Description

Technical Field

[0001] The present application relates to the field of medical electronic technology, and in particular to a simulator control method and related devices. Background Art

[0002] Blood pressure is the pressure exerted on the blood vessel wall by the blood flow impulse when blood flows through the blood vessels, that is, pressure. Blood pressure is one of the most important vital signs of the human body and an important basis for disease diagnosis, treatment effect evaluation, and vital sign evaluation. Hypertension is one of the most certain and important risk factors for cardiovascular and cerebrovascular diseases. The prevalence of hypertension in China exceeds 300 million people. Therefore, blood pressure testing is one of the most important parameters in clinical diagnosis and family health management. At the same time, with the acceleration of the global aging process and the increase in the incidence of chronic diseases, the accuracy, popularity, and household use of blood pressure testing equipment have become rigid demands.

[0003] At present, the "gold standard" for blood pressure measurement widely used in the medical industry is the Korotkoff sound method. The measurement process is to block the blood flow in the artery with a cuff, then slowly deflate it, and listen to the Korotkoff sounds with a stethoscope. At first, you can hear strong Korotkoff sounds, which then gradually become lighter until they disappear. The high pressure corresponding to the reading of the mercury sphygmomanometer when you hear the Korotkoff sound for the first time is the systolic pressure; continue to deflate, and the last Korotkoff sound corresponds to the diastolic pressure.

[0004] In order to improve the convenience of blood pressure detection, electronic blood pressure monitors have become popular. However, electronic blood pressure monitors also have certain disadvantages in actual applications. That is, as the number of uses of the electronic blood pressure monitor increases, its detection accuracy may begin to decrease, resulting in deviations in the actual measured blood pressure values. Therefore, there is an urgent need for a technology that can realize the detection accuracy analysis of electronic blood pressure monitors. Summary of the invention

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.

[0029] In order to solve the problem that the accuracy of blood pressure detection cannot be guaranteed due to the lack of detection accuracy analysis means in the electronic sphygmomanometer in the related art, the first embodiment of the present application provides a simulator control method, which is applied to the simulator. The simulator includes an air pressure generating component and a Korotkoff sound generating component. The air supply pipe of the air pressure generating component is used to connect the cuff cannula of the electronic sphygmomanometer to be tested. The Korotkoff sound generating component is provided with a sensor placement position, and the sensor placement position is used to place the Korotkoff sound sensor of the electronic sphygmomanometer to be tested. It should be noted that in actual applications, the sensor placement position can be a physical component, such as a tray, etc., for contacting the Korotkoff sound sensor thereon. In another implementation, the sensor placement position can also be a certain characteristic area on the Korotkoff sound generating component. When the Korotkoff sound sensor of the electronic sphygmomanometer to be tested is in a non-contact state relative to the characteristic area, the Korotkoff sound output by the Korotkoff sound generating component can be effectively collected.

[0030] It should be understood that the electronic blood pressure monitor to be tested can be composed of a cuff, a Korotkoff sound sensor, an air pressure sensor, a processing unit, a pressure control unit, a human-computer interaction unit, etc. The cuff is provided with a cuff airbag, and the cannula of the cuff airbag is connected to the air pressure generating component of the simulator. The Korotkoff sound sensor can be a sound vibration digital sensor based on piezoelectric film, a sound sensing MEMS chip, an electret microphone, etc., which is placed in the Korotkoff sound generating component of the simulator to collect the Korotkoff sounds output by the Korotkoff sound generating component, and the Korotkoff sound detection algorithm is run by the processing unit to process the collected signals, and the sounds of the start and end of the Korotkoff sounds are accurately obtained to detect the blood pressure measurement data.

[0031] like Figure 1 This is a basic flow chart of the simulator control method provided in this embodiment. The simulator control method includes the following steps:

[0032] Step 101: When the air pressure generating component is in a pressurized state, control the air pressure generating component to decompress.

[0033] Specifically, the air pressure generating component of this embodiment is first pressurized and inflated to a target pressure, and then begins to decompress, simulating the deflation process of an electronic sphygmomanometer to construct a simulated blood pressure detection scenario.

[0034] In an optional implementation of the present embodiment, before the above-mentioned step of controlling the air pressure generating component to reduce pressure, it also includes: obtaining user characteristic information of the user of the electronic blood pressure monitor to be tested; wherein the user characteristic information includes at least one of the following: gender, age, and medical history; determining corresponding simulator control parameters based on the user characteristic information; wherein the simulator control parameters include at least one of the following: a first control parameter of the air pressure generating component (used to perform decompression control on the air pressure generating component), a pressure threshold, and a second control parameter of the Korotkoff sound generating component (used to perform Korotkoff sound simulation control on the Korotkoff sound generating component).

