Description

Technical Field

[0001] The present invention relates to medical equipment, in particular to a cloud pulse instrument reproduction terminal. Background Art

[0002] Pulse diagnosis, a key method in traditional Chinese medicine (TCM), has a long history and a profound theoretical foundation. Practitioners palpate the patient's wrist pulse to detect various pulse characteristics, such as position, rate, strength, and shape. This allows them to assess the patient's health and the nature, location, and severity of illnesses, providing crucial information for diagnosis and treatment. However, this traditional pulse diagnosis method faces numerous limitations and challenges in modern society.

[0003] With the accelerating pace of life and the expansion of geographical coverage, patients may be unable to travel to hospitals or clinics to receive on-site pulse diagnosis by Traditional Chinese Medicine practitioners due to factors such as distance, time, and physical inconvenience. For example, patients in remote areas may lack local high-quality Traditional Chinese Medicine medical resources and need to travel long distances to obtain professional pulse diagnosis services. Some patients with chronic diseases or mobility difficulties face great difficulties in frequently seeking medical treatment outside the home. In addition, in special circumstances such as global public health events, people's travel is restricted and on-site medical treatment is hindered, making traditional face-to-face pulse diagnosis difficult to implement, seriously affecting the timeliness and convenience of Traditional Chinese Medicine diagnosis and treatment, which may delay the diagnosis and treatment of the disease and pose a potential threat to the patient's health.

[0004] To address these issues, the scientific and technological community has been exploring the possibility of remote pulse diagnosis using modern technology in recent years. Early attempts included having patients describe their pulse sensations or using simple pulse monitoring devices to record pulse data and transmit it to doctors. However, these methods have significant limitations. Self-described pulses are often inaccurate and subjective, failing to accurately reflect the subtle characteristics and changes in the pulse. Conventional pulse monitoring devices can only capture limited information, such as basic pulse frequency, and are unable to comprehensively and accurately capture the rich information inherent in pulses, including complex and critical indicators such as pulse strength, elasticity, vessel thickness, and blood flow. This makes it difficult for doctors to make accurate and reliable Traditional Chinese Medicine diagnoses based on this incomplete data.

[0005] To simulate blood flow and vascular elasticity in the human wrist, existing cloud pulse instrument reproduction terminals often have the following essential features: First, to simulate vascular elasticity, a closed or open liquid circulation chamber and a highly elastic liquid container (such as a hydraulic oil tank) are required to simulate the heart's pumping of blood. This circulatory system inevitably requires a pressurized circulation chamber. Second, to simulate real blood, a liquid with a similar density must be used, and specific electrolytes must be added to maintain viscosity and density. These essential features inevitably lead to the following problems: As the closed liquid circulation chamber continuously expands and contracts, material aging is accompanied by pressure changes. Specifically, to generate the same elastic force at the capillary end, a greater internal pressure must be applied at the container end, resulting in a gradual distortion of the final reproduction effect. The pressure applied by the voice coil motor must be regularly increased to compensate for errors caused by material aging. However, the elasticity of the circulation chamber does not decay linearly, and pressure adjustment to compensate for errors requires the intervention of experienced traditional Chinese medicine practitioners to ensure that the input signal is as consistent as possible with the actual reproduction result. This results in a large amount of repetitive work, wastes manpower and resources, and is inconvenient to use. The hydraulic storage box increases the overall size and weight of the equipment, which is not conducive to miniaturization and portable use.

