Preferably, the incision is a straight incision that divides the filter membrane into 2 filter petals.

Preferably, the incision is a cross-shaped incision, which divides the filter membrane into 4 filter petals.

Preferably, the cut is a star-shaped cut, which divides the filter membrane into a plurality of filter flaps.

Preferably, the material of the filtering membrane is silica gel, polypropylene or polyethylene.

Preferably, the inner wall of the mouthpiece body is provided with a raised circular ring, and the filter membrane is adhered to the circular ring. The utility model discloses an inner wall at the seaming body sets up bellied ring, is convenient for fix filtration membrane in the seaming.

Preferably, the outer wall of the front end of the mouthpiece is provided with anti-slip lines, and the anti-slip lines comprise protrusions arranged along the circumferential direction of the outer wall of the mouthpiece to prevent the mouthpiece from slipping.

Preferably, the cross section of the front end of the mouthpiece is rectangular or oval in shape, so as to facilitate occlusion.

Preferably, the filter membrane and the mouthpiece have an inclined angle in the circumferential direction, so that saliva can be further prevented from flowing into a detection instrument or instrument connected with the mouthpiece through the incision.

Preferably, the angle of inclination between the filter membrane and the circumferential direction of the mouthpiece is between 15 ° and 45 °, facilitating the introduction of the instrument while ensuring a good barrier effect of the filter membrane against saliva.

Compared with the prior art, the beneficial effects of the utility model are that:

Detailed Description

To better illustrate the objects, aspects and advantages of the present invention, the present invention will be further described with reference to specific embodiments. It will be understood by those skilled in the art that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the examples, the experimental methods used were all conventional methods unless otherwise specified, and the materials, reagents and the like used were commercially available without otherwise specified.

The disposable mouthpiece, as shown in fig. 1, comprises a mouthpiece body 1 with a through hole, a filtering membrane 2 is arranged in the mouthpiece body, and the middle part of the filtering membrane 2 is provided with a notch which divides the filtering membrane into at least 2 filtering flaps.

The utility model arranges the filtering membrane 2 in the mouthpiece, the filtering membrane 2 can block the saliva at one end of the user, prevent the saliva from flowing into the detecting instrument or the apparatus connected with the mouthpiece through the mouthpiece, and prevent the pollution; the introduction of the instrument is facilitated by providing the filtering membrane 2 with an incision.

In the present invention, as shown in fig. 2, the incision is a straight incision 3, the straight incision 3 will the filtering membrane 2 is divided into 2 filtering petals, and the related apparatus can be guided in through the straight incision 3.

In the utility model discloses in, as shown in fig. 3, the incision is cross incision 4, cross incision 4 will 4 filtration lamellas are cut apart into to filtration membrane 2, and relevant apparatus accessible cross incision 4 is leading-in.

In the present invention, as shown in fig. 4, the incision is a star-shaped incision 5, the star-shaped incision 5 divides the filtering membrane 2 into a plurality of filtering flaps, and the related instruments can be guided in through the star-shaped incision 5.

The utility model discloses in, filtration membrane 2's material is silica gel, polypropylene or polyethylene, and preferred silica gel has good elasticity, and the apparatus of being convenient for passes through the incision.

In the utility model discloses in, as shown in fig. 1, the inner wall of the seaming body is equipped with bellied ring 6, filtration membrane 2 is pasted on ring 6. The utility model discloses a set up bellied ring 6 at the inner wall of seaming body, be convenient for fix filtration membrane in the seaming.

The utility model discloses in, the front end outer wall of seaming is equipped with anti-skidding line, anti-skidding line includes the arch that sets up along the outer wall circumferencial direction of seaming.

In the present invention, as shown in fig. 5, the cross-sectional shape of the front end of the mouthpiece is rectangular or oval, which facilitates occlusion.

In the present invention, as shown in fig. 5, an inclination angle θ is provided between the filter membrane 2 and the circumferential direction of the mouthpiece. The filter membrane may be arranged parallel to the circumferential direction of the mouthpiece, i.e. the inclination angle θ is 0, and has a certain barrier effect against saliva, which is able to block saliva at the user's end, but when there is a lot of saliva, the blocked saliva will easily flow into the instrument connected to the mouthpiece through the incision. Therefore, when the filter membrane and the mouthpiece have an inclined angle in the circumferential direction, saliva can be further prevented from flowing into a detection instrument or instrument connected with the mouthpiece through the incision, and the saliva blocking effect of the filter membrane can be improved.

The inclination angle theta between the filter membrane 2 and the circumferential direction of the mouthpiece is too large, so that the area of the filter membrane 2 is large, and the appliance is easily blocked from passing through, and the inclination angle between the filter membrane 2 and the circumferential direction of the mouthpiece is set to be 15-45 degrees, so that the appliance is convenient to introduce while the good blocking effect of the filter membrane on saliva is ensured.
