Description

Head fixing device for gastroscopy

Technical Field

The utility model relates to a gastroenterology medical technology field, concretely relates to gastroscopy head fixing device.

Background

In gastroscopy, the patient is generally in the left lateral decubitus position facing the examining physician. The patient all has the fear psychology to the gastroscope inspection, lies in the inspection bed, and is whole body nervous, and the body is stiff, when the doctor inserts the gastroscope to the patient mouth, the patient head can moderate degree be faced back and guarantee to advance the mirror unobstructed, nevertheless advance mirror in-process patient often because fear leads to the head to face back the range too big, can lead to the tongue tenesmus like this, and the esophagus mouth is pushed down to the root of the tongue portion, and the air flue is opened, and the easy mistake intake pipe of gastroscope arouses that the patient acutely coughs, and the patient is very painful. In addition, the gastroscope enters the esophagus and needs the patient to swallow, and the posterior root of the tongue blocks the esophagus opening, so that the gastroscope is difficult to enter the esophagus, and the mirror moves repeatedly at the throat part, thereby causing the patient to have strong nausea reaction. Even if the gastroscope enters the esophagus, the patient feels nausea and fear due to the continuous rotation of the mirror in the stomach, the head of the patient also can involuntarily lean backwards, the tongue falls to narrow the mouth of the esophagus, the operator feels difficulty in advancing and retreating the mirror, the patient can vomit seriously and continuously, and the patient can find that the throat is congested and blooded after the examination. Therefore, in order to conveniently carry out gastroscopy, the head of a patient needs to be fixed in position during endoscope insertion, and the phenomenon that the endoscope insertion is inconvenient due to overlarge backward tilting amplitude cannot occur.
