Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
In human body, peripheral arteries including the middle and small arteries of limbs and trunk except heart and brain are important components of arterial circulation system, and the large arteries branch from heart to periphery, and the calibers of blood vessels increase gradually from large to small, and if the branches spread over the whole body, a huge blood vessel network is formed. The peripheral arterial blood vessels can undergo irreversible degeneration with the age, including thickening, hardening, losing elasticity, narrow and small lumens and obstructed blood flow, so that the hemodynamics is obviously changed, local perfusion deficiency, remote ischemia and the like are caused, thereby causing peripheral arterial diseases, clinical manifestations such as lower limb intermittent claudication and the like, vessel occlusion of serious patients, blood circulation obstruction, gangrene and amputation.
Since the hemodynamic changes earlier than the clinical symptoms appear in cardiovascular diseases, especially peripheral arterial diseases, the noninvasive monitoring of peripheral arterial hemodynamics has higher clinical practical value for rapid screening and early diagnosis of peripheral arterial diseases, can obviously improve the detection rate of peripheral arterial diseases when used for routine examination, and is particularly significant for identifying asymptomatic patients.
Therefore, color doppler ultrasound has been widely used in clinical applications for monitoring peripheral arterial hemodynamics, and its basic principle is: firstly, an ultrasonic wave is generated by an ultrasonic transducer transmitting end through an inverse piezoelectric effect under the action of high-frequency voltage, then the ultrasonic wave is scattered when entering a human blood vessel and encountering a scatterer (mainly red blood cell) moving in blood, the red blood cell becomes a new sound source, and finally, a transducer receiving end receives scattered echo and converts the ultrasonic wave into a high-frequency voltage signal through a positive piezoelectric effect. According to the Doppler effect principle, there is a difference between the frequency of the received acoustic signal and the frequency of the transmitted signal, called the Doppler shift fdAnd is and
wherein f isdDoppler shift for blood flow signals; v is the mean velocity of blood flow; c is the average propagation speed of the ultrasonic waves in the human soft tissue; f. of0Transmitting the frequency of an ultrasonic signal for a transducerRate; theta is an included angle between the ultrasonic probe and the blood flow direction; by + -is meant the direction of blood flow. Therefore, the detection precision of the blood flow speed can be influenced by the included angle between the ultrasonic probe and the blood flow direction.
Based on this, this application embodiment provides an ultrasonic diagnostic equipment, and this ultrasonic diagnostic equipment can combine a plurality of gesture information that the gesture measuring unit detected, confirms the measurement gesture of a preferred, promptly under this measurement gesture, the contained angle of ultrasonic probe and blood flow direction is the detection contained angle of preferred, when carrying out blood flow speed detection, then compares in prior art, can obtain more accurate blood flow speed.
To facilitate understanding of the present application, a description will be given of an application scenario to which the present application may be applied, and referring to fig. 2, fig. 2 is an exemplary ultrasound diagnostic apparatus for detecting blood flow velocity according to an embodiment of the present invention, and the ultrasound diagnostic apparatus may be in any suitable product form, for example, the ultrasound diagnostic apparatus may be a cylindrical structure with a detection function, and meanwhile, the ultrasound diagnostic apparatus may also be disposed in a household apparatus or a medical apparatus for detecting blood flow velocity, for example, fig. 2 exemplarily shows an embodiment in which the ultrasound diagnostic apparatus 100 is disposed on a massage chair.
In concrete implementation, please refer to fig. 3 together, when a user places a hand on the ultrasonic diagnostic apparatus 100, the ultrasonic probe 10 inside the ultrasonic diagnostic apparatus 100 starts to start detection, at this time, the piezoelectric ceramic 11 in the ultrasonic probe 10 can send out an ultrasonic signal, when the ultrasonic signal hits an obstacle (i.e. a part to be detected through which blood flows of the user) in the air in the process of propagation, the ultrasonic signal returns immediately and generates an echo signal, the echo signal is received by the piezoelectric ceramic 11, the piezoelectric ceramic 11 can generate an echo electric signal, and the blood flow velocity can be obtained by analyzing the echo electric signal; meanwhile, the posture measuring unit 30 in the ultrasonic probe 10 can detect the posture information of the ultrasonic probe 10 at the time point in real time, that is, the posture information corresponding to the echo electric signal or the blood flow velocity.
