The blood pressure detection device is used as a main blood pressure measuring tool, and the accuracy of the blood pressure detection device needs to be calibrated by using a metering calibration device so as to ensure the reliability of the detection result. Generally, a medical structure measures and calibrates a blood pressure monitoring device by using a blood pressure simulator, and the blood pressure simulator can generate a corresponding oscillation wave according to a predetermined blood pressure value to simulate a blood pressure generating process of a human body.

In addition, the blood pressure sample data is embedded into the blood pressure simulator, and the metering performance of the blood pressure verification device is optimized.
The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 shows a blood pressure collecting device according to an embodiment of the present disclosure. The device includes: the device comprises a controller 1, an inflation and deflation control module 2, a gas pressure sensor 3, a data storage module 5 and a functional module 6 which are arranged inside the device, and a communication interface 7 and a gas circuit interface 9 which are arranged outside the device.
As shown in fig. 1, the controller 1 is connected to the function module 6, the data storage module 5, the inflation and deflation control module 2, the gas pressure sensor 3, and the communication interface 7, the gas pressure sensor 3 is connected to the inflation and deflation control module 2 and the gas path interface 9, and the electromagnetic valve 12 is disposed between the gas pressure sensor 3 and the inflation and deflation control module 2. The functional module 6 comprises a key display module 6-1 arranged outside the device and a power supply module 6-2 arranged inside the device.
Specifically, the controller 1 is configured to control the functional module 6, the data storage module 5, the inflation/deflation control module 2, the gas pressure sensor 3, and the working state of the gas pressure sensor. When the electromagnetic valve 12 is in an open state, the inflation and deflation control module 2 can realize automatic inflation and deflation functions in the blood pressure measurement process, so as to complete measurement of systolic pressure and diastolic pressure, especially ensure linear deflation rate in the blood pressure measurement stage, realize stable collection of blood pressure signals (which can include a blood pressure waveform curve), and improve the precision of blood pressure collection; preferably, the above-mentioned air bleeding rate may be 2 mmHg/s. The gas pressure sensor 3 is used for detecting the pressure change in the gas path connected with the cuff and deriving the relevant blood pressure data signal. A key display module 6-1 in the functional module 6 provides keys for data input such as blood pressure acquisition type selection, blood pressure value measurement and the like, and a screen for displaying a blood pressure indicating value and a blood pressure waveform curve; the power module 6-2 provides the device with a power supply function. The data storage module 5 is used for storing the blood pressure signal and the blood pressure value, and the blood pressure value is obtained by calculation based on the measured blood pressure value received by the key display module 6-1.
Optionally, the controller 1 is electrically connected to the gas pressure sensor 3 and the inflation and deflation control module 2, respectively.
Further, fig. 2 shows a blood pressure collection device according to further embodiments of the present disclosure. As shown in fig. 2, the device is connected to the air passage of an external cuff 11 through an air passage interface 9, so that the blood pressure change of the person to be measured is transmitted to the air pressure sensor 3 through the air passage. The communication interface 7 is used for being connected with an external computer 8, so that the device can transmit the collected blood pressure data such as blood pressure signals, blood pressure values and the like to the computer for subsequent processing, and blood pressure sample data is generated. Optionally, the air passage interface 9 is connected with the air passage of the cuff 11 through the air pressure sensor 3.
On one hand, the blood pressure collecting device calculates the collected blood pressure signal through a built-in algorithm to obtain the blood pressure value, and related algorithms have many and no fixed standards, so that the blood pressure value actually corresponding to the blood pressure signal cannot be accurately expressed. Therefore, in the present embodiment, the blood pressure collecting device generates only the blood pressure signal, and does not need to calculate the blood pressure value by a built-in algorithm. On the other hand, the auscultatory method (korotkoff sound method) is a standard accepted by blood pressure measurement at present, in order to ensure that the blood pressure data establishes a traceability relation with the real human blood pressure indication value as much as possible, in the blood pressure acquisition process, a table mercury column sphygmomanometer 10 and a cuff 11 are used, the blood pressure value is measured through a blind method, the measured blood pressure value obtained through measurement is manually input into the device through a key display module 6-1, and then the measured blood pressure value is in one-to-one correspondence with the acquired blood pressure signals, so that the blood pressure data is obtained. That is, the blood pressure data finally output to the computer 8 in the present apparatus includes the blood pressure signal collected by the gas pressure sensor 3 and the measured blood pressure value corresponding to the blood pressure signal received through the key display module 6-1.
