Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of therapeutic instruments, in particular to a thermo-thermal low-frequency therapeutic instrument with an automatic adjustment electric stimulation function. Background Art
[0002] Electrical stimulation therapy is an important part of rehabilitation treatment. It achieves the therapeutic effect by adhering electrodes to human skin and passing pulse current to stimulate nerves and muscles and increase cell activity.
[0003] However, most current therapeutic devices rely on manual operation, primarily relying on the operator's accumulated experience. For example, before electrostimulation therapy, the skin surface needs to be cleaned locally to remove surface stains such as grease and sweat to prevent it from affecting the adhesion of the electrostimulation electrodes and to avoid corrosion of the electrostimulation electrodes themselves. The main cleaning method currently used is local wiping, which can easily cause local water residue, affecting local conductivity and thus reducing the conduction accuracy of the electrostimulation.
[0004] In addition, during muscle rehabilitation treatment, since individuals react differently to electric current stimulation of different intensities, the intensity of electrical stimulation cannot be automatically adjusted according to the individual's stimulation response. Once the stimulation is excessive, it will affect the rehabilitation effect, while less stimulation may easily lead to the inability to meet the intensity of rehabilitation training and prolong the recovery time. Summary of the Invention
[0005] The object of the present invention is to provide a low-frequency thermotherapy device with an automatic adjustment electrical stimulation function to solve the problems raised in the prior art.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] A thermothermal low-frequency therapeutic device with an automatically adjustable electrical stimulation function comprises a supporting frame, a skin cleaning device, an adjusting device and a control host. The control host is electrically connected to the adjusting device, the skin cleaning device is connected to the supporting frame, the skin cleaning device is connected to the adjusting device, and the adjusting device is connected to the supporting frame. The control host is used to control the output of the stimulation current.
[0008] The control host is used to provide low-frequency pulse current and provides multiple interfaces. During electrical stimulation treatment, the support frame serves as the main supporting base and is placed on the part of the human body to be stimulated. The skin cleansing device is used to locally clean the treatment part and provide warm airflow for local heating. After cleaning is completed, local electrical stimulation is performed through the adjustment device.
[0009] Furthermore, the skin cleansing device includes a drive motor, a skin cleansing roller and a gear. A drive cavity is provided on both sides of the bottom surface of the carrier frame. The drive motor is placed in the drive cavity. A gear is provided at the output end of the drive motor. A tooth groove is provided along the wall of the drive cavity. The gear and the tooth groove are meshed. The drive motor and the drive cavity are slidably connected.
[0010] The adjustment device includes a stimulation electrode and an adjustment cylinder. The adjustment cylinder is tightly connected to the drive motor housing. The output end of the adjustment cylinder is tightly connected to the stimulation electrode. The control host is used to power the stimulation electrode. The control host and the stimulation electrode form a stimulation circuit.
[0011] The driving motor is the main power source and is placed in the driving cavity. When the driving motor outputs torque, it can move laterally along the driving cavity through the meshing of gears and tooth grooves. The skin cleaning roller is made of flexible material and is used for local cleaning of the area to be electrically stimulated to prevent hair, sweat, etc. from affecting the effect of electrical stimulation. For example, when performing local cleaning of the waist, the two driving motors rotate in opposite directions to perform synchronous cleaning, thereby improving cleaning efficiency. After cleaning is completed, the adjustment cylinder is fixed to the driving motor housing and can move with the driving motor. The driving motor moves the adjustment cylinder to the area to be electrically stimulated, controls the adjustment cylinder to output displacement downward, and drives the stimulation electrode downward until it fits the area to be electrically stimulated. The host is controlled to output a pulse motor so that the stimulation electrode stimulates the muscle, causing the muscle to produce a tremor-like contraction, thereby conducting rehabilitation training and promoting functional recovery.
[0012] Furthermore, the skin cleansing device also includes a temperature control component, a power supply and a hot air pipe. The temperature control component includes electrode sheets. Electrode sheets are provided on both sides of the skin cleansing roller along the circumference. The electrode sheets are ring-shaped. Two adjacent electrode sheets and two terminal blocks of the power supply are electrically connected to form a detection circuit. The skin cleansing roller is provided with several air outlets along the circumference, and the hot air pipe is connected to the air outlet pipe.
