Rotary washing type double-cavity lavage tube

Abstract

A rotary washing type double-cavity lavage tube comprises a tube body, the front end of the tube body can be inserted into a gastral cavity, a liquid extraction cavity for discharging contents in the gastral cavity is formed in the center of the tube body, an annular liquid injection cavity is formed in the portion, located on the periphery of the liquid extraction cavity, of the tube body, washing liquid is injected into the gastral cavity through the liquid injection cavity, the front end of the tube body is rotationally matched with a first rotating ring, ,the central hole of the first rotating ring correspondingly coincides with the liquid extraction cavity, a liquid collecting groove distributed in the circumferential direction of the first rotating ring is formed in the first rotating ring, the side, facing the tube body, of the liquid collecting groove is communicated with the liquid injection cavity, a plurality of spraying holes allowing washing liquid to be sprayed out of the liquid collecting groove and enter the gastral cavity are formed in the first rotating ring, all the spraying holes are evenly distributed in the circumferential direction of the first rotating ring at intervals any spraying hole is distributed in the axial direction inclined to the first rotating ring, and the inclination angles of all the spraying holes are the same, so that the first rotating ring is driven to rotate when washing liquid is sprayed out of the spraying holes; and a plurality of first paddles are further arranged on the first rotating ring and used for stirring washing liquid in the gastral cavity to form rotational flow along with rotation of the first rotating ring. The cleaning effect of single gastric lavage is improved, the gastric lavage frequency is reduced, and the treatment time is further saved.

Description

technical field [0001] The invention relates to the field of gastroenterology medical instruments, in particular to a rotary-wash double-lumen gastric lavage tube. Background technique [0002] Gastric lavage refers to pouring a certain composition of washing liquid into the gastric cavity, mixing the gastric contents and then extracting it, repeated many times. Its purpose is to remove the unabsorbed poison in the stomach or clean the stomach 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. in a short time, gastric lavage is an important rescue measure. In the process of gastric lavage, a double-lumen gastric tube (a urinary catheter can be used in children) is usually inserted into the gastric cavity through the esophagus, and the gastric contents are first extracted through one cavity of the double-lumen gastric tube, and...

AI Technical Summary

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
