[0045] In the medical field, pulse monitoring is a crucial tool for assessing the health of the human cardiovascular system. The pulse wave carries a wealth of information about the cardiovascular system, and analyzing this information allows for a preliminary diagnosis of cardiovascular health. However, while many instruments exist for detecting pulses, their accuracy remains insufficient, hindering the provision of reliable data for medical diagnosis.

[0046] To solve this technical problem, this utility model proposes a sound diagnostic instrument.

[0047] Please see Figures 1 to 6 In one embodiment of this utility model, the audible pulse detector includes a housing 10, a lifting drive assembly 20, and a bone conduction acquisition head 30. The housing 10 has a receiving space 11, and a guide hole 12 communicating with the receiving space 11. The lifting drive assembly 20 includes a lifting transmission component 21 and a lifting drive mechanism connected by a transmission. The lifting drive mechanism is built into the receiving space 11, and the lifting transmission component 21 passes through the guide hole 12. The bone conduction acquisition head 30 is located outside the housing 10 and is positioned at a collection point for placing the patient's wrist. The upper end of the bone conduction acquisition head 30 is connected to the lifting transmission component 21, and the lower end is used to abut against the patient's wrist to collect pulse data at the patient's wrist. This effectively improves the accuracy of pulse measurement and provides more reliable data support for medical diagnosis.

[0048] In the technical solution of this utility model, the audible pulse diagnostic instrument collects pulse data from the patient's wrist via a bone conduction acquisition head 30. This helps to obtain more accurate and effective pulse data, providing more reliable data support for medical diagnosis. The bone conduction acquisition head 30 is positioned at a corresponding acquisition point, which is where the patient's wrist rests. This allows the bone conduction acquisition head 30 to accurately locate the optimal pulse-taking position and obtain the corresponding pulse data, improving the accuracy of pulse measurement and enhancing the precision and efficiency of pulse data collection by the audible pulse diagnostic instrument. Furthermore, the bone conduction acquisition head 30 is connected to a lifting drive mechanism via a lifting transmission component 21. Driven by the lifting drive mechanism, the lifting transmission component 21 moves the bone conduction acquisition head 30 up and down relative to the acquisition point. This allows the lower end of the bone conduction acquisition head 30 to contact the patient's wrist, facilitating pulse data collection for patients with different wrist sizes, improving the accuracy and adaptability of pulse measurement, and enhancing the practicality of the audible pulse diagnostic instrument.

[0049] Specifically, the housing 10 includes a middle shell 16, an upper cover 15, and a lower cover 17. The upper cover 15 and the lower cover 17 are respectively installed on the upper and lower sides of the middle shell 16, and together with the middle shell 16, they enclose a receiving space 11 to reliably accommodate components such as the lifting drive mechanism. The middle shell 16 has a clearance space and a collection position, allowing the patient's wrist to be inserted into the clearance space and placed in the collection position for pulse measurement. In this case, a guide hole 12 is formed in the middle shell 16, and the bone conduction collection head 30 is placed within the clearance space. However, in other embodiments, the collection position can be relatively independent of the housing 10. For example, the audible stethoscope has a measurement platform located below the housing 10. In this case, the collection position is located on the measurement platform and below the bone conduction collection head 30; or the collection position is set on the table where the audible stethoscope is placed, as long as the collection position corresponds to the bone conduction collection head 30, ensuring that the bone conduction collection head 30 collects pulse data from the patient's wrist at the collection position.

[0050] To ensure accurate pulse data acquisition, at least one bone conduction acquisition head 30 is provided. In this embodiment, three bone conduction acquisition heads 30 are arranged side by side. The spacing between the three bone conduction acquisition heads 30 corresponds to the three pulse positions (cun, guan, chi) to obtain accurate pulse data. Of course, in other embodiments, four bone conduction acquisition heads 30 may also be provided.

[0051] Please see Figures 2 to 5In an embodiment of this utility model, the bone conduction acquisition head 30 includes an acquisition head shell and a bone conduction microphone 31 disposed within the acquisition head shell. The bone conduction microphone 31 has a downward-facing pickup surface 311, wherein the pickup surface 311 of the bone conduction microphone 31 can be directly facing the pulse-taking position on the inner side of the patient's wrist. The acquisition head shell is used to fix and support the bone conduction microphone 31 and connect to the lifting transmission component 21. Then, under the drive of the lifting drive mechanism, the lifting transmission component 21 drives the bone conduction acquisition head 30 to move downward, so that the pickup surface 311 of the bone conduction microphone 31 directly or indirectly presses against the pulse-taking position on the patient's wrist, specifically the cun-kou pulse on the inner side of the wrist. With this configuration, the pickup surface 311 of the bone conduction microphone 31 can effectively sense the pulse at the wrist, thereby obtaining accurate pulse data.

