Abstract
The utility model discloses a finger tip type pulse sensor, which comprises a fastening ring and a sensor, and is characterized in that: the size of the fastening ring corresponds to a finger; a clump weight is arranged in the fastening ring; the sensor is arranged on the clump weight; and the fastening ring is provided with a locking piece. As the sensor is thus designed, the structure is simple, the cost is low, the storage and carrying are convenient, the operation is light, convenient and flexible, the basic waveform of the pulse can be recorded reliably, and pulse information can be collected from a radial part and a finger part quickly and accurately.
Description
Technical field
This utility model relates to auxiliary examination apparatus technology, particularly piezoelectric type pulse image sensor.
Background technology
As everyone knows; Heart beat rhythm and pulse condition waveform not only reflect the situation of cardiac valve valve and blood vessel elasticity; Also reflected idiosoma organization metabolism and other disease condition simultaneously, traditional manual work is felt the pulse and is leaned on individual's sense of touch fully, and in fact from the sense of touch to the cognition, judge has very big ambiguity, uncertainty; Examine the subjective error that to avoid artificial palpation with scientific instrument, improve the examination precision.At present, the pick off kind of examination pulse condition is a lot: such as mechanical beam type pulse image sensor is arranged, micrometric displacement scanning just can be traced out pulse wave through drive mechanism.Piezoelectric type pulse image sensor and pressure resistance type pulse image sensor are also arranged, and they produce the signal of telecommunication through the distortion of piezoelectric effect or foil gauge and reflect that pulse beats.But these pulse image sensor structures become increasingly complex, and it is a lot of that it includes parts, and price is more expensive.The touch sensing part and the sensing rigid support of these pick offs are all huger, heavy, use inconvenient.What is more is that test the time is prone to make measurand to produce oppressed sense, and the time is long slightly, can radical response occur on measured's physiology and collects the pulse condition information less than nature.This just needs succinctly reliably easy to use, has obtained the pick off of pulse condition waveform fast.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, proposes a kind of delicate structure, and manufacturing cost is lower, manipulates simple and conveniently, can obtain the finger tip formula pulse image sensor of pulse condition waveform fast.
The purpose of this utility model realizes through following technical scheme: a kind of finger tip formula pulse image sensor; Include dead ring and induction apparatus, it is characterized in that: the dead ring size is corresponding with finger, is provided with balancing weight in the dead ring; Induction apparatus places on the balancing weight, and dead ring is equipped with locking member.Further, induction apparatus is an independent separate, and induction apparatus is the composite laminate structure, is built up by metal basal board, piezoelectric effect ceramic layer, silver contact layer trilaminate material, is made up of the plastic protective layer parcel again.And dead ring adopts the elasticity bandlet.
Such design, its advantage is: 1, simple and compact for structure, be convenient to keeping and carry, simple to operate, easy fault not; 2, contained parts are less, relative simple of structure, and cost should be cheaper, and the ratio of performance to price is excellent; 3, directly on finger, use, can not produce constriction, the testee is easy to accept and cooperate, and can collect fast and obtain pulse condition information; 4, use the comparison light and flexible, can produce record pulse condition basic waveform reliably.

The specific embodiment
Referring to Fig. 1--Fig. 3, the finger tip formula pulse image sensor of present embodiment is made up of induction apparatus 1, dead ring 2, balancing weight 3 and locking member 4.Induction apparatus 1 is to separate independently with other members, and induction apparatus 1 has the composite laminate structure, and being sandwiched in intermediary is piezoelectric effect ceramic layer 12; Lower floor is the metal basal board 13 that matees with piezoelectric effect ceramic layer 12; It is as negative pole, and the upper strata is silver contact layer 14, and it is as positive pole.Lead 5 is drawn by metal basal board 13 and silver contact layer 14 respectively, transmits the signal of telecommunication, and lead 5 adopts the softish single-core shielding line of high-quality.Metal basal board 13, piezoelectric effect ceramic layer 12, silver contact layer 14 trilaminate materials laminate, again by plastic protective layer 11 parcels.Plastic protective layer 11 can transmit pressure and isolate humidity, has high-insulativity.Dead ring 2 adopts the high resiliency bandlet to process, the big or small and finger coupling of its ring, and its effect is to guarantee that induction apparatus 1 and position to be tested realization effectively contact; And put on tested position with certain pressure; Under the effect of elasticity bandlet contractility, the counterweight briquetting 3 of metal guarantees that piezoelectric effect ceramic layer 12 and tested part realize that contacting of certain pressure arranged, and locking member 4 is passed at the two ends of elasticity bandlet; Locking member 4 has the locking spring, can compress the elasticity bandlet to guarantee that corresponding component does not produce loosening.Heart excites pulse wave; Tested position microdisplacement acts on induction apparatus 1 with the pressure form; Reach piezoelectric effect ceramic layer 12 through plastic protective layer 11 and silver contact layer 14, piezoelectric effect ceramic layer 12 produces the electric charge accumulation, is delivered to supporting pulse condition adapter through lead 5; Then convert the voltage that is proportional to pulse condition pressure to, show and record pulse condition waveform by display subsequently.
During use; Elder generation aims at induction apparatus 1 and is adjacent to the corresponding position of finger fingertip, and as shown in Figure 3, the tightness of regulating dead ring 2 elasticity bandlets makes 3 pairs of induction apparatuss 1 of balancing weight and finger tip apply certain pressure; At this moment; The pulse condition pressure that the finger tip beat pulse produces changes the electromotive force of time to time change into, through charge amplifier, just can from display read the pulse condition waveform of finger tip.Also can wear induction apparatus 1 in wrist to read oar portion pulse wave.This pick off is simply dexterous, and the trip spring locking member is carefully finely tuned the relative position of induction apparatus and finger tip, and the tightness of carefully adjusting the elasticity bandlet again just can obtain more pulse information from basic pulse condition figure.
Certainly, just list here and lifted a kind of preferred implementation, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
