It is a living body monitor fixture characterized by comprising a ring-shaped object that can be positioned at a position. With such a configuration, the probe of the eardrum thermometer is always fixed toward the eardrum, so that accurate body temperature monitoring is possible.

The base portion is preferably made of a hard material for fixing the probe and may be made of metal, but a resin material such as hard polyurethane is preferable in consideration of contact with the skin.

Also, the size of the fitting hole is preferably slightly smaller than the fixed portion of the probe, and the depth thereof is 2 to 2.
About 5 mm is good, if it is less than 2 mm, the probe cannot be fixed well, and if it exceeds 5 mm, the base part becomes thick,
This is not preferable because it gives an unpleasant feeling to the person to be measured.

When fixing the ring-shaped object to the auricle,
It may have any shape, and it does not need to be connected like a ring and may be partially cut. Further, although it may be formed integrally with the base portion, it may be formed as a separate member. In this case, the base portion may be made of resin, and the ring may be made of metal such as wire or metal coated with resin. By deforming the metal, the metal can be deformed according to the shape of the pinna of the person to be measured, and it is possible to firmly fix the pinna. The cross-sectional shape is preferably circular,
