Abstract: A pretreatment method and an in-vivo component measuring device in which problems caused by bubbles is suppressed is provided. The pretreatment method uses an electrode sensor 21 for measuring a measurement target component contained in a measurement sample collected from a subject, and a liquid used for pretreatment of measurement, the pretreatment includes step (A) for forming a droplet 8 of liquid, step (B) for pressing the droplet 8 of liquid onto the surface of the electrode type sensor 21 by relative movement of the droplet 8 of liquid and the electrode type sensor 21, and step (C) for removing the droplet 8 pressed against the surface of the expression sensor 21.

Abstract: Provided are a cell imaging device and a cell imaging method that can shorten the time period of taking images of cells in a liquid sample, compared with conventional techniques. This cell imaging device introduces a urine sample containing cells into an internal space of a sample cell, moves at least one of the sample cell and an objective lens in a second direction while at least one of the sample cell and the objective lens is moved in a first direction, the second direction being different from the first direction, and takes, at a plurality of imaging positions, images of cells contained in the urine sample by means of an imaging unit.
