Description

Technical Field

[0001] The present invention complies with the technical field of physiotherapy instruments and aims to provide a multifunctional LED light low-frequency physiotherapy instrument. Background Art

[0002] The multifunctional LED light low-frequency physiotherapy device is a physiotherapy device that combines LED light therapy and low-frequency electrical stimulation technology, and can be selected according to different treatment needs. Among them, the abdominal belt-type LED light low-frequency physiotherapy device is specifically targeted at the abdominal area and can be used to help relieve abdominal pain, promote postpartum recovery, improve blood circulation, reduce muscle tension, etc.

[0003] Existing abdominal belt-type LED light low-frequency physiotherapy devices are usually composed of a cover plate, a physiotherapy component plate and a fitting plate. The fitting plate contacts the patient's skin and is fixed to the cover plate (the two sides are fixed to each other). The physiotherapy component plate is provided with an LED light therapy module and a low-frequency electrical stimulation module. The physiotherapy component plate is located between the cover plate and the fitting plate and is clamped by the cover plate and the fitting plate. However, during normal use, when patients of different weights wear it, the degree of bending of the fitting plate is different (the smaller the weight, the greater the degree of bending). When the fitting plate bends, the cover plate and the physiotherapy component plate will also bend. However, after the fitting plate and the cover plate are bent, the bent part in the middle of the two will separate, and then the pressing force on the physiotherapy component plate between the two will be lost, and even the fitting plate will lose contact with the physiotherapy component plate, resulting in the light and electric pulses emitted by the physiotherapy component plate unable to directly act on the fitting plate, thereby causing the physiotherapy effect to deteriorate.

DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0035] Example 1: A multifunctional LED light low-frequency physiotherapy device, such as Figures 1-6 As shown, it includes: a bonding plate 1, the front and rear sides of the bonding plate 1 are fixedly connected with a connecting piece 2, the connecting piece 2 is made of soft rubber, a plurality of low-frequency electrode points 101 are provided on the bonding plate 1, the connecting piece 2 is fixedly connected with a fixing plate 3, and the two fixing plates 3 are respectively located on the front and rear sides of the bonding plate 1; a physiotherapy plate 4, which is provided on the bonding plate 1, and a plurality of LED light sources 402 are provided on the physiotherapy plate 4; in this solution, the plurality of low-frequency electrode points 101 are divided into four groups (one group is on the same horizontal line); a cover plate 5, which is provided on The laminating plate 1 is in contact with the physiotherapy plate 4. The laminating plate 1 and the fixing plate 3 are plugged and fixed to each other with the cover plate 5, so that the three are in a relatively fixed state. The physiotherapy plate 4 is located between the laminating plate 1 and the cover plate 5; the limiting pins 6 have several ones, which are all fixed to the physiotherapy plate 4 and are slidably connected to the laminating plate 1. The low-frequency electrode point 101 is aligned with the projection of the adjacent limiting pin 6 in the horizontal direction. The limiting pin 6 is composed of a sphere and a round rod. The round rod is slidably connected to the fixing plate 3. The position of the limiting pin 6 in this scheme The position of the adjacent low-frequency electrode point 101 corresponds to that of the adjacent low-frequency electrode point 101, so as to adjust the position of the bonding plate 1 close to the adjacent low-frequency electrode point 101; the limiting grooves 7, the number of which is consistent with the number of the limiting pins 6, are all provided on the bonding plate 1, the limiting pins 6 and the limiting grooves 7 are limited and matched, and the ball of the limiting pin 6 slides in the limiting grooves 7, and all the limiting grooves 7 are symmetrically distributed front and back with the central axis of the bonding plate 1 as the standard; the stabilizing components, the number of which is consistent with the number of the low-frequency electrode points 101, are all provided on the physiotherapy board 4, and are used In order to strengthen the connection between the bonding plate 1 and the physiotherapy plate 4, the limiting groove 7 has a first horizontal portion 701, an inclined portion 702 and a second horizontal portion 703, and the inclined portion 702 is located between the first horizontal portion 701 and the second horizontal portion 703. In the initial state, the limiting pin 6 is located at the second horizontal portion 703. The limiting groove 7 also has an arc portion 704, which facilitates the limiting pin 6 to enter or move out of the limiting groove 7. The arc portion 704 is located on the side of the second horizontal portion 703 away from the inclined portion 702.

