Abstract

PURPOSE:To reduce the burdent of a checked person during measurement by providing a measurement analyzing device, which digitalizes electrocardiogram information to be measured through an electrode cable and stores the information in a built-in memory, and a monitor device to read the electrocardiogram information in the memory and to display the contents of the information. CONSTITUTION:Cardiac electro motive force, which appears from plural electrodes to the surface of a human body, is conducted to an electrocardiogram input part 3 by an electrode cable 1a which is fit to a patient 15, to have the electrode. A signal to be outputted from the electrocardiogram input part 3 in each conduction to correspond to each electrode is amplified by a main amplifying part 4 and digitalized by an A/D converting part 5. Then, after the signal is passed through a digital filter in a digital signal processing part 6, the analysis processing of the electrocardiogram is executed to the signal and the signal is stored in a memory 7. The control of those operation is executed by a main control part 8. After the measurement is finished, a monitor device 2 is connected through a connecting cable 2a to a measurement analyzing device 1. Records to be stored in the memory 7 are displayed through a monitor control part 9 and a monitor interface 11 to a display part 10 by operation from an operating part 12.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a portable electrocardiograph.

[Conventional technology]

Conventional portable electrocardiographs have a display device built into the main body of the portable electrocardiograph to display the electrocardiogram waveform being analyzed, the heart rate and time during measurement, and to perform initial settings before measurement. It was designed so that the display device connected to the main body was carried along with the main body.

[Problem to be solved by the invention]

The conventional portable electrocardiograph mentioned above displays the electrocardiogram waveform and requires a display function to display the heart rate and time during measurement or to perform initial settings before measurement. The device must be built into the main body of the portable electrocardiograph, or a display device must be carried in addition to the main body of the portable electrocardiograph; in the former case, in order to secure space for the display device such as an LCD,
This method has the drawbacks of increasing the size and weight of the analysis device, and increasing the number of devices that the subject must carry.

[Means to solve the problem]

The portable electrocardiograph of the present invention includes a measurement analysis device that is independently carried and constantly measures electrocardiogram information through an electrode cable, and stores the digitalized electrocardiogram information in a built-in memory; and a monitor device that reads electrocardiogram information and displays the contents.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In Figure 1, 1 is a measurement analysis device, 2 is a detachable monitor device, 3 is an electrocardiogram input section, 4 is a main amplification section, and 5 is an A
6 is a digital signal processing unit that analyzes A/D converted electrocardiogram data; 7 is a memory; 8 is a main control unit; 9 is a monitor control unit that controls a detachable monitor;
0 is a display unit for displaying waveforms and time, 11 is a monitor interface circuit between the analysis device and the monitor device, 1
Reference numeral 2 represents an operation unit for performing initial settings before measurement.

FIG. 2 is an external view of this device. 1 measurement analysis device and 2
The monitor device is connected by a cable 2a, and both can be easily attached and detached. When performing initial settings before measurement or monitoring measured waveforms, use measurement analysis device 1 and monitor device 2.
In the actual measurement, the measurement analysis device 1 and the electrode cable 1a are carried and measured.

Next, the operation of this embodiment will be explained.

An electrode cable with electrodes attached to the patient 15 allows the electromotive force appearing on the surface of the human body from multiple electrodes to be transmitted to the patient 15.
A signal output from the electrocardiogram input section 3 for each lead corresponding to each electrode, which is led to the electrocardiogram input section 3, is amplified by the main amplification section 4, digitized by the A/D conversion section 5, and then sent to the digital signal processing section. After being passed through a digital filter in step 6, the electrocardiogram is analyzed and stored in memory 7. Further, these operations are controlled by the main control section 8. In this way, when a certain predetermined time has elapsed and there is no more room in the memory 7 or the built-in current from the battery drops below a certain voltage, the measurement is stopped.

On the other hand, after the measurement is completed, the monitor device 2 is connected to the measurement analysis device 1 through the connection cable 2a.

Then, the records stored in the memory 7 are displayed on the display section 1o through the monitor control section 9 and the monitor interface 11 by an operation from the operation section 12. This display section 1
0 can be a CRT or a Venn recorder, or the monitor device 2 can be equipped with a modem or the like and can be sent to a remote location via a telephone line.

〔Effect of the invention〕

As explained above, the present invention enables a subject to monitor for long periods of time by removing a detachable monitor device from a portable electrocardiograph that has real-time electrocardiogram waveform display, initial settings before measurement, and time display functions. This has the effect of reducing the size and weight of the measurement and analysis device that must be carried, and reducing the burden on the subject during measurement.
