Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a non-invasive capacitive field shortwave therapy machine. Background Technology

[0002] Capacitive field shortwave thermotherapy is widely used in the physical therapy and rehabilitation of diseases such as orthopedic inflammation, soft tissue injury, and chronic pelvic inflammation due to its advantages of being non-invasive, deep heat penetration, and easy to operate. Its working principle is as follows: a high-frequency alternating capacitive electric field is formed between the upper and lower opposing capacitive electrodes. The electric field energy penetrates human tissue and causes the ions and polar molecules inside the lesion to oscillate and rub at high speed to generate endogenous heat, thus achieving deep thermal therapy.

[0003] However, due to the low conductivity and high impedance of human adipose tissue, under the action of a high-frequency capacitive electric field, the electric field energy is easily deposited in the fat layer, forming a heat accumulation. The heat cannot be dissipated in time, which can cause mild burning pain and soreness in the patient's skin, or even subcutaneous fat burns and hardening in severe cases. At the same time, the continuous accumulation of heat in the fat layer will form a heat insulation barrier, weakening the penetration efficiency of the electric field to deep lesions and affecting the treatment effect. Summary of the Invention

[0004] Therefore, it is necessary to provide a non-invasive capacitive field shortwave therapy machine to address the technical problem that current capacitive field shortwave thermotherapy easily causes heat accumulation in human fat tissue, thus affecting the treatment effect.

[0005] The above objectives are achieved through the following technical solutions: A non-invasive capacitive field shortwave therapy machine includes a treatment bed and a capacitor plate assembly. The treatment bed is equipped with a lifting box that can slide vertically. The length of the treatment bed extends in the front-to-back direction, and the width of the treatment bed extends horizontally. The capacitor plate assembly includes a horizontally arranged upper electrode plate and a lower electrode plate. The upper electrode plate is oscillating horizontally within the lifting box, and the lower electrode plate is oscillating horizontally within the treatment bed. The upper and lower electrode plates can oscillate synchronously in opposite directions so that the capacitive field formed between the upper and lower electrode plates can always surround the treatment area on the human body surface.

[0006] Furthermore, the lifting box has an upper arc-shaped groove inside, and the treatment bed has a lower arc-shaped groove inside. The axes of the upper arc-shaped groove and the lower arc-shaped groove are parallel and both extend in the front-back direction. An upper swing arm is slidably disposed in the upper arc-shaped groove, and a lower swing arm is slidably disposed in the lower arc-shaped groove. The upper electrode plate is disposed at the lower end of the upper swing arm, and the lower electrode plate is disposed at the upper end of the lower swing arm.

[0007] Furthermore, both the lifting box and the treatment bed are equipped with two mounting plates spaced apart along the front-to-back direction. The upper arc-shaped groove has two mounting plates located within the lifting box, and the lower arc-shaped groove has two mounting plates located within the treatment bed. Both the upper and lower swing arms have T-shaped blocks with two insertion ends distributed front-to-back. The two insertion ends of the upper swing arm are inserted into the two upper arc-shaped grooves, and the two insertion ends of the lower swing arm are inserted into the two lower arc-shaped grooves. Each insertion end has an arc-shaped rack. Each mounting plate has a drive motor, and the output end of the drive motor is connected to a gear. Each gear meshes with the arc-shaped rack on the corresponding insertion end. The drive motors corresponding to the upper and lower swing arms are configured to rotate synchronously in opposite directions to achieve synchronous reverse swinging of the upper and lower swing arms.

[0008] Furthermore, each T-shaped block is equipped with a linear drive cylinder that can extend and retract in the vertical direction, and the end of the linear drive cylinder is connected to a clamping plate; a frame is detachably installed on the clamping plate, and the upper electrode plate or the lower electrode plate is fixed inside the frame and assembled onto the clamping plate through the frame.

[0009] Furthermore, a pad is also installed inside the frame, and the pad is located on the side of the upper or lower electrode plate facing the human body surface.

[0010] Furthermore, the non-invasive capacitive field shortwave therapy machine also includes a cooling patch and a control system. The cooling patch is placed between the upper electrode plate and the human body surface. Multiple cooling pipes are embedded inside the cooling patch, evenly distributed in the left-right direction, and each cooling pipe extends in the front-back direction. The treatment bed is equipped with a main unit, and the control system is integrated into the main unit. The control system can selectively introduce coolant into the cooling pipes of a designated area according to the real-time swing position of the upper electrode plate, thereby cooling and reducing the temperature of the designated area. The designated area corresponds to the treatment area on the human body surface that has been covered by the upper electrode plate.

