Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-4, a direction-adjustable digestive tract catheter pylorus passing device comprises a first end head 1 and a first end plug 2, wherein a channel is arranged inside the first end plug 2, a first connecting pipe 3 is arranged inside the channel, the first end head 1 is bonded with one end of the first connecting pipe 3, a cavity channel is arranged inside the first end head 1, one end of the first connecting pipe 3, which is far away from the first end head 1, is connected with a spiral pipe 4, and the other end of the spiral pipe 4 is fixedly connected with a body pipe 6 through a second connecting pipe 5;

the utility model discloses a spiral pipe 4, the outside is installed in spiral pipe 4 and is covered pipe 7, one side of covered pipe 7 is provided with inside gasbag 8, the outside of inside gasbag 8 and covered pipe 7 is provided with guide spring 9, guide spring 9's one end bonds with tip end cap 2 mutually, guide spring 9's the other end is connected with connecting pipe 10, guide spring 9's externally mounted has outer tube 11, the one end and the tip end cap 2 intercommunication of inside gasbag 8, the other end is connected with connecting pipe 10, the inside of connecting pipe 10 is provided with the passageway, inside gasbag 8 is connected through this body pipe 6 of passageway of connecting pipe 10.

The working principle is as follows:

when treating the patient, can use and have the utility model discloses the intestines nutrition pipe of device or ileus pipe pass through human stomach pylorus smoothly, has shortened to a certain extent and has put the pipe time, has alleviateed patient's misery, and this device theory of operation is through the natural wriggling help pipe of self gravity and human stomach intestines and stomach through the stomach pylorus, and needs the doctor to guide this device to alternate the position and help this device to reach the affected part through the pylorus at putting the pipe in-process, in the actual clinical use process, the doctor can be according to the different directions of actual conditions adjustment of disease.
