Description

Tracheal cannula fixer

Technical Field

The utility model belongs to the technical field of medical instrument technique and specifically relates to a trachea cannula fixer.

Background

The bronchofiberscope is a medical instrument which is placed in the lower respiratory tract of a patient through the mouth or the nose, is used for observing lung lobes, segments and sub-segment bronchial lesions, sampling biopsy, examining bacteriology and cytology, and can be used for shooting, teaching and dynamically recording by matching with a TV system. Through the connected biopsy sampling accessory, early lesions can be found, and operations such as polyp removal and the like can be carried out.

Before the operation, carry out general anesthesia to the patient earlier, put into patient's air flue and fixed with trachea cannula through patient's oral area, link to each other trachea cannula and breathing machine again and carry out supplementary ventilation, then examine bronchofiberscope through trachea cannula. The traditional fixing method of the tracheal cannula comprises the following steps: two wires are led out of the tracheal cannula, and then the two wires are tied and fixed around the back strength of the patient. The fixing effect is poor, the tracheal cannula is easy to move, and medical care personnel are influenced to observe a lesion part by using a bronchofiberscope; in addition, the tracheal cannula is a hose, if the patient unconsciously bites the teeth, the bronchofiberscope in the tracheal cannula is easy to bite, the teeth of the patient are easy to damage, the operation process is delayed, and the bronchofiberscope is expensive, so that the operation cost is increased.

SUMMERY OF THE UTILITY MODEL

To the technical problem that traditional trachea cannula fixed mode effect is poor, the bronchofiberscope is easily bitten bad by the patient, the utility model provides a trachea cannula fixer.

The utility model adopts the technical proposal that: the tracheal intubation fixer comprises a tooth socket, wherein the tooth socket comprises an upper incisor tooth socket and a lower incisor tooth socket, a semicircular upper groove is formed in one side, close to the lower incisor tooth socket, of the upper incisor tooth socket, a lower groove matched with the upper groove is formed in the lower incisor tooth socket, and the upper groove and the lower groove are encircled to form a round hole matched with the tracheal intubation; the outer side of the upper groove corresponding to the upper door tooth socket is provided with a first arc-shaped plate matched with the shape of the upper groove, the outer side of the lower groove corresponding to the lower door tooth socket is provided with a second arc-shaped plate matched with the shape of the lower groove, and the first arc-shaped plate and the second arc-shaped plate are enclosed to form a hollow cylindrical channel. The utility model discloses put into the facing in patient's oral cavity, be provided with the round hole that is used for trachea cannula to pass on the facing, be provided with the column passageway that is used for trachea cannula to pass moreover equally on the facing. During operation, a patient wears the tooth socket, and then the tracheal cannula sequentially penetrates through the channel and the round hole to be placed into an airway of the patient. Therefore, even if the patient bites unconsciously, the patient only can bite the tooth socket and cannot bite the tracheal cannula directly.
