[0002] A pulse acquisition instrument is a medical device that can collect human pulse information. It is often used in clinical diagnosis of traditional Chinese medicine, providing doctors with objective and quantitative pulse data to assist them in making more accurate judgments on the condition, greatly improving the accuracy and reliability of diagnosis.

[0003] When using a pulse acquisition instrument, the patient needs to place their wrist naturally and comfortably below the instrument. The operator then needs to carefully control the instrument and adjust it so that the sensor on the instrument accurately contacts the patient's pulse. During this process, it is necessary to ensure that the contact force is moderate, neither too light to cause unclear acquisition signals nor too heavy to cause discomfort to the patient, so as to achieve effective and accurate acquisition of pulse information and provide a reliable data basis for subsequent analysis and diagnosis. However, traditional pulse acquisition instruments are often manually operated and adjusted by medical staff. The instrument's sensor is placed at the patient's pulse position based solely on experience and visual observation, leaving no effective reference for the pressure between the sensor and the skin. This can result in excessive or insufficient pressure between the sensor and the skin, easily causing changes to the original pulse. It may also be impossible to obtain a clear and accurate pulse signal, making the collected pulse data unstable and reducing the accuracy of the diagnosis. Utility Model Content

The pressure sensor can measure the contact pressure between the instrument and the skin. When the acquisition portion of the instrument contacts the patient's skin during the pulse acquisition process, the pressure sensor feedback data is analyzed and processed according to a pre-set pressure range. The pressure is automatically adjusted to the optimal pressure value most suitable for the patient by controlling the adjustment motor of the adjustment component to adjust the screw rod.

On the other hand, the elasticity of the rubber block can play a buffering role, further stabilizing the pressure transmission and reducing the interference of pressure fluctuations on the pulse signal. At the same time, the acquisition sensor is set as a U-shaped sleeve on the rubber block, which can more accurately capture the pulse information transmitted through the rubber block, thereby improving the accuracy of the acquisition. Compared with traditional instruments, this instrument can more realistically reflect the patient's pulse characteristics, provide doctors with a more reliable basis for diagnosis, and reduce the risk of misdiagnosis due to unstable acquisition.

[0018] 3. The reasonable connection and layout of the connecting frame and components such as the pressure sensor, acquisition sensor and rubber block in the assembly ensure the reliability of pulse acquisition. The connecting block on the top of the first mounting seat is clamped in the connecting groove of the connecting frame, ensuring the stable installation of the pressure sensor and not prone to loosening or displacement. The rubber block is sleeved on the pressing block, which not only protects the patient's skin from direct pressure, but also provides good anti-slip and cushioning effects, preventing the acquisition effect from being affected by slight movements of the patient's wrist during the acquisition process. At the same time, button holes are opened on the instrument casing corresponding to the control buttons, which not only facilitates operation but also protects the control buttons to prevent accidental touch and dust intrusion. These structural settings and protective measures jointly improve the reliability and durability of the instrument, reduce the failure rate of the equipment, and can maintain stable performance in long-term medical use, providing reliable support for clinical diagnosis.

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0028] Example:

[0029] like Figures 1 to 2As shown, the present invention provides a self-calibrating pressure pulse acquisition instrument, comprising an instrument housing 11, which serves as the basic framework of the entire device and provides stable protection and support for the internal components; a housing cover 12 that covers the instrument housing 11, and the two together form a relatively closed installation cavity, creating a stable working environment for the processing module 21 and the control module 22, thereby protecting them from external interference and enabling them to accurately perform their respective functions. A placement plate 13 is provided on one side of the instrument housing 11. During the acquisition process, the patient places their wrist on the placement plate 13 so that the device can accurately contact the patient's pulse. An adjustment component and a acquisition component are located above the placement plate 13. The adjustment component is connected to the instrument housing 11 and its other end is connected to the acquisition component. The acquisition component is responsible for adjusting the position and state of the acquisition component during pulse acquisition. The acquisition component includes a connecting frame 31 for connecting the entire acquisition component to the adjustment component. A first mounting seat 32 and a second mounting seat 33 are provided below the connecting frame 31. A pressure sensor 34 sandwiched between the first mounting seat 32 and the second mounting seat 33 is used to sense the contact pressure with the patient's skin. When the patient places his wrist on the placement plate 13, the regulating assembly can, according to preset program and parameters, move the acquisition assembly to a suitable position so that the pressure sensor 34 can contact the patient's pulse place accurately. At this moment, the pressure sensor 34 starts working, and it can monitor the pressure change between the acquisition assembly and the skin in real time, and transmits these data to the processing module 21. The processing module 21 analyzes and processes these data, and then controls the regulating assembly through the control module 22, further adjusts the position and the pressure of the acquisition assembly, to ensure that the pulse information collected is accurate and stable.

[0030] The adjustment assembly includes an adjustment seat 41, which is clamped between two sets of protrusions 14 symmetrically distributed on the instrument housing 11. It is not only stable and reliable, but also detachably connected to the instrument housing 11 by screws, which provides convenience for the maintenance and replacement of the equipment. When the adjustment seat 41 needs to be maintained or replaced, the operator can easily unscrew the screws and remove the adjustment seat 41 from between the protrusions 14 without causing excessive interference to other parts of the instrument. The mounting plates 43 at both ends of the adjustment seat 41 provide support for the adjustment screw 42. The bearings provided on the mounting plates 43 enable the adjustment screw 42 to rotate freely therein, reducing frictional resistance and ensuring smooth adjustment.

[0031] The adjustment assembly also includes an adjustment motor 44 located on top of a mounting plate 43 above the adjustment seat 41. The motor's shaft end is connected to an adjustment screw 42, providing power for the rotation of the adjustment screw 42. Precise control of the adjustment motor 44 enables the adjustment screw 42 to rotate, thereby driving the adjustment slider connected to it to adjust its displacement.

