Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine physiotherapy equipment technology, specifically a sensor-detection type scraping board. Background Technology

[0002] Gua sha, a traditional Chinese medicine external therapy, has the effects of unblocking meridians, promoting blood circulation, removing blood stasis, and regulating qi and blood. Its operating principle involves repeatedly scraping specific areas of the body surface with a gua sha board, causing local congestion or bruising, thereby achieving therapeutic and health-preserving purposes. Currently, gua sha mainly relies on the practitioner holding a gua sha board (such as a copper, wooden, or horn board), but this method still has certain limitations in practical application. The angle at which the gua sha board is held has a significant impact on the therapeutic effect. Studies have shown that when the gua sha board is at approximately a 45° angle to the skin surface, it can apply the most appropriate pressure penetration while conforming to the meridian pathways, thus achieving the best gua sha effect. However, current gua sha operations rely entirely on the practitioner's subjective experience, making it difficult to precisely maintain this angle during prolonged scraping. Furthermore, if the angle deviation is too large, it may not only affect the therapeutic effect but also cause patient discomfort or skin damage due to uneven force application. However, practitioners often find it difficult to detect and adjust the angle deviation in real time during the operation. The frequency of gua sha (i.e., the number of scraping strokes per unit time) is another key factor affecting the treatment effect. An appropriate gua sha frequency can optimize the stimulation intensity and improve treatment efficiency. However, in current technology, doctors can only control the frequency of gua sha based on experience or by manually counting. This method not only has a large margin of error, but also increases the difficulty and labor intensity of the doctor's operation, especially during long-term treatment, it is difficult to ensure the stability and consistency of the frequency.

[0003] The application of existing gua sha boards relies heavily on the personal experience of physicians, lacking precise control over angle and frequency. This not only affects the effectiveness of gua sha therapy but also limits its standardization and widespread adoption. Therefore, optimizing and improving gua sha boards to address these shortcomings has become an urgent problem to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology mentioned above by providing a sensor-activated gua sha board. By adding a handle body with a sensor, the angle between the gua sha board and the skin can be detected in real time during gua sha operation, and a prompt will be issued when the angle deviation is large. At the same time, it can detect and display the gua sha frequency, which is beneficial for doctors to accurately control the entire gua sha treatment process.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A sensor-detection gua sha board includes a gua sha board and a handle body. The handle body includes a body shell and a sensor connecting rod. One end of the sensor connecting rod is movably embedded in the body shell, and the other end extends outward from the end of the body shell. The gua sha board is connected to the outer end of the sensor connecting rod. The body shell is provided with a frequency sensing mechanism and an angle sensing mechanism. The frequency sensing mechanism includes a first sensor for sensing the gua sha action of the gua sha board and a counter for storing and displaying the gua sha frequency. The angle sensing mechanism includes a second sensor for measuring the gua sha angle of the gua sha board and an indicator mechanism for displaying or indicating the current gua sha angle.

[0006] Preferably, the first sensor is a pressure sensor, and the inner end of the sensing connecting rod is in contact with the sensitive element of the pressure sensor.

[0007] Preferably, the sensing connecting rod is slidably connected to the housing, and the relative sliding direction between the sensing connecting rod and the housing is consistent with the length direction of the sensing connecting rod; the housing is provided with a limiting structure inside to limit the sliding stroke of the sensing connecting rod.

[0008] Preferably, the limiting structure includes a limiting groove provided on the inner side of the housing, a protruding slider provided on the side of the sensing connecting rod, the protruding slider being embedded in the limiting groove, and the length of the limiting groove being greater than that of the protruding slider to form a space for the protruding slider to slide with a small stroke, and a spring being provided between at least one end of the protruding slider and the end of the limiting groove.

[0009] Preferably, the second sensor is a tilt sensor with a calibrable reference surface, at least one side wall of the handle body is a measuring reference surface, the reference surface of the tilt sensor is arranged parallel to the measuring reference surface, and the scraping board is arranged parallel to the measuring reference surface.

