Background

The stomach tube is used for helping a patient who cannot swallow to deliver necessary moisture and food under special conditions, one end of the stomach tube 10 is inserted into the stomach through the mouth, the other end of the stomach tube is positioned outside the patient body, the end is provided with a tail end connecting device which comprises a connecting tube 20 and a tube cover 30, and one end of the connecting tube 20 is communicated with the outer end of the stomach tube 10; an annular groove 31 is formed in an end surface of the cap 30, and the annular groove 31 is used for inserting the free end of the connection pipe 20, so that the cap 30 seals the free end of the connection pipe 20.

When a patient is fed with food, the tube cover 30 is taken down from the connecting tube 20, the free end of the pipeline 40 of the feeder is embedded into the connecting tube 20, and the feeder pushes the food in the connecting tube into the body of the patient through the stomach tube 10; after feeding and eating, food residues are left on the inner wall of the connecting pipe 20, the free end of the connecting pipe 20 is inserted into the annular groove 31 at the moment, the food residues are located in the annular groove 31 certainly, the annular groove 31 is narrow and cannot be cleaned completely, the residues in the annular groove 31 are increased after feeding for many times, bacteria are easily bred by the food residues, and the health of a patient is further harmed. In addition, in the multiple feeding process, the pipeline 40 of the feeder is inserted into the connecting pipe 20 for multiple times, so that the subsequent insertion connection between the pipeline 40 and the connecting pipe 20 is loosened, and the pipeline 40 of the feeder and the connecting pipe 20 are easily disconnected in the feeding process.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the pipe end connecting device and the matched food perfusion device, so that food residues are easy to clean in the pipe cover, and the connecting state of the pipeline of the feeder and the connecting pipe cannot be automatically disconnected.

In order to achieve the purpose of the utility model, the utility model adopts the technical scheme that:

the stomach tube end connecting device and the matched feeding device comprise a stomach tube, a connecting pipe, a pipe cover and a feeder pipeline;

one end of the connecting pipe is fixedly communicated with one end of the stomach tube, and the outer wall of the connecting pipe is provided with external threads;

the inner wall of the pipe cover is provided with pipe cover internal threads, and the pipe cover internal threads are matched with the external threads;

the inner wall of the free end of the feeder pipeline of the feeder is provided with a pipeline internal thread, and the pipeline internal thread is matched with the external thread.

Furthermore, the end wall of the tube cover is provided with a small hole which is used for feeding water to a patient, and the plug pin is detachably embedded into the small hole.

The utility model has the beneficial effects that:

internal threads are arranged on the inner wall of the pipe cover and the inner wall of the feeder pipeline, and external threads are arranged on the outer wall of the connecting pipe; even if the feeding is carried out for multiple times, the pipeline inner thread on the inner wall of the feeder pipeline is in threaded connection with the outer thread on the outer wall of the connecting pipe, so that the feeder pipeline cannot be automatically separated from the connecting pipe in the feeding process; the tube cover has no narrow gap, so that the tube cover is convenient to clean, food residue in the connecting tube can be reduced to a certain extent, food residue can be easily cleaned in the tube cover, and the connecting state of the pipeline of the feeder and the connecting tube cannot be automatically disconnected.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 4 to 6, the stomach tube end connecting device and the matching feeding device comprise a stomach tube 10, a connecting tube 20, a tube cover 30 and a feeding device pipeline 40;

and one end of the connecting pipe 20 is fixedly communicated with one end of the gastric tube 10, and the outer wall of the connecting pipe 20 is provided with an external thread 21.

The inner wall of the pipe cover 30 is provided with a pipe cover internal thread 31, and the pipe cover internal thread 31 is matched with the external thread 21.

Referring to fig. 5, the inner wall of the free end of the feeder line 40 of the feeder is provided with a line inner thread 41, and the line inner thread 41 is matched with the outer thread 21.

The principle is as follows:

the inner wall of the pipe cover 30 and the inner wall of the feeder pipeline 40 are provided with internal threads, and the outer wall of the connecting pipe 20 is provided with external threads 21; even if the feeding is carried out for multiple times, the inner pipeline thread 41 on the inner wall of the feeder pipeline 40 is in threaded connection with the outer thread 21 on the outer wall of the connecting pipe 20, so that the feeder pipeline 40 cannot be automatically separated from the connecting pipe 20 in the feeding process; after feeding and eating, medical personnel manually unscrew feeder pipeline 40 and connecting pipe 20, then combine with the tube cap internal thread 31 of tube cap 30 and the external screw thread 21 spiral of connecting pipe 20 to do not have constrictive gap in the tube cap 30, convenient clearance, and can reduce the food residue in the connecting pipe 20 to a certain extent, realize that the inside easy pipeline and the connecting pipe connection state of wasing food residue and feeder of tube cap can not automatic disconnection.

Further, referring to fig. 6, the end wall of the tube cover 30 is provided with a small hole 32, the small hole 32 is used for feeding water to the patient, and the plug pin 33 is detachably inserted into the small hole 32.
