Description

Technical Field

[0001] This utility model relates to the field of medical instrument technology, and in particular to a pulse sensor and pulse diagnosis device. Background Technology

[0002] Pulse diagnosis is an important technique in Traditional Chinese Medicine (TCM) with a history of over a thousand years, accumulating a wealth of valuable experience. Commonly used pulse diagnosis methods include the Cun-Kou method, which involves pulsating at the radial artery on the wrist. This method is divided into three parts: Cun, Guan, and Chi. The Cun part, near the first phalanx of the hand, corresponds to the respiratory and circulatory systems; the Guan part, near the middle phalanx, corresponds to the digestive and hematopoietic systems; and the Chi part, near the third phalanx of the elbow, corresponds to the urinary and reproductive systems. Information about the corresponding system can be obtained from the pulse at different locations. Depending on the pressure applied during pulse diagnosis, it is further divided into superficial, medium, and deep palpation. Superficial palpation involves gently pressing the skin surface to feel the superficial pulse, indicating superficial symptoms (such as the early stages of a cold). Medium palpation involves gradually increasing the pressure to the subcutaneous muscle layer to perceive the pulse's strength and weakness, indicating diseases in the middle layer of the body. Deep palpation involves pressing firmly to the tendons and bones to feel the deep pulse, indicating internal symptoms (such as kidney deficiency and blood stasis).

[0003] With the continuous development of technology, various types of pulse diagnosis devices have emerged on the market. They can be broadly classified into photoelectric, ultrasonic, and flexible electronic types according to their technology. Photoelectric devices, such as photoplethysmography, measure changes in blood vessel volume through light reflection. Ultrasonic devices, such as ultrasonic blood flow detectors, analyze blood flow velocity and direction through the Doppler effect. Flexible electronic devices, such as wearable pulse patches, use flexible sensors that adhere to the skin for dynamic detection. Traditional pulse diagnosis technology, on the other hand, judges disease information by sensing the frequency and strength of the pulse, which is fundamentally different from the diagnostic methods of existing pulse diagnosis devices. This results in the pulse diagnosis of existing pulse diagnosis devices not being very accurate. Utility Model Content

[0004] In view of this, the present invention provides a pulse sensor and pulse diagnosis device that can better reflect the pulse condition.

[0005] On one hand, this application provides a pulse sensor, including a housing, a conductive electrode plate located inside the housing, an elastic diaphragm disposed at a distance from the conductive electrode plate, and a push rod connected to the side of the elastic diaphragm away from the conductive electrode plate. The conductive electrode plate is fixed relative to the housing. The housing has an opening through it at a position corresponding to the push rod. The end of the push rod away from the elastic diaphragm protrudes through the opening to the outside of the housing. The push rod is used to contact the pulse diagnosis site and transfer the energy of the pulse to the elastic diaphragm, so that the elastic diaphragm vibrates relative to the conductive electrode plate under the action of the pulse.

[0006] In some embodiments, the elastic diaphragm includes a vibrating portion connected to the top rod and a fixing portion connected to the edge of the vibrating portion. The vibrating portion is disposed opposite to the conductive electrode plate at a distance. The thickness of the fixing portion is greater than the thickness of the vibrating portion and is fixed relative to the housing, so that the vibrating portion and the opening are disposed at a distance from each other.

[0007] In some embodiments, a gasket is also included, the gasket being located between the fixing portion and the conductive electrode plate.

[0008] In some embodiments, the vibrating part is a conductive part, or the surface of the vibrating part is provided with a conductive layer.

[0009] In some embodiments, a limiting member is further included, which is located outside the housing and near the opening, and the length of the portion of the top rod outside the opening is greater than the length of the limiting member along the extension direction of the top rod.

[0010] In some embodiments, an elastic element is further included, the elastic element being located outside the housing and surrounding the outer periphery of the top rod; or,

[0011] The elastic element is located between the elastic diaphragm and the conductive electrode plate.

[0012] In some embodiments, a flexible membrane is also included, which is fixed to the outside of the housing and covers the opening, and the end of the top rod away from the elastic diaphragm is connected to the flexible membrane.

