Thermal detection zone temperature detection feedback module of phototherapy equipment

This creation department is related to phototherapy equipment, in more detail, it refers to a temperature-sensing zone temperature detection feedback module of a phototherapy device and a radiation dose adjustment method in a thermal illumination area.

According to the rapid development of medical beauty technology, laser/pulse phototherapy has become the most popular new trend in skin beauty. Laser phototherapy uses light wave absorption to produce plaque damage and photothermal induction, which enhances melanin metabolism and stimulates the dermis. Collagen hyperplasia and then achieve the function of rejuvenation and anti-aging, so it can remove spots, blemishes, wrinkles, acne, and revitalize the skin, thus attracting many light-aged and mature-aged beauty experiences, and is fashionable.

At present, the most common types of laser phototherapy are the shuttle laser and the soft laser. Softening laser is a non-invasive laser cosmetic technology. According to different light wavelengths, it can be divided into toner laser and commonly known white porcelain doll laser. White porcelain doll laser uses wavelength. Deep into the dermis layer, stimulate the dermal tissue, and shake the melanin, in order to effectively remove the phenomenon of uneven skin tone, and then whiten the skin, to achieve the effect of pigmentation spots and improve melanin.

The operation mode of the conventional laser phototherapy device is controlled by a physician to irradiate the laser head, and the head is moved in the illumination area by manual or automatic control, and the skin is irradiated with laser light energy for cosmetic treatment. The effect of laser phototherapy is affected by the energy control and light depth control of phototherapy equipment. For the sake of safety and stability, the current phototherapy equipment can be set by computer to set the depth and range of illumination, and the treatment depth can be fixed quickly and safely. There is no side effect of anti-black.

Although the conventional phototherapy device can be set by the computer to set the depth and range of the irradiation, in fact, when the laser light is irradiated to the skin, the temperature of the skin surface and the dermis layer often differs, and the laser phototherapy mainly stimulates the collagen proliferation of the dermis layer. If the actual light temperature of the dermis layer is lower than the computer set value, it will obviously affect the phototherapy effect. Therefore, some manufacturers have developed phototherapy equipment with temperature detection, such as US8439405, US6413255, China Republic of China M246583, Public No. 200831152, China CN90107543 .4, CN90107189.7, CN90107456.X, CN200510053757.8, CN201110376475.7 and CN201310113506.9 and other patents.

Although the US patent discloses a technique for exposing skin temperature sensing, the temperature sensing portion is combined with the pin inserted into the dermis layer, which is an invasive design, and the temperature sensing of the relevant laws of the Republic of China and China is contact type. The design is still in line with the current non-contact development of phototherapy equipment.

In view of this, the creator has been engaged in related industries for many years. The research and development and production experience, in-depth study of the problems faced by the current, after long-term efforts to research and trial, after all, research and development of this new type.

The main purpose of this creation is to provide a thermal detection zone temperature detection feedback module for phototherapy equipment, which can automatically adjust the emission power of laser or pulsed light to compensate the skin by means of non-contact detection of the actual dermis temperature. The difference between the temperature of the surface and the dermis layer is convenient for the physician to increase the irradiation dose or reduce the dose of the radiation as the patient's treatment course, and obtain a stable dermal layer laser or pulsed light irradiation dose, which can perform accurate and stable cosmetic treatment for the treatment area. To ensure the effectiveness of cosmetic treatment, it is of great commercial value.

The reason is that, in order to achieve the above purpose, the present invention provides a thermal detection zone temperature detection feedback module of a phototherapy device, which can emit laser or pulsed light to illuminate the dermis layer of the skin, thereby obtaining medical and cosmetic effects.

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

In the following, a preferred embodiment of the present invention will be described in detail with reference to the drawings. As shown in the first figure, the temperature of the thermal therapy area of the phototherapy device 1 of the preferred embodiment is determined. 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 present 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. The control unit 14 can be built in the control unit 14 or separately disposed at a suitable part of the phototherapy device. Calculate and judge the actual temperature of the actual dermis layer in the hot-illuminated area and the operation of the phototherapy equipment One of the preset preset temperatures.

Therefore, the features and functions of the thermal detection zone temperature detecting feedback module 10 of the present phototherapy device are as follows: when the phototherapy device is in operation, the non-contact temperature detecting device 16 can detect the laser or pulsed photo-thermal 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 lower the laser or pulsed light head 12 The transmit power is such that the actual dermis temperature detected by the non-contact temperature detecting device 16 can be lowered to approach 50 ° C, and the compensation effect of the temperature difference is obtained.

Of course, the determination of the difference between the actual dermis temperature and the preset temperature before the operation of the phototherapy device by the feedback unit 18 is not limited to a positive or negative difference, and may be a temperature range (absolute value). That is, if the preset temperature before the doctor or operator operates the phototherapy device is 45 to 60 ° C (such as 52.5 ° C), the difference can also be set to 7.5 (the absolute value of 60-52.5 or 45-52.5) When the difference between the actual dermis temperature and the preset temperature is less than 7.5, it is not necessary to adjust the emission power of the laser or pulsed light irradiation head 12 (because the actual dermis temperature is not greater than 45 ° C, that is, less than 60 ° C, still in Stimulating the temperature range of collagen in the dermis layer, and when the difference between the actual dermis temperature and the preset temperature is greater than 7.5, the feedback unit 18 determines that the actual dermis temperature is greater or less than the preset temperature, the actual dermis layer The temperature is greater than the preset temperature, that is, the emission power of the laser or pulsed light is reduced. 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.

In summary, the thermal detection zone temperature detection feedback module of the phototherapy device provided by the present invention uses the actual dermis temperature of the non-contact temperature detecting device to determine the actual dermis temperature and the pre-determination by the feedback unit. The difference in temperature is set, so that the control unit can adjust the emission power of the laser or pulsed light, which can compensate for the difference between the temperature of the skin surface and the dermis layer, and is convenient for the physician to suffer from The dose of the irradiated dose or the dose of the irradiated dose judged by the treatment process can obtain a stable dermal layer laser or pulsed light irradiation dose, and can perform an accurate and stable cosmetic treatment process on the treatment area to ensure the beauty treatment effect, thereby improving the beauty treatment. The practical purpose of quality is of great commercial value.
