Description
Technical field
The invention belongs to the technical field of electronic equipment, more particularly to a kind of automatic inflation type pulse condition detection device.
Background technology
Social development is rapid now, and people's live and work rhythm is all quickly so that and the life stress of people is increasing,
Body is easily accessible inferior health or morbid state.The traditional Chinese medical science is raised the body in sub-health state in health, is had a lot
Effective method.The traditional Chinese medical science has long history, is even more to take the course of its own in the world.Diagnosis by feeling the pulse is that the traditional Chinese medical science is hoped, hears, asks, cut
Important link in " four methods of diagnosis ", is one of marrow of the traditional Chinese medical science, is a kind of embodiment of tcm diagnosis general principle " in carrying outside department ".In
Medical science thinks that lesion occurs for viscera qi and blood, and blood vessels operation will be affected, and pulse condition is just changed, therefore diagnosis by feeling the pulse is being faced
The advance and retreat prognosis of deducibility disease on bed, objective basis is provided for the treatment of disease.Each from ancient times to the present name doctor accumulates for diagnosis by feeling the pulse
Abundant Academic Experience, but diagnosis by feeling the pulse is all to determine the state of an illness by doctor's subjective judgement.This causes diagnosis by feeling the pulse result to disease description
Accuracy, reproducibility and uniformity be under suspicion.How with objective scientific instrument, the function of diagnosis by feeling the pulse is explained with numeral
It is clear, it is always the target that people make great efforts.Correlative study is expanded for this numerous scientific worker worldwide, with
The developing of epoch, the progress of science and technology, pulse-taking instrument arise at the historic moment.
Since the fifties in last century, with the fast development of electronic technology, many experts both at home and abroad, which just contemplate, passes through profit
With modern science and technology, develop can be used for pulse wave spectrum it is more accurate, objectify and intelligentized pulse-taking instrument.With a variety of surveys
Examination technology and method, it is directed to pulse wave spectrum research, it is expected the ways and means with modern science, the sensation under doctor is referred to turns
Change the data that can be analyzed using modern science and technology means into, and gathered and shown, so as to change that
The situation of subjective, abstract " know clearly in the heart, refer to lower hardly possible bright ".It is theoretical according to pulse wave spectrum, carry out the collection of pulse condition multidimensional information
Analyzed with pulse condition information, objective basis can be provided for the diagnosis and early detection of some clinical common major diseases.Publication No.
CN104905771A Chinese patent " electronics pulse-taking instrument " is passed with the immediate prior art of the present invention, the patent utilization pressure
Sensor gathers the cun,guan,chi signal of patient, recycles signal amplifier and A/D converter that the signal of collection is amplified and changed
Computer system is sent into data signal, is compared with the pulse condition collection of illustrative plates stored in computer system.The patent structure is simple,
Pulse signal is converted into electric signal and digitized so that doctor can carry out quantitative study to pulse signal, and avoid
The influence of subjective factor when different doctors feel the pulse to same pulse condition.
But also be present shortcomings in the existing diagnosis by feeling the pulse technology including CN104905771A, be mainly reflected in following
Aspect：1st, the pulse signal of pressure sensor collection is defeated in special ultra-weak electronic signal, and existing diagnosis by feeling the pulse system is using common
Amplifier easily produce distortion when being amplified to it；2nd, the output impedance of pressure sensor is generally large, and with pressure
Transforming impedance can change, and common voltage amplifier (such as in-phase proportion amplifier, anti-phase proportional amplifier etc.)
Input impedance be difficult to it is matched, so as to influence the normal work of pressure sensor；3rd, useful signal of the ambient noise to collection
Have a great influence, such as can not effectively suppress, then the waveform finally given can be made to have serious distortion, it is impossible to the original arteries and veins of actual response
As；4th, pressure sensor is typically influenced by environmental temperature, at different ambient temperatures, past to the collection result of same pulse condition
It is past to have very big skew so that collection result does not have uniformity.
The above defect all carrys out many inconvenience to follow-up diagnosis, analytic band, it is easy to causes mistaken diagnosis, therefore existing arteries and veins
Examine equipment also need to it is further perfect.
