In addition, the blood pressure sample data are embedded into the blood pressure simulator, so that 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 illustrates a blood pressure acquisition device of an embodiment of the present disclosure. The device comprises: the device comprises a controller 1, an inflation and deflation control module 2, a gas pressure sensor 3, a data storage module 5, a functional module 6, a communication interface 7 and a gas circuit interface 9 which are arranged outside the device.
As shown in fig. 1, a controller 1 is respectively connected with a functional module 6, a data storage module 5, an inflation and deflation control module 2, a gas pressure sensor 3 and a communication interface 7, the gas pressure sensor 3 is respectively connected with the inflation and deflation control module 2 and a gas path interface 9, and an electromagnetic valve 12 is arranged 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 module 6-2 arranged inside the device.
Specifically, the controller 1 is configured to control the above-described functional modules 6, the data storage module 5, the inflation/deflation control module 2, the gas pressure sensor 3, and the operating states 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, complete measurement of systolic pressure and diastolic pressure, ensure linear deflation rate particularly in the blood pressure measurement stage, realize stable acquisition of blood pressure signals (which can comprise a blood pressure waveform curve) and improve the accuracy of blood pressure acquisition; preferably, the above-mentioned deflation rate may be 2mmHg/s. The gas pressure sensor 3 is used for detecting pressure changes in the gas path connected with the cuff and deriving relevant blood pressure data signals. The key display module 6-1 in the functional module 6 provides keys for data input such as blood pressure acquisition type selection and blood pressure measurement, and a screen for displaying blood pressure indication values and blood pressure waveform curves; the power module 6-2 provides the power supply function for the device. The data storage module 5 is used for storing the blood pressure signal and the blood pressure value, and the blood pressure value is calculated 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/deflation control module 2, respectively.
Further, fig. 2 shows a blood pressure acquisition device of other embodiments of the present disclosure. As shown in fig. 2, the device is connected with an air passage of an external cuff 11 through an air passage interface 9, so that the change condition of the blood pressure of the tested person is transmitted to the air pressure sensor 3 through air passage conduction. The communication interface 7 is connected with an external computer 8, so that the device can transmit the collected blood pressure signals, blood pressure values and other blood pressure data to the computer for subsequent processing, and blood pressure sample data is generated. Optionally, the air passage interface 9 is connected with an air passage of the cuff 11 through the air pressure sensor 3.
On the one hand, the blood pressure acquisition device calculates the acquired blood pressure signals through the built-in algorithm to obtain the blood pressure values, and the related algorithm has many and no fixed standards, so that the blood pressure values actually corresponding to the blood pressure signals cannot be accurately expressed. Therefore, in the present embodiment, the blood pressure acquisition device generates only the blood pressure signal, and the blood pressure value does not need to be calculated by the built-in algorithm. On the other hand, auscultation (Korotkoff sound method) is a standard accepted by current blood pressure measurement, in order to ensure that blood pressure data establishes a traceability relationship with a real blood pressure indication value of a human body as far as possible, in the blood pressure acquisition process, a table mercury column sphygmomanometer 10 and a cuff 11 are utilized to measure blood pressure values through blind measurement, the measured blood pressure values obtained through measurement are manually input into the device through a key display module 6-1, and then the measured blood pressure values are in one-to-one correspondence with acquired blood pressure signals, so that blood pressure data is obtained. That is, the blood pressure data finally outputted to the computer 8 in the present apparatus includes the blood pressure signal collected by the air 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 is that two professional medical staff independently read the measured blood pressure values (systolic blood pressure and diastolic blood 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 as much as possible. In general, the blood pressure acquisition device in this embodiment will take an average value as the final blood pressure value 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 when the difference between the readings of two persons is not more than 2 mmHg. The blood pressure data processed in the computer 8 can establish a real human blood pressure database, and can be embedded into the real human blood pressure database according to the communication modes of different blood pressure detection devices or blood pressure simulators to serve as blood pressure sample data for standby.
As some alternative 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, a USB (Universal Serial Bus ) interface.
