Description

Multifunctional bite-block

Technical Field

The utility model relates to the field of medical equipment, in particular to a multifunctional bite block.

Background

Currently, in clinical treatment of patients with respiratory dysfunction or for cardiopulmonary resuscitation and general anesthesia, tracheal intubation is one of the important measures. During the tracheal intubation, the bite of the tracheal intubation is prevented mainly by using a bite block, and the tracheal intubation needs to be fixed; at present, 3M adhesive tapes are mainly adopted for fixing the tooth pads and the tracheal cannula and fixing the tooth pads and the face of a person who is intubator, the 3M adhesive tapes are easily soaked by secretions in the oral cavity, so that the fixing force between the tooth pads and the oral cavity is weakened, the tooth pads are easy to shift and even pushed out of the oral cavity by the tongue body of the person, the tracheal cannula is easy to slide or deform due to the weakening of the fixing force between the tooth pads and the tracheal cannula, the risk of accidental falling and damage of the tracheal cannula is increased, and the treatment of the person is not facilitated; meanwhile, the adhesive plaster can leave offset printing on the face of a patient after being torn, the appearance is not attractive, allergic reaction of the patient can be caused, and the efficiency is low. Trachea cannula mostly fixes outside the bite-block among the prior art, and not only occupation space is big, and the patient still interlocks the pipe wall easily, leads to trachea cannula to warp and damaged, so a multi-functional bite-block needs urgent research and development.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model provides a multifunctional bite-block has can be comparatively reliable fixed bite-block and trachea cannula, occupy patient's oral cavity space little, can not leave adhesive tape seal of a government organization in old china, simple structure, convenient operation, improve the advantage that patient used and experienced.

The technical scheme of the utility model is that:

the utility model provides a multifunctional bite-block, includes cylindric bite-block body, this internal trachea jack the same rather than the axle direction that is equipped with of bite-block, the bite-block body includes first bite-block body and the second bite-block body that personally submits mirror symmetry distribution as the symmetry with the plane of crossing its axis, the one end of first bite-block body and second bite-block body is articulated, the terminal surface laminating of the other end, the inboard of first bite-block body and the articulated one end of second bite-block body is equipped with the torsion spring who connects first bite-block body and second bite-block body, the cover is equipped with the baffle on the lateral surface of first bite-block body and second bite-block body respectively.

The working principle of the technical scheme is as follows:

the utility model can effectively prevent the trachea cannula from being occluded. The utility model is provided with the baffle, avoids using 3M adhesive tape to fix the tooth pad body and the trachea cannula, fixes the tooth pad body by clamping the baffle between the teeth and the lips of the patient, not only can prevent the tooth pad body from sliding into the oral cavity, but also can prevent the tooth pad body from sliding out of the oral cavity, avoids leaving adhesive tape imprints on the face of the patient, has simple structure and convenient use; through settling trachea cannula on the inside trachea cannula of bite-block body, reduced the patient oral cavity space that occupies, improved the comfortable degree of patient's treatment, simultaneously, can prevent effectively that trachea cannula from by the patient interlock, avoid the pipeline to warp the damage for trachea cannula obtains accurate protection, improves patient's travelling comfort and tolerance. Through being equipped with torsion spring, can open bite-block body, when necessary, can take out fast or install trachea cannula.

When in use, one end far away from the baffle is stretched into the oral cavity of a patient, the baffle is tightly attached to the outer wall of teeth and the inner wall of lips of the patient, and a tracheal cannula is gradually inserted into the tracheal cannula; after the pipe is pulled out, can directly open the two halves of bite-block body, make things convenient for trachea cannula's adjustment, change and washing, can use repeatedly same patient after the bite-block body disinfection, alleviate patient's economic burden.
