Description

Technical Field

[0001] The invention relates to the technical field of therapeutic instruments, in particular to a warm low-frequency therapeutic instrument with an automatic regulating electrical 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, mainly relying on the operator's accumulated experience. For example, before conducting electrical stimulation therapy, the skin surface needs to be cleaned locally to remove surface stains such as grease and sweat to prevent affecting the adhesion performance of the electrical stimulation electrode and to avoid corrosion to the electrical stimulation electrode body. The main cleaning method is currently local wiping, which can easily cause local water residue, affect local conductivity, and thus reduce the conduction accuracy of electrical stimulation.

[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 will easily lead to the inability to meet the intensity of rehabilitation training and prolong the rehabilitation time. Summary of the invention

[0005] The purpose 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 warm low-frequency therapeutic device with an automatic adjustable electrical stimulation function comprises a support 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 support frame, the skin cleaning device is connected to the adjusting device, the adjusting device is connected to the support frame, and the control host is used to control the stimulation current output.

[0008] The control host is used to provide low-frequency pulse current and provides multiple interfaces. When conducting electrical stimulation therapy, the support frame serves as the main supporting basis and is placed on the part of the human body to be stimulated. The skin cleansing device 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.

[0009] Furthermore, the skin cleaning device includes a driving motor, a skin cleaning roller and a gear. A driving cavity is respectively provided on both sides of the bottom surface of the carrier frame. The driving motor is placed in the driving cavity. A gear is provided at the output end of the driving motor. A tooth groove is provided along the wall surface of the driving cavity. The gear and the tooth groove are meshed. The driving motor and the driving cavity are slidably connected.

[0010] The regulating device comprises a stimulation electrode and an regulating cylinder, the regulating cylinder is firmly connected to the driving motor housing, the output end of the regulating cylinder is firmly connected to the stimulation electrode, the control host is used to supply power to the stimulation electrode, and 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 to improve cleaning efficiency. After the 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, drives the stimulation electrode downward, until it fits to the area to be electrically stimulated, controls the host to output a pulse motor, causes the stimulation electrode to stimulate the muscle, and causes 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 respectively provided on both sides of the skin cleansing roller along the circumference. The electrode sheets are ring-shaped. Two adjacent electrode sheets and two connecting terminals of the power supply are electrically connected to form a detection circuit. The skin cleansing roller is provided with a plurality of air outlets along the circumference, and the hot air pipe is connected to the air outlet pipe.

[0013] When the skin cleaning roller cleans the area to be electrically stimulated, jets are sprayed through the hot air pipe to assist in cleaning the area to be electrically stimulated and improve the cleaning effect. The hot air pipe 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 wiring terminals of the two electrode sheets and the power supply is conducted through the humid 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, 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 hot and humid 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, the floating cavity carries water, the hot air pipe inlet is connected to the floating cavity pipeline, the temperature control component also includes an electric heating block, the electric heating block is placed in the water body of the floating cavity, and 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. The water in the floating cavity is heated by the electric heating block. A pump body is set at the connection between the hot air pipe and the floating cavity to supply humid hot air flow to make the humid hot air flow supply rate uniform.

[0016] Furthermore, the regulating 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 plurality of brackets are provided on the outer ring of the suspension bowl. The brackets are in frictional contact with the wall of the floating cavity away from the side of the suspension bowl. A sealing cover is provided on the upper side of the suspension bowl. The suspension bowl contains a 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 a power source to form an regulating circuit.

[0017] The degree of muscle contraction is detected by setting a sensing component. In the initial state, the suspension bowl is stationary in the floating cavity under the buoyancy of the water body. The conductive liquid in the inner cavity of the suspension bowl is in a horizontal state. The current on the regulating circuit composed of two conductive sheets and the power supply is in a stable state. When the muscle begins to contract, the muscle fibers begin to thicken. The stimulating electrode and the regulating cylinder drive the support frame to tilt. The wall of the floating cavity and the support are in friction contact. Under the action of static friction, the suspension bowl is driven to tilt, so that the volume of the conductive liquid between the two conductive sheets is reduced, that is, the number of ions involved in the conduction is reduced. Under the rated voltage of the power supply, the current of the regulating circuit is reduced. The greater the degree of muscle contraction, that is, the greater the degree of inclination of the suspension bowl, the smaller the current value of the regulating circuit. When the suspension bowl tilts, due to the rise of the center, it will overcome the friction between the support and the wall of the floating cavity under the action of gravity and return to the lowest point until the cover and the upper surface of the conductive liquid are in a horizontal state again, so as to facilitate continuity detection.

[0018] Furthermore, the regulating 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 adjusting 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 adjusting groove, the micro-cylinder is placed in the adjusting 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-motion cylinder drives the conductive ring to move toward the side close to the micro-motion 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 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 rehabilitation effect of electrical stimulation.

[0021] As an optimization, the micro-cylinder is electrically connected to the regulating circuit. According to the current detected by the regulating circuit, the contraction degree of the muscle under electrical stimulation is detected, thereby controlling the start and stop of the micro-cylinder, adjusting the current of the stimulation circuit, and automatically adjusting the intensity of electrical stimulation.

[0022] As an optimization, the floating cavity is spherical. The spherical setting of the floating cavity improves the stability of the detection.

