[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a biological signal detection device, and in particular, in a monitor device that remotely processes a biological signal detected by an electrode attached to a biological tissue surface of a patient, transmits the obtained signal wirelessly by a transmitter, and is remotely arranged. The present invention relates to a biological signal detection apparatus that can be applied to a medical telemeter system configured to receive this signal and monitor a patient's condition, and a Holter electrocardiograph to which this apparatus is applied.
[0002]
[Prior art]
When nursing a critically ill patient such as ICU or CCU that is directly linked 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. In addition, 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, a doctor's room, or the like.
[0003]
From this point of view, in the past, when obtaining emergency information from patients, such as the movement of emergency patients and the bedside of patients in hospitals, etc., collection of necessary data for each monitor installed in the vicinity and its display When displaying, etc., a medical telemeter system that transmits and receives signals wirelessly is simple and effective for capturing signals detected by a biological signal detection device composed of various sensor electrodes mounted on the surface of a patient's biological tissue. Has been used.
[0004]
However, conventionally, as a biological signal measuring device for measuring a biological signal of a patient or the like by telemetry (cordless), a sensor unit constituted by three electrode units for detecting a biological signal, and each electrode of the sensor unit A biological signal measuring device having a transmission unit that transmits a biological signal detected by the unit to a receiving unit provided outside, and a power supply unit that supplies power to the transmission unit, and the transmission unit The transmitter unit is formed so as to be directly detachable by fitting to any one of the three electrode units, and from the three electrode units. The three contact points corresponding to the signal lines form contact points that are flush with each other, and are configured such that biological signals detected by the three electrode units are input to the transmission unit, and the electrodes It was used as a disposable, which is configured for re-using the transmission unit has been proposed (Utility Model Registration No. 2558836 discloses).
[0005]
That is, the biological signal measuring apparatus according to the proposal integrates a transmission unit including a power supply unit into any one of the three electrode units, and a biological signal detected by the plurality of electrode units is input to the transmission unit. In this way, the patient's sense of restraint is remarkably improved, and since there is no signal cable between the transmitter and the sensor, extra connection points are eliminated, and thus stable for a long time. It is supposed that the reliability can be improved.
[0006]
In addition, the existing portable Holter electrocardiograph device is equipped with an infrared communication device, and ECG data can be input to a personal computer without contact, and data can be stored and analyzed easily, or sampled from a patient. The compressed ECG data is transmitted to a remotely located computer using a wireless public network applied to a mobile phone or a personal digital assistant, and is configured to store and analyze data.

For example, it causes annoyance and discomfort when wearing electrodes in a patient. In addition, there is a problem that no improvement or prevention measures are taken into consideration with respect to the occurrence of a malfunction due to the electrode being detached.
[0009]
Further, although 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, information on the patient side and the monitor side is suggested. No specific proposal has been made regarding the configuration of a medical telemeter system that can be exchanged smoothly and easily.
[0011]
Therefore, the object of the present invention is to eliminate the troublesomeness and discomfort when wearing the electrodes in the patient, prevent the occurrence of malfunction due to the electrode being detached, and exchange information between the patient side and the monitor side. An object of the present invention is to provide a biological signal detection apparatus capable of constructing a medical telemeter system that can be performed smoothly and simply.
