Description
Technical Field
[0001] The utility model relates to the field of medical devices, and particularly relates to a gastrointestinal decompression device. Background Art
[0002] The gastrointestinal surgery department is a comprehensive department integrating clinical medicine, teaching, and scientific research. Its specialty covers most abdominal surgical diseases, including gastrointestinal diseases, anorectal diseases, acute abdomen, hernia and abdominal wall diseases, digestive tract tumors, and clinical nutritional support, etc. Gastrointestinal decompression is a commonly used nursing operation technique in gastrointestinal surgery. Its purpose is to drain the accumulated fluid in the stomach and the accumulated gas in the gastrointestinal tract, relieve abdominal distension and the tension of the suture site, and facilitate wound healing. It is a treatment method that uses the principle of negative pressure suction to suck out the accumulated gas and liquid in the gastrointestinal tract to reduce the pressure in the gastrointestinal tract, improve the blood circulation of the gastrointestinal wall, and is conducive to the limitation of inflammation, and drain the accumulated fluid in the stomach and the accumulated gas in the gastrointestinal tract.
[0003] In the prior art, the gastrointestinal fluid decompression device will suck out the liquid or gas in the gastrointestinal tract at the same time, resulting in a smaller compressible volume in the gastrointestinal fluid decompression device, and then the negative pressure generated inside becomes smaller, resulting in a slower and slower drainage rate for the patient. At this time, it is necessary to manually clamp the near end of the gastric tube for the patient frequently to discharge the drainage fluid inside the gastrointestinal fluid decompression device to ensure the negative pressure intensity inside the container. The operation is very cumbersome, and frequent operations will waste a lot of time and affect the patient's daily activities. And the existing gastrointestinal decompression device is easily squeezed by external forces during and after use, which will cause the situation of accumulated fluid backflow or spraying, thus affecting the safety of the device use.
