Abstract
A kind of optically focused servicing unit for making simple heart rate sensor measure precision, its apparatus system is the device of the half opening being made of silicone-hydrogel material.Apparatus system by two-way silicone-hydrogel convex lens group into.Because heart rate sensor would generally be measured when using from photoplethymograph.Using optical principle, heart rate is calculated after treatment.The servicing unit that light gathers is made using silicone-hydrogel design of material, heart rate sensor is wrapped up, using the concentrating light principles of convex lens, measurement result is avoided gross error.
Description
Technical field
Patent of the present invention is related to a kind of health monitoring device, more particularly to one kind surveys simple photoelectricity heart rate sensor
Measure the optically focused servicing unit of result precision.
Background technology
With expanding economy, people's living standard is increasingly improved, and increasing people is for itself and its household's health
Attention rate improve constantly.Health problem has become focus of concern.And such as the ginseng such as " body temperature, blood pressure, pulse, heart rate "
Number is that human health status most intuitively embody, and such health parameters can be high-precision in human body surface direct measurement
The analysis of the monitoring parameters on human health status of degree has important effect.Heart rate sensor generally uses photocapacitance on the market
Area method.Why blood is presented red, because it reflects feux rouges and absorbs green glow.Heart rate sensor uses green LED lamp, coordinates
Photosensitive photoreceptor, detection random time point flows through the blood flow of finger.During heartbeat, the blood meeting of finger is flowed through
Increase, the green glow of absorption can also increase；Can then be reduced during eartbeat interval.The LED flashed by hundreds of times every second, Wo Menke
To calculate beats per minute, that is, heart rate.But when simple heart rate sensor sends green LED light, due to
Power pressing heart rate sensor can be destroyed sensor device, so we are generally at a distance by sensing heart rate
Device is shelved or gently put on finger tip.At the same time, the green LED light that heart rate sensor sends occurs that light cannot be brought to finger
Sharp surface, produces Divergent Phenomenon, makes the green glow of absorption and the feux rouges of reflection inaccurate, causes measurement result error occur.Therefore,
Prior art is needed to be further improved.
Patent of invention content
The purpose of patent of the present invention is that offer is a kind of makes the optically focused of simple photoelectricity heart rate sensor measurement result precision
Servicing unit, solves the gross error that the scattering of simple photoelectric sensor light causes.Why blood is presented red, because it is anti-
Penetrate feux rouges and absorb green glow.Heart rate sensor uses green LED lamp, coordinates photosensitive photoreceptor, detects random time point
Flow through the blood flow of finger.During heartbeat, the blood for flowing through finger can increase, and the green glow of absorption can also increase；Between heartbeat
Can then be reduced every period.The LED flashed by hundreds of times every second, we can calculate beats per minute, that is,
Heart rate.But when simple heart rate sensor sends green LED light, because firmly pressing heart rate sensor can make sensor device
Destroyed, so heart rate sensor is generally being shelved or gently put on finger tip by we at a distance.At the same time,
The green LED light that heart rate sensor sends occurs that light cannot be brought to finger tip surface, produces Divergent Phenomenon.Ring is gathered in selection
And it is wrapped in the periphery of heart rate sensor, it is ensured that heart rate sensor and servicing unit are fitted, tight.By the dress after laminating
The finger tip put down gently in the measured is put, heart rate sensor is connected with microprocessor, and send green LED light, green LED light leads to
Cross and gather ring, the operation principle using convex lens gathers light, reduce diverging, finally calculated currently using photoplethymograph
The real-time heart rate of moment the measured.
Patent of the present invention has the beneficial effect that：
1. patent structure of the present invention is simple, easy to use, it is possible to achieve the precision of heart rate sensor is measured so as to reduce
Gross error.
2. patent of the present invention can also avoid component and direct skin contact, prevent human sweat from contaminating component and cause corruption
Erosion.
Specific embodiment
1. silicone-hydrogel material is chosen, circle is shaped as, area is slightly larger than heart rate sensor, wraps heart rate sensor.
2. ring is gathered using the design of half-open mouth-shaped, both sides shape is all convex lens, realizes gathering for light.
3. heart rate sensor is connected with microprocessor, heart rate sensor sends green LED light.
4. ensure that heart rate sensor is fitted with servicing unit, tight, and gently put finger tip.
5. green LED light is gathered light by gathering ring, reduces diverging, finally calculates the heart using photoplethymograph
Rate.
