Description

Technical Field

[0001] The present invention relates to an electrotherapy device; in particular, to an electrotherapy device with a phototherapy function. Background Art

[0002] Electrotherapy is a common treatment method in physical therapy. A stimulation signal is generated by an electrotherapy device, and then the stimulation signal is applied to the skin of a living organism through the electrodes of the electrotherapy device. The stimulation signal is then transmitted into the body to stimulate muscle contraction and blood vessel dilation, thereby relieving muscle soreness and promoting blood circulation in the body, while achieving therapeutic effects such as dredging meridians.

[0003] In addition, phototherapy is usually performed before an electrotherapy session. Phototherapy involves emitting light from a phototherapy device onto the skin of a living organism, allowing the light to irradiate the skin and generate heat, thereby activating the blood circulation in the body. After the phototherapy is completed, the electrotherapy session is then performed to enhance the therapeutic effect of the electrotherapy.

[0004] However, conventional phototherapy and electrotherapy treatments are usually performed in stages, with phototherapy completed first and then electrotherapy. This results in a very time-consuming and time-consuming treatment course, as well as the need for both devices, which increases hardware costs. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide an electrotherapy device, wherein the output module has the functions of both phototherapy and electrotherapy.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an electrotherapy device for connecting a power source and a living organism, wherein the electrotherapy device includes a driving module, a conversion module and two output modules, wherein the driving module is electrically connected to the power source and converts the power of the power source into a driving signal; the conversion module has an input port and an output port, the input port is electrically connected to the driving module and receives the driving signal, the output port includes two output terminals, the conversion module converts the driving signal into a stimulation signal with positive and negative potential changes and outputs it from the two output terminals of the output port; each of the output modules includes a main body, an electrode and a generator. A light module, wherein each of the main bodies has an application side, each of the electrodes and each of the light-emitting modules is arranged on each of the main bodies, and each of the electrodes protrudes from the application side of each of the main bodies, and the light emitted by each of the light-emitting modules is directed toward the outside of the application side of each of the main bodies; each of the light-emitting modules is electrically connected to each of the output ends of the output port, and each of the electrodes is electrically connected to each of the light-emitting modules; wherein, when the two electrodes contact the organism, the application side faces the organism, the stimulation signal is applied to the organism via the two light-emitting modules and the two electrodes, and each of the light-emitting modules is driven by the stimulation signal to emit light to illuminate the organism.

[0007] The effect of the present invention lies in that through the design of the electrotherapy device, the light-emitting module and the electrode are arranged together on the main body, so that the stimulation signal drives the light-emitting module to emit light to illuminate the skin of the organism, thereby activating the blood circulation in the body, and at the same time, the stimulation signal is transmitted to the skin through the electrode, which can not only relieve muscle soreness, but also accelerate the blood circulation in the body and dredge the meridians, so that each of the output modules has the functions of phototherapy and electrotherapy at the same time, and achieves the purpose of shortening the entire treatment course of phototherapy combined with electrotherapy, and reducing hardware costs.

[0045] In order to explain the present invention more clearly, preferred embodiments are given and described in detail with reference to the accompanying drawings. Figure 1 The electrotherapy device 100 of the first preferred embodiment of the present invention is shown. The electrotherapy device 100 is connected to a power source 400 and a living organism 500, such as a human body. The electrotherapy device 100 includes a driving module 10, a conversion module 20, and two output modules 30.

[0046] like Figure 1 As shown, the driving module 10 is electrically connected to the power supply 400 and converts the power of the power supply 400 into a driving signal. The driving signal can be a current or voltage signal. In this embodiment, it is a current signal. The circuit of the driving module 10 can refer to patent number TWI643646 "Cutaneous Nerve Stimulator Group" and will not be repeated here.

