Cardia anti-tearing decompression device

Abstract

The utility model relates to the technical field of medical instruments, in particular to a cardia anti-tearing decompression device. The cardia anti-tearing decompression device comprises a storage tube and a decompression tube, wherein the storage tube and the decompression tube are straight tubes which are through up and down, the inner diameter of the storage tube is larger than the outer diameter of the decompression tube, so that the decompression tube can be stored in a tube cavity of the storage tube, a first taper tube is fixed to the upper end of the decompression tube, and a secondtaper tube is fixed to the lower end of the decompression tube; and the first taper tube and the second taper tube are elastic soft taper tubes which are through up and down, a narrow end tube openingof the first taper tube is in butt joint with an upper end tube opening of the decompression tube, a narrow end tube opening of the second taper tube is in butt joint with a lower end tube opening ofthe decompression tube, and the first taper tube and the second taper tube can be retracted into a tube cavity of the storage tube after radial contraction. The device provided by the invention is matched with an esophageal endoscope for use.

Description

technical field [0001] The invention relates to the technology of medical instruments, in particular to the technology of a cardia anti-tear decompression device. Background technique [0002] In the process of esophageal endoscopic treatment, due to the need to clearly expose the surgical field of view, the patient’s esophagus must be frequently inflated during the operation, which may easily lead to tearing and bleeding of the cardia and gastric body mucosa in the patient due to excessive gas in the stomach . [0003] In order to avoid the above risks, during esophageal endoscopy, the gastroscope must be inserted into the stomach to suck out the gas at regular intervals, and then the gastroscope will be moved back to the surgical site (esophagus). This operation must be repeated many times during the operation , which brings great inconvenience to the operation and interferes with the operation. Contents of the invention [0004] Aiming at the above-mentioned defects i...