[0052] Furthermore, the bone conduction acquisition head 30 also includes a PCB 35 electrically connected to the bone conduction microphone 31. The PCB 35 is fixed inside the acquisition head housing to ensure the normal operation of the bone conduction microphone 31. It can then sense the pulse at the wrist through the pickup surface 311 and generate an accurate pulse signal. The PCB 35 is also connected to the signal processing motherboard 60 of the oscilloscope. At this time, the PCB 35 can be connected to the signal processing motherboard 60 through the data cable 61, or the PCB 35 can be wirelessly connected to the signal processing motherboard 60. The bone conduction microphone 31 transmits the pulse signal through the PCB 35 to the signal processing motherboard 60 for processing into pulse data. This pulse data can be processed and saved into visual data graphs, etc., to provide more reliable data support for medical diagnosis and facilitate patients and doctors to obtain relevant information.

[0053] The PCB35 can be connected to the bone conduction microphone 31 via a flexible flat cable 36, i.e., the bone conduction microphone 31 is soldered to one end of the flexible flat cable 36 and the other end is plugged into the PCB35; the PCB35 can be installed inside the acquisition head housing by means of screw connection, snap-fit ​​fixation, etc.; the installation methods of the signal processing motherboard 60 and the housing 10 include but are not limited to screw connection, snap-fit ​​connection, and inlay fit.

[0054] Please see Figure 3In an embodiment of this utility model, the acquisition head housing includes a shell portion 32 and a cover portion 33 connected together. The end of the shell portion 32 away from the cover portion 33 is connected to the lifting transmission component 21. The cover portion 33 has a through hole 331 exposing the bone conduction microphone 31. A diaphragm 34, which is in contact with the pickup surface 311 of the bone conduction microphone 31, is embedded in the through hole 331. It is understood that the cover portion 33 covers the lower part of the shell portion 32, defining the space for installing the bone conduction microphone 31, PCB 35, flexible flat cable 36, etc. The PCB 35 is fixed inside the shell portion 32, reliably protecting the bone conduction microphone 31 and PCB 35, ensuring the safe use of the bone conduction acquisition head 30, and improving the service life of the bone conduction acquisition head 30. The through hole 331 in the cover portion 33 exposes the bone conduction microphone 31, facilitating its proximity to the acquisition head. To detect the pulse at the wrist, a diaphragm 34 is embedded within the through-hole 331. The diaphragm 34 is attached to the pickup surface 311 of the bone conduction microphone 31. At this time, the pickup surface 311 of the bone conduction microphone 31 contacts the patient's wrist through the diaphragm 34 to measure the pulse. The diaphragm 34 separates the bone conduction microphone 31 from the patient's wrist. Because the diaphragm 34 is a flexible structure, it effectively reduces the possibility of damaging the patient's skin and the bone conduction microphone 31, reducing discomfort during pulse taking. At the same time, it helps the bone conduction microphone 31 to efficiently detect the pulse at the wrist, improving the accuracy of pulse data acquisition. The diaphragm 34 can be fixed to the cover 33 as a whole by means of adhesive bonding, pressing, etc., so that the cover 33 can reliably support the diaphragm 34 and reliably cover the through-hole 331, reducing the risk of diaphragm 34 failure and facilitating the connection between the diaphragm 34 and the bone conduction microphone 31. However, in other embodiments, the cover 33 does not have a through hole 331 and is a flexible structure. In this case, the bone conduction microphone 31 is attached to the surface of the cover 33 facing the shell 32.

[0055] Please see Figure 2 and Figure 6 In this embodiment of the invention, the lifting drive mechanism is fixed inside the housing 10 by a bracket 24. The bracket 24 has a through hole 2422 for the lifting transmission component 21 to pass through, which reliably enables the assembly of the lifting drive mechanism in the storage space 11, facilitates stable driving of the lifting transmission component 21 and the bone conduction acquisition head 30, and reliably ensures the assembly and driving of the lifting transmission component 21. The connection methods between the bracket 24 and the housing 10 include, but are not limited to, screw connection, tenon and mortise connection, and snap-fit ​​connection.

[0056] Specifically, in an embodiment of this utility model, the lifting drive mechanism includes a drive motor 23 and a gear 22 connected by transmission. The lifting transmission component 21 is provided with a toothed structure 211 that meshes with the gear 22. Furthermore, through the meshing transmission between the toothed structure 211 and the gear 22, under the drive of the drive motor 23, the gear 22 drives the lifting transmission component 21 to perform lifting motion through the toothed structure 211. At this time, the lifting transmission component 21 can be configured as a rack or a lead screw. Of course, in other embodiments, the lifting drive assembly 20 includes, but is not limited to, a pneumatic or hydraulic cylinder transmission mechanism or a linkage transmission mechanism.

