Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an arm diagnostic instrument and its usage method. Background Technology

[0002] Chi-fu diagnosis is one of the important diagnostic methods in traditional Chinese medicine. Its core is that doctors touch and press the skin and muscles on the inner side of the patient's forearm (from the elbow crease to the wrist crease) with their hands to perceive changes in temperature, texture, elasticity, etc., and combine this with the patient's verbal feedback and systemic symptoms to make a judgment on the condition. Traditional skin diagnosis relies entirely on the clinical experience of TCM doctors, using methods such as finger pressure and touch to perceive relevant information. However, this method has many limitations, including: strong subjectivity—different TCM doctors have varying finger sensitivity, pressure levels, and judgment standards, leading to poor consistency in diagnostic results and making it difficult to establish a standardized diagnostic process; lack of quantification—doctors' judgments of skin temperature, muscle texture, and pressure feedback are mostly qualitative descriptions, such as "high temperature" or "hard texture," failing to accurately record the pressure strength, depth, and patient response, lacking precise quantitative data support, which is not conducive to accurate assessment of the condition and subsequent follow-up on treatment efficacy; low efficiency—manual operation requires point-by-point pressure perception, making it difficult to conduct a high-density, comprehensive screening of the forearm in a short time, resulting in poor adaptability to batch physical examinations or primary healthcare scenarios; and high experience dependence—the diagnostic accuracy of skin diagnosis is highly dependent on the doctor's years of experience and clinical accumulation, making it difficult for novice doctors to quickly grasp the essence of this diagnostic method.

[0003] Therefore, there is an urgent need for an intelligent device that can simulate manual pressure and quantitatively collect key information for skin diagnosis. Summary of the Invention

[0004] The main objective of this invention is to propose an arm diagnostic instrument and its usage method, aiming to improve the problem that traditional rudimentary skin diagnostic methods rely heavily on the doctor's clinical experience and are difficult to accurately record relevant data on pressure.

[0005] To achieve the above objectives, the present invention provides an arm diagnostic instrument comprising:

[0006] The mounting base has an arm rest area. The pressing mechanism includes a pressing head that is movable in at least the vertical direction within the arm placement area for pressing the arm. A data acquisition device, disposed on the pressing head, is used to acquire information on the pressing force and temperature of the pressing point; and, The control device is electrically connected to the pressing mechanism and the data acquisition device.

[0007] In one embodiment, the pressing head is movable in both vertical and horizontal directions; The pressing mechanism further includes a linear motion structure and a drive motor. The linear motion structure includes a first linear motion mechanism that moves in the up-down direction and a first slider. The first slider is disposed on the first linear motion mechanism. The lower end of the first slider is provided with the pressing head and a laser emitter. The laser emitter can project a laser point downward to display the projection position of the pressing head on the arm. The drive motor is used to drive the first linear motion mechanism to move. The control device is electrically connected to the drive motor.

[0008] In one embodiment, the arm diagnostic device further includes a visual recognition device, which is disposed toward the arm placement area to obtain position information of the laser point on the arm; The control device is also electrically connected to the visual recognition device.

[0009] In one embodiment, the arm diagnostic device further includes a touch screen electrically connected to the control device and the data acquisition device, allowing the operator to manually input operating commands and display information collected by the data acquisition device.

[0010] In one embodiment, the mounting base is provided with an arm fixing seat, and the arm fixing seat is provided with a groove extending in the front-back direction. The shape of the groove is adapted to fit the human arm, and the groove is located in the arm placement area.

[0011] In one embodiment, the arm diagnostic instrument further includes a voice acquisition device.

[0012] In one embodiment, the pressing head is made of a flexible material, the data acquisition device includes a pressure sensor disposed inside the pressing head, and the pressing force F of the pressing head is in the range of 0.5≤F≤5N.

[0013] In one embodiment, the data acquisition device includes a temperature sensor disposed on the lower end face of the pressing head.