[0011] Furthermore, both ends of the cooling patch are provided with cylinders, the axis of which extends in the left-right direction. The inside of the cylinder is sealed, sliding, and anti-rotationally fitted with a piston rod. The end of the piston rod is provided with a liquid inlet, which is used to introduce coolant into the piston rod or to allow coolant inside the piston rod to flow out. The side wall of the piston rod is also provided with a connecting port. The control system can adjust the position of the piston rod in the cylinder according to the real-time swing position of the upper electrode plate so that the connecting port is connected to the cooling pipe of the designated area, thereby cooling the designated area.

[0012] Furthermore, a partition is provided in the middle of the cylinder, which divides the interior of the cylinder into a first semicircular cavity and a second semicircular cavity distributed front to back. The first semicircular cavity is positioned away from the cooling pipe relative to the second semicircular cavity. A piston part is provided at the end of the piston rod, and a sealing plate is also provided on the piston rod. Both the sealing plate and the piston part can slide axially along the inner wall of the cylinder. An adjustment cavity is formed on the side of the sealing plate away from the piston part and corresponding to the space of the first semicircular cavity. The adjustment cavity is used to adjust the relative position of the piston rod in the cylinder. The communication port is located between the piston part and the sealing plate. The space between the piston part and the sealing plate and corresponding to the second semicircular cavity is a communication cavity. The communication port is connected to the cooling pipe of a designated area through the communication cavity.

[0013] Furthermore, the cylinder is provided with an adjustment port, which is connected to the adjustment cavity. The control system can inject or draw coolant into the adjustment cavity through the adjustment port according to the real-time swing position of the upper electrode plate, so as to change the relative position of the piston rod in the cylinder.

[0014] Furthermore, both the piston portion and the sealing plate are provided with clearance grooves extending in the left-right direction, and the clearance grooves are in a sealing sliding fit with the partition plate.

[0015] The beneficial effects of this invention are: The non-invasive capacitive field shortwave therapy machine provided by the present invention, firstly, by making the upper electrode plate and the lower electrode plate swing synchronously in opposite directions, the capacitive field formed between the upper electrode plate and the lower electrode plate can always surround the treatment area on the surface of the human body, realizing multi-directional treatment and ensuring the treatment effect of the treatment area. At the same time, because the position of the capacitive field changes continuously, the heating position of the fat layer near the treatment area can change continuously, avoiding the same position being heated for a long time, which may cause burns or affect the treatment effect.

[0016] Second, the control system tracks the swing position of the upper electrode plate in real time and cools the treated area in a timely manner to improve cooling efficiency. Attached Figure Description

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1 to 12 As shown, an embodiment of the present invention provides a non-invasive capacitive field shortwave therapy machine, including a treatment bed 110 and a capacitor plate assembly; the treatment bed 110 is provided with a lifting box 120 that can slide in the vertical direction, the length of the treatment bed 110 extends in the front-back direction, and the width of the treatment bed 110 extends in the left-right direction; the capacitor plate assembly includes a horizontally arranged upper electrode plate 202 and a lower electrode plate, the upper electrode plate 202 is oscillating and installed in the lifting box 120 in the left-right direction, and the lower electrode plate is oscillating and installed in the treatment bed 110 in the left-right direction. The upper electrode plate 202 and the lower electrode plate can oscillate synchronously in opposite directions so that the capacitive field formed between the upper electrode plate 202 and the lower electrode plate can always surround the treatment area 401 on the surface of the human body 400.

[0023] Specifically, a hydraulic telescopic cylinder 130 is provided on one side of the treatment bed 110. The telescopic end of the hydraulic telescopic cylinder 130 is connected to the lifting box 120 and is used to drive the lifting box 120 to move up and down.

[0024] like Figure 3 As shown, the upper electrode plate 202 and the lower electrode plate are in their initial positions at this time. The circles formed by the dashed lines in the figure represent the motion trajectories of the upper electrode plate 202 and the lower electrode plate. Figure 4As shown, the upper electrode plate 202 swings to the right along the motion trajectory (corresponding to the direction indicated by the arrow in the figure), and the lower electrode plate swings to the left along the circular trajectory, so that the capacitive field formed between the upper electrode plate 202 and the lower electrode plate is always aligned with the treatment area 401 (i.e., the treatment point).

