In the above technical scheme, the buffer cavity is a spherical buffer cavity.

In the above technical solution, the diameter of the spherical buffer cavity parallel to the axis of the inner tube is located below the axis of the inner tube.

In the technical scheme, scales are arranged in front of the rear buffer cavity of the outer tube on the inner tube.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. the utility model has the advantages that the nested outer tube and the nested inner tube are arranged, the air bag is arranged at the front end of the outer tube, when feeding is needed, the inner tube is pushed to the food outlet hole at the front end of the inner tube to expose the air bag at the front end of the outer tube, and the front end of the inner tube is wrapped by the air bag to prevent the inner tube from puncturing the mucous membrane inside the child;

2. the utility model arranges the buffer cavity on the inner tube, so that the fluid food is buffered by the buffer cavity and then sent into the stomach of the child, thereby effectively preventing the stomach of the child from being stimulated by artificial too fast injection and avoiding discomfort;

3. the utility model can prevent the backflow of the fluid food, especially prevent the backflow of the fluid food which is vomited due to regurgitation of children by arranging the one-way valve in the connecting part of the inner tube;

4. the utility model discloses a set up the scale on the inner tube, make things convenient for the distance that operating personnel accurate control inner tube removed for the outer tube, ensure that the inner tube front end is wrapped up by the gasbag on the outer tube.

Drawings

Fig. 1 is a structural diagram of a first embodiment of the present invention.

Wherein: 1. an outer tube; 2. an inner tube; 3. an air bag; 4. a through hole; 5. a food outlet; 6. a buffer chamber; 7. a connecting portion; 8. a one-way valve.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows:

referring to fig. 1, the feeding tube comprises an outer tube 1 and an inner tube 2 inserted in the outer tube and capable of moving relative to the outer tube, wherein an air bag 3 is arranged at the front end of the outer tube, a through hole 4 for the front end of the inner tube to pass through is formed in the middle of the air bag, the front end of the inner tube is of a hemispherical structure, a feeding hole 5 is formed in the front end of the inner tube, a buffer cavity 6 is formed in the inner tube behind the outer tube, a connecting portion 7 connected with an injector is arranged at the rear end of the inner tube, and a one-way valve 8 is arranged in the connecting. The air bag is made of elastic medical rubber, when the front end of the inner tube does not penetrate through the air bag, the through hole in the middle of the air bag is tightly closed or partially closed, when the feeding is needed, the front end of the inner tube stretches the through hole in the middle of the air bag and penetrates through the through hole, so that the food outlet hole exposes the air bag, the front end of the inner tube is wrapped by the air bag, the feeding is convenient, and the mucous membrane can be prevented from being punctured by the front end of the inner tube.

In this embodiment, the inner wall of outer tube is equipped with the internal thread, the outer wall of inner tube is equipped with the external screw thread, be connected through internal thread and external screw thread cooperation between outer tube and the inner tube. The telescopic movement of the inner pipe relative to the outer pipe can be realized by rotating the inner pipe.

In this embodiment, the air bag is an annular air bag.

In this embodiment, the buffer cavity is a spherical buffer cavity. Specifically, the diameter of the spherical buffer cavity parallel to the axis of the inner tube is positioned below the axis of the inner tube. Therefore, the flow state food has larger buffer space, and the buffer cavity has better buffer effect.

In this embodiment, the place ahead that is located the rear cushion chamber of outer tube on the inner tube is equipped with the scale, makes things convenient for operating personnel accurate control inner tube for the distance that the outer tube removed, ensures that the inner tube front end is wrapped up by the gasbag on the outer tube.

The utility model discloses a theory of operation does: when feeding is needed, the inner tube is rotated to move forwards until the food outlet hole at the front end of the inner tube is exposed out of the air bag, the front end of the inner tube is wrapped by the air bag, the scale on the inner tube can be referenced, and then the injection head of the injector filled with the fluid food is inserted into the connecting part to inject and feed.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the above-described embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
