Description
Technical field
The present invention relates to a kind of intelligent controlling devices and control method of target blood oxygen saturation, make when belonging to oxygen inhalation therapy
Medical instrument.
Background technology
Oxygen inhalation therapy（Referred to as " oxygen therapy "）It is one of the most commonly used rescue of hospital or treatment means, the purpose is to by giving
Patient's oxygen uptake improves the blood oxygen saturation of patient and is stably held in reasonable interval, and oxygen closes not caused by correcting a variety of causes
Normal condition maintains body vital movement.Country's oxygen therapy is substantially at a kind of state without ready patterns to follow, or even most medical cares at present
Personnel are also considered as that oxygen therapy is useful and harmless, and more therapeutic effects that oxygen is given are better, in clinical practice in most cases oxygen therapy without tight
The doctor's advice of lattice.Entire process of oxygen therapy lacks strict monitoring and necessary flow regulating measures, is not provided having doctor's advice
Specific oxygen therapy target blood oxygen levels, this clinical status will necessarily influence the therapeutic effect of patient, can not also ensure the peace of oxygen therapy
Full property even causes serious adverse consequences（Such as various types oxygen poisoning or increase the death rate）.
Target blood oxygen saturation refers to the normal blood oxygen levels that the patient should reach in process of oxygen therapy, that is, to patient's oxygen
Treat the therapeutic purpose that should be realized.This concept of target blood oxygen saturation is by association of division of chest disease of Britain (BTS）Acute disease oxygen therapy guide（2008
Version）In take the lead in proposing, and suggest for the first time using blood oxygen saturation as " the 5th life except heartbeat, breathing, blood pressure and pulse
Indication ", which proposes to need to mark the target blood oxygen saturation clearly treated when oxygen therapy, and suggests to monitor and keeping it
Target blood oxygen saturation reaches target blood oxygen stationary value.Although existing multi-parameter monitor, pulse blood oxygen instrument etc. can be supervised effectively
Survey blood oxygen saturation, but due to oxygen output control be with its mutually independent system, can not in oxygen therapy clinical practice
Effectively realize that the control of target blood oxygen saturation is kept with stable.
Invention content
The present invention proposes a kind of intelligent controlling device and control method of target blood oxygen saturation, is mainly controlled by system
Module, oxygen saturation monitor module, flow control valve, flow measurement module, human-computer interaction interface, communication module and control algolithm group
At, wherein：
The system control module is based on using programmable logic controller (PLC)（PLC）/ or single chip foundation on develop
Integrated circuit, the unicom such as system control module and oxygen saturation monitor module, flow control valve, flow measurement module, communication module,
It cooperates.
The oxygen saturation monitor module is mainly made of blood oxygen probe, blood oxygen computing module and conducting wire, for dynamic
Monitor the blood oxygen saturation, pulse frequency, perfusion index of patient（PI）.Certainly, probe for detecting temperature can also be embedded in oxygen saturation monitor module
Deng the multi-parameters dynamic monitoring such as realization patient pulse, blood oxygen saturation, body temperature.
The flow control valve is used for the adjusting of oxygen flow size.According to the control mode difference of flow control valve point
For two kinds of manual adjustment and automatic adjustment, electronic flow control valve is preferably used in of the invention, according to system control module
The automatic adjustment of uninterrupted is realized in the instruction provided, executes valve opening, flow adjustment, valve that system control module provides
The work orders such as closing.
The flow measurement module is used for the monitoring and metering of output flow in oxygen therapy.
Operation and control of the human-computer interaction interface for the present invention, generally uses liquid crystal display and functional key structure
At.Human-computer interaction interface should at least be equipped with oxygen uptake duration set key, flow set key, switch key, can also be by target blood oxygen
Stationary value set key or target blood oxygen control range set key are integrated in human-computer interaction interface.
Monitoring-information, information warning etc. of the communication module for monitoring data, analysis synthesis are sent remotely to cure
Learn monitoring terminal.The technical approach such as wire transmission, bluetooth, WiFi or RF generally can be used in communication module.
The control algolithm（The control algorithm）It is core of the invention control program, control algolithm
Establishing element includes mainly target blood oxygen stationary value, target blood oxygen control range, doctor's advice flow value, intervention control time, oxygen
Flow adjustment range, oxygen uptake duration, wherein：
The target blood oxygen stationary value refers to it is expected to reach and stablize the blood oxygen levels of holding in oxygen therapy, that is, this oxygen therapy is pre-
The oximetry value that phase reaches.
The target blood oxygen control range refer in oxygen therapy centered on target blood oxygen stationary value, allow occur blood oxygen
Intensity value deviates section, i.e., the minimum value and maximum range of the blood oxygen saturation of control and holding should be realized in oxygen therapy.
The flow value that medical staff sets when the doctor's advice flow value is oxygen therapy, when oxygen therapy in human-computer interaction interface/or
It is set in upper computer software, generally with minute（L/min) it is unit.
The intervention control time refers to system control module after patient's dynamic blood oxygen levels deviate target blood oxygen stationary value
The time of intervention adjustment oxygen output flow.Intervene the stabilization retention time for the target blood oxygen levels that control time is needed according to clinic
It is set for foundation, generally with minute（min）For unit, intervention control time is set between 0~60min；Preferable scheme is that：
The intervention control time for reducing flow-rate adjustment is 1~5min, increases intervention control time Wei≤0.5min of flow-rate adjustment.Work as trouble
When person's dynamic blood oxygen saturation is stably held in target blood oxygen stationary value or more and reaches intervention control time, such as dynamic blood oxygen
Saturation degree is stablized more than target blood oxygen stationary value keeps 3min, and system control module instructs flow control valve to reduce oxygen output
Flow；When patient's blood oxygen saturation is stably held in target blood oxygen stationary value or less and reaches intervention control time, for example, it is dynamic
State blood oxygen saturation is less than target blood oxygen stationary value and stablizes holding 0.5min, and system control module instructs flow control valve to increase
Oxygen output flow.In order to improve the safety of oxygen therapy, when patient's blood oxygen saturation meets or exceeds target blood oxygen control range
Critical point（That is maximum value or minimum value）When, then setting, system control module current order should be minimized by intervening control time
Flow control valve carries out the adjustment of oxygen output flow, that is, when patient's blood oxygen saturation meets or exceeds maximum value, is
System control module turns down oxygen output flow immediately, and when patient's blood oxygen saturation meets or exceeds minimum value, system controls mould
Oxygen output flow is turned up in block immediately.On the basis of this blood oxygen stationary value by target, adjustment oxygen output flow is dynamically intervened,
Purpose is that patient's dynamic blood oxygen saturation is made to control always in target blood oxygen control range, ensure that the validity and peace of oxygen therapy
Quan Xing.
