Above-mentioned microcontroller 50 more can be sent to control signal indicating device 55 and point out user present mode of operation with loudspeaker arrangement 52.Indicating device 55 can be a plurality of indication cressets to be formed, so that the operating state of user device for identifying is shinny as the indication cresset as various flickers, light quantity or the formula of rotating.Loudspeaker arrangement 52 is with the prompting of the sound to the operation of user do, as the sound information such as the warning sound, the on and off switch sound or plant failure of operation mistake.
Shown in Figure 6ly then be the step of photon dosage control method of the present invention, wherein if with the light energy of constant power according to establishing positions such as user skin, affected part, borrow irradiation time and the purpose that reaches adjusting photon dosage cooperating of irradiated area, step is as follows:
When dosage is regulated beginning, user can be adjusted wherein exposure dose by portable photon dosage adjusting device for medical beautifying disclosed in this invention, behind the activating power (step S61), need to judge exposure dose, the area and the photon energy that can need to shine are considered (step S63), borrow the irradiated area adjusting device of displacement or adjustment handheld apparatus of the present invention to change range of exposures (step S65), wherein this irradiated area adjusting device can be in-building type, this is fixing irradiated area, or the adjustable adjusting device of circumscribed, adjust irradiation time (step S67) by time control switch and irradiation mode again, and begin to shine user skin (step S69) with specific range.
Photon dosage shown in the present can photon irradiation power, irradiated area and irradiation time define, dosage equation such as D=(P*T)/A, wherein D is a photon dosage, P is a photon irradiation power, T is an irradiation time, it is photon energy that photon irradiation power is multiplied by irradiation time, and A is an irradiated area, so photon dosage is defined as the photon energy that unit are receives.
Figure 7 shows that one of embodiment of photon dosage adjusting device of the present invention, be to utilize the light source of specific medical beauty treatment usefulness to be arranged on the handheld apparatus 70, and the luminous/laser diode (LED) that uses the optical wavelength with specific medical beautifying use is as light source 73, on light source 73, can be provided with battery of lens 75, so as to can adequate focusing with light source in more among a small circle, make and be unlikely to influence emitted energy because of scattering, battery of lens 75 more can use the function as diffuser (diffuser), make irradiates light more uniform irradiation and complete covering skin, reach nondestructive medical application, as the purpose of figure stimulating hair growth.Change irradiation time, area and irradiated site to move this device during use, and with irradiation mode such as continuous or pulse modes to adjust photon energy, reach the effect that stimulates the growth of hair or biological tissue as regulating treatment doses (dosage).
It shown in the figure handheld apparatus 70 that a carry-on photon is regulated, its outward appearance device includes at least one luminous/laser diode light source 73, wherein light emitting diode is directly to encapsulate (Chip onBoard with chip, COB) or the fabrication techniques that directly encapsulates with the array type chip of another embodiment, except that strengthening the light energy, also can need with realistic medical treatment or beauty treatment so as in a device, producing the light source of a plurality of different wave lengths.The specific wavelength that has medical and beauty treatment really to imitate of above-mentioned light source 73 emissions is arranged at a side of handheld apparatus 70, is convenient to user and grips and operation, and light source 73 is provided with battery of lens 75 and helps light source and on average shine.Other has a photon irradiation area adjusting device 76 to be arranged on the direction of illumination of this light source 73, this irradiated area adjusting device 76 can be an external tubular device, change irradiated area so as to changing stack shell length, also can be fixedly in-building type design, promptly irradiated area is fixed.This figure is an example with irradiation hair tissue 701.
Figure 8 shows that the wear-type device sketch map of photon dosage adjusting device of the present invention, icon is a wear-type device 80, luminous/laser diode light source 73 is covered shape etc. with the zone to be arranged on this wear-type device 80 with having the adjustable position ability, the bald head patient can be as dressing the mode of hair band, wear in head to carry out medical treatment or health care by fixing band 82, and cooperate the light energy of adjusting to move this setting position along fixing band 82 in good time, also can be provided with diffuser on the light source 73 and make the even and increase coverage rate of irradiation, and avoid scorching hot phenomenon.
And Figure 9 shows that the device sketch map of medicated cap pattern, luminous/laser diode light source 73 can be arranged in the head-wearing device 90, the bald head patient carries out medical treatment or health care in the time of can being convenient to attach the names of pre-determined candidates, also can be provided with diffuser on the LED source 73 (dotted line is represented) and make the even and increase coverage rate of irradiation, and avoid scorching hot phenomenon.
The control of the dosage of photon irradiation of the present invention (Dosage) and the effect of medical and beauty treatment have great relation, if photon dosage may not have effect very little, if photon dosage is too many, then may have minus effect, and photon dosage is determined by power, irradiated area and the irradiation time of photon, thus the adjustment capability of the carry-on photon adjusting device of the present invention real be necessary function.
But the control circuit on luminous/laser diode light source mat device that this states is controlled its luminous behavior, as irradiation brightness, wavelength (color), Continuous irradiation, pulsed exposure, by a little less than the strong commentaries on classics or irradiation mode such as grow in strength.
Optical source wavelength of the present invention is defined as the optical wavelength of medical and beauty treatment purposes, with the adjusting that wherein can all be considered as medical and beauty treatment dosage for irradiation mode, irradiation time and the irradiated area etc. adjusted, and medical and beauty treatment or health-care effect comprise that as improving looks, whiten, promote bodily tissue growth, eyestrain etc., effect is not stated with this and exceeded.Please refer to American National aviation space agency delivered in 2002 " NASALight-Emitting Diodes for the Prevention of Oral Mucositis in Pediatric BoneMarrow Transplant Patients; Pp.319-324; Volume 20, Journal of ClinicalLaser Medicine ﹠amp; Surgery " the relevant light emitting diode of narrating is used for bone with the mucous paper in transplant patient prevention oral cavity.This paper accompanying drawing only provides reference and explanation usefulness, is not to be used for the present invention is limited.
In sum, the present invention is a kind of portable photon dosage adjusting device for medical beautifying and control method, be that light source with specific medical beauty treatment usefulness is arranged on the handheld apparatus, borrow the time and the area of this light source irradiation skin surface of control, regulate its photon dosage, reach the effect of various kinds medical and beauty treatment and health care, be rare invention article in fact, and usability, novelty and progressive on the tool industry, meet the application for a patent for invention condition fully, file an application in accordance with the law, would like to ask detailed survey and grant this case patent, to ensure inventor's rights and interests.
But the above only is a preferable possible embodiments of the present invention, and is non-so promptly arrest limit claim of the present invention, and therefore the equivalent structure done of every utilization description of the present invention and icon content changes, and all is contained in the claim scope of the present invention.
