Technical Field

The utility model relates to the technical field of optical device application, in particular to a distributed skin-friendly flexible laser cap.

Background

Alopecia caused by aging, hormonal dysfunction, stress, autoimmune diseases and chemotherapy is a problem that afflicts millions of people worldwide. Currently, the methods approved by the Food and Drug Administration (FDA) for treating alopecia mainly include drug therapy and Photo Biological Modulation Therapy (PBMT). At present, finasteride oral administration or minoxidil external application is mainly recommended as a medicine for treating alopecia clinically, and has certain probability of bringing about side effects, such as hirsutism, sexual dysfunction, fetal deficiency and the like, and the PBMT approved by the FDA in the United states for treating alopecia is mainly low-energy laser therapy (LLLT) with the wavelength of about 655nm, and the PBMT serving as a novel convenient noninvasive treatment method can promote hair growth through proved by clinical experiments of numerous animals and human bodies at home and abroad in recent decades, and has no obvious side effect.

Originally, laser physiotherapy equipment for treating alopecia is mainly a table type laser medical instrument used by hospitals and professional hair transplantation departments, the equipment is expensive, large and inconvenient to move, and is not convenient for patients to use every day.

Chinese patent CN106693210A discloses a hair growing helmet, which comprises a hat-shaped shell and a plurality of laser generating units arranged inside the hat-shaped shell, wherein the laser generating units emit elliptical light spots, and the light spots are arranged in a cross manner, so that laser irradiation is more uniform, which is beneficial to improving laser interest rate and improving treatment effect.

However, the hair growing helmet or the hair growing cap invented by the patents are all hard structures, are inconvenient to carry, and have different comfort levels and effects for users with different head circumference sizes; the distribution structure of the laser chips in the hat or helmet is also fixed, and for patients with local alopecia, the cost is increased due to the large-area laser layout, and waste is generated; the totally enclosed housing structure also greatly affects the breathability, bringing a bad experience to the user.

SUMMERY OF THE UTILITY MODEL