[0014] The present invention also proposes a method for using an arm diagnostic device, for operating the arm diagnostic device as described in any of the preceding claims, wherein the arm diagnostic device further includes a linear motion structure, a drive motor, a laser emitter, a visual recognition device, and a touch screen, the linear motion structure includes a first linear motion mechanism and a first slider, and the method for using the arm diagnostic device includes the following steps: S01: After the visual recognition device acquires an image of the patient's arm, multiple pressing positions are set according to the image acquired by the visual recognition device; S02: Determine the activity trajectory based on the initial position of the pressing head and multiple pressing positions, and control the pressing head to move according to the activity trajectory. Whenever the pressing head reaches a pressing position, control the pressing head to press down for a certain period of time and then lift it to reset. At the same time, acquire the pressing force and temperature information of the pressing position, and display the pressing force and temperature information of the pressing point on the touch screen.

[0015] The technical solution of this invention uses a pressure head to simulate a doctor's finger. Because the pressure head can move up and down, it can press on specific locations on the patient's arm within the arm placement area to perform a rudimentary skin examination. During the pressing process, the data acquisition device can collect information on the pressure applied by the pressure head and the temperature of the pressure point, allowing the doctor to accurately assess the patient's condition based on this precise information. This improves upon the problem of traditional rudimentary skin examinations, which heavily rely on the doctor's clinical experience and struggle to accurately record relevant pressure data.

[0023] Chi-fu diagnosis is one of the important diagnostic methods in traditional Chinese medicine. Its core is that doctors touch and press the skin and muscles on the inner side of the patient's forearm (from the elbow crease to the wrist crease) with their hands to perceive changes in temperature, texture, elasticity, etc., and combine this with the patient's verbal feedback and systemic symptoms to make a judgment on the condition. Traditional skin diagnosis relies entirely on the clinical experience of TCM doctors, using methods such as finger pressure and touch to perceive relevant information. However, this method has many limitations, including: strong subjectivity—different TCM doctors have varying finger sensitivity, pressure levels, and judgment standards, leading to poor consistency in diagnostic results and making it difficult to establish a standardized diagnostic process; lack of quantification—doctors' judgments of skin temperature, muscle texture, and pressure feedback are mostly qualitative descriptions, such as "high temperature" or "hard texture," failing to accurately record the pressure strength, depth, and patient response, lacking precise quantitative data support, which is not conducive to accurate assessment of the condition and subsequent follow-up on treatment efficacy; low efficiency—manual operation requires point-by-point pressure perception, making it difficult to conduct a high-density, comprehensive screening of the forearm in a short time, resulting in poor adaptability to batch physical examinations or primary healthcare scenarios; and high experience dependence—the diagnostic accuracy of skin diagnosis is highly dependent on the doctor's years of experience and clinical accumulation, making it difficult for novice doctors to quickly grasp the essence of this diagnostic method.

[0024] This invention proposes an arm diagnostic instrument 100, which aims to improve the problem that traditional ulnar skin diagnosis relies heavily on the doctor's clinical experience and is difficult to accurately record relevant data on pressure.

[0025] Please see Figure 1 In one embodiment of the present invention, the arm diagnostic device 100 includes a mounting base 1, a pressing mechanism 2, a data acquisition device 3, and a control device; wherein, the mounting base 1 is provided with an arm placement area 61; the pressing mechanism 2 includes a pressing head 21 that is movable at least in the vertical direction within the arm placement area 61 for pressing the arm; the data acquisition device 3 is disposed on the pressing head 21 for collecting the pressing force and temperature information of the pressing point; the control device is electrically connected to the pressing mechanism 2 and the data acquisition device 3.

[0026] The technical solution of this invention uses the pressing head 21 to simulate a doctor's finger. Because the pressing head 21 can move up and down, it can press specific locations on the patient's arm placed within the arm placement area 61 to perform a rudimentary skin examination. During the pressing process, the data acquisition device 3 can collect the pressure intensity of the pressing head 21 and the temperature information of the pressing point, allowing the doctor to accurately assess the patient's condition based on this precise information. This improves upon the problem of traditional rudimentary skin examinations, which heavily rely on the doctor's clinical experience and struggle to accurately record relevant pressure data.

