Description

Intestinal tract expanding device Technical Field The utility model relates to a medical video auxiliary device, in particular to an intestinal dilation device which is suitable for assisting in CT, magnetic resonance and X-ray examination of intestinal lesions of patients. Background When a doctor is in medical treatment on a patient with intestinal lesions, CT, magnetic resonance or X-ray examination is often needed, so that the etiology is checked, the medical effect is improved, and the doctor fills liquid or gas into the intestinal tract of the patient through the anus when the doctor is in the examination. At present, no matter filling liquid or gas, the shape of the cannula is original due to the unchanged diameter of the cannula, discomfort or leakage phenomenon can be generated when the cannula enters the anus, and the traditional intestinal canal expansion whole set of device is disposable, so that resource waste is caused. Disclosure of utility model The utility model relates to an improvement of a traditional intestinal dilatation device when CT, magnetic resonance or X-ray examination is carried out on an intestinal patient in a hospital, which is mainly characterized in that an intubation head is additionally arranged at the head end of an intestinal gas transmission pipe, the top end of the intubation head is arranged in a semicircular shape, a gas outlet hole of the intubation head is arranged on the side wall of the top end of the intubation head, the outer wall of the tail end of the intubation head is arranged in a horn shape, the discomfort of the patient can be reduced when the circular intubation head of the intestinal dilatation device is inserted into anorectal, the leakage of the horn-shaped outer wall of the tail end of the intubation can be prevented, the diameter and the length of the intubation can be made into different types according to the body weight of different patients, the rest parts of the intestinal dilatation device can be reused except the intubation head for one-time use, and the resource waste is reduced. The elastic balloon is characterized in that the top end of the intubation head is provided with the semicircular head, the side wall of the top end part of the intubation head is provided with the air hole, the air hole is communicated with the air delivery channel of the intubation head, the outer part of the tail end of the intubation head is provided with the trumpet-shaped outer wall, the air delivery channel of the intubation head is communicated with the air outlet end of the air outlet one-way valve, the air inlet end of the air outlet one-way valve is communicated with one end of the air delivery pipe, the other end of the air delivery pipe is communicated with the air outlet of the elastic balloon, the air inlet of the elastic balloon is communicated with one end of the air inlet pipe, the other end of the air inlet pipe is communicated with the air inlet one-way valve, the elastic balloon is deformed when pressure is applied to the elastic balloon, the air inlet one-way valve is automatically closed, the air in the elastic balloon is discharged from the air hole to enter the intestinal tract through the air delivery pipe, the air outlet one-way valve and the intubation head, when the elastic balloon loses pressure, the air is automatically closed, the air enters the elastic balloon through the air inlet one-way valve and the air inlet one-way valve, the air inlet is repeatedly pressurized to the elastic balloon, and the effect of the intestinal tract is achieved.
