The embodiment of the present utility model is realized in this way:

A connection structure for a sputum suction device, the connection structure is used for connecting a negative pressure joint and a sputum suction pipe joint, and the connection structure comprises a first pipe body, a middle pipe body and a second pipe body which are connected in sequence;

The inner side wall of the first pipe body is configured with a first inner collar, so that a first interlayer is formed between the first pipe body and the first inner collar; the inner side wall of the second pipe body is provided with a second inner collar ring, so that a second interlayer is formed between the second pipe body and the second inner collar; the negative pressure joint is embedded in the first interlayer, and the suction pipe joint is embedded in the second interlayer.

The beneficial effects of the present utility model are:

The connecting structure is embedded and connected with the negative pressure joint and the suction pipe joint respectively, which is not only convenient for connection, but also can ensure that the connecting structure will not slip off, and will not cause the sputum to be exposed during the suctioning process.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

It should be noted that like numerals and letters refer to like items in the following figures, so once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

<Example>

As shown in FIG. 1 , this embodiment discloses a connection structure for a sputum suction device. The connection structure is used to connect a negative pressure joint and a sputum suction pipe joint. the tube body 120 and the second tube body 130;

The inner side wall of the first pipe body 110 is configured with a first inner collar 210, so that a first interlayer is formed between the first pipe body 110 and the first inner collar 210; the inner side wall of the second pipe body 130 is configured with a second inner collar 210 The collar 220 forms a second interlayer between the second pipe body 130 and the second inner collar 220; the negative pressure joint is embedded in the first interlayer, and the suction pipe joint is embedded in the second interlayer.

The connecting structure is embedded and connected with the negative pressure joint and the suction pipe joint respectively, which is not only convenient for connection, but also can ensure that the connecting structure will not slip off, and will not cause the sputum to be exposed during the suctioning process.

In this embodiment, both the first inner collar 210 and the second inner collar 220 are made of elastic materials. The elastic material can be made of medical polymer elastic material. Using the elastic first inner collar 210 and the second inner collar 220 not only facilitates the embedding of the negative pressure joint and the suction pipe joint, but also the elastic material can be tightly attached to the surface of the joint to ensure firmness.

In this embodiment, friction particles 230 are disposed on the inner side of the first inner collar 210 and the inner side of the second inner collar 220 . By arranging the friction particles 230, the friction force between the inner ferrule and the joint can be increased, and the accidental slippage of the joint caused by accidentally being contaminated with liquid can be avoided.

In this embodiment, the first inner collar 210 includes a large head 211 and a small head 212 , and the small head 212 is integrally formed with the inner side wall of the first pipe body 110 .

In this embodiment, the second inner collar 220 includes a large head 211 and a small head 212, and the small head 212 is integrally formed with the inner side wall of the second pipe body 130.

By arranging inner ferrules with different diameters, the connection tightness between the connection structure and the joint embedding can be increased, and the possibility of slippage can be reduced at the same time.

In this embodiment, both the outside of the first pipe body 110 and the outside of the second pipe body 130 are provided with anti-skid lines 140 . The setting of the anti-skid pattern 140 is convenient for the operator to operate the joint and the inner collar.

In this embodiment, the first tube body 110 is screwed to the middle tube body 120 , and the second tube body 130 is screwed to the middle tube body 120 .

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
