Description
Technical Field
The invention relates to the technical field of medical auxiliary instruments, in particular to portable intelligent medical measuring equipment.
Background
At present, a common measurement method related to blood pressure in hospitals or daily life is an indirect measurement method, namely a cuff pressurization method, the height of mercury columns or pointers are used for judging and measuring the blood pressure, and the portability is poor.
Common methods for measuring blood pressure include calculating blood pressure from heart rate, comprehensively determining blood pressure values by means of PPG (PhotoPlethysmoGraphy), which is abbreviated as PPG (PhotoPlethysmoGraphy), ECG (Electrocardiogram), and obtaining blood pressure data from feature points of a single PPG. The principle of the above method is that a photoplethysmography is used, namely, an LED on a sensor is used for emitting light with a specific frequency band to penetrate through the skin, a receiving device on the sensor is used for collecting returned light signals to amplify the light signals, and the blood pressure value is obtained through calculation of a corresponding algorithm. However, in practical use, due to interference of factors such as signal noise, electromagnetic interference, ambient light and the like on optical signals, blood pressure measurement data has the problems of large fluctuation and inaccuracy, and the reliability of the data is not high.
In the second aspect, no sensor or portable device for measuring cardiac output is available on the market, and only medical instruments for measuring cardiac output, such as an electromagnetic blood flow meter and a doppler color echocardiography monitor, are available. The stroke volume is the product of the heart rate and the stroke volume, which is the volume of blood pumped out per minute from the left ventricle or the right ventricle, and is an important parameter for evaluating the cardiovascular function. The data of the cardiac output can reflect the diseases of the human body to a certain extent, for example, when the cardiac output is lower than a normal value, the human body has the risk of diseases such as vascular occlusion, cerebral thrombosis and the like, so that the accurate measurement of the cardiac output has important significance.
The electromagnetic blood flow meter is based on Faraday's law of electromagnetic induction and is used in precise monitoring instrument for cardiovascular operation and invasive surgery. The electromagnetic blood flow meter consists of a flow sensor and a circuit system, and has the function of converting blood flow into corresponding voltage signals. It can measure the instantaneous or average blood flow speed in blood vessel continuously, and can also be used to measure the blood flow speed of artificial heart-lung machine, artificial kidney, etc. However, electromagnetic blood flow measurement is a traumatic measurement method, and when measuring blood flow in a blood vessel, a probe needs to be deeply inserted into the skin to be attached to the blood vessel wall, and is susceptible to external electromagnetic interference.
The Doppler color echocardiogram monitor displays the spectrogram of certain volume (SV) blood flow at a certain point in the heart or great vessel in real time by using Doppler principle and a series of electronic techniques under the condition of two-dimensional echocardiogram positioning, is a non-invasive technique capable of detecting the shunt and reflux in the heart, can measure accurately, but has large volume and high price, and is mostly used in hospitals.
In the third aspect, as the development of new crown epidemic situation gradually enters into the normalization, temperature measurement is a problem which must be faced in many places. Body temperature is one of the important criteria for judging whether a person's body is healthy, and maintaining constant body temperature is a necessary condition for ensuring normal metabolism and vital activities. Normal human body temperature is relatively constant and it maintains a dynamic balance of heat production and dissipation through the regulatory action of the thermoregulatory centers in the brain and hypothalamus. The "body temperature" described above refers to the core body temperature of the human body, which is generally constant and uniform. Clinically, the temperature refers to the average core temperature, typically represented by the temperatures of the mouth, rectum and axilla, with the rectal temperature being closest to the core body temperature of the human body. Under normal conditions, the temperature in the mouth and under the tongue is 36.3-37.2 ℃, the rectal temperature is 36.5-37.7 ℃ and the axillary temperature is 36.0-37.0 ℃.
The current temperature measurement mode mainly comprises a forehead temperature gun, a face recognition temperature measurement all-in-one machine and a temperature measurement bracelet. For the temperature measuring bracelet, the temperature measuring bracelet has great advantages due to the portability. However, the temperature of the wrist, i.e. the body surface temperature, measured by the temperature measuring bracelet is not completely equal to the actual deep temperature of the human body, so the measurement method needs to be improved.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first \ second", etc. related to the present invention are only used for distinguishing similar objects, and do not represent a specific ordering for the objects, and it should be understood that "first \ second", etc. can be interchanged in a specific order or sequence where permitted. It is to be understood that the terms first, second, etc. used herein are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.
