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

A catheter kit for a burrow having a catheter and an obturator and excellent in operability. The catheter comprises a tube having, inside, a nutrient passage leading nutrition or chemicals from the outside of a body to the inside of a stomach and extending along the wall surface of the burrow and a non-balloon type endodwelling member fitted to the tip part of the tube, normally placed in an expanded state and reduced in diameter less than that in the expanded state when an external force acts thereon by the obturator, and indwelled in the stomach in a buried state in a living body. The obturator comprises a guide wire passage detachably engaged with the catheter and allowing a guide wire installed in the obturator ranging from the tip to the midway thereof to be inserted therein and an operation part for transmitting the external force to the endodwelling member fitted to the rear end thereof. The rear end part of the guide wire passage and the operation part are arranged in a separated state.

Description

[0001] This application is a divisional application of an invention patent application that entered the Chinese national phase with the international application date of April 26, 2004, and whose international application number is PCT / JP2004 / 005976. The date is April 26, 2004, the application number is 200480011112.1, and the title of the invention is "catheter device for fistula hole". technical field [0002] 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 [0003] 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 admi...
