Description

A kind of exceptional state alarm method and system of lung ventilator cloud platform
Technical field
The present invention relates to medical instruments field, more particularly to a kind of exceptional state alarm method of lung ventilator cloud platform and it is System.
Background technology
Lung ventilator is conventional self-supporting medical equipment.It is to establish pressure differential with mechanical device, so as to produce alveolar ventilation Principle of dynamics be made, can be used for replacing, control or changing the autonomous respiration campaign of human body, while can also monitor to breathe The events such as pause, low pass gas, snoring, flow limitation, and different respiration cases can be made a response automatically and pressure adjustment.
With the gradual popularization of lung ventilator, people start to give the safety issue of home ventilator more concerns, Lung ventilator is sought under abnormality, reliable alert notice can be provided.The exceptional state alarm of lung ventilator mainly uses sound at present Light alarm mode, its method design the mainly reliability from system, the comprehensive of warning message(A kind of failure of lung ventilator Alarm method, the B of CN 103893867).In addition, also there is invention to propose a kind of remote control alarming unit, the purpose is to solve to breathe Machine, which is stopped, can not notify the technical problem of patient and how by wireless communication technology straighforward operation lung ventilator(One kind breathing The remote control alarming unit and lung ventilator of machine, the U of CN 204951875).
In the work for realizing the present invention, inventor has found that prior art ignores home ventilator user's usage scenario Particularity.The late into the night is the groundwork period of home ventilator, and bedroom is the command module of equipment, and this is all to frightened Disturb time and the region of quite sensitive.Because house rehabilitation corresponding to home ventilator and the management of chronic disease are all one Long-term process, therefore, it is necessary to the influence to caused by other kinsfolks during considering its use.
Meanwhile as the development of internet medical technology, the various medicine equipments with network savvy are increasingly general.Family expenses join Powerful data storage, the disposal ability of net medical terminal combination cloud platform offer, it is house rehabilitation and the chronic disease of patient Management provide remote monitoring, diagnosis facility.At present, more and more home ventilators by cloud platform management occur (Lung ventilator integration method, cloud platform and lung ventilator of the CN105031786A based on cloud platform;A kind of clouds of CN105232049A are put down Platform), this versatility to alarm terminal it is also proposed higher requirement.
At present, specifically there are following three points in ventilator alarm technology:
1. warning reminding is without Objective.At present, in a manner of the fault alarm by acousto-optic for means that lung ventilator uses, because acousto-optic passes The characteristic broadcast, no particular alarm recipient, the ortho of relatives around user can be produced when low-risk failure occurs Unnecessary agitation;
2. the tactful indifference opposite sex of alarm.At present, lung ventilator is not to different types of user and abnormal conditions customization differentiation report It is pithy to omit;
3. the particularity of wireless alarmer.At present, lung ventilator remote control alarming unit is all the hardware for needing additional customized, is not had There are versatility and generality.
The content of the invention
To solve above three technical problem, the invention provides a kind of exceptional state alarm method of lung ventilator cloud platform And system, on the premise of ensure respiration machine abnormal alarm security, accuracy and promptness, realize the side of alert receipt object Tropism, the otherness for strategy of alarming, the person that alarm can be accurately conducted to Use of respirator, so as to avoid some low wind The relatives of surrounding are arrived in dangerous fault alarm agitation, meanwhile, the warning device user terminal of this method and system only needs common intelligence Bracelet and smart mobile phone, due to using general hardware device and unified remote alarm interface, going for the various types of different vendor Number have high in the clouds management lung ventilator, warning system application upgrade proposed by the invention is based on the soft of smart mobile phone APP Part upgrades.
It according to method provided by the invention, can be achieved according to user's state of an illness and lung ventilator fault type, set corresponding disease Feelings index and fault level index, to different faults risk class, using different alarm means, and lifting alarm is strong step by step Degree, and expand alarm range.Abnormal for lung ventilator, cloud platform judges fault type first(As mask comes off and abnormal power-down Deng), the alarm command that cloud platform is sent is pushed to smart mobile phone by APP, and smart mobile phone is transmitted to intelligence by near-field communication again Energy bracelet, Intelligent bracelet triggering vibrations motor precisely send alarm to Use of respirator person, and alarm continues the time of a setting Window, until user has action actively to release alarm.If user is in the time window of setting without actively confirming and solve Except the action of alarm, then lung ventilator failure risk is upgraded, while fault alarm scope is expanded, keeping Intelligent bracelet vibrations While notice, APP opens the tinkle of bells of smart mobile phone, until the user or its periphery family members that wake up with a start, actively release until having Actuation of an alarm.
Key technology point is used by the present invention solves its technical problem:
First, the node using smart mobile phone as connection lung ventilator cloud platform and Intelligent bracelet;Secondly, Intelligent bracelet and intelligence are utilized Can mobile phone realize the abnormal orientation alarm of lung ventilator and classifying alarm;Finally, present invention firstly provides referred to according to user's state of an illness Number and lung ventilator fault level index, and carry out the size of control time window accordingly.
The solution have the advantages that:On the one hand, compared with the prior art(A kind of remote control alarming unit of lung ventilator and breathing Machine, the U of CN 204951875)For have more the versatility of hardware, can play that smart mobile phone communication interface is abundant, at computing The characteristics of reason ability is strong, what is more important lung ventilator are bound by special APP and lung ventilator cloud platform, follow-up system liter Level, the extension of function are more convenient;On the other hand, the abnormal orientation report of lung ventilator is realized using Intelligent bracelet and smart mobile phone Alert and classifying alarm.
