Abstract
The utility model relates to a stair test pulse frequency tester, which comprises a pulse detector and a signal processor, wherein, the pulse detector is composed of an annular finger stall, a clamping device which is arranged on the annular finger stall, and a piezoelectric sensor. Due to the thin-film piezoelectric sensor, the tester has the advantages of high sensitivity, and strong anti-interference. In addition, the clamping device can ensure the close contact between a finger and the piezoelectric sensor, so that the pulse frequency of a human body can be stably and accurately tested.
Description
This utility model relates to a kind of step experiment arteries and veins analyzer frequently.
After human body was stepped on the motion of diving tower rank, arteries and veins variation frequently was an important indicator weighing human body constitution.According to national human body constitution testing standard, stepped on jumping once in per 0.5 second, move after 3 minutes, measured a human body arteries and veins every 1 minute and survey altogether frequently three times, promptly survey three arteries and veins at interval in 1,2,3 minute and (measure arteries and veins frequency half a minute) frequently at every turn.Frequently change and step on the jumping movement time according to three arteries and veins,, obtain the evaluation index of the relevant cardiac cycle of measured system body constitution quality according to the public computing formula in the world.
Therefore, step test is national human body constitution test specification project, because national human body generaI investigation large contingent, needs a large amount of step test arteries and veins analyzers (below, abbreviate " step analyzer " as) frequently for this reason.The accuracy of this series products is not good enough in the market, needs to develop a kind of novel step analyzer for this reason.
The step analyzer should have three partial functions:
Can send the accurate rhythm sound of wash rice (totally three minutes) clearly by 0.5 second beat, instruct the testee in accordance with regulations beat do stepping on of certain hour and jump motion; By 1,2,3 minute interval, accurately determine arteries and veins frequency (each half a minute); And show and store and step on jumping time, three arteries and veins frequencies, by formula calculate corresponding evaluation index simultaneously, and demonstrate result of calculation.
Therefore the step analyzer is except that the afore mentioned rules program is carried out work, wherein most critical require to make things convenient for, accurately, reliable determination human body arteries and veins frequently.It is a lot of to measure human body arteries and veins method frequently, as electric sphygmomanometer, cardioelectric monitor survey formula instrument etc. the pulse test project is arranged all.But electric sphygmomanometer need be inflated, exit.The cardioelectric monitor tester needs to be put in breast, each position of lower limb with biopotential sensor, is unsuitable for step test, and costs an arm and a leg.The step analyzer generally adopts finger to measure arteries and veins frequently at present for simplicity, domestic existing step analyzer is measured arteries and veins frequently, ST-01 type step test analyzer (Zhejiang Province Research Institute of Physical Culture product) for example, light sensitive diode and receptor alligator clamp, solid the place, can also be provided with threaded block.In addition, also can be without the bolt type structure, but the screw of clamping device is made slide bar, and screw thread is made smooth bore, this slide bar penetrates wherein, and the slide bar end is provided with spring.Like this,,, can compress fingernail, and be convenient to loading and unloading once loosening slide bar just finger can be inserted in the annular fingerstall as long as be pulled outwardly moving slide-bar.
Above-mentioned piezoelectric transducer is fixed in the bottom of annular fingerstall, and mutually opposed with this clamping device on same axis.As piezoelectric transducer itself, be to make, for example by piezoelectric membrane.This pick off can be adhered fixed on the toroidal shell of annular fingerstall with epoxy resin, and is certainly, good with the method for mechanical fixation.
During operation, to point (fingernail upwards) and insert in the annular fingerstall, rotary screw makes screw end contact with fingernail, so that finger can closely contact with piezoelectric film sensor, the output signal of piezoelectric transducer is passed to blood processor by the lead-in wire on the pick off with pulse signal.
Fig. 2 is the fundamental diagram of explanation step analyzer.In this step analyzer, adopt piezoelectric membrane to make pick off, measure the finger pulse.Finger pulsation (vibration) signal that the finger blood vessel is small by piezoelectric film sensor, converts the variable signal of voltage to.The voltage signal of this pick off, by the amplifying circuit in the pick off, the output pulse voltage signal identical after amplifying with pulse.The fluctuating signal of being exported is after further amplifying shaping, and the input single-chip microcomputer carries out numerical value to be handled, and calculates by international formula, draws the jumping time of stepping on, three arteries and veins frequencies and body constitution evaluation index.On display screen, demonstrate the jumping time of stepping on, 13 arteries and veins frequencies (30 seconds) and evaluation index at last.
Because piezoelectric film sensor is highly sensitive, strong interference immunity adopts above-mentioned clamp structure can guarantee that finger closely contacts with the piezoelectricity sensor, can measure the arteries and veins frequency of human body accurately.