[0006] Furthermore, the use of an open piping system inevitably requires consideration of the sealing of each pipe joint. Since pipes are typically thin, material degradation due to aging, or fatigue swings driven by diastolic and systolic pressures, can lead to leaks or even breakage from the inner wall or pipe joints, increasing maintenance frequency and overall costs. Furthermore, the indirect transmission of pressure fluctuations through the fluid in the elastic liquid circulation chamber inevitably results in delays, resulting in a suboptimal initial experience. Summary of the Invention

[0007] The purpose of the present invention is to provide a cloud pulse instrument reproduction terminal, which fundamentally solves the above problems and has the advantages of simple structure, accurate reproduction, and easy use.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The cloud pulse instrument reproduction end includes a box assembly, three fingerprint units assembled on the box, and a plurality of voice coil motor units for driving the fingerprint units. The technical key points are: A conductive fiber is fixed to the motor cover of the voice coil motor unit, and the other end of the conductive fiber fits inside the finger mold unit. The voice coil motor unit drives the motor cover to float through the input current. Driven by the motor cover, the conductive fiber expands and contracts with the input current, converting the current fluctuation at the input end of the voice coil motor unit into fluctuations at the corresponding point on the finger mold unit. The box assembly includes a front shell and a main shell that cooperate with each other, and a sheet metal frame fixed in the main shell; The fingerprint unit includes a fingerprint body, an upper cover embedded in the fingerprint body, and a flexible pad covering the upper cover. The bottom of the fingerprint body is provided with an embedding protrusion for the conductive fiber. The fingerprint body is provided with a slot for assembling the upper cover, and a guide column is provided in the slot. The upper cover is provided with a cluster end with an array of through holes, and the array of through holes corresponds to the guide column. The bottom of the sheet metal frame is parallel to the bottom of the main shell, and both sides are symmetrically raised. The voice coil motor unit is symmetrically fixed on the sheet metal frame.

[0009] Furthermore, the voice coil motor unit includes a motor bracket as the main structure and a voice coil motor for driving the conductive fiber to move synchronously; the motor bracket includes a plurality of L-shaped brackets stacked upward with the help of a support frame and with no interference between the vertical extension parts; a catheter positioning column is provided on the top of the L-shaped bracket, and a catheter positioning cap is matched on the catheter positioning column.

[0010] Furthermore, the voice coil motor is fixed on the L-shaped bracket, the motor cover of the voice coil motor is floatingly fitted through the guide shaft and the stroke is constrained by the L-shaped bracket, and a fiber card slot is provided at the rear end of the motor cover which is coaxial with the guide tube positioning column, and a locking card is installed on the fiber card slot.

[0011] Furthermore, the conductive fiber is sleeved in the catheter, one end of which is fixed to the rear end of the motor cover by a locking card, and the other end extends upward along the catheter positioning column. The end of the catheter is limited in the catheter positioning groove of the catheter positioning column and is fastened by the catheter positioning cap, so that the conductive fiber slides relative to the catheter.

[0012] The present invention has the following advantages: Due to its simple structure, compact size, fast response, and zero hysteresis, the voice coil motor unit's output directly drives the floating of various points within the flexible pad via conductive fibers with virtually zero latency. This allows for highly accurate multi-point feedback reproduction without relying on liquid conduction, avoiding the risk of misdiagnosis due to delays at the reproduction end.

[0013] The reproduction end still utilizes a fingerprint unit with multi-point feedback, eliminating the need for a liquid container. This simplifies the structure of the existing reproduction device without compromising reproduction accuracy, resulting in a simpler overall design and completely avoiding the risk of leakage due to material aging and pipe joint seals. This simplified structure reduces points of failure and the probability of overall equipment failure due to component failure, significantly improving equipment stability and reliability. It eliminates the need for frequent inspection and maintenance of the liquid system, reducing maintenance costs and manpower, while also minimizing equipment failure and damage caused by leakage and extending the equipment's service life.

[0014] The control module of the present invention can quickly and accurately convert the pulse signals of the Cun, Guan, and Chi parts into floating currents, and finally convert them into guiding fiber movements through the voice coil motor, accurately reproducing various characteristics of the pulse wave on the flexible pad of the fingerprint unit in a point array manner, meeting the requirements of different users and application scenarios for pulse wave reproduction accuracy, and improving the overall performance and applicability of the pulse diagnosis instrument.

