Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a fully automatic intelligent acupoint positioning ruler. Background Technology

[0002] "Body-body cun" is a unique unit of measurement for relative human proportions in Traditional Chinese Medicine (TCM) acupuncture. Its core idea is that while everyone's body structure proportions are similar, height, weight, and build vary. Therefore, fixed absolute lengths (such as centimeters or inches) cannot be used to locate acupoints; instead, certain parts of the individual's body should be used as standard measurements. For example, the thumb-body-body cun measurement method uses the lateral width of the patient's thumb joint as "1 cun," and then uses this as the basic dimension for measurement. "Body-body cun acupoint" is not a single acupoint, but rather refers to the method of using body-body cun to find and determine the location of acupoints.

[0003] Currently, in TCM clinical practice, when locating acupoints, doctors typically first use calipers to measure the size of a specific part of the patient's thumb to determine a basic "body-length" measurement. Then, based on this basic size and the relative positional relationships recorded in acupoint charts, they manually calculate the actual size corresponding to the acupoint. Finally, they manually adjust the calipers again to determine the specific location of the acupoint. However, this entirely manual measurement method has significant drawbacks. On the one hand, the entire process is tedious and repetitive, time-consuming, and severely limits diagnostic efficiency. On the other hand, manual calculation introduces human error, which may affect the accuracy and consistency of acupoint location. Therefore, the traditional manual measurement method needs improvement in efficiency, accuracy, and standardization.

[0004] To address these technical issues, we propose a fully automatic intelligent acupoint positioning ruler. Summary of the Invention

[0005] This invention provides a fully automatic intelligent acupoint positioning ruler to solve the problems of cumbersome and complicated manual measurement of acupoints and the easy existence of measurement errors mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic intelligent body-on-body acupoint positioning ruler, comprising the ruler body and an electronic measuring device; The electronic measuring device is slidably mounted on the ruler, and the ruler is equipped with a drive mechanism, which is used to drive the electronic measuring device to move automatically along the ruler. The electronic measuring device is used to measure the thumb and obtain its basic dimensions. Based on the basic dimensions, the electronic measuring device automatically calculates the distance between the acupoints on the same body and moves automatically along the ruler to the corresponding position. The electronic measuring device is also equipped with an identification mechanism, which is used to determine the thumb position and position the electronic measuring device when the electronic measuring device acquires basic dimensions. The electronic measuring device is also equipped with an acupoint indicator. When the electronic measuring device automatically moves to the corresponding position, the acupoint indicator marks the corresponding acupoint. A magnetic clutch assembly is provided between the drive mechanism and the electronic measuring device, and the electronic measuring device is coupled or separated from the drive mechanism through the magnetic clutch assembly.

[0007] Furthermore, the drive mechanism includes a sliding component that is slidably mounted on the ruler body; The magnetic clutch assembly includes an electromagnet and a conductive mechanism, with the electromagnet attached to an electronic measuring device and facing the slider.

[0008] Furthermore, the conductive mechanism includes a conductive sheet, a conductive terminal, and a spring made of ferromagnetic material. The conductive sheet is attached to the electromagnet and faces the conductive terminal, which is movably mounted on the slider by the spring.

[0009] Furthermore, the electromagnet can be energized or de-energized. When the electromagnet is energized, the spring is stretched by magnetic force, and the conductive terminal moves toward the electromagnet and contacts the conductive plate to conduct electricity.

[0010] Furthermore, the sliding member has a guide hole facing the electromagnet, the conductive terminal is slidably disposed in the guide hole, and the spring is attached between the bottom of the guide hole and the conductive terminal.

[0011] Furthermore, the sliding member is provided with a connecting part made of ferromagnetic material, which is offset from the guide hole. When the electromagnet is energized, the electromagnet attracts the connecting part.

[0012] Furthermore, the drive mechanism also includes a lead screw and a motor, with the motor driving the slider to slide along the ruler body via the lead screw.

[0013] Furthermore, the ruler body is equipped with a fixed measuring jaw, and the electronic measuring device is equipped with a movable measuring jaw. The movable measuring jaw and the fixed measuring jaw are arranged facing each other, and the identification is set on the movable measuring jaw and faces the fixed measuring jaw.

