Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a photon therapy device with temperature protection that enables real-time temperature detection of the photon therapy head. Background Technology
[0002] Photobiological modulation therapy is a non-invasive therapeutic technique that uses photon energy of specific wavelengths (600-1000nm) to regulate cell metabolism. It activates mitochondrial cytochrome C oxidase, promoting ATP synthesis and demonstrating clear clinical efficacy in relieving pain, inhibiting inflammation, and accelerating tissue repair. This therapy has been widely used clinically to treat inflammation on the human body surface. Currently, photon therapy devices used clinically are mainly divided into two types: fixed irradiation type, where the light source is kept at a certain distance from the wound, and the light source is irradiated onto the wound through a lens; and direct irradiation type, where the light source is transmitted through optical fiber and directly irradiates the wound. Fixed irradiation type photon therapy devices have many drawbacks. For example, due to severe backscattering of the light source after passing through the lens, even with strict control of the irradiation distance, it is impossible to ensure the uniformity of the light spot, the light power density, and the precise light treatment dose at the wound site. This results in the treatment beam's penetration depth and saturation in inflamed tissue failing to meet the requirements of phototherapy, leading to inconsistent treatment effects. While direct irradiation offers significant improvements in light uniformity, light power density, and therapeutic efficacy, the close proximity of the treatment component to the wound makes it highly susceptible to burns and secondary damage if the component reaches a high temperature. This is particularly true for photobiological therapy targeting mucosal inflammation, burns, scalds, skin damage from radiotherapy and chemotherapy, and skin inflammation in children and the elderly, placing even higher demands on the temperature sensitivity and safety of the treatment component.

[0029] Please see Figure 1 This utility model provides a photon therapy device with temperature protection, including a photon therapy component 100 and a main unit 200.
[0030] The photon therapy assembly 100 incorporates flexible optical fibers and fluorescent optical fibers. At one end of the photon therapy assembly 100 is a photon therapy head 101 woven with transparent braided yarn as the weft and flexible optical fibers as the warp, with a fluorescent optical fiber temperature sensor 102 woven into the photon therapy head 101. At the other end of the photon therapy assembly 100, the flexible optical fiber is fixedly connected to a therapy light connection device 103, and the fluorescent optical fiber is fixedly connected to a fluorescence excitation light connection device 104 and a fluorescence connection device 105, respectively.
[0031] The host 200 includes a main control module 201, a treatment light source module 202, a fluorescence signal detection module 203, a fluorescence excitation light source module 204, a power supply module 205, a display module 206, and a photon therapy component connection module 207.
[0032] The photon therapy component connection module 207 includes a fluorescence excitation light source device fixing sleeve 208, a fluorescence device fixing sleeve 209, and a therapy light source device fixing sleeve 210.
[0033] The therapeutic light source device fixing sleeve 210 contains a therapeutic light source output end fixing device and a therapeutic light source coupling device. The therapeutic light source module 202 is connected to the therapeutic light connection device 103 through the therapeutic light source device fixing sleeve 210, realizing the therapeutic light path connection between the host 200 and the photon therapy component 100.
[0034] The fluorescent excitation source device fixing sleeve 208 contains a fluorescent excitation source output end fixing device and a fluorescent excitation source coupling device. The fluorescent excitation source module 204 is connected to the fluorescent excitation light connection device 104 through the fluorescent excitation source device fixing sleeve 208, realizing the fluorescent excitation light optical path connection between the host 200 and the photon therapy component 100. The light beam emitted by the fluorescent excitation source module 204 emits fluorescence from the excitation fluorescence fiber temperature sensor 102.
[0035] The fluorescent device fixing sleeve 209 houses a temperature detection module fluorescence input terminal fixing device and a fluorescence coupling device. The fluorescence signal detection module 203 is connected to the fluorescence connection device 105 through the fluorescent device fixing sleeve 209, realizing the fluorescence optical path connection between the host 200 and the photon therapy component 100. The fluorescence signal detection module 203 is used to receive the fluorescence beam emitted by the fluorescence fiber temperature sensor 102, convert it into a photoelectric signal, and transmit it back to the main control module 201.
[0036] The fluorescence coupling device is equipped with a fluorescence filter to filter out the treatment beam emitted by the treatment light source module 202 transmitted by the fluorescence fiber temperature sensor 102 of the photon treatment head 101.
[0037] The fluorescent excitation light source device fixing sleeve 208, the fluorescent device fixing sleeve 209, and the therapeutic light source device fixing sleeve 210 are independent and run in parallel to avoid mutual interference between the light paths.
[0038] The main control module 201 is connected to the treatment light source module 202, the fluorescence signal detection module 203 and the fluorescence excitation light source module 204 respectively. The main control module 201 is used to control the fluorescence excitation light source module 204 to emit a fluorescence excitation beam and receive the photoelectric signal from the fluorescence signal detection module 203. Based on the internal program logic, the main control module 201 adjusts the light output power of the treatment light source module 202 accordingly.
[0039] The power supply module 205 supplies power to the main control module 201, the therapeutic light source module 203, the fluorescence signal detection module 203, the fluorescence excitation light source module 204, and the display module 206, respectively.
[0040] In this embodiment, the display module 206 is a serial port touch screen, which communicates with the main control module 201 via a serial port.
[0041] Working principle: During operation, the operator selects the treatment time and intensity through the preset values on the touch serial port screen of the display module 206. After the treatment time and intensity are selected, the display module 206 communicates with the main control module 201 through serial communication.
[0042] The main control module 201 controls the treatment light source module 202 to emit a treatment beam, which is coupled through the treatment light source coupling module of the treatment light source device fixing sleeve 210 and transmitted to the photon treatment head 101 through the treatment light connection device 103.
[0043] During the operation of the photon therapy device, the main control module 201 controls the fluorescence excitation light source module 204 to emit a fluorescence excitation beam according to the internal program. The beam is coupled through the fluorescence excitation light source coupling module of the fluorescence excitation light source device fixing sleeve 208 and transmitted to the fluorescence fiber optic temperature sensor 102 through the fluorescence excitation light connection device 104.
[0044] The fluorescent fiber optic temperature sensor 102 emits fluorescence, which, after reflection, passes through the fluorescent connection device 105, the fluorescent coupling device of the fluorescent device fixing sleeve 209, and the treatment beam is filtered out by a fluorescent filter before being transmitted to the fluorescent signal detection module 203. The fluorescent signal detection module 203 converts the received optical signal into an electrical signal and transmits it back to the main control module 201. The main control module 201 performs logical judgment on the electrical signal received from the fluorescent signal detection module 203 according to its internal program. If the electrical signal value is higher than a preset value, the main control module 201 reduces the current output of the treatment light source module 202 according to the preset program, thereby controlling the light output power of the treatment light source module 202. When the electrical signal value of the fluorescent signal detection module 203 is lower than the preset value, the current output value of the treatment light source module 202 is maintained. If the main control module 201 reduces the current output of the treatment light source module 202 according to the preset program, but the electrical signal of the fluorescent signal detection module 203 is still higher than the preset value, the main control module 201 will stop the light output of the treatment light source module 202 and display an alarm program on the display module 206.
[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way.
