For ease of understanding, fig. 3 shows a schematic calibration flow chart of a sphygmomanometer calibration apparatus, and specifically, as shown in fig. 3, includes the following flows S1 to S6:
s1, after a trigger signal of the gas sensing unit 11 connected with the sphygmomanometer to be calibrated is monitored, initial feedback sent by the sphygmomanometer to be calibrated is obtained.
Specifically, the gas sensing unit 11 is first connected to the sphygmomanometer to be calibrated, and when the connection between the gas sensing unit 11 and the sphygmomanometer to be calibrated is successful, the control unit 10 issues a calibration command to the sphygmomanometer to be calibrated and waits for the initial feedback of the sphygmomanometer to be calibrated.
In a specific implementation, the sphygmomanometer calibration apparatus may include a communication unit connected to the control unit 10; that is, the sphygmomanometer calibration apparatus may be in communication connection with a sphygmomanometer to be calibrated, which has a communication function, and at this time, the control unit 10 is further configured to be in communication connection with the sphygmomanometer to be calibrated through the communication unit, and confirm that the trigger signal is monitored after the connection is successful.
Specifically, after the gas sensing unit 11 is connected to the sphygmomanometer to be calibrated with the communication function through an external gas circuit, the sphygmomanometer calibration device starts a communication mode of the sphygmomanometer to be calibrated, starts an identification protocol after identifying the name of the sphygmomanometer to be calibrated, and sends a calibration instruction to the sphygmomanometer to be calibrated to wait.
Further, the communication unit comprises at least one of the following modules: the WIFI communication module, the Bluetooth communication module and the mobile communication module; the WIFI communication module is used for being in communication connection with the sphygmomanometer to be calibrated, which comprises WIFI communication signals; the Bluetooth communication module is used for being in communication connection with the sphygmomanometer to be calibrated, which comprises a Bluetooth communication signal; the mobile communication module is used for being in communication connection with the sphygmomanometer to be calibrated, which comprises mobile communication signals.
Further, the sphygmomanometer to be calibrated may also be a sphygmomanometer without a communication function, that is, the sphygmomanometer calibration apparatus may also not include the communication unit for use, and at this time, the sphygmomanometer calibration apparatus may calibrate the sphygmomanometer to be calibrated without a communication function. In a specific implementation, after the gas sensing unit 11 is connected to the sphygmomanometer to be calibrated through the external gas path, the sphygmomanometer to be calibrated is directly defaulted to be connected to the sphygmomanometer calibration device.
Further, the sphygmomanometer calibration apparatus further includes a mode selection unit connected to the control unit 10; the mode selection unit is configured to send a preset mode selection instruction to the control unit 10, so that the control unit 10 calibrates the sphygmomanometer to be calibrated according to a preset calibration mode.
Specifically, the mode selection unit may correspond to a key, and in a specific implementation, the key may be triggered to send a calibration instruction to the sphygmomanometer without a communication function to be calibrated, and wait for an initial feedback of the sphygmomanometer to be calibrated.
Further, while the control unit 10 waits for the initial feedback, the sphygmomanometer to be calibrated performs the following operations:
(1) And after receiving the calibration instruction, the sphygmomanometer to be calibrated starts to calibrate the zero point value thereof, records the zero point value a1 and the AD value corresponding to the zero point value as AD1.
Specifically, the zero value collected by the sensor is an analog quantity, and the AD value is a value obtained by converting the analog quantity into a digital quantity. Here, the above a1 and AD1 may be referred to as initial air pressure data.
(2) After the operation (1) of the sphygmomanometer to be calibrated is completed, the initial air pressure data is fed back to the control unit 10, so that the control unit 10 obtains the initial feedback.
In the specific implementation, after the sphygmomanometer to be calibrated with the communication function obtains the initial air pressure data, the two data are directly and synchronously fed back to the control unit 10; when the sphygmomanometer to be calibrated without the communication function is calibrated, a user starts the sphygmomanometer calibration equipment after checking that the sphygmomanometer to be calibrated calibrates the initial air pressure data, and synchronously calibrates the initial air pressure data.
And S2, acquiring the air pressure value of the air stabilizing unit 112 through the sensor circuit 111 after the initial feedback is acquired.
Specifically, after acquiring the initial feedback, the control unit 10 issues an inflation instruction to the sphygmomanometer to be calibrated, so that the sphygmomanometer to be calibrated is inflated. Further, after the control unit 10 obtains the initial feedback, it sets zero synchronously to ensure that the air pressure value collected by the sensor circuit 111 is the actually monitored air pressure value.
Further, after receiving the inflation command, the sphygmomanometer to be calibrated controls the air pump and the electromagnetic valve to be closed so as to start inflation operation. In this process, the gas stabilizing unit 112 is connected to the sphygmomanometer to be calibrated, so that the pressure existing in the gas stabilizing unit 112 is the pressure of the sphygmomanometer to be calibrated, and the inflation pressure during the inflation process can be collected by the sensor circuit 111, and a corresponding pressure value can be obtained.
In a specific implementation, the sphygmomanometer calibration apparatus further includes a display unit connected to the control unit 10; the control unit 10 is further configured to send the air pressure value collected by the sensor circuit 111 in the gas sensing unit 11 to the display unit for displaying.
And S3, obtaining target air pressure data of the sphygmomanometer to be calibrated until the air pressure value meets the preset air pressure value.
Specifically, when the air pressure value acquired by the sensor circuit 111 approaches a specific air pressure value, the control unit 10 sends an inflation stop instruction to the sphygmomanometer to be calibrated, so that the sphygmomanometer to be calibrated stops inflating.
