Abstract

A kind of instrument with computer human body controlled vascular blood flow graph, form by pick off, interface circuit, micro computer and application program thereof, it is characterized in that physiological mechanics phenomenon according to human vas is opened, compression process took place, form with controlled vascular blood flow graph, in conjunction with the instant inspection information of the traditional Chinese medical science, cerebral hemorrhage, cerebral thrombosis, myocardium power, the blood that goes out patient by COMPUTER CALCULATION such as supplies at situation, and as the foundation that offers patient or control, instrument is easy to use.

Description

Computer controlled vascular blood flow graph instrument

A kind of instrument with computer human body controlled vascular blood flow graph belongs to the Medical Instruments class.

The instrument of present existing human body cardiovascular function, sheerly doctor trained in Western medicine pathology principle is not entered the Chinese medicine diagnosis theory and combining, and diagnosis has certain limitation.

The instrument that the purpose of this invention is to provide a kind of diagnosis human body cardiovascular function of the combination of Chinese and Western medicine.

Principle of the present invention is to use a kind of pressure transducer, detect pulse wave from human finger, according to this waveform, calculate the various indexs relevant by computer program with the human body cardiovascular function, simultaneously, computer program also according to the tcm inspection information and the pulse-taking information of keyboard input, demonstrates diagnosis: the present situation of cerebral hemorrhage, cerebral thrombosis, myocardium power, blood confession, the foundation that offers detected person's treatment or prevent and treat.

Be described in detail embodiments of the invention below in conjunction with accompanying drawing, accompanying drawing 1 is a hardware block diagram of the present invention, 13 is the pick offs that detect pulse wave from people's finger among the figure, the 14th, and amplifier, it amplifies the pulse signal that pick off records and waveform processing, give A/D converter then and convert digital signal to, 16 is 286 micro computers, the 17th, and keyboard, the 18th, printer, the 19th, display has application program of the present invention in the micro computer 16.

Accompanying drawing 2 is human body electrocardio oscillograms, indicates Q, R, S ripple among the figure, and the present invention is according to this waveform parameter, and the index of definition cardiovascular function is: periphery pressure (promptly little-intra-arterial pressure) P=R _Max, R _MaxBe the maximum R wave amplitude that when adjusting pick off 13, records, heart pump capacity (being the output of cardiac blood) H=(R+P)/2, blood deposition condition (being whether blood is for sufficient) R=(R _60m+ R _50m+ R _40m)/3, wherein R _60m, R _50m, R _40mBe the pressure of tested finger when adjusting pick off 13 pressure when being respectively 60,50,40 millimeter of mercuries, tube wall resistance (being little blood vessel, interior resistance) Z=H-R, palmic rate F=(F _Max+ F _Min)/2, pulsation rhythm and pace of moving things C=F _Max-F _Min, perfusion is (being that the blood filling volume is sufficient) Q=Q easily _70m+ Q _60m+ Q _50mThe subscript connotation of Q as hereinbefore, blood vessel elasticity (R)/(Z)=((R)/(Z _Max)+(R)/(Z _Min))/2, blood flow viscosity (T)/(R)=((T)/(R _Max)+(T)/(R _Min))/2, myocardial contraction (T)/(F)=((T)/(F _Max)+(T)/(F _Min))/2.These indexs are by existing the program in the microcomputer memory to calculate in advance, program is also according to the information of tcm inspection input and the information of pulse wave spectrum input, judge diagnosis and calculate cerebral hemorrhage, cerebral thrombosis, myocardium power, blood by display 19 and printer 18 and state such as supply, offer the foundation of patient as treatment or control.

Accompanying drawing 3 is program flow diagrams, 1 is beginning among the figure, the 2nd, literal shows, the 3rd, input case history numbering, the 4th, check to have or not case history archive, the 5th, the case history archive storehouse, the 6th, the waveform sampling input, the 7th, distinguish the waveform input, the 8th, the tcm inspection input, this is to observe the state of an illness of being imported this patient behind the patient by the instrumentation personnel then and there by the Chinese physician, the 9th, and the pulse-taking input, it is after by the Chinese physician patient being carried out pulse-taking, patient's state of an illness of instant input instrument, the 10th, patient's age (or pregnancy period of anemia of pregnant woman) input, the 11st, diagnosis, the 12nd, deposit, printing.

Advantage of the present invention is the physiological mechanics phenomenon according to human vas is opened, compression process takes place, form with controlled vascular blood flow graph, information in conjunction with the instant observation input of the traditional Chinese medical science, calculate patient's cerebral hemorrhage, cerebral thrombus, scheming power, blood with computer and the critical days of situation, the information that maybe should note and prevent and treat safe period such as supply, belong to no wound and detect, instrument is easy to use.

Claims

1, a kind of computer controlled vascular blood flow graph instrument that is used for examining side human body cardiovascular function, it is characterized in that by pick off 13, amplifying circuit 14, A/D converter 15, micro computer 16, keyboard 17, printer 18, display 19 and computer applied algorithm 1-12 form, Q, R, S ripple and T, F parameter in the electrocardiosignal that records according to pick off are determined by computed in software: small artery internal pressure P=R _Max1, heart pump capacity H=(R+P)/2, blood supply situation R=(R _60m+ R _50m+ R _40m)/3, tube wall resistance Z=H-R, filling capacity Q=Q _70m+ Q _60m+ Q _50m1, blood vessel elasticity (R)/(Z)=((R)/(Z _Max)+(R)/(Z _Min))/2, myocardial contraction (T)/(F)=((T)/(F _Max)+(T)/(F _Min))/2 blood flow viscosity (T)/(R)=((T)/(R _Max)+(T)/(R _Min))/2, palmic rate F=(F _Max+ F _Min)/2, pulsation rhythm and pace of moving things C=F _Max-F _Min, program also according to the inspection and the input of pulse-taking information of the traditional Chinese medical science, is comprehensively judged conclusion: cerebral hemorrhage, cerebral thrombosis, myocardium power, blood deposition condition.
