The first figure is a system diagram of a preferred embodiment of the present invention.

In the following, the second preferred embodiment of the present invention will be further described in detail with reference to the following figures: Referring to the first figure, the temperature of the thermal therapy area of the phototherapy apparatus 1 of the preferred embodiment of the present invention is detected. The feedback module 10 is a conventional medical device which is capable of emitting laser or pulsed light to illuminate the skin, thereby obtaining medical and cosmetic effects, and the composition thereof is a conventional skill, which is not described herein, and generally includes a laser mechanism (not shown), an illumination head 12 and a control unit 14 and the like, a laser or pulse light is emitted from the illumination head 12 to illuminate the dermis layer of the human skin, and the control unit 14 controls the illumination head. 12, the transmission power, operation, the thermal detection zone temperature detection feedback module 10 is electrically connected to the laser or pulsed light irradiation head 12 and the control unit 14; the invention is characterized by further comprising: a non-contact temperature The detecting device 16 is a conventional infrared non-contact temperature measuring sensor, which is disposed in a phototherapy device corresponding to a laser or a pulsed light-radiating region (the area corresponding to the skin of the illuminating head 12) for detecting thermal photos. Actual leather in the area Layer temperature.

A feedback unit 18 is electrically connected to the non-contact temperature detecting device 16 and the control unit 14, and can be a computing program software or a control chip.

Therefore, the features and functions of the thermal detection zone temperature detecting feedback module 10 of the phototherapy device of the present invention are as follows: when the phototherapy device is in operation, the non-contact temperature detecting device 16 can detect the laser or the pulsed photothermal illumination region. The actual temperature of the dermis layer (between 0.3 mm and 3 mm) is transmitted to the feedback unit 18, and the feedback unit 18 can calculate and determine the actual dermis temperature and the preset temperature before the operation of the phototherapy device. The difference is that if the difference is positive, the emission power of the laser or pulsed light irradiation head 12 is lowered, and if the difference is negative, the emission power of the laser or pulsed light irradiation head 12 is increased, of course, if There is no difference between the actual dermis temperature and the preset temperature, that is, continuous operation with preset laser or pulsed optical power.

In particular, in the case of medical beauty, the use of laser or pulsed light to stimulate the dermis to proliferate collagen, the temperature range of about 45 to 60 ° C. When the doctor or the operator operates the phototherapy device, the preset temperature is 50 ° C (the predetermined temperature of the dermis layer of the skin is irradiated by the laser or the predetermined power of the pulsed light), and the actual dermis temperature detected by the non-contact temperature detecting device 16 is At 40 ° C, the feedback unit 18 can determine that the difference between the actual dermis temperature and the preset temperature is negative (40-60 = -20), then the control unit 14 can cause the laser mechanism to increase the laser or pulsed light irradiation. The transmit power of the head 12 causes the actual dermis temperature detected by the non-contact temperature detecting device 16 to rise to approach 50 ° C. Conversely, the laser mechanism is caused to reduce the emission power of the laser or pulsed light head 12 The non-contact temperature detecting device 16 detects the actual dermis layer The temperature can be lowered to approach 50 ° C, and the compensation effect of the temperature difference is obtained.

If the actual dermis temperature is less than the preset temperature, the emission power of the laser or pulsed light is increased, and the difference between the actual dermis temperature and the preset temperature is made. Falling within this temperature range, the operation of the feedback unit 18 and the control unit 14 and the illumination head 12 described above, the phototherapy device can be automatically performed.

It can be seen from the above that the present invention further provides a method for controlling the dose of the illumination area of the phototherapy device, which is to detect the actual dermis layer of the skin area irradiated by the laser or the pulsed light of the phototherapy device by means of non-contact temperature detection. The temperature (using the non-contact temperature detecting device 16), and then comparing the actual dermis temperature with the preset temperature (using the feedback unit 18), if the actual dermis temperature is different from the preset temperature, the feedback unit 18 transmits a feedback signal to The control unit 14 enables the control unit 14 to adjust the emission power of the laser or pulsed light to obtain a stable dermal layer laser or pulsed light irradiation dose.
