Provided is a biological sample imaging device and a biological sample imaging method that are capable of disposing a sufficient number of large-sized particles in a biological sample so as to be moderately dispersed within an imaging range. The biological sample imaging method includes: a first step of introducing a biological sample containing particles into a liquid flow channel; a second step of causing the biological sample introduced into the liquid flow channel to flow in a forward direction; a third step of causing the biological sample to flow in a reverse direction after the second step; and an imaging step of taking, in an imaging cell, images of the particles contained in the biological sample that remains in the liquid flow channel after the third step.

Biological sample imaging device and biological sample imaging method

A sample preparation device includes: a filter member including a filter configured to separate cells being an analysis target from other components in a sample; a first receptacle and a second receptacle configured to be connected to each other via the filter; a third receptacle capable of holding the sample therein; a negative pressure section configured to apply a negative pressure into the second receptacle, thereby to move the sample in the third receptacle toward the filter via the first receptacle, and thereby to move components other than the analysis target into the second receptacle via the filter; and a positive pressure section configured to apply a positive pressure from the second receptacle side to the filter to which cells being the analysis target are attached.
