Abstract
A cell inspection method includes a concentrate production step, a staining step, a cell precipitation step, and an observation step. In the concentrate production step, the cell concentrate is produced by causing an inner cylinder which has a filter provided on a bottom surface to enter from the bottom surface side into the through hole of the outer cylinder and bringing the inner cylinder closer to the slide, the inner cylinder having an internal space, and in the observation step, observation is performed in a state where the inner cylinder is entered into the outer cylinder.
Claims17
A cell inspection method for inspecting cells contained in a cell suspension by using a light source and an observation unit, the cell inspection method comprising:
- a concentrate production step of injecting the cell suspension into a chamber formed of an outer cylinder and a slide, and producing a cell concentrate, the outer cylinder having a through hole;
- a staining step of staining the cells on the slide;
- a cell precipitation step of precipitating the cells on the slide;
- and
- an observation step of observing the cells on the slide by the observation unit while illuminating the cells with the light source,
- wherein in the concentrate production step, the cell concentrate is produced by causing an inner cylinder which has a filter provided on a bottom surface to enter from the bottom surface side into the through hole of the outer cylinder and bringing the inner cylinder closer to the slide, the inner cylinder having an internal space, and
- in the observation step, observation is performed in a state where the inner cylinder is entered into the outer cylinder.
A cell inspection device that inspects cells contained in a cell suspension, comprising:
- an outer cylinder which has a through hole and is arranged on the slide, the through hole of the outer cylinder and a slide forming a chamber;
- an inner cylinder that has an internal space, and is capable of being inserted into the through hole of the outer cylinder, a filter being provided on a bottom surface of the inner cylinder;
- a staining solution injector which injects a staining solution into the chamber in a state where the cells is concentrated;
- and
- an observation unit that is provided on a side opposite to a side in which the outer cylinder is provided with respect to the slide,
- wherein in a state where the cell suspension is accommodated in the chamber, a concentration of the cells is executed in a state where the inner cylinder is entered from the bottom surface side into the through hole of the outer cylinder and approaches the slide and
- in a state where the cells are stained by the staining solution and precipitated on the slide, observation of the cells by the observation unit is capable of being executed in a state where the inner cylinder is kept as entering into the outer cylinder.
A cell inspection device that inspects cells contained in cell suspension,
- comprising:
- a base plate;
- an outer cylinder that has a through hole and is arranged on a slide;
- an inner cylinder that has an internal space, and is capable of being inserted into the through hole of the outer cylinder, a filter being provided on a bottom surface of the inner cylinder;
- and
- a light source;
- and
- an observation unit that is provided opposite to a side in which the outer cylinder is provided with respect to the slide,
- wherein a chamber for injecting the cell suspension is formed by the slide and the through hole of the outer cylinder,
- the base plate has an observation hole formed therein and has a depression on which the slide is mounted, and
- the filter of the inner cylinder is made of a light-transmitting material, and the light source illuminates cells in the chamber in a state where the inner cylinder is entered into the outer cylinder.
