Description

Technical Field

[0001] This invention relates to the field of pulse diagnosis instrument technology, and specifically to a safe pressure mechanism for a pulse diagnosis instrument. Background Technology

[0002] As Wang Shuhe stated in his *Pulse Classic*, "It is easy to understand in the mind, but difficult to discern under the fingers." Traditional Chinese medicine pulse diagnosis has long relied on subjective personal perception and experiential sensory transmission, lacking clear quantitative and qualitative standards. This hinders its widespread use and research in modern medicine, and even causes considerable confusion and daunting challenges for those studying Chinese medicine. Therefore, industry professionals and academic institutions are actively developing scientific pulse diagnosis instruments, considering the objective and standardized study of traditional Chinese medicine pulse diagnosis an important task.

[0003] One type of existing pulse diagnosis device collects data by pressing the pulse sensor down to the pulse point. For example, a pulse diagnosis device with patent number CN114287894A uses a transmission component to press the sensing unit down to the pulse point to collect data. However, the technical solution of this patent does not have any safety measures, such as excessive pressing height or force due to transmission component failure, or the sensing unit failing to lift up after pressing.

[0025] The present invention will now be described in detail with reference to the accompanying drawings: A safe pressing mechanism for a pulse diagnostic instrument according to the present invention includes a tabletop 1, a support frame, and casters. The tabletop 1 is supported by the support frame, and casters are provided at the four corners of the bottom of the support frame. A tabletop cover is provided on the tabletop 1.

A pressing mechanism is mounted on the electric actuator mounting bracket 19, and a pulse sensor 14 is mounted on the pressing mechanism. A photoelectric sensor 5 is provided at one end of the fixed plate 4, and a reflector 6 is provided at the other end of the fixed plate 4. The reflector is installed on the inner wall of the tabletop cover. A light-blocking plate 22 is provided on the electric actuator mounting bracket 19. The total mass of the electric actuator mounting bracket 19, the light-blocking plate 22, the pressing mechanism, and the pulse sensor 14 is 600g. A hand fixing device is provided at the other end of the tabletop 1.

[0026] The support frame 2 is equipped with a first slide rail, and a first slider is slidably mounted on the first slide rail. The first slider is connected to the fixed plate 4. The support frame 2 is equipped with a first servo electric actuator 3, and the fixed plate 4 is equipped with a connecting plate. The piston rod of the first servo electric actuator 3 is connected to the connecting plate.

[0027] The frame 9 is equipped with second slide rails on both sides, and second sliders are slidably mounted on the second slide rails. The second sliders are connected to the second mounting plate 11. The frame 9 is provided with positive and negative lead screws 15, and positive and negative nuts are installed on the positive and negative lead screws 15. The positive and negative nuts are respectively installed on the second mounting plates 11 on both sides of the first mounting plate 10.

[0028] A motor mounting bracket is provided on one side of the frame 9, and a servo motor 16 is mounted on the motor mounting bracket. The output shaft of the servo motor 16 is connected to the positive and negative lead screws 15 through a coupling.

[0029] The electric actuator mounting bracket 19 is connected to a slide rod 20, and a stop is provided at the bottom end of the slide rod 20. The first mounting plate 10 and the second mounting plate 11 are provided with through holes that cooperate with the slide rod 20. A linear bearing 21 is installed at the through hole, and the slide rod 20 is slidably installed in the linear bearing 21. The slide rod 20 is provided with a keyway, and a key is provided in the through hole. The total mass of the electric actuator mounting bracket 19, the slide rod 20, the light blocking plate 22, and the pressing mechanism is 600g. In fact, the installation of each component requires various connecting parts such as screws, and the mass of the pressing mechanism and the connecting parts on the electric actuator mounting bracket should also be included. That is, the total mass of the electric actuator mounting bracket 19, the slide rod 20, the light blocking plate 22, the pressing mechanism, and the connecting parts is 600g.

[0030] The pressing mechanism includes a second servo electric actuator 12, a pressure sensor 17, a connecting plate 18, and a connecting rod 13. The second servo electric actuator 12 is mounted on an electric actuator mounting bracket 19. The pressure sensor 17 is connected to the piston rod of the second servo electric actuator 12.

[0032] A control cabinet is installed below the platform, and a controller is installed inside the control cabinet. When performing pulse diagnosis, the wrist is first placed in the designated position, and the piston rod of the first servo electric actuator 3 is retracted, so that the pulse sensor 14 is 5-10mm above the wrist. The piston rod of the second servo electric actuator 12 is extended, so that the pulse sensor 14 is pressed against the pulse on the wrist. The pressure sensor 17 can collect the pressure signal in real time. When the pressure sensor 17 detects that the pressure value reaches 5N, the second servo electric actuator 12 is stopped. When the piston rod of the second servo electric actuator 12 continues to extend due to system failure or failure of the second servo electric actuator 12, since the total mass of the electric actuator mounting bracket 19, slide rod 20, light shield 22 and pressing mechanism is 600g, when the pressure of the pulse sensor 14 reaches 5.88N, the slide rod 20 can slide upward along the linear bearing 21, thereby ensuring that the downward pressure does not exceed 5.88N and avoiding excessive downward pressure that could harm the patient.

[0033] When the pressing mechanism slides upward, the light-blocking plate 22 will block the light emitted by the photoelectric sensor 5. When the photoelectric sensor 5 does not receive the returned light, it can feed the information back to the controller, and then control the piston rod of the first servo electric push rod 3 to extend, thereby lifting the pulse sensor 14.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