[0057] When the lifting transmission component 21 is configured as a rack, the gear 22 is located on the side of the rack with the toothed structure 211, and is connected to the drive motor 23 via a drive shaft; the bracket 24 includes a first mounting part 241 and a second mounting part 242 connected together. The first mounting part 241 has a first mounting groove 2411 for receiving the drive motor 23, and the second mounting part 242 has a second mounting groove 2421 for receiving the gear 22. The drive motor 23 is connected to the rack via a drive shaft 25. The gear 22, and the second mounting groove 2421 also have the through hole 2422. The second mounting groove 2421 and the first mounting groove 2411 can be connected through the mounting through hole, which can be adapted to the drive shaft 25, that is, have a diameter approximately the same as the drive shaft 25, or the mounting through hole can allow part of the drive motor 23 to pass through, thereby ensuring the drive connection between the drive motor 23 and the gear 22. The through hole 2422 penetrates the bottom of the second mounting groove 2421 and is adapted to the outer contour of the lifting transmission component 21. Furthermore, the bracket 24 is configured as a frame bracket 24, which saves processing and material costs and reduces the overall weight while satisfying the support and fixation of the lifting drive component 20, etc.

[0058] Please see Figure 2 and Figure 4In this embodiment of the invention, the housing 10 is provided with a guide rail 14 located in the guide through hole 12. A guide channel is formed within the guide rail 14 for the lifting transmission component 21 to pass through. On one hand, the guide channel guides the lifting transmission component 21, ensuring the reliability of the lifting transmission component 21 in moving the bone conduction acquisition head 30 towards the acquisition position, thus improving the accuracy and efficiency of pulse measurement. On the other hand, while ensuring the smooth passage of the lifting transmission component 21 through the guide channel, it constrains the movement trajectory of the lifting transmission component 21, reducing the risk of swaying or deformation caused by the length of the lifting transmission component 21, improving the stability of the bone conduction acquisition head 30's movement, which is beneficial for pulse perception and further improves the accuracy and efficiency of pulse measurement. The guide rail 14 and the housing 10 are an integral structure and can be fixed into a whole by means of bonding, threaded connection, welding, or insertion, improving the connection strength between the guide rail 14 and the housing 10.

[0059] Furthermore, in a further embodiment of this utility model, the guide rail 14 on the housing 10 is supported below the bracket 24. On the one hand, this enhances the assembly reliability of the bracket 24 within the housing 10, ensuring smooth driving of the lifting drive mechanism to the lifting transmission component 21. On the other hand, the through hole 2422 on the bracket 24 connects to the guide channel, extending the guide path and further improving the accuracy and acquisition efficiency of pulse measurement. The bracket 24 can be placed on top of the guide rail 14, and / or fixed to the guide rail 14 using a plug-in structure or snap fasteners to enhance the connection between the bracket 24 and the guide rail 14.

[0060] Please see Figure 3 In an embodiment of this utility model, the oscilloscope further includes a pressure sensor 40 disposed between the bone conduction acquisition head 30 and the lifting transmission component 21. The pressure sensor 40 is used to assist in regulating the pressure applied by the bone conduction acquisition head 30 to the patient's wrist. That is, through the feedback of the pressure sensor 40, the downward pressure of the bone conduction acquisition head 30 can be precisely controlled, thereby adjusting the pressure applied by the bone conduction acquisition head 30 to the patient's wrist, thereby reducing the possibility of discomfort during pulse measurement.

[0061] The bone conduction acquisition head 30 is connected to the pressure sensor 40, and the pressure sensor 40 is connected to the lifting transmission component 21 via a plug-in connection. This increases the effective contact area between adjacent components, improving the connection strength and reliability between the bone conduction acquisition head 30 and the pressure sensor 40, and between the pressure sensor 40 and the lifting transmission component 21. Alternatively, the bone conduction acquisition head 30 and the pressure sensor 40, and the pressure sensor 40 and the lifting transmission component 21, can also be connected using adhesive bonding or threaded connections.

[0062] Please see Figure 2In an embodiment of this utility model, the pulse diagnosis device further includes a wrist sensor, which is used to monitor whether the patient's wrist is placed in the acquisition position. It can be understood that when the patient's wrist is placed in the acquisition position, the wrist sensor detects and obtains the information that the wrist is placed in the acquisition position. Then, the lifting drive mechanism is controlled to move. At this time, the drive motor 23 drives the rack to move down through the gear 22. The bone conduction acquisition head 30 gradually approaches and presses against the patient's wrist as the rack moves down, so as to achieve the purpose of pulse diagnosis and improve the automation level of the pulse diagnosis device.

