Detailed Implementation
[0037] The core of this invention is to provide a capacitive electrode device for wearable shortwave therapy devices. This capacitive electrode device for wearable shortwave therapy devices is easy to use and has a high therapeutic effect and user experience.
[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Please refer to Figures 1 to 8 A schematic diagram of the capacitive electrode device used in wearable shortwave therapy devices and schematic diagrams of each component.
[0040] In one specific embodiment, the capacitive electrode device for wearable shortwave therapy provided by this utility model includes an output line connector 1, a capacitive electrode plate 4 connected to the output line connector 1 via an output line 2, and an electrode plate support 5 for mounting the capacitive electrode plate 4. The capacitive electrode plate 4 includes a copper mesh plate 402 built into a protective chamber and a connecting plate 401 mounted on and electrically connected to the copper mesh plate 402. The connecting plate 401 is connected to the output line 2. The output line connector 1 includes an output line pin 101 connected to the output line housing 103, and the output line pin 101 is inserted into the socket of the main unit's female connector. It also includes a continuity judgment mechanism for determining whether the output line pin 101 is properly connected to the socket.
[0041] In the above structure, the capacitive electrode device used in the wearable shortwave therapy device includes an output line connector 1, a capacitive electrode plate 4, an electrode plate support 5, and a continuity judgment mechanism.
[0042] The capacitive electrode plate 4 is mounted on the electrode plate support 5. The copper mesh plate 402 is made of copper mesh material, which allows for flexible fit to the treatment area. The capacitive electrode plate 4 includes a protective chamber, a copper mesh plate 402, and a connecting plate 401. The copper mesh plate 402 and the connecting plate 401 are built into the protective chamber. The connecting plate 401 is mounted on the copper mesh plate 402, overlapping with the copper mesh plate 402, and is electrically connected to the copper mesh plate 402. The connecting plate 401 is connected to the other end of the output line 2, and the output line connector 1 is connected to one end of the output line 2, thereby connecting the capacitive electrode plate 4 to the output line connector 1. The copper mesh plate 402 is connected to the output line 2 via a connecting plate 401. The connecting plate 401 is connected to both the output line 2 and the copper mesh plate 402. The connecting plate 401 is made of copper and is harder than the copper mesh plate 402. The connection position between the connecting plate 401, the copper mesh plate 402, and the output line 2 is fixed, making it less prone to loosening or pulling, and the connection is firm. In addition, the connection area between the connecting plate 401 and the copper mesh plate 402 is large, resulting in good contact and preventing loose connections.
[0043] The output connector 1 includes an output cable housing 103 and an output cable pin 101. The output cable housing 103 is made of insulating material such as plastic, and the output cable pin 101 is connected to the output cable housing 103. The host socket has a socket, and the output cable pin 101 is inserted into the socket, connecting the capacitor electrode device to the host. A continuity judgment mechanism is used to determine whether the output cable pin 101 is properly connected to the socket. If the output cable connector 1 is properly connected to the host socket, the continuity judgment mechanism forms a circuit and sends a continuity signal; if the output cable connector 1 is not properly connected to the host socket or is detached, the continuity judgment mechanism forms an open circuit. This enables the host to monitor the contact of the output connector, promptly detect contact faults between the output cable connector 1 and the host socket, and avoid problems such as detachment or inadequate contact that go undetected during use.
[0044] Based on the above specific embodiments, the continuity determination mechanism includes:
[0045] The detection pin 102 is connected to the output line housing 103;
[0046] A detection port is located on the host female connector at a position that mates with the detection pin 102;
[0047] A continuity judgment unit connected to the detection pin 102, used to determine that the output line pin 101 is not properly connected to the socket when the detection pin 102 is not connected to the detection socket.