[0027] In actual diagnostic procedures, multiple points on the patient's arm usually need to be pressed. Therefore, to meet this requirement, in this embodiment of the invention, the pressing head 21 is movable in both vertical and horizontal directions. The pressing mechanism 2 also includes a linear motion structure and a drive motor. The linear motion structure includes a first linear motion mechanism 22 and a first slider 23 that move vertically. The first slider 23 is mounted on the first linear motion mechanism 22. The lower end of the first slider 23 is provided with the pressing head 21 and a laser emitter. The laser emitter can project a laser point downwards to display the projection position of the pressing head 21 on the arm. The drive motor is used to drive the first linear motion mechanism 22 to move. The control device is electrically connected to the drive motor.

[0028] In other words, by configuring the pressing head 21 to be movable in the horizontal direction, the pressing position of the pressing head 21 can be adjusted. After adjusting the pressing head 21 to the required pressing position, the pressing head 21 can be controlled to move downwards to press. Furthermore, since the movement of the pressing head 21 is controlled by the linear motion structure, the descent height of the pressing head 21 can be controlled by controlling the movement of the first linear motion mechanism 22, thereby controlling the pressing depth and force. In addition, when adjusting the pressing head 21 in the horizontal direction, to facilitate viewing the projection position of the pressing head 21 on the arm, the present invention also provides a laser emitter at the lower end of the first slider 23. The laser point projected onto the arm by the laser emitter determines the pressing position of the pressing head 21, improving the pressing accuracy. Furthermore, the present invention does not limit the specific form of the first linear motion mechanism 22. For example, in an embodiment of the present invention, the first linear motion mechanism 22 includes a lead screw.

[0029] It should be noted that the present invention does not limit the horizontal movement of the pressing head 21. For example, in the embodiments of the present invention, the pressing head 21 is moved horizontally by the cooperation of multiple linear motion structures and motors. Specifically, the mounting base 1 is provided with a second linear motion mechanism 24 extending in the front-back direction and a second slider 25 sleeved on the second linear motion mechanism 24. The second slider 25 extends upward to form a support frame 26. The support frame 26 is provided with a third linear motion mechanism 27 extending in the left-right direction and a third slider 28 sleeved on the third linear motion mechanism 27. The third slider 28 is used to fix the first linear motion mechanism 22. The second linear motion mechanism 24 and the third linear motion mechanism 27 are both driven by motors, and the motors are electrically connected to the control device. In this embodiment, the horizontal movement of the pressing head 21 is achieved through the cooperation of multiple linear motion structures and a motor. Furthermore, the displacement accuracy of the linear motion structures can be improved to enhance the precision of the pressing head 21. For example, in another embodiment, both the second linear motion mechanism 24 and the third linear motion mechanism 27 are lead screws, and the pitch of the lead screws can be reduced to improve the displacement accuracy. In other embodiments of the invention, two linear guide rail structures can also be used to achieve the horizontal movement of the pressing head 21.

[0030] It should be noted that during the downward movement of the pressing head 21, it is necessary to ensure that the positions of the second slider 25 and the third slider 28 do not move. Therefore, a fixing structure can be provided on the second slider 25 and the third slider 28 to fix the positions of the second slider 25 and the third slider 28 during the downward movement of the pressing head 21. As for the specific fixing structure, the present invention will not elaborate on it. Those skilled in the art can make adaptive adjustments according to the actual situation.

[0031] In one embodiment of the present invention, the arm diagnostic device 100 further includes a visual recognition device 4, which is disposed facing the arm placement area 61 to obtain the position information of the laser point on the arm; the control device is also electrically connected to the visual recognition device 4. That is, by determining the position information of the laser point on the arm through the visual recognition device 4, the control device can pre-set the position to be pressed, and then determine whether the laser point is located at the required pressing position based on the visual recognition device 4, thereby determining whether to control the downward pressing of the pressing head 21, thus achieving automated operation of the arm diagnostic device 100. It should be noted that the present invention does not limit the specific form of the visual recognition device 4; for example, it can be implemented by using a camera to capture real-time images of the arm placement area 61.

