Description

Technical Field

[0001] This application relates to the field of medical instrument technology, and in particular to an ultrasound diagnostic device with physiological signal detection function. Background Technology

[0002] Echocardiography is considered the "gold standard" for diagnosing heart disease. When using ultrasound diagnostic equipment to examine diseases such as congenital heart disease or to perform transesophageal cardiac examinations, in addition to ultrasound images, it is generally necessary to examine the patient's physiological signals, such as electrocardiograms and phonocardiograms, to assist in diagnosis.

[0003] To obtain electrocardiogram (ECG) signals, traditional ultrasound diagnostic equipment requires an additional 3-lead ECG device. The three leads of this device must be strictly adhered to designated locations on the body surface according to standards, a process that is cumbersome and prone to connection errors. Furthermore, the lead patches may not adhere securely or may fall off. When connections are incorrect or not made, an accurate ECG cannot be obtained, thus affecting the doctor's assessment of the patient's condition. Therefore, the shortcomings and limitations of traditional ECG equipment result in low efficiency in ultrasound examinations, hindering doctors' ability to diagnose patients' conditions. Summary of the Invention

[0004] Therefore, it is necessary to provide an ultrasound diagnostic device with physiological signal detection function to address the above-mentioned technical problems.

[0005] This application provides an ultrasound diagnostic device with physiological signal detection function. The ultrasound diagnostic device includes a moving device, a signal detection device, and an ultrasound diagnostic device. The moving device is disposed on an examination table. The signal detection device is disposed on the moving device. The signal detection device is used to detect the physiological signals of the object to be examined. The ultrasound diagnostic device is connected to the signal detection device and is used to acquire ultrasound images of the object to be examined.

[0006] In one embodiment, the signal detection device is a non-contact detection device.

[0007] In one embodiment, the signal detection device is a millimeter-wave radar electrocardiogram detection device.

[0008] In one embodiment, the ultrasound diagnostic device further includes an image acquisition device and a data processing module, with the image acquisition device connected to the data processing module. The image acquisition device acquires image information of the object to be examined and transmits the image information to the data processing module. The data processing module obtains the target location of the object to be examined based on the image information and the feature information of the object.

[0009] In one embodiment, the data processing module is wirelessly connected to the mobile device. The data processing module is used to calculate a movement path based on the target location. The mobile device is used to control the signal detection device to move to the target location based on the movement path.

[0010] In one embodiment, the data processing module is wirelessly connected to the signal detection device to acquire the physiological signal and obtain a physiological image of the object under test based on the physiological signal.

[0011] In one embodiment, the ultrasound diagnostic device further includes a display module. The display module is connected to the data processing module and is used to display the physiological images.

[0012] In one embodiment, the display module is also used to display the ultrasound image.

[0013] In one embodiment, the moving device includes two mutually perpendicular movable guide rails. The two movable guide rails are disposed below the examination bed. The signal detection device is disposed at the intersection of the two movable guide rails.

[0014] In one embodiment, the ultrasound diagnostic device with physiological signal detection function further includes a first wireless transmission module. The first wireless transmission module is disposed on the examination bed. The first wireless transmission module is used to enable wireless communication connections between the mobile device, the signal detection device, the image acquisition device, and the data processing module, respectively.

[0015] The aforementioned ultrasound diagnostic equipment with physiological signal detection function includes a signal detection device used to detect the physiological signals of the subject under examination. The moving device moves on the examination table, thereby moving the signal detection device. This changes the relative distance between the signal detection device and the subject under examination. Therefore, when detecting different parts of the subject, the moving device can move the signal detection device to different locations to achieve detection of different parts of the subject.

[0016] Simultaneously, the ultrasound diagnostic device is used to perform ultrasound diagnosis. The signal detection device transmits the detected physiological signals to the ultrasound diagnostic device. At this time, based on the ultrasound image and with the physiological signals as an aid, the ultrasound diagnostic device can perform medical diagnoses such as congenital heart disease or transesophageal cardiac examination of the subject.

[0017] Therefore, the ultrasound diagnostic device with physiological signal detection function can acquire these physiological signals without the need for additional ECG lead connections or a stethoscope, greatly simplifying the doctor's procedure and overcoming the shortcomings of traditional ultrasound examinations. Furthermore, when examining the subject, it is not necessary to strictly adhere to designated locations on the body surface, enabling non-contact testing. Thus, the ultrasound diagnostic device with physiological signal detection function solves the problem of low ultrasound examination efficiency caused by unstable lead patch adhesion, incorrect connections, or detachment, making it more conducive for doctors to diagnose the subject's condition and improving diagnostic efficiency.