[0014] Furthermore, the identification mechanism includes a transmission block, a pressure sensor, and a receiving groove. The receiving groove is located on the side of the movable measuring jaw facing the fixed measuring jaw. The transmission block is movably installed in the receiving groove and extends at least partially out of the receiving groove. The pressure sensor is fixed between the transmission block and the side wall of the receiving groove.

[0015] Furthermore, a distance sensor is embedded on the side of the movable measuring jaw facing the fixed measuring jaw, and the distance sensor is staggered from the identification mechanism.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The device automatically detects and acquires the patient's thumb size using a motorized electronic measuring unit. The recognition mechanism responds instantly upon contact with the thumb, triggering measurement and enabling rapid and accurate acquisition of basic dimensions. This significantly improves the efficiency and accuracy of basic dimension acquisition before acupoint location. Based on the acquired basic dimensions, the electronic measuring unit automatically calculates the target acupoint size according to a preset ratio and automatically moves to the corresponding position, displaying the size visually on the ruler. This process achieves fully automated operation from acquiring basic dimensions to marking acupoint dimensions, effectively avoiding errors that may occur during manual conversion and adjustment, and significantly improving the accuracy and reliability of acupoint location.

[0017] Through the coordinated design of the magnetic clutch component and the conductive mechanism, the switching between electric and manual movement modes can be realized. This allows users to flexibly choose the control method according to the actual operating environment and needs, ensuring both the accuracy and convenience of the electric mode and retaining the adaptability and controllability of the manual adjustment. This expands the practicality and applicability of the invention in different clinical scenarios.

[0018] In summary, this invention transforms the traditional experience-based body measurement method into an automated operation process by combining mechatronics and intelligent recognition. This improves the efficiency and consistency of acupoint location in traditional Chinese medicine while reducing the operational threshold and the risk of human error, thus demonstrating good clinical application value and promising prospects for promotion.

It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] Please see Figures 1 to 12 : The present invention provides a fully automatic intelligent body-based acupoint positioning ruler, including a ruler body 100 and an electronic measuring device 200. The electronic measuring device 200 is slidably disposed on the ruler body 100 and can be moved electrically or manually along the ruler body 100.

[0036] like Figure 1 , Figure 6 , Figure 8 As shown, in this embodiment, the electronic measuring device 200 has a mating groove 205 on the side facing the ruler 100, which mates with the ruler 100. The ruler 100 passes through the mating groove 205, allowing the electronic measuring device 200 to slide back and forth on the ruler 100. The electronic measuring device 200 internally houses a microcontroller and a power module. The power module provides power to the electronic components, and the microcontroller automatically controls the electronic components and receives and processes data. Furthermore, the electronic measuring device 200 is equipped with a display screen and control buttons. The display screen shows the real-time measured dimensions, and the control buttons, including measurement buttons and value input buttons, allow control of the electronic measuring device 200.

[0037] The ruler body 100 of the present invention is provided with a fixed measuring jaw 101, and the electronic measuring device 200 is provided with a movable measuring jaw 201, which is arranged facing the fixed measuring jaw 101. The ruler body 100 is also provided with a driving mechanism for driving the electronic measuring device 200 to move electrically. A magnetic attraction clutch assembly is provided between the driving mechanism and the electronic measuring device 200, which includes an electromagnet 401 and a conductive mechanism. When the electromagnet 401 is energized, the electronic measuring device 200 is attracted to the driving mechanism through the electromagnet 401, and the electronic measuring device 200 is electrically connected to the driving mechanism through the conductive mechanism. The electronic measuring device 200 is provided with an identification mechanism 203, which is disposed on the movable measuring jaw 201 and faces the fixed measuring jaw 101. The identification mechanism 203 is used to determine the position of the object being measured and to coordinate with the electronic measuring device 200 to measure the dimensions.

