Gastrointestinal tube with magnetic electrodes

Abstract

The invention relates to the technical field of medical equipment, in particular to a gastrointestinal tube with a magnetic electrode and suck-back prevention device. The gastrointestinal tube comprises a gastrointestinal tube body. The gastrointestinal tube body comprises a gastrointestinal tube front end and a gastrointestinal tube rear end. The gastrointestinal tube front end is provided with an air bag and a liquid outlet, wherein the gastrointestinal tube body is wrapped in the air bag. The gastrointestinal tube rear end is provided with an indication air bag which is connected with the air bag through a breather tube. The breather tube is partially buried in the wall of the gastrointestinal tube. The gastrointestinal tube further comprises a sealing sleeve which is connected with a choke plug. The chock plug is connected with the gastrointestinal tube front end. A high-strength magnet is arranged in the sealing sleeve. A probe is arranged in the high-strength magnet and penetrates through the choke plug. The probe is further connected with a wire which extends out of the gastrointestinal tube rear end. The gastrointestinal tube is simple in structure, capable of preventing liquid from flowing back and low in safety cost; the magnetic electrode is adopted as an intracavity negative electrode of the human body in cooperation with a positive electrode on the body surface, so that the electrodes are combined tight with the gastric wall or the intestinal wall. Accordingly, the problems existing in traditional gastric electrical signal acquisition are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a gastrointestinal tube with magnetic electrodes. Background technique [0002] Gastrointestinal nutrition is an important means of nutritional support. According to statistics, more than 60% of ICU patients have different degrees of gastrointestinal motility disorders. Due to factors such as delayed gastrointestinal emptying, cardiac insufficiency, and iatrogenic increased abdominal pressure, gastric juice often returns flow, aspiration into the airway, and then increase the length of hospital stay and mortality; design a gastrointestinal tube with an inflatable balloon, the balloon is located close to the cardia, can solve the gastric content reflux, aspiration into the airway, while using the balloon Inflation and deflation of the sac to stimulate the cardia can also solve the hiccup symptoms of some patients. [0003] In view of the different degrees of gastrointes...

Problems solved by technology

[0003] In view of the different degrees of gastrointestinal motility disorders in ICU patients, gastrointestinal motility drugs are often used clinically at present, and the curative effect is not good, which affects the implementation of enteral nutrition, and the timing of enteral nutrition implementation is significantly related to the patient's prognosis. Existing Gastrointestinal pacing is stimulated by placing electrodes on the surface of the gastrointestinal body, which is affected by the abdominal muscles and electrocardiographic activity. Some people also stimulate through a gastric tube with electrodes, but the close contact between the electrodes and the stomach wall cannot be guaranteed, and the effect is poor. The present invention adopts the magnetic electrode as the negative electrode in the human body cavity, cooperates with the positive electrode on the body surface, makes the electrode closely bond with the stomach wall or intestinal wall, solves the problem of traditional gastroelectric signal collection, and cooperates with the gastrointestinal electromagnetic instrument outside the body, it is expected to solve the problem of ICU patients' gastric Intestinal dysmotility
