Description
Technical field
The present invention relates to blood pressure measuring device technical field, it is more particularly related to a kind of conjunction of pressure controllable
Body formula intelligent health finger ring.
Background technology
The intelligent health finger ring that the present invention is designed, its general principle is the photoelectricity volumetric blood ripple that finger is penetrated by measurement
（PPG）Signal, is decoded to 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 is noninvasive continuous blood pressure measurement device.
Finger tip PPG contains abundant vascular health information, can be for calculating blood pressure, and can provide vascular sclerosis index,
It is used at present in many wearable healthy equipment.But the photoelectricity continuous blood pressure measurer that currently there are all is deposited
In some problems, especially it is embodied in mechanically stressed design, is optimized not according to the physiological models of human body.It is inappropriate by
Power design not only causes signal easily to be influenceed by moving, and can also introduce venous pulse signal, the precision for the measurement that reduces blood pressure.
The size of finger tip stress is directly related with the form of volumetric blood ripple, is in particular in：
1st, PPG dynamic amplitudes（AC parts）Increase first with pressure and gradually increase, start to increase with pressure in some peak
Plus and be gradually reduced, it is approximate with the pulse wave envelope of oscillographic method；
2nd, PPG waveforms can be also altered in steps with pressure increase, and when pressure increases to a certain degree, subwave can become more
To be obvious, as pressure further increases, subwave is gradually crushed, and waveform starts distortion, as shown in Figure 1；
3rd, under different contacts, finger tip PPG signals be from the degree of correlation of blood pressure it is different, as shown in Figure 2；
4th, blood pressure is generally referred to as the diastolic pressure and systolic pressure of artery, ideally, and ambient pressure should be able to suppress vein
Beating so that beat signals are only from artery.But if ambient pressure is too small, vein still has faint fight
Dynamic, superposition in the output signal, can be interfered to blood pressure measurement.
In view of finger tip blood pressure is influenceed very big by external pressure, if do not controlled external pressure, or pressure is unknown, to base
For the algorithm that PPG waveforms carry out blood pressure calculating, error will be very big.
Most common hardware scheme is finger-clipped/finger cot type/finger ring type on the market, to all groups all using same
Individual probe.
Finger-clipped is easy to use, but be due to different crowd finger thickness it is different, the pressure of application also, to PPG
Measurement more disadvantageously, refers to and accompanies certain subtended angle, the pressure in finger tip and finger belly part is pockety.Design master
If in order to measure, blood oxygen is convenient, and easily disturbed characteristic is not measured in view of PPG.
Fingerstall typically uses special silica gel material, and the pressure applied to finger sections is more uniform, in PPG measurements more
With advantage, but be due to different crowd finger thickness it is different, the pressure of application also, especially, according to silica gel material
The difference of soft durometer is also different to the pressure of finger.Therefore, the machinery for proposing energy regulation ring internal diameter size in the prior art is set
Put, such as publication number is CN105877018, it is a kind of it is adjustable can only ring, also publication number is CN203986452, adjustable
Ring, but these technical schemes are directed to common ring, and regulative mode is more inflexible.
Meanwhile, not the problem of probe of finger ring design does not consider different to different users' pressure yet on the market.
Another defect that above-mentioned all probe designs are present is that probe positions can slightly change as finger tip pulse is beaten
Become, because probe material has certain elasticity, more than 5mmHg unstability is had in pulse beat cycles so that final blood
Pressure measurement accuracy is extremely difficult to the 8mmHg standards passed through in the world.
The content of the invention
