Description

Technical Field

[0001] This utility model belongs to the field of pulse diagnosis instrument technology, and in particular relates to a pulse diagnosis instrument detection probe spacing adjustment device. Background Technology

[0002] Pulse diagnosis, an important diagnostic tool in Traditional Chinese Medicine (TCM), allows for assessment of a patient's health by palpating the radial artery. With technological advancements, pulse diagnosis equipment has become increasingly intelligent and digital, providing more objective and accurate evidence for TCM clinical diagnosis. However, existing pulse diagnosis devices still have some shortcomings in probe design, particularly the fixed probe spacing, which to some extent limits their widespread application and diagnostic effectiveness.

[0003] II. Shortcomings of existing technologies

[0004] Fixed probe design: Most pulse diagnosis devices use a fixed probe design, with the spacing between probes predetermined at the factory and unable to be adjusted according to individual patient differences. Human arm size varies from person to person, and pulse location may also differ among patients. A fixed probe design makes it difficult to adapt to all patients' arm sizes and pulse locations, leading to inaccurate positioning.

[0005] Impact of inaccurate positioning: When the probe cannot be accurately aligned with the pulse location, the acquired pulse signal will be inaccurate. This inaccuracy may stem from a positional shift between the probe and the pulse, leading to weakened signal strength, waveform distortion, and other problems. Inaccurate pulse signals can affect the diagnostic accuracy of pulse diagnosis equipment, and may even lead to misdiagnosis or missed diagnosis, posing unnecessary risks to patients.

[0006] Limited user experience: The fixed probe design limits the applicability of pulse diagnosis devices, especially for patients with unusual arm sizes or abnormal pulse positions, where it may be unusable or provide poor diagnostic results. This limitation reduces the versatility and convenience of pulse diagnosis devices, hindering their widespread clinical application.

[0007] In view of the inadequacy of the fixed probe spacing in existing pulse diagnosis equipment, there is an urgent need for a pulse diagnosis instrument probe spacing adjustment device that can adjust the probe spacing according to individual patient differences. Utility Model Content

[0008] To address the problems existing in the prior art, this utility model provides a device for adjusting the distance between the detection probes of a pulse diagnostic instrument.

More preferably, the spacing adjustment component includes a T-shaped groove at the lower end of the pulse pressure heads on both sides, perpendicular to the pulse probe in the middle position, a T-shaped slider installed in the T-shaped groove, and a pulse sensor installed on the T-shaped slider; an adjustment seat is installed on the outside of the pulse probe, and an adjustment screw is installed on the adjustment seat along the direction of the T-shaped groove, the threaded section of the adjustment screw engaging with the threaded section of the T-shaped slider.

[0010] More preferably, the adjusting screw has a smooth rod section near the adjusting nut, and the smooth rod section is fitted into the slot of the adjusting seat.

[0011] The advantages and technical effects of this invention are as follows: The spacing adjustment component of this invention exhibits excellent technical performance within a limited space. Its compact design allows the T-shaped groove and T-shaped slider to fit together tightly, achieving precise movement of the pulse sensor within a limited space.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] Please see Figure 1 andFigure 2 A pulse diagnosis probe spacing adjustment device is disclosed, characterized in that: the pulse diagnosis instrument is equipped with three pulse diagnosis probes 11 arranged in a straight line. This design allows the pulse diagnosis unit to simultaneously monitor multiple pulse points on the user's wrist, improving the comprehensiveness and accuracy of pulse diagnosis. Each pulse diagnosis probe 11 includes an electric cylinder 12, the lower end of which is connected to a pulse diagnosis pressure head 13. This structure allows the pulse diagnosis pressure head to move precisely up and down as needed to adapt to different wrist thicknesses, ensuring close contact between the pulse diagnosis sensor and the user's wrist. A pulse diagnosis sensor 14, electrically connected to an external display and control terminal, is installed at the lower end of the pulse diagnosis pressure head. The pulse diagnosis sensor uses a high-precision pressure sensor to collect the user's pulse information; its precise position adjustment and stable contact pressure ensure the accuracy and reliability of the pulse information. Overall, this technical solution improves the automation and intelligence level of pulse diagnosis, providing a more objective and accurate diagnostic basis for traditional Chinese medicine pulse diagnosis.

[0017] In the above technical solution, the pulse sensor of the pulse pressure head located in the middle adopts a fixed structure. This design provides a stable reference point and ensures accurate acquisition of pulse information at the middle position during pulse diagnosis. Meanwhile, the pulse sensors on both sides can move longitudinally relative to the pulse sensor in the middle position via the spacing adjustment component 20. This innovative design greatly improves the adaptability of the pulse diagnosis unit.

[0018] Because the pulse position distribution varies among different users, a fixed spacing between pulse sensors may not meet the needs of all users. By allowing the pulse sensors on both sides to move longitudinally, the spacing between the sensors can be adjusted according to the user's actual pulse position distribution, ensuring that each pulse sensor can accurately align with the corresponding pulse point, thereby improving the accuracy and comprehensiveness of pulse diagnosis.

[0019] Furthermore, this adjustable spacing design allows the pulse diagnosis unit to be suitable for users with different body types and wrist sizes, enhancing the device's versatility and practicality. Users can easily adjust the position of the pulse sensor according to their own pulse characteristics for a more personalized pulse diagnosis experience.

[0020] The spacing adjustment assembly 20 includes T-shaped grooves 21 at the lower ends of the pulse probes on both sides, perpendicular to the middle pulse probe. This design provides a stable track for the longitudinal movement of the pulse sensor, ensuring smoothness and accuracy during movement. A T-shaped slider 22 is installed within the T-shaped groove, and a pulse sensor 14 is mounted on the T-shaped slider, allowing the sensor to adjust its position as the slider moves. An adjustment seat 23 is installed on the outer side of the pulse probe, further enhancing the flexibility and convenience of spacing adjustment. An adjustment screw 24 is installed on the adjustment seat along the T-shaped groove, and the threaded section of the adjustment screw engages with the threaded section of the T-shaped slider, enabling precise control of the sensor position. When the sensor spacing needs to be adjusted, simply rotating the adjustment screw drives the T-shaped slider to move within the T-shaped groove, thereby changing the position of the pulse sensor. The adjusting screw is provided with a smooth section 240 near the adjusting nut. The smooth section is fitted into the slot 230 of the adjusting seat. This design not only enhances the stability of the adjusting screw, but also prevents it from shifting or shaking and axial movement during rotation, ensuring the accuracy and reliability of the spacing adjustment.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