[0013] When the skin cleansing roller cleans the electrically stimulated part, the hot air pipe sprays air to assist in cleaning the electrically stimulated part and improve the cleaning effect. The hot air pipe is connected to the hot and humid air flow, which can locally keep the electrically stimulated part warm. At the same time, after the cleaning is completed, the humidity of the skin surface is guaranteed to be within a certain range. The circuit electrically connected to the two electrode pieces and the power supply terminals is conducted by the moist air flow, so as to detect the local humidity of the electrically stimulated part. The detection circuit is electrically connected to the drive motor, and the speed of the drive motor is adjusted according to the measured current value. When the local humidity is low, the speed of the drive motor is reduced to increase the density of the moist and hot air flow here, thereby increasing the electrical conductivity of the skin here, ensuring the uniformity of the electrical stimulation during electrical stimulation, and improving the quality of rehabilitation.
[0014] Furthermore, a floating cavity is provided on the supporting frame, which carries water. The hot air pipe inlet is connected to the floating cavity pipeline. The temperature control component also includes an electric heating block, which is placed in the water body of the floating cavity. The control host supplies power to the electric heating block.
[0015] The first port of the control host is used to power the stimulation electrode, and the second port is used to power the electric heating block, which heats the water in the floating cavity. A pump body is set at the connection between the hot air pipe and the floating cavity to supply moist hot air flow, so that the moist hot air flow supply rate is uniform.
[0016] Furthermore, the adjustment device also includes an induction component, which is placed in the floating cavity. The induction component includes a suspension bowl and a conductive sheet. A number of brackets are provided on the outer ring of the suspension bowl. The brackets are in friction contact with the wall of the floating cavity away from the side of the suspension bowl. A cover is provided on the upper side of the suspension bowl. The suspension bowl contains conductive liquid. Two conductive sheets are provided. The lower ends of the two conductive sheets are inserted into the conductive liquid. The upper ends of the two conductive sheets are electrically connected to the power supply to form an adjustment circuit.
[0017] A sensing component is provided to detect the degree of muscle contraction. Initially, the levitating bowl rests within the floating chamber under the influence of the water's buoyancy. The conductive fluid within the bowl is horizontal, and the current in the regulation circuit, comprised of two conductive plates and a power supply, is stable. When the muscle begins to contract, the muscle fibers begin to thicken. The stimulating electrodes and the regulating cylinder drive the support frame to tilt, causing frictional contact between the chamber walls and the support. Static friction drives the levitating bowl to tilt, reducing the volume of the conductive fluid between the two conductive plates and, consequently, the number of ions involved in conduction. This reduces the current in the regulation circuit at the rated voltage of the power supply. The greater the degree of muscle contraction, the greater the tilt of the levitating bowl, and the lower the current in the regulation circuit. As the levitating bowl tilts, its center rises, and gravity overcomes the friction between the support and the chamber walls, returning it to its lowest point until the cover and the upper surface of the conductive fluid are level again, facilitating continuity testing.
[0018] Furthermore, the adjustment device also includes an auxiliary heating component, which includes an auxiliary heating resistor, a micro-cylinder and a conductive ring. The lower end of the floating cavity is provided with an adjustment groove, the upper end of the auxiliary heating resistor is inserted into the floating cavity, the lower end of the auxiliary heating resistor is placed in the adjustment groove, the micro-cylinder is placed in the adjustment groove, the output end of the micro-cylinder and the conductive ring are tightly connected, the conductive ring and the auxiliary heating resistor are in sliding contact, and the auxiliary heating resistor is connected in series with one end away from the micro-cylinder and one side of the conductive ring into the stimulation circuit;
[0019] When lowered: the micro-cylinder drives the conductive ring to move toward the side close to the micro-cylinder, and the resistance value of the auxiliary heating resistor connected to the stimulation circuit increases.
