Description

A barium meal radiography auxiliary device

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a barium meal radiography auxiliary device.

Background technique

Barium meal radiography, that is, gastrointestinal barium radiography, refers to an examination method that uses barium sulfate as a contrast agent to show whether there are lesions in the digestive tract under X-ray irradiation. Different from barium enema, barium meal contrast agent is taken orally, which can make a clearer radiological examination of the entire digestive tract, especially the upper digestive tract. The barium meal used for digestive tract examination is medicinal barium sulfate (ie, sulfate Barium suspension), because it is insoluble in water and lipids, it will not be absorbed by the gastrointestinal mucosa, so it is basically non-toxic to humans. Usually, before the examination, the nurse in the radiology department will mix the dry medical barium sulfate powder with water in proportion to make a suspension for the patient to take in portions, turn the body around, and cooperate with the doctor to complete the examination.

However, for elderly patients who are paralyzed, unable to stand or stand unsteadily, because it is inconvenient for the patient to stand, when performing barium meal angiography, it is necessary to manually assist the patient to take the barium meal and turn the body.

Because X-ray irradiation has a certain damage to the human body, using the above method will cause harm to the staff.

Contents of the invention

The purpose of the present invention is to provide a barium meal radiography auxiliary device, which fixes the patient through the wheelchair, the rotating mechanism rotates the wheelchair together with the patient, and the feeding mechanism assists the patient to take the barium meal without the need for staff to irradiate the barium meal. Assist the patient and avoid injury to the staff.
