The present disclosure provides, as a film structure useful for a probe of a biosensor, a film structure comprising a detection layer including an analyte-responsive enzyme; and a protection film formed on the detection layer, in which the protection film includes a copolymer mixture including poly(styrene-ran-4-vinylpyridine-ran-propyleneglycol methacrylate); and poly(4-vinylpyridine)-block-poly(Calkyl methacrylate), or poly(4-vinylpyridine-ran-2-hydroxyethyl methacrylate).

Protective film material for biosensor probe

A sensor insertion device comprises a main body, needle slider, disposal slider, spring, puncture knob, and opening mechanism (window member and handle). The needle slider grips a needle and a sensor on a first end side, and is slidable inside the main body. The disposal slider is slidable inside the main body. The puncture knob has an insertion hole into which the rear end portion of the needle slider can be inserted. The opening mechanism puts the insertion hole into a closed state when the needle slider is being slid in the sensor insertion direction, and, puts the insertion hole in an open state in which the second end side of the needle slider has been inserted into the insertion hole by opening up the contact portion between the puncture knob and the second end side of the needle slider when the puncture operation is complete.