Specifically, the blind measurement in this embodiment means that two professional medical staff independently read the measured blood pressure values (systolic pressure and diastolic pressure) from the table-type mercury sphygmomanometer 10 at the same time, and each medical staff does not know the reading recorded by the other medical staff or displayed by the table-type mercury sphygmomanometer 10, so as to improve the accuracy of the blood pressure measurement value as much as possible. Generally, the blood pressure collecting device in this embodiment will take the average value as the final blood pressure value when the difference between the readings of the two persons does not exceed 2mmHg, and store the final blood pressure value and the corresponding blood pressure signal in the data storage module 5 in a one-to-one correspondence manner. The blood pressure data processed in the computer 8 can establish a real human body blood pressure database, and can be embedded into the blood pressure data database as blood pressure sample data for standby according to the communication modes of different blood pressure detection devices or blood pressure simulators.
As some optional embodiments of the present invention, the communication interface may specifically include an RS-232 (Serial binary data exchange interface between the data terminal device and the data communication device) interface, and a USB (Universal Serial Bus) interface.
The process of collecting the real human blood pressure data is as follows: the cuff 11 of the desk-top mercury sphygmomanometer 10 is wrapped around the upper arm of the subject. Generally, to ensure the stability of the blood pressure collecting signal, the cuff 11 should be rolled at a proper position on the upper arm, and the smooth conduction of the cuff 11 connected with the trachea is ensured without deformation. The selection button display module 6-1 is provided with a selection sample curve acquisition and determination button, the blood pressure acquisition device starts to work, the inflation and deflation control module 2 can replace a manual air bag of a traditional table type mercury column sphygmomanometer 10, the automatic inflation and deflation function is realized at a linear speed in the blood pressure measurement process, and the accuracy of blood pressure measurement is improved. The screen of the key display module 6-1 can display the variation trend of the blood pressure signal (namely, the blood pressure waveform curve) in real time, and a user can determine whether to continue to collect the blood pressure signal according to the signal stability of the waveform. The gas pressure sensor 3 realizes the collection of blood pressure signals by detecting the pressure change in the gas path, meanwhile, the blood pressure collecting device calculates the blood pressure value corresponding to the blood pressure signals finally through the measured blood pressure value input by medical personnel in the key display module 6-1, and the blood pressure signals and the blood pressure value are stored in the data storage module as a group of blood pressure data after being in one-to-one correspondence. Further, the blood pressure data number can be transmitted to the computer 8 in real time through being used as an RS-232 interface for the next data processing, and the data can also be stored in a USB (universal serial bus) interface and other mobile storage devices for the subsequent data processing.
According to the blood pressure acquisition device provided by the embodiment of the disclosure, the acquired blood pressure data can be output, the computer generates blood pressure sample data through the blood pressure data, the plurality of blood pressure sample data form a blood pressure sample database of a real human body, and a traceability relation between the blood pressure sample data and a blood pressure value of the real human body is established. In addition, the blood pressure sample data is embedded into the blood pressure simulator, and the metering performance of the blood pressure verification device is optimized.