[0023] As an optimization, the outer arc of the bracket is set, and the arc of the outer arc of the bracket is adapted to the floating cavity. By setting the outer arc of the bracket, the bracket and the wall of the floating cavity are in surface contact, which improves the transmission efficiency and facilitates 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 a humid 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 wiring terminals of the two electrode sheets and the power supply is conducted through the humid 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 humid hot air flow here is increased, thereby increasing the 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 buoyancy of the water body, the conductive liquid in the inner cavity of the suspension bowl is in a horizontal state, and 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, muscle fibers begin to thicken, and the support frame is tilted through the stimulation electrode and the adjustment cylinder. The wall of the floating cavity and the support are in frictional contact, and the suspension bowl is tilted under the action of static friction, so that the volume of the conductive liquid between the two conductive sheets 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 inclination 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 thermal resistor are connected in series to the stimulation circuit. When the conductive ring slides toward the micro-cylinder, the resistance value of the auxiliary thermal resistor connected to the stimulation circuit increases. When the output voltage of the control host is stable, the current of the stimulation circuit is instantly weakened, thereby reducing the stimulation of the stimulation electrode to the human body, avoiding excessive stimulation, and improving the rehabilitation effect of electrical stimulation.

[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 is used as the main supporting basis 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.

[0038] Furthermore, the skin cleaning device 2 includes a driving motor 21, a skin cleaning roller 22 and a gear 23. A driving cavity 11 is provided on both sides of the bottom surface of the carrier frame 1. The driving motor 21 is placed in the driving cavity 11. A gear 23 is provided at the output end of the driving motor 21. A tooth groove 12 is provided along the wall surface of the driving cavity 11. The gear 23 is meshed with the tooth surface of the tooth groove 12. The driving motor 21 is slidably connected with the driving cavity 11.

[0039] The adjusting device 3 includes a stimulation electrode 31 and an adjusting cylinder 32. The adjusting cylinder 32 is firmly connected to the housing of the driving motor 21. The output end of the adjusting cylinder 32 is firmly connected to the stimulation electrode 31. The control host 4 is used to supply power to 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, the gear 23 and the tooth groove 12 are meshed, and the driving cavity 11 can be moved laterally. The skin cleaning roller 22 is made of flexible material and is used to locally clean 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 to improve the cleaning efficiency. After the cleaning is completed, the adjusting cylinder 32 is fixed on 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 is attached to the part to be electrically stimulated, and controlling the host 4 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 circumferential direction. The electrode sheets 241 are ring-shaped. Two adjacent electrode sheets 241 and two wiring terminals 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 circumferential direction, 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, jets are sprayed 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 sheets 241 and the terminal of the power supply is conducted by the humid 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 supporting frame 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, and the electric heating block 242 is placed in the water body of the floating chamber 13. 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 regulating device 3 also includes a sensing component 33, which is placed in the floating chamber 13. The sensing 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 chamber 13 away from the side of the suspension bowl 331. A sealing cover is provided on the upper side of the suspension bowl 331. The suspension bowl 331 contains a conductive liquid. Two conductive sheets 332 are provided. The lower ends of the two conductive sheets 332 are inserted into the conductive liquid. The upper ends of the two conductive sheets 332 are electrically connected to the power supply to form a regulating circuit.

[0046] The degree of muscle contraction is detected by setting the induction component 33. In the initial state, the suspension bowl 331 is stationary in the floating chamber 13 under the buoyancy of the water body. The conductive liquid in the inner chamber 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. The stimulating electrode 31 and the regulating cylinder 32 drive the support frame 1 to tilt. The wall surface of the floating chamber 13 and the support 333 are in friction contact. Under the action of static friction, the suspension bowl 331 is driven to tilt, so that the volume of the conductive liquid between the two conductive sheets 332 is reduced, that is, the number of ions involved in the conduction is reduced. Under the rated voltage of the power supply, the current of the regulating circuit is reduced. The greater the degree of muscle contraction, that is, the greater the degree of inclination of the suspension bowl 331, the smaller the current value of the regulating circuit. When the suspension bowl 331 tilts, due to the rise of the center, it will overcome the friction between the support 333 and the wall surface of the floating chamber 13 under the action of gravity and return to the lowest point until the cover and the upper surface of the conductive liquid are in a horizontal state again, so as to facilitate continuity detection.

[0047] Furthermore, the regulating 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.

[0048] When lowering: the micro-motion cylinder 342 drives the conductive ring 343 to move toward the side close to the micro-motion cylinder 342, and the resistance value of the auxiliary thermal 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 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 instantly 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 the regulating circuit. According to the current detected by the regulating circuit, the contraction degree of the muscle 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 electrical stimulation intensity.

[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 arc of the bracket 333 is set, and the arc of the outer side of the bracket 333 is adapted to the floating cavity 13. The outer arc of the bracket 333 is set so that the bracket 333 and the wall of the floating cavity 13 are in surface contact, which improves the transmission efficiency and facilitates 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 part to be electrically stimulated, thereby improving the cleaning effect. The hot air pipe 25 is connected to the moist hot air flow, which can locally keep the part 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 wiring terminals of the two electrode sheets 241 and the power supply is conducted through the moist air flow, thereby detecting the local humidity of the part 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 current value measured. 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 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 cavity 13 under the buoyancy of the water body, and 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 fiber begins to thicken. By stimulating The electrode 31 and the adjustment cylinder 32 drive the support frame 1 to tilt, and the wall of the floating cavity 13 and the bracket 333 are in frictional contact. Under the action of static friction, the suspension bowl 331 is driven to tilt, so that the volume of the conductive liquid between the two conductive sheets 332 is reduced, that is, the number of ions involved in the conduction is reduced. Under the rated voltage of the power supply, the current of the adjustment circuit is reduced. The greater the degree of muscle contraction, that is, the greater the degree of inclination of the suspension bowl 331, 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 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 thermal 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 thermal 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 instantly weakened, thereby reducing the stimulation of the stimulation electrode 31 to the human body, avoiding excessive stimulation, and improving the electrical stimulation rehabilitation effect.