[0036] A control terminal is externally connected to the laminating plate 1 (which is an existing structure, such as a control tablet, not shown in the figure). The control tablet on the laminating plate 1 is used to control the opening and closing of the low-frequency electrode point 101. After the control tablet energizes the low-frequency electrode point 101 on the laminating plate 1, the low-frequency electrode point 101 emits a low-frequency electric pulse, which is transmitted to the skin and muscle tissue through the electrode to treat the patient; the physiotherapy board 4 is connected to the control tablet through a line, and the control tablet can also control the opening or closing of the LED light source 402. After the control tablet energizes the LED light source 402 on the physiotherapy board 4, the LED light source 402 releases the light source, and the patient is given light therapy through light sources of different wavelengths.

[0037] In this solution, the low-frequency electrode point 101 and the LED light source 402 are installed in different positions respectively, so that when the patient needs low-frequency electrotherapy, only the bonding plate 1 can be in contact with the skin to complete the low-frequency electrotherapy; similarly, when the patient needs LED light therapy, only the physical therapy plate 4 can be tied to the skin to complete the LED light therapy; at the same time, the patient can also combine the bonding plate 1 and the physical therapy plate 4 together so that the two work at the same time, thereby completing the low-frequency electrotherapy and LED light therapy at the same time; during the use of this device, the bonding plate 1 and the physical therapy plate 4 are both made of existing soft materials, which can be appropriately bent according to the different needs of the patient, and the bonding plate 1 and the physical therapy plate 4 can be placed in different target positions (such as the abdomen, legs, waist and other parts of the body) to increase the applicability of this device.

[0038] When the patient uses the device according to the above conditions, when the patient treats different parts of the body, the patient can control the range and number of the low-frequency electrode points 101 and the LED light source 402 that are turned on through the control tablet, so as to ensure accurate operation on the treatment position required by the patient. At the same time, the patient can adjust the intensity of the low-frequency electrode points 101 and the LED light source 402 according to their own conditions (that is, the intensity of the electric pulses emitted by the low-frequency electrode points 101 or the light intensity emitted by the LED light source 402, and the control tablet is provided with intensity levels of the low-frequency electrode points 101 and the LED light source 402), so as to adjust different modes according to the different needs of the patient, so that the device can adapt to different patients and the different needs of patients, thereby increasing the applicability of the device.

[0039] The control tablet can also control the different working states of the low-frequency electrode point 101 and the LED light source 402, such as controlling the low-frequency electrode point 101 to work intermittently or continuously, and controlling the LED light source 402 to work intermittently or continuously. The control tablet is provided with buttons for the above-mentioned different modes, and patients can make corresponding adjustments according to different needs.

[0040] When using the device for physical therapy, the user puts the bonding plate 1 on the skin to bend the bonding plate 1. Similarly, the connecting piece 2, the fixing plate 3 and the cover plate 5 will also bend. The bonding plate 1 and the cover plate 5 jointly drive the physical therapy plate 4 to bend. Since the two fixing plates 3 and the cover plate 5 are in a fixed state, the two cannot be misaligned with each other, which causes the bent part of the bonding plate 1 to bulge, and thus the bonding plate 1 cannot fully contact the physical therapy plate 4. To avoid this situation, the specific process is as follows:

[0041] For ease of understanding, the following description is based on Figure 6The direction shown is based on this. During the downward bending process of the bonding plate 1, the bonding plate 1 drives the limit groove 7 thereon to move, and the limit groove 7 drives the upper limit pin 6 thereon to move. During the bending process, the distance between the two fixed plates 3 is reduced, and the corresponding limit pins 6 on the left and right are brought closer to each other, so that the limit pin 6 slides along the second horizontal portion 703 to the inclined portion 702. During the sliding process of the limit pin 6, the limit pin 6 gradually penetrates into the limit groove 7, and the limit pin 6 drives the adjacent position of the therapy plate 4 to be close to the bonding plate 1. As the bonding plate 1 bends, the limit pin 6 gradually enters the first horizontal portion 701 from the inclined portion 702.

