Description

OSA head fixing device based on 3D printing

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a OSA head fixing device based on 3D prints.

[ background of the invention ]

OSA refers to obstructive sleep apnea, in which an adult who sleeps 7 hours per night has episodes 30 or more while sleeping, and at each episode, the flow of the oral and nasal airflows is stopped for 10 seconds or more with a decrease in blood oxygen saturation, etc. Clinically, obese patients are more, the obese patients are easy to have OSA, muscles of old patients are easy to relax, and tongue root and suffix are easy to cause upper airway obstruction and sudden death. At present, the common correction devices for treating sleep apnea at home and abroad have the following types: 1. the snore stopper can lead the lower jaw to move forwards or the tongue body to extend forwards, thereby enlarging the airway behind the tongue and reducing snore, but the snore stopper needs to be used in the oral cavity and has an influence on the sleeping quality of part of patients; 2. the lower jaw bandage can prevent mouth opening breathing during sleeping, close the mouth and relieve snoring, but has poor effect in actual use, and the bandage is tightly hooped to influence the sleeping of a patient more easily; 3. the lower jaw support and lower jaw fixing device in the prior art basically adopts metal materials combined with hardware fittings and is individually combined with soft packing materials, but the fit degree with the lower jaw-neck of an individual is poor, the comfort level is poor and the curative effect is limited.

Chinese patent application CN215426779U, published date: 2022.01.07 discloses an adjustable lower jaw holds in palm open external member of ventilating of supplementary air flue that combines oxygen face guard, including arc extension shell, the both sides of arc extension shell are provided with right shell and left shell respectively, and the surface of right shell is provided with right handle cover, and the surface of left shell is provided with left handle cover, and the surface of right handle cover is pegged graft and is had right support cheek pole, and the tip of right support cheek pole is provided with right support cheek board, and right support cheek pole is connected on the surface of swivel lever seat, and the guide way has been seted up on the surface of swivel lever seat, and the inside of guide way is pegged graft and is had the angle restriction pole. The advantages are that: the provided multidirectional adjusting type clinical airway opening and setting jaw support completely simulates an artificial airway opening oxygen supply technique, continuously improves the possible obstruction state of an airway, lightens the work burden of medical personnel, and prevents the risk caused by the deflection of the head of a patient; the structure is simple, and the operation is simple. Although the device can reduce the occurrence of sleep apnea and hypopnea, the device is made of metal materials, and if the device is used for the autonomous sleep of a patient, the comfort level of the patient can be reduced and the sleep of the patient is disturbed because the device is not breathable and is made of inappropriate materials.

However, no 3D printing-based OSA head fixing device has been reported for fixing the head of a patient, relieving the upper airway obstruction of the patient, avoiding the apnea of the patient, assisting the patient to push the lower jaw to the right position, and alleviating the snoring and the tongue root suffix during sleep.