[0015] The motor bracket adopts a modular structure, which accumulates several L-shaped brackets in the height direction, and leads the guide fibers out at the rear end of the motor bracket. The staggered structure at the rear end of the bracket avoids interference between the guide fibers.

[0016] In summary, the cloud pulse instrument reproduction end of the present invention simplifies the structure and avoids the risk of leakage, while improving stability and reliability. It is easy to operate, convenient to transmit data, and more accurate in reproducing pressure signals, providing a more advanced and reliable device for traditional Chinese medicine pulse diagnosis.

[0026] The following combination Figures 1 to 5, the specific contents of the present invention are described in detail through specific embodiments.

[0027] Embodiment 1 Voice Coil Motor Unit 3

[0028] like Figures 2 to 5 As shown, the intelligent pulse voice coil motor includes a motor bracket 34, a first voice coil motor 31, and a second voice coil motor 32 fixed to the motor bracket 34. The motor bracket 34 includes an L-shaped bottom bracket 341 and an inverted L-shaped support frame 343 that cooperate with each other, and an L-shaped top bracket 342 fixed to the support frame 343. The vertical portions of the bottom bracket 341 and the top bracket 342 are respectively located on two non-interfering vertical planes. The bottom bracket 341 is provided with a first motor limiting slot 3413, and the top bracket 342 is provided with a second motor limiting slot 3423.

[0029] The bottom bracket 341 is provided with a hollow first conduit positioning post 3411, to which a first conduit positioning cap 3412 is fixed. The top bracket 342 is provided with a hollow second conduit positioning post 3421, to which a second conduit positioning cap 3422 is fixed.

[0030] The first voice coil motor 31 includes a motor body embedded in a first motor retaining slot 3413, a pair of first guide shafts 313 vertically fixed within a bottom bracket 341, and a first motor cover 311 floating along the first guide shafts 313 and constrained by the bottom bracket 341. The rear end of the first motor cover 311 is provided with a first fiber retaining slot 312 that engages with the first guide tube positioning post 3411. A first locking clip 314 is fixed to the first fiber retaining slot 312. Several bottom mounting clips 3415 are provided at the bottom of the bottom bracket 341.

[0031] The second voice coil motor 32 includes a motor body embedded in a second motor limiting groove 3423, a pair of second guide shafts 323 fixed in the top bracket 342 along the vertical direction, and a second motor cover 321 floatingly arranged along the second guide shafts 323 and constrained by the top bracket 342. The rear end of the second motor cover 321 is provided with a second fiber clamping groove 322 that cooperates with the second guide tube positioning column 3421, and a second locking card 324 is fixed on the second fiber clamping groove 322.

[0032] To detect the movement of the first motor cover 311 or the first fiber slot 312, a Hall effect signal plate (not shown) is installed on the bottom bracket 341 or the top bracket 342. A magnet (not shown) is installed on one side of the Hall effect signal plate between the first motor cover 311 or the second motor cover 321. To facilitate connection of the drive circuit, a motor drive board (not shown) is fixed to the side of the bottom bracket 341 and the top bracket 342.

[0033] This embodiment uses a two-layer L-shaped bracket with a bottom bracket 341 and a top bracket 342 as an example. In actual applications, the configuration can be adjusted based on the weight and size of the voice coil motor, the internal layout of the cabinet assembly 1, and other factors. However, it should be noted that for portability, brackets are typically lightweight. This can cause resonance between the bottom bracket and the voice coil motor, increasing the swing amplitude of the top bracket and reducing the overall structural stability. Therefore, a two- to three-layer bracket is preferred. This specification uses a two-layer bracket as an example to illustrate specific embodiments of the present invention.

