Description

Nasal cavity expansion snore stopper and intelligent snore stopping system based on snore recognition Technical Field The invention belongs to the field of medical appliances, and particularly relates to a nasal cavity expansion snore stopper and an intelligent snore stopping system based on snore recognition. Background Obstructive sleep apnea is a common sleep disordered breathing disease, the pathophysiology of which is based on repeated collapse or obstruction of the upper airway during sleep. The upper respiratory tract of the human body is a continuous soft tissue channel from the nasal cavity to the throat, wherein the nasopharyngeal cavity, the palatopharyngeal and the tongue root are key parts which are most prone to occurrence of stenosis or obstruction. When an individual sleeps in a supine position, the root of the tongue and the soft palate are easy to shift backwards due to the action of gravity and the decrease of muscular tension, so that the cross section area of a pharyngeal cavity is obviously reduced, soft tissue vibration is induced when airflow passes through the pharyngeal cavity, namely snoring is represented, and if obstruction is aggravated, apnea, blood oxygen saturation decrease and sleep fragmentation can occur. Epidemiological studies have shown that factors such as obesity, adenoid tonsil hypertrophy, craniofacial structural abnormalities, advanced age, and neurological disease can significantly increase the risk of occurrence of upper respiratory tract obstruction. In view of the above problems, the following intervention methods are mainly adopted in the prior clinical practice. Nasal cavity expansion instruments are placed in the vestibule or the threshold part of the nose and rely on mechanical support to expand nasal passages, but have limited scope of action and can not solve the obstruction of the palatopharyngeal and tongue root level. The oral appliance enlarges the pharyngeal cavity by advancing the mandible or pulling the tongue body, but the oral appliance is easy to cause adverse reactions such as temporomandibular joint discomfort, abnormal salivary secretion, tooth displacement and the like after being worn for a long time. Continuous positive airway pressure is a "gold standard" of non-surgical treatment in which positive pressure airflow is delivered to the airway through a mask to maintain airway patency, but its equipment is bulky, poor wearing comfort and noise problems result in generally low patient compliance. For a part of severe patients, surgery such as uvula palatopharyngectomy and the like can be clinically selected, but the surgery is large in wound and long in recovery period, and the risk of restenosis of the airway caused by postoperative scar contracture exists. The prior art has the defect that a nasal cavity expanding device which can achieve the functions of implantation safety, wearing comfort and multi-part support is lacked. The traditional instrument is easy to rub with the mucous membrane of the nasopharynx cavity and even stab the back wall of the pharynx due to the fixed front end and the larger section in the implantation process, and has higher bleeding risk for patients needing anticoagulation treatment or blood coagulation dysfunction. Meanwhile, the existing apparatus mostly adopts a static support design, the support force can not be dynamically adjusted according to the severity of the snoring disease and the breathing rhythm of the patient, and the graded intervention of the mild snoring disease and the severe snoring disease is difficult to realize. In addition, the existing functions are relatively single, and multiple clinical requirements of nasal cavity expansion, soft palate support, tongue root fixation, and prevention of soft tissue collapse around pharynx and the like are difficult to be met at the same time. Disclosure of Invention In order to solve the technical problems, the invention provides a nasal cavity expansion snore stopper and an intelligent snore stopping system based on snore recognition, so as to solve the problem that in the prior art, mucous membrane friction damage is easy to occur when an instrument is placed. The invention provides a nasal cavity expansion snore relieving device, which comprises: the soft arc body is provided with a soft pipe A end and a soft pipe B end which are opposite, the soft pipe A end is inserted from the nasal cavity and extends to the pharyngeal cavity, and the soft pipe B end is positioned outside the nasal cavity; the arc-shaped soft main body is provided with a preset radian, and further is provided with a hose small-bending side C and a hose large-bending side D; the bending control comprises a traction wire, and both ends of the traction wire are positioned outside the end B of the hose; Preferably, the traction wire penetrates into the arc-shaped soft main body from the hose B end and extends to the hose A end through the inner wall of the hose small-bending side C,
