Abstract

PURPOSE:To constantly measure fluctuation in the physio-chemical quantity of vital fluids by loading a bioterminal into a tooth from which a diseased part is excised or into the drilled portion of a sound tooth. CONSTITUTION:A bioterminal comprises a sensor 2 connected to the input side of a transmitter 3 via a lead wire 4 and the power source 3 of the transmitter 3 brought into contact with a charging terminal 5a via the lead wire 4, and is flexible. The surface of the sensor 2 is directly put in the hole of a drilled tooth to be in contact with the gums l and the charging terminal 5a is buried therein while being exposed to the drilled tooth surface at the upper portion of the tooth. Electric waves(w) from the transmitter are received by a receiving unit via the antenna 12a of the receiving unit. It is therefore possible to constantly measure fluctuation in the physio-chemical quantity of vital fluids.

2. Description of the Related Art In recent years, awareness of health management has increased, and various types of health test equipment have become widespread. However, with these test equipment, the human body is restrained during the examination, so that the human body is not restrained. It is impossible to deal with diseases by constantly receiving information from tests.

Therefore, for example, a ring incorporating an inspection for detecting biometric information and a transmitter for transmitting the biometric information obtained by this is proposed in Japanese Patent Application Laid-Open No. 57-11633. However, since it is the skin of the human body that comes into contact with the ring, biological information such as blood pressure, body temperature, and pulse can always be confirmed, but it is difficult to obtain information such as biological fluid such as blood glucose level.

It has also been proposed in Japanese Patent Laid-Open No. 63-31638 to provide a heating means for causing sweating so that the sensor can detect the sweat so that the detection result can be known. However, it is difficult to wear this on the human body at all times, and it is impossible to detect it in blood, lymph, or meat. Therefore, detection in these departments must be done by the conventional method. For example, when blood is used as a subject, a blood collecting needle, a catheter, a sensor, or the like must be inserted into a living body at the time of inspection. As a result, information regarding the disease cannot always be obtained, and in addition, infection, blood loss, and mental and physical distress to the patient are involved.

On the other hand, a biological terminal is disclosed in Japanese Patent Laid-Open No. 63-9435.
It is taught in the publication. This is to electrically connect the inside and outside of the living body by embedding one end under the skin, projecting the other end on the skin of the living body, and inserting a conductive member into the through hole penetrating the axis of the living body terminal. By connecting the sensor provided at the tip of the conductive member to the external measuring device connected to the other end of the conductive member, the sensor is used for diagnosing or treating a living body. However, since this biomedical terminal is buried under the skin for a long period of time and its head is projected on the skin, it cannot be buried unless the skin is damaged and the head is projected on the skin. May cause trouble,
Physical and mental distress is great, and because it connects with an external measuring device,
It has the disadvantage of having to go to the location of the measuring device.