[0013] In some embodiments, the device further includes a circuit board and a conductive connector, the circuit board being located on the side of the conductive electrode plate away from the elastic diaphragm, and the conductive connector being located inside the housing and connecting the circuit board and the conductive electrode plate.

[0014] In some embodiments, the conductive connector and the conductive electrode plate are spaced apart from the housing, and an insulating ring is provided inside the housing, the insulating ring surrounding the outer periphery of the conductive connector and the conductive electrode plate.

[0015] On the other hand, this application also provides a pulse diagnosis device, including a pulse diagnosis table, a pressure control module installed on the pulse diagnosis table, an identification and positioning module connected to the pressure control module, and a pulse diagnosis sensor as described above. The identification and positioning module is used to identify the pulse diagnosis site, the pressure control module is connected to the pulse diagnosis sensor, and the pressure control module is used to drive the pulse diagnosis sensor to move to the pulse diagnosis site and control the pressure applied by the pulse diagnosis sensor to the pulse diagnosis site.

[0016] The pulse sensor provided by this utility model has a conductive electrode plate and an elastic diaphragm set inside the housing. The conductive electrode plate and the elastic diaphragm are arranged at intervals to form a capacitor structure. One end of the push rod is connected to the elastic diaphragm, and the other end protrudes to the outside of the housing through the opening. When the push rod contacts the pulse point and applies a certain pressure to the pulse point, the energy generated by the pulse at the pulse point is transmitted to the elastic diaphragm through the push rod, causing the elastic diaphragm to vibrate under the action of the pulse and drive the push rod to move together. When the elastic diaphragm vibrates, the distance between it and the conductive electrode plate changes, thereby changing the capacitance between the elastic diaphragm and the conductive electrode plate. Based on the change in capacitance, the frequency and strength of the pulse can be measured, thus more accurately reflecting the true state of the pulse. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0026] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0027] Please see Figures 1 to 4 An embodiment of this utility model provides a pulse sensor 10, including a housing 12, a conductive electrode plate 14, an elastic diaphragm 16, and a push rod 18. The conductive electrode plate 14 and the elastic diaphragm 16 are respectively located inside the housing 12, and the conductive electrode plate 14 is fixed relative to the housing 12. The elastic diaphragm 16 and the conductive electrode plate 14 are spaced apart and opposite to each other, forming a structure similar to a capacitor. The push rod 18 is connected to the side of the elastic diaphragm 16 away from the conductive electrode plate 14. The housing 12 has an opening 20 through the push rod 18 at the position corresponding to the push rod 18. The end of the push rod 18 away from the elastic diaphragm 16 passes through the opening 20 and protrudes to the outside of the housing 12 so as to contact the pulse diagnosis site.

[0028] When the end of the push rod 18 furthest from the elastic diaphragm 16 contacts the pulse diagnosis site and applies a certain pressure, the energy generated by the pulse at the diagnosis site is transmitted to the elastic diaphragm 16 through the push rod 18. The elastic diaphragm 16 vibrates relative to the conductive electrode plate 14 under the influence of the pulse. During vibration, the elastic diaphragm 16 deforms, causing a change in the distance between the vibrating part and the conductive electrode plate 14. This changes the capacitance gap of the capacitor formed by the conductive electrode plate 14 and the elastic diaphragm 16, thus altering the capacitance between them. The frequency and magnitude of this capacitance change allow for the measurement of the pulse frequency and intensity, providing a more accurate reflection of the true pulse condition. Furthermore, the pulse sensor 10 detects the pulse by forming a capacitor with the conductive electrode plate 14 and the elastic diaphragm 16, resulting in a relatively simple overall structure that helps reduce production costs.

[0029] Optionally, the pulse diagnosis site is the radial artery at the wrist. The pressure applied to the pulse diagnosis site by the lever 18 is the pulse diagnosis force, which is divided into three types: superficial, medium, and deep. The superficial pulse diagnosis force is 10g-50g, the medium pulse diagnosis force is 50g-150g, and the deep pulse diagnosis force is 150g-300g. The pulse diagnosis force can be selected according to different groups of people, including those of different ages, deformities, and diseases.

