Description
Technical field
The present invention relates to human health monitoring arts, in particular to a kind of system based on multi-parameters sampling.
Background technique
With the development of social economy and the raising of living standards of the people, human health is guarded increasingly by the pass of people
Note.Demand with scientific and technical in recent years progress and health care settings to portability, occurs more and more in the market
The healthy bracelet of multiple types, the wearable devices such as smartwatch.This wearable device is convenient for carrying, and cruise duration is long, can be with
Human health status is continued to monitor, provides most timely healthy early warning service for the people.
It is the window for prying through in vivo functionality variation since pulse condition can transmit the physiological and pathological information of body each section, it can be with
Important evidence is provided to diagnose the illness, so the monitoring of pulse is particularly significant in the various characterization parameters of human health.It grasps
Pulse condition can find the state of an illness early, take control measure in time.The favourable turn of the state of an illness, Bu Huizao can be grasped comprehensively in diagnosis and treatment process
At blindness medication, so that influencing therapeutic effect.In addition to pulse, be also richly stored with physiological and pathological information in human body blood oxygen,
A large amount of clinic measured result confirmation, the height of blood oxygen and the feature of pulse and Cardial or cerebral vascular diseases close relation.Blood oxygen
The integrated information of form that the height and pulse wave of saturation degree show, intensity, rate etc. is really to a great extent
Reflect many physiology and pathological characters of the human body heart, cerebrovascular system.In addition, can be obtained largely to continuing to monitor for body temperature
Temperature data, and characterization various disease, the body temperature value of different physiological status are obtained by scientific analysis, to help to monitor people
Body health status.
The existing healthy bracelet in market only provides the relatively simple function such as the real-time heart rate of record user, movement step counting mostly

Signal, by temperature data selector, select it is therein be sent into kernel control chip MCU 7 all the way, 7 simple process of MCU it
Afterwards, output is to wireless transmitter module 8.
Wireless transmitter module 8 be bluetooth or WIFI module, MCU 7 by the signal of treated three kinds of sensors serially
Be sent into wireless transmitter module 8, after the bluetooth or WIFI at mobile phone or the end PC are connected thereto, by real-time data transmission to mobile phone or
The end PC carries out data processing, analysis, further, provides the health status of user.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
1, the present invention is saturated the body temperature and blood oxygen of pulse wave signal, cun, guan and chi, three places at the wrist where the pulse is usually taken position at human vas bounce position
Degree multiple parameters are acquired, and several physiological parameters are associated, feed back user in time when there is fortuitous event
Information simultaneously effectively controls, and then achievees the purpose that monitoring, provides more fully health supervision service for user；
2, the present invention uses the pressure sensor of array, can acquire the arteries and veins of human body wrist " very little ", "Off", " ruler " simultaneously
It fights wave signal, provides data supporting for the method for feeling the pulse of three body parts and nine pulse taking sites, can effectively provide the pulse condition information of user, and to arteries and veins
As time domain, frequency domain information are interpreted, the physical condition for grasping oneself immediately is enabled users to, to there is good usage experience；
3, the present invention uses the MEMS pressure sensor of array, and size is small, and convenient for integrated, precision is high, reproducible, temperature
Degree drift is low, at low cost, these characteristics all ensure that sensor accuracy height, high reliablity, to ensure that pulse wave signal
Measurement it is accurate with it is reliable；
4, the present invention uses the body temperature transducer of array, can acquire the body of human body wrist " very little ", "Off", " ruler " simultaneously
Warm numerical value can assist pulse wave signal to carry out the judgement of human health status, provide the physiology shape of human body more accurately, in real time
State.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
