Problems solved by technology

At this time, since the external force is not concentrated on the indwelling part in the body, and there will be an operation to increase the external force, the insertion operation into the body becomes more and more difficult.
In addition, the existing catheter for fistula has the problem that if the indwelling part in the body is pushed through the sealing device or the hollow rod, the sealing device or the hollow rod will break at the contact part and penetrate the front end of the indwelling part in the body. , the indwelling part in the body cannot be inserted into the body
Moreover, the existing catheter for fistula has the problem that the operation of pushing and extending the indwelling part 102 of the catheter 100 and the operation of inserting the catheter 100 into the stomach must be performed simultaneously. , must have operational ability and operational skills

Abstract

Disclosed is a catheter tool for fistula with excellent operability including a catheter and a sealing device. The catheter has a flexible tube and an indwelling part in the body. The flexible tube extends along the wall of the fistula hole. A nutrition passage is provided inside the fistula hole to introduce nutrition or medicinal liquid into the stomach. The indwelling part in the body is attached to the soft tube. The protruding shape of the front end of the tube is a non-balloon indwelling part in the stomach in the body buried state while shrinking from the protruding state due to the external force caused by the sealing device. The sealing device is pulled out A sealing device that may be matched to the aforementioned catheter, which has a guide wire passage and an operation part, the guide wire passage is used to insert the guide wire attached from the front end to the middle of the guide wire, and the operation part is used to insert the guide wire attached to the rear end of the guide wire passage. The indwelling part in the body transmits the external force, and the rear end part of the guide wire channel and the operation part are arranged in a separated state.

Description

technical field [0001] The present invention relates to a catheter device for a fistula with excellent operability, which is used in percutaneous endoscopic gastrostomy for the purpose of supplying nutrients or medicines. Background technique [0002] As a method of administration to patients who cannot take nutrition orally, there are generally intravenous nutrition administration, gastric tube nutrition administration by inserting a nutrition tube through the nose into the stomach or intestines, and feeding from a gastric fistula. Three administration methods for enteral nutritional administration. In recent years, enteral nutrition management through percutaneous endoscopic gastrostomy (PEG: Percutaneous Endoscopic Gastrostomy) has been performed more and more frequently due to the development of enteral nutrition and its administration method. Compared with surgical laparotomy gastrostomy, PEG is less traumatic and can greatly reduce medical expenses because it uses a s...