By changing the relative angle between the part to be detected of the user and the ultrasonic probe 10, for example, by rotating the ultrasonic probe 10 by one turn relative to the part to be detected of the user, echo electrical signals or blood flow velocity in different postures can be obtained. Therefore, the ultrasonic diagnostic apparatus 100 may determine a better reference measurement posture according to the obtained echo electrical signal or blood flow velocity in different postures and the posture information corresponding thereto, for example, after the ultrasonic probe 10 rotates one turn, extract the time at which the echo electrical signal is strongest in the rotation process, and then correspondingly find the posture of the ultrasonic probe 10 at the time, so that the posture is a better reference measurement posture.
Then, if the relative angle between the part to be detected of the user and the ultrasonic probe 10 is changed again, in the process of adjusting the ultrasonic probe 10, when the detected current posture information is in the range corresponding to the reference measurement posture, the user can be prompted to fixedly keep the current posture so as to perform detection under the current posture, then, the ultrasonic diagnostic device 100 can also feed back the diagnostic result to the user, for example, the diagnostic result can be uploaded to the cloud through a WiFi module, and the user can use the APP on the mobile phone to check the relevant information of the blood flow speed.
In other embodiments, the ultrasonic diagnostic apparatus 100 may also exist in other product forms, such as a belt-like structure having a blood flow velocity detection function. Of course, the ultrasonic diagnostic apparatus 100 may be present in a separate product form without being attached to the belt-like structure, in which case it is simply placed on the portion to be detected of the human body when it is used to detect the blood flow velocity of the human body.
As shown in fig. 4, the ultrasonic diagnostic apparatus 100 includes an ultrasonic probe 10, a control unit 20, an attitude measurement unit 30, and a signal processing unit 40, wherein the attitude measurement unit 3 is provided inside the ultrasonic probe 10, and the control unit 20 is connected to the ultrasonic probe 10, the attitude measurement unit 30, and the signal processing unit 40, respectively.
Specifically, the ultrasonic probe 10 is configured to generate an ultrasonic signal or receive an ultrasonic echo signal and generate an echo electric signal, the signal processing unit 40 is configured to output a signal containing blood flow information based on the echo electric signal, the posture measuring unit 30 is configured to detect posture information of the ultrasonic probe 10, and the control unit 20 is configured to determine a blood flow velocity based on the signal containing blood flow information and determine a reference measurement posture based on the posture information.
In practical application, the control unit 20 first outputs a control signal to control the ultrasonic probe 10 and transmit ultrasonic waves at a preset frequency, the ultrasonic waves form echo signals after encountering an obstacle (i.e., a detected part of a user), the ultrasonic echo signals are received by the ultrasonic probe 10, fluctuations received by the ultrasonic probe 10 are converted into echo electric signals and transmitted to the signal processing unit 40, the signal processing unit 40 processes the echo signals to obtain signals containing blood flow information and transmits the signals to the control unit 20, and the control unit 20 analyzes and processes the signals containing the blood flow information to determine the blood flow velocity.
Meanwhile, the attitude measurement unit 30 is a high-performance three-dimensional motion attitude measurement system based on the MEMS technology, and includes motion sensors such as a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass, and obtains data such as a three-dimensional attitude and an orientation subjected to temperature compensation by an embedded low-power ARM processor, and outputs zero-drift three-dimensional attitude orientation data expressed by a quaternion and an euler angle in real time by using a quaternion-based three-dimensional algorithm and a special data fusion technology. Therefore, the posture measuring unit 30 can detect the three-dimensional posture position information of the ultrasonic probe 10 in real time and also transmit the three-dimensional posture position information to the control unit 20, so that the control unit 20 can select a reference measurement posture, and under the reference measurement posture, the blood flow velocity of the part to be measured of the user at the moment can be determined, and more accurate data can be obtained.
