Description
Technical field
The present invention relates to rhythm of the heart detection technique field, specially a kind of intelligent rhythm of the heart detecting system of accurate quick adjustable
And method.
Background technology
In the late two decades, people's living standard is greatly improved, and science and technology also has a great progress, but section
The progress of skill also brings many bad social phenomenons；In order to ensure daily nutrition and energy supply, people must take the photograph daily
Enter substantial amounts of vegetables, meat and egg food, but vegetables, meat and egg food in the market has 90 percent
Nine are obtained by way of quickly cultivating, and businessman can use ripener or hormone to shorten the processing maturation period of food to obtain
Maximum commercial interest；The food that present people eat has a larger potential safety hazard, and thing followed disease is also increasingly
Many, a series of incidence of disease of diseases of hypertension, high fat of blood, diabetes, heart infarction etc. is also greatly increased, and therefore, people also get over
Carry out the topic of more extensive concern health, determine that two healthy key factors include timing prevention detection and good drink
Habits and customs are eaten, wherein timing prevention detection refers to that people regularly will be checked various body organs comprehensively, play pre-
Anti- effect, itself diet and habits and customs etc. can be also adjusted at any time according to inspection result.
At present, it is hospital that people, which do timing prevention detection (i.e. physical examination), and detection knot is obtained by modes such as chemical examination, film makings
Really, but with the very fast increase of Chinese population radix, there is overstaffed phenomenon in each hospital, what people stood in the queue to register
Time averagely needs 2-3 hour, goes to wait each item detection to include blood count, film making etc. afterwards to each corresponding section office, etc.
Depending on time of the time treated according to queuing, by rough estimates, the time of people's testing result from standing in the queue to register to taking
For 2-5 days, detection cycle was extremely long, and people must arrive hospital and be checked that detection process is excessively cumbersome, and the duration is long, and
Taking testing result needs the time waited longer, is detecting this period for taking testing result, the psychology of people
Put upon the full stretch and uneasy；Therefore, in order to solve the above problems, a kind of rapid detection apparatus equipment, the detector have been invented
Device equipment includes detection sensor and wave filter, and detection sensor detects each organ of human body, exemplified by detecting the rhythm of the heart, the inspection
Sensor is surveyed by detecting that heart rate forms periodic waveform signal, then device filtering after filtering, the instrument and equipment is according to filtering
The rhythm signal contrast obtained afterwards judges whether heart whether there is obvious disease states, and the instrument and equipment is easy to the quick and convenient inspection of people
Various body organs are surveyed, then hospital can be screened by its testing result people and do the project that emphasis is detected, secondary-confirmation is carried out,
Effectively shorten the cycle time of detection；But applicant has found that it is also present much during the use of this kind of detecting instrument
Shortcoming, because the frequency filtering of the detecting instrument median filter is fixed, therefore the wave filter can not be effectively to detecting
Periodic waveform signal be filtered, the testing result reliability finally given is extremely low, and the accuracy of detection of the detecting instrument is extremely low,
The testing result of this reliability extreme difference can pass to the information of gauger's mistake, have a strong impact on gauger to its healthy feelings
The judgement of condition, when serious, can delay the golden hour of gauger, extremely serious consequence be caused, to gauger and seller
Huge loss can be caused.