[0048] In practical applications, the detection pin 102 is connected to the output line housing 103. The main unit's female connector has a detection port, positioned opposite to the detection pin 102. When the output line pin 101 is inserted into the socket and makes normal contact, the detection pin 102 and the detection port are in contact and conduct, forming a circuit. When the output line pin 101 is inserted into the socket but not in normal contact, the detection pin 102 and the detection port are not in contact and conduct, thus forming an open circuit. The continuity judgment unit is connected to the detection pin 102. The detection pin 102 sends a continuity signal to the continuity judgment unit. When the detection pin 102 and the detection port are not in contact, it is determined that the output line pin 101 is abnormally connected to the socket; when the detection pin 102 and the detection port are in contact, it is determined that the output line pin 101 is normally connected to the socket.
[0049] In the above embodiment, the continuity signal between the detection pin 102 and the detection socket is used to determine whether the output line pin 101 is plugged into the socket, that is, to determine whether the capacitor electrode device is connected to the host. This achieves automatic judgment, which is accurate and fast, so as to detect and eliminate connection faults in a timely manner.
[0050] In a preferred embodiment, the continuity judgment unit is connected to the alarm unit. When the continuity judgment unit determines that the output line pin 101 is not properly connected to the socket, the alarm unit issues an alarm message to remind the operator to reconnect the output line connector 1 to the host socket and resolve the connection fault. The alarm unit can be a broadcast device or / and a warning light, emitting a clear warning signal.
[0051] Based on the above specific embodiments, the number of detection pins 102 is at least two. The continuity judgment unit is used to determine that the output line pin 101 is abnormally connected to the socket when at least one detection pin 102 is not connected to the detection socket.
[0052] In practical applications, at least two detection pins 102 simultaneously detect whether the output line pin 101 is properly connected to the socket, and both conduction judgment units send signals indicating whether the detection pins 102 and the detection socket are conductive. The conduction judgment unit determines that the output line pin 101 is properly connected to the socket when all detection pins 102 and the detection socket are conductive; it determines that the output line pin 101 is abnormally connected to the socket when one or more detection pins 102 are not conductive. In other words, as long as one detection pin 102 is detected as not conductive, it can be determined that the output line pin 101 is abnormally connected to the socket.
[0053] In the above embodiments, multiple detection pins 102 simultaneously detect the connection status of the output line pin 101 and the socket, ensuring that the output line connector 1 and the host socket are in flat contact, eliminating the illusion of false connection caused by the tilted connection of the output line connector 1 and the host socket.
[0054] Based on the above specific embodiments, the end of the detection pin 102 is flush with the surface of the output line housing 103, the output line pin 101 extends out of the surface of the output line housing 103, when the output line connector 1 is connected to the host female, the output line pin 101 is first connected to the socket, after the output line pin 101 is aligned with the socket and connected for a period of time, the detection pin 102 is then connected to the detection socket.
[0055] In one specific embodiment, the connection positions and relative lengths of the detection pin 102 and the output pin 101 to the output cable housing 103 are different. The output pin 101 extends beyond the surface of the output cable housing 103 to be inserted into the socket of the host connector. The detection pin 102 is connected to a recess on the surface of the output cable housing 103, and the end of the detection pin 102 is flush with the surface of the output cable housing 103. When the output cable connector 1 is connected to the host connector, the output pin 101 is first connected to the socket. After the output pin 101 is connected to the socket at the correct position for a certain distance, the detection pin 102 is then connected to the socket. Compared to four pins being connected to four holes simultaneously, two output pins 101 are inserted and connected to two sockets, making alignment easier and installation more convenient. The output line pin 101 also serves as a guide for the detection pin 102. After the output line pin 101 is aligned and connected to the socket, the detection pin 102 will naturally align with the socket without requiring separate positioning. The detection pin 102 and the socket will not increase the difficulty of connecting the output line pin 101 to the socket.
[0056] In a preferred embodiment, the detection pin 102 is located in the middle of the output line pin 101, the detection socket is located in the middle of the host socket, and the bottom surface of the detection socket is provided with a detection spring. When the output line pin 101 is in good contact with the socket, the end of the detection pin 102 presses against the detection spring to ensure good contact between the detection pin 102 and the detection spring, and to send an accurate feedback signal.
