JPH02209129A - Electroencephalograph having electronic filling function - Google Patents

Abstract

PURPOSE:To eliminate the need for a wide space for storing recording paper and to facilitate handling by providing a memory device, an AD converter which converts a brain wave signal to digital data and a CRT display which displays the brain waves converted to the digital data. CONSTITUTION:The electroencephalograph having an electronic filing function is constituted of an amplifier 1 which amplifies the brain wave signal, the AD converter 2 which execute AD conversion of the brain wave signal, a processor 3 which executes filling processing, etc., of the digital data, a keyboard 4, a magnetic disk device 5, an optical disk device 6 which stores the brain wave digital data and the CRT display 7 which displays the brain waves. The control program stored in the magnetic disk device 5 is executed by operating the keyboard 4 to convert the brain wave signal to the digital data by the AD converter 2 and to store the same in the optical disk device 6. Since the brain wave signals are electronically filed, there is no need for the wide space to store the recording paper and since the brain waves are rapidly displayed and observe on the CRT display, the handling of the data is facilitated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electroencephalograph.

[Conventional technology]

Conventionally, electroencephalographs have used recording paper to record brain waves.

[Problem to be solved by the invention]

The conventional electroencephalograph described above uses recording paper to record brain waves, so a large amount of recording paper is generated, requiring a large space to store the recording paper, and it is inconvenient to handle. There is.

[Means to solve the problem]

The electroencephalograph having an electronic file function of the present invention includes a storage device, an AD converter for converting an electroencephalogram signal into digital data, and a CR for displaying the electroencephalogram converted into digital data.
It has a T display.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. An amplifier 1 that amplifies the brain wave signal, an AD converter 2 that performs AD conversion of the brain wave signal, a processing device 3 that performs file processing of the AD converter and digital data, and a device for the operator to instruct input of the brain wave signal, etc. A keyboard 4, a magnetic disk device 5 for storing control programs, etc., an optical disk device 6 for storing digital brain wave data, and a CRT display 7 for displaying brain waves converted into digital data.

Next, to explain the operation, the user of the present invention operates the keyboard 4 to execute the control program stored in the magnetic disk device 5, thereby converting the brain wave signals into AD.
The data is converted into digital data by the converter 2 and stored in the optical disk device 6.

〔Effect of the invention〕

As explained above, the present invention provides an electroencephalograph that includes a storage device, an AD converter for converting an electroencephalogram signal into digital data, and a C for displaying the electroencephalogram converted into digital data.
By being equipped with a CRT display, brain wave signals can be stored in an electronic file, eliminating the need for a large space to store recording paper, and the brain waves can be quickly displayed on a CRT display for observation. This has the effect of making handling easier.

It is a diagram.