[0025] The non-invasive capacitive field shortwave therapy machine of the present invention enables the upper electrode plate 202 and the lower electrode plate to swing synchronously in opposite directions, so that the capacitive field formed between the upper electrode plate 202 and the lower electrode plate can always surround the treatment area 401 on the surface of the human body 400, realizing multi-directional treatment and ensuring the treatment effect of the treatment area 401. At the same time, due to the continuous change of the position of the capacitive field, the heating position of the fat layer near the treatment area 401 can be continuously changed, avoiding the same position being heated for a long time, which may cause burns or affect the treatment effect.

[0026] Furthermore, the lifting box 120 has an upper arc-shaped groove 201 inside, and the treatment bed 110 has a lower arc-shaped groove inside. The upper arc-shaped groove 201 and the lower arc-shaped groove are parallel to each other and both extend in the front-back direction. An upper swing arm 200 is slidably disposed in the upper arc-shaped groove 201, and a lower swing arm 500 is slidably disposed in the lower arc-shaped groove. The upper electrode plate 202 is disposed at the lower end of the upper swing arm 200, and the lower electrode plate is disposed at the upper end of the lower swing arm 500.

[0027] Specifically, both the upper swing arm 200 and the lower swing arm 500 extend in the vertical direction. The upper arc groove 201 provides a definite motion trajectory for the upper swing arm 200, and the lower arc groove provides a definite motion trajectory for the lower swing arm 500. The structure is simple and facilitates the synchronous reverse swinging of the upper swing arm 200 and the lower swing arm 500.

[0028] Furthermore, both the lifting box 120 and the treatment bed 110 are provided with two mounting plates 203 spaced apart in the front-to-back direction. Two upper arc-shaped grooves 201 are provided and located on the two mounting plates 203 inside the lifting box 120, and two lower arc-shaped grooves are provided and located on the two mounting plates 203 inside the treatment bed 110. Both the upper swing arm 200 and the lower swing arm 500 have T-shaped blocks 206, each with two insertion ends distributed front-to-back. The two insertion ends of the upper swing arm 200 are respectively inserted into the two upper arc-shaped grooves. Within 201, the two insertion ends of the lower swing arm 500 are respectively inserted into two lower arc-shaped grooves. Each insertion end is provided with an arc-shaped rack 2061. Each mounting plate 203 is provided with a drive motor 204. The output end of the drive motor 204 is connected to a gear 205. Each gear 205 meshes with the arc-shaped rack 2061 on the corresponding insertion end. The drive motor 204 corresponding to the upper swing arm 200 and the drive motor 204 corresponding to the lower swing arm 500 are configured to rotate synchronously in opposite directions to achieve synchronous reverse swinging of the upper swing arm 200 and the lower swing arm 500. In this way, the front and rear ends of the T-shaped block 206 are supported simultaneously, making the swinging of the upper swing arm 200 or the lower swing arm 500 more stable. Moreover, the swinging angle of the upper electrode plate 202 or the lower electrode plate can be directly controlled by the angle control of the drive motor 204.

[0029] Furthermore, each T-shaped block is internally equipped with a linear drive cylinder 207 capable of extending and retracting in the vertical direction. The end of each linear drive cylinder 207 is connected to a clamping plate 208. A frame 210 is detachably mounted on the clamping plate 208. The upper electrode plate 202 or lower electrode plate is fixed within the frame 210 and assembled onto the clamping plate 208 via the frame 210. The linear drive cylinder 207 is connected to a cylinder plate 2071. The clamping plate 208 and cylinder plate 2071 are detachably connected by bolts, and the frame 210 is detachably connected to the clamping plate 208 by bolts. The linear drive cylinder 207 can control the distance between the upper electrode plate 202 or lower electrode plate and the surface of the human body 400, thereby adapting to different body shapes or body parts.

[0030] Furthermore, a pad 209 is also installed within the frame 210, located on the side of the upper electrode plate 202 or lower electrode plate facing the human body 400. The pad 209 serves as a physical insulating layer, preventing the upper electrode plate 202 or lower electrode plate from directly contacting the skin and causing stinging or burns. The pad 209 can be made of a flexible material (such as silicone or sponge) to provide cushioning when in contact with the human body 400.

[0031] Furthermore, the non-invasive capacitive field shortwave therapy machine also includes a cooling patch 300 and a control system. The cooling patch 300 is disposed between the upper electrode plate 202 and the body surface of the human body 400. Multiple cooling pipes 302, evenly distributed along the left-right direction, are embedded inside the cooling patch 300, and each cooling pipe 302 extends along the front-back direction. A main unit 150 is mounted on the treatment bed 110, and the control system is integrated within the main unit 150. The control system can selectively introduce coolant into the cooling pipes 302 of a designated area based on the real-time swing position of the upper electrode plate 202, thereby cooling and reducing the temperature of that designated area. The designated area corresponds to the treatment area 401 on the body surface of the human body 400 that has been covered by the upper electrode plate 202. The cooling patch 300 is made of non-conductive material, and the cooling pipes 302 are insulating tubes, which do not interfere with the distribution of the capacitive field.

