With respect to existing EIT patient monitor, the electrical impedance patient monitor that the present invention relates to has also increased the User Recognition plug-in unit, the User Recognition plug-in unit is connected with data acquisition module, its purposes comprises: (1) is as the user's ownership identification marking authority record medium that uses this patient monitor validated user, to guarantee user's rights of using and patient monitor safe operation; (2) as the startup self-detection of patient monitor and the dynamic calibration database in the measuring process; (3) as the batching data bag buffer memory in the network data transmission process; (4) as the off-line data exchange media.In addition, also increase network transmission and control interface circuit, be used for connecting network and high in the clouds server.
The image monitor system that the present invention relates to comes down to one based on the intelligent data acqusition system of cloud computing.Therefore, Xiang Guan high in the clouds server will provide as soft, hardware operation services such as the control of overall calculation machine, image reconstruction algorithm for brain electrical impedance monitoring operate as normal.
Above-mentioned high in the clouds server relies on 3G, WiFi, and network and electrical impedance patient monitor on lines such as Ethernet by the issue control command, are carried out the brain electrode setting to the electrical impedance patient monitor, calibration, system initialization; By the monitoring operating instruction, allow the electrical impedance patient monitor enter brain electrical impedance signals collecting flow process, patient's brain electrical impedance signal by this patient monitor is gathered uploads to the high in the clouds server with the image data frame set, by the high in the clouds server it is carried out image reconstruction process; At the patient monitor run duration, also can regularly or irregularly monitor this patient monitor working condition, safeguard and handle, until patient monitoring work come to an end out of service till.
Above-mentioned high in the clouds server also passes through 3G, WiFi, and network and control and display terminal's lines such as Ethernet are as iphone class smart mobile phone, ipad class panel computer or conventional PC, notebook computer etc.More than control and display terminal at least one even many.Wherein, according to user's rights of using, can specify wherein one (or wherein several) as control and display terminal, all the other are as display terminal.
Like this, for control and display terminal, the high in the clouds server is accepted the operational order that this control and display terminal send on the one hand, and carries out it; On the other hand the electrical impedance patient monitor is uploaded to the view data frame information of high in the clouds server, after reconstructed image, post processing of image, above image data packets is sent to control and display terminal.And simple display terminal can only accept above image data packets and show it.
The brain electrical impedance signal data that the patient produces in the monitoring process uploads to the high in the clouds server after the data acquisition of electrical impedance patient monitor.The data of thereupon carrying out image reconstruction process can comprise realtime graphic, the indication of monitoring state, generate and report and can and be stored on the server of high in the clouds by the time shaft displaying according to user (doctor) instruction.
The workflow of the image monitor system of the present invention's design is: the network transmission is connected network with the control interface circuit, makes electrical impedance patient monitor and high in the clouds server online; Open control and display terminal simultaneously, the system initialization instruction (forms such as available literal, figure, sound) that the relevant high in the clouds server that shows according to terminal sends is implemented head brain electrode group by medical personnel to the patient and is laid work, after treating that medical personnel are errorless from the affirmation of medical nursing angle, this electrical impedance patient monitor enters normal control program.
The electrical impedance patient monitor under a series of instructions of server, is finished it as parameter adjustment and inspections such as the necessary brain electrode setting of intelligent data acquisition terminal, location, calibrations beyond the clouds.If relate to because the brain electrode physical location is laid wrong, as faults such as loose contact, broken strings, after the high in the clouds server detects failure message, can get involved and correct with significant signals such as sound, light, figure, literal prompting medical personnel are artificial at control and display terminal.
After the electrical impedance patient monitor enters normal brain electrical impedance signals collecting workflow, by predefined monitoring scheme, image data and upload to the high in the clouds server frame by frame, data processing work is thereafter finished by the high in the clouds server.In the monitoring process, the high in the clouds server also can be monitored, safeguard electrical impedance patient monitor working condition by prediction scheme, except the data collection is carried out regularly, correction of timing, error correction, outside the adjustment in time of data acquisition parameter, as find that relevant brain electrode group generation physical state changes when consequently influencing data acquisition, also can in time notify on-the-spot intervention of medical personnel to safeguard with sound, light, electric signal.
In sum, the electrical impedance patient monitor that the present invention relates to comes down to a stylobate in the intelligent data acquisition equipment of cloud computing.From the high in the clouds server side, this is a mobile terminal device that inserts the cloud computing service.Well imagine, no matter be public cloud, or privately owned cloud, all might insert some these type of electrical impedance patient monitors, how to guarantee that cloud computing provides every patient monitor (being actually the patient that each is guarded) and targetedly, and be the service of uniqueness, and be unlikely the maloperation that causes " fastening one person's story upon another person "? this just need be solidificated in the device identity in this equipment, to guarantee that this electrical impedance patient monitor by closing rule enterprise's ordinary production and dispatching from the factory, secondly is the User Recognition plug-in unit of this electrical impedance patient monitor.
Further instruction, the electrical impedance patient monitor that the present invention relates to has solidified a device identity by manufacturer, and its effect is equivalent to the IMEI number of mobile phone.Because this device identity is registered in the cloud computing service end.One of its registration implication is exactly the basic software of relevant brain electrical impedance images monitoring, comprises that kernel softwares such as control program, view data aftertreatment, image reconstruction algorithm are to be provided by these electrical impedance patient monitor equipment manufacturers.Like this, hardware module, software modules such as the overall calculation machine control of conventional brain electrical impedance images patient monitor (as making according to the ZL03134598.0 patent) and image reconstruction algorithm no longer are embedded in the patient monitor that the present invention relates to goes (namely to become " one-to-many " by " one to one ", the unified high in the clouds server that is placed on provides " one-to-many " service by cloud computing itself).