In a specific implementation, when the sphygmomanometer to be calibrated includes a communication function, the specific barometric pressure value may be 310mmHg, and when the sphygmomanometer to be calibrated does not have the communication function, the specific barometric pressure value may be 300mmHg. Wherein, whether the sphygmomanometer to be calibrated without the communication function stops inflating is determined by manual identification of a user. In a specific implementation, the sphygmomanometer to be calibrated further comprises a marking key, and when the user checks through the display unit that the air pressure value of the sphygmomanometer to be calibrated without the communication function reaches 300mmHg, the user presses the marking key of the sphygmomanometer to be calibrated to mark the AD value corresponding to the specific air pressure value, wherein the AD value is marked as AD2. The 300mmHg pressure value is the target pressure data of the sphygmomanometer to be calibrated without communication function, and the target pressure data is marked as a2.
In specific implementation, after the sphygmomanometer to be calibrated receives the inflation stopping instruction, the air pump and the electromagnetic valve of the sphygmomanometer are controlled to stop working, and at the moment, the sphygmomanometer to be calibrated does not perform inflation operation any more.
Furthermore, the sphygmomanometer to be calibrated including the communication function needs to detect the stability of the inflation gas, that is, the sphygmomanometer to be calibrated determines whether the inflation gas is stable according to whether the fluctuation of the inflation gas is smaller than a certain AD value. When the fluctuation of the inflation gas is smaller than a certain AD value, the sphygmomanometer to be calibrated sends a data acquisition request to the sphygmomanometer calibration apparatus, and then the control unit 10 of the sphygmomanometer calibration apparatus acquires the air pressure value of the sphygmomanometer to be calibrated at that time, which is the target air pressure data, and at that time, the target air pressure data is also denoted as a2.
Specifically, after the control unit 10 acquires the target air pressure data of the sphygmomanometer to be calibrated including the communication function, the control unit also sends the target air pressure data to the sphygmomanometer to be calibrated, and further, after the sphygmomanometer to be calibrated receives the target air pressure data, an AD value corresponding to the target air pressure data is also synchronously recorded, and the AD value is also recorded as AD2.
And S4, acquiring correction data determined by the sphygmomanometer to be calibrated based on the initial feedback and the target air pressure data.
In a specific implementation, the sphygmomanometer to be calibrated is operated according to the initial feedback initial air pressure data a1 and AD1, the target air pressure data a2 and the corresponding AD2 by a preset formula to obtain a corrected sphygmomanometer sensor operation value, specifically, the sphygmomanometer sensor operation value may be obtained by the following formula: k = (AD 2-AD 1)/(a 2-a 1).
Further, after the calculation is completed, a specific numerical value of the calculated value of the sphygmomanometer sensor can be obtained, and then the sphygmomanometer to be calibrated stores the specific numerical value.
Further, after the specific value is obtained by the sphygmomanometer to be calibrated, feedback is provided to the sphygmomanometer calibration device, and then a check calibration data command is issued to the sphygmomanometer to be calibrated by the sphygmomanometer calibration device. At this time, the sphygmomanometer to be calibrated starts to inflate again, and obtains the air pressure value acquired by the sphygmomanometer sensor according to the specific numerical value. And then, the sphygmomanometer to be calibrated interacts the air pressure value with the sphygmomanometer calibration equipment, wherein the air pressure value is the correction data.
In a specific implementation, the sphygmomanometer to be calibrated without the communication function is also identified manually.
And S5, determining a calibration feedback result according to the correction data and the air pressure value corresponding to the correction data.
Specifically, the sphygmomanometer calibration device further obtains a current air pressure value acquired by the sphygmomanometer calibration device according to the air sensing unit 11, where the current air pressure value is an air pressure value corresponding to the correction data.
In a specific implementation, the sphygmomanometer calibration apparatus compares the correction data with the air pressure value corresponding to the correction data, so as to obtain the calibration feedback result.
Further, the display unit may further display air pressure data sent by the sphygmomanometer to be calibrated and a calibration result of the sphygmomanometer to be calibrated, specifically, the air pressure data may be the correction data, and the calibration result may be the calibration feedback result.
And S6, when the calibration feedback result meets a preset deviation threshold, determining that the sphygmomanometer to be calibrated completes calibration.
In a specific implementation, when the difference between the correction data and the comparison data of the air pressure value corresponding to the correction data is within a specified range, the calibration of the sphygmomanometer to be calibrated is completed, and then the sphygmomanometer calibration device sends a success command. The predetermined range is the preset deviation threshold, and the specific value of the preset deviation threshold may be determined according to the user requirement, which is not limited herein.
Further, whether the sphygmomanometer to be calibrated without the communication function meets the preset deviation threshold value is determined through manual identification.
Further, after the calibration of the sphygmomanometer calibration apparatus is completed, the following step S7 is also executed:
and S7, obtaining test air pressure data sent by the sphygmomanometer to be calibrated, and determining an air pressure stabilization result of the sphygmomanometer to be calibrated based on the test air pressure data.
In a specific implementation, after the calibration of the sphygmomanometer calibration apparatus is completed, the control unit 10 of the sphygmomanometer calibration apparatus further sends a leak detection mode instruction to the sphygmomanometer to be calibrated, then the sphygmomanometer to be calibrated starts a leak detection mode to obtain corresponding test air pressure data, and then the sphygmomanometer to be calibrated provides the test air pressure data to the sphygmomanometer calibration apparatus to determine whether the data indicates that the air pressure is stable, so as to obtain the air pressure stabilization result. When the judgment result indicates that the air pressure is stable, the sphygmomanometer calibration equipment sends a success signal to the sphygmomanometer to be calibrated, and at the moment, the sphygmomanometer to be calibrated exits the leakage detection mode and the calibration mode.
