Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a lower jaw lifting frame and a working method.
Background
At present, a lot of patients need to be subjected to intravenous anesthesia clinically, and the intravenous anesthesia refers to non-intubated general anesthesia, such as tracheal intubation and a laryngeal mask. When a patient is anesthetized, partial spontaneous respiration or spontaneous respiration disappearance can be remained, so that the tongue of the patient drops, ventilation is seriously affected, the breathing is unsmooth, and oxygen deficiency in the operation is easy to occur.
The current clinically prevalent solution is to manually lift the mandible or place the oropharyngeal airway. Manually lifting the chin requires the anesthesiologist to lift the patient's chin forward and upward with both hands, which is laborious and time consuming. Especially for durations above 10 minutes, would be very laborious, whereas in most clinical cases the procedure under intravenous anaesthesia would exceed 10 minutes.
Meanwhile, the lower jaw of some patients is hypertrophied, and is very tight along with slight hypoxia during anesthesia, so that the lifting of a male doctor is very laborious, and the female doctor is needless to say. Therefore, the support person is often replaced, otherwise, the ventilation effect is not good, the anesthesia risk is increased, the manpower of an anesthesia physician is occupied, and the manpower is wasted and unsafe for a large number of operations in many hospitals at present.
And the other oropharyngeal airway is a bent hollow channel arranged in the mouth, and the tongue body is pulled open so as to avoid blocking the glottis and influencing the ventilation. However, the method is not effective after clinical use, and firstly, the oropharyngeal airway occupies only limited space in the oral cavity, which affects ventilation on the one hand, is not beneficial to discharge oral secretion on the other hand, and is not beneficial to anaesthetists to suck secretion such as saliva of glottic accessory and the like. Meanwhile, for operations which are only done in the mouth, such as painless gastrointestinal endoscopy, hemangioma injection in the oral cavity and the like, the root cannot be used, and the operation is influenced. And unnecessary accidental injuries such as oral mucosa, teeth and the like can be caused by placing the oropharyngeal airway.
Therefore, there is a need for a chin rest and method of operation that addresses the above issues.