[0047] like Figures 1 to 3As shown, the conversion module 20 has an input port 21 and an output port 22. The input port 21 includes two input terminals 21a and 21b. The input port 21 is electrically connected to the driving module 10 and receives the driving signal. The output port 22 includes two output terminals 22a and 22b. The conversion module 20 includes a full-bridge switching circuit 23 and a control circuit 24. The full-bridge switching circuit 23 includes a first transistor 231, a second transistor 232, a third transistor 233, and a fourth transistor 234. The first transistor 231, the second transistor 232, the third transistor 233, and the fourth transistor 234 respectively have a first terminal n1, n4, n7, n10, a second terminal n2, n5, n8, n11, and a third terminal n3, n6, n9. , n12, the first end n1 of the first transistor 231 is electrically connected to the input end 21a of the input port 21, the third end n3 of the first transistor 231 is electrically connected to the first end n4 of the second transistor 232 and the output end 22a of the output port 22, the third end n6 of the second transistor 232 is electrically connected to the third end n12 of the fourth transistor 234, the first end n7 of the third transistor 233 is electrically connected to the input end 21a of the input port 21, the third end n9 of the third transistor 233 is electrically connected to the output end 22b of the output port 22, the first end n10 of the fourth transistor 234 is electrically connected to the third end n9 of the third transistor 233, and the third end n12 of the fourth transistor 234 is electrically connected to the input end 21b of the input port 21. The control circuit 24 is electrically connected to the second ends n2, n5, n8, and n11 of the first transistor 231, the second transistor 232, the third transistor 233, and the fourth transistor 234. The control circuit 24 may include a microcontroller. The control circuit 24 is used to generate multiple switching signals S1, S2, S3, and S4 to respectively control the second ends n2, n5, n8, and n11 to form a timing phase conduction, thereby the conversion module 20 converts the driving signal into a stimulation signal with positive and negative potential changes and outputs it from the two output ends 22a and 22b of the output port 22.

[0048] More specifically, the control circuit 24 controls the output of high-level switching signals S1 and S4 to the second terminals n2 and n11 of the first transistor 231 and the fourth transistor 234, thereby turning on the first transistor 231 and the fourth transistor 234, and outputs low-level switching signals S2 and S3 to the second terminals n5 and n8 of the second transistor 232 and the third transistor 233, thereby turning off the second transistor 232 and the third transistor 233. In this case, the stimulation signal is a positive potential. The control circuit 24 controls the output of low-level switching signals S1 and S4 to the second terminals n2 and n11 of the first transistor 231 and the fourth transistor 234, thereby turning off the first transistor 231 and the fourth transistor 234, and outputs high-level switching signals S2 and S3 to the second terminals n5 and n8 of the second transistor 232 and the third transistor 233, thereby turning on the second transistor 232 and the third transistor 233. In this case, the stimulation signal is a negative potential. In this embodiment, a zero potential is included between the positive potential and the negative potential. The control circuit 24 controls the output of low-level switching signals S1, S2, S3, and S4 to the second terminals n2, n5, n8, and n11 of the first transistor 231 through the fourth transistor 234, thereby turning off the first transistor 231 through the fourth transistor 234, thereby rendering the stimulation signal at zero potential. In one embodiment, there may be no zero potential interval between the positive potential and the negative potential. That is, the positive potential may be directly converted to the negative potential, and the negative potential may be directly converted to the positive potential.

[0049] In this embodiment, the first transistor 231, the second transistor 232, the third transistor 233 and the fourth transistor 234 are bipolar junction transistors, each of the first terminals n1, n4, n7, and n10 is a collector of the bipolar junction transistor, each of the second terminals n2, n5, n8, and n11 is a gate of the bipolar junction transistor, and each of the third terminals n3, n6, n9, and n12 is an emitter of the bipolar junction transistor. In other embodiments, the first transistor 231, the second transistor 232, the third transistor 233 and the fourth transistor 234 can be a metal oxide semiconductor field effect transistor.

[0050] Please refer again Figure 1 and Figure 4In this embodiment, each output module 30 is implemented as an electrotherapy patch and includes a body 31, an electrode 32, and a light-emitting module 33. Each body 31 has an application side 311, and each application side 311 of each body 31 has a surface 311a. Each electrode 32 and each light-emitting module 33 are disposed on each body 31, and each electrode 32 protrudes from the application side 311 of each body 31. More specifically, each electrode 32 comprises, from top to bottom, a conductive layer 321 and a conductive adhesive layer 322. Each conductive layer 321 is bonded to the surface 311a of the application side 311 of each body 31, and each conductive adhesive layer 322 is bonded to each conductive layer 321. The area of ​​each conductive adhesive layer 322 is no less than that of each conductive layer 321, ensuring that each output module 30 adheres to the skin of the biological subject 500 and does not easily fall off. Each electrode 32 has a light-transmitting portion P1 formed between each conductive layer 321 and each conductive adhesive layer 322. Each light-emitting module 33 is electrically connected to the output ends 22a, 22b of the output port 22. Each light-emitting module 33 is located above each light-transmitting portion P1. Light emitted by each light-emitting module 33 passes through each light-transmitting portion P1 and is directed toward the exterior of the application side 311 of each body 31. Each of the light-emitting modules 33 includes a first diode 331 and a second diode 332. The first diode 331 and the second diode 332 respectively have an anode and a cathode. The anode of the first diode 331 is electrically connected to one of the output ends 22a, 22b and the cathode of the second diode 332. The cathode of the first diode 331 is electrically connected to the electrode 32, and the anode of the second diode 332 is electrically connected to the electrode 32.

