Description

Multi-probe ultra-shortwave intelligent physiotherapy device Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, and in particular to a multi-probe ultra-shortwave intelligent physiotherapy device. Background Technology

[0002] Ultrashortwave therapy is a traditional physiotherapy instrument that uses electron tube oscillation to generate an ultrashortwave high-frequency electric field for physiotherapy. Radiofrequency current with wavelengths of 1–10 m and frequencies of 30–300 MHz is generally referred to as ultrashortwave current, and its clinical application is called ultrashortwave therapy. In Europe and America, because the distinction between shortwave and ultrashortwave is not well defined, it is generally referred to as shortwave or radiofrequency. Most devices output energy through capacitive electrodes. The affected area is placed between the electrodes, and under the influence of the high-frequency electric field, the molecules and ions in the lesion vibrate in parallel positions and rub against each other, generating a thermal effect. This thermal effect evenly heats the superficial and deep tissues of the affected area, enhancing vascular permeability, improving microcirculation, regulating endocrine function, strengthening the body's metabolism, and reducing the excitability of sensory nerves. This achieves the therapeutic goals of antibacterial, anti-inflammatory, analgesic, antispasmodic, blood circulation and repair, and enhanced immunity.

[0003] Due to its painless, hygienic, and convenient operation, shortwave diathermy is widely used. To achieve better therapeutic effects, researchers in this field have developed both horizontal and vertical shortwave diathermy devices. Horizontal devices offer greater comfort. Existing horizontal microwave diathermy devices include a controller, bed, shortwave generator, and probes. The shortwave generator is the core component and is manufactured in many countries worldwide, such as PRS-9000 (Chattanooga, USA), MED-1500-Enraf ​​(Nonius, Netherlands), T-5 (EMS Physio, UK), SR-500 (Electronics AB, Sweden), and MEA-300 (MECTRON, Italy). These devices can stably output shortwave diathermy, which is applied to predetermined locations on the body (usually acupoints) via probes. For ease of use, researchers in this field have also developed horizontal shortwave diathermy devices with multiple probes, allowing simultaneous treatment at different locations.

[0004] In some cases, multi-probe shortwave physiotherapy devices include a bed with multiple cantilever arms installed on the side of the bed. Probes are installed at the ends of the cantilever arms, allowing each probe to be positioned independently. The cantilever arms are foldable, enabling operation of the cantilever arms to coordinate the probes with the body parts to be treated, which is convenient for operation. However, it is not possible to achieve simultaneous operation of multiple probes, resulting in a low level of intelligence.

[0005] Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-probe ultra-shortwave intelligent physiotherapy device that enables multiple probes to operate simultaneously.

[0007] This invention is achieved through the following technical solution: a multi-probe ultra-shortwave intelligent physiotherapy device, including a controller and a bed, a flipping frame is provided on the side of the bed, multiple support rods are provided on the flipping frame, ultra-shortwave physiotherapy probes are provided at the ends of the support rods, any ultra-shortwave physiotherapy probe is connected to an opening and closing control device, the flipping frame is connected to a flipping drive device, the flipping frame can be flipped so that the ultra-shortwave physiotherapy probes are in conjunction with the human body, and any support rod is connected to a length adjustment device.

[0008] In one embodiment, the flipping frame includes a rotating cylinder disposed on the side wall of the bed, and the flipping drive device includes a drive motor connected to the rotating cylinder. The drive motor drives the rotating cylinder to rotate at an angle of 65°-100°, and the cable of the ultra-shortwave therapy probe passes through the rotating cylinder.

[0018] 1. A flipping frame is installed, with multiple support rods mounted on it. Ultra-shortwave therapy probes are installed at the ends of the support rods. The flipping frame can be flipped so that the ultra-shortwave therapy probes are in sync with the human body, thereby achieving the purpose of synchronously driving the movement of multiple probes. Each support rod is connected to a length adjustment device, which can adjust the length of the support rod before flipping, and thus adjust the position of the ultra-shortwave therapy probe according to the human body shape. Each ultra-shortwave therapy probe is connected to an opening and closing control device, which can select the ultra-shortwave therapy probe to work according to preset values, achieving the purpose of intelligent control.

[0019] 2. The flipping frame includes a rotating cylinder installed on the side wall of the bed. The rotation angle of the rotating cylinder is 65°-100°.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] As shown in Figure 1-11, a multi-probe ultra-shortwave intelligent physiotherapy device includes a controller and a bed 3. The controller is installed on the control console 1 and connected to a touch screen, which allows data input. A detection platform 4 is also installed on one side of the bed 3. The detection platform 4 detects the upper body length, width, and thickness of the human body, as well as detects whether there is metal at the location of the human body to be treated with ultra-shortwave physiotherapy. After the detection is completed, the upper body length, width, and thickness data are input into the controller through the touch screen, and the treatment area is selected through the touch screen.

