Description

Description: TECHNICAL FIELD The present invention relates to a portable bio-signal processing apparatus, and more particularly to a portable bio-signal processing apparatus for carrying each other for a long time.

[Conventional technology]

In general, when diagnosing a disease from a biological signal such as an electrocardiogram or an electroencephalogram, there are many cases where abnormal symptoms do not appear only by a usual examination within a limited time within a hospital.
For the purpose of confirming such a symptom, a portable long-time biological signal processing device has been devised in order to continuously monitor and record a biological signal in daily life and extract an abnormal portion. Conventionally, a portable long-time biological signal processing device of this type (hereinafter simply referred to as a processing device) has a built-in display unit for displaying a date and time and a message for a simple operation instruction. . Further, the processing device is equipped with a switch for storing the time in the processing device when the carrier becomes aware of the abnormality, or for transmitting a signal for initializing the processing device.

[Problems to be solved by the invention]

The conventional long-running type biomedical signal processing device as described above,
Since the display unit and the switch unit are integrally provided in the main body of the processing apparatus, the processing apparatus is bulky and inconvenient to carry. Also, since it is usually worn under clothes, it is carried,
It has a drawback that it is difficult to confirm the display and operate the switch. In addition, when the processor is downsized, it is necessary to avoid sufficient space in the display unit, so the size of the displayed characters becomes small, or the number of displayed characters becomes small, and it is not possible to transmit sufficient information, which is also for the operator It has the drawback of being difficult to see. When downsizing the processing device, it is necessary to reduce the size of the operation switch.
For this reason, there are drawbacks that the operation becomes difficult and the number of erroneous operations increases. The treatment device is also typically worn on the lower back of the human body, and electrode cables are connected underneath clothing to the sensor attached to the body surface, but it is assumed that the treatment device will be removed from the body at bedtime. Thus, the length of the electrode cable is made long with redundancy.
However, since the biomedical signal input from the sensor is a minute voltage signal, if the cable is long, it is easily affected by external noise, and thus it is difficult to obtain a high quality signal. .

An object of the present invention is that the operation panel for a processing device eliminates the above-mentioned drawbacks of the conventional portable biological signal processing device, is convenient and easy to carry, and is not easily affected by external noise. It is an object of the present invention to provide a portable bio-signal processing device capable of performing signal processing of excellent quality.

[Means for solving problems]

The portable biological signal processing device of the present invention includes a switch unit having at least one switch for transmitting predetermined information, a switch control unit for encoding and transmitting a signal from the switch unit, and designated information. And a display control unit that controls the operation of the display unit, and a biosignal amplification unit that inputs and amplifies a biosignal detected by an electrode attached to a human body and sends out an amplified biosignal. And a processing unit for inputting a signal from the switch unit and the biological signal amplifier to perform a processing operation and send a display control signal to the display control unit. The operation panel and the processing unit It is configured by connecting and with a connecting cable.

 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 a processing unit (host) 9, and the switches 3a to 3c. The signal from is encoded and transferred to the processing unit 9. 6 is a liquid crystal display control unit,
Upon receiving a signal from the processing unit 9, the display of characters and symbols on the liquid crystal display panel 2 is controlled. Reference numeral 7 denotes an electrode for adhering to the human body to detect and input a biomedical signal, and 8 denotes a processing unit 9 that amplifies the biosignal detected by the electrode 7 through an electrode cable (see FIG. 2) and It is a bio-signal amplification unit for sending to. The switch unit 3, the liquid crystal display control unit 6, the switch control unit 10, and the biological signal amplification unit 8 of the liquid crystal display panel 2.
Is housed in one box and constitutes the operation panel 1, the processing section 9 is housed in another box, and the operation panel 1 and the processing section 9 are connected by a connecting cable. To be done.

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

In FIG. 2, 1 is an operation panel 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 interfacing with a processing section,
5 is an electrode cable for transmitting a biological signal, and 7 is an electrode provided at the tip of the electrode cable. The liquid crystal display panel 2 displays characters and symbols according to signals from the processing unit 9 (see FIG. 1). The switch unit 3 includes switches 3a to 3c (first switch).
A signal is output to the processing unit 9 by pressing (see the drawing). A cable for transmitting / receiving a signal to / from the processing unit 9 is connected to the connection unit 4. The electrode cable 5 is a cable for inputting a minute signal obtained from the living body by the electrode 7 to the operation panel 1.

FIG. 3 is an external view showing a mounting state of the embodiment of FIG. 1 on a human body.

In FIG. 3, the processing unit 9 is attached to a belt or the like and attached to the waist of the human body. The biological signal sent through the operation panel 1 is input and analyzed, and the processing unit 9 is transmitted to the operation panel 1. Sends and receives display signals and control signals. The operation panel 1 can be fixed to an arbitrary place of clothes with a fastener, or stored in a chest pocket or the like, taken out when necessary, and easily operated.

Therefore, since the operation panel 1 is not restricted by the place where it is attached, the display is easy to see and the operation of the keys is easy. Further, since the distance from the electrode 7 which is a biosignal input sensor to the biosignal amplifier 8 in the operation panel 1 can be shortened to amplify a minute biosignal (the biosignal amplifier is conventionally included in the processing unit. In addition, it is possible to obtain a high quality signal with less influence of noise from the outside. Further, since the liquid crystal display panel 1 and the switch unit 3 are not restricted by the device recording / analyzing capacity of the processing unit 9, the size can be made larger than the conventional one. Since the area of the panel 2 can be increased, the amount of information transmitted from the processing unit 9 and displayed can be increased, and the size of the liquid crystal display panel 1 and the switch unit 3 can be determined by the device recording analysis of the processing unit 9. Since it does not affect the capacity, the processing unit 9 can be made small in size and can be easily carried.