[0030] Please see Figure 1This application provides an ultrasound diagnostic device 100 with physiological signal detection function. The ultrasound diagnostic device 100 includes a moving device 10, a signal detection device 20, and an ultrasound diagnostic device 30. The moving device 10 is disposed on an examination bed 80. The signal detection device 20 is disposed on the moving device 10. The signal detection device 20 is used to detect the physiological signals of the object 910 to be examined. The ultrasound diagnostic device 30 is connected to the signal detection device 20, and the ultrasound diagnostic device 30 is used to acquire ultrasound images of the object 910 to be examined, and can also acquire the physiological signals detected by the signal detection device 20.

[0031] In this embodiment, the signal detection device 20 is used to detect the physiological signals of the object under examination 910. The physiological signals include electrocardiogram (ECG) signals, heart sound signals, and other signals characterizing the physiological characteristics of the object under examination 910. The signal detection device 20 can be a single physiological signal detection device or an integrated set of multiple physiological signal detection devices. When the object under examination 910 is located on the examination bed 80, the moving device 10 moves on the examination bed 80, thereby moving the signal detection device 20. Therefore, when detecting different sizes of the object under examination 910 or different locations of the parts to be detected, the moving device 10 can move the signal detection device 20 to the designated detection location to achieve detection of the corresponding parts of the object under examination 910. Furthermore, when detecting different parts of the object under examination 910, the moving device 10 can move the signal detection device 20 to different locations to achieve detection of different parts of the object under examination 910.

[0032] Simultaneously, the ultrasound diagnostic device 30 is used to perform ultrasound diagnosis, applying ultrasound detection technology to the object 910 to obtain ultrasound images. The ultrasound diagnostic device 30 is connected to the signal detection device 20, which can be a wireless or wired communication connection, as long as signal transmission is achieved. The signal detection device 20 transmits the detected physiological signals to the ultrasound diagnostic device 30. At this time, based on the ultrasound images and with the physiological signals as an aid, the ultrasound diagnostic device 30 can perform medical diagnoses such as congenital heart disease or transesophageal cardiac examination of the object 910.

[0033] Therefore, the ultrasound diagnostic device 100 with physiological signal detection function can acquire the physiological signals without the need for additional ECG lead wires or a stethoscope, greatly simplifying the doctor's operation and compensating for the shortcomings of physiological signal devices in traditional ultrasound examinations. Simultaneously, when examining the subject 910, it is not necessary to strictly adhere to the designated locations on the human body surface according to standards, enabling non-contact detection. Thus, the ultrasound diagnostic device 100 with physiological signal detection function solves the problem of low ultrasound examination efficiency caused by unstable lead patch adhesion, incorrect connection, or detachment, making it more conducive for doctors to diagnose the condition of the subject 910 and improving diagnostic efficiency.

[0034] In one embodiment, the object to be examined 910 is a human body. When the patient lies flat on the examination bed 80, the moving device 10 moves on the examination bed 80, causing the signal detection device 20 to move, thereby enabling the detection of the patient's physiological signals.

[0035] In one embodiment, the signal detection device 20 is a non-contact detection device.

[0036] In this embodiment, the non-contact detection device can be understood as follows: the signal detection device 20 does not contact the object under test 910, and it is not necessary to attach the signal detection device 20 to the surface of the object under test 910 for measurement. In this case, the non-contact detection device avoids problems caused by unstable or fallen lead patch adhesion, incorrect or missing connections, etc., thus improving the ultrasound examination efficiency of the ultrasound diagnostic device 100 with physiological signal detection function and compensating for the shortcomings of physiological signal devices in traditional ultrasound examinations.

[0037] In one embodiment, the signal detection device 20 is a millimeter-wave radar electrocardiogram detection device.

[0038] In this embodiment, the millimeter-wave radar electrocardiogram (ECG) detection device acquires the physiological signals of the subject 910 using millimeter-wave radar. The millimeter-wave radar ECG detection device has advantages such as resistance to electronic interference, clutter interference, and multipath reflection interference, which is beneficial for obtaining accurate physiological signal data. Specifically, based on the Doppler radar detection principle, the millimeter-wave radar ECG detection device transmits a linear frequency modulated continuous wave signal during operation, receives the reflected echo signal, and detects and obtains the physiological signals of the subject 910 by demodulating and amplifying the echo signal.

