Description

Technical Field

[0001] The invention belongs to the technical field of pulse acquisition, and more specifically, particularly relates to a pulse acquisition instrument with self-calibration pressure. Background Art

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

[0003] When using the pulse acquisition instrument, the patient needs to place his wrist naturally and comfortably under the instrument. Then, the operator needs to carefully control the instrument and adjust it so that the sensor on the instrument can accurately contact the patient's pulse. In 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 on the patient's pulse position based only on experience and naked eye observation, so that there is no effective reference for the pressure between the sensor and the skin, resulting in excessive or too little pressure between the sensor and the skin, which can easily cause changes in the original pulse, and may also fail to obtain clear and accurate pulse signals, making the collected pulse data unstable, thereby reducing the accuracy of diagnosis.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The acquisition component is provided with a first mounting seat and a second mounting seat under the connecting frame, and the pressure sensor is clamped between the two. The pressure sensor can measure the pressure value of the contact between the instrument and the skin, so that in the pulse acquisition process, when the acquisition part of the instrument contacts the patient's skin, the data fed back by the pressure sensor will be analyzed and processed according to the pre-set pressure range, and the pressure will be automatically adjusted to the best pressure value most suitable for the patient by controlling the adjustment screw rod by the adjustment motor in the adjustment component.

[0017] 2. A pressure sensor is sandwiched between the first mounting seat and the second mounting seat in the assembly, and a pressing block with an arc surface is provided at the bottom of the second mounting seat, and an arc-shaped rubber block is matched below, which can better adapt to the curve of the human wrist and make the pressure evenly distributed in the pulse area. On the other hand, the elasticity of the rubber block can play a buffering role, further stabilize the pressure transmission, and reduce the interference of the pulse signal due to pressure fluctuations. 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, and improve the accuracy of the acquisition. Compared with traditional instruments, this instrument can more truly reflect the pulse characteristics of the patient, provide doctors with a more reliable basis for diagnosis, and reduce the risk of misdiagnosis caused by unstable acquisition.

[0018] 3. The reasonable connection and layout of the connecting frame and the pressure sensor, collection sensor, rubber block and other components in the assembly ensure the reliability of pulse collection. The connecting block on the top of the first mounting seat is stuck in the connecting groove of the connecting frame, ensuring the stable installation of the pressure sensor, which is not easy to loosen or move. The rubber block is sleeved on the pressing block, which can not only protect the patient's skin from direct pressure, but also provide good anti-slip and buffering effects to prevent the slight movement of the patient's wrist during the collection process from affecting the collection effect. At the same time, button holes are opened on the instrument casing corresponding to the control buttons, which not only facilitates the operation but also protects the control buttons to prevent accidental touch and dust from entering. These structural settings and protective measures jointly improve the reliability and durability of the instrument, reduce the equipment failure rate, and can maintain stable performance in long-term medical use, providing reliable support for clinical diagnosis.

[0027] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the scope of protection of the present invention.

[0028] Example:

[0029] like Figure 1 to Figure 2As shown, the present invention provides a pulse acquisition instrument with self-calibration pressure, including an instrument housing 11, the instrument housing 11 is used as the basic frame of the whole device, and provides stable protection and support for the internal components; the housing cover 12 is covered on the instrument housing 11, and the two together form a relatively closed installation cavity, which creates a stable working environment for the processing module 21 and the control module 22, so that they are free from external interference and can accurately operate their respective functions. The placement board 13 on one side of the instrument housing 11, during the collection process, the patient places his wrist on the placement board 13, so that the device can accurately contact the patient's pulse. The adjustment component and the acquisition component above the placement board 13, the adjustment component is connected to the instrument housing 11, and the other end is connected to the acquisition component, which is responsible for adjusting the position and state of the acquisition component when collecting pulse. The acquisition component includes a connecting frame 31, which is used to connect the entire acquisition component with the adjusting component, and a first mounting seat 32 and a second mounting seat 33 are arranged below the connecting frame 31, and 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 adjusting assembly can move the collection assembly to a suitable position according to preset programs and parameters, so that the pressure sensor 34 can accurately contact with the patient's pulse. At this moment, the pressure sensor 34 starts to work, and it can monitor the pressure change between the collection assembly and the skin in real time, and transmits these data to the processing module 21. The processing module 21 can analyze and process these data, and then controls the adjusting assembly through the control module 22, and further adjusts the position and pressure of the collection 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 groups 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 through 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 take the adjustment seat 41 out from between the protrusions 14 without causing too much 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, and the bearings provided on the mounting plates 43 enable the adjustment screw 42 to rotate freely therein, reducing friction resistance and ensuring smooth adjustment.