[0032] This control system tracks the swing position of the upper electrode plate 202 in real time, promptly cooling the treated area and improving cooling efficiency. Specifically, each drive motor 204 has a rotary encoder at its output end, which is connected to the control system. The control system calculates the real-time swing position of the upper electrode plate 202 based on the real-time rotation angle of the drive motor 204 fed back by the rotary encoder, combined with the transmission ratio of the gear 205 and the arc rack 2061.

[0033] Furthermore, the cooling patch 300 has cylinders 301 at both its front and rear ends. The axis of each cylinder 301 extends in the left-right direction. A piston rod 303 is fitted inside the cylinder 301 with a sealed, sliding, and anti-rotation assembly. A liquid inlet 3012 is provided at the end of the piston rod 303 for introducing coolant into the piston rod 303 or for allowing coolant to flow out of the piston rod 303. A connecting port 3031 is also provided on the side wall of the piston rod 303. The control system can adjust the position of the piston rod 303 within the cylinder 301 according to the real-time swing position of the upper electrode plate 202, so that the connecting port 3031 connects to the cooling pipe 302 in the designated area, thereby cooling that designated area. This method of introducing coolant into the cooling pipe 302 in the designated area by adjusting the position of the piston rod 303 is simple in structure, requires no solenoid valve for control, and is not affected by capacitive field interference.

[0034] Furthermore, a partition 305 is provided in the middle of the cylinder 301, which divides the interior of the cylinder 301 into a first semicircular cavity and a second semicircular cavity distributed front to back. The first semicircular cavity is positioned away from the cooling pipe 302 relative to the second semicircular cavity. A piston part 3033 is provided at the end of the piston rod 303, and a sealing plate 3034 is also provided on the piston rod 303. Both the sealing plate 3034 and the piston part 3033 can slide axially along the inner wall of the cylinder 301. An adjustment cavity 304 is formed on the side of the piston section 3033 away from the first semicircular cavity. The adjustment cavity 304 is used to adjust the relative position of the piston rod 303 within the cylinder 301. A connecting port 3031 is located between the piston section 3033 and the sealing plate 3034. A connecting cavity 3032 is formed between the piston section 3033 and the sealing plate 3034, corresponding to the second semicircular cavity. The connecting port 3031 is connected to a cooling pipe 302 in a designated area through the connecting cavity 3032. The connecting cavity 3032 corresponds to three cooling pipes 302, thus ensuring sufficient cooling area. The partition plate 305 completely separates the adjustment cavity 304 and the connecting cavity 3032, preventing the coolant inside from mixing and avoiding cross-contamination. The adjustment cavity 304 is used to inject or pump coolant to drive the piston rod 303 to slide, thus eliminating the need for an additional drive motor 204 or cylinder. The connecting port 3031 is always located in the connecting cavity 3032 between the piston part 3033 and the sealing plate 3034, so that no matter how the piston rod 303 slides, the relative position of the connecting port 3031 and the connecting cavity 3032 remains unchanged, ensuring the stability of the position of the connecting port 3031.

[0035] Furthermore, the cylinder 301 is provided with an adjustment port 3011, which communicates with the adjustment cavity 304. The control system can inject or pump coolant into the adjustment cavity 304 through the adjustment port 3011 according to the real-time swing position of the upper electrode plate 202, thereby changing the relative position of the piston rod 303 within the cylinder 301. This simple structure achieves movement control of the piston rod 303 through liquid injection or extraction. The adjustment port 3011 is located at one end of the cylinder 301. Figure 8 As shown in the figure, the direction indicated by the arrow is the flow direction of the coolant. The coolant enters through the liquid outlet 3012 of the piston rod 303 in one of the cylinders 301, then enters the cooling pipe 302 in the designated area through the connecting port 3031 and the connecting cavity 3032, and finally flows out from the liquid outlet 3012 of the piston rod 303 in the other cylinder 301.

[0036] Furthermore, both the piston portion 3033 and the sealing plate 3034 are provided with clearance grooves extending in the left-right direction, and the clearance grooves are in a sealing sliding fit with the partition plate 305. This allows the piston rod 303 to slide smoothly inside the cylinder 301, while preventing the adjusting cavity 304 from connecting with the communicating cavity 3032.