[0042] During the movement of the limit pin 6, the limit pin 6 drives the bonding plate 1 to move close to the position of the adjacent low-frequency electrode point 101, thereby ensuring that the therapy plate 4 is fully fitted with the bonding plate 1, and at the same time ensuring that the low-frequency electrode point 101 and the LED light source 402 play their full role, preventing the therapy plate 4 from separating from the bonding plate 1. At the same time, the greater the degree of bending of the bonding plate 1, the greater the length of the limit pin 6 entering the limit groove 7, and the stronger the fit between the therapy plate 4 and the bonding plate 1.

[0043] After the device is installed, the user turns on the main power supply to start all the low-frequency electrode points 101 and the LED light source 402 to work. After the laminating plate 1 comes into contact with the user's skin, the physical therapy operation begins.

[0044] After using the device, the user first removes the device and then restores the bonding plate 1 to a flat state. During this process, the limit pin 6 gradually moves from the first horizontal portion 701 to the inclined portion 702 and then to the second horizontal portion 703, thereby completing the reset of the limit pin 6, that is, the therapy plate 4 returns to its initial state.

[0045] When separating the laminating plate 1 from the therapy plate 4, the user bends the laminating plate 1 upwards ( Figure 6 As shown), at this time, the distance between the two symmetrical limit grooves 7 is reduced, and the limit groove 7 squeezes the limit pin 6, causing the limit pin 6 to slide along the second horizontal portion 703 and move toward the arc portion 704. Subsequently, the limit pin 6 moves into the arc portion 704, and the arc portion 704 guides the limit pin 6, causing the limit pin 6 to move upward, thereby causing the limit pin 6 to disengage from the limit groove 7, and the limit pin 6 drives the physiotherapy board 4 to move upward, thereby causing the physiotherapy board 4 to lose contact with the bonding plate 1, thereby completing the rapid disassembly of the physiotherapy board 4, improving the use efficiency of the device, and when the physiotherapy board 4 is installed on the bonding plate 1, the bonding plate 1 and the two fixed plates 3 are also bent upward so that the arc portion 704 corresponds to the limit pin 6, thereby causing the limit pin 6 to enter the limit groove 7, thereby completing the rapid installation of the physiotherapy board 4.

[0046] like Figure 3 、 Figure 4 and Figure 7-Figure 9 As shown, the stabilizing component includes: a mounting shell 401, the number of which is consistent with the low-frequency electrode point 101, and both are fixed to the therapy board 4; electromagnetic elements 41, the number of which is consistent with the mounting shell 401, and both are slidably connected to the therapy board 4, the electromagnetic element 41 is magnetically matched with the bonding plate 1, and the electromagnetic element 41 is located in the mounting shell 401; initially, the upper side of the electromagnetic element 41 is not in contact with the mounting shell 401, and the electromagnetic element 41 is an electromagnet. After being energized, it generates magnetism by itself and adsorbs the bonding plate 1, further strengthening the tightness between the bonding plate 1 and the therapy board 4; electric coils 42, the number of which is consistent with the electromagnetic elements 41, are both arranged on the therapy board 4, and are electrically connected to the adjacent electromagnetic elements 41, and the electric coils 42 are wound around the outside of the electromagnetic element 41; contact slots 43, the number of which is consistent with the mounting shell 401, are both arranged on the bonding plate 1, and the mounting shell 401 It contacts and cooperates with the adjacent contact groove 43. After the physiotherapy board 4 is fitted with the bonding plate 1, the mounting shell 401 is located in the contact groove 43 and contacts with the bonding plate 1. The diameter of the mounting shell 401 is smaller than the inner diameter of the contact groove 43. When the physiotherapy board 4 and the bonding plate 1 are bent, the mounting shell 401 can slide in the contact groove 43. The electromagnetic element 41 is fixed with circumferentially distributed elastic parts 44. The elastic parts 44 are springs. The circumferentially distributed elastic parts 44 are used to keep the position of the electromagnetic element 41 stable and are located at the center of the mounting shell 401. The elastic part 44 is fixed to the physiotherapy board 4. The physiotherapy board 4 is provided with inclined surfaces 45 with the same number as the electromagnetic elements 41. The inclined surfaces 45 are squeezed and matched with the adjacent electromagnetic elements 41. When the electromagnetic element 41 slides, the inclined surfaces 45 squeeze the electromagnetic element 41 to reduce the distance between the electromagnetic element 41 and the mounting shell 401.

