Measuring instrument

Abstract

The present invention provides a measuring instrument which enables improvement in contactability of a measuring surface of a sensor with respect to a surface of an object. The measuring instrument (1) is provided with a body part (11) and a probe part (12) that has a head portion (21) at a leading end thereof and an arm portion (22) for connecting the head portion (21) to the body part (11). The head portion (21) has a support section (31), a measuring section (33), and a coupling section (32). The support section (31) is connected to the leading end of the arm portion (22). The measuring section (33) has a first surface (33a) out of which a measuring surface (40a) of a sensor (40) is exposed; and a thickness with the first surface (33a) set as the reference. The coupling section (32) is disposed between the measuring section (33) and the support section (31) so as to couple between the measuring section (33) and the support section (31). The coupling section (32) is made of a soft material and has a first connection portion (32a) which is connected to the measuring section (33); and a through-hole (32c).

Description

technical field [0001] The present disclosure relates to assay devices. Background technique [0002] Conventionally, there has been, for example, an oral moisture meter as a measuring device that is held by a measurer's hand to measure an object (for example, refer to Patent Document 1). This oral moisture meter has a capacitive sensor at the tip of the probe, and measures the water content of the object by pressing the measurement surface of the sensor in parallel to the surface to be measured such as the tongue mucous membrane of the object. [0003] Patent Document 1: International Publication No. 2004 / 028359 [0004] However, it may be difficult for a subject to be measured to stick out his tongue. For such a subject, it may be difficult to insert the tip of the probe into the oral cavity or to press the measurement surface of the sensor parallel to the tongue in the oral cavity in the measuring device described above. If there is an angle between the measurement sur...

[0004] However, it may be difficult for the subject to be measured to stick out his tongue

For such a subject, it may be difficult to insert the tip of the probe into the oral cavity or to press the measuring surface of the sensor parallel to the tongue in the oral cavity in the above measuring device.

If there is an angle between the measuring surface of the sensor and the surface of the object, there is a possibility that the value of the measurement result will be deviated.