[0034] Example 2 Fingerprint Unit 2

[0035] like Figure 1c 、 Figure 1d As shown, this embodiment primarily describes a finger mold unit 2 for use with the voice coil motor unit 3 of Example 1. Specifically, it comprises a finger mold body 21 with a groove 213, an upper cover 23 that fits within the groove 213, and a flexible pad 22 covering the upper cover 23. The bottom of the finger mold body 21 is provided with a hollow, recessed protrusion 212 for conducting fibers. A guide post 211 is located within the groove 213. The hollow structure between the groove 213 and the recessed protrusion 212 is connected via the guide post 211. A central portion of the upper cover 23 features a clustering end 231 with an array of through-holes, the number of which corresponds to the number of fibers guided within the guide post 211. To facilitate installation of the finger mold unit 2, the finger mold body 21 is designed with a symmetrical stepped structure. During installation, after the finger mold unit 2 is assembled, it is inserted from bottom to top into the upper half of the sheet metal frame 14. The screws on both sides of the finger mold body 21 are then tightened to secure it to the sheet metal frame 14.

[0036] During operation, the voice coil motor unit 3 drives its corresponding guide fiber within the plastic conduit. When the motor cover floats upward, the guide fiber protrudes upward beyond the cluster end 231 and presses against the inner wall of the flexible pad 22. When the motor cover floats downward, the guide fiber moves downward, causing the corresponding points on the array of cluster end 231 to dent. This coordinated action of multiple points allows each guide fiber to rise and fall regularly along the guide post 211 over time, achieving pixel-level reproduction of the Cun, Guan, and Chi acupoints.

[0037] This embodiment uses a guide post 211 with ten points as an example. If manufacturing cost is not a concern, the voice coil motor can be further miniaturized, the number of voice coil motors can be increased, and the number of layers of motor brackets 34 can be increased. This can increase the "resolution" of the reproduction without significantly increasing the overall weight of the device.

[0038] like Figure 1 、 Figure 1a 、 Figure 1bAs shown, this embodiment mainly describes a cloud pulse instrument reproduction end using the voice coil motor unit 3 of Example 1, specifically comprising a cabinet assembly 1, three finger print units 2 arranged side by side, and a plurality of voice coil motor units 3 for driving the finger print units 2. The cabinet assembly 1 includes a main housing 12 with an open front end, an L-shaped front housing 11 snap-fitted to the front opening of the main housing 12, and a sheet metal frame 14 fixed within the front housing 11.

[0039] The sheet metal frame 14 is constructed as a frame structure consisting of two parts. The center of the lower frame is fixed to the bottom surface of the main housing 12, with its sides symmetrically raised. The upper frame is N-shaped, with its sides welded or secured to the sides of the lower frame with bolts and nuts. The fingerprint unit 2 is fixed to the center of the upper frame, and several voice coil motor units 3 are symmetrically distributed and fixed to the lower half of the sheet metal frame 14. After the front housing 11 and the main housing 12 are fastened together, the fingerprint frame 112 is snap-fastened to the center of the front housing 11. The back of the main housing 12 is provided with a removable back panel equipped with an exhaust fan outlet. Furthermore, for ease of operation, a power switch 111 is provided on one side of the front housing 11. To facilitate human-computer interaction or remote visual communication, a display screen assembly 13 is hingedly attached to the main housing 12, along with an audio module and a microphone module. For ease of use, a pair of magnets are symmetrically positioned on the front housing 11. The display assembly 13 is magnetically attached to the front housing 11 when snapped together. To facilitate transport, handles (not shown) are also located on either side of the main housing 12. To enhance the aesthetics, a light strip (not shown) is located on the front of the front housing 11.

[0040] During assembly, each voice coil motor unit 3 is symmetrically secured to the lower half of the sheet metal frame 14 using bottom mounting clips 3415 according to a pre-set layout. Because the bottom frame rises symmetrically on both sides, each motor bracket 34, under its own weight, is locked in place by the bottom mounting clips 3415, eliminating the need for bolts. After the voice coil motor units 3 are installed, the power and data cables of the driver boards (not shown) of each voice coil motor unit 3 are electrically connected to a hub (not shown) secured to the inner wall of the front or rear end of the main housing 12 via leads with quick-connect connectors.