[0020] By setting up an auxiliary heating component to assist in generating moist and hot air flow, when performing electrical stimulation adjustment, if the stimulation intensity is large, the degree of muscle contraction will increase, thereby increasing the current value of the adjustment circuit. According to the detected current value, the input current of the micro-cylinder is controlled, and the micro-cylinder drives the conductive ring to move toward the side close to the micro-cylinder. The conductive ring and the auxiliary heating resistor are connected in series to the stimulation circuit. When the conductive ring slides toward the micro-cylinder, the resistance value of the auxiliary heating resistor connected to the stimulation circuit increases. When the output voltage of the control host is stable, the current of the stimulation circuit is instantaneously weakened, thereby reducing the stimulation of the stimulation electrode to the human body, avoiding excessive stimulation, and improving the electrical stimulation rehabilitation effect.
[0021] As an optimization, the micro-cylinder is electrically connected to a regulating circuit. The current detected by the regulating circuit determines the degree of muscle contraction under electrical stimulation, thereby controlling the micro-cylinder's start and stop, adjusting the current in the stimulation circuit, and automatically adjusting the intensity of electrical stimulation.
[0022] As an optimization, the floating cavity is spherical, which improves the stability of detection.
[0023] As an optimization, the outer arc of the bracket is set to match the arc of the floating cavity. This allows the bracket to make surface contact with the wall of the floating cavity, improving transmission efficiency and facilitating muscle tension detection.
[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the hot air pipe jets are used to assist in cleaning the area to be electrically stimulated, thereby improving the cleaning effect; the hot air pipe is connected to the moist hot air flow, which can locally insulate the area to be electrically stimulated; at the same time, after the cleaning is completed, the humidity of the skin surface is guaranteed to be within a certain range; the circuit electrically connected to the terminal of the two electrode sheets and the power supply is conducted through the moist air flow, thereby detecting the local humidity of the area to be electrically stimulated; the detection circuit is electrically connected to the drive motor, and the speed of the drive motor is adjusted according to the measured current value; when the local humidity is low, the speed of the drive motor is reduced, and the density of the moist hot air flow here is increased, thereby increasing the electrical conductivity of the skin here, ensuring the uniformity of the electrical stimulation during electrical stimulation, and improving the quality of rehabilitation; in the initial state, the suspension bowl is placed in the floating cavity under the action of the buoyancy of the water body, and the conductive liquid in the inner cavity of the suspension bowl is in a horizontal state. The current on the regulating circuit composed of the two conductive sheets and the power supply is in a stable state. When the muscle begins to During contraction, the muscle fibers begin to thicken, and the support frame is driven to tilt through the stimulation electrode and the adjustment cylinder. The floating cavity wall and the bracket are in frictional contact, and the suspension bowl is driven to tilt under the action of static friction, so that the volume of the conductive liquid between the two conductive plates is reduced, that is, the number of ions involved in conduction is reduced. Under the rated voltage of the power supply, the current of the adjustment circuit decreases. The greater the degree of muscle contraction, that is, the greater the degree of tilt of the suspension bowl, the smaller the current value of the adjustment circuit; if the stimulation intensity is large, the degree of muscle contraction increases, thereby increasing the current value of the adjustment circuit. According to the detected current value, the input current of the micro-cylinder is controlled, and the micro-cylinder drives the conductive ring to move toward the side close to the micro-cylinder. The conductive ring and the auxiliary heating resistor are connected in series to the stimulation circuit. When the conductive ring slides toward the micro-cylinder, the resistance value of the auxiliary heating resistor connected to the stimulation circuit increases. When the output voltage of the control host is stable, the current of the stimulation circuit is instantaneously weakened, thereby reducing the stimulation of the stimulation electrode to the human body, avoiding excessive stimulation, and improving the electrical stimulation rehabilitation effect.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0035] Example: Figures 1-8 As shown, the present invention provides a technical solution for a thermo-thermal low-frequency therapeutic device with an automatic adjustment electrical stimulation function.