[0010] Preferably, the indicating mechanism includes a first display screen for displaying the angle measured by the current tilt sensor and an indicator light for indicating whether the scraping angle is appropriate.

[0011] Preferably, the counter includes a second display screen for displaying the frequency of gua sha; the outer wall of the body housing near the end of the sensing connecting rod is provided with an annular light strip, which displays an indicative light when the pressure measured by the pressure sensor exceeds a threshold.

[0012] Preferably, the scraping board includes a scraping structure and a connecting part. The scraping board is designed in various models, and the scraping structure of different models has different sizes and shapes. The outer end of the sensing connecting rod is provided with a fixing structure, and the connecting part is detachably connected to the fixing structure.

[0013] Preferably, the connecting part includes an inner clamping plate and a limiting insertion rod; the fixing structure includes two outer clamping plates, a limiting insertion hole and a set bolt, a clamping groove is formed between the two outer clamping plates, the limiting insertion hole is located in the middle of the clamping groove, and the limiting insertion rod is inserted into the limiting insertion hole at the same time as the inner clamping plate is inserted into the clamping groove; the inner clamping plate is provided with a through hole for the set bolt to pass through, and the two outer clamping plates are locked by the set bolt to clamp and fix the scraping board.

[0014] Compared with existing technologies, the sensor-based gua sha board using the above-mentioned technical solution has the following beneficial effects: The handpiece is equipped with a tilt sensor. During gua sha treatment, the tilt sensor detects the angle between the gua sha board and the skin surface, and can monitor changes in angle in real time. The measured angle is displayed on the screen on the handpiece for the operator to observe. An indicator light will emit a warning signal when the detected angle is too large or too small (e.g., exceeding the range of 45°±5°), reminding the operator to adjust the angle. The tilt sensor can be calibrated to a reference plane. Since the skin may have different tilt levels in various postures or on different areas, calibration can be performed before gua sha, providing greater flexibility.

[0015] The pressure sensor in the handle receives a pressure signal with each scraping motion, which is stored and calculated by a counter. The current scraping frequency (e.g., 30 times / minute, 180 times in total) can be displayed on the screen, allowing the operator to intuitively and accurately know the current frequency for subsequent adjustments. This solves the problems of large deviations and high workload associated with traditional frequency control based on experience and manual counting. In the preferred design, a ring-shaped light strip is added to the handle, connected to the pressure sensor. When excessive scraping pressure is detected (exceeding a set threshold), the ring-shaped light strip emits a warning light, such as a red light or a flashing light, to remind the operator to reduce the scraping pressure.

[0016] Third, the gua sha board and the handle body are detachably connected. Since there are many types of gua sha boards, you can choose the appropriate gua sha board to connect to the handle body as needed, which has better universal applicability. Attached Figure Description

[0023] To further illustrate the technical means and effects of this utility model in order to achieve its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figures 1 to 5 The sensor-activated gua sha tool shown includes a gua sha tool 1 and a handle body 2. The handle body 2 includes a body housing 20 and a sensor connecting rod 21. One end of the sensor connecting rod 21 is movably embedded in the body housing 20, and the other end of the sensor connecting rod 21 extends outward from the end of the body housing 20. The gua sha tool 1 is detachably connected to the outer end of the sensor connecting rod 21. The body housing 20 is provided with a frequency sensing mechanism and an angle sensing mechanism.

[0025] The frequency sensing mechanism includes a pressure sensor 3 and a counter. The pressure sensor 3 is fixedly built into the housing 20. The inner end of the sensing connecting rod 21 contacts and connects to the sensitive element 30 of the pressure sensor 3. When performing scraping, the scraping board 1 and the sensing connecting rod 21 transmit pressure to the pressure sensor 3. The pressure sensor 3 senses the pressure signal to determine that it is a scraping action. The counter includes a second display screen 4, which is located on the surface of the housing 20. A programmable controller is installed inside the housing 20. Both the pressure sensor 3 and the counter are connected to the programmable controller circuit. The counter stores and calculates the received pressure signal (scraping action signal) and displays the scraping frequency information (such as "30 times / minute, 180 times in total") on the second display screen 4. The operator can intuitively and accurately know the current scraping frequency for subsequent adjustment.

