Description

Portable Phototherapy Device for Skin Care

The present invention relates to a portable skin light therapy device, and more particularly, to a portable skin light therapy device comprising a touch sensor for detecting contact with the skin.

Acne, which is one of the representative skin diseases, appears mainly in men and women before and after puberty, and hormones that begin to be released during puberty stimulate sebaceous glands to enlarge sebaceous glands and promote sebum secretion. This acne is an inflammatory disease of the hair sebaceous glands, and the occlusion of hair follicles causes the formation of a scrim (i.e., black or white cotton) consisting of sebum, keratin and microorganisms.

These acne should be treated when the inflammation of the sebaceous glands attached to the hair follicles is large, perfect treatment is not easy, and if you are concerned, it is a problem that can easily spread to larger diseases.

It is common to squeeze acne with nails, but this is unsanitary, and the germs are removed and removed, and only a part of the acne is removed and many parts remain to enlarge the inflammation, leaving scars that are very likely to cause sequelae.

Therefore, it is desirable to treat acne by surgical methods (treatment) and the like, and several acne treatment devices for use in such surgical methods have been developed. For example, as a conventional technique for removing acne, an acne treatment device using a mechanical treatment method of inhaling acne, which is made in the form of a squeeze device or a syringe, which is simply configured in a cylinder or a ring shape, has been developed.

In addition, when the basic luminescence duration is the time set in the previous skin treatment, the luminescence duration is maintained until further correction is made.

After setting the light emission duration, when the skin treatment unit 120 contacts the skin 200, the touch detection sensor 128 transmits a contact signal to the control unit, and the control unit emits light 125 of the light source unit 124. ) To start the treatment of the skin 200. In addition, when treatment starts, countdown of the luminescence duration begins.

When the entire touch detection sensor 128 does not detect contact with the skin 200, light emission from the light source unit 124 is stopped, and countdown of the light emission duration is stopped.

If the contact with the skin is detected within a predetermined time (for example, 1 minute) after the light emission of the light source unit 124 is stopped, the countdown which has been stopped is restarted with the light emission of the light source unit 124 again.

If a predetermined time is exceeded or the setting button 117 of the control box 115 is pressed after the light emission is stopped, it is again selected as a 'default light emission duration' value and becomes an operation standby state.

On the other hand, when the standby operation state for a certain time automatically the power of the portable skin light therapy device 100 is changed to the off state.
