Description

Oral trachea cannula fixer

[ technical field ] A method for producing a semiconductor device

The utility model relates to a through mouthful trachea cannula fixer.

[ background of the invention ]

Tracheal intubation is one of the important technologies for clinical anesthesia, emergency treatment and critical care, is a prerequisite and important guarantee for successful effective respiratory management, and is also an important method for achieving the purpose of maintaining ventilation and oxygenation.

Clinically, generally, a trachea cannula is inserted into an oral cavity, the position is adjusted, after the trachea cannula is successfully inserted, the trachea cannula is fixed by adopting an oral trachea cannula fixing device, when the trachea cannula is fixed by the oral trachea cannula fixing device in the current market, the locking operation of a fastening device is not simple, convenient and quick enough, for example, the technical product with the authorized bulletin number of CN204890875U, after the trachea cannula is inserted, a cover plate is covered, a fastening bolt on the cover plate is installed in a mode of facing to a bolt hole on a base, and then the fastening bolt is screwed for fixing, wherein the correct alignment and installation of the fastening bolt and the screwing of the fastening bolt consume time, in addition, the body of a patient in many use occasions is continuously twisted and struggled, so that the trachea cannula is fixed to have inconvenience, the operation time is prolonged, and in many rescue and severe treatment, the time is life, the race is performed at the following time, one second is wasted, and one more risk is caused for life.

In addition, many binding bands of the oral and tracheal cannula fixator are fixed by tightening the neck through elastic bands, and the peripheral sizes of the oral and neck of different patients are different, so that the binding bands are too tight, pain is caused, skin pressure injury is caused even in long-time binding use, or the binding bands are loose and easy to loosen, and the tracheal cannula is not fixed stably. In order to solve the problem, the fastening button is fixed on the binding band in the market, and the binding band is fixed through the fastening button after being tightened, and one problem of the fixing mode is that the length size of the tightened binding band is relatively fixed, and different sizes and models of oral tracheal cannula fixing devices are required to be equipped for patients with large peripheral size difference between mouths and necks. However, since the rescue is time-consuming, the patient can temporarily select the proper type of oral tracheal cannula fixer after the patient comes, which obviously causes unnecessary time loss. In addition, clinically, the two binding modes usually require the head of the patient to be lifted and then the binding band to be put in or pass through the lower part of the neck, so that the movement of the limbs of the patient is large, and the discomfort of the patient is easily aggravated.

The present invention is made based on such a situation.
