Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1, the present application provides a digital electronic sphygmomanometer, which can store blood pressure measurement data in a certain data statistics period in a traceable manner, automatically analyze the blood pressure measurement data to determine the blood pressure stability of a user, and meanwhile, in order to avoid the problem of large data traceability errors caused by use of other family members, in this embodiment, the present application distinguishes users by analyzing different voltage boosting and reducing curves of the electronic sphygmomanometer and using different inflation amounts of the electronic sphygmomanometer, and stores blood pressure measurement results of different users in different storage units respectively, so as to implement classification operation of blood pressure monitoring results of different users, thereby achieving the purposes of data tracing and monitoring blood pressure stability.
Comprising the following steps:
the blood pressure measuring body 1 is provided with an inflator and a data processing module 5.
The occlusion cuff 2 is connected with an inflator pump through an air guide pipeline and is generally tied at a position where the arm and the right atrium are level and high.
The pressure sensor 3 is disposed inside the occlusion cuff 2 and the sensing surface of the pressure sensor 3 faces the arm, and the pressure sensor 3 is used for monitoring the pressure value of the arm under the inflation action of the occlusion cuff 2, and it should be specifically noted that the pressure sensor 3 of the present embodiment is not used for monitoring the air pressure of the air bag inside the occlusion cuff 2 after being inflated, but is used for monitoring the pressure of the arm under the inflation extrusion action of the occlusion cuff 2, so that the difference between the two output results of the pressure sensor 3 is not only related to the inflation speed and the deflation speed, but also related to the muscle mass of the user.
Specifically, for example, the pressure sensor 2 is required to detect a pressure value change smaller than that of the young person in the early stage of inflation because the muscle of the old person is relaxed when the old person is used and the young person is used, and the pressure value change curves are different although the pressure value at the time of final inflation is the same in order to ensure a good monitoring result, so that different users are identified through the pressure change curves to screen blood pressure measurement data of the users frequently used.
The inflation monitoring assembly 4 comprises a flow sensor arranged at an output port of the inflator pump and is used for monitoring the gas flow of the inflator pump for inflating the occlusion cuff 2 in unit time, and different users are identified by identifying the inflation gas amount of the inflator pump because the binding degrees of the occlusion cuffs 2 corresponding to different users are different.
The data processing module 5 comprises a user editing unit 51, a user identification unit 52 and a blood pressure monitoring value classification storage unit 53.
The user editing unit 51 is used for adding or subtracting users of the sphygmomanometer, for example, the user editing unit 51 has two commonly used users, when the user identification unit 52 identifies that the currently used user does not belong to any user in the user editing unit 51, the blood pressure monitoring data is automatically screened out, only temporary measurement is realized at this time, the data tracing function is not provided, and when the user identification unit 52 identifies that the currently used user belongs to a certain user of the user editing unit 51, the blood pressure monitoring value is stored in the corresponding storage unit through the blood pressure monitoring value classification storage unit 53.
The user identity identifying unit 52 includes a boost-buck speed calculating unit 521 and an inflation amount calculating unit 522, where the boost-buck speed calculating unit 521 is configured to calculate the boost-buck speed of the monitored data of the pressure sensor 3 when the inflation speed and the deflation speed of the inflation pump are the same, the boost-buck speeds corresponding to different users at the same inflation speed are not identical, the inflation amount calculating unit 522 is configured to determine the total inflation amount according to the monitoring duration of the flow sensor and the unit inflation amount of the inflation pump, and the total inflation amount of the inflation pump for inflating the occlusion cuffs 2 worn by different users to the rated pressure is not identical.
The data processing module 5 uses the up-down pressure rate acquired by the up-down pressure rate calculating unit 521 and the total inflation amount acquired by the inflation amount calculating unit 522 as a marking signal for identifying the user.
As a preferred mode of this embodiment, the data processing module 5 receives the initial pressure of the arm bound by the occlusion cuff 2 in real time after the pressure sensor 3 is powered on, the data processing module 5 further includes a cuff posture reminding module 55, and the cuff posture reminding module 55 prompts the user to readjust the binding posture of the occlusion cuff 2 according to the comparison result of the initial pressure and the standard error range, and improves the accuracy of blood pressure monitoring by identifying the initial pressure of the arm bound on the one hand, because the arm bound is too loose, the acting force on the arm of the user cannot meet the rated pressure, the problem of low accuracy of blood pressure monitoring is caused, and on the other hand, the arm bound is too tight, and the blood pressure measurement value is higher than the intravascular pressure.
In addition, in combination with the working principle of the user identification unit 52 of this embodiment, the cuff posture reminding module 55 plays a vital role in monitoring the inflation amount of different users and the accuracy of the output data of the pressure sensor 3, and once the occlusion cuff 2 used by the user is too loose and too tight to bind the arm, the output data change value and inflation amount of the pressure sensor are directly affected, so the cuff posture reminding module 55 is not only used for reminding the user to measure the blood pressure in a standard manner, but also for improving the accuracy of the calculation data of the lifting pressure rate calculation unit 521 and the inflation amount calculation unit 522.
The data processing module 5 acquires output data of the pressure sensor 3 in real time during inflation and deflation of the inflator, the up-down pressure rate calculating unit 521 generates a two-dimensional measurement timing chart of the applied pressure-time based on the output data of the pressure sensor 3 and the measurement time, and the data processing module 5 regulates the inflator to suspend the inflation operation when the applied pressure is the same as a set value.
After the data processing module 5 recognizes the user identity using the sphygmomanometer, the blood pressure monitoring values of different users are automatically classified and stored in different storage units of the blood pressure monitoring value classification storage unit 53.
The inflation amount calculating unit 522 calculates the total inflation amount at which the inflation pump inflates the occlusion cuff 2 to the same applied pressure as the rated pressure, based on the measurement time at which the applied pressure is the same as the rated pressure and the measurement data of the flow sensor.
