[0011] [Figure 1] FIG. 1 is a perspective view showing the appearance of a Holter electrocardiogram recording device according to an embodiment. [Figure 2] A block diagram showing the circuit configuration of a Holter electrocardiogram recording device according to an embodiment. [Figure 3] FIG. 10 is a diagram showing a copy operation of processing setting values ​​according to an embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0013] <1> Overall structure FIG. 1 is a perspective view showing the appearance of a Holter electrocardiogram recording device according to an embodiment of the present invention.

[0014] The Holter electrocardiogram recording device 100 has a device main body 110 and a battery cover 120 attached to the device main body 110 so as to be able to open and close freely. The battery cover 120 is attached to the device main body 110 via a rotating shaft 122.

[0015] The device main body 110 has a display unit 111, an event button 112a, an enter button 112b, and the like. The display unit 111 is configured, for example, with a liquid crystal display device. The user can switch the display and perform various settings by operating the event button 112a and the enter button 112b. When the event button 112a is pressed, electrocardiogram recording begins. Even if the event button 112a is not pressed, electrocardiogram recording begins automatically by a timer when a predetermined time (for example, 10 minutes) has elapsed since the power was turned on.

[0016] Battery cover 120 is provided with a locking portion 121. When locking portion 121 is in the position shown in the figure, battery cover 120 is in a locked state where it cannot be opened. On the other hand, when locking portion 121 is in a state where it has been moved downward, battery cover 120 is in an unlocked state where it can be opened. The user can insert and remove battery 151 (FIG. 2) into and from device main body 110 by setting locking portion 121 to the unlocked state and battery cover 120 to the open state.

[0017] FIG. 2 is a block diagram showing the circuit configuration of the Holter electrocardiogram recording device 100.

[0018] The Holter electrocardiogram recording device 100 has a CPU (Central Processing Unit) 131. The CPU 131 is connected to the display unit 111, the event button 112a, the enter button 112b, the ECG unit 133, the NAND flash memory unit 134, the SD card unit 135, the buzzer unit 136, the serial communication connector 137, and the acceleration detection unit 138, and controls these units or receives signals from these units to perform predetermined processing.

[0019] The CPU 131 includes an arithmetic unit 131a, a Ferroelectric Random Access Memory (FRAM) (registered trademark) 131b, and a Random Access Memory (RAM) 131c. The FRAM 131b stores programs and the like for the CPU 131 to execute predetermined processes. In the CPU 131, the arithmetic unit 131a reads the programs from the FRAM 131b and performs arithmetic processing according to the programs using the RAM 131c, thereby executing the predetermined processes.

[0020] The FRAM 131b also stores processing setting values ​​for performing electrocardiogram recording, such as the recording format (compatible mode, normal mode), recording time, recording channel (12-lead, 2ch, 3ch), sampling frequency, drift filter (ON, OFF), pacemaker detection (ON, OFF), pacemaker detection sensitivity, etc.

[0021] These are mainly used as processing setting values ​​for the ECG unit 133 and the CPU 131.

[0022] The ECG connector 132 is connected to electrodes attached to the patient.

[0023] The ECG unit 133 performs predetermined processing such as sampling and filtering on the electrocardiogram signal input from the ECG connector 132 to obtain an electrocardiogram.

[0024] Furthermore, the NAND flash memory unit 134 stores an electrocardiogram acquired by the ECG unit 133.

[0025] An SD card is inserted into the SD card section 135. The CPU 131 and the SD card section 135 work together to write the electrocardiogram acquired by the ECG section 133 to the SD card. The CPU 131 and the SD card section 135 also work together to read information written to the SD card.

[0026] Furthermore, the CPU 131 and the SD card unit 135 work together to write multiple setting value patterns stored in the FRAM 131b to an SD card as a recording medium. Furthermore, when multiple setting value patterns are written to the SD card, the CPU 131 and the SD card unit 135 work together to read these recorded setting values ​​from the SD card and store them in the FRAM 131b.

[0027] The buzzer unit 136 is controlled by the CPU 131 and can notify the patient or operator by emitting a buzzer sound when, for example, the patient presses the event button 112a while an electrocardiogram is being recorded or when an error occurs in the device.

