Technical Field

The invention belongs to a medical apparatus, in particular to an auxiliary monitoring device for otorhinolaryngology endoscopy.

Background

Obstructive sleep apnea-hypopnea syndrome (OSAHS), commonly known as snoring, is a common chronic disease characterized by the repeated occurrence of upper airway collapse obstruction, snoring and apnea, intermittent hypoxemia, and sleep structure disorders during sleep. OSAHS can cause damage to multiple organs such as heart, cerebral vessels, endocrine and the like, is an independent risk factor and source diseases of various systemic diseases such as hypertension, coronary heart disease, diabetes, cerebrovascular accident and the like, and is closely related to sleep sudden death. OSAHS is widely considered to be a systemic disease, and all causes of stenosis at any part of the nose, pharynx and throat can be pathogenic factors of OSAHS. Statistics show that the prevalence of OSAHS in adults is 10% and that in elderly obese people is as high as 50%. Because of drowsiness and inattention, the work efficiency of people suffering from OSAHS is low, and traffic accidents and potential safety hazards are easy to happen particularly. The world's multi-national health organization has classified it as a significant disease that jeopardizes human health and quality of life. The clinical examination and diagnosis methods of OSAHS are many, and the most important methods are polysomnography and nasopharyngoscope imaging examination. Polysomnography mainly judges whether a patient is diagnosed with OSAHS and the severity of the condition of the patient, and nasopharyngoscope imaging examination is mainly used for judging the position of the patient with the upper airway obstructed and collapsed, anatomical stenosis factors and reasons of obstruction. When the nasopharyngoscope is clinically used, a patient often holds the nose to inhale forcefully during examination, and a MULLER test is carried out to see the collapse degree of the palatopharyngeal plane and the glossopharyngeal plane in a negative pressure state so as to judge the compliance of upper airway soft tissues and parts and reasons of possible stenosis blockage. However, when the MULLER test is performed, the degree of nasal force and the accuracy of the operation of the patient can affect the examination result. Therefore, it is desirable to monitor the airway pressure during the upper airway examination in real time to see the changes in cross-sectional area of the palatopharyngeal and glossopharyngeal planes under different pressure conditions. In addition, when performing a eustachian tube function test in the otolaryngological department, there is a common method of observing the degree of movement of the tympanic membrane. When the ear endoscope examination is carried out, a patient pinches the nose to inflate (carries out VASAVAL action), the eustachian tube is opened by increasing the pressure of the nasopharynx part, if the tympanic membrane can be swollen, the tympanic membrane can recover the original position after swallowing, and the eustachian tube has better function. The different pressures required to pinch the nasal tympanostomy tube open are significant in determining the outcome of the examination: an abnormally open eustachian tube may be characterized by an under-opening pressure, or by an under-opening or non-opening pressure. This examination also requires pressure monitoring of the upper nasopharyngeal airway to be performed accurately. The existing ear-nose-throat endoscopy does not have a device for monitoring the upper airway pressure in real time, and the invention designs the following technical scheme in order to solve the problem.
