Abstract

The utility model uses for the lying-in woman during the pregnancy period, which wards for the mother, before the birth, midst the birth and after the birth of the fetus, which is a wardship for a plurality of human body physiology parameter. Seven sensors send a plurality of the human body physiology signals which includes the temperature, blood pressure, pulse, cardiogram, blood oxidizing, breath and uterine contraction for the mother, the heart rate and the dynamic for the fetus or the like, which send into the mainframe of the wardship system through transmit cable. After dealing with the micro-processor, the wardship system achieves the function of detecting with synchronous in real time, the color which is showed on the same screen, picture of the display screen which is froze, physiology information and preplaced bound warning, thereby providing a safety wardship device for the mother of the pregnancy period and the fetus.

Description

The comprehensive monitor system of mother/fetus

The new shape of this practicality belongs to Medical Instruments, be mainly used between puerpera's perinatal stage, to mother, fetus antenatal, produce in and puerperal the mother and baby is carried out the monitoring of multinomial human body physiological parameter.

Have only in the market and separately mother is guarded or, need usually to place two kinds of instruments, manipulate equal inconvenience at the head of a bed separately to the monitor product of fetal monitoring.The present invention is the comprehensive one of monitoring function of two separate payments (mother and fetus), and measuring abilities such as electrocardio have been increased, realized real-time synchronous detecting, colored with the multiple physiological parameter of screen demonstration, can preset various physiologic informations simultaneously, upper lower limit value is reported to the police, for mother, the fetus of pregnant and perinatal period provides a kind of more reliable safety custody equipment.

This utility model is achieved in that mother's body temperature, blood pressure, pulse, electrocardio, blood oxygen, breathe, the fetal rhythm rate of uterine contraction pressure and fetus, multiple physiology signal such as fetal movement picks up through seven pick offs of special use, by the signal input monitor main frame of transmission cable with above-mentioned each pick off, anti-jamming circuit in the monitor main frame, high input impedance amplifier, analog digital conversion etc., processing of circuit is sent into the microprocessor that INTEL80C196+16C550 constitutes, by the program of setting, handle and the management pregnant and lying-in women, the above-mentioned multiple human body physiological parameter of fetus, on colorful display screen, demonstrate waveform and Word message, display screen also has the picture freeze function, be convenient to the physiologic information of guardianship is carried out qualitative analysis, the warning of bound can remind medical personnel in time to take emergency measures, the monitor main body also is provided with the external printer interface circuit, the real-time physiologic information of monitoring can be printed file and put on record and medical record research.Accompanying drawing one is a structural principle block diagram of the present utility model

Also be provided with following two special modules in the monitor main frame in this utility model, to reach better anti-interference effect and accurate the measurement, describe in further detail below in conjunction with accompanying drawing:

DC/DC conversion and photoelectric isolation module

Because the physiology signal of gathering is the faint signal of telecommunication, very easily be interfered, can influence the precision of test result, this DC/DC conversion and photoelectric isolation module are made up of DC/DC transducer and photoisolator, before DC/DC conversion, late-class circuit totally one power supply not, before photoelectricity is isolated, late-class circuit not altogether, further effectively improved capacity of resisting disturbance, referring now to accompanying drawing 2 its operation principle is described:

U ₁₉Be DC5DH12HV DC/DC conversion integration block, we are at U ₁₉(3) (4) foot input+5V, under the effect of lsi internal circuit, at U ₁₉(5) foot can obtain-12V output, in (7) foot acquisitions+12V output, realized that preceding late-class circuit+5V changes in the DC/DC of ± 12V.

U ₂₀Be the DC5SHVDC/DC conversion integration block, can be at its (3) (4) foot input+5V in (7) (8) foot acquisition+5V output, realized the DC/DC conversion of preceding late-class circuit+5V and+5V.

Human Physiology digital information by microprocessor 80C196 output is sent into U by JXD patch panel (1) foot of this module ₁₂(1) foot of photoisolator (TLP521-2 type) is passing through U in its (8) foot output after photoelectricity is isolated ₆Phase inverter (74HCO ₂) (9) foot input carry out anti-phasely, the signal after anti-phase is by U ₆(10) foot output, this output signal is being sent into U ₈(2) foot of photoisolator (TLP521-2 type) photoelectricity is once more isolated, and its output (8) foot passes through J ₄(6) foot of patch panel is sent into the signal input part of display, has realized the photoelectricity isolation of human digit signal between microprocessor and display.

The control information that operation keyboard sends is because J4 patch panel (4) foot is gone into U ₂₂(2) foot of photoisolator (TLP521-2 type), photoelectricity are isolated the back by U ₂₂U is being passed through in (8) foot output of integrated package ₂₃(9) foot of phase inverter (7404 type) carries out anti-phase, and the signal after anti-phase is at U ₂₃(8) foot output of integrated package, anti-phase signal is sent into U again ₁₅Photoisolator (TLP521-2 type) (2) foot, the signal after photoelectricity is isolated is by U ₁₅(8) foot output deliver to the control end of microprocessor 80C196 integrated package, realized that the photoelectricity between keyboard input signal and microprocessor is isolated.

The electrocardiosignal immunity module

Because the faint waveshape signal of electrocardiosignal figure, very easily be interfered, influence measuring accuracy, this module can suppress the interference of common-mode signal and improve input impedance, guarantee the linear amplification and the amplification of amplifier, human ecg signal is accurately sent into the microprocessor operation, accompanying drawing 3 is electrical schematic diagrams of this module, referring now to Fig. 3 its operation principle is described: four electrocardiosignaies sending here through EGC sensor are by the patch panel J of this module, and delivering to discharge voltage is the discharge tube (LP of 70V _1～4) and three grades of capacitance-resistance filter (C _1～15, R _1～12), this wave filter can filter high-frequency interferencing signal, electrocardiosignal behind the filter filtering is sent into (5) (6) foot, (3) (2) foot, (10) (9) foot, (12) (13) foot of LF444 type integrated package respectively, the function of this integrated package is to form 1: 1 comparator, the signal of its outfan (7) (1) (8) (14) foot has improved input impedance and has suppressed common-mode signal and disturb, and has guaranteed that monitor shows the precision of electrocardiosignal.