[0047] When using this device, the user turns on the main power supply and allows current to pass through the electric coil 42, thereby causing the electromagnetic element 41 to generate magnetism. At this time, the electromagnetic element 41 attracts the bonding plate 1, thereby improving the bonding effect between the bonding plate 1 and the physical therapy plate 4, and ensuring the stability between the bonding plate 1 and the physical therapy plate 4.

[0048] After the bonding plate 1 and the physiotherapy plate 4 are bent, the bonding plate 1 and the physiotherapy plate 4 slide relative to each other. During this process, the mounting shell 401 slides in the contact groove 43. Due to the magnetic force between the electromagnetic element 41 and the bonding plate 1, the electromagnetic element 41 does not move relative to the bonding plate 1, that is, the electromagnetic element 41 is in a fixed state, and the electromagnetic element 41 and the mounting shell 401 move relative to each other. The electromagnetic element 41 squeezes the adjacent elastic member 44. During this process, after the electromagnetic element 41 contacts the inclined surface 45, the inclined surface 45 squeezes the electromagnetic element 41, causing the electromagnetic element 4 to move upward, thereby reducing the distance between the upper side of the electromagnetic element 41 and the mounting shell 401, and then reducing the distance between the electromagnetic element 41 and the bonding plate 1. In this way, the adsorption force of the electromagnetic element 41 on the bonding plate 1 is increased, further improving the stability between the bonding plate 1 and the physiotherapy plate 4, and avoiding the bonding plate 1 and the physiotherapy plate 4 from losing contact.

[0049] Example 2: Based on Example 1, Figure 1 and Figure 11-14 As shown, it also includes: a fixing mechanism, which is arranged on the cover plate 5 and is used to fix the laminating plate 1 and the physiotherapy plate 4. The fixing mechanism includes: a first belt 71, which is arranged on the cover plate 5 and is in contact with and matched with the adjacent fixing plate 3 and physiotherapy plate 4. After the fixing plate 3, the physiotherapy plate 4 and the cover plate 5 are laminated to each other, the user wraps one end of the first belt 71 around one side of the physiotherapy plate 4 and the cover plate 5 and the adjacent fixing plate 3; a second belt 72, which is arranged on the adjacent first belt 71; a third belt 73, which is arranged on the cover plate 5 and is in contact with and matched with the adjacent fixing plate 3 and physiotherapy plate 4. After the fixing plate 3, the physiotherapy plate 4 and the cover plate 5 are laminated to each other, the user uses The person wraps one end of the third belt 73 around the other side of the therapy board 4 and the cover plate 5 and the adjacent fixed plate 3; the mounting shell 74 is fixedly connected to the second belt 72, and the third belt 73 passes through the mounting shell 74; the limiting frame 75 is slidably connected to the mounting shell 74, and a spring is provided between the two, the limiting frame 75 and the third belt 73 are limited and matched, and a plurality of grooves are provided on the side of the third belt 73 close to the mounting shell 74. The limiting frame 75 is inserted into the adjacent grooves, so that the third belt 73 and the second belt 72 become a whole; the adjustment component is provided between the first belt 71 and the second belt 72, and is used to control the distance between the first belt 71 and the second belt 72.