[0057] Multiple detection pins 102 can cooperate with a shared detection spring in the same intermediate detection socket, resulting in a simple structure; alternatively, each detection pin 102 can be equipped with a detection socket, and each detection socket can be provided with a detection spring. This eliminates the influence of the pressure of the detection pin 102 on the detection spring on the deformation of the detection spring, thus eliminating mutual interference between the detection pins 102 and ensuring that each detection pin 102 provides the most accurate detection result, preventing misjudgment.
[0058] Based on the above specific embodiments, the connecting plate 401 is provided with a connecting post 4012 and connecting holes 4011 located on both sides of the connecting post 4012. The output line 2 is welded to the connecting post 4012, and the copper mesh plate 402 is welded to the connecting plate 401 at the connecting holes 4011.
[0059] In one specific embodiment, the connecting plate 401 is provided with a connecting post 4012 for separately connecting the output line 2, and the connecting post 4012 is higher than the surface of the connecting plate 401. Preferably, the height of the connection point of the connecting post 4012 is equal to the center height of the output line 2. When the output line 2 is connected to the connecting post 4012, the bottom surface of the output line 2 contacts the connecting plate 401, the output line 2 is directly connected to the connecting post 4012, and the bottom surface of the output line 2 is supported by the connecting plate 401, so the bottom is not suspended. The connection between the output line 2 and the connecting post 4012 is not subject to torque, and the connection is firm.
[0060] The connecting plate 401 has a separate connecting hole 4011 for connecting the copper mesh plate 402. The copper mesh plate 402 is soldered to the connecting plate 401 at the connecting hole 4011. The output line 2 and the connection between the copper mesh plate 402 and the connecting plate 401 do not interfere with each other. The connecting holes 4011 are located on both sides of the connecting plate 401. The copper mesh plate 402 and the connecting plate 401 are connected at multiple points and in multiple directions. Even if a point connection fails, the copper mesh plate 402 and the connecting plate 401 can still maintain conductivity. This ensures that the connecting plate 401 is flat and prevents the connecting plate 401 from warping.
[0061] Based on the above specific embodiments, there are multiple capacitor electrode plates 4, one of which has a connecting plate 401 connected to the output line, and the connecting plates 401 of the remaining capacitor electrode plates 4 are connected in series.
[0062] In one specific embodiment, when there are two or more capacitor electrode plates 4, each capacitor electrode plate 4 can be equipped with an output line 2. If one output line 2 is damaged, it will not affect the conduction of other capacitor electrode plates 4, making it easy to troubleshoot wiring faults.
[0063] Alternatively, one of the capacitor electrode plates 4 can be connected to the output line via its connecting plate 401, while the connecting plates 401 of the remaining capacitor electrode plates 4 are connected in series. This reduces the number of output lines 2 and simplifies the connection between the output lines 2 and the capacitor electrode plates 4. All capacitor electrode plates 4 can be connected with a single wiring, making operation convenient. Specifically, adjacent capacitor electrode plates 4 are connected by wires. These wires can be external or embedded in the connecting groove within the strap, resulting in a simple and aesthetically pleasing structure.
[0064] Based on the above specific embodiments, the capacitor electrode plate 4 includes a lower protective plate 403 and an upper protective plate 404 that form a protective chamber. The copper mesh plate 402 is fixed on the lower protective plate 403. The outer surface of the lower protective plate 403 is in contact with the treatment site. The connecting plate 401 is located at the corner of the copper mesh plate 402. The output line 2 is fitted with an output line sheath 33 near the connecting plate 401. The output line sheath 33 is connected to the connecting plate 401 and / or the lower protective plate 403.
[0065] In one specific embodiment, the edges of the lower protective plate 403 and the upper protective plate 404 are connected, forming a protective chamber. The copper mesh plate 402 is sewn together with the lower protective plate 403. The copper mesh plate 402 is the treatment area, and the outer surface of the lower protective plate 403 is in contact with the treatment site. The output line sheath 33 is connected to the end of the output line 2. The output line sheath 33 is relatively soft and has insulation properties, separating the output line 2 from the connecting plate 401. The end of the output line 2 does not directly contact the connecting plate 401 and the copper mesh plate 402, preventing the output line solder joint from falling off. The output line sheath 33 has a protective function for the output line 2.