Moreover, since the ultrasonic diagnostic apparatus 100 provided in this embodiment can automatically or manually adjust to a preferred reference measurement posture according to the data detected by the posture measurement unit 30, it is also very convenient for non-professionals to use the ultrasonic diagnostic apparatus 100 to detect the blood flow velocity, and the accuracy of the detected data is high, which is beneficial to the popularization and use of the ultrasonic diagnostic apparatus 100 in a home scene.
Alternatively, as shown in fig. 5, the signal processing unit 40 includes a signal demodulation circuit 41 and a filtering and amplifying circuit 42, and the filtering and amplifying circuit 42 is connected to the signal demodulation circuit 41 and the control unit 20, respectively.
Specifically, the signal demodulation circuit 41 is configured to demodulate an echo signal of the ultrasonic signal to obtain a signal containing blood flow information, and the filtering and amplifying circuit 42 is configured to amplify and filter the signal containing blood flow information and transmit the signal to the control unit 20.
In an embodiment, the signal demodulation circuit 41 may use the multiplication circuit chip MC1596 to implement multiplication demodulation, that is, the signal demodulation circuit can demodulate the echo signal of the ultrasonic wave received by the ultrasonic probe 10, so as to obtain a doppler shift signal containing the blood flow velocity.
The filtering and amplifying circuit 42 amplifies and filters the demodulated signal, and selects a 0-2000HZ filtering frequency passband to perform filtering, thereby improving the signal-to-noise ratio of the signal. Illustratively, the filtering and amplifying circuit 42 is formed by selecting three comparators, wherein the comparator U1 is formed into a gain adjustable circuit 421, and the gain adjustable circuit 421 is used for performing amplification processing on a signal containing blood flow information; the comparator U2 and the comparator U3 form a second-order low-pass filter circuit 422, and the second-order low-pass filter circuit 422 is configured to filter the amplified signal containing the blood flow information.
Referring to fig. 6 IN conjunction with fig. 5, the comparator U1 constitutes the GAIN adjustable circuit 421, the demodulated signal, i.e., the signal containing blood flow information, is input from the unidirectional input terminal of the comparator U1 through the connection IN1, and the input signal of the inverting input terminal of the comparator U1 is determined by the MOS transistor Q2 and the MOS transistor Q3, so that the on and off of the MOS transistor Q2 and the MOS transistor Q3 are controlled by the different signals input through the port GAIN1 and the port GAIN2, so that the GAIN of the signal at the output terminal of the comparator U1 can be adjusted, and therefore, the phenomenon that the amplitude of the signal at the output terminal of the comparator U1 is too small or too large to affect the diagnostic result, for example, the phenomenon that the amplitude of the signal at the output terminal of the comparator U1 is too large to cause the top clipping distortion, can be avoided. The comparator U2 and the comparator U3 form a second-order low-pass filter circuit 422, the second-order low-pass filter circuit 422 with a cut-off frequency of 2000HZ filters the signal after gain adjustment to obtain a signal containing blood flow information, then the control unit 20 can perform AD sampling on the demodulated echo signal, the sampling frequency can be set to 4KHz, and the sampled data is subjected to algorithm processing to calculate blood flow dynamics parameters such as blood flow velocity.
In another embodiment, referring to fig. 5 again, the ultrasonic diagnostic apparatus 100 further includes a signal excitation unit 50, the signal excitation unit 50 is respectively connected to the ultrasonic probe 10 and the control unit 20, and the signal excitation unit 50 is configured to output an excitation signal based on a control signal of the control unit 20, so that the ultrasonic probe 10 generates an ultrasonic signal.
For example, referring to fig. 7 in conjunction with fig. 5, the signal excitation unit 50 is turned on and off through the MOS transistor Q1 to generate an excitation signal to the piezoelectric ceramic T1 in the ultrasound probe 10.
A control signal output end of the control unit 20 is connected to one end of a first capacitor C1 through an input end I1, the other end of a first capacitor C1 is connected to a gate of a MOS transistor Q1, an anode of a first diode D1 is connected to a gate of a MOS transistor Q1, a cathode of a first diode D1 is connected to a source of the MOS transistor Q1 and a working power supply V1, a first resistor R1 is connected in parallel to the first diode D1, a second capacitor C2 is connected in parallel to a third capacitor C3, one end of a second capacitor C2 is connected to the working power supply V1, the other end of the second capacitor is grounded, a drain of the MOS transistor Q1 is connected to one end of a piezoelectric ceramic T1, and the other end of the piezoelectric ceramic T1 is grounded.