[0050] After wrapping one end of the first belt 71 and one end of the third belt 73 to the adjacent sides of the cover plate 5 respectively, the user pushes the limit frame 75 upwards and compresses the spring, and then passes the other end of the third belt 73 into the mounting shell 74. The third belt 73 passes from the lower side of the limit frame 75 until the device is fixed to the user's abdomen. The user releases the limit frame 75, and the limit frame 75 contacts the third belt 73 under the action of the spring and is stuck in the groove of the third belt 73, thereby completing the fixation of the device.

[0051] like Figure 11 、 Figure 13 and Figure 14 As shown, the adjustment component includes: an adjustment shell 81, which is slidably connected to the first belt 71 and slidably connected to the second belt 72. The first belt 71 and the second belt 72 are connected together through the adjustment shell 81. After the device is fixed, the adjustment shell 81 is in the middle position (that is, at this time, the length of the first belt 71 is equal to the sum of the length of the part of the second belt 72 that fits the user and the length of the part of the third belt 73 that fits the user); a rotating rod 82, which is rotatably connected to the adjusting shell 81, and a spur gear is fixed to the rotating rod 82; a first rack 83, which is fixed to the second belt 72 and meshes with the spur gear of the rotating rod 82; a second rack 84, which is fixed to the first belt 71 and meshes with the spur gear of the rotating rod 82; a limit assembly, which is arranged on the adjustment shell 81 and is used to control the movement of the rotating rod 82.

[0052] After the limit frame 75 is inserted into the groove of the third belt 73, when the user adjusts the tightness, the user first operates the limit assembly to release the limit on the rotating rod 82, and then the user adjusts the rotating rod 82, and the rotating rod 82 drives the spur gear thereon to rotate, and the spur gear drives the second rack 84 and the first rack 83 to move synchronously, so that the second rack 84 and the first rack 83 are synchronously approached or synchronously moved away, and then the first belt 71 and the second belt 72 are moved away from each other or close to each other. Through the transmission between the second rack 84 and the first rack 83 and the spur gear, the first belt 71 and the second belt 72 move synchronously and move the same distance, so as to avoid the adjustment of one of the first belt 71, the second belt 72 and the third belt 73 causing the fitting plate 1 and the physiotherapy plate 4 to be offset, affecting the physiotherapy effect.

[0053] like Figure 14 As shown, the limit assembly includes: a control rod 91, which is slidably connected to the adjustment housing 81, and a tension spring is provided between the two, the tension spring is used to drive the control rod 91 to reset, and the control rod 91 is fixed with a limit tooth; a limit gear 92, which is fixed to the rotating rod 82, and the limit gear 92 is limited by the upper limit tooth of the control rod 91. After the limit tooth contacts the limit gear 92, the limit tooth limits the limit gear 92, so that the rotating rod 82 cannot rotate.

[0054] When the user wants to adjust the length between the first belt 71 and the second belt 72, the user first presses the control lever 91, the tension spring of the control lever 91 is stretched, and the control lever 91 drives the limit tooth to move, and the limit tooth loses contact with the limit gear 92, so that the limit gear 92 can rotate freely. Then the user rotates the rotating rod 82 to adjust the distance between the first belt 71 and the second belt 72. After the adjustment is completed, the user releases the control lever 91, and the control lever 91 is reset under the action of the tension spring, and the limit tooth is re-contacted with the limit gear 92, thereby making the rotating rod 82 unable to rotate. The limit tooth is used to limit the gear 92 to prevent the rotating rod 82 from rotating at will during normal use, which causes the length of the first belt 71, the second belt 72 and the third belt 73 to change, thereby causing the device to fall off during use.

[0055] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.