[0031] The adjustment assembly also includes an adjustment motor 44 located on the top of the mounting plate 43 above the adjustment seat 41, and its shaft end is connected to the adjustment screw 42 to provide power for the rotation of the adjustment screw 42. The precise control of the adjustment motor 44 can realize the rotation of the adjustment screw 42, thereby driving the adjustment slider connected thereto to adjust the displacement.

[0032] The adjusting slider includes a sliding block 45 and a limiting block 46. The adjusting through hole 47 on the sliding block 45 allows the adjusting screw 42 to penetrate therein. When the adjusting screw 42 rotates, the sliding block 45 will slide along the axial direction of the adjusting 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 limiting block 46 is located between the adjusting seat 41 and the sliding block 45, and is detachably connected to the sliding block 45. The limiting protrusion 48 on the adjusting seat 41 is clamped in the limiting block 46 to form a concave-convex structure, which can prevent the sliding block 45 from excessive displacement or deviation from the track during the sliding process, thereby ensuring the accuracy and stability of the adjustment.

[0033] The first mounting seat 32 is located above the second mounting seat 33, and the square connecting block 35 on the top of the first mounting seat 32 cooperates with the connecting groove 36 on the connecting frame 31, and the connecting block 35 is clamped in the connecting groove 36 to form a stable connection mode. A pressing block 37 is arranged at the bottom of the second mounting seat 33, and the arc surface at the bottom of the pressing block 37 matches the arc-shaped rubber block 38 below. The curvature of the rubber block 38 is consistent with the curvature of the arc surface 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 small local pressure on the pulse collection. At the same time, the rubber block 38 has good elasticity and can play a buffering role. During the collection process, even if the patient's wrist moves or shakes slightly, the rubber block 38 can buffer these external forces through its own elastic deformation, further stabilize the pressure transmission, and reduce the interference of the pulse signal due to pressure fluctuations. One end of the acquisition sensor 39 passes through the connecting frame 31 and the through slot 17 on the instrument housing 11 to connect with the processing module 21, and the other end is set as a U-shaped sleeve on the rubber block 38, which can surround the rubber block 38 more accurately to capture the pulse information transmitted through the rubber block 38. The connecting frame 31 is provided with multiple groups of lasers, which can emit laser beams to play a role in auxiliary positioning, ensuring that the patient's wrist is accurately placed under the acquisition component.

[0034] The control module 22 is located above the processing module 21 and is perpendicular to the processing module 21. This layout makes reasonable use of the internal space of the instrument. The control module 22 is provided with multiple groups of control buttons. The instrument housing 11 has key holes 15 corresponding to the control buttons. The control buttons are arranged in the key holes 15 and protrude from one side of the instrument housing 11, making it convenient for the operator to control and operate the instrument. The protruding control buttons are easy to touch and identify. The operator can easily set and adjust various parameters of the instrument through these buttons without affecting the normal operation of the instrument and the pulse collection.

[0035] The processing module 21 is provided with multiple groups 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 groups 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] When in use, guide the patient to place his arm naturally and relaxedly on the placement plate 13 on one side of the instrument, with his wrist straight and his palm facing up. As needed, connect the external device to the wiring port 16 on the instrument housing 11 through the corresponding connecting wire. Make sure that the connecting wire plug is connected to the wiring port 16 without looseness. Turn on the power of the instrument, and the indicator light on the control module 22 of the instrument 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 parameter setting interface of the instrument. According to the specific situation and diagnostic needs of the patient, set appropriate parameters such as pressure range and acquisition frequency. For example, for patients with weak constitution, the pressure range can be appropriately reduced; for situations requiring more detailed pulse analysis, the acquisition frequency can be increased. Start the automatic calibration program of the instrument. The instrument will automatically control the adjustment component so that the pressure sensor 34 in the acquisition component is 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 again that the patient's wrist position is correct and stable.Press the acquisition 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 acquisition component is slowly lowered by adjusting the slider until the rubber block 38 in the acquisition component gently contacts the pulse of the patient's wrist.During the contact process, the pressure sensor 34 monitors the pressure change between the acquisition component and the skin in real time, and transmits the data to the processing module 21.The processing module 21 controls the adjustment component through the control module 22 according to the preset pressure range and algorithm, and automatically adjusts the position and pressure of the acquisition component, so that the pressure sensor 34 is always maintained at the optimal pressure value, to ensure that stable and accurate pulse information is collected.In the acquisition process, the acquisition sensor 39 continuously captures 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.
