Background

Hair loss is a common dermatological disease that, while not affecting the physical health of the patient, can severely affect the mental health and quality of life of the patient. The investigation of the alopecia population released by the national Weijian Commission in 2019 shows that the alopecia population in China exceeds 2.5 hundred million, the female and young alopecia trend is obvious, and 60 percent of people have alopecia in the age of 25. Alopecia has complex etiology and often medical microcirculation dysfunction, and the main manifestations include slow blood flow and blood viscosity. Existing treatment regimens include hair transplantation, oral or topical drug therapy, and low-energy laser physiotherapy.

The hair transplantation is mainly to take human hair follicles as a hair source, separate the hair follicles into single or multiple hair follicle units, transplant the hair follicles by a fine microsurgery technology, and survive on a new part to achieve the beautiful effect. However, the method belongs to invasive treatment, the transplantation cost is high, and the method is not suitable for large-area chronic alopecia patients.

Drug therapy is mainly by oral administration of finasteride and topical minoxidil. Finasteride is a medicine for treating male pattern alopecia, but has side effects of impotence, ejaculation disorder, orchialgia and the like; minoxidil is the only drug currently available for treating male and female alopecia, but is also associated with side effects such as contact dermatitis, itching and headache.

The low-energy laser physiotherapy is mainly characterized in that the laser irradiates and penetrates into subcutaneous tissues to reach the vicinity of hair follicles, so that angiogenesis near the hair follicles is activated, the angiogenesis enters mitochondria of hair follicle cells, and ATP energy is excited, so that the proliferation and the metabolism of the hair follicle cells are accelerated. However, the treatment population has certain limitations and may be accompanied by side effects such as headache, pruritus, erythema, acne and the like.

The existing hair physiotherapy instrument adopts a laser dot matrix to radiate an area to be treated with physiotherapy, and the method is limited in treatment population and accompanied with side effects of different degrees; secondly, through ultrasonic imaging diagnosis and through ultrasonic irradiation physiotherapy, the diagnosis accuracy of the method is poor, a large amount of ultrasonic coupling agent needs to be smeared during treatment, the process is complicated, and the user experience is poor.

The physiotherapy mode is high in price and accompanied by side effects of different degrees, and the contact physiotherapy mode cannot bring better treatment experience to users.

In this embodiment, the multi-path power module 8 includes a rechargeable lithium battery for supplying power and a charging unit for charging the rechargeable lithium battery, the rechargeable lithium battery supplies power to the positive and negative high voltage of the ultrasonic transducer driving module, the digital circuit of the MCU control module and the HMI human machine interaction module, the multi-path power module 8 generates ± 50V and ± 10V voltages by using an isolated DC-DC switching power supply, and the multi-path power module 8 generates ± 5V, ± 3.3V and 1.8V voltages by using a linear voltage stabilization method for the digital circuit.

Fig. 3 is a flow chart of the operation of the space-coupled ultrasonic hair therapy apparatus in the embodiment of the present invention.

As shown in fig. 3, when the user starts the air-coupled ultrasonic hair therapy apparatus 10, the operation flow of performing hair therapy (i.e. the air-coupled ultrasonic hair therapy method) by using the air-coupled ultrasonic hair therapy apparatus 10 is as follows:

step S1, the high-definition camera module 2 collects hair follicle image information of the area to be treated with physical therapy;

step S2, the MCU control module 5 adopts an intelligent image recognition processing algorithm to diagnose the hair follicle state of the to-be-treated physical therapy region for the collected hair follicle image information;

step S3, the MCU control module 5 actively searches the expert database to self-adaptively match the hair physical therapy mode corresponding to the hair follicle state;

step S4, the MCU control module 5 transmits a control timing signal of the corresponding physiotherapy mode to drive the ultrasound transducer driving module 4;

step S5, the ultrasonic transducer driving module 4 drives the air-coupled ultrasonic transducer module 3 to work;

in step S6, the space-coupled ultrasound transducer module 3 transmits low-intensity pulsed ultrasound to the hair follicle region to be treated for hair treatment.

Examples effects and effects

According to the space coupling ultrasonic hair physiotherapy device and method provided by the embodiment, hair follicle image information of a region to be treated with physiotherapy is collected through the high-definition camera module, the MCU control module performs image recognition processing on the collected hair follicle image information, according to the recognized hair follicle state, the expert database is searched to automatically match the corresponding hair physiotherapy mode, and then a control time sequence signal is sent to drive the ultrasonic transducer driving module, and the space coupling ultrasonic transducer module is further driven to carry out physiotherapy. Still because the air coupling ultrasonic transducer module can launch low-intensity pulse ultrasonic to the hair follicle region that needs carry out the physiotherapy when carrying out the physiotherapy, consequently can also realize the real-time physiotherapy of non-contact, have high integration, low cost, small and exquisite portable and do not have the characteristics of ionizing radiation. The space-coupled ultrasonic hair physiotherapy device and the method in the embodiment can repair damaged hair follicles of a user, improve the problem of hair loss of the user, and shorten the hair generation long period.

The above-described embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above-described embodiments.

For example, in the above embodiment, the high definition camera module 2 has 4 high definition cameras, in other aspects of the present invention, the number of the high definition cameras 21 may also be adjusted according to actual situations, such as setting to 1, 2 or other numbers.