The data processing module 5 establishes a mathematical model of the inflation amount between the total inflation amount and the circumference of the user through multiple measurement operations, and the data processing module 5 distinguishes different circumferences according to the difference of the total inflation amount so as to further identify the current user.
The up-down pressure rate calculating unit 521 is configured to acquire the pressure value detected by the pressure sensor 3 at fixed time in the process of starting inflation by the inflator, completing inflation, and ending deflation, establish a pressure measurement timing chart between the applied pressure and time, and calculate the up-pressure rate from the start of inflation to the completion of inflation, and the down-pressure rate from the completion of inflation to the end of deflation.
The data processing module 5 establishes a mathematical model of the boost rate, the buck rate and the boost-buck between the user's muscle masses through a plurality of measurement operations, the data processing module 5 distinguishing between different muscle masses according to the overall difference in boost rate and buck rate to further distinguish the current user.
The data processing module 5 automatically adds the pressure-increasing rate error range corresponding to the muscle mass of each user and the total inflation amount error range corresponding to the arm circumference of each user to the user editing unit 51, and when the pressure-increasing rate and the total inflation amount are both in the pressure-increasing rate error range and the total inflation amount error range of a certain user, the data processing module 5 automatically determines the user using the sphygmomanometer and stores the blood pressure monitoring value in the storage unit matched with the user.
In this embodiment, in order to distinguish blood pressure monitoring values of different users, or achieve the use work of multiple users of one sphygmomanometer, account numbers of different users can be directly established, corresponding users are directly selected during measurement, and measurement results can be stored in corresponding user account numbers, but in many cases, people often forget to select account numbers or directly select wrong account numbers during middle-aged and elderly use, so that unstable and disordered conditions exist in statistics and tracing of blood pressure detection data.
The present embodiment does not rely on manual selection of account numbers, but analyzes the difference of pressures detected by the pressure sensor 2 of different users in the same pump working state through microscopic angles to distinguish muscle states of different users and distinguish users according to the difference of muscle states, so that even if the user does not select user account numbers in advance, the present embodiment can confirm the user using the sphygmomanometer by thinning and identifying the muscle states of the user.
Similarly, because the arm circumferences of the users are different or the muscles are different, when the arms of the users are subjected to the same pressure, the inflation amount of the inflation pump is different, so that the calculation result of the inflation amount calculation unit 522 is used as another mark for identifying the users, after the standard use of the sphygmomanometer is carried out by each user, the inflation amount and the lifting pressure rate corresponding to the user are within a certain error range, the identity of the user is determined according to the inflation amount and the lifting pressure rate calculated by the current user by using the sphygmomanometer, and the blood pressure monitoring value is correspondingly stored in the storage unit of the user.
In addition, since the blood pressure measured in different time periods is very different, in order to monitor the blood pressure change of the user in one week or two weeks or even one month, the use time of measuring the blood pressure by using the sphygmomanometer needs to be distinguished, and the stability statistics is performed on the blood pressure measured in the same time period or the same time point respectively, so that the blood pressure measuring device has a reference value, each storage unit is used for storing the blood pressure monitoring value and the blood pressure monitoring time point of the user which are uniquely matched, and the blood pressure monitoring time point is divided into a plurality of monitoring time periods according to the time of day, for example, the morning monitoring time period, the afternoon monitoring time period and the night monitoring time period respectively, and the storage unit of each user is divided into a plurality of storage spaces.
Each storage space is matched with a corresponding monitoring period, the same storage space is used for storing the blood pressure monitoring value of the same monitoring period, the data processing module 5 determines the monitoring period where the monitoring data are located according to the blood pressure monitoring time point where the blood pressure monitoring value is obtained, and the blood pressure monitoring value and the blood pressure monitoring time point are correspondingly stored in the matched storage space.
Of course, since the posture is not used, there is a high possibility that an error is measured, and there is error data, the data processing module 5 further includes a rejection unit 54, the rejection unit 54 is configured to delete the error data in each storage space, the data processing module 5 determines a measurement reference range of the user in each storage space in the data statistics period according to the data distribution of the blood pressure monitoring values stored in each storage space, and compares the blood pressure monitoring value measured each time with the measurement reference range, and when the blood pressure monitoring value exceeds the measurement reference range, the rejection unit 54 deletes the blood pressure monitoring value.
For example, if the data statistics period of the user is one week, the measurement reference range of the blood pressure monitoring value at a fixed measurement time point in the week is (70±10, 120±20), if the blood pressure monitoring value exceeds the measurement reference range, it is highly likely that the measured posture is not right, at this time, the user is required to readjust the posture measurement, and the measurement data at this time is erroneous data, and is not required to be stored in a storage unit, otherwise, the accuracy and stability of the whole data statistics period are affected.
The data processing module 5 establishes a mathematical analysis model for the blood pressure monitoring values in the storage space, which are in accordance with the measurement reference range, forms a blood pressure monitoring value change curve of the same monitoring period in a plurality of days, and judges the stability of the blood pressure monitoring values of the same monitoring period in a plurality of days.
At present, many electronic blood pressure meters are not designed to be of a sleeve containing structure, and because the electronic blood pressure meters are convenient to carry, the electronic blood pressure meters are often carried along, are placed in a trunk, and are likely to cause loss to a pressure sensor under continuous collision and extrusion, so that the service life is shortened.
By collecting and summarizing the arm sleeves, the sleeves are not directly exposed when the portable type hand-held arm is carried, so that the service life is prolonged, but the portable type hand-held arm is also required to be taken into consideration in the aspects of structure and volume, and the portable type hand-held arm is stored on the premise of not increasing the existing volume as much as possible.