[0032] The adjustment slider includes a sliding block 45 and a stop block 46. An adjustment through-hole 47 on the sliding block 45 allows the adjustment screw 42 to pass through it. When the adjustment screw 42 rotates, the sliding block 45 slides along the axial direction of the adjustment screw 42 through the action of the thread. One end of the connecting frame 31 is connected to the sliding block 45, so that the displacement of the sliding block 45 can drive the acquisition component to make corresponding position adjustments to ensure that the pressure sensor 34 can accurately contact the patient's pulse and maintain appropriate pressure. The stop block 46 is located between the adjustment seat 41 and the sliding block 45 and is detachably connected to the sliding block 45. The stop block 48 on the adjustment seat 41 is fixed in the stop block 46 to form a concave-convex structure, which can prevent the sliding block 45 from excessive displacement or deviation from the track during sliding, thereby ensuring the accuracy and stability of the adjustment.

[0033] The first mounting base 32 is located above the second mounting base 33. The square connecting block 35 at the top of the first mounting base 32 cooperates with the connecting groove 36 on the connecting frame 31. The connecting block 35 is clamped in the connecting groove 36 to form a stable connection. A pressing block 37 is provided at the bottom of the second mounting base 33. The arc surface at the bottom of the pressing block 37 matches the arc surface of the rubber block 38 below. The curvature of the rubber block 38 is consistent with the arc surface curvature of the pressing block 37, so that the rubber block 38 can be sleeved on the pressing block 37. The arc-shaped setting can better adapt to the curve of the human wrist. When the instrument contacts the patient's wrist, the rubber block 38 can fully fit the wrist surface, so that the pressure is evenly distributed in the pulse area, avoiding the influence of excessive or too little local pressure on the pulse acquisition. At the same time, the rubber block 38 has good elasticity and can play a buffering role. During the acquisition process, even if the patient's wrist moves or shakes slightly, the rubber block 38 can also buffer these external forces through its own elastic deformation, further stabilizing the pressure transmission and reducing the interference of pressure fluctuations on the pulse signal. One end of the acquisition sensor 39 passes through the connecting frame 31 and the slot 17 in the instrument housing 11, connecting to the processing module 21. The other end is configured as a U-shaped sleeve on the rubber block 38, which can more accurately capture the pulse information transmitted through the rubber block 38. The connecting frame 31 is equipped with multiple groups of lasers that can emit laser beams to assist in positioning, ensuring that the patient's wrist is accurately placed under the acquisition assembly.

[0034] Control module 22 is positioned at processing module 21 top, and perpendicular to processing module 21, this layout rationally utilizes instrument inner space.Control module 22 is provided with multiple groups of control buttons, instrument housing 11 corresponding control buttons offer keyhole 15, and control button is arranged in the keyhole 15, and protrudes in instrument housing 11 one sides, has made things convenient for the operator that instrument is controlled and operated.The protruding control button is easy to touch and identification, and the operator can, under the situation that does not affect the normal operation of instrument and pulse condition collection, easily carry out the setting and the adjustment of various parameters to instrument by these buttons.

[0035] The processing module 21 is provided with multiple sets of wiring heads, which are important interfaces for data transmission inside the instrument and connection with external devices. The outer shell cover 12 has multiple sets of wiring ports 16 corresponding to the wiring heads. When it is necessary to connect external devices such as displays, printers or other data storage devices, fast and stable data transmission can be achieved through these wiring ports 16 and wiring heads, ensuring the effective output and further processing of pulse collection data, providing a convenient data interaction channel for medical diagnosis and research.

[0036] The specific usage and function of this embodiment are as follows:

[0037] During use, guide the patient to place their arm in a relaxed and natural position on the placement plate 13 on one side of the instrument, with their wrist straight and palm facing upward. As needed, connect external devices to the connection port 16 on the instrument housing 11 via the corresponding connecting cable. Ensure that the connecting cable plug is connected to the connection port 16 without any looseness. Turn on the instrument's power supply. The indicator light on the instrument's control module 22 should light up, indicating that the instrument is powered on. Press the corresponding control button on the control module 22 through the key hole 15 on the instrument housing 11 to enter the instrument's parameter setting interface. Set appropriate parameters such as the pressure range and acquisition frequency based on the patient's specific condition and diagnostic needs. For example, for patients with weaker constitutions, the pressure range can be appropriately lowered; for situations requiring more detailed pulse analysis, the acquisition frequency can be increased. Start the instrument's automatic calibration program. The instrument automatically controls the adjustment component to place the pressure sensor 34 in the acquisition component in the initial position between the placement plate 13 and perform pressure reference calibration. During the calibration process, the instrument will display the calibration progress and results through the control module 22.

[0038] After the instrument completes calibration, confirm that the patient's wrist position is correct and stable again.Press the collection button on the control module 22, and the adjustment motor 44 of the instrument starts working.The adjustment motor 44 drives the adjustment screw 42 to rotate, and then the collection component is slowly lowered by adjusting the slider, until the rubber block 38 in the collection component contacts the pulse place of the patient's wrist gently.During the contact process, the pressure sensor 34 monitors the pressure change between the collection component and the skin in real time, and transmits the data to the processing module 21.The processing module 21 controls the adjustment component by the control module 22 according to the preset pressure range and algorithm, and automatically adjusts the position and pressure of the collection component so that the pressure sensor 34 remains at the optimal pressure value to ensure that stable and accurate pulse information is collected.In the collection process, the collection sensor 39 continues to capture the pulse information transmitted through the rubber block 38, and transmits the data to the processing module 21 for processing and storage through the through slot 17.

[0039] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
