Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable biosignal processing device, and particularly to a portable biosignal processing device that can be carried around for a long period of time.

[Conventional technology]

Generally, when diagnosing a disease based on biological signals such as electrocardiograms and electroencephalograms, abnormal symptoms often do not appear when tests are performed within a limited time at a hospital.

For the purpose of confirming such symptoms, portable long-term biosignal processing devices have been devised to continuously monitor and record biosignals during daily life and to extract abnormalities.

Conventional portable long-term biological signal processing devices (hereinafter simply referred to as processing devices) of this type display the date and time,
It has a built-in display means for displaying messages for simple operation instructions. The processing device is also equipped with a switch for transmitting a signal for storing the time in the processing device or for initializing the processing device when the person carrying the device becomes aware of an abnormality.

[Problem that the invention seeks to solve]

The conventional long-time portable biosignal processing device as described above is
Since the display section and the switch section are integrated into the main body of the processing device, the processing device is bulky and inconvenient to carry. Also, since it is usually carried under clothing,
The drawback is that it is difficult to check the display and operate the switches. Furthermore, when the processing device is downsized, sufficient space is not provided for the display section, so the size of the displayed characters becomes smaller or the number of displayed characters becomes smaller, making it difficult to convey sufficient information, which is difficult for the operator. It has the disadvantage of being difficult to see. When downsizing the processing equipment, it is also necessary to reduce the size of the operation switch.
For this reason, it also has the disadvantage that it becomes difficult to operate and that erroneous operations are more likely to occur. The processing device is also generally attached to the waist of the human body, and an electrode cable is connected from there under clothing to a sensor attached to the surface of the body, but it is assumed that the processing device will be removed from the body when sleeping. Therefore, the length of the electrode cable is made long to provide redundancy.

However, since the biological signals inputted from the sensor are microvoltage signals, long cables are susceptible to external noise, making it difficult to obtain high-quality signals. There is.

An object of the present invention is to provide an operation panel for a processing device that eliminates the drawbacks of the conventional portable biological signal processing device as described above, is convenient to carry, easy to operate, and is not easily affected by external noise. An object of the present invention is to provide a portable biological signal processing device that can perform signal processing of excellent quality.

[Means for solving problems]

The portable living tree signal processing device of the present invention includes a switch unit having at least one switch for transmitting predetermined information, a switch control unit that encodes and transmits a signal from the switch unit, and a designated A display section that visually displays information, a display control section that controls the operation of the display section, and a biosignal amplification section that inputs and amplifies biosignals detected by electrodes attached to the human body and sends out amplified biosignals. a processing section that inputs signals from the switch section and the biological signal amplification section, performs a processing operation, and sends out a display control signal to the display control section; It is configured by connecting the processing section with a connection cable.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In FIG. 1, 3a, 3b, and 3c are switches provided in the switch unit 3, and 10 is a switch control unit for sending a signal from the switch unit 3 to the processing unit (host) 9, and the switches 3a to 3c are The signal from the encoder is encoded and transferred to the processing section 9. 6 is a liquid crystal display control section;
In response to signals from the processing section 9, display of characters and symbols on the liquid crystal display panel 2 is controlled. 7 is an electrode attached to the human body to detect and input biological signals; 8 is an electrode 11i
This is a biosignal amplification unit that amplifies the biosignal detected in step 7 and inputted via the electrode cable (see FIG. 2) and sends it to the processing unit 9. The switch section 3 of the liquid crystal panel 2, the liquid crystal display control section 6, the switch control section 10, and the biological signal amplification section 8
is housed in one box and constitutes the operation panel 1, and the processing section 9 is housed in another box, and the operation panel 1 and the processing section 9 are connected by a connection cable. be done.

FIG. 2 is a perspective view showing the appearance of the operation panel shown in FIG. 1.

In Fig. 2, 1 is the operation panel main body (operation panel), 2
is a liquid crystal display panel provided on the operation panel 1, 3 is a switch section, 4 is a connection section for interface with the processing section,
5 is an electrode cable for biological signal transmission, and 7 is an electrode provided at the tip of the electrode cable. LCD display panel 2
displays characters and symbols in response to signals from the processing section 9 (see FIG. 1). The switch section 3 outputs a signal to the processing section 9 when switches 3a to 3c (see FIG. 1) are pressed.

A cable for transmitting and receiving signals to and from the processing section 9 is connected to the connection section 4 . The @pole cable 5 is a cable for inputting minute signals obtained from the living body by the electrodes 7 to the operation panel 1.

FIG. 3 is an external view showing the embodiment of FIG. 1 in a state where it is attached to a human body.

In FIG. 3, a processing unit 9 is attached to the waist of a human body by being attached to a belt or the like, and is used to input biological signals sent through an operation panel 1 and analyze them. Sends and receives display signals and control signals to and from 1. The operation panel 1 can be fixed to any place on clothing with a fastener, or
It can be stored in a chest pocket, etc., and taken out and operated easily when needed.

Therefore, the operation panel 1 is not limited by the location where it is mounted, so the display is easy to see and the keys can be easily operated. In addition, the distance from the electrode 7, which is the biosignal input sensor, to the biosignal amplification unit 8 in the operation panel 1 can be shortened to amplify minute biosignals (conventionally, the biosignal amplifier was included in the processing unit). ), it is possible to obtain a high-quality signal with less influence of external noise. Furthermore, since the liquid crystal display panel 1 and the switch section 3 are not limited by the device recording and analysis capacity of the processing section 9, they can be made larger than conventional ones, which reduces the chances of overlooking the display or erroneously operating a switch. Since the area of the panel 2 can be increased, the amount of information transmitted from the processing section 9 and displayed can be increased. Since the capacity is not affected, the processing unit 9 can be made smaller and can be easily carried.

〔Effect of the invention〕

As explained above, the present invention is easier to carry than conventional portable biological signal processing devices, and the display is easy to see and the switches are easy to operate, so it has the effect of reducing misidentification and erroneous operation. Furthermore, since the biological signals sent to the processing device are less affected by external noise, highly reliable processing results can be obtained.