[0035] Specifically, the medical history of this embodiment includes severe anemia, hyperthyroidism, aortic valve insufficiency, etc. This embodiment can divide users into children, young people, and the elderly according to their age groups. In this embodiment, considering that the physiological states of different user groups are different, simulating a general blood pressure detection scenario may result in poor detection accuracy. Based on this, this embodiment can configure a variety of different simulator execution scripts for different user groups, and then call the corresponding simulator execution script according to the user feature information in actual applications to control the relevant components of the simulator to work according to the corresponding parameters, so as to ensure the accuracy and flexibility of pressure control and Korotkoff sound output.

[0036] In an optional implementation manner of the present embodiment, the step of controlling the air pressure generating component to reduce pressure includes: controlling the air pressure generating component to reduce pressure according to corresponding gas flow rates in the first decompression stage, the second decompression stage and the third decompression stage; wherein the first decompression stage is from the start time of decompression to the time when the pressure value reaches the systolic pressure reference threshold, the second decompression stage is from the time when the pressure value reaches the systolic pressure reference threshold to the time when the pressure value reaches the diastolic pressure reference threshold, and the third decompression stage includes the time after the pressure value reaches the diastolic pressure reference threshold; the gas flow rate in the first decompression stage is greater than the gas flow rate in the second decompression stage, and the gas flow rate in the third decompression stage is greater than the gas flow rate in the first decompression stage.

[0037] Specifically, in the traditional blood pressure detection scheme, after the sphygmomanometer is pressurized to the maximum pressure, a constant gas flow rate is used to reduce the pressure until the last Korotkoff sound is detected, and then the gas flow rate is increased to reduce the pressure until the pressure is completely reduced. Figure 2 The figure shows a schematic diagram of pressure control provided by the present embodiment. The section A to B is the pressurization stage. The present embodiment starts rapid decompression in the first decompression stage, i.e., the section B to C. After the first Kostiel sound output condition is met at point C, the decompression speed is slowed down in the second decompression stage, i.e., the section C to D, so that the signal quality collected in this stage is higher. Moreover, when the decompression speed is slowed down, the pressure change simulated for each heartbeat interval becomes smaller, and the measurement accuracy is higher. Next, after the last Kostiel sound is detected at point D, the decompression is rapidly carried out at the maximum decompression speed in the third decompression stage, i.e., the section D to E.

[0038] Step 102: During the decompression process of the air pressure generating component, obtain the real-time pressure value.

[0039] Step 103: Compare the real-time pressure value with the preset pressure threshold.

[0040] Specifically, the pressure threshold of this embodiment may include a systolic pressure reference threshold, a diastolic pressure reference threshold, and further, an intermediate pressure threshold, that is, a plurality of pressure thresholds corresponding to Korotkoff sounds 2 to 4. In this embodiment, the real-time pressure value is compared with the characteristic pressure value to determine whether the Korotkoff sound output condition is currently met.

[0041] Step 104: When the real-time pressure value matches the pressure threshold, control the Korotkoff sound generating component to output a corresponding type of simulated Korotkoff sound.

[0042] Specifically, in this embodiment, corresponding pressure thresholds are set for Korotkoff sounds of different phases. When the real-time pressure of the simulator reaches a specific pressure threshold, the Korotkoff sounds corresponding to the pressure threshold are output for perception by the Korotkoff sound sensor of the electronic blood pressure monitor to be tested that is in close contact with the Korotkoff sound generating component.

[0043] In an optional implementation of the present embodiment, the Korotkoff sound generating component includes a digital-to-analog conversion unit; the step of controlling the Korotkoff sound generating component to output a corresponding type of simulated Korotkoff sound includes: determining a corresponding Korotkoff sound audio file according to a pressure threshold; controlling the digital-to-analog conversion unit of the Korotkoff sound generating component to perform digital-to-analog conversion on the Korotkoff sound audio file and output simulated Korotkoff sound.

[0044] Specifically, the simulator of this embodiment is pre-set with different Korotkoff sound audio files. In actual application, the digitized Korotkoff sound audio file can be determined according to the characteristic pressure threshold, and then the digital-to-analog conversion unit converts the audio file into a Korotkoff sound analog signal for external output.

[0045] like Figure 3 The figure shows a schematic diagram of the structure of a Korotkoff sound generating assembly provided in the present embodiment. In an optional implementation manner of the present embodiment, the Korotkoff sound generating assembly includes an electric piston 31, a liquid accommodating chamber 32, an elastic fluid pipeline 33, a one-way valve 34, and a sensor placement position 35. The electric piston 31 cooperates with the liquid accommodating chamber 32, the elastic fluid pipeline 33 is connected to the liquid accommodating chamber 32, the one-way valve 34 is arranged in the elastic fluid pipeline 33, the number of the one-way valves 34 can be two, which are used to control the direction of liquid flow, the elastic fluid pipeline 33 can include two sub-elastic fluid pipelines connected by a connecting pipeline 36 (such as a hose), the sensor placement position 35 is arranged opposite to the connecting pipeline 36, and the sensor placement position 35 is preferably implemented by a tray.

