Gastrointestinal administration device for digestive department

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a gastroenterology department gastrointestinal drug delivery device which comprises a catheter for delivering liquid medicine, the catheter is a hose, and a drug supply mechanism, a traction mechanism and a drug spraying end seat are arranged on the catheter; the medicine supply mechanism comprises a liquid medicine bag arranged at the top of the catheter, the liquid medicine bag is connected with the open end of the catheter through a catheter connector at the bottom of the liquid medicine bag, and a pressurization connecting pipe connected with an external pressure device is installed at the top of the liquid medicine bag; the traction mechanism is composed of a pipe plug seat and a guide seat in a matched mode, the upper portion and the lower portion of the catheter are guided and limited respectively, the traction mechanism can be matched with the air bag mechanism to achieve branch fixing in the throat and the body, the problem that the catheter is affected and prone to deviation is solved, and the stability of the catheter in the liquid medicine conveying and spraying process is guaranteed. A filter screen is arranged in the pesticide spraying end seat, particles which are not easy to absorb are prevented from being mixed in the pesticide liquid, the pesticide liquid is filtered, subsequent spraying of the pesticide liquid is facilitated, and through holes formed in the pesticide spraying end seat 5 can be prevented from being blocked.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a gastroenterology drug delivery device. Background technique [0002] Gastroenterology, including Gastroenterology and Gastrointestinal Surgery, is a clinical department set up by hospitals at all levels to diagnose and treat diseases of the digestive system. The diseases to be treated include diseases of the esophagus, stomach, intestines, liver, gallbladder, pancreas, peritoneum, mesentery, omentum and other organs. Among them, the stomach and intestines are in the patient's body, and the patient's body is difficult to use by conventional injection and medication methods. It acts directly on the stomach and intestines, resulting in low efficacy and requires an applicator to assist in administration. [0003] The existing technology has the following problems: [0004] 1. When the drug is delivered to the patient's stomach, it needs the assistance of a catheter. When the exis...

AI Technical Summary

Problems solved by technology

[0004] 1. Catheter assistance is needed to deliver the drug to the patient's stomach. The existing catheter is pushed to the stomach part when it is inserted, which is hindered by the patient's instinctive swallowing. The catheter will protrude from the throat, resulting in cumbersome steps to insert the catheter into the stomach. And the damage to the patient's larynx is relatively large;

[0005] 2. When administering medicine, the catheter lacks a limit in the gastrointestinal section, which is prone to shaking and deviation, resulting in the inability of the front-end liquid spray end seat to accurately apply the drug to the stomach, and even the deviation of the liquid spray end seat to stab the gastrointestinal area ,Flawed
