Indwell dilator for treating achalasia of cricophyaryngeus muscles

Abstract

The invention discloses an indwell dilator for treating achalasia of cricophyaryngeus muscles. The indwell dilator comprises an expandable sacculus and a gastric tube, wherein the expandable sacculusis mounted on the gastric tube in a sleeving manner; a first through hole and a second through hole are separately formed in the left side and the right side of the inner side wall of the expandable sacculus; the two through holes are formed in the near end of the gastric tube through an opening of a connecting tube arranged in the gastric tube wall; a pressure monitoring mechanism is mounted above the first through hole; and an injection mechanism is mounted above the second through hole. The indwell dilator for treating the achalasia of cricophyaryngeus muscles disclosed by the invention solves the following problems: in a conventional treatment course of the achalasia of cricophyaryngeus muscles, repeated draw-out and insertion of the gastric tube are required when expansion treatment is carried out by using the expandable sacculus every time, and thus pains and economic expenses of patients are increased; injection of saline water amount required by expansion of the expandable sacculus is evaluated in accordance with feel of a patient and an operator, and therefore, the injection evaluation is not objective, if the saline water amount is injected excessively, esophageal mucosais possibly hurt, otherwise, less amount of saline water is injected, a treatment effect cannot be achieved; and the insertion depth of the expandable tube is difficultly controlled, the pain of the patient is increased if the expandable tube is inserted too deeply, otherwise the treatment effect cannot be achieved if the expandable tube is inserted too shallowly.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an indwelling expansion device for treating cricopharyngeal muscle achalasia. Background technique [0002] Dysphagia is a common complication of neurological diseases such as stroke, and cricopharyngeal muscle spasm or achalasia is an important mechanism leading to dysphagia. Inflatable balloon dilation is an effective treatment for cricopharyngeal muscle achalasia, but traditional The expandable balloon dilation method is to pull out the patient's indwelling gastric tube first, then insert a silicone tube or urinary catheter with an expandable balloon into the patient's throat, expand the expandable balloon with saline, and then repeatedly pull out the expansion tube. After the treatment is over, the gastric tube needs to be reinserted to assist the patient to eat through the gastric tube. [0003] There are certain defects in this treatment method. Each ti...

AI Technical Summary

Problems solved by technology

[0003] There are certain defects in this treatment method. Each time the expandable balloon dilation treatment needs to repeatedly pull out and insert the gastric tube, which increases the patient's pain and economic costs, and the amount of saline injected into the expandable balloon expands according to the needs of the patient and the operator. It is not objective to evaluate by feeling. If too much saline is injected, it may damage the esophageal mucosa. If too little is injected, it will not achieve therapeutic effect, and it is difficult to grasp the depth of dilation tube insertion. Too deep insertion will increase the pain of the patient, and too shallow insertion , no therapeutic effect

At the same time, and the time of expansion treatment is short, the expansion effect is poor