[0032] In other embodiments of the present invention, the arm diagnostic device 100 further includes an auxiliary lighting device 8, which includes, but is not limited to, a light lamp. The light lamp is fixed on the mounting base 1 and aligned with the arm placement area 61 to improve the brightness of the image captured by the visual recognition device 4, thereby avoiding the situation where the image captured by the visual recognition device 4 is too dark in a low-light environment.

[0033] Furthermore, in an embodiment of the present invention, the arm diagnostic device 100 also includes a touch screen 5, which is electrically connected to the control device, the data acquisition device 3, and the visual recognition device 4, allowing the operator to manually input operation commands and display information collected by the data acquisition device 3 and the visual recognition device 4. In other words, the touch screen 5 displays images captured by the visual recognition device 4, facilitating the doctor's assessment of the pressure point 21. Simultaneously, the doctor can manually operate the pressure point 21 on the touch screen 5 and display the information collected by the data acquisition device 3 on the data acquisition device 3.

[0034] In an embodiment of the present invention, an arm fixation seat 6 is provided on the mounting base 1. The arm fixation seat 6 has a groove extending in the front-to-back direction. The shape of the groove is adapted to fit the human arm, and the groove is located in the arm placement area 61. That is to say, by providing the arm fixation seat 6, the patient can stably place their arm in the groove, preventing the pressure deviation of the pressing head 21 due to improper fixation of the patient's arm during the ulnar skin examination of the arm diagnostic instrument 100, which would further lead to inaccurate data acquisition.

[0035] Furthermore, to facilitate the placement of the patient's arm within the arm placement area 61 in the forward and backward direction, in this embodiment of the invention, the arm fixing seat 6 is provided with a limiting baffle (not shown) at one end in the forward and backward direction. The limiting baffle extends in the vertical direction for the patient's hand to abut against, ensuring that the patient's arm is within the arm placement area 61. In other words, when the patient extends their arm, simply placing their hand against the limiting baffle ensures that the patient's arm is within the arm placement area 61, preventing excessive forward and backward extension of the arm or insufficient extension that would cause the arm to be positioned outside the normal operating range of the pressing head 21.

[0036] During the arm examination, the patient's pain feedback is equally important when the pressure head 21 presses on the patient's arm. To collect patient feedback information, in this embodiment of the invention, the arm examination device 100 also includes a voice acquisition device 7. With the voice acquisition device 7, when the pressure head 21 moves downwards to press on the patient's arm, the patient can verbally indicate whether there is pain or soreness. The voice acquisition device 7 can then collect this information and integrate it with the pressure and temperature information collected at the pressure point, facilitating the doctor's review and analysis.

[0037] To make the texture of the pressure head 21 closer to the feel of real finger pressure, in this embodiment of the invention, the pressure head 21 is made of a flexible material. The data acquisition device 3 includes a pressure sensor 31 disposed inside the pressure head 21. The pressure intensity F of the pressure head 21 is in the range of 0.5 ≤ F ≤ 5 N. That is, by making the pressure head 21 a flexible material, it is closer to the feel of real finger pressure and reduces patient discomfort. At the same time, by controlling the pressure intensity of the pressure head 21, injury to the patient's arm is prevented. In addition, the measurement accuracy of the pressure sensor 31 is ±0.01 N, ensuring measurement accuracy.

[0038] In an embodiment of the present invention, the data acquisition device 3 includes a temperature sensor 32, which is disposed on the lower end face of the pressing head 21. That is, when the pressing head 21 presses on the patient's arm, the temperature of the patient at the pressing point can be measured by the temperature sensor 32, which helps the doctor to judge the condition. Specifically, the temperature sensor 32 has a measurement range of 20°C to 45°C and a measurement accuracy of ±0.1°C.

[0039] In addition, the control device provided in this application includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the method of using the arm diagnostic device 100 in the following embodiments.

