2. Description of the Related Art When nursing critically ill patients such as ICUs and CCUs that are directly related to life, it is necessary to continuously monitor biological information in order to accurately grasp the patient's condition. For this reason, it is important to use a bedside monitor provided on the patient's bedside to obtain information necessary for treatment performed on the patient's bedside. Also,
It is also important to quickly detect a patient's abnormality and issue an alarm, and to send data obtained from the patient's biological information to a central monitor provided in a nurse station, doctor's office, or the like.

[0003] From such a point of view, conventionally, when moving an emergency patient or obtaining biological information from a patient at a bedside of a patient in a hospital or the like, collecting data necessary for monitors installed around the respective patients. In the case of displaying the display and the like, in order to capture a signal detected by a biological signal detection device including various sensor electrodes and the like attached to the body tissue surface of a patient, a medical telemeter system that wirelessly transmits and receives signals is used. It is simple and effective.

Conventionally, as a biological signal measuring device for measuring a biological signal of a patient or the like by telemetering (cordless) and measuring the signal, a sensor unit including three electrodes for detecting a biological signal, and the sensor unit A transmitting unit that transmits a biological signal detected by each of the electrode units to a receiving unit provided outside, and a biological signal measuring device including a power supply unit that supplies power to the transmitting unit, wherein the transmitting unit is A power supply unit, and the transmitting unit
The three contacts, which are formed so as to be directly detachable by fitting to any one of the three electrode portions, and correspond to signal lines from the three electrode portions,
Forming a contact that makes flush contact with each other, and configuring the transmitting unit to receive biological signals detected by the three electrode units respectively, making the electrode unit disposable, and reusing the transmitting unit. A configuration that can be performed has been proposed (U.S. Patent No. 2,558,836).

That is, in the biological signal measuring device according to the proposal, a transmitting unit including a power supply unit is integrated with any one of the three electrode units, and the transmitting unit detects a biological signal detected by the plurality of electrode units. The arrangement for inputting the signal significantly improves the sense of restraint of the patient, and eliminates extra connection points because there is no signal cable between the transmitter and the sensor. Measurement can be performed stably and reliability is improved.

In addition, an existing portable Holter electrocardiograph is provided with an infrared communication device so that electrocardiogram data can be input to a personal computer in a non-contact manner to easily accumulate and analyze data. It is configured to transmit more sampled and compressed electrocardiogram data to a remotely located computer using a wireless public network applied to a mobile phone, a portable information terminal, etc., and perform data accumulation and analysis. Thus, there has been proposed a Holter electrocardiograph apparatus which can improve the convenience of a communication interface with a computer for analyzing, storing, and organizing data (Japanese Patent Application Laid-Open No. 9-224917).

There is a drawback that simple and quick ECG data cannot be obtained because the position is not set.

In the Holter monitor according to the above-mentioned proposal, an existing portable Holter monitor is provided with an infrared communication device so that electrocardiogram data can be transmitted to a personal computer or a remotely located computer without contact. And send
Since it is intended to smoothly store and analyze data, and not to make improvements to the conventional portable Holter electrocardiograph itself, for example, occurrence of inconvenience and discomfort when attaching electrodes to a patient, In addition, there is a drawback that no improvement or prevention measures are taken into consideration with respect to occurrence of malfunction due to misplacement of the electrodes.

Further, it has been suggested that each of the devices according to the above proposal can transmit a biological signal of a patient by wireless transmission to a remotely located monitor. No specific proposal has been made for the configuration of a medical telemeter system that enables information to be exchanged smoothly and easily.

It is possible to obtain a biological signal detecting device capable of preventing a malfunction due to electrode dismounting and building a medical telemeter system capable of smoothly and easily exchanging information between a patient and a monitor. I found it.

Accordingly, an object of the present invention is to eliminate the trouble and discomfort when the electrodes are mounted on the patient, to prevent malfunctions due to the incorrect mounting of the electrodes, and to allow the patient and the monitor to connect with each other. It is an object of the present invention to provide a biological signal detecting device capable of constructing a medical telemeter system capable of smoothly and easily exchanging information.