[0030] When the push rod 18 applies pressure to the pulse diagnosis site, the pulse diagnosis site generates a reaction force on the push rod 18. This reaction force is transmitted to the elastic diaphragm 16 through the push rod 18, causing the elastic diaphragm 16 to deform. The distance between the deformed part of the elastic diaphragm 16 and the conductive electrode plate 14 decreases. Since the distance is negatively correlated with capacitance, the greater the pressure applied by the push rod 18 to the pulse diagnosis site, the greater the degree of deformation of the elastic diaphragm 16, the smaller the distance between its deformed part and the conductive electrode plate 14, and the greater the capacitance between the elastic diaphragm 16 and the conductive electrode plate 14.

[0031] The specific shape of the housing 12 is not limited, such as circular, square, etc. In one embodiment, the housing 12 includes a base plate 22 and a surrounding wall 24 surrounding the periphery of the base plate 22. The surrounding wall 24 is annular and forms a cavity with the base plate 22. The conductive electrode plate 14 and the elastic diaphragm are housed in the cavity to protect the conductive electrode plate 14 and the elastic diaphragm 16.

[0032] The elastic diaphragm 16 is located between the conductive electrode plate 14 and the base plate 22. The opening 20 is located in the middle of the base plate 22. The end of the top rod 18 away from the elastic diaphragm 16 passes through the opening 20 and extends to the outside of the base plate 22.

[0033] The inner diameter of the opening 20 is larger than the outer diameter of the push rod 18, so that there is a certain distance between the outer surface of the push rod 18 and the inner surface of the opening 20, preventing the push rod 18 from contacting the inner surface of the opening 20 and generating friction to hinder the movement of the push rod 18. The push rod 18 also moves with the elastic diaphragm 16, thereby preventing the push rod 18 from contacting the inner surface of the opening 20 and affecting the vibration of the elastic diaphragm 16.

[0034] In one embodiment, the elastic diaphragm 16 includes a vibrating part 26 and a fixing part 28 connected to the edge of the vibrating part 26. The vibrating part 26 is connected to the top rod 18 and is spaced apart from the conductive electrode plate 14, thereby forming a capacitor structure with the conductive electrode plate 14. The thickness of the fixing part 28 is greater than the thickness of the vibrating part 26 and is fixed relative to the housing 12 to support the vibrating part 26, so that the vibrating part 26 and the opening 20 are spaced apart from each other. By setting the elastic diaphragm 16 to include the vibrating part 26 and the fixing part 28, the vibrating part 26 has a smaller thickness and relatively weaker strength, thus having better elasticity. The intensity of the pulse is not too high, and the lower elasticity of the vibrating part 26 is conducive to better sensing the pulse and vibrating. The fixing part 28 has a larger thickness and relatively greater strength. The elastic diaphragm 16 is fixed to the housing 12 by the fixing part 28, which helps to enhance the reliability of the connection between the elastic diaphragm 16 and the housing 12, and avoids the elastic diaphragm 16 from detaching from the housing 12 due to the vibration of the vibrating part 26, thus achieving the effect of balancing connection strength and convenient vibration.

[0035] Optionally, the fixing part 28 is fixed to the bottom plate 22 of the housing 12, so that the vibrating part 26 is suspended relative to the bottom plate 22, which facilitates the vibration of the vibrating part 26. The top rod 18 is connected to the middle position of the vibrating part 26.

[0036] Understandably, the fixing part 28 can be an annular structure surrounding the vibrating part 26, or it can be a plurality of fixing blocks spaced apart circumferentially along the fixing part 28.

[0037] The vibrating part 26 can be a conductive part made of a conductive material such as metal, or the surface of the vibrating part 26 can have a conductive layer, as long as it can cooperate with the conductive electrode plate 14 to form a capacitor structure. In an optional example, the conductive electrode plate 14 is made of a metal material, thereby having a conductive effect, that is, the conductive electrode plate 14 is a metal electrode plate. The vibrating part 26 is preferably made of a material with good elasticity and capable of being plated with a metal thin film. The surface of the vibrating part 26 has a conductive layer (not shown), for example, a metal layer is plated on the surface of the vibrating part 26 to form a conductive layer. Compared with the vibrating part 26 being made entirely of a conductive material, it is beneficial to reduce the overall strength of the vibrating part 26, making it easier to vibrate.