As some optional embodiments of the present invention, as shown in fig. 2, the blood pressure collecting device further includes an electronic korotkoff sound sensor 13 disposed inside the device, and the electronic korotkoff sound sensor 13 is connected to the air channel interface 9 for detecting a change of a korotkoff sound signal during the blood pressure collecting process. The connecting conduit of the cuff 11 is connected with external blood pressure measuring equipment through an air passage interface 9, and a pressure change signal and a Korotkoff sound change signal in an air passage can be acquired through the air pressure sensor 3 and the Korotkoff sound sensor 13 respectively. The Korotkoff's sound signal change curve can be synchronously displayed in a screen of the key display module 6-1 and used as a contrast reference of the pulse wave blood pressure signal, and the waveform stability degree in the blood pressure acquisition process can be observed. That is to say, the blood pressure collecting device provided by this embodiment further includes a recording function, which is used for recording the change process of the blood pressure waveform signal in the blood pressure simulation process, and realizes the verification of the metering performance thereof in cooperation with the blood pressure simulator.
Furthermore, the blood pressure simulator needs to extract waveform amplitude or frequency information according to the blood pressure waveform change curve under constant pressure and perform calculation processing in the calibration process of the blood pressure simulator. As shown in fig. 2, the invention can record the signal through the connection of the gas pressure sensor 3 with the blood pressure simulator 14 and the pressure gauge 15, and store the signal in the data storage module 5, and the acquired blood pressure wave curve can be synchronously displayed in the screen of the key display module 6-1. And is connected to the computer 8 through a data interface, so that the acquired data can be subjected to subsequent processing.
In this blood pressure collection mode, since the change of the blood pressure under a constant pressure is recorded, the constant pressure is supplied from the pressure gauge, and the blood pressure simulator 14 is set in an operating state of blood pressure simulation to simulate the generation of a blood pressure signal. At this time, the automatic inflation and deflation functions of the inflation and deflation control module 2 are not required to be realized in the acquisition process of the blood pressure analog signals, the electromagnetic valve between the gas pressure sensor 3 and the inflation and deflation control module 2 is in a closed state, and the gas path is not conducted. The blood pressure signal generated by the blood pressure simulator 14 can be collected and recorded and stored by the gas pressure sensor 3.
Still further, as shown in fig. 2, the functional module 6 further comprises an overpressure alarm module 6-3 arranged outside the device, and the overpressure alarm module 6-3 is used for continuously alarming faults occurring in the inflation process. Generally, during the blood pressure collection process, the inflation and deflation control module 2 inflates the cuff 11 during the inflation process, and if the inflation and deflation control module 2 has a fault or the measurement mode is not appropriate (for example, the cuff 11 is rolled too loosely or too tightly), the inflation overpressure condition is caused. At this time, after the controller 1 detects that the above condition occurs, the overvoltage alarm module 6-2 is controlled to buzz and alarm, and a red overvoltage alarm indicator lamp (as shown in fig. 4) flashes, so that the process of collecting the blood pressure is automatically stopped, and the safety of the device is improved.

In this embodiment, the blood pressure collecting device can also be used as a basic blood pressure collecting device, and in some occasions where continuous measurement or fixed-time and fixed-time measurement of blood pressure is required, the blood pressure signal collection and recording are realized, so that long-term and real-time monitoring of the blood pressure change condition of the measured object is facilitated.

In the specific implementation process, the cuff 11 is placed at a proper position by the object to be tested, and the continuous blood pressure acquisition or the timed and timed acquisition function is selected according to the requirement. The inflation and deflation control module 2 realizes the automatic inflation and deflation functions of the cuff 11 through the gas pressure sensor 3, the gas pressure sensor 3 realizes the acquisition of blood pressure signals through detecting the pressure change in the gas path, and after the acquired blood pressure signals are subjected to filtering processing and blood pressure value calculation through the data processing module 4, the change trend of the blood pressure curve waveform and the monitored blood pressure value can be displayed on the screen of the case display module 6-1 of the blood pressure acquisition device in real time. Furthermore, the collected blood pressure data can also be stored in the data storage module 5 and can be transmitted to the computer 8 through the communication interface 7 for further processing as required.
