Ileus dredging device

Abstract

The invention discloses an ileus dredging device which comprises a conduit, wherein a side hole is formed in the front end pipe wall of the conduit, an outer guide hole is formed in the rear end of the conduit, a pneumatic guide head is disposed on the front end of the conduit body, the pneumatic guide head comprises a pneumatic telescopic body and an elastic balloon which are connected integrally, and the elastic balloon is located on the front end of the pneumatic telescopic body; and the pneumatic telescopic body and the elastic balloon are connected to a telescopic body pipe and a balloonpipe respectively, the telescopic body pipe and the balloon pipe penetrate out from the tail part of the conduit, a telescopic body pipe joint and a balloon pipe joint used for air inflation and air deflation are disposed at the tail end of the telescopic body pipe and the tail end of the balloon pipe respectively, and the balloon pipe is an X-ray development pipe. The ileus dredging device is applied to depressurization, discharge of pneumatosis and hydrops and liquid medicine injection for an ileus patient. During use, when the conduct cannot be advanced normally due to obstruction obstacles, the pneumatic guide head can be operated to drag the conduit to advance and pass through the obstacles step by step to reach a drainage part. The flexible telescopic body pipe and the soft balloon pipe can look for clearance automatically when being inflated to extend, the passing capability is strong, the intestinal wall is not damaged, and operations are convenient, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of digestive tract intubation equipment, and in particular relates to a device for pressure relief, drainage and liquid medicine injection of intestinal obstruction. Background technique [0002] Clinically, intestinal contents cannot function normally and pass smoothly through the intestinal tract, which is collectively referred to as intestinal obstruction. Once intestinal obstruction occurs, the intestinal flora is often accompanied by abnormal changes. If the intestinal tract is not cleared to remove the contents in time, the intestinal secretion will be abnormally hyperactive, the intestinal contents will further increase, and the intestinal flora will become more imbalanced, forming a vicious circle. Severe cases can lead to cessation of ileal absorption, intestinal wall ischemia, and strong local intestinal peristalsis, resulting in intestinal damage and necrosis. For patients with intestinal obstruc...

Problems solved by technology

There are several problems in this kind of catheter. The first is that when the guide wire is inserted into the catheter, the guide wire is easy to protrude from the side hole of the catheter, stabs the intestinal wall, and even causes perforation of the digestive tract; The front end of the guide wire is likely to cause damage to the duodenal bulb or its vicinity; third, due to the friction between the guide wire and the inner cavity of the catheter, especially when the catheter is curved in the patient's body, the frictional resistance increases, making it difficult to insert and insert the guide wire , inconvenient to operate
