Abstract: The brain function measurement apparatus comprises a plurality of measurement probes; a holder which is fitted to the head of a subject and comprises a plurality of probe attachment parts; a light blocking member which is arranged so as to cover the holder and blocks light from entering the plurality of probes; and a contact prevention member which prevents the light blocking member from contacting the measurement probes.

Abstract: A reaction container kit in which a judgment can be made easily whether a sample is not yet injected or injected already while a sample is prevented from being injected into an incorrect reaction container erroneously. Before a sample is injected, the bar code (132) of a first bar code label is read out by means of a bar code reader and a judgment is made automatically whether that reaction container is a reaction container for the inspection items requested for the sample to be injected or not. If that reaction container is a correct one, the first bar code label (130) is peeled off and a sample is injected into a sample container (32). Subsequently, a second bar code label (134) is stuck onto the sample container (32). Consequently, an opening (31) is sealed hermetically with the second bar code label (134) and the sample is isolated from the outside under a state where the sample is introduced into the space of the reaction container covered with a cover (24).
