Description
Technical field
The present invention relates to blood pressure measurement technical fields, it is more particularly related to a kind of leakproof of pressure adaptive
Light intelligent health finger ring.
Background technique
The intelligent health finger ring that the present invention designs, the basic principle is that penetrating the photoelectricity volumetric blood wave of finger by measurement
(PPG) signal is decoded shape information, the basic functional principle and detection process of intelligent health finger ring and the present inventor's
Two earlier application patent documents are identical, the Publication No. CN201620618793.8 of earlier application patent and
CN201610454021.X, patent name are noninvasive continuous blood pressure measurement devices.
Finger tip PPG contains vascular health information abundant, can be used to calculate blood pressure, and can provide vascular sclerosis index,
It is used in many wearable health equipments at present.But currently there are photoelectricity continuous blood pressure measurer all deposit
In some problems, especially it is embodied in contact of the probe with finger.Finger is not a cylindrical body, but has certain radian
, especially in nail-side, if do not optimized according to the physiological models of human body, for the crowd of thick fingers, probe is pressed
Tension, the crowd thin to finger, pressure is again too light, also results in light leakage, existing soft fingerstall blood oxygen as depicted in figs. 1 and 2
Probe.Again as in Figure 3-5, even if using carrier of the soft skin silica gel 200 as light source, thick finger pressure is still resulted in
Power is excessive, and thin finger pressure is too small can also light leakage.
The size of finger tip stress is directly related with the form of volumetric blood wave, is specifically shown in the earlier application patent of the present inventor
File, earlier application patent application No. is 201710269879.3,201720431532.X, 201710269890.X,
201720431525.X。
Influenced in view of finger tip blood pressure by external pressure it is very big, it is as unknown in do not controlled external pressure or pressure, to base
For the algorithm that PPG waveform carries out blood pressure calculating, error will be very big.
The most common hardware scheme is finger-clipped/finger cot type/finger ring type on the market, is all used all groups same
A probe.
Finger-clipped is easy to use, but since the finger thickness of different crowd is different, the pressure of application is also differed, to PPG
Measurement more disadvantageously, refers to and accompanies certain subtended angle, the pressure in finger tip and finger belly part is unevenly distributed.Design master
If in order to measure blood oxygen conveniently, in view of PPG measurement is easy disturbed characteristic.
Fingerstall generally uses special silica gel material, and the pressure applied to finger sections is more uniform, in PPG measurement more
With advantage, but since the finger thickness of different crowd is different, the pressure of application is also differed, especially, according to silica gel material
The difference of hardness is also different to the pressure of finger.It is set for this purpose, proposing be adjustable the machinery of ring inner diameter size in the prior art
Set, for example publication number is CN105877018, it is a kind of it is adjustable can only ring, be CN203986452 there are also publication number, it is adjustable
Ring, but these technical solutions are directed to common ring, and regulative mode is more inflexible.
Meanwhile the probe of finger ring design is not also considered to different users' pressure different problems on the market.
Another defect existing for above-mentioned all probe designs is that probe positions can slightly change as finger tip pulse is beaten
Become, because probe material has certain elasticity, the unstability of 5mmHg or more is had in pulse beat cycles, so that final blood
Pressure measurement accuracy is extremely difficult to the 8mmHg standard passed through in the world.
Summary of the invention
It is an object of the invention to solve at least the above problems, and provide the advantages of at least will be described later.
It is a still further object of the present invention to provide a kind of light leakage intelligent health finger rings of pressure adaptive, pass through structure spy
Different design significantly reduces light leakage, and keep equal to different finger size pressure so that probe is more tight to the package of finger
Weighing apparatus, the measurement for enabling finger tip optical parameter stable under optimal pressure improve blood pressure and cardiovascular relevant parameter
The precision of measurement, and comfortable wearing, easy to use, volume only has thumbnail size, is portable intelligent blood pressure equipment.

41 lower surface 48 of chamber is deformed according to finger tip size, so that 41 lower surface 48 of cavity fits closely nail, is carried out adaptive
Cladding, finger ring is more tight to the package of finger, significantly reduces light leakage.
Meanwhile the deformation compressing of hollow out silica gel 4 provides an acquisition pressure on finger tip for finger tip, in 4 deformation of hollow out silica gel
Cheng Zhong is arranged between hollow out silica gel 4 and shell by 41 hollow out of cavity, empty as 41 cavity body structure made of silica gel of cavity
It is that hollow out is arranged between 41 lower surface 48 of chamber and shell, in measurement, the cavity 41 of hollow out silica gel 4 can effectively absorb finger tip
Size it is different and caused by pressure gap, preventing from squeezing silica gel causes stress excessive, stablizes the pressure value to finger tip, so that finger
In the state of pressure stabilization.
Finger tip is contacted with hollow out silica gel 4, so that finger is under optimum pressure, setting is 50- in optimum pressure value
70mmHg can be obtained blood pressure readings and cardio-vascular parameters for 10 seconds or so, realize quickly accurate data acquisition.Simultaneously as
Finger ring outer layer is hard material, and the relative size of hollow out silica gel 4 is smaller, and deformation is little, so capableing of the application institute of stable and uniform
Need pressure.
In specific embodiment, the distance between 41 lower surface of cavity and 311 upper surface of platform 0.9cm, the cavity
The thickness of 41 lateral walls is in 1.0mm, and the width of the cavity 41 is 2.5cm, length position 3.0cm, 41 side wall 44 of cavity
Height is in 1.2cm.The pressure value on different size finger tips is acquired, 50-60mmHg is in, it can be seen that, finger ring of the invention
It is contacted by finger tip with hollow out silica gel 4, so that the pressure value on various sizes of finger tip is stablized under optimal acquisition pressure value, is surveyed
It is highly stable during amount, so that the PPG signal measured on this basis has very high accuracy and repeatability, Jin Erti
Rise the precision of blood pressure and cardio-vascular parameters based on PPG.
And traditional fingerstall is used, pressure limit be easy to cause large error in 30-90mmHg, and has light leakage interference.
From the above mentioned, when carrying out signal acquisition to finger tip, carry out the pressure value on finger tip by hollow out silica gel 4
Adaptive adjustment, so that the measurement that finger tip optical parameter can be stable under optimal pressure, improves measurement accuracy, simultaneously
Suitable for different users.
Specifically, the present invention optimizes the carrier structure of light source, so that finger tip pressure is in optimal value, and measured
It is highly stable in journey, so that the PPG signal measured on this basis has very high accuracy and repeatability, and then promote base
In the blood pressure of PPG and the precision of cardio-vascular parameters.Meanwhile it being suitable for the people different from finger tip size and using, and finger tip pressure is steady
It is fixed；Also, the present invention is the intelligent ring device of pressure controllable, and hardware cost and existing high-grade home care sphygmomanometer maintain an equal level, volume
But only have thumbnail size, can be carried around, market potential is huge.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