[0026] The sensing connecting rod 21 is slidably connected to the housing 20, and the relative sliding direction between the sensing connecting rod 21 and the housing 20 is consistent with the length direction of the sensing connecting rod 21. The housing 20 has an internal limiting structure for restricting the sliding stroke of the sensing connecting rod 21. The limiting structure includes a limiting groove 200 located inside the housing 20, and a protruding slider 210 on the side of the sensing connecting rod 21. The protruding slider 210 is embedded in the limiting groove 200, and the length of the limiting groove 200 is slightly larger than that of the protruding slider 210, allowing the protruding slider 210 to slide with a small stroke within the limiting groove 200. A spring 22 is provided between one end of the protruding slider 210 and the end of the limiting groove 200. Under the elastic force of the spring 22, the inner end of the sensing connecting rod 21 just contacts the sensitive element 30 of the pressure sensor 3, but does not apply sufficient pressure to generate a scraping action signal. During the scraping motion, the inner end of the sensing connecting rod 21 is pressed against the sensitive element 30 of the pressure sensor 3, generating sufficient pressure to produce a scraping motion signal. The outer wall of the device housing 20 near the end of the sensing connecting rod 21 is equipped with a ring-shaped light strip 8. The ring-shaped light strip 8 is electrically connected to the pressure sensor 3. When the pressure sensor 3 detects excessive scraping pressure (exceeding a set threshold), the ring-shaped light strip 8 can emit a warning light, such as illuminating a red light or flashing, to remind the operator to reduce the scraping pressure.

[0027] The angle sensing mechanism includes a tilt sensor 5 and an indicating mechanism. The selected tilt sensor 5 can be calibrated using a reference surface 50. One side wall of the housing 20 is a measuring base surface 201. The reference surface 50 of the tilt sensor 5 is parallel to the measuring base surface 201, and the scraping board 1 is parallel to the measuring base surface 201. During scraping, the measuring base surface 201 of the housing 20 is first placed on the skin of the target scraping area. Then, the tilt sensor 5 is operated to calibrate the reference surface 50. After calibration, the handle 2 can be lifted to perform the scraping operation. The indicating mechanism includes a first display screen 6 and an indicator light 7. The first display screen 6 is located on the surface of the housing 20 and is arranged side by side with the second display screen 4. The indicator light 7 is located on the outer surface of the housing 20 near the sensing connecting rod 21. The tilt sensor 5, the first display screen 6, and the indicator light 7 are all connected to the programmable controller circuit. The first display screen 6 is used to display the angle measured by the tilt sensor 5; the indicator light 7 is used to indicate whether the scraping angle is appropriate: when the tilt sensor 5 detects that the angle is too large or too small (such as exceeding the range of 45°±5°), it will issue an indicator signal, such as lighting up a red light or flashing, to remind the operator to adjust the angle.

[0028] The scraping board 1 includes a scraping structure part 10 and a connecting part 11. The scraping board 1 is designed in various models, with different models having different sizes and shapes of the scraping structure part 10. The outer end of the sensing connecting rod 21 is provided with a fixing structure 23, and the connecting part 11 is detachably connected to the fixing structure 23. The connecting part 11 includes an inner clamping plate 110 and a limiting insertion rod 111; the fixing structure 23 includes two outer clamping plates 230, a limiting insertion hole 231, and a set bolt 232. A clamping groove is formed between the two outer clamping plates 230, and the limiting insertion hole 231 is located in the middle of the clamping groove. The inner clamping plate 110 is inserted into the clamping groove, and the limiting insertion rod 111 is inserted into the limiting insertion hole 231 simultaneously. The inner clamping plate 110 has a through hole for the set bolt 232 to pass through. The two outer clamping plates 230 are locked by the set bolt 232 to clamp and fix the scraping board 1. A suitable scraping board 1 can be selected for connection and use as needed.
