Description

Brain electricity holographic process instrument

The utility model relates to a kind of Medical Instruments, particularly relates to a kind of brain electricity holographic process instrument.

It is the Medical Instruments that detects brain diseases that the brain electricity that uses does not at present have a recording instrument, and generally it is made up of amplifier, microcomputer, printer and dongle.The EEG signals amplifier is used for gathering, amplifying EEG signals, be converted to digital signal through A/D, the storage of input microcomputer send display to be shown as visible brain wave for the brain wave data file, and eeg data is carried out the frequency domain amount handle, provide quantitative result and topomap result.Brain wave and result are sent printer, form printed report, and dongle is used to protect special-purpose brain electric treatment program.Because the brain electric information amount is too big, full detail can not be printed, can only get wherein that sub-fraction shows and printout, can occur like this " fan out from point to area " shortcoming that data is incomplete.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of the brain wave full detail of being gathered is handled, and can be shown as the brain electricity holographic process instrument of compression brain electricity hologram.

The utility model brain electricity holographic process instrument is achieved in that its circuit comprises amplifier A1, and microcomputer, and the printer that is connected with microcomputer are inserted with the smart card that is connected with amplifier A1 output terminal on computer motherboard IC4 slot.The bus of smart card is consistent with mainboard IC4 bus.Wherein, smart card is by simulating switch I C0, single-chip microcomputer IC1, dual port RAM IC2 and programmable gate array IC3 constitute, its annexation is, output terminal OUT0～OUT15 of amplifier A1 meets IC0 input end IN0～IN15, IC0 output terminal COM meets IC1 input end PD0, IC0 input end A, B, C and D meet IC1 OPADD end PD1～PD4, IC1 data double-way end PA0～PA7 meets IC2 data terminal DA0～DA7, IC1 address end PB0～PB7 meets address end AA0～AA7 of IC2, IC1 address end PC0～PC3 meets IC2 address end AA8～AA11, IC1 control end PC4～PC6 meets IC2 respectively and writes end WRA, read to hold RDA and sheet choosing end CEA, WRA is held in writing of IC2, read to hold RDA and sheet choosing end CEA to meet three output terminal O0 of IC3 respectively, O1 and O2, IC3 input end I7 meets IC1 output chip choosing end PC7, IC2 data terminal DB0～DB7 meets mainboard IC4 data line D0～D7, IC2 address end AB0～AB11 meets IC4 address end A0～A11, IC4 address end A16～A19 meets IC3 input end I0～I4, IC4 writes control end MEWR and meets IC3 input end I5, IC4 reads control end MERD and meets IC3 input end I6, and broken ends of fractured bone IPQ10 meets IC3 output terminal O3 among the IC4.

The principle of work of the utility model brain electricity holographic process instrument is, smart card wherein is used to protect dedicated processes software, and single-chip microcomputer IC1 wherein is the integration member of devices such as the conversion of A/D12 position, ROM, RAM.Amplifier A1 exports 16 tunnel simulating signals, IC1 is converted to digital signal through single-chip microcomputer, ROM can store holographic management job sequence, like this, the program that the beginning main frame reads in is inexecutable data, and behind the input smart card, the preservation job sequence of ROM is processed processing in single-chip microcomputer IC1, become executable program, fail back main frame again and carry out holographic process, obtain a compressed brain electricity hologram.

The advantage of the utility model brain electricity holographic process instrument is and can handles detecting whole brain waves of collecting, and be compressed into hologram with 1: 10,1: 100 ratio, can preserve the feature of original long-time brain wave, it also is a kind of new method for expressing of brain wave, can provide more comprehensive data for clinical, increase its objectivity and confidence level, be exclusively used in the inspection of brain diseases.