[0036] A thermothermal low-frequency therapeutic device with an automatically adjustable electrical stimulation function comprises a carrier 1, a skin cleansing device 2, an adjusting device 3 and a control host 4. The control host 4 is electrically connected to the adjusting device 3, the skin cleansing device 2 is connected to the carrier 1, the skin cleansing device 2 is connected to the adjusting device 3, and the adjusting device 3 is connected to the carrier 1. The control host 4 is used to control the output of the stimulation current.
[0037] The control host 4 is used to provide low-frequency pulse current and provides multiple interfaces. When performing electrical stimulation treatment, the support frame 1 serves as the main supporting base and is placed on the part of the human body to be stimulated. The skin cleansing device 2 is used to locally clean the part to be treated, and warm airflow is provided for local heating. After cleaning is completed, local electrical stimulation is performed through the adjustment device 3.
[0038] Furthermore, the skin cleansing device 2 includes a drive motor 21, a skin cleansing roller 22 and a gear 23. A drive cavity 11 is provided on both sides of the bottom surface of the carrier 1. The drive motor 21 is placed in the drive cavity 11. A gear 23 is provided at the output end of the drive motor 21. A tooth groove 12 is provided along the wall of the drive cavity 11. The tooth surface of the gear 23 and the tooth groove 12 are engaged, and the drive motor 21 and the drive cavity 11 are slidably connected;
[0039] The adjustment device 3 includes a stimulation electrode 31 and an adjustment cylinder 32. The adjustment cylinder 32 is tightly connected to the housing of the drive motor 21. The output end of the adjustment cylinder 32 is tightly connected to the stimulation electrode 31. The control host 4 is used to power the stimulation electrode 31. The control host 4 and the stimulation electrode 31 form a stimulation circuit.
[0040] The driving motor 21 is placed in the driving cavity 11 as the main power source. When the driving motor 21 outputs torque, it can move laterally along the driving cavity 11 through the engagement of the gear 23 and the tooth groove 12. The skin cleaning roller 22 is made of flexible material and is used to perform local cleaning of the part to be electrically stimulated to prevent hair, sweat, etc. from affecting the effect of electrical stimulation. For example, when the waist is locally cleaned, the two driving motors 21 rotate in opposite directions to perform synchronous cleaning and improve cleaning efficiency. After cleaning is completed, the adjusting cylinder 32 is fixed to the housing of the driving motor 21 and can move with the driving motor 21. The adjusting cylinder 32 is moved to the part to be electrically stimulated by the driving motor 21, and the adjusting cylinder 32 is controlled to output displacement downward, driving the stimulating electrode 31 downward until it fits the part to be electrically stimulated. The host 4 is controlled to output a pulse motor so that the stimulating electrode 31 stimulates the muscle, causing the muscle to produce a tremor-like contraction, thereby performing rehabilitation training and promoting functional recovery.
[0041] Furthermore, the skin cleansing device 2 also includes a temperature control component 24, a power supply and a hot air pipe 25. The temperature control component 24 includes an electrode sheet 241. Electrode sheets 241 are respectively provided on both sides of the skin cleansing roller 22 along the circumference. The electrode sheets 241 are ring-shaped. Two adjacent electrode sheets 241 and two terminal blocks of the power supply are electrically connected to form a detection circuit. The skin cleansing roller 22 is provided with a plurality of air outlets along the circumference, and the hot air pipe 25 is connected to the air outlet pipe.
[0042] When the skin cleaning roller 22 cleans the area to be electrically stimulated, air is ejected through the hot air pipe 25 to assist in cleaning the area to be electrically stimulated and improve the cleaning effect. The hot air pipe 25 is connected to the hot and humid air flow, which can locally keep the area to be electrically stimulated warm. At the same time, after the cleaning is completed, the humidity of the skin surface is guaranteed to be within a certain range. The circuit electrically connected to the two electrode pieces 241 and the terminal of the power supply is conducted through the wet air flow, so as to detect the local humidity of the area to be electrically stimulated. The detection circuit is electrically connected to the drive motor 21, and the speed of the drive motor 21 is adjusted according to the measured current value. When the local humidity is low, the speed of the drive motor 21 is reduced to increase the density of the hot and humid air flow here, thereby improving the electrical conductivity of the skin here, ensuring the uniformity of the electrical stimulation during electrical stimulation, and improving the quality of rehabilitation.
