Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a laser treatment device that produces acupuncture effects using semiconductor laser light.

Conventional Structure and Problems Conventionally, acupuncture and moxibustion have been used to treat affected areas of the human body, and it has recently been found that acupuncture and moxibustion effects can be obtained by performing these treatments with laser beams. Unlike traditional treatment methods, this laser treatment does not require needles to be inserted into the human body.
Additionally, unlike moxibustion, it does not give a hot sensation and is easy to handle, and devices that use helium neon lasers or semiconductor lasers as laser light have been developed. However, conventional devices have many problems in terms of safety and hygiene and handling of externally irradiated laser beams.

As a conventional example, there is a device 6 as shown in FIGS. 1 and 2. In this device, a laser beam 1 and a reflector 2 are installed in the optical path of a light beam from a semiconductor laser 4, and one laser beam is focused into a parallel beam and irradiated to the outside. Although this does not pose a problem for the skin of the human body, there is a risk that it may adversely affect the eyes if the eyeballs are accidentally irradiated with it. Further, since the laser beam can be irradiated freely by the switch 3, the operator must be careful in handling the device, and the operability cannot be said to be good. Furthermore, since the laser beam is a parallel beam, it can only irradiate to a certain depth under the skin of the human body, making it impossible to adjust to the depth of the affected area and making it impossible to increase the acupuncture effect any further. In addition, when irradiating the affected area with a laser beam, it is difficult to maintain a constant irradiation position without contacting the human skin. The contact parts of the device become dirty due to dirt, etc., which is not good for hygiene and requires cleaning.However, in conventional devices, the irradiation port is integrated with the main body, making it difficult to perform ultrasonic cleaning etc. There's a problem.

As mentioned above, the conventional device has many drawbacks.

OBJECTS OF THE INVENTION The present invention provides a laser treatment device that eliminates many of the drawbacks found in conventional devices and is superior in terms of safety and hygiene and is easy to handle.
