Abstract
A biochemical analysis apparatus includes a piercer for piercing a cover member, a nozzle that passes through the piercer which has pierced the cover member and suctions a specimen, a liquid surface sensor that detects contact of the nozzle with the specimen, and a controller that drives the nozzle and the piercer, in which the controller provides an error notification upon detection of contact of the nozzle with the accommodation object inside the piercer, and upon detection of a collision of the nozzle with the cover member.
Claims13
A biochemical analysis apparatus that performs a biochemical analysis of a liquid specimen by reacting the specimen and a liquid reagent in a reaction container, the biochemical analysis apparatus comprising:
- an arrangement portion in which an accommodation container is arranged, the accommodation container accommodating an accommodation object which is the specimen or the reagent and including a cover member;
- a piercer configured to pierce the cover member;
- a nozzle configured to pass through the piercer which has pierced the cover member and suction the accommodation object;
- a first sensor configured to detect contact of the nozzle with the accommodation object;
- a second sensor configured to detect a collision of the nozzle;
- and
- a controller configured to drive the nozzle and the piercer,
- wherein the controller is further configured to:
- provide an error notification when the first sensor detects contact of the nozzle with a droplet of the accommodation object inside the piercer, and
- provide an error notification when the second sensor detects a collision of the nozzle with the cover member.
