Description

A kind of tracheal cannula fixer

Technical field

This utility model relates to technical field of medical instruments, particularly a kind of tracheal cannula fixer.

Background technology

Tracheal intubation is applicable to the patient needing to carry out airway management, the current method for fixed air cannula is normally after determining intubate success, bite-block is inserted up and down between front tooth of patient, with adhesive plaster, tracheal intubation and bite-block strapped side by side are fixed, finally with adhesive plaster, tracheal intubation is fixed on the Face and cheek of patient.This method weakens along with adhesive plaster viscosity, and conduit easily gets loose, misplace, and the tube drawing of unplanned property even occurs.In addition catheter position is not easy to regulate its insertion depth as required after fixing; Be not easy to medical personnel and clear up sputum in patient's mouth; Adopt rubberized fabric adhere that some patients also can be made to occur skin allergy.

Utility model content

The purpose of this utility model is for the deficiencies in the prior art, provides a kind of tracheal cannula fixer, and this holder can according to the size of trachea and adjusting tightness, more firm to fixing of trachea, during mouth care, do not worry that trachea is deviate from, thoroughly can clear up oral secretion.

For solving the problem, this utility model provides following technical scheme:

A kind of tracheal cannula fixer, comprises holder, trachea folder, button and shell fragment; The both sides of described holder are one-body molded retainer ring; Described holder is provided with the chute for installing described trachea folder; The both sides of described chute offer a toothrow groove respectively; Described button is rotatable to be installed on described trachea folder; The portion integral of described button forms the positioning tooth matched with described teeth groove; Described shell fragment is located between trachea folder and button.

Further, described holder is provided with for installing the mount pad of trachea folder and the stationary gripping part for clamping trachea; Described chute and described teeth groove are all located on trachea folder mount pad.

Further, described trachea presss from both sides to comprise and can be inserted to the insertion section in described chute and the movable clamping part for clamping trachea; Described insertion section is provided with for the lower bayonet slot of fixing described shell fragment bottom and the button holder for fixing described button; One-body molded on described button holder have locating shaft.

Further, the stage casing of the bottom of described button is provided with the locating hole coordinated with described locating shaft; Described button bottom is provided with the upper draw-in groove for fixing described shell fragment upper end; Described upper draw-in groove and positioning tooth lay respectively at the both sides of described locating hole.

Beneficial effect: a kind of tracheal cannula fixer of the present utility model, can according to the size of trachea and adjusting tightness, and fixing relatively firmly trachea, during mouth care, does not worry that trachea is deviate from, thoroughly can clear up oral secretion.