[0039] In one embodiment, the signal detection device 20 includes an electrocardiogram sensor for acquiring dynamic electrocardiogram data, specifically including a 3-lead or 5-lead electrocardiogram sensor, a preamplifier, an active bandpass filter, a shielded drive module, a power supply module, an A / D converter, a wireless data transmitter, and a synchronization signal trigger, etc.

[0040] In one embodiment, the signal detection device 20 further includes a heart sound sensor for acquiring dynamic heart sound data, which may specifically include a piezoelectric sensor, a preamplifier, an active bandpass filter, a power module, a wireless data transmitter, an A / D converter, and a synchronization signal trigger.

[0041] In one embodiment, the signal detection device 20 further includes a reflective photoelectric sensor for acquiring dynamic pulse wave data signals, specifically including two or four reflective photoelectric sensors, an active bandpass filter, a preamplifier, a power supply module, an A / D converter, a wireless data transmitter, a synchronization signal trigger, and a relative position sensor, etc.

[0042] In one embodiment, the ultrasound diagnostic device 30 includes a probe, a main unit, a display, and other components. The main unit includes hardware, imaging software, a user interface, and other components.

[0043] Please see Figure 2 In one embodiment, the ultrasound diagnostic device 30 includes an input module 310. The input module 310 is used to input the feature information of the object to be examined 910 and transmit the feature information to the data processing module 320.

[0044] In this embodiment, the feature information includes height, age, name, ID, gender, weight, etc. The feature information is then transmitted to the ultrasound diagnostic device 30 via the input module 310. Subsequently, the ultrasound diagnostic device 30 uses the feature information to determine the characteristics of the object to be examined 910, preparing for subsequent ultrasound diagnosis.

[0045] In one embodiment, the input module 310 can be further used to input the examination mode or examination site of the object to be examined 910. The examination mode can be abdomen, small organs, heart, blood vessels, gynecology, obstetrics, etc. Furthermore, the examination mode can be further subdivided; for example, small organs can be subdivided into thyroid gland, breast, etc. At this time, depending on the examination mode, the data processing module 320 can determine whether the signal detection device 20 needs to be activated, and automatically turn the signal detection device 20 on or off. For example, when examining the heart-related parts of the object to be examined 910, the data processing module 320 controls the signal detection device 20 to be turned on. When examining the abdomen, small organs, blood vessels, or other parts of the object to be examined that are not related to the heart, the data processing module 320 controls the signal detection device 20 to be turned off.

[0046] Therefore, depending on the examination mode, the data processing module 320 controls the automatic opening or closing of the signal detection device 20, which greatly simplifies the doctor's operation process and improves diagnostic efficiency.

[0047] Please see Figure 2 In one embodiment, the ultrasound diagnostic device 100 with physiological signal detection function further includes an image acquisition device (not shown in the figure). The ultrasound diagnostic device 30 includes a data processing module 320, and the image acquisition device is connected to the data processing module 320. The image acquisition device (not shown in the figure) is used to acquire image information of the object to be examined 910 and transmit the image information to the data processing module 320. The data processing module 320 is used to obtain the target position of the object to be examined 910 based on the image information and the feature information of the object to be examined.

[0048] In this embodiment, the image information includes the relative position of the object to be examined 910 and the examination bed 80, which can also be understood as the position of the object to be examined 910 within the examination bed 80, such as slightly to the left, right, top, or bottom. The image of the object to be examined 910 is acquired by the image acquisition device, and processed by the data processing module 320 to obtain corresponding image information. This image information is used to determine the position of the object to be examined 910 within the examination bed 80. The input module 310 is used to input the feature information of the object to be examined 910 and transmit it to the data processing module 320. The data processing module 320 calculates the target position of the object to be examined 910 based on the image information and the feature information. The target position is the position where the object to be examined 910 needs to undergo physiological signal detection by the signal detection device 20. The data processing module 320 obtains the position of the object to be examined 910 within the examination bed 80 based on the image information.

[0049] For example, the data processing module 320 first determines the age group and gender of the subject 910 based on its age and gender. Then, the data processing module 320 calculates the location of the subject 910's heart based on the body size information of Chinese adults / minors and human anatomical characteristics. The body size information for Chinese adults / minors can be found in GB / T 10000 and GB / T 26158.

