Due to the adoption of the isolating amplifier (6), the utility model can operate under a worse condition for ensuring the safety of subjects.
Description
This utility model relates to a kind of medical diagnosis instrument, relates to a kind of smart instrumentation traditional Chinese medical science medical diagnosis on disease, that adopt luo-connecting point position, single chip microcomputer measurement human body footpath bioelectric potential that is applicable to or rather.
Theory of Chinese medical science thinks that the disease of human body can diagnose by footpath network and acupuncture point, and the resistance, the current potential that also extensively adopt electronic technology to measure human acupoint in the modern biomedical practice wait to be diagnosed.Because potentiometry does not need to inject any electric current to human body in measurement, thereby disturb little to human body footpath network.This footpath network information measurement instrument generally is made of following parts: (1) many groups nonpolarizable electrode in order to guiding human's collateral channels and acupoints bioelectric potential, when skin contacts with electrode, makes the additional electrical position influence minimum of generation; (2) organize preamplifiers more, generally adopt the direct current differential amplifier of high input impedance, high cmrr, to obtain the unidirectional current place value in cave, accurate human body footpath; (3) modulus (A/D) changer is the digital signal that computer can be discerned with cave, the human body footpath bioelectric potential signal transition of amplifying; (4) computer, by digital-to-analogue (D/A) changer and the switch motion of many group relaies of control relay circuit sequential control, gather the potential data at people's body surface acupuncture point that multi-group electrode records, finally print measurement data and show the change trend curve of current potential, as the index that diagnoses the illness.
Owing to adopt microcomputer, organize nonpolarizable electrode, many group relaies switch more, organize preamplifier more, gather the also bio electricity data at handler's body surface acupuncture point simultaneously, make whole analyser seem huge, be unfavorable in the on-the-spot use of medical treatment, and when measuring instrument does not have reliable ground, cause electric leakage easily, the experimenter is constituted potential electric shock threaten.
One of the purpose of this utility model is to adopt one group of nonpolarizable electrode, a group relay switch and one group of preamplifier, adopt river volume language and the very little single-chip microcomputer of volume to be installed in diagnostic apparatus inside, make it to become miniaturization, intelligentized diagnosis instrument, improve reliability, reduced simultaneously cost again, the bioelectric potential in single-chip microcomputer elder generation each cave, footpath of point-to-point measurement is stored in the random memory ram, unifies to carry out date processing then and provides diagnostic result.
Two of the purpose of this utility model is to solve because electric main is responded to and the electric shock that the experimenter causes is threatened problem, between preamplifier and single-chip microcomputer and electric current of voltage regulation, increase the isolation utmost point of forming by isolated amplifier, DC converter, to guarantee the experimenter's personal safety, even the earth-free line of instrument, the experimenter does not have Danger Electric shock risk yet, and can reduce the electrical interference of 50HZ city.
This utility model all adopts the commercialization finished product of standard except that preamplifier, be 8031 as single chip microcomputer, and the double integration A/D changer is M14433, and integrated regulator is that 7805 DC converters are 5D1540, and isolated amplifier is A01.
Describe principle of the present utility model and enforcement in detail below in conjunction with accompanying drawing.
Accompanying drawing 1, enforcement general diagram of the present utility model
Accompanying drawing 2, this utility model preamplifier electrical schematic diagram
Accompanying drawing 3, each component configuration structure chart of this utility model
Accompanying drawing 1 is an enforcement general diagram of the present utility model.A pair of nonpolarizable electrode 1 is placed on tested people's the acupuncture point, one of them is as fixed electrode, place on the special acupuncture point of body surface, another places on the 12 arteries and veins caves, positive footpath of the human body left and right sides respectively as float electrode, draw potential difference between two acupuncture points respectively by this counter electrode, A places human body ankle position for the human body common point, relay switch 2 is subjected to single-chip microcomputer 5 controls by input and output I/O mouth, when single-chip microcomputer 5 sends the data acquisition instruction, be in the relay contact adhesive of off-state at ordinary times, potential difference signal is sent into preamplifier 3 by this contact, in isolated amplifier 6 and the biproduct typing A/D changer 4, the digital signal that single-chip microcomputer 5 can discern is amplified and converted to faint analogue signal and be stored among the RAM, relay switch 2 disconnects, and finishes once sampling.After treating that the doctor is displaced to float electrode on the new acupuncture point, repeat said process again, finish the potential measurement of whole test points after, 5 pairs of full memory date processing of single-chip microcomputer are by the standard parallel interface, by small-sized dot matrix printer 9 printing test results.The single supply that DC converter 7 provides regulated power supply 8 is transformed to unsteady dual power supply and uses for preamplifier 3.Regulated power supply 8 is also to single-chip microcomputer 5, A/D changer 4 and isolated amplifier 6 power supplies.
The function of isolated amplifier is earlier the direct current signal of importing to be modulated into AC signal, is coupled to output stage through the small-sized magnetic ring transformer of inside modules, is reduced into direct current signal through demodulation, filtering again.Because the interelectrode capacity of small-sized magnetic ring transformer is very little, thereby realize the good isolation between output stage and input stage.Isolated amplifier 6 adopts commercialization modules A 01 in this utility model, isolates electric capacity between its input and output less than 10PF, withstand voltage 2KV, operating voltage range ± 10V, working power+15V is under the above-mentioned parameter condition, the induced voltage of input is extremely low, has guaranteed experimenter's personal safety.
Accompanying drawing 2 is this utility model preamplifier electrical schematic diagram.Preamplifier 3 is the direct current differential amplifier of high input impedance, high cmrr.The first order: dual operational amplifier A
1, adopt the two integrated transporting dischargings of JFET type high input impedance, be encapsulated in the same shell, have similar temperature conditions, again all as the high input impedance input stage of unit gain, make positive and negative differential wave have close amplification condition, input impedance can reach 10
