The healthy critical warning cloud monitoring system of naturalness night burstTechnical field
This utility model is related to biomedical devices field, and in particular to the basic vital sign parameter signals monitoring system of human body.
Background technology
In busy modern society, the health status of people can not obtain the real-time treatment and monitoring of household, night burstDisease, allows people to be caught unprepared, if treatment can not be found in time, often brings the consequence that cannot be retrieved.
Existing monitoring of respiration equipment is mostly expensive, and instrument is complicated, and needs professional to be operated, andMust also require during monitoring that monitored person wears mouth and nose formula monitor, the sensation and psychology pressure of discomfort are easily caused to monitored personPower.Existing heartbeat monitoring device mostly is electrocardiograph, and common electrocardiograph price is mostly very expensive, and operator also needsWill be through professional training.Additionally, must require that monitored person sticks multiple crosslinking electrodes in monitoring, monitored person's upper body is causedBe covered with line, easily larger psychological burden brought to monitored person, disturb diagnostic result.The bodies such as existing breathing, heart beating refer toTarget monitoring instrument is mostly independently used, and is only used for the monitoring of specialties, such as current existing electrocardiograph is notThere is the function of taking into account monitoring breathing, existing monitoring of respiration equipment does not take into account the function of monitoring heart beating yet at present, thus makesObtaining becomes difficult for real-time, the comprehensive monitoring of monitored person.
Additionally, human body is in sleep procedure, sleeping position constantly can change, and can only monitor heart beating, but be provided in being supervisedThe sensors such as the crosslinking electrode on survey person's body may be fallen off during sleeping position changes, and ultimately result in whole monitoringFailure, it is impossible to realize the purpose of monitoring.
In sum, the monitoring instrument generally existing single function of the body index such as existing breathing, heart beating, operation are multipleIt is miscellaneous, using inconvenience, signal be easily disturbed, monitor position it is inaccurate the problems such as.

Specific embodiment
This utility model is in view of the problem in terms of following four：
First, sensor can not affect the daily sleep and life of user.Therefore, this utility model adopts piezoelectric sensingDevice, piezoresistive transducer, extract people body-centered impact signal, and attitude information of sleeping is placed on the sensor in mattressPart, in order to detect the pressure signal produced by trunk.
Second, the random attitude of user can not affect measurement.As normal person is in sleep procedure, it may appear that stand up,In short-term from behaviors such as beds, this interference signal can affect the collection and judgement of heart beating breath signal.This utility model adopts frequency spectrumThe method such as analysis and auto-correlation, the signal to collecting carry out the interference that signal processing can eliminate noise, do not affect resultPrecision.
3rd, the stability of warning passage.As the radio connections such as bluetooth are easily interfered, therefore this practicality is newType adopts wired connection mode, it is ensured that the stability of data transfer.
