[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical communication device of a type which automatically notifies a hospital or the like separated from a living body when the living body information detected from the living body is abnormal.

[0002]

2. Description of the Related Art For people who are bedridden at home, or who have illnesses that can be used in daily life but require caution, attach a biometric sensor to the living body to monitor the electrocardiogram, blood pressure, body temperature, blood There has been considered a medical communication device of a type in which biological information such as oxygen saturation and blood sugar level is sequentially detected, and when an abnormality in the biological information is detected, the fact is automatically notified to a hospital or the like. For example, the one described in JP-A-59-77760 is that. In the medical communication device described in this publication, the sensor is for detecting biological information and a wireless transmission circuit is attached to a living body, and the biological information transmitted from the wireless transmission circuit is displayed. A radio receiving circuit for receiving a signal, an abnormality determining section for determining an abnormality of the received biological information signal, and an automatic telephone connection circuit for notifying the social emergency system when the abnormality of the signal is determined It is composed of an installed part.

[0003]

However, in such a conventional medical communication device, a small output circuit is used as a transmitting circuit in order to reduce the size and weight of the mounting portion such as the above-mentioned mounting carrying portion mounted on the living body. Since it is usually used, there is a drawback that the radio wave of the biological information signal transmitted from the transmission circuit becomes weak and the transmission range is narrowed.

Further, even if an abnormality in the biometric information signal is detected, the abnormality may be temporary or due to noise, so that unnecessary notifications may occur frequently. .

Further, even if the abnormality of the biological information is reported to a doctor or the like, it is not constructed so as to give an instruction to the biological body. Therefore, in case of emergency, a temporary medical treatment for the biological body is required. It had the drawback of not being able to give instructions.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to reduce the size and weight of a device equipped with a biometric information sensor and a transmitter and attached to a living body. Even when the radio wave of the biometric information signal transmitted from the transmitter is weak, a wide transmission range can be secured, unnecessary notification of abnormal biometric information can be suitably prevented, and further notification of abnormal biometric information can be reported. It is to provide a medical communication device that allows a doctor or the like to give an instruction to a living body when there is a problem.

[0007]

The gist of the medical communication device of the present invention for achieving the above object is as follows:
A biometric sensor for detecting biometric information from a living body, and a first biometric information signal representing the biometric information transmitted with a weak output
A portable microsensor device equipped with a transmitter and attached to a living body; (b) a first receiver for receiving a biometric information signal from the portable microsensor device; and a first receiver for receiving the biological information signal. And a signal indicating that the abnormality detection device detects an abnormality in the biological information signal and the abnormality detection device detects the abnormality in the biological information signal and the diagnostic result by the diagnostic device is abnormal in the first receiver. An alarm device that gives an alarm when received and an anomaly detection device that detects an anomaly in the biometric information signal causes the biometric information signal received by the first receiver to be output from the first transmitter more than the first transmitter. A second transmitter that transmits with a large output, and an instruction output device that outputs an instruction represented by the instruction signal received by the first receiver, and a monitoring unit that is arranged in the living body or in the vicinity thereof, c) The director A second receiver that receives a biometric information signal from the unit, a diagnostic device that diagnoses the biometric information based on the biometric information signal received by the second receiver, and a diagnostic result by the diagnostic device is abnormal. In some cases, the living body that transmits the biometric information signal received by the second receiver to a predetermined medical worker via a wired line and is transmitted from the medical worker via the wired line. And a third transmitter for transmitting a signal indicating that the diagnosis result by the diagnostic device is abnormal and a third transmitter for transmitting the instruction signal to the monitoring unit. And a diagnostic notification device installed at a place distant from.

[0008]

In the medical communication device having such a configuration, when biometric information is detected by the biometric information sensor of the portable microsensor device attached to the living body, a biometric information signal representing the biometric information is transmitted from the first transmitter. Sent with weak output. The biological information signal transmitted from the first transmitter is received by the first receiver of the monitoring unit, and when the abnormality of the biological information signal received by the first receiver is detected by the abnormality detection device, The biological information signal received by the first receiver is transmitted from the second transmitter of the monitoring unit with a larger output than the first transmitter. The biometric information signal output from the second transmitter is received by the second receiver of the diagnostic notification device, and the diagnostic device diagnoses the biometric information based on the biometric information signal received by the second receiver. Done. When the diagnostic result by this diagnostic device is abnormal, the wired communication circuit of the diagnostic notification device transmits the biometric information signal received by the second receiver to a predetermined medical worker via a wired line. An instruction signal indicating an instruction to the living body transmitted from the medical staff via the wired line is received, and the instruction signal is transmitted from the third transmitter of the diagnostic notification device to the monitoring unit, By being received by the first receiver, the instruction from the medical staff represented by the instruction signal is output from the instruction output device of the monitoring unit. When the diagnostic result by the diagnostic device is abnormal, a signal indicating that the diagnostic result by the diagnostic device is abnormal is transmitted from the third transmitter to the monitoring unit, and the signal is transmitted to the first transmitter of the monitoring unit. When received by, the alarm device of the monitoring unit issues an alarm. The monitoring unit is arranged at or near the living body, and the diagnostic notification device is installed at a place separated from the monitoring unit.

[0009]

As described above, according to the medical communication device of the present invention, even if the radio wave of the biometric information signal transmitted from the first transmitter of the portable microsensor device is weak, the biometric information signal is transmitted. It is transmitted to a diagnostic notification device installed at a place distant from the monitoring unit via a monitoring unit having a second transmitter which is arranged in the vicinity of the portable microsensor device and has an output larger than that of the first transmitter. Therefore, a wide transmission range of the biometric information signal can be secured.

Further, even if an abnormality of the biological information signal is detected by the abnormality detecting device of the monitoring unit, if the diagnosis result of the diagnostic device of the diagnostic notification device is not abnormal, no notification is given to the medical staff. When the abnormality of the biological information in the monitoring unit is temporary or due to noise, it is possible to preferably prevent unnecessary notification of the abnormality of the biological information.

Further, when the diagnosis result by the diagnostic device becomes abnormal and the biometric information signal is transmitted to the medical staff via the wired circuit, the medical staff knows that the condition of the living body is abnormal at the same time. The condition of the living body can be grasped by looking at the biological information represented by the transmitted biological information signal.
In this case, since it is configured that the medical staff can give instructions to the living body via the wired line, the medical staff gives instructions for temporary medical treatment to the living body in case of emergency. can do.

In addition to the fact that the first transmitter of the portable microsensor device outputs a weak signal and is relatively small, the abnormality detection device, the alarm device, and the instruction output device are all Since it is also provided in the monitoring unit and not provided in the portable microsensor device, it is possible to reduce the size and weight of the portable microsensor device attached to the living body, and to appropriately reduce the burden on the living body. You can Note that the monitoring unit is not always attached to a living body like a portable microsensor device, and even when attached to a living body, the mounting position can be freely selected as compared with the portable microsensor device. Therefore, even if the monitoring unit is provided with the above-mentioned abnormality detection device, the burden on the living body does not increase that much.
