A spin-washing double-chamber gastric lavage tube

Abstract

A spin-washing double-chamber gastric lavage tube, including a tube body whose front end can be inserted into the gastric cavity. The center of the tube body has a suction cavity for discharging the contents of the gastric cavity. Injection chamber, the liquid injection chamber is used for washing liquid to pass into the gastric cavity. The front end of the tube body is rotated to cooperate with a first swivel. The center hole of the first swivel coincides with the suction chamber. The first swivel has a The collecting tank distributed in the circumferential direction, the side of the collecting tank facing the tube body communicates with the liquid injection chamber, and the first swivel is provided with multiple spraying nozzles for the washing liquid to be sprayed out from the collecting tank and enter the gastric cavity. All the spray holes are evenly spaced along the circumference of the first swivel, and any spray hole is distributed along the axial direction oblique to the first swivel, and the inclination angle of all the spray holes is the same, so that the lotion is sprayed from the spray holes When it comes out, it drives the first rotating ring to rotate; the first rotating ring is also provided with a plurality of first paddles, and the first paddles are used to stir the washing liquid in the gastric cavity to form a swirling flow while the first rotating ring rotates. The invention is used to improve the cleaning effect of a single gastric lavage, reduce the number of times of gastric lavage, and further save treatment time.

Description

technical field [0001] The invention relates to the field of gastroenterology medical devices, in particular to a spin-washing double-chamber gastric lavage tube. Background technique [0002] Gastric lavage refers to pouring a certain composition of lotion into the gastric cavity, mixing the contents of the stomach and then drawing it out, and repeating this many times. Its purpose is to remove unabsorbed poison in the stomach or clean the gastric cavity, and it is clinically used for gastric surgery and preparation before examination. For acute poisoning, such as swallowing organic phosphorus, inorganic phosphorus, alkaloids, barbiturates, etc. within a short period of time, gastric lavage is an important rescue measure. In the process of gastric lavage, a double-lumen gastric tube (urinary catheter can be used in children) is usually inserted into the gastric cavity through the esophagus. The other lumen of the gastric tube injects lotion into the gastric cavity and dra...

Problems solved by technology

[0003] The gastric lavage method that can be realized by the above-mentioned conventional double-cavity gastric tube is simply feeding and extracting the lotion. A small part of the liquid not only leads to the waste of the lotion, but also requires the patient to go through multiple gastric lavages to achieve the effect, which brings great pain to the patient, and more importantly, the effect of cleaning the toxin on the stomach wall is poor, so that Toxins stay on the stomach wall for too long, delaying valuable treatment time