[0050] At this time, the data processing module 320 calculates the current heart position of the subject 910 based on its own heart position and its position within the examination bed 80. The current heart position of the subject 910 can be understood as its position relative to the examination bed 80. For example, if the distance between the feet of the subject 910 and the foot of the examination bed 80 is H, and the distance between the subject 910's own heart position and its own feet is L, then the distance between the subject 910's own heart position and the foot of the examination bed 80 can be calculated as H+L. That is, the current heart position of the subject 910 is H+L. This application is not limited to the above calculation method; it can also be calculated relative to the headboard, geometric center point, or side of the examination bed 80, as long as the current heart position of the subject 910 can be obtained.

[0051] Therefore, the data processing module 320 can calculate the target position of the object to be inspected 910 based on the image information and the feature information.

[0052] In one embodiment, the specific location of the image acquisition device (not shown in the figure) is not limited. The image acquisition device (not shown in the figure) can be set at any location in the space where the examination bed 80 is located, as long as it can observe the relative position of the object to be inspected 910 and the examination bed 80.

[0053] In one embodiment, the image acquisition device (not shown in the figure) includes a camera, preferably a binocular camera, which is disposed on the wall surface of the space where the examination bed 80 is located, for acquiring image information of the object to be inspected.

[0054] In one embodiment, the data processing module 320 is disposed on the host of the ultrasound diagnostic device 30. The input module 310 is disposed on the host of the ultrasound diagnostic device 30. Both the input module 310 and the data processing module 320 are disposed on the host of the ultrasound diagnostic device 30, thus integrating the input module 310 and the data processing module 320 into one unit.

[0055] In one embodiment, the data processing module 320 is wirelessly connected to the mobile device 10. The data processing module 320 is used to calculate a movement path based on the target location. The mobile device 10 is used to control the signal detection device 20 to move to the target location based on the movement path.

[0056] In this embodiment, the mobile device 10 and the data processing module 320 are wirelessly connected, enabling signal transmission between them. The wireless connection between the data processing module 320 and the mobile device 10 avoids the use of connecting cables, reducing costs and resolving issues caused by cable failures. The data processing module 320 calculates the movement path based on the target location. This movement path is the path the signal detection device 20 needs to take to reach the target location. The data processing module 320 transmits the movement path to the mobile device 10. Simultaneously, the signal detection device 20 is positioned on the mobile device 10. Therefore, the mobile device 10 can move the signal detection device 20 according to the movement path to the target location, thereby detecting the physiological signals of the object to be inspected 910 to obtain physiological signals with less interference and less noise.

[0057] In one embodiment, the data processing module 320 is wirelessly connected to the mobile device 10 and can obtain the current position of the signal detection device 20. The current position of the signal detection device 20 is its location at the current moment, such as being at the foot, head, geometric center, or side of the examination bed 80. At this time, the mobile device 10 transmits the current position of the signal detection device 20 to the data processing module 320. The data processing module 320 calculates the relative distance between the target position and the current position, thus determining the movement path. The data processing module 320 then transmits the movement path to the mobile device 10 to control the signal detection device 20 to move to the target position.

[0058] In one embodiment, the data processing module 320 is wirelessly connected to the signal detection device 20 to acquire the physiological signal and obtain a physiological image of the object to be examined 910 based on the physiological signal.

[0059] In this embodiment, the data processing module 320 and the signal detection device 20 are connected wirelessly, avoiding the use of connecting cables, reducing costs, and solving problems caused by connecting cable failures. When the object to be examined 910 is located on the examination bed 80, the moving device 10 controls the signal detection device 20 to move to the target position and begin detecting the object to be examined 910, acquiring the physiological signals of the object to be examined 910. At this time, the signal detection device 20 transmits the acquired physiological signals to the data processing module 320. The data processing module 320 generates the physiological image of the object to be examined 910 according to the physiological signals. The physiological image includes an electrocardiogram and a phonocardiogram, etc.

[0060] In one embodiment, the electrocardiogram (ECG) signal acquired by the signal detection device 20 is a one-dimensional signal, representing the ECG voltage value at various time points. Simultaneously, the data processing module 320 processes the ECG signal according to the sampling frequency of the signal detection device 20 and according to a set rate and standard voltage, generating a two-dimensional electrocardiogram (i.e., ECG waveform), recording the changes in electrical activity during cardiac depolarization and repolarization.

