides of the isolation cover, and the second barrel There is a sterilization chamber on one side, and an ultraviolet lamp is arranged in the sterilization chamber. The invention has fast drainage speed and good decompression effect, and the gas is sterilized for post-treatment to prevent environmental pollution.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a gastrointestinal fluid decompression device for gastrointestinal surgery. Background technique [0002] In the clinical treatment of gastrointestinal surgery, once the patient has intraperitoneal fluid or increased intraperitoneal pressure, a gastrointestinal decompressor must be used to drain the gastrointestinal fluid or gas. Currently, the commonly used gastrointestinal decompression The structure of the device is relatively simple, 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 connect the drainage tube for use. This structure The negative pressure formed by the structure of the gastrointestinal decompressor is relatively large at the beginning, and the drainage effect is not bad, but when the liquid ...

[0002] In the clinical treatment of gastrointestinal surgery, once the patient has intraperitoneal fluid or increased intraperitoneal pressure, a gastrointestinal decompressor must be used to drain the gastrointestinal fluid or gas. Currently, the commonly used gastrointestinal decompression The structure of the device is relatively simple, 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 connect the drainage tube for use. This structure The negative pressure formed by the structure of the gastrointestinal decompressor is relatively large at the beginning, and the drainage effect is not bad, but when the liquid or gas in the decompression bottle increases, the internal negative pressure becomes smaller and smaller, and the drainage effect becomes worse For this reason, the medical staff need to frequently repeat the steps of pressing-dumping liquid or gas-continuing pressing, which increases the burden on the medical staff, and at the same time, the data of this structure is easy to be taken out of the patient's stomach when pumping the internal pressure. Breath, if the patient’s breath has virus, it is easy to inhale the virus into the decompression bottle, and it is easy to pollute the environment when it is removed later