[0037] Specifically, the treatment bed 110 is equipped with a control panel 140, which is connected to the host 150 by a signal and is used to input operation commands to the host 150. The host 150 controls the operation of the drive motor 204, the hydraulic telescopic cylinder 130 and the linear drive cylinder 207 according to the operation commands.

[0038] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows: The patient lies supine on the treatment bed 110 and adjusts their position so that the area of ​​the body surface to be treated (i.e., treatment area 401) is located between the upper electrode plate 202 and the lower electrode plate. Then, a start signal is input through the control panel 140. Upon receiving the command, the host computer 150 controls the hydraulic telescopic cylinder 130 to move. The hydraulic telescopic cylinder 130 drives the lifting box 120 to slide vertically, coarsely adjusting the height of the upper electrode plate 202 to bring it closer to the body surface of the patient 400. Subsequently, the host computer 150 controls the linear drive cylinders 207 inside each T-shaped block 206 to precisely adjust the distance between the upper electrode plate 202, the lower electrode plate, and the body surface of the patient 400, until the pad 209 lightly touches or approaches the body surface of the patient 400, ensuring that the capacitive field effectively acts on the treatment area 401 while avoiding direct pressure from the electrode plates on the patient 400.

[0039] Subsequently, a treatment signal is input through the control panel 140, forming a capacitive field between the upper electrode plate 202 and the lower electrode plate. Simultaneously, the main unit 150 controls the drive motors 204 on each mounting plate 203 to operate. The upper drive motor 204, through the meshing of gear 205 and arc-shaped rack 2061, drives the upper swing arm 200 to slide along the upper arc-shaped groove 201; the lower drive motor 204 rotates in the opposite direction, driving the lower swing arm 500 to slide along the lower arc-shaped groove. Because the drive motors 204 corresponding to the upper swing arm 200 and the lower swing arm 500 are configured to rotate synchronously in opposite directions, the upper swing arm 200 and the lower swing arm 500 achieve synchronous counter-oscillation. Figure 4As shown, when the upper swing arm 200 swings to the right, it drives the upper electrode plate 202 to swing to the right synchronously; simultaneously, the lower swing arm 500 swings to the left, driving the lower electrode plate to swing to the left synchronously. During this process, the capacitive field formed between the upper electrode plate 202 and the lower electrode plate is always aligned with and surrounds the treatment area 401 on the surface of the human body 400. With the continuous swinging of the electrode plates, the capacitive field continuously moves within the treatment area 401, causing the heating position of the fat layer near the treatment area 401 to continuously change, avoiding prolonged heating of the same location, and achieving uniform and safe treatment.

[0040] While the upper electrode plate 202 is swinging for treatment, the control system acquires the instantaneous swing position of the upper electrode plate 202 in real time. Based on the acquired real-time position, the area of ​​the human body surface 400 just covered by the upper electrode plate 202 is determined as the "treated area," and the position of the cooling pipe 302 corresponding to the treated area is determined. The control system injects or draws coolant into the adjustment chambers 304 of the two cylinders 301 through the adjustment port 3011. For example, when it is necessary to move the piston rod 303 to the right ( Figure 8 When the piston rod moves away from the regulating port 3011, coolant is simultaneously injected into the regulating cavities 304 of both cylinders 301, increasing the pressure in the regulating cavities 304, pushing the sealing plate 3034, and causing the entire piston rod 303 to slide to the right. After the piston rod 303 slides to the target position, the connecting port 3031 moves with the piston rod 303 to the position corresponding to the cooling pipe 302 of the designated area, and connects with the cooling pipe 302 of the designated area through the connecting cavity 3032. Coolant enters the piston rod 303 from the liquid outlet 3012 at the end of the piston rod 303 in the cylinder 301, flows through the connecting port 3031 and the connecting cavity 3032, and then enters the cooling pipe 302 of the designated area to cool and lower the treated area. The coolant, after absorbing heat, then flows out from the liquid outlet 3012 of the piston rod 303 in the other cylinder 301, forming a complete cycle.

[0041] After the treatment time reaches the set value, the control system issues a command to stop the swinging of each drive motor 204, and the upper electrode plate 202 and lower electrode plate return to their initial positions. The linear drive cylinder 207 retracts, moving the upper electrode plate 202 and lower electrode plate away from the body surface 400. The hydraulic telescopic cylinder 130 retracts, causing the lifting box 120 to rise to its highest position, making room for the patient to leave the treatment bed 110. Finally, the patient stands up, and the treatment ends.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