[0063] Specifically, in an embodiment of this invention, the wrist sensor is configured as a first infrared sensor 50 located at the acquisition position. The first infrared sensor 50 is positioned directly below the bone conduction acquisition head 30, thereby ensuring that the pulse-taking position at the patient's wrist is between the first infrared sensor 50 and the bone conduction acquisition head 30, thus guaranteeing the accuracy and efficiency of pulse measurement. The first infrared sensor 50 can be an active infrared sensor, which detects the presence of the pulse-taking position at the patient's wrist by emitting infrared light and measuring the amount of reflected light. Of course, in other embodiments, the wrist sensor may also be configured as, but is not limited to, a temperature sensor, a thermal infrared sensor, or a pressure sensor.

[0064] More specifically, in an embodiment of this invention, the acquisition position is configured as a recessed groove 13 formed in the housing 10. This recessed groove 13 can accommodate the patient's wrist, allowing the patient to quickly locate the acquisition position and placing the pulse-taking position above the wrist sensor, thus serving as an indicator and improving the efficiency of pulse measurement. Of course, the acquisition position can also be a corresponding text or graphic indicator structure.

[0065] Please see Figure 2 and Figure 4 In an embodiment of this utility model, the audible stethoscope further includes a signal processing motherboard 60, which is communicatively connected to the bone conduction acquisition head 30 and is disposed within the housing 10. The audible stethoscope also includes a host 70, which is communicatively connected to the signal processing motherboard 60. It is understood that the PCB 35 within the bone conduction acquisition head is connected to the signal processing motherboard 60 via a data cable 61 or wireless communication, so that the bone conduction microphone 31 transmits the measured pulse signal through the PCB 35 to the signal processing motherboard 60 for processing into pulse data. This pulse data can be saved to the host 70 and presented as a visual data graph, making it convenient for patients and doctors to obtain relevant information and providing more reliable data support for medical diagnosis.

[0066] In one embodiment, the signal processing motherboard 60 is provided with a wireless communication module 62, which is connected to the host 70. In another embodiment, the signal processing motherboard 60 and the host 70 are wired to achieve data transmission.

[0067] When the bone conduction acquisition head 30 is connected to the signal processing motherboard 60 via the data cable 61, the lifting transmission component 21 has a passageway 212 for the data cable 61 to pass through. This ensures the communication connection between the PCB 35 and the signal processing motherboard 60, makes reasonable use of the internal space of the lifting transmission component 21, constrains the routing of the data cable 61, and standardizes the direction of the data cable 61. In addition, it can reasonably reduce the weight of the lifting transmission component 21 and reduce the amount of material used while ensuring the driving effect of the lifting transmission component 21.

[0068] Please see Figure 1 In an embodiment of this utility model, the host 70 includes a display screen 71, a second infrared sensor 72, and a camera 73 that are communicatively connected to the signal processing motherboard 60. The second infrared sensor 72 and the camera 73 are disposed around the display screen 71 and are used to automatically collect and identify patient information, thereby improving the automation level of the audible diagnostic instrument.

[0069] The main unit 70 is set independently from the housing 10. In this case, the housing 10, the bone conduction acquisition head 30 and the lifting drive assembly 20 constitute a pulse acquisition device, and the main unit 70 constitutes a data integration and display device. This allows for the setting of one pulse acquisition device corresponding to one data integration and display device, or the setting of multiple pulse acquisition devices corresponding to one data integration and display device, to realize the detection and collection of pulse data. The main unit 70 can also be set on the housing 10 to realize the integration of the audible diagnostic instrument, which facilitates the transportation of the audible diagnostic instrument.

[0070] The second infrared sensor 72 is used to detect whether someone is approaching the host 70, and the camera 73 can be used to detect whether someone is approaching the host 70 and / or to obtain the patient's facial information. The combined use of the two can enable the display screen 71 to quickly display pulse data related to the patient.

[0071] Optionally, in an embodiment of this utility model, the host 70 further includes a microphone and a speaker for guiding the patient to complete pulse data acquisition. This allows for voice prompts to the patient indicating that pulse measurement has begun or ended, facilitating rapid acquisition of pulse data from multiple patients. The host 70 has a microphone port 74 corresponding to the microphone and a speaker port 75 corresponding to the speaker, ensuring that the voice prompts emitted by the microphone and speaker are amplified beyond the host 70, guaranteeing the patient's access to the relevant information.

[0072] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