[0041] Because there are many replicated points, each corresponding to a voice coil motor, a multi-layered motor bracket 34 is used to facilitate assembly of the voice coil motor array. This embodiment uses a double-layer bracket as an example. The motor bracket 34 includes a bottom bracket 341 fixed to the sheet metal frame 14, a support frame 343 fixed to the bottom bracket 341, and a top bracket 342 fixed to the support frame 343.

[0042] Example 3 Cloud Pulse Instrument Reproduction Terminal

[0043] like Figure 3 、 Figure 4 、 Figure 5 The following describes the installation of the conductive fiber (not labeled) and plastic conduit (not labeled) using the first voice coil motor 31 as an example. The bottom of the first voice coil motor 31 is inserted into the first motor retaining slot 3413 of the bottom bracket 341 and secured with bolts from bottom to top. A pair of first guide shafts 313 are symmetrically fixed to the bottom bracket 341 on either side of the first motor retaining slot 3413. The first motor cover 311 is fixed to the linear moving component (not labeled) with a pair of bolts and guided by the first guide shafts 313, allowing it to float with the moving component. A first fiber retaining slot 312 is provided at the rear end of the first voice coil motor 31. A first locking clip 314 is secured to the first fiber retaining slot 312 with a pair of bolts. A hollow first conduit positioning post 3411 is coaxially mounted on the bottom bracket 341, corresponding to the first fiber retaining slot 312. A first conduit positioning cap 3412 is secured to the first conduit positioning post 3411.

[0044] The bottom end of the conductive fiber (not labeled) is embedded in the first fiber retaining slot 312 and secured by the first locking clip 314, allowing the conductive fiber to float with the first motor cover 311. The bottom end of the plastic conduit (not labeled) is embedded in the first conduit positioning slot 3414 or the second conduit positioning slot 3424 and secured by the first conduit positioning cap 3412. The other end of the conductive fiber passes through the plastic conduit and continues upward. The plastic conduit and the guide fiber simultaneously extend upward to the guide post 211 of one of the fingerprint bodies 21. The conductive fiber within the conduit should have a certain degree of bending resistance to prevent the conductive fiber protruding outside the guide post 211 from bending, which could affect the accuracy of the replication results. It should also have a certain degree of toughness to prevent breakage in the intermediate section between the guide post 211 and the voice coil motor during floating in the first motor cover 311 or the second motor cover 321. Therefore, polyetheretherketone (PEEK), polycarbonate (PC), quartz, or glass fiber are preferred. Furthermore, the outer diameter of the guide fiber is slightly smaller than the inner diameter of the plastic conduit, so as to reduce the resistance of the guide fiber during sliding as much as possible.

[0045] To prevent interference between the guide fibers at the output ends of the two voice coil motors, the bottom bracket 341 and top bracket 342 are designed with a front-to-back offset. To enhance guidance and sliding performance, sufficiently long vertical sections are reserved at the initial guide end (i.e., the first fiber retaining groove 312 and the first guide pin 3411) and the final end (i.e., the guide pin 211). To prevent excessive floating of the first motor cover 311 or the second motor cover 321, both the bottom bracket 341 and the top bracket 342 utilize a gantry structure. This not only facilitates rearward retraction of the voice coil motor, reducing the overall thickness of the motor bracket 34, but also limits the travel of the first motor cover 311 or the second motor cover 321.

[0046] In order to more intuitively illustrate the main structure of the present invention, most of the wires, bolts, nuts, sealing rings and other parts are omitted in the accompanying drawings. It can be understood that under the conception of the present invention, those skilled in the art can connect and fix the corresponding parts in combination with conventional technical means in this field in actual applications, and flexibly adjust and optimize according to actual conditions to implement the technical solution of the present invention.