[0043] Furthermore, a floating chamber 13 is provided on the carrier 1, and the floating chamber 13 carries water. The inlet of the hot air pipe 25 is connected to the pipeline of the floating chamber 13. The temperature control component 24 also includes an electric heating block 242. The electric heating block 242 is placed in the water body of the floating chamber 13, and the control host 4 supplies power to the electric heating block 242.
[0044] The first port of the control host 4 is used to power the stimulation electrode 31, and the second port is used to power the electric heating block 242. The water in the floating cavity 13 is heated by the electric heating block 242. A pump body is set at the connection between the hot air pipe 25 and the floating cavity 13 to supply humid hot air flow to make the humid hot air flow supply rate uniform.
[0045] Furthermore, the adjustment device 3 also includes an induction component 33, which is placed in the floating cavity 13. The induction component 33 includes a suspension bowl 331 and a conductive sheet 332. A plurality of brackets 333 are provided on the outer ring of the suspension bowl 331. The brackets 333 are in frictional contact with the wall of the floating cavity 13 away from the side of the suspension bowl 331. A cover is provided on the upper side of the suspension bowl 331. The suspension bowl 331 contains conductive liquid. Two conductive sheets 332 are provided. The lower ends of the two conductive sheets 332 are inserted into the conductive liquid, and the upper ends of the two conductive sheets 332 are electrically connected to the power supply to form an adjustment circuit.
[0046] The sensor assembly 33 is provided to detect the degree of muscle contraction. Initially, the levitation bowl 331 rests within the floating chamber 13 under the influence of the water's buoyancy. The conductive fluid within the levitation bowl 331 is horizontal, and the current in the regulation circuit formed by the two conductive plates 332 and the power supply is stable. When the muscle begins to contract, the muscle fibers begin to thicken. The stimulation electrodes 31 and the regulation cylinder 32 cause the support frame 1 to tilt, and frictional contact between the walls of the floating chamber 13 and the support 333 occurs. Static friction drives the levitation bowl 331 to tilt, reducing the volume of the conductive fluid between the two conductive plates 332. This reduces the number of ions involved in conduction, and at the rated voltage of the power supply, the current in the regulation circuit decreases. The greater the degree of muscle contraction, the greater the tilt of the levitation bowl 331, and the smaller the current in the regulation circuit. As the levitation bowl 331 tilts, its center rises. Under the influence of gravity, it overcomes the friction between the support 333 and the walls of the floating chamber 13, returning to its lowest point until the cover and the upper surface of the conductive fluid are horizontal again, facilitating continuity testing.
[0047] Furthermore, the adjustment device 3 also includes an auxiliary heating component 34, which includes an auxiliary heating resistor 341, a micro-cylinder 342 and a conductive ring 343. The lower end of the floating cavity 13 is provided with an adjustment groove 14, the upper end of the auxiliary heating resistor 341 is inserted into the floating cavity 13, the lower end of the auxiliary heating resistor 341 is placed in the adjustment groove 14, the micro-cylinder 342 is placed in the adjustment groove 14, the output end of the micro-cylinder 342 is tightly connected to the conductive ring 343, the conductive ring 343 and the auxiliary heating resistor 341 are in sliding contact, and the end of the auxiliary heating resistor 341 away from the micro-cylinder 342 and the side of the conductive ring 343 are connected in series to the stimulation circuit;
[0048] When lowering: the micro-cylinder 342 drives the conductive ring 343 to move toward the side close to the micro-cylinder 342, and the resistance value of the auxiliary heating resistor 341 connected to the stimulation circuit increases.
