Description

Electrotherapy Device

The present invention relates to an electrotherapy device; in particular, to an electrotherapy device with phototherapy function.

Electrotherapy is a common treatment method in physical therapy. An electrotherapy device generates a stimulation signal, which is then applied to the skin of the organism through the electrodes of the electrotherapy device. The stimulation signal is transmitted into the body to stimulate muscle contraction and vascular dilation, thereby relieving muscle soreness and promoting blood circulation in the body, while achieving therapeutic effects such as dredging meridians.

In addition, phototherapy is usually used before electrotherapy. Phototherapy is to irradiate the skin of a living organism with light from a phototherapy device, so that the light can irradiate the skin and generate heat, thereby activating the blood circulation in the body. After the phototherapy is completed, electrotherapy is then carried out to enhance the therapeutic effect of electrotherapy.

However, conventional phototherapy and electrotherapy treatments are usually implemented in stages, with electrotherapy performed after phototherapy. As a result, a complete course of phototherapy and electrotherapy will take a lot of time and require both phototherapy and electrotherapy devices, which will increase hardware costs.

In view of this, the purpose of the present invention is to provide an electrotherapy device so that the output module has both the functions of light therapy and electrotherapy.

In order to achieve the above-mentioned purpose, the present invention provides an electrotherapy device for connecting a power source and a biological body, the electrotherapy device comprises 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 comprises a body, a Electrode and a light-emitting module, wherein each of the main bodies has an application side, each of the electrodes and each of the light-emitting modules are 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 to 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 irradiate the organism.

The effect of the present invention is that through the design of the electrotherapy device, the light-emitting module and the electrode are set together in the body, so that the stimulation signal drives the light-emitting module to emit light to irradiate 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 output module has the functions of light therapy and electrotherapy at the same time, and shortens the entire treatment time of light therapy combined with electrotherapy, and reduces the hardware cost.

Please refer to FIG. 1 and FIG. 4 again. In this embodiment, each output module 30 is an electrotherapy patch, and each output module 30 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 the 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. In more detail, each electrode 32 includes a conductive layer 321 and a conductive adhesive layer 322 from top to bottom, each conductive layer 321 is bonded to the surface 311a of the application side 311 of each body 31, each conductive adhesive layer 322 is bonded to each conductive layer 321, and the area of each conductive adhesive layer 322 is not less than the area of each conductive layer 321, so that each output module 30 adheres to the skin of the biological body 500 and will not fall off easily, and each electrode 32 has a light-transmitting portion P1, and each light-transmitting portion P1 is formed on each conductive layer 321 and each conductive adhesive layer 322. Each of the light-emitting modules 33 is electrically connected to each of the output ends 22 a and 22 b of the output port 22 . Each of the light-emitting modules 33 is located above each of the light-transmitting portions P1 . The light emitted by each of the light-emitting modules 33 passes through each of the light-transmitting portions P1 and shines toward the outside of the application side 311 of each of the main bodies 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 have an anode and a cathode respectively. The anode of the first diode 331 is electrically connected to one of the output terminals 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. Each of the electrodes 32 is electrically connected to each of the output terminals 22a, 22b of the output port 22 through the first diode 331 and the second diode 332 of each of the light-emitting modules 33.

In this embodiment, the first diode 331 and the second diode 332 are both light-emitting diodes, which may be infrared diodes, laser diodes, or diodes that can emit light of a specific color.

In this embodiment, the material of the conductive layer 321 can be a metal layer, a composite material containing metal or carbon that can be conductive, and the light-transmitting portion P1 is a light-transmitting hole. In other embodiments, the light-transmitting portion P1 can be made of a light-transmitting material, such as a material that can be penetrated by infrared rays.

When in use, the application side 311 of the body is used to face the biological body 500, the two electrodes 32 contact the skin of the biological body 500, and the electrodes 32 of each output module 30 transmit the stimulation signal to the biological body 500, and the biological body 500 forms a conductive path like a resistor. For example, when the electrode 32 contacts the location of the acupuncture point, electronic acupuncture can be performed; when the electrode 32 contacts the sore area, electrical stimulation can be performed to relieve the soreness.

The driving module 10 receives the power from the power source 400 and sends the driving 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 driving signal into the stimulation signal with positive and negative potential changes and output it from the output port 22 to the two output modules 30. The stimulation signal applies light and current signals to the skin of the biological body 500 via the two light-emitting modules 33 and the two electrodes 32 respectively. Since the first diode 331 and the second diode 332 of each output module 30 are reversely connected, 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. That is, when the stimulation signal is positive or negative, the light-emitting modules 33 of the two output modules 30 will both emit light. This achieves the effect of simultaneous phototherapy and electrotherapy.

Please refer to Figure 5. In a second preferred embodiment of the present invention, the output module 40 can be in a rod-like state. Each electrode 42 is a metal rod protruding from each surface 411a to the outside. One end of the metal rod of the electrode 42 contacts the skin to transmit the stimulation signal into the body. Each light-emitting module 33 is arranged around each electrode 42. 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 arranged below each light-emitting module 33. Each light-emitting module 33 transmits light through the light-transmitting hole below, and can also achieve the effect of simultaneous phototherapy and electrotherapy. Since 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 can be penetrated by infrared rays.

Please refer to FIG. 6 for an electrotherapy device 300 of the third preferred embodiment of the present invention. The structure of this embodiment is substantially the same as that of the first embodiment, except that the first diode 531 or the second diode 532 of each output module 50 can be replaced with a non-luminescent diode. Thus, the electrotherapy device 300 of this embodiment can not only perform light therapy and electrotherapy at the same time, The timing of the intermittent light emission of each light-emitting module 53 can also be adjusted according to the needs. In other embodiments, the second diode 532 can be replaced with a non-luminous diode according to the needs. As long as one of the first diode 531 and the second diode 532 of each output module 50 is replaced with a non-luminous diode, the effect of intermittent light emission of the light-emitting module 53 can be achieved. That is, when the stimulation signal is a positive potential or a negative potential, only one of the light-emitting modules 53 of the two output modules 50 will emit light, so that the two light-emitting modules 53 emit light in turn.

In summary, the electrotherapy device of this invention includes the light-emitting module and the electrode through each output module, so that the stimulation signal drives the light-emitting module to emit light to irradiate 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 be used as electronic acupuncture. What is more worth mentioning is that, with the cooperation of light therapy, it can also accelerate the blood circulation in the body and dredge the meridians, so that each output module has the effects of light therapy and electrotherapy at the same time, and shorten the entire treatment time of light therapy combined with electrotherapy, and reduce the hardware cost.

The above is only the preferred feasible embodiment of the present invention. Any equivalent changes made by applying the present invention specification and the scope of patent application should be included in the patent scope of the present invention.