Referring to fig. 1 and 2, the present invention provides a portable intelligent medical measuring device including a measuring main body including a blood pressure sensor 3 and a microprocessor 5.

And the median module is used for acquiring the median of a plurality of the blood pressure measured data of a first preset value acquired in a preset time period. The blood pressure sensor 3 continuously and rapidly acquires a plurality of blood pressure measured data, and at this time, the median of the blood pressure measured data group is found by taking a first preset number (for example, 100) of blood pressure measured data acquired within a short time period (for example, 1 second).
And the comparison and rejection module is used for performing difference operation on the plurality of the blood pressure measured data with the first preset value and the median respectively, and rejecting the blood pressure measured data corresponding to the blood pressure value with the absolute value of the difference exceeding the second preset value. The absolute value of the difference, i.e. the difference between the maximum value and the minimum value of the first predetermined number (e.g. 100) of measured blood pressure data (blood pressure maximum fluctuation value) generally does not exceed 10mmHg (the blood pressure maximum fluctuation value can be set according to the actual medical experiment).
And the average output module is used for performing arithmetic average calculation on the blood pressure measured data left after the elimination and outputting accurate data representing the blood pressure in the preset time period.
The part is the blood pressure accurate measurement function of the device, and the noise of the photoelectric volume pressure measurement method in the prior art caused by external factors such as signal noise, electromagnetic interference, ambient light and the like is eliminated through a designed elimination algorithm, so that the accuracy of the human blood pressure measurement is improved.
Preferably, the measurement subject may further include a heart rate sensor 1, and the heart rate sensor 1 is configured to acquire heart rate measured data.
In this case, the microprocessor 5 may further include a heartbeat output quantity calculation module capable of acquiring a heartbeat output quantity based on the blood pressure accurate data and the heart rate measured data.
The principle of measuring the cardiac output is realized as follows: the main idea of calculating the cardiac output from the pulse wave is to derive the pulse flow from the pulse pressure, so first a model of the arterial system is created that represents the quantitative relationship between pulse pressure and flow. Considering the total resistance of the human arterial system at the beginning and the end of the elastic tube, the propagation of the pulse wave in the elastic tube is influenced by the resistance at the beginning and the end, a series of wave refraction and reflection occur, and the heartbeat output is influenced.
By using the fluid related knowledge, a calculation formula of the heartbeat output can be deduced:
wherein SV is cardiac output, HR is heart rate measured data, paBlood pressure accurate data for systolic pressure, pdBlood pressure accurate data for diastolic pressure.

In this case, the microprocessor may further include an accurate body temperature calculation module, and the accurate body temperature calculation module may acquire accurate body temperature data based on the measured body temperature data and the measured room temperature data by a line fitting method.
Specifically, Δ T (the difference between the actual deep temperature and the measured temperature of the body surface) and T can be found by combining a large number of experiments with mathematical fittingAt room temperature(ambient temperature) to correct the measured temperature of the body surface. The specific way is to let the user wear the device, let it be in different environmental conditions, such as sunny day, rainy day, snowy day, night, windy or windless, etc., simulate various external conditions that the user may encounter, and then record the actual measured temperature T of the room temperature sensor 4At room temperatureThe actual body surface temperature T of the body temperature sensor 2Measured in factFurthermore, it is necessary to measure and record the actual precise temperature T of the user's deep body (e.g., the actual temperature of the deep body can be approximated by the actual temperature at the rectum) by means of an additional precise thermometerPrecision ofThereby obtaining:
△T＝Tprecision of－TMeasured in factFinally, Δ T ═ f (T) is obtainedAt room temperature) The functional relationship of (a).
In this embodiment, a straight line is adopted for fitting, and the final fitting result is:
△T＝﹣0.9402Tat room temperature+26.994, where the correlation coefficient R20.9905, indicating that the fit is linear better, can be used.
Considering that the temperature in real life and the accuracy of the sensor are both 0.1 ℃, the fitting linear equation is slightly modified to be-0.94TAt room temperature+27, the corrected exact temperature is:
Tprecision of＝TMeasured in fact+△T＝TMeasured in fact+(﹣0.94TAt room temperature+27)(℃)
Wherein, TPrecision ofAccurate body temperature data, namely actual deep temperature in the body; t isMeasured actuallyMeasured body temperature data, namely measured body temperature measured on the body surface by a body temperature sensor using the device; t isAt room temperatureIs measured room temperature data, i.e. the measured temperature of the environment (air) around the device measured using the room temperature sensor of the device.