Specifically, the first capacitor C1 is used for filtering out the tip pulse in the control signal; the first resistor R1 can make a voltage difference between the gate and the source of the MOS transistor Q1, thereby realizing the conduction of the MOS transistor Q1; the first diode D1 is used to prevent the breakdown between the gate and the source of the MOS transistor Q1 due to the excessive voltage, and thus, the MOS transistor Q1 is protected; due to the characteristics of the capacitors of the ac-dc resistance, the second capacitor C2 and the third capacitor C3 are both used for passing the ac power of the working power supply V1, and therefore the current flowing to the MOS transistor Q1 is the dc current in the working power supply V1.
In practical application, the control unit 20 outputs a control signal to the gate of the MOS transistor Q1 through the input terminal I1, the MOS transistor Q1 is a P-channel MOS transistor, and when the control signal is at a high level, the current voltage value Vgs of the gate-source electrode of the MOS transistor Q1 is greater than the turn-on voltage value Vgs (th) of the gate-source electrode of the MOS transistor Q1, and the MOS transistor Q1 is in a cut-off state; conversely, when the excitation signal is low, Vgs < Vgs (th), the MOS transistor Q1 is turned on. When the control signal is a low-level signal, the MOS transistor Q1 is turned on, the operating power supply V1 is connected to the piezoelectric ceramic T1 through the source and the drain of the MOS transistor Q1, so that the piezoelectric ceramic T1 has an electrical signal input, the piezoelectric ceramic T1 can generate an ultrasonic wave, otherwise, when the control signal is a high-level signal, the MOS transistor Q1 is turned off, the connection between the operating power supply V1 and the piezoelectric ceramic T1 is broken, the piezoelectric ceramic T1 cannot generate an ultrasonic wave signal, and the frequency of the ultrasonic wave signal generated by the piezoelectric ceramic T1 corresponds to the frequency of the control signal.
In one embodiment, referring to fig. 5 again, the ultrasonic diagnostic apparatus 100 further includes a voice unit 60a, the voice unit 60a is connected to the control unit 20, and the voice unit 60a is configured to output corresponding voice information based on an output instruction of the control unit 20.
For example, when the current posture information matches the determined optimal detection posture, the voice unit 60a outputs an instruction as a posture confirmation instruction to prompt the user to keep the current posture for detection; when the current posture information does not match the determined optimum detection posture, the voice unit 60a outputs an instruction as a posture adjustment instruction for prompting the user to adjust the angle between the ultrasonic probe 10 and the detected part of the user.
Further, an automatic adjustment mode may be set, for example, a motor lifting device connected to the ultrasound probe 10 is provided, when the ultrasound probe 10 needs to perform posture adjustment, the posture of the ultrasound probe 10 may be adjusted by driving the motor lifting device, and when the posture information matches the determined optimal detection posture, the driving of the motor lifting device is stopped, so that the ultrasound probe 10 maintains the current posture for detection.
Optionally, the ultrasonic diagnostic apparatus 100 further includes an LED unit 60b, the LED unit 60b is connected to the control unit 20, and the LED unit 60b is configured to output a corresponding light prompt based on an output instruction of the control unit 20.
For example, when the current posture information matches the determined optimum detection posture, and the output command is a posture confirmation command at this time, the LED unit 60b becomes a normally on state according to the posture confirmation command of the control unit 20 to prompt the user to keep the current posture for detection; when the current posture information does not match the determined optimal detection posture, the LED unit 60b is in a normally off state, and at this time, the user needs to continuously adjust the angle between the ultrasonic probe 10 and the detected part of the user until the LED unit 60b is turned on. Also, an auto-adjusting mode may be set, and the control process is similar to that when the voice unit 60a is used, which is within the scope easily understood by those skilled in the art and will not be described herein.