[0028] The serial communication connector 137 is connected via a cable to an external device such as an external analyzer or a personal computer, and is capable of outputting, for example, an electrocardiogram stored in the NAND flash memory unit 134 to the external analyzer. The above-mentioned processing setting values ​​can also be input via the serial communication connector 137.

[0029] The acceleration detection unit 138 detects, as acceleration, the body movement of the patient wearing the Holter electrocardiogram recording device 100. The detection results are stored in the NAND flash memory unit 134 or an SD card.

[0030] <2> Storing and copying processing settings As described above, the Holter electrocardiogram recording device 100 of this embodiment is configured to store in the FRAM 131b the processing setting values ​​of the ECG unit 133 and the CPU 131. The ECG unit 133 and the CPU 131 function as an electrocardiogram recording unit that acquires and stores an electrocardiogram.

[0031] The processing setting values ​​can be input via the SD card unit 135. The processing setting values ​​can also be input from the serial communication connector 137. Furthermore, the processing setting values ​​can be selected and changed using the display unit 111, the event button 112a, and the enter button 112b.

[0032] The processing setting values ​​are input and stored in the Holter ECG recording device 100 before a Holter ECG recording test using the Holter ECG recording device 100 is started. The input and storage of the processing setting values ​​in the Holter ECG recording device 100 is performed, for example, by the seller of the Holter ECG recording device 100 when the Holter ECG recording device 100 is shipped or before operation begins. The input and storage of the processing setting values ​​is also performed by the user of the Holter ECG recording device 100 or a hospital staff member operating the Holter ECG recording device 100.

[0033] As described above, the processing setting values ​​include the recording format (compatible mode, normal mode), recording time, recording channel (12-lead, 2ch, 3ch), sampling frequency, drift filter (ON, OFF), pacemaker detection (ON, OFF), pacemaker detection sensitivity, etc.

[0034] The Holter ECG recording device 100 of this embodiment is capable of storing a plurality of processing set value patterns, each consisting of a plurality of processing set value patterns, as processing set values. In this embodiment, the Holter ECG recording device 100 is capable of storing five processing set value patterns (i.e., a first processing set value pattern, a second processing set value pattern, a third processing set value pattern, a fourth processing set value pattern, and a fifth processing set value pattern).

[0035] A more specific explanation will be given. The first process setting value pattern, ..., the fifth process setting value pattern each differ in at least one of the multiple process setting values ​​that make them up. For example, the first process setting value pattern differs from the second process setting value pattern in the recording time and recording channel, but the other process setting values ​​are the same. Note that the first to fifth process setting value patterns may be exactly the same.

[0036] By storing multiple processing setting value patterns in the Holter ECG recording device 100, the user can select a desired one from the multiple processing setting value patterns when performing a Holter ECG recording test.

[0037] FIG. 3 is a diagram showing the copying of processing set value patterns performed by the medical system of this embodiment.

[0038] First, in step [1], the copy source Holter electrocardiogram recording device 100a changes the processing setting values ​​and performs short-term recording (specifically, acquisition and recording of an electrocardiogram).

[0039] Next, in step [2], the Holter ECG recording device 100a writes the processing setting value pattern to the SD card. Here, when writing recorded ECG data to the SD card, the Holter ECG recording device 100a also writes the processing setting value pattern stored in the FRAM 131b. In other words, the source Holter ECG recording device 100a acquires and records a short-term ECG, and when recording it to the SD card, it also records information on multiple (all) processing setting value patterns to the SD card. This makes it possible to record processing setting value patterns to the SD card with fewer operations and functions than when opening a menu screen or the like to record processing setting value patterns to the SD card.

[0040] Next, in step [3], the SD card is read by a personal computer (PC) (not shown) serving as an information processing device.

[0041] Next, in step [4], the personal computer changes the identifier of the processing setting value read data recorded on the SD card to a readable identifier. That is, the personal computer changes the identifier of the processing setting value pattern written to the SD card by the Holter ECG recording device 100a to an identifier readable by the Holter ECG recording device 100b.

[0042] Next, in step [5], the SD card is set in the Holter ECG recording device 100b to which the data is to be copied.