The process of collecting real human blood pressure data is specifically as follows: the cuff 11 of the table-type mercury sphygmomanometer 10 is rolled up on the upper arm of the subject. Generally, in order to ensure the stability of the blood pressure acquisition signal, the cuff 11 should be rolled at a proper position of the upper arm, and smooth conduction of the cuff 11 to the trachea is ensured without deformation. The selection key display module 6-1 is provided with a selection sample curve acquisition and determination key, the blood pressure acquisition device starts to work, the inflation and deflation control module 2 can replace a manual air bag of the traditional table-type mercury sphygmomanometer 10, the automatic inflation and deflation functions are 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 trend of the blood pressure signal (namely, the blood pressure waveform curve) in real time, and the user can decide whether to continue the collection work according to the signal stability of the waveform. The gas pressure sensor 3 detects the pressure change in the gas path to collect the blood pressure signal, and meanwhile, the blood pressure collecting device calculates the blood pressure value corresponding to the final blood pressure signal through the measured blood pressure value input by the medical staff at the key display module 6-1, and the blood pressure signal 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. Furthermore, the blood pressure data number can be transmitted to the computer 8 in real time as an RS-232 interface for further data processing, or can be saved to a mobile storage device such as a USB (universal serial bus) interface for subsequent data processing.
Through the blood pressure acquisition device provided by the embodiment of the disclosure, acquired blood pressure data can be output, the computer generates blood pressure sample data through the blood pressure data, a plurality of blood pressure sample data form a blood pressure sample database of a real human body, and a traceability relationship between the blood pressure sample data and the blood pressure value of the real human body is established. In addition, the blood pressure sample data are embedded into the blood pressure simulator, so that 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, where the electronic korotkoff sound sensor 13 is connected to the air path interface 9, and is used for detecting the variation of korotkoff sound signals during the blood pressure collecting process. The connecting conduit of the cuff 11 is connected with external blood pressure measuring equipment through the air passage interface 9, and pressure change signals and Korotkoff sound change signals in the air passage can be respectively acquired through the air pressure sensor 3 and the Korotkoff sound sensor 13. The Korotkoff sound signal change curve can be synchronously displayed on the screen of the key display module 6-1, and can be used as a comparison reference of pulse wave blood pressure signals to observe the stability of waveforms in the blood pressure acquisition process. That is, the blood pressure acquisition device provided in this embodiment further includes a recording function for recording a change process of the blood pressure waveform signal in the blood pressure simulation process, and implementing verification of 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 waveform change curve of the blood pressure under constant pressure and perform calculation processing in the calibration process. As shown in fig. 2, the invention can realize the record of the signal through the connection of the gas pressure sensor 3, the blood pressure simulator 14 and the pressure gauge 15, and the record is stored in the data storage module 5, and the acquired blood pressure waveform curve can be synchronously displayed in the screen of the key display module 6-1. And is subsequently connected to the computer 8 through a data interface, so that the collected data can be subjected to subsequent processing.
In this blood pressure collection mode, the pressure gauge provides a constant pressure because of recording the simulated change of the blood pressure at a constant pressure, and the blood pressure simulator 14 is provided in an operating state of blood pressure simulation to simulate the occurrence of a blood pressure signal. At this time, the inflation and deflation control module 2 is not required to realize automatic inflation and deflation functions in the acquisition process of the blood pressure analog signal, 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 circuit is not conducted. The blood pressure signal generated by the blood pressure simulator 14 can be acquired by the gas pressure sensor 3 and recorded and stored.
Still further, as shown in fig. 2, the functional module 6 further includes an overpressure alarm module 6-3 disposed outside the device, and the overpressure alarm module 6-3 is used for continuously alarming faults occurring during the inflation process. In general, during the blood pressure acquisition process, the inflation/deflation control module 2 will inflate the cuff 11 during the inflation process, and if there is a failure in the inflation/deflation control module 2 or the measurement mode is not suitable (for example, the cuff 11 is too loose or too tight), an inflation overpressure will be caused. At this time, after the controller 1 detects that the above situation occurs, the overvoltage alarm module 6-2 is controlled to perform a buzzing alarm, and a red overvoltage alarm indicator lamp (as shown in fig. 4) is flashed, so that the process of blood pressure collection is automatically stopped, and the safety of the device is improved.

In the specific implementation process, the tested object places the cuff 11 at a proper position, and the functions of continuous blood pressure acquisition or timing and timing acquisition are 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 by detecting the pressure change in the gas path, and the acquired blood pressure signals can show the change trend of the waveform of the blood pressure curve and the monitored blood pressure value in real time on the screen of the case display module 6-1 of the blood pressure acquisition device after the filtering treatment of the data processing module 4 and the calculation of the blood pressure value. Further, the collected blood pressure data can be stored in the data storage module 5 as well, and can be transmitted to the computer 8 for further processing through the communication interface 7 as required.
