Description

The size intelligent healthcare instrument

Technical field

This utility model relates to a kind of brand-new medical apparatus, specifically a kind of size intelligent healthcare instrument.

Background technology

Along with the development of Chinese national economy, people are improving constantly the health concerns degree.Obtained effective control such as specific infectious disease such as dysentery, the plagues, principal disease also becomes chronic infectious disease from acute infectious disease gradually.Such as the control of diseases such as hypertension, heart disease, diabetes and cancer and more back rehabilitation, become the subject matter that needs solution.World Health Organization's estimation, the sickness rate of chronic disease presents fast rise trend, expects the year two thousand twenty, and chronic disease will become the main cause of human anergy (Disability).Have the size intelligent healthcare instrument, people can judge children under guardianship person's health according to data oneself.For the user who just recovers from a dangerous illness, can observe operation and therapeutic effect; Just can be found in early days that for chronic disease the doctor takes corresponding medical measure to solve; For the demblee form disease, the guardian can take some measures of saving oneself, simultaneously also can pass through telecommunication, tutorial condition notification is arrived the doctor of hospital to the doctor of community even notice to tutorial family members and notice, this moment, the doctor also can give guardian or its family members simply emergent doctor's advice by network, the guardian can be accessed diagnose timely and gave treatment to.

China starts late to the research of health monitoring system, monitor is the structure of " PC+ monitor ", uses 8 chip microcontroller more, can not break away from PC work, this has restricted its development and popularization to a certain extent, and remains in gap at special kinds and some performance indications; Aspect shell design and processes, main hardware structure and functional parameter, reached or near external advanced product level, can satisfy general clinical needs.But, do not develop portable size intelligent healthcare instrument so far.The external research of having carried out this field early, and obtained a lot of outstanding achievements.But external product all is to adopt the acoustical coupling mode to be modulated to audio frequency to use the telephone wire transmission, and the physiological parameter module connects terminal by serial ports, and entire equipment is expensive, the national conditions of incompatibility China.Equally, they do not develop the little health intelligent monitor of volume now yet.

Summary of the invention

Description of drawings

Accompanying drawing is global design conceptual scheme of the present utility model.

Fig. 1 is size intelligent healthcare instrument sense terminals scheme MCU-1, and Fig. 2 is size intelligent healthcare instrument sense terminals scheme MCU-2, and Fig. 3 is the hardware system The general frame, and Fig. 4 is physiology signal acquiring board master chip circuit, and Fig. 5 is six road A/D channel allocation table.

The specific embodiment

With reference to accompanying drawing this utility model is done following concrete detailed description:

As accompanying drawing 1, shown in 2, native system is made up of six parts such as blood pressure, hear sounds, pulse, electrocardio, temperature sensor, analog signal processing part, Digital Signal Processing part, data communication part, phonic warning and LCD demonstrations, except finishing blood pressure, body temperature, pulse, electrocardio, hear sounds are detected the monitoring, also have functions such as phonic warning, Bluetooth transmission, data storage.This system can be to real-time collection and the processing of physiological parameter, and with physiological parameter and the undistorted hospital server that is sent to of result.Data storage and demonstration that hospital server sends the intelligent terminal are for the further analyzing and diagnosing of doctor.The doctor can send to the intelligent terminal by network with diagnostic result and suggestion.Diagnostic result can show in terminal, patients or guardianship reference.The multiparameter detection system is made up of wrist strap and the monitor box that is attached on the wrist strap, adopts dual micro processor, and MCU-2 finishes every vital signs signals collecting and analysis, and MCU-1 finishes man-machine interaction and data communication.

As shown in Figure 3, the main frame MPU of native system adopts Samsung company to produce the S3C2410 processor, the S3C2410 processor is ARM920T kernel CPU, the frequency of high support reaches 200M, and has a MMU virtual memory management unit, can move built-in Linux easily, have peripheral hardware in the abundant sheet simultaneously, have very high cost performance.Fig. 2-3 is the hardware system The general frame, because the S3C2410 chip internal has comprised driving governors such as UART, LCD, network interface card, SDRAM, FLASH, so just simplified the peripheral circuit of main frame greatly, and capture card has utilized A/D integrated on the ATmega8 single-chip microcomputer to gather and serial communication, as long as designed the circuit design that the regulating physiological signals circuit just can be finished capture card, overall circuit is succinct, can realize the miniaturization requirement of monitor.When developing work, the JATG emulator UnetlCE that S3CEB2410 development board and its is supporting combines and develops, and after having write application program, with Unet ICE executable file is downloaded on the development board and to debug.Ought finish procedure development work at last, with Unet ICE with program Solidification in the NAND Flash of development board.

[0022] as shown in Figure 4, though also extended out 8 passage ADC interfaces of S3C2410 chip internal on the development board, but owing in the design, adopted touch screen, it has taken the two-way of ADC in the CPU, if also will be with the collection A/D passage of other 6 passage as physiologic information, will be very complicated during software design in the later stage.Because this 8 road A/D is time-sharing multiplex, when we carry out the A/D conversion at full speed, must consider the timeslice of ADC is told a part to keep the response of touch screen, the performance of entire system is brought very big influence, and conflict is especially obvious when multichannel is gathered simultaneously.On the basis of ARM development board, we have developed the serial data collection plate based on the ATmega8 single-chip microcomputer again for this reason, are specifically designed to the collection of front end physiological signal, and communicate by serial ports and development board.The ADC that has comprised 8 road 10bit (ADC4 and ADC5 are 8bit) in the ATmega8, be 65us-260us conversion time, the sample frequency that designs in native system is 200Hz, so the ADC in the ATmega8 can satisfy requirement on the sampling time, thereby can simplify the circuit design of collection plate.

The electromagnetic interference that the inside and outside digital circuit of Tmega8 single-chip microcomputer produces will be simulated ground and digitally separate with 0 ohmage, simultaneously AVCC will be connected with VCC with the LC network that C8 forms by using L1, and analog power AVCC and word power supply VCC are isolated.Because will select AVCC in this circuit is reference power source, therefore AREF is drawn the angle by capacitor C 12 ground connection, to avoid interference.In order to increase availability, when moving, program plays indicative function at direct external two LED lamps on the ATmega8.The A/D channel allocation table of each analog input during Fig. 5 designs for this reason.

Enforcement recited above only is that preferred implementation of the present utility model is described; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from this utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that this utility model is asked for protection all has been documented in claims.