[0061] In one embodiment, the collected heart sound signals are transmitted to the data processing module 320 via the signal detection device 20. The data processing module 320 processes the heart sound signals according to the sampling frequency of the signal detection device 20 and according to a set rate and standard voltage to generate a two-dimensional phonocardiogram, which records the sound signals generated by the cyclic vibrations of the heart's contraction and diastole.

[0062] In one embodiment, the data processing module 320 can further identify various wavebands (P wave, QRS complex, T wave, etc.) and cardiac axis based on the electrocardiogram to achieve cardiac detection of the subject 910. In addition to processing the physiological signals, the data processing module 320 can also further calculate heart rate, extract heart sound envelope, and identify heart sounds based on the physiological signals.

[0063] In this embodiment, the data processing module 320 calculates heart rate based on an electrocardiogram (ECG): heart rate is the number of heartbeats per minute. In an ECG, one heartbeat generates a P wave, QRS complex, T wave (and U wave, etc.). Therefore, when the heart rhythm is regular, the RR interval (the time interval between two QRS waves) or PP interval (the time interval between two P waves) can be measured to calculate the heart rate. When the heart rhythm is irregular, multiple RR intervals or PP intervals may need to be measured, and their average value taken. Specifically, heart rate (bpm) = 60 / RR interval (seconds) or heart rate (bpm) = 60 / PP interval (seconds).

[0064] The data processing module 320 extracts the envelope and segments based on the phonocardiogram: heart sounds generally include the first heart sound (S1), the second heart sound (S2), the third heart sound (S3, which can only be heard by children and adolescents), and the fourth heart sound (S4, which can be recorded from the phonocardiogram). Based on the phonocardiogram, the data processing module 320 performs preprocessing using wavelet transform, and then extracts the heart sound signal envelope using methods such as mathematical morphology, Hilbert-Huang transform, normalized Shannon energy, and wavelet transform. Then, the data processing module 320 segments the extracted heart sound signal envelope to obtain the first heart sound segment region and the second heart sound segment region.

[0065] Please see Figure 2 In one embodiment, the ultrasound diagnostic device 30 further includes a display module 340. The display module 340 is connected to the data processing module 320 and is used to display the physiological images.

[0066] In this embodiment, the physiological images include an electrocardiogram (ECG) and a phonocardiogram (HCT). The display module 340 can display the ECG and the HCT for presentation to the patient and doctor.

[0067] In one embodiment, the display module 340 is also used to display the ultrasound image.

[0068] In this embodiment, the display module 340 is also used to display the ultrasound image of the patient detected by the probe in the ultrasound diagnostic device 30. Thus, the display module 340 can display ultrasound images, electrocardiograms, and phonocardiograms, providing doctors with auxiliary diagnostic information, thereby improving the efficiency of ultrasound examinations and facilitating the diagnosis of the patient's condition.

[0069] In one embodiment, in addition to displaying ultrasound images and image thumbnails, measurement results, annotation information, and operation menus, the display module 340 can further automatically display physiological signals based on the input examination mode and examination site. For example, when examining the heart-related parts of the subject 910, the display module 340 displays an electrocardiogram (ECG) and a phonocardiogram (HCT). When examining the abdomen, small organs, blood vessels, or other parts of the subject 910 that are not related to the heart, the ECG and HCT are not displayed; only the ultrasound image is displayed.

[0070] In one embodiment, a normal heart rate is between 60 bpm and 100 bpm. When the data processing module 320 determines that the heart rate exceeds the normal range, it notifies the patient of the abnormal condition through the display module 340 (e.g., by popping up a warning window) and alerts the doctor, providing auxiliary diagnostic information.

[0071] In one embodiment, the display module 340 is a display screen used to display electrocardiograms, phonocardiograms, ultrasound images and image thumbnails, measurement results, annotation information, operation menus, etc.

[0072] Please see Figure 2 In one embodiment, the ultrasound diagnostic device 100 with physiological signal detection function further includes a first wireless transmission module 40. The first wireless transmission module 40 is disposed on the examination bed 80. The ultrasound diagnostic device 30 further includes a second wireless transmission module 330. The first wireless transmission module 40 and the second wireless transmission module 330 are wirelessly connected to enable wireless communication between the mobile device 10, the signal detection device 20, the image acquisition device, and the data processing module 320, respectively.