[0038] The power supply method of the conductive electrode plate 14 is not limited, such as electret type, post-Bias power-on, and capacitance value change test without power-on.

[0039] In one embodiment, a gasket 30 is provided between the fixing part 28 and the conductive electrode plate 14 to separate the elastic diaphragm 16 from the conductive electrode plate 14. At the same time, the gasket 30 is an insulating gasket 30, which can prevent the elastic diaphragm 16 from contacting the conductive substrate and causing a short circuit.

[0040] Understandably, the gasket 30 can be an annular gasket 30, with its axial sides respectively in contact with the periphery of the conductive electrode plate 14 and the elastic diaphragm 16, or it can be a plurality of gaskets 30 individually spaced along the circumference of the conductive electrode plate 14.

[0041] In one embodiment, the pulse sensor 10 further includes a circuit board 32 and a conductive connector 34. The circuit board 32 is located on the side of the conductive electrode plate 14 away from the elastic diaphragm 16 and is spaced apart from the conductive electrode plate 14. The conductive connector 34 is located inside the housing 12 and connects the circuit board 32 and the conductive electrode plate 14. Optionally, the end of the enclosure 24 away from the bottom plate 22 is open, and the circuit board 32 is located at the open end of the enclosure 24 to connect with external components. The conductive electrode plate 14 is electrically connected to the circuit board 32 through the conductive connector 34. The circuit board 32 can perform impedance conversion and signal processing. Through the cooperation of the conductive electrode plate 14 and the elastic diaphragm 16, the circuit board 32 can convert the pulse information into an electrical signal to obtain the pulse status.

[0042] The specific type of conductive connector 34 is not limited, as long as it can connect the circuit board 32 and the conductive electrode plate 14, such as a spring, a pin, or a connecting electrode ring. In this embodiment, the conductive connector 34 is a connecting electrode ring, with its axial sides connected to the conductive electrode plate 14 and the circuit board 32 respectively, achieving electrical connection while also supporting the circuit board 32.

[0043] Optionally, the conductive electrode plate 14 and the circuit board 32 are arranged parallel to each other at intervals, and the connecting electrode rings are perpendicular to the conductive electrode plate 14 and the circuit board 32 respectively.

[0044] An insulating ring 36 is provided inside the housing 12. The insulating ring 36 is made of insulating material and has an insulating effect. The conductive connector 34 and the conductive electrode plate are both spaced apart from the housing 12, and the insulating ring 36 surrounds the outer periphery of the conductive connector 34 and the conductive electrode plate. The insulating ring 36 can separate the housing 12 from the conductive electrode plate 14 and the conductive connector 34, preventing the housing 12 from contacting the conductive connector 34 or the conductive electrode plate 14 and forming a connection.

[0045] In one embodiment, the pulse sensor 10 further includes a limiting member 38, which is located outside the housing 12 and near the opening 20. Along the extending direction of the push rod 18, the length of the portion of the push rod 18 outside the opening 20 is greater than the length of the limiting member 38; that is, the end of the push rod 18 away from the elastic diaphragm 16 protrudes from the side of the limiting member 38 away from the housing 12. Because the push rod 18 protrudes from the limiting member 38, it first contacts the pulse diagnosis area. As the pressure of the push rod 18 on the pulse diagnosis area increases, the push rod 18 moves towards the interior of the housing 12, causing the elastic diaphragm 16 to deform. When the push rod 18 moves to be flush with the limiting member 38, it can no longer move towards the interior of the housing 12, thus limiting the movement distance of the push rod 18 and preventing damage to the elastic diaphragm 16 due to excessive movement of the push rod 18 towards the interior of the housing 12.

[0046] Understandably, the limiting member 38 can be a limiting ring that surrounds the outer periphery of the opening 20, or the limiting member 38 can be a limiting block provided on opposite sides of the opening 20.

