Detailed Description

The invention is described in detail below with reference to the drawings and specific examples.

The utility model relates to an improved trachea cannula fixing bite-block, as shown in figure 1, comprising a bite-block body 10, a hoop 20 and an elastic band 30.

Bite-block body 10 includes hollow column's bite-block pipe 11, and sputum 12 is inhaled to the cavity formation that 11 centers of bite-block pipe link up, when the patient uses this bite-block for a long time, is convenient for absorb the sputum in the oral cavity. The top surface and the bottom surface of the bite-tube 11 are flat, and the left side surface and the right side surface 111 are both arc-shaped which are matched with the outer wall of the tracheal cannula 40 in shape, so that the bite-tube and the tracheal cannula can be seamlessly jointed.

The top surface and the bottom surface of the bite pipe 11 are respectively provided with vertical baffles 13 which are opposite up and down, and the baffles 13 can prevent the bite block from sliding into the oral cavity of a patient. Each baffle 13 is provided with two through holes 131. The baffle 13 divides the bite block body 11 into two sections, when in use, one section is contained in the mouth of a patient and is defined as an oral inner section, and the other section is positioned outside the mouth of the patient and is defined as an oral outer section.

In order to increase the friction force between the teeth and the bite tube 11 and facilitate the patient to bite the bite block, a plurality of ribs 14 are provided on both the top and bottom surfaces of the inner section of the bite tube 11.

As shown in fig. 1, the hoop 20 is disposed at the mouth outer section of the bite block body 10, and the hoop 20 realizes that the bite block is hooped on the tracheal cannula 40 to play a role in fixing. As shown in fig. 1, the hoop member 20 includes an inserting end 21 disposed at the connection between the top surface and the side surface of the bite block body 10 and a locking end 22 disposed at the connection between the bottom surface and the side surface, and the inserting end 21 and the locking end 22 can be fastened and fixed to each other. As a preferred embodiment, as shown in fig. 2, the hoop member 20 is a cable tie, the surface of the cable tie insertion end 21 is provided with a plurality of convex ratchet teeth, the cable tie locking end 22 is provided with a square insertion hole, a locking claw is arranged in the square insertion hole, the cable tie insertion end 21 is arranged in the square insertion hole of the locking end 22, and the ratchet teeth on the surface of the cable tie insertion end are clamped with the locking claw.

Two elastic bands 30 are provided, and two ends of the two elastic bands 30 are respectively fixed in two through holes 131 on the upper baffle 13 on the top surface and the bottom surface of the bite block body 10 to form an upper annular elastic band and a lower annular elastic band.