In other words, only meet the electrical impedance patient monitor that the present invention relates to that registration requires (not necessarily must tame equipment manufacturers produce) and could network, the IaaS that just can obtain cloud computing provides serves.In addition, when original equipment manufacturer will be to the patient monitor software upgrading of producing, the patient monitor that also only has the corresponding device identity code obtained the online upgrading service.When if the user needs HardwareUpgring or maintenance service, this device identity also is essential.
Further specify, the electrical impedance patient monitor that the present invention relates to also has a User Recognition plug-in unit.At first be as the identification marking, the authority record that use this patient monitor validated user, to guarantee user's rights of using and patient monitor safe operation.For example, general general information resembles manufacturer, product type, date of manufacture, can be placed in the device identity; But related information is need be placed in the User Recognition plug-in unit between some users and the manufacturer: be example with the product hierarchy subsystem, the user is that full payment is bought, and still analyzes payment and buys, and perhaps lease (by using timing, metering charge) is used; Transfer equipment power of appointment or come into operation the date when; These tracking datas can guarantee or implement and close the rule rights and interests between user and the manufacturer, also provide data recording proof even measure technical application feature for both sides' standard operation.
Further instruction, this User Recognition plug-in unit can also also can be used as the batching data bag buffer memory in the network data transmission process simultaneously as the startup self-detection of patient monitor and the dynamic calibration database in the measuring process.This be because this patient monitor be rely on and the high in the clouds server between network data transmitted in both directions and judgement, execution finish dynamic calibration in startup self-detection and the measuring process.Consider the substantial time-sharing operation feature of high in the clouds server and in network transmission process data unavoidably can lose repeating transmission, might reduce the data acquisition efficiency of patient monitor like this.In addition, in the patient monitor normal work period, its duty is stable in the most of the time, parameter also is change later to be set not quite, and no longer normal tense is the small probability time, so can allow parameter to be corrected compare with the data that are reserved in the dynamic calibration database earlier by the dynamic calibration database is set in the User Recognition plug-in unit, have only overproof parameter just to upload to high in the clouds server request and further handle and carry out the correction instruction that the high in the clouds server is assigned.
The dynamic calibration data of database setting in advance when making except manufacturer, can also be replenished or be repaired according to the empirical data of scene operation accumulation by the high in the clouds server.
Further instruction need point out that also this User Recognition plug-in unit can also increase the personal information of concrete guardianship.Like this, can bring into play its off-line data exchange media effect: namely the patient only needs to shift its User Recognition plug-in unit from the intensive care unit (ICU ward) when transferring to public ward, just can work at another patient monitor.Certainly, if patient monitor in use is out of order on the way, also easily one of very fast replacing.
In the present invention, owing to introduced the cloud computing design concept, make to be reduced to the intelligent data acqusition system based on cloud computing by the brain electrical impedance images patient monitor of originally making according to the ZL03134598.0 patent.And the user of hospital only needs server registration beyond the clouds, provide in cloud computing under the situation of IaaS service and configure generic control and display device such as iPhone, iPad or notebook computer, just can realize existing conventional brain electrical impedance images patient monitor repertoire, but also possess following characteristics:
Greatly reduce the device fabrication cost---owing to only kept brain electrode and data acquisition system (DAS), saved dedicated computer hardware and a whole set of control software configuration that comprises image reconstruction algorithm.Not only the device fabrication cost reduces significantly, and machine volume greatly reduces, and has realized miniaturization, portability.
Greatly reducing use cost---former equipment is before this joined a special purpose computer and a complete set of control software, is to transfer to the high in the clouds server now.Similar like this patient monitor configuration and use are more many, and its use cost is just more low.
Low-cost has highly reliablely realized multiple terminals, removable monitoring, though allow remote diagnosis and concentrate/disperse multiple monitoring means have enforcement may---original brain electrical impedance images patient monitor has been accomplished bedside monitoring, must examine to patient bed looking on.Concentrate observation if be placed on nurses' office, must increase dedicated data transmission equipment, comprise means such as wired or wireless, so not only will acquire specialized equipment, also need the site operation transformation.Do not accomplish that in addition the nurse carries, mobile monitoring yet.Now can be low-cost highly reliable by cloud computing and mobile Internet, realize multiple terminals, removable monitoring.Concentrate as for remote diagnosis, nurses' office and the realization of all being not difficult of advanced monitoring means such as to observe, the doctor in charge understands, disperses monitoring at any time.Specifically, many mobile devices, as panel computer, the 3G smart mobile phone.
In sum, the present invention is applied to the monitoring of brain electrical impedance images by cloud computing and mobile Internet, has not only reduced the device fabrication cost, has alleviated the equipment use cost, more is conducive to penetration and promotion; Meanwhile, alleviate medical personnel greatly and guarded observation labour intensity, even can allow family numbers of patients understand the monitoring situation from now on, improved doctor-patient relationship.Also having not negligible is that this patient monitor and working condition thereof belong to low-carbon environment-friendly.