[0051] In this embodiment, the first diode 331 and the second diode 332 are both light emitting diodes. The light emitting diodes may be, for example, infrared diodes, laser diodes, or diodes that can emit light of a specific color.

[0052] In this embodiment, the conductive layer 321 may be made of a metal layer or a conductive composite material containing metal or carbon. The light-transmitting portion P1 is a light-transmitting hole. In other embodiments, the light-transmitting portion P1 may be made of a light-transmitting material, such as a material that is infrared-transmissive.

[0053] During use, the application side 311 of the body faces the subject 500, and the two electrodes 32 contact the skin of the subject 500. The electrodes 32 of each output module 30 transmit the stimulation signal to the subject 500, with the subject 500 acting as a resistor to form a conductive path. For example, when the electrodes 32 contact acupuncture points, electronic acupuncture can be performed; when the electrodes 32 contact a sore area, electrical stimulation can be provided to relieve the pain.

[0054] The driver module 10 receives power from the power source 400 and transmits the drive signal to the input port 21 of the conversion module 20. The control circuit 24 controls the full-bridge switching circuit 23 to convert the drive signal into the stimulation signal with positive and negative potential variations, and outputs the signal through the output port 22 to the two output modules 30. The stimulation signal is applied to the skin of the biological subject 500 via the two light-emitting modules 33 and the two electrodes 32, respectively, to transmit light and current signals. Because the first diode 331 and the second diode 332 of each output module 30 are connected in opposite directions, when the stimulation signal is positive, one of the first diode 331 and the second diode 332 of each output module 30 conducts forward and emits light; when the stimulation signal is negative, the other of the first diode 331 and the second diode 332 of each output module 30 conducts forward and emits light. In other words, when the stimulation signal is positive or negative, the light-emitting modules 33 of both output modules 30 emit light. This allows for the simultaneous effects of phototherapy and electrotherapy.

[0055] Please refer to Figure 5 In a second preferred embodiment of the present invention, the output module 40 can be a rod-shaped embodiment, and each electrode 42 is a metal rod protruding from each surface 411a to the outside. Through one end of the metal rod of the electrode 42 contacting the skin, the stimulation signal is transmitted into the body. Each light-emitting module 33 is disposed around each electrode 42, and each surface 411a has at least one light-transmitting portion P2. In this embodiment, the at least one light-transmitting portion P2 is a light-transmitting hole and is correspondingly disposed below each light-emitting module 33. Each light-emitting module 33 transmits light through the light-transmitting hole below, which can also achieve the effect of simultaneous phototherapy and electrotherapy. Because each electrode 42 is a metal rod, it can directly contact the acupuncture points to achieve the purpose of electronic acupuncture. In other embodiments, the light-transmitting portion P2 can be made of a light-transmitting material, such as a material that is transparent to infrared rays.

[0056] Please refer to Figure 6The third preferred embodiment of the present invention is shown as an electrotherapy device 300. This embodiment has substantially the same structure as the first embodiment, differing in that the first diode 531 or the second diode 532 of each output module 50 can be replaced with a non-luminescent diode. Therefore, the electrotherapy device 300 of this embodiment can not only perform both light therapy and electrotherapy simultaneously, but also adjust the timing of the intermittent illumination of each light-emitting module 53 as needed. In other embodiments, the second diode 532 can be replaced with a non-luminescent diode as needed. By replacing only one of the first diode 531 and the second diode 532 of each output module 50 with a non-luminescent diode, the intermittent illumination of the light-emitting module 53 can be achieved. That is, when the stimulation signal is positive or negative, only one of the light-emitting modules 53 of the two output modules 50 will illuminate, resulting in the two light-emitting modules 53 illuminating in turn.

[0057] In summary, the electrotherapy device of the present invention includes the light-emitting module and the electrodes through each of the output modules, so that the stimulation signal drives the light-emitting module to emit light to illuminate the skin of the organism, thereby activating blood circulation in the body, and at the same time, the stimulation signal is transmitted to the skin through the electrodes. This not only relieves muscle soreness, but also serves as electronic acupuncture. It is worth mentioning that, in conjunction with phototherapy, it can also accelerate blood circulation and dredge meridians in the body, achieving the simultaneous efficacy of phototherapy and electrotherapy by each of the output modules, shortening the entire treatment course of phototherapy combined with electrotherapy, and reducing hardware costs.