[0038] like Figure 1 , Figure 4 , Figure 5 , Figures 11 to 12 As shown, in one embodiment of the present invention, the driving mechanism includes a slider 302 slidably mounted on the ruler body 100, wherein the slider 302 is a sliding block. An electromagnet 401 is attached to the electronic measuring device 200 and faces the slider 302. The driving mechanism also includes a lead screw 301 and a motor 303, the motor 303 pushing the slider 302 along the ruler body 100 via the lead screw 301. Specifically, the ruler body 100 has a guide groove 102 facing the electronic measuring device 200 and the mating groove 205. The slider 302 is located within the guide groove 102 and slidably connected to it. The electromagnet 401 extends into the guide groove 102. The lead screw 301 is rotatably mounted within the guide groove 102 and passes through the slider 302 and is threadedly connected to it. The motor 303 is mounted on the outer side of the ruler 100. One end of the lead screw 301 extends through the guide groove 102 and connects to the power output end of the motor 303, enabling the motor 303 to drive the lead screw 301 to rotate. The rotating lead screw 301 pushes the slider 302 to slide within the guide groove 102. Furthermore, when the electronic measuring device 200 is coupled to the drive mechanism via a magnetic clutch assembly, the sliding slider 302 synchronously drives the electronic measuring device 200 to slide on the ruler 100. Additionally, when the electronic measuring device 200 and the drive mechanism are coupled, the motor 303 is electrically connected to the microcontroller integrated within the electronic measuring device 200 via a conductive mechanism, allowing the microcontroller to automatically control the motor 303.

[0039] In this embodiment, the electronic measuring device 200 is also provided with a fine-tuning knob 500, which can control the drive mechanism. Thus, during measurement, the fine-tuning knob 500 can be turned to manually adjust the measurement size.

[0040] In other embodiments (not shown in the figures), the drive mechanism can also employ various linear motion drive schemes to achieve automatic movement of the electronic measuring device 200. For example, a gear and rack transmission mechanism can be used, where a motor 303 drives the gear to rotate, thereby driving the rack connected to the electronic measuring device 200 to achieve linear displacement. Alternatively, a linear motor 303 can be used for direct drive, utilizing its high response and high precision characteristics to achieve smooth and rapid positioning of the device; in addition, precision micro-displacement mechanisms such as piezoelectric ceramic drives can be used, which are particularly suitable for high-precision measurement scenarios.

[0041] All of the above-mentioned electric drive methods are feasible technical solutions of the present invention, and can be flexibly selected according to different requirements such as accuracy, speed, and cost in actual applications, and do not constitute a limitation on the scope of protection of the present invention.

[0042] like Figure 1 , Figure 6 As shown, in one embodiment of the present invention, the identification mechanism 203 includes a transmission block 2031, a pressure sensor 2032, and a receiving groove 2012. The receiving groove 2012 is formed on the side of the movable measuring jaw 201 facing the fixed measuring jaw 101. The transmission block 2031 is movably mounted in the receiving groove 2012 and extends at least partially out of the receiving groove 2012. The pressure sensor 2032 is fixed between the transmission block 2031 and the side wall of the receiving groove 2012. A distance measuring sensor 202 is embedded in the side of the movable measuring jaw 201 facing the fixed measuring jaw 101, and the distance measuring sensor 202 is offset from the identification mechanism 203.

[0043] In this embodiment, both the pressure sensor 2032 and the distance sensor 202 are signal-connected to the microcontroller within the electronic measuring device 200. The distance sensor 202 is a laser distance sensor or an infrared distance sensor, etc., used to detect the distance between the fixed measuring jaw 101 and the movable measuring jaw 201, and converts this distance information into an electrical signal that is transmitted to the microcontroller. After receiving and processing the signal, the microcontroller displays the measurement result in real time on the display screen. The fixed measuring jaw 101 has a measurement reference surface on the side facing the movable measuring jaw 201. When measuring the patient's thumb size, the thumb is stably placed against this measurement reference surface, and the electronic measuring device 200 moves towards the thumb under the drive of the drive mechanism. When the movable measuring jaw 201 contacts the thumb surface, the transmission plate is squeezed by the thumb and transmits the pressure to the pressure sensor 2032. The pressure sensor 2032 detects the pressure signal in real time and sends it to the microcontroller. After receiving a pressure signal that reaches a set threshold, the microcontroller immediately stops the movement of the electronic measuring device 200. At this point, the distance sensor 202 accurately measures the final distance between the fixed measuring claw 101 and the movable measuring claw 201, and transmits this data to the microcontroller. The microcontroller records this distance value and determines it as the basic dimension of "1 inch", providing a calculation benchmark for subsequent acupoint positioning.

