Abstract
There is provided a bedside and portable dual purpose low power life monitor with parameters and waveform display. It can monitor the breathe wave and the first channel of electrocardio-signal received from chest electrode, the second channel of electrocardio-signal from another chest electrode, the pulse, blood pressure and blood oxygen signals from skin optic detector, and human body temperature from temperature sensor. Both the waveforms and data can be displayed on a liquid crystal displayer.
Description
The present invention relates to a kind of instrument of miniature monitoring human life, belong to technical field of medical instruments.
Life monitor is a kind ofly can monitor parameter instruments such as patient's electrocardio, breathing, blood pressure simultaneously.Existing monitor can be divided into two classes: a class is the bedside type, Alternating Current Power Supply, and the cathode-ray tube display figure, thereby volume is big, power consumption is many, carry inconvenience, is not suitable for the monitoring of non-sickbed patients; Another kind of is that the pocket volume is less, adopts digital display device, can only display digit and English letter, and also function is less, can only monitor 2,3 parameters at the most.
Purpose of the present invention will provide the life monitor of a kind of bedside portable dual-purpose type, low-power consumption, the multiple parameter of monitoring, pictorial display exactly.
The present invention is made of respiration channel, electrocardiac channel, pulse wave passage, temperature channel, multi-functional microprocessor, RAM memorizer, display, contacts with overseas parties mouth, clock generator and squealer in order to achieve the above object.The respiration channel operation principle is: high frequency generator control constant-current source sends on a pair of chest electrode that the high frequency constant current is added in human body, the breast resistance of human body changes with the variation of breathing, this variation produces respiratory wave and sends into A/D converter after data amplifier, high pass filter, linear detector, low pass filter amplification detection, can detect breathing.The electrocardiac channel operation principle is: signal produces the electrocardio ripple and sends into A/D converter on a pair of chest electrode behind data amplifier, band filter, can detect electrocardio.Pulse wave passage operation principle is: with pulse signal driven for emitting lights diode irradiation skin, survey the reflected light or the perspective light of skin with phototriode, light emitting diode and phototriode constitute the skin photodetector together, when veins beneath the skin shrinks and expand, reflected light or perspective light also change thereupon, the output of skin photodetector produces pulse wave and sends into A/D converter after high pass filter, linear detector, low pass filter amplification detection, can detect blood pressure, pulse and blood oxygen.Temperature channel by the temperature of temperature sensor human body after send into A/D converter behind the amplifier.A core that contains the multi-functional microprocessor of A/D converter, I square C serial port, ROM and CPU as this instrument is used for calculating, communicates by letter, discerns and control.The RAM memorizer links to each other with microprocessor by bus, is used to store data.Display adopts the figure form crystal display also to be connected on the bus, can display waveform, data.A general input/output port of microprocessor links to each other with the contacts with overseas parties mouth, be used for dateout and with other compunications.The I of microprocessor square of C serial port links to each other with clock generator, for instrument provides the time.The squealer operation principle is: draw the sound that a line produces to piezoelectric patches driver drives piezoelectric patches by another general input/output port interface of microprocessor, sound is used for pointing out, reports to the police and transmits information with phone.All integrated circuits all adopt the CMOS integrated circuit.
The present invention is owing to use the multi-functional microprocessor as one of collection, CMOS integrated circuit, figure form crystal display, piezoelectric patches so can reduce volume and power consumption, and can detect breathing, electrocardio, blood pressure, blood oxygen, pulse and the multiple parameter of temperature, and have figure, data show function.
Accompanying drawing is a kind of concrete structure figure of the present invention.
A microprocessor 19 that contains A/D converter, I square C serial port, ROM and CPU is core.High frequency generator 3 control constant-current sources 2 send the high frequency constant current and are added on the chest electrode interface 1.Signal by 1 input of chest electrode interface is divided into two-way behind data amplifier 5; One the tunnel produces respiratory wave after high pass filter 6, linear detector 7, low pass filter 8 amplification detection sends into A/D converter input line 20; Another road produces the electrocardio ripple and sends into A/D converter input line 20 behind band filter 4, form first via electrocardiosignal.So only use a pair of chest electrode of chest electrode interface 1 just can finish one tunnel breathing and one road cardiac electrical input, a breathing electro cardiographic hybrid channel is promptly arranged.Through data amplifier 10, band filter 11 after, produce the electrocardio ripple by the signal of another chest electrode interface 9 inputs and send into A/D converter and import line 20, form the second tunnel electrocardiosignal.The light emitting diode that pulse generator 12 signals drive in the skin photodetector 14 through driver 13,14 outputs of skin photodetector produce pulse wave and send into A/D converter input line 20 after high pass filter 15, linear detector 16, low pass filter 17 amplification detection.The output of temperature sensor 18 produces temperature signal and sends into A/D converter input line 20 behind amplifier 19.RAM memorizer 30 links to each other with microprocessor 21 by bus 29.Figure form crystal display 31 also is connected on the bus 29.The lead-in wire 24 of a general input/output port of microprocessor 21 links to each other with contacts with overseas parties mouth 25.The lead-in wire 22 of the I of microprocessor 21 square of C serial port links to each other with clock generator 23.Draw a line 26 to piezoelectric patches driver 27 by another general input/output port interface of microprocessor 21 and drive piezoelectric patches 28.All integrated circuits all adopt the CMOS integrated circuit.
Microprocessor 21 is the 8XC552 series monolithic, and high frequency generator 3 frequencies are 10～50KHz, and constant-current source 2 sends 0.02～5mA that the high frequency constant current is, figure form crystal display 31 is a T6963 series control type, and clock generator 23 adopts PCF8583.