[0038] A tilting frame 5 is installed on the side of the bed frame 3. The tilting frame 5 is connected to a tilting drive device. In this embodiment, the tilting frame 5 includes a rotating cylinder 7 installed on the side wall of the bed frame 3. The side of the bed frame 3 has a pre-reserved mounting groove for the rotating cylinder 7, thus partially concealing the rotating cylinder 7 for aesthetic and safety purposes. The tilting drive device includes a drive motor 8 connected to the rotating cylinder 7. The drive motor 8 is a servo motor, which can control the rotation angle. The drive motor 8 drives the rotating cylinder 7 to rotate at an angle of 65°-100°. Under normal conditions, the support rod 11 and the ultra-shortwave therapy probe 12 are tilted to the side to avoid interfering with the person lying down on the bed frame 3. During operation, the tilting frame 5 can tilt. The ultra-shortwave therapy probe 12 is designed to fit the human body to accommodate its thickness. The cable 6 of the ultra-shortwave therapy probe 12 passes through the rotating cylinder 7, providing space for the cable 6 to extend and retract. The drive motor 8 is connected to the transmission shaft 14, which is connected to the side of the bed 3 via a bearing seat to position the rotating cylinder 7. Multiple support rods 11 are connected to the rotating cylinder 7, and ultra-shortwave therapy probes 12 are installed at the ends of the support rods 11, thereby controlling the simultaneous movement of multiple ultra-shortwave therapy probes 12. During the design process, an attempt was made to use a lifting frame to control the simultaneous movement of multiple ultra-shortwave therapy probes 12, which has high control precision but is prone to interfering with the human body lying on the bed 3.

[0039] In this embodiment, the support rod 11 is made of galvanized pipe, which has good resistance to deformation, thus avoiding positional deviation of the ultra-shortwave therapy probe 12 caused by deformation of the support rod 11. Bending the support rod 11 into an arc shape using a pipe bending machine further improves its resistance to deformation. The cable 6 of the ultra-shortwave therapy probe 12 passes through the support crossbar. Multiple ultra-shortwave therapy probes 12 correspond to different treatment areas. Each support rod 11 is connected to a length adjustment device to adapt to different body types. Since the recipients of the therapy are usually adults, and the treatment area is usually acupoints... For the upper body, where there are many treatment areas, the positional deviation of the same treatment area is small for different individuals, usually with proportional changes. In this embodiment, the length adjustment device includes an adjustment cylinder 9 fixed to the upper end of the rotating cylinder 7. The adjustment cylinder 9 is parallel to the rotating cylinder 7. A second drive shaft 15 is installed inside the adjustment cylinder 9. The second drive shaft 15 is connected to a second drive motor 10, which is also a servo motor. Multiple adjustment wheels 16 are installed on the second drive shaft 15. The number of adjustment wheels 16 corresponds to the number of support rods 11. The support rods 11 are connected to flexible hoses 18 that cooperate with the adjustment wheels 16. 11 is connected to a reset device. In this embodiment, the reset device includes a snap-fit ​​component mounted on the adjusting wheel 16. The flexible hose 18 is fixedly connected to the snap-fit ​​component. Specifically, the snap-fit ​​component is fixed to the pressure plate 20 on the adjusting wheel 16 by bolts, thereby causing the flexible hose 18 to bend and deform during the rotation of the adjusting wheel 16, which drives the support rod 11 to extend and retract. During the reset process of the adjusting wheel 16, the support rod 11 is reset. A guide cylinder 13 that cooperates with the cable 6 of the ultra-shortwave therapy probe 12 is installed on the drive shaft 14. During the rotation of the rotating cylinder 7, the guide cylinder 13 passes through the cable 6. The friction between 6 makes the cable 6 synchronize with the guide cylinder 13, thereby reducing the tension of the cable 6 at the lower end of the guide cylinder 13 on the adjusting wheel 16. The adjusting wheel 16 is machined with a guide groove 19 that cooperates with the hose 18. By selecting the outer diameter value of the adjusting wheel 16 or the depth value of the guide groove 19, the extension and retraction stroke of the support rod 11 can be controlled to adapt to the size deviation of the same physiotherapy part of different human bodies. The guide groove 19 is set at an angle, and the support rod 11 swings during the driving action of the hose 18, thereby adapting to the width of the human body and the length of the upper body.