[0044] In other embodiments (not shown in the figures), the identification mechanism 203 may also employ a variety of electronic sensing elements to achieve the contact detection function.

[0045] For example, components such as infrared sensors, photosensors, or tactile switches can be used to replace the existing structure. For instance, using an infrared sensor, when the movable claw 201 is not in contact with the thumb, the infrared light emitted by the sensor directly illuminates the air. Due to the strong scattering of infrared light by the air and the long distance, the reflected light signal received by the infrared sensor's receiver is very weak. When the movable claw 201 moves under the drive mechanism and comes into contact with the patient's thumb surface, the distance between them decreases sharply. The thumb skin tissue strongly reflects the infrared light. At this time, the infrared sensor's infrared receiver receives the significantly increased intensity of the reflected infrared light signal and converts it into a sudden change in electrical signal. This electrical signal is transmitted to the microcontroller, thereby completing the thumb identification.

[0046] If a photosensitive sensor is selected, when the movable jaw 201 contacts the thumb, it can sense changes in light intensity caused by ambient light or obstruction, thereby determining whether the movable jaw 201 is fully in contact with the thumb surface and issuing an identification signal accordingly.

[0047] If a tactile switch is used, the mechanical action of the switch can be directly triggered when the movable claw 201 touches the thumb and reaches a certain pressure, generating an electrical signal to cut off the power supply to the motor 303, thereby achieving a fast-response stop control.

[0048] All of the above-mentioned sensor solutions can achieve reliable position or contact state recognition and can work with microcontrollers to control the drive mechanism, thus providing flexible alternatives in application scenarios with different accuracy and cost requirements, further enhancing the adaptability and configurability of the present invention.

[0049] like Figure 2 , Figure 3 , Figure 9 , Figure 11 , Figure 12 As shown, in one embodiment of the present invention, the conductive mechanism includes a conductive sheet 4012, a conductive terminal 402, and a spring 403 made of ferromagnetic material. The conductive sheet 4012 is attached to an electromagnet 401, and the conductive terminal 402 is movably disposed on a sliding member 302 via the spring 403. When the electromagnet 401 is energized, the spring 403 is stretched by magnetic force, and the conductive terminal 402 moves toward the electromagnet 401 and contacts the conductive sheet 4012 for conduction. The sliding member 302 has a guide hole 3022 facing the electromagnet 401. The conductive terminal 402 is slidably disposed in the guide hole 3022, and the spring 403 is attached between the bottom of the guide hole 3022 and the conductive terminal 402. The conductive sheet 4012 faces the conductive terminal 402. The sliding member 302 is provided with a connecting part 3021 made of ferromagnetic material. The connecting part 3021 is staggered from the guide hole 3022. When the electromagnet 401 is energized, the electromagnet 401 and the connecting part 3021 are attracted together.

[0050] In this embodiment, the conductive terminal 402 is connected to the motor 303 via a wire, and there are two conductive terminals 402, namely a positive terminal and a negative terminal. The conductive terminal 402 is made of a non-ferromagnetic conductive material, such as copper or aluminum. By making the conductive terminal 402 a non-ferromagnetic conductive material, when the electromagnet 401 is energized and generates a magnetic force, the conductive terminal 402 will not be attracted to the electromagnet 401.

[0051] The electromagnet 401 has two slides 4011 corresponding to the conductive terminals 402. Conductive plates 4012 are embedded inside the slides 4011 and connected to the microcontroller and power module inside the electronic measuring device 200 via wires. When the electromagnet 401 is energized, the generated magnetic force attracts the spring 403, causing the spring 403 to extend. Under the action of the extended spring 403, the conductive terminals 402 extend outward along the guide hole 3022 and into the corresponding slides 4011, ultimately making electrical contact with the conductive plates 4012. Figure 12As shown. At this time, the motor 303 forms a complete electrical connection with the microcontroller and power module through this conductive path, enabling the microcontroller to automatically control the motor 303. The slide rail 4011 has guiding and limiting functions, ensuring that it maintains stable and tight contact with the conductive sheet 4012. At the same time, when the energized electromagnet 401 passes over the conductive terminal 402 and engages with the connecting part 3021, the slide rail 4011 allows the conductive terminal 402 to slide inside it, thereby avoiding interference with the movement of the electromagnet 401.