An input / output (I / O) interface 1006 is also connected to the bus. Typically, the following systems can be connected to the I / O interface 1006: input devices 1007 including, for example, a touchpad, keyboard, mouse, image sensor, microphone, accelerometer, gyroscope, etc.; output devices 1008 including, for example, a liquid crystal display (LCD), speaker, vibrator, etc.; storage devices 1003 including, for example, magnetic tape, hard disk, etc.; and communication devices 1009. Communication device 1009 allows the control device to communicate wirelessly or wiredly with other devices to exchange data. Although the figure shows a control device with various systems, it should be understood that it is not required to implement or possess all the systems shown. More or fewer systems may be implemented alternatively.

[0042] Specifically, according to the embodiments disclosed in this application, the processes described above with reference to the flowcharts can be implemented as computer software programs.

When the computer program is executed by processing device 1001, it performs the functions defined in the methods of the embodiments disclosed in this application.

[0043] It should be understood that the various parts disclosed in this application can be implemented using hardware, software, firmware, or a combination thereof. In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0044] Please see Figure 2 The present invention also proposes a method for using the arm diagnostic instrument 100 to achieve automated control of the arm diagnostic instrument 100.

[0045] The arm diagnostic instrument 100 also includes a linear motion structure, a drive motor, a laser emitter, a visual recognition device 4, and a touch screen 5. The linear motion structure includes a first linear motion mechanism 22 and a first slider 23. The method of using the arm diagnostic instrument 100 includes the following steps: S01: After the visual recognition device 4 acquires an image of the patient's arm, multiple pressing positions are set according to the image acquired by the visual recognition device 4; It should be noted that the present invention does not limit the specific locations of the multiple pressing positions mentioned in step S01. Specifically, the control program of the arm diagnostic instrument 100 provided by the present invention has multiple preset schemes, and the multiple pressing positions in each preset scheme are not exactly the same. When using the arm diagnostic instrument 100 provided by the present invention, different pressing positions can be set by selecting different preset schemes. In addition, in addition to setting the pressing positions using the above-mentioned preset schemes, the arm diagnostic instrument 100 provided by this application can also allow doctors to manually set each pressing position on the touch screen 5, so as to deal with different symptoms of different patients or to collect additional information, so that doctors can make better judgments on the patient's condition.

[0046] S02: Determine the activity trajectory based on the initial position of the pressing head 21 and multiple pressing positions, and control the pressing head 21 to move according to the activity trajectory. Whenever the pressing head 21 reaches a pressing position, control the pressing head 21 to press down for a certain period of time and then lift it to reset. At the same time, acquire the pressing force and temperature information of the pressing position, and display the pressing force and temperature information of the pressing point on the touch screen 5.

[0047] In this step, the position of the laser point emitted by the laser emitter on the patient's arm can be determined based on the image captured by the visual recognition device 4, and the initial position of the pressing head 21 can be further determined. Then, the movement trajectory is determined according to the multiple pressing positions set in step S01, so that the pressing head 21 can automatically pass through multiple pressing positions in sequence. Whenever the pressing head 21 reaches a pressing position, the pressing head 21 is controlled to stop its horizontal movement and is controlled to press down for a certain period of time before lifting and resetting. During the pressing process, the data acquisition device 3 can acquire the pressing force and pressing temperature of the pressing head 21 and display them on the touch screen 5 until the pressing head 21 passes through all the pressing positions along the movement trajectory.

[0048] It should be noted that in other embodiments of the present invention with a voice acquisition device 7, when the pressing head 21 presses on the patient's arm during step S02, the patient can describe the pain or soreness caused by the pressing in words, which will be collected by the voice acquisition device 7. The pain or soreness information, the pressure, and the temperature will be recorded together. If the patient has other information that needs to be supplemented, the doctor can also record the relevant information through the touch screen 5. As for how to manually input the information and record it on the touch screen 5, the present invention does not limit it. For example, it can be achieved by connecting an external keyboard or mouse.

[0049] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