[0047] In one embodiment, the pulse sensor 10 further includes a flexible diaphragm 40, which is fixed to the outside of the housing 12 and covers the opening 20 to prevent external dust and other contaminants from entering the housing 12 through the opening 20. The end of the push rod 18 away from the elastic diaphragm 16 is connected to the flexible diaphragm 40. The flexible diaphragm 40 can deform with the movement of the push rod 18 without affecting the movement of the push rod 18, and at the same time, it can prevent the push rod 18 from directly contacting sweat and other substances on the skin.

[0048] The flexible diaphragm 40 can be directly fixed to the housing 12 or fixedly fixed to the limiting member 38, and indirectly connected to the housing 12, as long as it can cover the opening 20 and be connected to the end of the top rod 18 away from the elastic diaphragm 16.

[0049] The push rod 18 is preferably made of a lightweight material with a certain degree of rigidity, such as hard plastic or resin. The shape of the push rod 18 can be circular, square, or other shapes, and the push rod 18 can be a hollow structure or a solid structure, as long as it can transmit the energy generated by the pulse to the elastic diaphragm 16.

[0050] In one embodiment, the pulse sensor 10 further includes an elastic element 42. The elastic element 42 is elastic, capable of compression and deformation, and has different compression amounts under different pulse-taking forces. After pulse taking, the elastic element 42 can return to its original shape under its own elastic force and assist the push rod 18 in resetting. The elastic element 42 is preferably an elastic compression material, such as rubber or compressed foam.

[0051] The elastic element 42 can be located inside the housing 12 or outside the housing 12. For example, in Figure 1 In the illustrated embodiment, the elastic element 42 is located outside the housing 12 and surrounds the outer periphery of the top rod 18. The flexible membrane 40 wraps around the elastic element 42, meaning the elastic element 42 is located between the flexible membrane 40 and the housing 12. Figure 5 In another embodiment shown, the elastic element 42 is located inside the housing 12, between the elastic diaphragm 16 and the conductive electrode plate 14.

[0052] Please see Figure 6 This utility model also provides a pulse diagnosis device 44, including a pulse diagnosis table 46, a pressure control module 48, an identification and positioning module 50, and a pulse sensor 10 as described in the above embodiments. The pressure control module 48 is installed on the pulse diagnosis table 46, and the identification and positioning module 50 and the pulse sensor 10 are both connected to the pressure control module 48. The identification and positioning module 50 is used for the pulse diagnosis site, and the pressure control module 48 can drive the identification and positioning module 50 and the pulse sensor 10 to move relative to the pulse diagnosis table 46, so that the top rod 18 of the pulse sensor 10 contacts the pulse diagnosis site and applies corresponding pressure to the pulse diagnosis site. Since the pulse diagnosis device 44 adopts the technical solutions of all the above embodiments, it has at least the beneficial effects brought by the technical solutions of all the above embodiments, which will not be described in detail here.

[0053] Optionally, the pulse diagnosis device 44 includes three pulse diagnosis sensors 10, which are arranged in sequence. Each pulse diagnosis sensor 10 includes a push rod 18. During use, the push rods 18 of the three pulse diagnosis sensors 10 correspond to the cun, guan, and chi positions, respectively.

[0054] The pulse diagnosis table 46 includes a base 52 and a support 54. The base 52 is used to place the arm. The support 54 includes a first frame extending vertically and a second frame extending horizontally. One end of the first frame is connected to the base 52 and the other end is connected to the second frame. The pressure regulation module 48 is installed at the end of the second frame away from the first frame.

[0055] The pressure regulation module 48 can drive the pulse sensor 10 to move via a motor or cylinder, and the pulse intensity can be adjusted by controlling the movement distance. Understandably, to further improve the accuracy of the pulse intensity, a pressure sensor can also be included to detect the pulse intensity.

[0056] The identification and positioning module 50 can be a CCD (Charge-Coupled Device) camera. The CCD camera identifies the location of the radial artery by capturing images of the wrist, thereby achieving the effect of identifying the pulse diagnosis site.

[0057] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