[0066] Based on the above specific embodiments, the connecting post 4012 and the output line 2 are connected in a straight line. The connecting plate 401 and the lower protective plate 403 are provided with several sets of mounting holes 40 on both sides of the output line 2. The two ends of the cable tie 406 pass through two mounting holes 40 and bind the output line sheath 33.
[0067] In one specific embodiment, the output wire sheath 3 and the output wire 2 are tied to the connecting plate 401 and the lower protective plate 403 by cable ties 406, so that the output wire sheath 3 and the output wire 2 are integrated with the connecting plate 401 and the lower protective plate 403, thereby reducing the relative movement between the output wire 2 and the connecting plate 401, that is, reducing the wear of the output wire 2 and preventing the output wire 2 from loosening and falling off.
[0068] Based on the above specific embodiments, the output line sheath 3 is provided with a groove that cooperates with the cable tie 406.
[0069] In one specific embodiment, the output line sheath 3 has a groove at the binding point, and the cable tie 406 is connected to the groove. The groove limits the cable tie to prevent it from slipping off after binding.
[0070] Based on the above specific embodiments, the electrode plate support 5 includes a strap and an outer fabric sleeve 503 connected to the strap. The strap is an elastic self-adhesive strap 502. The end of the outer fabric sleeve 503 is provided with a self-adhesive connecting part 501 that cooperates with the elastic self-adhesive strap 502. The outer fabric sleeve 503 is provided with a connecting sleeve 504 that is fitted onto the strap. The connecting sleeve 504 is movably connected to the strap. The side of the connecting sleeve 504 that contacts the strap is provided with Velcro that is bonded to the strap. The capacitor electrode plate 4 is wrapped inside the outer fabric sleeve 503.
[0071] In one specific embodiment, after the lower protective plate 403 and the upper protective plate 404 are sewn together, the entire assembly is inserted into the inner fabric cover and sewn together, resulting in an aesthetically pleasing and comfortable-to-the-touch capacitor electrode plate 4. The inner fabric cover wraps around the outer fabric cover 503 of the electrode plate support 5, forming an organic whole with the capacitor electrode plate 4. The relative position of the outer fabric cover 503 and the strap can be adjusted. The lead wire is a retractable lead wire, allowing for free adjustment of the position of the outer fabric cover 503 according to different people, body parts, heights, and body types, thus adjusting the capacitor electrode plate 4 to the desired position. Preferably, after the relative position of the outer fabric cover 503 and the strap is adjusted, the Velcro of the outer fabric cover 503 is attached to the strap to fix the outer fabric cover 503 and the strap, preventing the outer fabric cover 503 from shifting. The self-adhesive connection part 501 adheres to the elastic self-adhesive strap 502 to achieve the purpose of wearing.
[0072] In the above embodiments, the capacitive electrode plate 4 can be easily adjusted and attached to the area requiring treatment, making it convenient for patients to use, reducing patient complaints, and improving the overall experience.
[0073] Based on the above specific embodiments, the capacitive electrode device further includes a temperature monitoring mechanism for controlling the temperature of the treatment surface in contact with the treatment area to be lower than a set temperature. The temperature monitoring mechanism may include a temperature sensor and a temperature monitoring unit. The temperature sensor detects the temperature of the treatment surface; the temperature monitoring unit is connected to the temperature sensor and controls the capacitive electrode device to cut off power when the temperature detected by the temperature sensor is higher than the set temperature. By monitoring the temperature of the treatment surface in real time through the temperature monitoring mechanism, burns to the patient due to excessively high treatment surface temperature can be prevented.
[0074] In a preferred embodiment, the lower protective plate 403 is made of felt and has a thickness of 7mm-10mm. The relatively thick lower protective plate 403 provides good insulation, reducing the risk of burns to the patient. The lower protective plate 403 and the upper protective plate 404 are covered by an inner fabric sleeve 405, which is connected to the outer fabric sleeve 503. The felt is elastic, and the inner and outer fabric sleeves 405 and 503 are soft and comfortable when placed on the treatment area.
