Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recorder having a plurality of channels in which an index code for distinguishing the recorded information recorded on recording paper is recorded together with the recorded information.

Conventionally, as shown in FIG. 1, the index code written in a recorder having multiple channels, such as an electrocardiograph or a phonocardiograph, is such that the patient code number 10 is 1.2, 3.4, etc. If the electrocardiograph has 4 channels, a code number 10 of 1, 2, 3.4 in binary coded decimal system is recorded for each channel indicating the waveform of the electrocardiogram 11 obtained at each part of the body. is normal.

In code number 10 in the figure, a wide pulse is a logic 1, and a narrow pulse is a logic 0.

In this way, electrocardiographs and the like simultaneously obtain information from four channels of different leads from the same body and record it simultaneously on a single sheet of recording paper, but with conventional recorders like this, Since the same code number is recorded for each channel, the same code number is recorded for 4 channels on the same recording paper, which is a waste of recording paper and has the disadvantage that it takes more time to record. there were.

In order to improve these drawbacks, the present invention provides a plurality of external display devices each displaying one digit of the index code 1 in a multi-channel recorder that records record information following the index code; It is equipped with digital pattern generators that each generate digital patterns corresponding to an external display device, and a recording section that is provided corresponding to these digital pattern generators and records information from the measuring section together with each of the digital patterns. An object of the present invention is to provide a recorder having a plurality of channels, which is characterized in that an index code is divided into a plurality of channels and recorded.

The details will be explained below.

FIG. 2 is a block diagram showing one embodiment of the present invention.
is an external display device consisting of a numeric keypad or the like that displays the patient code, and this external display device 20 has multiple channels, in the case of this embodiment, 4 channel unit devices 20a, 20.
b, 20C, and 20d are provided, and each unit device displays one number.

21 is a digital pattern generator, and each unit device 20 a , 20 b , 20 C, of the external display device 20
Unit devices 21 a , 21 b , 2 corresponding to 20 d
1C, 21d are provided, and generate corresponding digital patterns based on signals from each unit device of the external display device 20.

Reference numeral 22 denotes a recording unit consisting of, for example, a heat pen display recorder using a galvanometer, and each unit device 21a, 21b, 21C, 21 of the digital pattern display device 21
Unit devices 22a and 22b correspond to d.

22C and 22d are provided, and corresponding patterns are recorded on the same recording paper by signals from each unit device of the digital pattern display device 21.

Reference numeral 23 denotes a measuring unit such as an electrocardiograph that extracts information such as electrocardiographic signals from the body, and four electrocardiographic signals of different leads in the same body obtained from the measuring unit 23, for example, the electrocardiograph, are recorded. Each unit device 22 a , 22 b , 22 of the section 22
C, 22d, and is recorded following each of the above-mentioned patterns.

That is, for each unit device, a is 1000, b is 100.
C 10. Set the pattern with d as the 1st digit, and
- The fourth channel is divided into four channels and written on the same recording paper.

Figure 3 is a diagram showing the pattern recorded in this way (patient code) and the recording status of the electrocardiogram. The pattern (patient code) 31 is an electrocardiogram obtained from four different leads.

As described above, according to the present invention, the index code such as patient code is divided into multiple channels and recorded, so the portion of the index code that occupies the recording paper can be reduced compared to the conventional method. Therefore, there is no waste of recording paper, and the recording time can be shortened.
