Description

Intestinal obstruction dredging device

Technical Field

The invention belongs to the technical field of digestive tract intubation tools, and particularly relates to a device for ileus pressure relief, bowel movement and liquid medicine injection.

Background

Clinically, intestinal contents do not function normally and pass smoothly through the intestine, and intestinal obstruction is commonly referred to as intestinal obstruction. Once intestinal obstruction occurs, flora abnormal changes often occur in the intestinal tract, if the intestinal tract is not dredged in time to remove contents, intestinal secretion can be abnormally intensified, the intestinal contents are further increased, intestinal flora is more disordered to form vicious circle, the absorption function of the ileum can be stopped seriously, the intestinal canal wall is ischemic, and intestinal canal damage and necrosis are caused by local strong peristalsis of the intestine. For patients with intestinal obstruction, the intestinal obstruction catheter is inserted into the intestine of the patient to suck, decompress and remove the stem of gas and effusion at the intestinal obstruction part, which is not only a preferred scheme for non-surgical treatment of intestinal obstruction, but also an important auxiliary means for surgical treatment. When the intubate, because intestinal obstruction patient's intestines pipe generally can take place the swelling, the intestinal is narrow, and for the insertion of pipe, the mediation pipe that has current generally used generally is equipped with the seal wire, and the intestinal obstruction pipe inserts patient's intestinal obstruction position under the guide of seal wire. The catheter has several problems, firstly, when the guide wire is inserted into the catheter, the guide wire is easy to extend out from the side hole of the catheter, and the intestinal wall is punctured, even the digestive tract is punctured; secondly, for the intestinal obstruction catheter with an opening at the front end, the front end of the guide wire is easy to damage the duodenal bulb or the part nearby; thirdly, because the guide wire and the inner cavity of the catheter have certain friction, especially when the catheter is in a bending shape in the body of a patient, the friction resistance is increased, the guide wire is difficult to pull and insert, and the operation is inconvenient.