[0040] The upper end of the adjusting cylinder 9 is machined with a groove 17 that mates with the support rod 11, allowing the support rod 11 to swing to adapt to the length of the human upper body. A slider that mates with the groove 17 is installed on the support rod 11, and a positioning device that mates with the groove 17 is installed on the slider. Specifically, the slider includes a sliding frame 21, on which a friction wheel 23 that mates with the support rod 11 is installed. The main shaft of the friction wheel 23 is fixedly connected to a drive roller 22. The rotation of the friction wheel 23 can drive the drive roller 22 to rotate, thereby causing the sliding frame 21 to slide. In conjunction with the hose 18, this increases the driving force for the swing of the support rod 11. The part where the support rod 11 mates with the friction wheel 23 is straight. The surface of the friction wheel 23 is covered with a rubber layer to increase friction. The drive roller 22 mates with the upper end face of the slide groove 17 to form a positioning device. A guide wheel 24 that mates with the friction wheel 23 is also installed on the sliding frame 21. The main shaft of the guide wheel 24 is connected to the driven roller. The main shaft of the guide wheel 24 and the driven roller are rotatably connected. The torque of the guide wheel 24 is not transmitted to the driven roller. The guide wheel 24 positions the support rod 11 so that the support rod 11 and the friction wheel 23 are pressed together. A cover can also be installed on the outside of the sliding frame 21 to achieve an aesthetic effect.

[0041] Each shortwave therapy probe 12 is connected to an opening and closing control device. In this embodiment, the opening and closing control device is a relay, which is connected to a controller. The shortwave therapy probe 12 includes an outer cover 28, and a working head 29 is installed inside the cover. The working head 29 emits shortwave waves to the area to be treated. An angle buffer device is installed between the shortwave therapy probe 12 and the support rod 11. The angle buffer device includes an adjustment seat installed at the end of the support rod 11. The shortwave therapy probe 12 is connected to the adjustment seat. In this embodiment, the adjustment seat is a bent tube 27, which is an aluminum tube. The outer cover 28 is connected to the support rod 11 through the bent tube 27. The bending tube 27 is 3cm-4cm long, which can provide stable support for the ultra-shortwave therapy probe 12 and can be bent under external force to adjust the orientation of the ultra-shortwave therapy probe 12. The angle buffer device includes a buffer sleeve 31 installed at the lower end of the cover. The buffer sleeve 31 is a silicone sleeve with a thickness of 3mm-4mm, which can play a good buffering role and can also play a heat insulation role during use, so that heat is concentrated during ultra-shortwave therapy. A pressure sensor 32 is installed on the lower end face of the buffer sleeve 31 to detect pressure and avoid injury to the human body. The pressure sensor 32 is connected to the controller.

[0042] The ultra-shortwave therapy probe 12 is connected to a temperature sensor 30, which is connected to a controller to detect the temperature during the ultra-shortwave therapy process.

[0043] It also includes a display stand 2, on which a display screen is installed to show treatment information to the person receiving ultra-shortwave therapy. The treatment information includes the treatment area, key points to note during the treatment process, and the treatment progress.

[0044] The steps for using the multi-probe ultra-shortwave intelligent physiotherapy device provided in this embodiment are as follows:

[0045] The detection station 4 detects the upper body length, width, and thickness of the person receiving ultra-shortwave therapy, as well as the presence of metal at the location to be treated. The upper body length, width, and thickness data are input into the controller via a touch screen. The area to be treated with ultra-shortwave therapy is selected via the touch screen. Based on the upper body length value, the controller controls the drive motor 10 to move, which in turn moves the support rod 11, so that the ultra-shortwave therapy probe 12 reaches the predetermined position. During this process, the body length and width are assumed to be proportional, and the initial position is set to 120cm. The ultra-shortwave therapy area is selected according to the individual's condition.

[0046] Once the person undergoing shortwave therapy is lying or prone in the predetermined position on the bed 3, the controller controls the drive motor 8 to rotate according to the thickness of the human body, causing the shortwave therapy probe 12 to rotate with the rotating cylinder 7 to fit the human body. The pressure sensor 32 detects the pressure, and when the pressure reaches the preset value, the drive motor 8 stops to avoid excessive pressure that could damage the human body. After the drive motor 8 has completed its operation, the controller controls the relay to activate the corresponding shortwave generator, which in turn activates the corresponding working head 29. The temperature sensor 30 monitors the temperature at the therapy position.

[0047] After the predetermined duration is reached, the controller uses a relay to stop the corresponding ultra-shortwave generator from working. Then, drive motor 18 is reset, and drive motor 210 is reset again, thus completing the ultra-shortwave therapy. The therapy is completed automatically after the parameters are set, demonstrating a high degree of intelligence.

[0048] Example 2

[0049] As shown in Figure 12, a multi-probe ultra-shortwave intelligent physiotherapy device differs from Embodiment 1 in that the reset device includes a clamping wheel 26 that cooperates with the adjusting wheel 16. The purpose of controlling the extension and retraction stroke of the support rod 11 is achieved by selecting the outer diameter value of the adjusting wheel 16. A support shaft 25 parallel to the transmission shaft 15 is installed inside the adjusting cylinder 9. The clamping wheel 26 and the support shaft 25 are connected by a bearing. A clamping groove that cooperates with the guide groove 19 is machined on the clamping wheel 26 to improve the swing driving force of the support rod 11. The disadvantage is that a larger size is required to install the support shaft and the clamping wheel 26.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
