Background

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is recurrent episodes of apnea and hypopnea caused by a stenosis or obstruction in one or more parts of the upper airway during sleep, and is manifested clinically by nocturnal sleep snoring with apnea and daytime sleepiness. Recurrent nocturnal hypoxia and hypercarbonate caused by apnea can lead to complications such as hypertension, coronary heart disease, diabetes, cerebrovascular disease, etc., even nocturnal sudden death. Statistics indicate that OSAHS ranks second to asthma in the incidence of various respiratory syndromes. This syndrome can affect age groups, and it is estimated that it can affect 2-4% of adults, but is more common in middle-aged men. 1 patient with moderate to severe OSAHS in every 5 adults and 1 patient with moderate to severe OSAHS in every 15, this disease presents great trouble to the patient himself and her family members.

The occurrence of OSAHS is associated with a number of factors, the most important of which are the decline in the pharyngeal distending muscle tone (e.g., genioglossus dysfunction) and ataxia of muscle inhalation and exhalation activity. Research and clinical experiments prove that the laser treatment of snoring and OSAHS is a safe, noninvasive and painless non-operative treatment means. The method adopts laser irradiation to stimulate oral mucosa, so as to reconstruct mucosa epithelium, denature and shrink collagen of mucosa lamina propria, regenerate and remodel collagen fiber and elastic fiber, and can tighten mucosa, increase mucosa elasticity, thereby realizing airway expansion and pharyngeal muscle expansion force improvement, and improving OSAHS symptom.

The control unit 6 is used for superposing the simulated airway image on the oropharynx image, fitting and determining a target area 10 needing laser physiotherapy, and controlling the laser module to carry out physiotherapy on oropharynx tissues of the target area. Specifically, the laser source 1, the laser output unit 2, the detection unit 3, the display unit 4 and the indication light source 5 are controlled by the control unit 6. Wherein, the laser source 1 generates a laser signal under the control of the control unit 6, and feeds back temperature and power information to the control unit 6; the laser output unit 2 adjusts the light output direction according to the instruction of the control unit 6, thereby changing the light irradiation position; the detection unit 3 is controlled by the control unit 6 to emit detection light and detect, and meanwhile, the detection result is fed back to the control unit 6; the display unit 4 receives the signal of the control unit 6 to display the corresponding image; the indication light source 5 generates an indication light signal according to the control of the control unit 6.

The working principle of the laser physiotherapy instrument is that the control and signal transmission method is as follows:

(1) The control unit 6 receives the sensing information on the oral cavity fixator 7 and confirms whether the user wears the oral cavity fixator 7;

(2) The control unit 6 sends a control signal to the laser source 1 to control the laser source 1 to generate a laser signal according to the set parameters, and meanwhile, the laser source 1 feeds back state parameters such as temperature, laser power and the like to the control unit 6;

(3) The control unit 6 controls the angle of the optical element in the laser output unit 2 to control the light emitting direction;

(4) When confirming that the position of the indicating light is a target area for physiotherapy, the laser output unit 2 feeds back the calibration position parameters to the control unit 6 and records the calibration position parameters by the control unit 6;

(5) The control unit 6 controls the detection unit 3 to emit detection light to detect the oropharynx of the user, and the detection unit 3 transmits detection information to the control unit 6;

(6) The control unit 6 controls the display unit 4 to display the detection result image fed back by the detection unit 3 and the simulated airway image;

(8) The control unit 6 is also connected to an emergency stop button 8, and when the emergency stop button 8 is closed, the control unit 6 receives an emergency stop instruction and performs control of turning off the laser source 1 and the like.

The working flow of the laser physiotherapy instrument is as follows: after the device is powered up, each unit is initialized. After the detection unit 3 and the display unit 4 are started and the oral cavity fixator 7 is detected to be worn by a user, the detection unit 3 feeds back the detection result of the oropharynx of the user, and then the display unit 4 displays images. The control unit fits the simulated airway on the user's oropharyngeal image by a preset algorithm and displays it by the display unit 4. Subsequently, under the instruction of the user, the control unit 6 controls the indication light source 5 to emit indication light, and records the position information of the target area calibrated by the user. After the calibration is completed, the control unit 6 controls the laser source 1 to emit laser signals according to the set parameters, and controls the mechanical rotating shaft in the laser output unit 2 according to the calibrated position information to radiate the laser signals to the target area.

The specific application method is as follows: after the equipment is electrified, a user wears the oral cavity fixator 7 and wears corresponding protective equipment (such as protective glasses), then the detection unit 3 is opened to detect the oropharynx, the detection result is observed through the display unit 4, then the simulated airway image is superimposed on the oropharynx image through the control unit 6, and the mucous membrane tissues of the soft palate and the palatoglossus, which are positioned in the simulated airway, are the target areas which need to be tightened through laser physiotherapy. Next, the indication light source 5 is turned on, the display unit 4 observes the position irradiated with the indication light, the user adjusts the light emitting direction of the laser output unit 2 by the control unit 6, and when the indication light irradiates the target area, the positioning is confirmed. After the calibration is completed, the laser source 1 is enabled to emit laser, the equipment carries out physiotherapy according to the target area position set in the last step, and the physiotherapy is ended after the set time is reached. During the physiotherapy, if the user feels uncomfortable, the user can immediately press the scram button 8 to stop the physiotherapy.

Specifically, an example of target area calibration is shown in fig. 4, wherein a dashed line shows a simulated airway contour 9, and a palate mucosal tissue located inside the dashed line is a target area 10 where laser physiotherapy is required, and the purpose of expanding the airway can be achieved by tightening the mucosal tissue in the target area through laser irradiation, so that snoring and OSAHS symptoms are improved. The simulated airway image can be automatically matched in a database pre-stored in the device by inputting relevant physical parameters (such as age, sex, height, weight, neck circumference and the like) of the user, and parameters such as airway diameter and the like can also be obtained according to the advice of doctors. For safety reasons, the parameter selection of the automatically matched simulated airway should be kept as conservative as possible, for example, the minimum airway size of the user symptom can be improved, and the damage caused by the laser radiation to other areas due to the overlarge target area of the laser physiotherapy is avoided.

The method ensures the safety of user operation by detecting imaging, airway fitting, oral cavity fixing and automatically controlling the light emitting direction according to the calibration position, is suitable for being used as household physiotherapy equipment, is convenient for daily physiotherapy of OSAHS patients and improves symptoms.