[0073] In this embodiment, the signal detection device 20, the mobile device 10, and the image acquisition device can share the first wireless transmission module 40 to achieve wireless communication connections with the data processing module 320. This can be understood as follows: the signal detection device 20 and the data processing module 320 are wirelessly connected via the first wireless transmission module 40 and the second wireless transmission module 330. The mobile device 10 and the data processing module 320 are wirelessly connected via the first wireless transmission module 40 and the second wireless transmission module 330. The image acquisition device and the data processing module 320 are wirelessly connected via the first wireless transmission module 40 and the second wireless transmission module 330. Therefore, signals, such as physiological signals and the current location information of the signal detection device 20, can be transmitted to each other via the first wireless transmission module 40 and the second wireless transmission module 330. For example, the second wireless transmission module 330 sends the current location information of the signal detection device 20, and the first wireless transmission module 40 receives the current location information. The first wireless transmission module 40 sends the physiological signal, the second wireless transmission module 330 receives the physiological signal, and transmits it to the data processing module 320.

[0074] Please see Figure 3 In one embodiment, the moving device 10 includes two mutually perpendicular movable guide rails 110. The two movable guide rails 110 are disposed below the examination bed 80. The signal detection device 20 is disposed at the intersection of the two movable guide rails 110.

[0075] In this embodiment, the two movable guide rails 110 are arranged intersecting, which can be understood as the two movable guide rails 110 intersecting at a certain angle. The signal detection device 20 is disposed at the intersection of the two movable guide rails 110. When the two movable guide rails 110 slide relative to each other, they can drive the signal detection device 20 to move. The two movable guide rails 110 can be two screws, both disposed on the same plane and respectively along the direction of the examination bed 80 and perpendicular to the direction of the examination bed 80. The two movable guide rails 110 allow the signal detection device 20 to be moved to the target position within a plane parallel to the examination bed 80. Thus, the moving device 10 can move the position of the signal detection device 20 according to the movement path and move it to the target position, thereby detecting the physiological signals of the object to be examined 910 to obtain physiological signals with less interference and less noise.

[0076] In one embodiment, the movable guide rail 110 can be a ball screw, which can convert rotary motion into linear motion, or linear motion into rotary motion. Ball screws have advantages such as low friction loss, high transmission efficiency, high precision, and high axial stiffness, enabling high-speed and micro-feeding.

[0077] In one embodiment, the two ends of the two movable guide rails 110 are respectively connected to the examination bed 80 via sliders, and sliders are provided at the intersection of the two movable guide rails 110. The signal detection device 20 is mounted on the sliders. The sliders are driven by a motor, which can drive the sliders at both ends of the movable guide rails 110 and also drive the slider connected to the signal detection device 20, thereby enabling the signal detection device 20 to move in a plane parallel to the examination bed 80 and be adjusted to the target position.

[0078] In one embodiment, the signal detection device 20 is positioned close to the object to be inspected 910.

[0079] In this embodiment, the signal detection device 20 is mounted on the sliders of the two movable guide rails 110 and is positioned close to the object to be inspected 910 to facilitate the acquisition of the physiological signals of the object to be inspected 910.

[0080] In one embodiment, two movable guide rails 110 are disposed inside the examination bed 80. In this case, the examination bed 80 has a hollow structure, and the two movable guide rails 110, the signal detection device 20, and the first wireless transmission module 40 are all disposed inside the hollow structure and close to the object to be examined 910 to facilitate the acquisition of the physiological signals.

[0081] In one embodiment, when the data processing module 320 calculates the movement path based on the target position and the current position, it establishes a coordinate system with the center point of the plane where the two movable guide rails 110 are located as the origin, and calculates the movement path that should be moved between the target position (heart position) and the current position (current position of the signal detection device 20).

[0082] In the above embodiments, the signal detection device 20, the input module 310, the data processing module 320, the display module 340, the first wireless transmission module 40, and the second wireless transmission module 330 include, but are not limited to, microcontroller units (MCUs), central processing units (CPUs), embedded microcontroller units (MCUs), embedded microprocessors (MPUs), and embedded systems on chips (SOCs).

[0083] Furthermore, the mobile device 10, the signal detection device 20, the input module 310, the data processing module 320, the display module 340, the first wireless transmission module 40, and the second wireless transmission module 330 in the ultrasound diagnostic device 100 with physiological signal detection function can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device in hardware form, or stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module. It should be noted that the module division in this embodiment is illustrative and only represents a logical functional division; in actual implementation, there may be other division methods.