[0043] Next, in step [6], the Holter ECG recording device 100b, which is the copy destination, is powered on. As a result, the Holter ECG recording device 100b stores the processing setting value pattern recorded on the SD card in its own FRAM 131b. The Holter ECG recording device 100b, which is the copy destination, reads the data based on the identifier. As a result, the Holter ECG recording device 100b, which is the copy destination, can read the processing setting value pattern without any operation (even if it does not have a screen) just by inserting the SD card.

[0044] In this way, the processing setting pattern of the Holter ECG recording device 100a is copied to the Holter ECG recording device 100b.

[0045] As described above, the Holter electrocardiogram recording device 100 of this embodiment has a display unit 111, an electrocardiogram recording unit (ECG unit 133, CPU 131) that acquires and records an electrocardiogram, a memory unit (FRAM 131b) that stores a plurality of processing setting value patterns, each consisting of a plurality of processing setting values, as processing setting values ​​for the electrocardiogram recording unit, and an output unit (SD card unit 135, CPU 131) that can write the plurality of processing setting value patterns stored in the memory unit to a recording medium (SD card).

[0046] Furthermore, the Holter ECG recording device 100 of this embodiment may have a storage unit that stores display settings for the display unit 111, and the output unit (SD card unit 135, CPU 131) may be capable of writing the display settings to a recording medium in addition to a plurality of processing setting value patterns. The display settings may specify, for example, whether or not the display direction of the display unit 111 is to be reversed vertically only during recording.

[0047] In addition, in the Holter electrocardiogram recording device 100 of this embodiment, when the output unit (SD card unit 135, CPU 131) writes out the recorded electrocardiogram data to the recording medium (SD card), it also writes out multiple processing setting value patterns stored in the memory unit (FRAM 131b).

[0048] The medical system of this embodiment includes a first Holter electrocardiogram recording device 100a having a display unit 111, an electrocardiogram recording unit (ECG unit 133, CPU 131) that acquires and records an electrocardiogram, a memory unit (FRAM 131b) that stores a plurality of processing setting value patterns, each consisting of a plurality of processing setting values, as processing setting values ​​for the electrocardiogram recording unit, and an output unit (SD card unit 135, CPU 131) that can write the plurality of processing setting value patterns stored in the memory unit to a recording medium (SD card); and a second Holter electrocardiogram recording device 100b having a reading unit (SD card unit 135, CPU 131) that can read out the plurality of processing setting value patterns recorded on the recording medium (SD card), a memory unit (FRAM 131b) that stores the read-out plurality of processing setting value patterns, an electrocardiogram recording unit (ECG unit 133, CPU 131) that acquires and records an electrocardiogram using the processing setting value patterns stored in the memory unit, and a display unit.

[0049] The setting information sharing method in the Holter ECG recording device of this embodiment includes a step (step [2]) in which the first Holter ECG recording device 100a writes out to a recording medium (SD card) a plurality of processing setting value patterns, each consisting of a plurality of processing setting values, which are stored in a memory unit (FRAM131b), and a step in which the second Holter ECG recording device 100b reads out the plurality of processing setting value patterns stored in the recording medium (SD card) and stores them in the memory unit (FRAM131b).

[0050] According to this embodiment, if the processing setting value pattern of the first Holter ECG recording device 100a is manually input, the processing setting value patterns of the remaining Holter ECG recording devices 100b can be copies of the processing setting value pattern of the first Holter ECG recording device 100a. Therefore, even when multiple Holter ECG recording devices 100 are operated, such as in a hospital, the effort required to change the processing setting values ​​and incorrect settings can be reduced.

[0051] The above-described embodiments are merely examples of specific embodiments of the present invention, and the technical scope of the present invention should not be construed as being limited by these embodiments. In other words, the present invention can be embodied in various forms without departing from the gist or main characteristics thereof.

[0052] In the above-described embodiment, the case where FRAM 131b is used as a storage unit for storing processing setting values ​​of the electrocardiogram recording unit (ECG unit 133, CPU 131) has been described, but the present invention is not limited to this, and a storage unit other than FRAM 131b may be used.

[0053] In the above embodiment, an SD card is used as a recording medium to write out the processing setting value patterns stored in the memory unit (FRAM131b), but the recording medium is not limited to this, and any recording medium capable of writing and reading data is sufficient. [Industrial Applicability]

[0054] The present invention is broadly applicable to Holter ECG recording devices that allow for configurable processing settings for Holter ECG recording tests. [Explanation of symbols]