[0049] By setting up an auxiliary heating component 34, a moist and hot air flow is assisted in being generated. When performing electrical stimulation adjustment, if the stimulation intensity is large, the degree of muscle contraction increases, thereby increasing the current value of the adjustment circuit. According to the detected current value, the input current of the micro-cylinder 342 is controlled, and the micro-cylinder 342 drives the conductive ring 343 to move toward the side close to the micro-cylinder 342. The conductive ring 343 and the auxiliary heating resistor 341 are connected in series to the stimulation circuit. When the conductive ring 343 slides toward the micro-cylinder 342, the resistance value of the auxiliary heating resistor 341 connected to the stimulation circuit increases. When the output voltage of the control host 4 is stable, the current of the stimulation circuit is instantaneously weakened, thereby reducing the stimulation of the stimulation electrode 31 to the human body, avoiding excessive stimulation, and improving the electrical stimulation rehabilitation effect.
[0050] As an optimization, the micro-cylinder 342 is electrically connected to a regulating circuit. Based on the current detected by the regulating circuit, the degree of muscle contraction under electrical stimulation is detected, thereby controlling the start and stop of the micro-cylinder 342, adjusting the current of the stimulation circuit, and automatically adjusting the intensity of electrical stimulation.
[0051] As an optimization, the floating cavity 13 is spherical. The spherical setting of the floating cavity 13 improves the stability of the detection.
[0052] As an optimization, the outer side of the bracket 333 is set in an arc shape, and the arc shape of the outer side of the bracket 333 is adapted to the floating cavity 13. The outer arc shape of the bracket 333 allows the bracket 333 to make surface contact with the wall surface of the floating cavity 13, thereby improving transmission efficiency and facilitating muscle tension detection.
[0053] The working principle of the present invention is as follows: the hot air pipe 25 is used to spray air to assist in cleaning the area to be electrically stimulated and improve the cleaning effect. The hot air pipe 25 is connected to the moist hot air flow, which can locally keep the area to be electrically stimulated warm. At the same time, after the cleaning is completed, the humidity of the skin surface is guaranteed to be within a certain range. The circuit electrically connected to the two electrode sheets 241 and the terminal of the power supply is conducted through the moist air flow, thereby detecting the local humidity of the area to be electrically stimulated. The detection circuit is electrically connected to the drive motor 21. According to the measured current value, the speed of the drive motor 21 is adjusted. When the local humidity is low, the speed of the drive motor 21 is reduced to increase the density of the moist hot air flow here, thereby increasing the electrical conductivity of the skin here, ensuring the uniformity of the electrical stimulation during electrical stimulation and improving the quality of rehabilitation. In the initial state, the suspension bowl 331 is placed in the floating chamber 13 under the action of the buoyancy of the water body. The conductive liquid in the inner cavity of the suspension bowl 331 is in a horizontal state. The current on the regulating circuit composed of the two conductive sheets 332 and the power supply is in a stable state. When the muscle begins to contract, the muscle fibers begin to thicken. By stimulating The electrodes 31 and adjustment cylinder 32 drive the support frame 1 to tilt, causing frictional contact between the wall of the floating chamber 13 and the bracket 333. Static friction drives the floating bowl 331 to tilt, reducing the volume of the conductive liquid between the two conductive plates 332. This reduces the number of ions involved in conduction. At the rated voltage of the power supply, the current in the regulation circuit decreases. The greater the degree of muscle contraction, that is, the greater the tilt of the floating bowl 331, the smaller the current in the regulation circuit. If the stimulation intensity is high, the degree of muscle contraction increases, thereby increasing the current in the regulation circuit. Based on the detected current value, the input current of the micro-cylinder 342 is controlled, and the micro-cylinder 342 drives the conductive ring 343 to move closer to the micro-cylinder 342. The conductive ring 343 and the auxiliary thermal resistor 341 are connected in series to the stimulation circuit. As the conductive ring 343 slides toward the micro-cylinder 342, the resistance of the auxiliary thermal resistor 341 connected to the stimulation circuit increases. When the output voltage of the control host 4 stabilizes, the current in the stimulation circuit decreases instantaneously, thereby reducing stimulation to the human body by the stimulation electrode 31, avoiding excessive stimulation and improving the electrical stimulation rehabilitation effect.
