Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to an improvement in a portable electrocardiogram recording device.

<Prior Art> For example, some portable electrocardiogram recording devices are configured to record electrocardiograms and other processed data on an IC card attached to the device body. By developing this type of usage of IC cards, multiple IC cards can each store different operating programs for the device, and by selectively using these IC cards, the device can be programmed to perform processing tailored to the patient's symptoms, etc. A configuration that allows the device to perform an action is being considered. Particularly in recent years, automatic analysis logic for electrocardiograms has been developed, and if various analysis programs are stored in each of the above IC cards and used selectively, it is thought that a portable electrocardiogram recording device can be used extremely usefully. .

However, when operating the main unit of the device based on the program on the IC card, the transmission of signals between the IC card and the main unit of the device is performed via a connector that connects both mechanically and electrically. At present, it has not been implemented because it is difficult to obtain operational reliability. In other words, in the case of a connector connection, foreign objects may enter the connector connection part, the connector connection part may become deformed due to repeated insertion and removal of IC cards into the connector, or shock may occur when an IC card is inserted and used. Connection failures and the like are likely to occur due to disconnection, and if these occur, the main body of the device will malfunction. Particularly, in the case of a portable electrocardiogram recording device, shocks are particularly likely to be applied during use, so there is a high risk of connection failure occurring.

<Purpose of the invention> The present invention was made in view of the above-mentioned points, and is a portable electrocardiogram recording device that has high operation reliability even though it operates based on the program of the IC card that is attached and used. The purpose is to provide equipment.

<Configuration of the invention> In order to achieve the above-mentioned object, the invention uses a detector that detects an electrocardiogram signal from a living body, and the detector is connected and used, and an operation unit and the electrocardiogram signal from the detector are used. A portable electrocardiogram recording device comprising a device main body including a display section for displaying data, and a storage body that is attached to the device main body via a connector and stores an electrocardiogram recording operation program of the device main body. On the main body of the device,
a first storage unit for storing an electrocardiogram recording operation program stored in the storage body; and a first storage unit for storing an electrocardiogram recording operation program stored in the storage body;
a second storage section storing a transfer operation program to be transferred to the storage section and a check operation program for the electrocardiogram recording operation program transferred to the first storage section; An operation control section is provided for controlling a transfer operation of the electrocardiogram recording operation program and a check operation of the transferred electrocardiogram recording operation program based on the transfer operation program and the check operation program. The structure is as follows.

According to the above configuration, when an electrocardiogram recording operation is performed, the electrocardiogram recording operation program stored in the attached storage body is transferred and stored in the first storage section of the device main body, and the transfer to the first storage section is normally performed. After checking whether the electrocardiogram has been performed correctly, the electrocardiogram recording operation is performed based on the electrocardiogram recording operation program, so that the electrocardiogram recording operation is always performed normally.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block circuit diagram showing the configuration of a portable electrocardiogram recording apparatus according to the same embodiment.

In the figure, numeral 1 is a detection electrode section as a detector for detecting electrocardiogram signals from a living body, 2 is a main body of the device to which the detection electrode section 1 is connected, and 3 is a storage body attached to the main body 2 of the device. It is an IC card.

The device main body 2 includes a key section 4 as an operation section, a liquid crystal display section 5, a drive circuit 6 for the liquid crystal display section 5, an amplifier 7 for amplifying the detected electrocardiogram signal from the detection electrode section 1, and a signal from the amplifier 7. An A/D converter 8 that A/D converts the amplified signal, a D/A converter 9 that D/A converts the output signal, and an amplifier that amplifies and outputs the converted signal from the D/A converter 9 to the outside. 10, a ROM (second storage section) 11 for storing a transfer operation program and a check operation program, and a RAM 12 (first storage section) for storing an electrocardiogram recording operation program transferred from the IC card 3. )
and a central processing unit 13 as an operation control unit configured by a microcomputer.

The IC card 3 has a built-in ROM 14 for storing an electrocardiogram recording operation program and a RAM 15 for storing electrocardiogram data, etc.
The IC card 3 is connected to the device body 2 via the connector 16.
It is now being installed on

The portable electrocardiogram recording device has the above-described configuration, and processes the detected electrocardiogram signal given from the detection electrode section 1, the output processing operation to an external device through the amplifier 10, the display operation on the liquid crystal display section 5,
ROM11 and ROM11 support operations for IC card 3, etc.
This is performed in a predetermined procedure under the operation control of the central processing unit 13 based on the program stored in the RAM 12.

Next, the electrocardiogram recording operation will be explained with reference to the flowchart of FIG.

First, before using the device, an IC card 3 having an operating program corresponding to the patient's symptoms is selected, and the IC card 3 is attached to the device main body 2 via the connector 16.

When an operation start signal is given by the key section 4, the transfer operation program stored in the ROM 11 of the device body 2 is used to transfer the IC card 3.
The electrocardiogram recording operation program stored in the ROM 14 is transferred to the RAM 12 of the apparatus main body 2 and stored therein (step S1). Next, based on the check operation program stored in the ROM 11, the RAM
The electrocardiogram recording operation program transferred and stored in step 12 is read out, and it is determined whether the transfer of the electrocardiogram recording operation program has been correctly completed (step S2). If completed correctly, the electrocardiogram recording operation is performed based on the electrocardiogram recording operation program transferred and stored in the RAM 12, and data based on the detected electrocardiogram signal obtained from the detection electrode section 1 is stored in the RAM 15 of the IC card 3. (Step S3).

The determination operation in step S2 above is performed in step S4.
If the transfer is not completed even though the judgment operation in step S2 is repeated a specified number of times, a transfer abnormality display signal is output and the liquid crystal display section 5 indicates that the transfer is abnormal. Display the message (step S5) and move on to the next operation. The operator of the device should check the connector 16 based on the displayed transfer error message.
The connection failure of the IC card 3 to the main body 2 of the device can be recognized, and the IC card 3 can be reinstalled.
Perform the recording operation again.

The electrocardiogram recording operation at step S3 is
The recording operation continues for a predetermined period of time according to the recording operation continuation determination operation in S6, and then it is confirmed that the content of the RAM 15 is read and the checksum matches (step S7), and if they match (step S8), a procedure completion signal is output. , the procedure completion message will be displayed on the LCD display section 5.
(step S9) and move on to the next operation. If they do not match, a procedure error signal is output to display a procedure error message on the liquid crystal display section 5 (step S10), and the process moves to the next operation. If a procedure failure message is displayed on the liquid crystal display section 5, the operator reinstalls the IC card 3 into the connector 16 and performs the recording operation again.

As mentioned above, in step S1, the IC card 3
The electrocardiogram recording operation program is transferred from the ROM 14 to the RAM 12 of the main body 2 of the device, and the transfer status is checked in step S2. Only when there is no abnormality in the connector 16 and the transfer is being performed normally, the program is transferred in step S3. Since the electrocardiogram recording operation is performed, malfunctions are reliably prevented.
