Abstract

A community-based remote physiological parameter monitor for old people adopts an MSP430F1612 single-chip microcomputer as the control center, and mainly completes initialization, data reading, transmitting and processing of a body temperature acquisition module, a blood oxygen acquisition module, a blood pressure acquisition module and a GPS module. The monitor transmits measured data to a remote monitor side interface through GPRS, so that attending doctors and family members can pay close attention to the physical conditions and activities of old people through the interface in real time. The monitor can simultaneously monitor the physiological data of body temperature, blood oxygen, pulse rate and blood pressure of the old people in a community; the old people can monitor own physiological parameters through the monitor, and after measuring the physiological data, the monitor remotely transmits the data to the hospital monitoring side interface or child monitoring side interfaces through GPRS; the monitor is based on community monitoring, the old people and patients with chronic diseases only need to stay in the community to complete physical examination in real time; and therefore, conversion from the medical treatment mode (symptomatic treatment) to the mode taking prevention, early-stage diagnosis and early-stage treatment as the center is promoted.

Description

Based on community remote physiological parameter monitor

Technical field

The present invention relates to a kind of based on community remote physiological parameter monitor, belong to medical instruments field.

Background technology

Along with present aged tendency of population, and lose increasing of only old man, the health supervision problem of old people causes the concern of society day by day, traditional pattern is old people oneself or accompanies hospital by children and check UP, but this pattern adds the stress of the old people of society and pecuniary burden beyond doubt, can not Timeliness coverage be accomplished for disease simultaneously, prevent in time.

Along with the development of medical monitor level, the major technique that medical monitoring industry relates to comprises bio signal algorithmic technique, parameter module technology, its technical, monitor module technology, informationization technology.Present medical monitor is generally used for the monitoring of large hospital to patient with severe symptoms, complicated operation.Now commercially also have a lot of portable medical monitor, but monitoring physiological parameter is single, and data can only allow user people's reference, hospital can not be transferred in time and measure to diagnosis and data continuity.Therefore a portable monitor can measured based on multi-physiological-parameter is designed, and in real time physiological data can be transferred to hospital monitor interface, provided the suggestion of specialty by doctor, and price can allow the low family of a lot of income accept to be very valuable and important meaning.

Detailed description of the invention

Monitor of the present invention comprises measurement of bldy temperature, blood pressure measurement, Oximetry and Gps location and GPRS data transport module.

Be described as follows by reference to the accompanying drawings:

In FIG, describing based on MSP430F1612 single-chip microcomputer is control core, and connect body temperature module, blood oxygen module, blood pressure module and GPS module, the data monitored are by GPRS long-distance transmissions.

In fig. 2, show parameter measurement flow chart, need the life parameters measured to comprise blood pressure, blood oxygen, pulse, body temperature and latitude and longitude information in design, the acquisition of these information all needs time enough to measure.The Measuring Time of each several part is substantially such: temperature measuring time 9 ~ 15S, and blood oxygen pulse measures 13 ~ 20S, and longitude and latitude measures 8 ~ 10S, blood pressure measurement 35 ~ 120S.Simultaneously in order to ensure that Power supply is stablized, during blood pressure measurement, other modules should stop measuring, because electric current reaches 600mA in blood pressure module measurement, comparatively large on other parts measurement impact, therefore independent measurement.And all the other modules are as body temperature, blood oxygen pulse and the total power consumption of GPS only 200mA, can work simultaneously, can Measuring Time be saved like this.

In figure 3, show blood pressure data flow chart of data processing, MSP430F1612 starts measuring command <STX>01 by sending; ; D7<ETX><CRGreatT .GreaT.GT opens blood pressure module, blood pressure module understands the real-time force value returned in cuff after starting working, and our final measurement result just needs diastolic pressure, systolic pressure and mean pressure, therefore real-time force value there is no need to obtain.<STX>999<ETXGrea tT.GreaT.GT<CR> can be returned measure end mark after module measurement completes; as long as the end mark of detecting, just order <STX>18 can be sent by software; ; DF <ETX><CRGreatT.G reaT.GT makes module return measurement result, and measurement result data format is <STX>Sa; Ab; Ccd; Mef; Pghijklmno; Rpqr; Tstuv; ; Wx<ETX><CRGreatT .GreaT.GT.Wherein, ghi is systolic pressure, and jkl is diastolic pressure, and mno is mean pressure, and pqr is pulse frequency.

In the diagram, show blood oxygen module data handling process, blood oxygen module is just started working after power supply electrifying, about after 10 ~ 13S, starts return measurement result.Data are 5 byte formats, each second 60 bag, the 7th is sync bit.In each packet, only have first character to save the 7th is height, therefore can in this, as judging the mark that packet is initial.

In Figure 5, show temperature data write-in program flow process, the data transmission of MLX90615 is all carry out in units of byte.Each transmission byte (sending low level after first sending a high position), then judges whether the other side has response, if there is response just to send next byte; If response, does not repeat to send this byte, if repeatedly repeat still to can not get response, then carry out error handling processing.When receiving data, each receive a byte, 8 receive and send an answer signal to the other side, then continue to receive next byte.
