Description
Technical field
This utility model belongs to a kind of medical monitor.
Background technology
In the Medical Multi-Qarameter Monitor Instrument device, usually need a plurality of different physiological signals are guarded, as electrocardio, blood pressure, blood oxygen saturation, brain electricity etc.The mechanism difference that these physiological signals produce, characteristics are also different, so can not adopt unified signal acquisition circuit.But as medical monitor, these signals will finally be simultaneously displayed on the screen of monitor or send in the middle of the computer.In the design of present monitor, usually adopt modularized design to realize collection to different physiological signals, promptly adopt the specific modules circuit at specific physiological signal.Simultaneously, because the frequency band difference of various physiological signals concentrates on 0.01-100Hz as electrocardiosignal, blood oxygen waveform concentrates on 0.5-40Hz etc.According to sampling thheorem, the sample frequency of their corresponding Acquisition Circuit also is not quite similar, and is generally 250Hz as the sample frequency of electrocardiosignal, and the sample frequency of blood oxygen waveform is generally 100Hz etc.When having a plurality of signal acquisition module in the multi-parameter monitor, the employing frequency difference of these signal acquisition module, so the monitor host circuit needs particular design, could guarantee from each signal acquisition module, to obtain the data that collect with certain bus frequency.So, in the presence of all after multimode is connected on the monitor main frame simultaneously, problems such as mutual interference mutually in the time of just must considering Interface design, module work independence, the compatible property of module, the multimode transfer of data between module and the monitor main frame and bus frequency compatibility, this has increased the extra work burden for undoubtedly the design work and the use of monitor.
Summary of the invention
This utility model provides a kind of medical monitor that adopts the general module interface, the technical barrier of signal asynchronous transmission makes different physiological signals to transmit on identical monitor module interface and monitor system bus when gathering simultaneously to solve different physiological signals.
The technical scheme that this utility model is taked is: electrode or pick off are connected with functional module, and functional module is connected with data buffer circuit by the module internal bus, and data buffer circuit is connected with the central processing unit of host circuit by the general module interface.
Functional module comprises amplifier, and this amplifier is connected with wave filter, this wave filter is connected with analog-digital converter, and this analog-digital converter is connected with microprocessor.
This utility model advantage is to adopt the general module interface, has realized communication, monitor physiological signal acquisition module and the compatibility of monitor host circuit on bus frequency of difference in functionality module and monitor main frame in the medical monitor device.Guarantee monitor physiological signal acquisition module with own constant frequency work, and can allow the monitor host circuit from different modules, read the data that collect with fixed bus frequency.Reduced the workload of Interface design in the monitor design process, made that simultaneously the function of monitor is more flexible, the user can purchase the monitor functional module as required, voluntarily the function of monitor is adjusted.Adopt unified hardware configuration and software logic to realize that different monitor functional modules can communication under unified interface standard.And, adopted hardware based data Caching Mechanism, make the transfer of data of module be independent of each other, and guaranteed the stable of transmission data.And under the standard of this general-purpose interface, can adjust the size and the quantity of data buffer zone according to the characteristics of specific physiological signal, make the application of interface more flexible, the suitability is stronger.
Description of drawings
Fig. 1 is this utility model schematic block circuit diagram;
Fig. 2 is the circuit theory diagrams of this utility model general module interface.
The specific embodiment
Electrode or pick off 6 are connected with functional module 5, and functional module 5 is connected with data buffer circuit 3 by module internal bus 4, and data buffer circuit 3 is connected with the central processing unit 201 of host circuit 2 by general module interface 1.
Functional module 5 comprises amplifier 501, and this amplifier is connected with wave filter 502, this wave filter is connected with analog-digital converter 503, and this analog-digital converter is connected with microprocessor 504.
Operation principle: at first whether the software detection of monitor host circuit 2 inside is connected to functional module 5 on the interface, inserts as functional module 5, and then specific unit, access modules inner space obtains its module code, and then has determined type of module; Then, monitor transmits control signal, passes through main frame general module interface 1 physiological signal that from the data buffer circuit 3 of module interface read functions module gather by control bus to functional module 5 according to different functional module type, and electrode or pick off 6 are sent the physiological signal of gathering into functional module and handled.
Can there be several function module 5 simultaneously in the monitor system.
By pinout shown in Figure 2, comprise data/address bus, address bus, control bus, duplex feeding circuit in this general module interface 1 and insert ready pin.Wherein data/address bus is used for the physiological signal data that the monitor module collects is transmitted, and is connecting data buffer circuit; Address bus provides independently 256 byte inside modules spaces for each inside modules; Control bus provides the input and output of various control signals and status signal, and these buses all connect in host bus by triple gate; The duplex feeding circuit is used for module is powered in the interface, and design has the hot plug holding circuit on the 5V supply access, is used to provide the hot plug function; Insert ready pin and be used for detecting and whether have module to insert this interface, be input in the host computer system by logic circuit.
