Detailed Description

The utility model provides an anti-scratch bite-block, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following refers to the attached drawing and the embodiment is lifted the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 and 2, the utility model provides an anti-scratch bite block, which can be divided into an adult bite block and a child bite block according to applicable people, and is made of plastic material, and the structure and size of the bite block will be described by taking an adult bite block as an example. The bite-block includes body 1, the body is equipped with the tubular structure of circular through-hole 2 as the center, circular through-hole 2's size and trachea cannula's external diameter phase-match, and is specific, and body 1's length is about 50 ~ 60mm, and width and height are about 10 ~ 15mm, and middle through-hole diameter is about 9.5mm, and the (internal diameter) model of the trachea cannula that corresponds is 7# -8.5 #. Further, the body 1 is provided with an upper wing 3 and a lower wing 4 which are symmetrical up and down, and the upper wing 3 and the lower wing 4 are integrally formed with the body 1 and used for supporting the lips; and the upper wing 3 and the lower wing 4 are also provided with a perforation 5 in the direction perpendicular to the round through hole 2 for fixing the binding band. In the specific implementation process, the trachea cannula penetrates through the circular through hole in the middle of the tooth pad, then the trachea cannula is inserted into the airway, the tooth pad is placed between the upper tooth and the lower tooth, the position of the tooth pad is adjusted, then the binding band penetrates through the through hole of the upper wing or the lower wing, and the head is fixed through the binding band.

As shown in fig. 3, 4, 5, and 6, in the bite block of the above structure, a locking mechanism (including 8.1 and 8.2) is further provided at one end of the body 1 near the upper wing and the lower wing, the locking mechanism includes an inner ring 8.1 fixedly connected to the body and an outer ring 8.2 threadedly connected to the inner ring, the inner ring 8.1 is provided with two notches 8.3 symmetrical to each other, an inner diameter of the inner ring 8.2 is the same as a diameter of the circular through hole, a wall thickness of the inner ring is gradually increased from a top end to the body end, and an outer wall of the inner ring 8.1 is provided with a thread, and one end of the outer ring 8.2 connected to the inner ring is provided with an internal thread matching with the internal thread, and an inner diameter of the connecting end is gradually reduced from the port inward. When the tracheal cannula is used, the inner diameter of the inner ring can have certain contractibility due to the notch 8.3 arranged on the inner ring, the outer wall of the inner ring 8.1 tends to be gradually enlarged, and when the outer ring 8.2 is screwed, the inner ring wall is extruded, so that the inner diameter of the inner ring 8.1 is reduced (as shown in fig. 5), and the tracheal cannula can be adapted even if the tracheal cannula is small in pipe diameter. It should be noted that the diameter (inner diameter) of the adult endotracheal tube is generally 7-8.5 mm (i.e., 7# -8.5 #), so that the difference between the maximum tube diameter and the minimum tube diameter is about 1.5mm, and the minimum endotracheal tube can be completely locked by adjusting the locking mechanism. In the specific implementation process, the outer ring 8.2 and the inner ring 8.1 are unscrewed, then the tracheal cannula sequentially penetrates through the body 1, the inner ring 8.1 and the outer ring 8.2, and then the outer ring 8.2 is rotated until locking.

Specifically, in the bite block with the above structure, as shown in fig. 2, 4 and 6, arc-shaped grooves 6 are formed in two sides of the body 1, and the arc-shaped grooves 6 can be used for fixing trachea cannulas with larger tube diameters or other types of cannulas with larger tube diameters. In the specific implementation process, aiming at some trachea cannulas with large pipe diameters or other cannulas, the phenomenon that the cannulas cannot penetrate through the circular through holes formed in the middle of the bite block exists, the trachea cannulas or other cannulas can be tightly attached to the arc-shaped grooves, and then the trachea cannulas or other cannulas are fixed in the bite block through the binding bands.

Specifically, in the bite block with the above structure, the upper wing 3 and the lower wing 4 are arc-shaped projections with smooth surfaces. The upper wing and the lower wing are provided with the arc-shaped convex blocks with smooth surfaces, so that the upper lip and the lower lip can be prevented from being scratched, and the mouth lip is better protected compared with a flaky structure in the prior art.

Further, as shown in fig. 1, 3 and 5, in the bite block with the above structure, symmetrical alveolus 7 are further provided at the upper and lower surfaces of the middle part of the body. The tooth socket 7 has a limiting function and can limit the teeth to move back and forth, and in the specific implementation process, the tooth pad is stretched into the oral cavity, the position is adjusted until the teeth fall into the tooth socket, the tooth socket is in the optimal position, and then the tooth socket is fixed on the head through a binding band.

It is understood that equivalents and changes may be made to the technical solution of the present invention and its concept by those skilled in the art, and all such changes and substitutions shall fall within the scope of the appended claims.