[0052] In this embodiment, as Figure 1 , Figure 6 , Figure 8 As shown, the electronic measuring device 200 also includes a clutch switch 600, which is electrically connected to the electromagnet 401 and used to control the energization and de-energization of the electromagnet 401. When the clutch switch 600 is closed, the electromagnet 401 is de-energized and loses its magnetic force. At this time, the electromagnet 401 separates from the connecting part 3021, the spring 403 retracts and resets, and drives the conductive terminal 402 out of the slide rail 4011 and separate from the conductive plate 4012. This disconnects the electrical connection between the motor 303 and the microcontroller and power module inside the electronic measuring device 200. In this state, the electronic measuring device 200 enters manual operation mode, and the user can directly push the electronic measuring device 200 along the ruler 100 by hand to perform manual measurement.

[0053] To restore the electric control mode, the electronic measuring device 200 must first be moved to the position between the fixed measuring jaw 101 and the sliding member 302. Then, the electromagnet 401 is energized by the clutch switch 600. The electronic measuring device 200 is then pushed towards the sliding member 302. When the electromagnet 401 moves above the connecting part 3021, it automatically engages with the connecting part 3021 under magnetic force. Simultaneously, the conductive terminal 402 extends from the guide hole 3022 under the guidance of the mechanical structure, re-establishing electrical contact with the conductive sheet 4012 in the slide rail 4011. This allows the motor 303 to reconnect to the microcontroller and power module, restoring the electric control mode.

[0054] In this embodiment (not shown in the accompanying drawings), to enhance the adhesion between the electromagnet 401 and the connecting part 3021, silicone material is used to connect the connecting part 3021 and the sliding member 302. Utilizing the elastic properties of silicone, when the electromagnet 401 and the connecting part 3021 are attracted, the silicone can undergo slight deformation, allowing the connecting part 3021 to undergo a slight displacement towards the electromagnet 401. This effectively eliminates assembly gaps or air gaps between the two, significantly improving the stability and tightness of the adhesion.

[0055] like Figures 6 to 8As shown, in one embodiment of the present invention, the movable claw 201 is further provided with an acupoint indicator 204 for indicating the location of acupoints.

[0056] Specifically, a recessed portion 2011 is provided at the tip of the movable measuring claw 201, and the recessed portion 2011 is composed of two mutually perpendicular planes. An acupoint indicator 204 is embedded in each plane. In this embodiment, the acupoint indicator 204 is a laser emitter. The laser emitter emits a visible light beam. When using this positioning ruler to locate acupoints, the beam is projected onto the surface of the human skin, forming a clear light spot, thus visually identifying the location of the acupoint. By arranging the two laser emitters perpendicularly to each other, beams parallel to and perpendicular to the movable measuring claw 201 can be emitted respectively. This method can adapt to the measurement needs of different parts of the human body, helping to improve the convenience of operation and the accuracy of measurement, enhancing the practicality and adaptability of the device. In other embodiments, the acupoint indicator 204 can also be an LED indicator, an optical projection indicator, etc.

[0057] In summary, when using this invention, the patient's thumb is first placed between the fixed measuring jaw 101 and the movable measuring jaw 201, ensuring that the thumb is in close contact with the measuring reference surface on the fixed measuring jaw 101. Then, the measurement button is pressed, and the electronic measuring device 200 automatically moves towards the thumb. When the movable measuring jaw 201 contacts the thumb, the electronic measuring device 200 automatically measures and records the distance, setting it as the basic dimension of "1 inch".

[0058] After determining the basic dimensions, the positioning ruler is moved to the body part to be measured, aligning the fixed measuring jaw 101 with the measurement starting point. The distance to the target acupoint is input via the numerical input button, such as "3 inches," and the electronic measuring device 200 automatically moves to the corresponding position based on the pre-calibrated "1 inch" reference. Subsequently, the acupoint indicator 204 emits a beam of light onto the skin surface, clearly marking the acupoint location, thus quickly and accurately locating the acupoint.
