The present invention relates to a low power laser irradiator equipped with an automatic on / off switch. More specifically, the laser is irradiated only when an on / off switch is provided on the skin contact portion of a low power laser irradiator used in a hospital, a home or a portable device. It relates to a low power laser irradiator with an automatic on / off switch.

Photochemical action on plants can be seen in carbon assimilation, and when light is irradiated to a living body, ATP is produced by the photochemical action to activate cells. In other words, if the laser light is irradiated to the living body at a low energy level so that the living cells are not damaged, skin disease treatment, hair growth promotion, allergy treatment, chronic arthritis, rheumatism, fifty shoulders, and acute low back pain Cervical spondylitis, hay fever, atopic dermatitis, asthma, hay fever, gout, sprains, bruises, arthritis, stressful bowel syndrome, chronic anal disorders of the urinary system, urinary system disease, hypertension and various brain diseases It is well known in the medical field that it has the effect of promoting natural healing power.

Recently, a low power laser irradiator for treating various diseases using the above action has been used in various disease treatment fields. For example, low-power laser irradiation for tinnitus shape and rhinitis treatment, and hair growth laser irradiation for treating baldness are widely used in hospitals. In addition, a variety of products, such as mattresses, pillows, cushions that emit low-power laser light is also being used in general homes. The low-power laser irradiator used in hospitals and homes is mostly using a semiconductor laser that operates in the infrared wavelength range, the risk of safety accidents increases as the field of use increases rapidly.

In particular, the conventional low-power laser irradiation products used in homes are composed of a wire with a plug connected to an external power source and a laser diode for irradiating laser light by a current applied to the wire.

Therefore, when the plug is plugged into the external power cord, the laser light is irradiated, and at this time, the user can see a predetermined therapeutic effect by irradiating the laser light to a specific site.

However, since the conventional laser irradiator does not have a separate safety device, when it is left unused while it is left unused while it is in use, the light of the laser irradiator is irradiated with the eyes of people nearby. There is a problem that can cause fatal damage to the retinal tissue of the soft eye. In addition, when the user wants to use the laser irradiator again, there is a similar problem when the laser irradiator visually checks to see if the power is turned on unconsciously.

In particular, exposure to the eyes of infants and children in the process of development and growth has a detrimental effect that can result in poor vision and even severe blindness.

In addition, there is a problem that the power is always turned on even when the laser irradiator is not used, such that power loss occurs.

On the other hand, while the conventional laser irradiator is provided with a switch that is manually operated on the wire for applying power, this also requires the user to manually turn on / off the power when using or not using the laser irradiator, the user If not used for a while cumbersome, the same problem is left as it is left in the power-on state.

The present invention has been made to solve the above problems, it is equipped with a switch that automatically turns on / off the power in a position in contact with the user's skin, when in use is turned on (ON) when the laser is irradiated and do not use It is an object of the present invention to provide a laser irradiator which can be turned off to prevent the laser from being irradiated, thereby protecting the eyes of the user and others from the laser light and preventing unnecessary waste of power.

And a lens 28 covering the laser diode 26.

On the other hand, the on / off switch 30 is attached to a predetermined position of the wire 16 for applying power to the light emitting unit 20.

The on / off switch 30 is provided inside the treatment unit body 10, but is preferably provided at the position of the skin contact portion in contact with the treatment unit body 10 and the human skin.

More specifically, the on / off switch 30 is preferably provided on the inside of the side of the seat hole inlet of the skin contact portion of the treatment device body 10 as in this embodiment, at any position in contact with the user's skin You may install it.

In addition, it is preferable that the on / off switch 30 is a micro switch embedded in the treatment body 10 as shown in FIGS. 1 to 4.

However, the on / off switch 30 can be used as long as the power can be cut off by the pressure generated when a person contacts the body, and a sensor or the like that can detect the body contact can be used as a switch.

Next, the operation of the on / off switch 30 according to the present invention.

Once the plug 18 is plugged into an external power supply terminal (not shown), the on / off switch 30 is in a standby state for applying power to the light emitting unit 20. In this state, When the treatment unit body 10 is inserted into the affected part such as the neck, shoulder, knee, etc., as shown in FIG. 4, the button of the on / off switch 30 is pressed together while the skin contact unit of the treatment unit body 10 is pressed. As a result, the on / off switch 30 is turned “on” from “off” to apply power to the power connector 24 of the light emitting unit 20.

When power is applied to the power connector 24, the therapeutic light is irradiated from the plurality of laser diodes 26 by wires 29 connected to each other between the power connector 24.

Accordingly, the low power laser irradiator according to the present invention treats only when the therapeutic light is intensively irradiated to a specific part of the affected part, that is, when the seating hole 12 of the treatment device body 10 is inserted into the affected part such as the neck, shoulder, or knee. The molten light can be irradiated.

On the contrary, when the treatment body 10 is detached from the state fitted to the affected part, the pressed part of the skin contact part returns to its original state, and the pressure holding the button of the on / off switch 30 disappears. The on / off switch 30 goes from the "on" state to the "off" state, and cuts off the power applied to the light emitting unit 20 again.

Therefore, when the seating hole 12 of the treatment device body 10 is separated from the affected part of the human being, the power applied to the light emitting part 20 is automatically cut off, so that the treatment light is no longer in the laser diode 26. By not being irradiated, when the low power laser irradiator is not used, it is possible to protect the eyes of the user and others while preventing unnecessary power consumption.

In particular, when the heating wire insulation member 13 of the treatment device body 10 is used as a material with high elasticity, when the fitting hole 12 is inserted into the affected part, it can be firmly adhered to the skin contact area while giving less pressure. In addition, the operation of the on / off switch 30 can be further ensured.

In addition, the on / off switch 30 'may be installed and used to be built into the body of the treatment device.

Thus, even when the on / off switch 30 'is provided with one or more on / off switches 30' by the same operation as the former, the light for treatment is irradiated from the light emitting part 20 '. To be cracked down.

That is, when a human body is in contact with any one of the plurality of on / off switches 30 'and a pressure is applied, the on / off switch 30' is pressed to be in an “on” state so that the light emitting unit 20 ' The therapeutic light is irradiated from the laser diode 26 '. At this time, if the on / off switch 30 'is appropriately installed in parallel in a plurality, as shown in Figure 8, even if any one of the plurality of on / off switch 30' is in contact with the human body The laser diode can be operated simultaneously.

On the contrary, when the pressure applied to the on / off switch 30 ', ie, the person releases while holding the on / off switch 30', the on / off switch 30 'is in the "on" state. In the " off " state, power applied to the light emitting part 20 'is cut off so that the therapeutic light is no longer irradiated from the light emitting part 20'.

Therefore, when the low power laser irradiator having the plurality of light emitting parts 20 'is used, the on / off switch 30' is turned "on" so that the treatment light is irradiated and used for the treatment. When the laser irradiator is not used, the on / off switch 30 'is turned “off” so that the therapeutic light is no longer irradiated to prevent waste of power and protect the eyes of the user and others. do.

On the other hand, in the treatment apparatus body 10 ′ as shown in FIG. 5, the light emitting portion 20 ′ and the on / off switch 30 ′ are appropriately arranged in plural numbers (see FIG. 9), whereby the human body is in contact with each other. Only the laser diode 26 'of the light emitting unit 20' may be operated.
