Description

Technical Field

[0001] The invention relates to the technical field of semiconductor laser therapeutic apparatuses, in particular to a multi-point wearable semiconductor laser therapeutic apparatus for the neck and chest. Background Art

[0002] The working principle of semiconductor laser is based on the energy band transition of semiconductor materials. Through excitation, electrons jump between energy bands to emit light, and use the cleavage surface of semiconductor crystal to form a resonant cavity to achieve radiation amplification of light, which not only improves the output efficiency of laser, but also reduces the energy consumption and cost of equipment. The mechanism of action of semiconductor laser comprehensive therapeutic device mainly includes the following aspects: Biological regulation: Laser irradiation can enhance the body's immune function, regulate endocrine, and achieve bidirectional regulation of blood cells; Tissue repair: Laser can promote the growth of new blood vessels and granulation tissue proliferation, stimulate protein synthesis, and thus accelerate wound healing; Anti-inflammatory and analgesic: Rapid anti-inflammatory and analgesic effects are achieved by inhibiting nerve excitability, dilating blood vessels, and increasing pain thresholds.

[0003] Semiconductor laser comprehensive therapy devices usually use lasers of specific wavelengths (such as 650nm, 810nm, etc.), which have good tissue penetration and biocompatibility. For example, 810nm lasers can penetrate 5-7 cm of subcutaneous tissue and are suitable for deep tissue treatment. In addition, the device also has the function of intelligently adjusting the laser intensity, which can automatically adjust the output power according to the treatment needs.

[0004] At present, the existing semiconductor laser therapeutic apparatus has the following technical problems in the specific use process:

[0005] When realizing multi-point wearing on the neck and chest, multi-point treatment of the neck and chest is realized at the same time, a connecting shell needs to be set up to assist in realizing the connection between the chest and the neck. In actual use, if this wearing shell is designed as an integrated unit with the chest laser therapy device, it will be inconvenient to disassemble, repair, clean and replace the chest laser therapy device.

[0006] During the use of the chest laser therapy device, different user groups have different torso sizes. When wearing and fixing the chest laser therapy device, the practical needs of people of different body sizes cannot be met at the same time. The adaptability is poor, and users can only endure the discomfort. It is difficult to adjust the relative position relationship between the strap and the chest laser therapy device.

[0007] There is a lack of a structure to assist in achieving fixed contact between the chest laser treatment device and the chest skin. During the laser treatment, the chest laser treatment device is prone to shifting away from the acupuncture points to be treated, resulting in a weakened treatment effect.

[0008] In hot weather, some people who sweat easily will be affected to a certain extent by sweat when using chest laser therapy devices, resulting in reduced treatment effectiveness.

[0009] Therefore, our company has made improvements to address the above issues. Summary of the invention