[0046] Correspondingly, the above-mentioned step of controlling the Korotkoff sound generating component to output the corresponding type of simulated Korotkoff sound includes: determining the corresponding piston control parameters according to the pressure threshold; wherein the piston control parameters include the piston reciprocating frequency and the piston reciprocating amplitude; controlling the electric piston movement of the Korotkoff sound generating component according to the piston control parameters, and generating simulated Korotkoff sound by driving the liquid in the liquid containing chamber to flow in the elastic fluid pipe.

[0047] Specifically, the electric piston of the present embodiment may be composed of a piston and a piston driver, and the reciprocating motion of the piston simulates heart fluctuations, thereby pushing the liquid to flow in the fluid pipeline, and simulating the fluid pipeline into a blood vessel. In the present embodiment, for different Korotkoff sounds, the corresponding piston control parameters are adaptively used to control the piston movement, and the amplitude and frequency of the reciprocating motion of the piston are controlled to simulate different states of pipeline pulsation during blood flow, thereby simulating the generation of Korotkoff sounds 1 to 5. For example, when simulating the first Korotkoff sound, the reciprocating frequency is 60 times / minute, and the flow rate ejected in one reciprocating motion is 60mL. When simulating the fourth Korotkoff sound, the reciprocating frequency is 100 times / minute, and the flow rate ejected in one reciprocating motion is a maximum of 80mL. When simulating the fifth Korotkoff sound, the piston gradually stops moving.

[0048] In an optional implementation of the present embodiment, when the pressure threshold is the systolic pressure reference threshold, after the above-mentioned step of controlling the Korotkoff sound generating component to output the corresponding type of simulated Korotkoff sound, it also includes: controlling the air pressure generating component to stop decompression; and when the preset delay time is reached, continuing to trigger the air pressure generating component to decompress.

[0049] Specifically, in this embodiment, when the air pressure of the simulator reaches the preset systolic pressure reference threshold, the air pressure generating component can be temporarily controlled to suspend deflation and decompression according to a certain delay time, so that after the Korotkoff sound generating module outputs the first Korotkoff sound, the electronic blood pressure monitor to be tested has sufficient time to collect systolic pressure data, and after the delay time is reached, the air pressure generating component can continue to be controlled to deflate and decompress, so as to continue to simulate subsequent blood pressure detection scenarios.

[0050] It should be noted that, in the present embodiment, when it is detected that the real-time pressure value meets the pressure threshold corresponding to the second to fourth Korotkoff sounds, the Korotkoff sounds playback duration can be calculated based on the gas flow rate during decompression, and then the Korotkoff sounds generating component can be controlled to output Korotkoff sounds corresponding to the Korotkoff sounds playback duration to control the speed of the second to fourth Korotkoff sounds.

[0051] In an optional implementation of the present embodiment, after the above-mentioned step of controlling the Korotkoff sound generating component to output the corresponding type of simulated Korotkoff sounds, it also includes: obtaining blood pressure measurement data of the electronic blood pressure meter to be tested; comparing the blood pressure measurement data with the pressure threshold; and outputting the detection accuracy analysis result of the electronic blood pressure meter to be tested based on the comparison result.

[0052] Specifically, in actual applications, after the simulator of this embodiment outputs Korotkoff sounds, the electronic sphygmomanometer to be tested will measure blood pressure based on the simulated Korotkoff sounds to obtain blood pressure measurement data. In one implementation, a specialist can manually compare the blood pressure data of the simulator and the electronic sphygmomanometer to analyze the detection accuracy of the electronic sphygmomanometer. In order to improve the convenience and accuracy of the detection accuracy analysis, this embodiment can allow the electronic sphygmomanometer to interact with the simulator, report the blood pressure measurement data of the electronic sphygmomanometer to the simulator, and then the simulator compares the blood pressure measurement data with its own characteristic pressure threshold, thereby automatically outputting the detection accuracy of the electronic sphygmomanometer. Furthermore, when the detection accuracy of the electronic sphygmomanometer does not meet the standard detection requirement indicators, the corresponding sphygmomanometer calibration parameters can be generated based on the detection accuracy deviation value, and then sent to the electronic sphygmomanometer, which will automatically calibrate according to the sphygmomanometer calibration parameters to ensure the effectiveness of the use of the electronic sphygmomanometer.

[0053] Based on the technical solution of the embodiment of the present application, when the air pressure generating component is in the pressurized state, the air pressure generating component is controlled to decompress; during the decompression process of the air pressure generating component, a real-time pressure value is obtained; the real-time pressure value is compared with a preset pressure threshold; wherein the pressure threshold includes a systolic pressure reference threshold and a diastolic pressure reference threshold; when the real-time pressure value matches the pressure threshold, the Korotkoff sound generating component is controlled to output a corresponding type of simulated Korotkoff sound. Through the implementation of the solution of the present application, a simulator is used to simulate the inflation and deflation process and the Korotkoff sound output process during blood pressure detection to assist in detecting the Korotkoff sound recognition accuracy of the sphygmomanometer, effectively realizing the detection accuracy analysis of the electronic sphygmomanometer and ensuring the blood pressure detection accuracy of the electronic sphygmomanometer.
