A kind of lower jaw support and working method

Abstract

The invention provides a lower jaw lifting frame, which comprises a frame body and a bracket component; the bracket component comprises a base and a stretching mechanism; the stretching mechanism comprises a first stretching rod and a second stretching rod; the first stretching rod crosses through the base and points to the frame body, and the second stretching rod is opposite to the first stretching rod; the second stretching rod is connected with a holding rod through a link rod mechanism, and the link rod mechanism comprises a short link rod and a long link rod; one end of the long link rodis fixed with one head of the holding rod, and the other end of the long link rod is hinged with the second stretching rod; one end of the short link rod is fixed with the other head of the holding rod, and the other end thereof is hinged with the long link rod. Compared with the prior art, the lower jaw lifting frame can completely replace the manual lifting and oropharynx air duct at present, thus the intravenous anesthesia is more comfortable, safer, labor-saving and higher in efficiency. The invention further provides a working method of the lower jaw lifting frame.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a jaw lifting frame and a working method. Background technique [0002] At present, there are many clinical patients who need intravenous anesthesia, which refers to non-intubated general anesthesia, such as endotracheal intubation and laryngeal mask. After the patient is anesthetized, some spontaneous breathing may remain or disappear. This is because the patient’s tongue will drop, which seriously affects ventilation, resulting in unsmooth breathing and prone to intraoperative hypoxia. [0003] The current common clinical solution is to artificially lift the mandible or place an oropharyngeal airway. Manual jaw lifting requires the anesthetist to lift the patient's jaw forward and upward with both hands, which is laborious and time-consuming. Especially if the duration is more than 10 minutes, it will be very laborious, and most of the clinical operations under intr...

AI Technical Summary

Problems solved by technology

But in fact, the clinical effect of this method is not good. First, the oropharyngeal airway occupies the only limited space in the oral cavity, which affects ventilation on the one hand, and is not conducive to the discharge of oral secretions on the other hand. Saliva and other secretions near the door

At the same time, for operations performed in the mouth, such as painless gastroenteroscopy, intraoral hemangioma injection, etc., the root cannot be used, which affects the operation

And placing the oropharyngeal airway will also bring unnecessary accidental damage, such as oral mucosa, teeth, etc.
