Patent ID: 8021629

Claim:
An analyzer for analysis of a specimen in a testing chip that includes a micropump connecting section that is connected with a micropump to take in liquid from the micropump and includes a micro flow channel in which a reagent and the specimen are mixed so as to react with each other, the analyzer comprising: a mounting section for mounting the testing chip attachably and detachably thereto; a micropump unit comprising: a testing chip connecting section to be connected with the micropump connecting section of the testing chip which is mounted on the mounting section; the micropump having an inner channel therein; and a first flow channel which has a first end directly connected to an outlet of the micropump and a second end positioned on the testing chip connecting section so as to connect the outlet of the micropump and the testing chip connecting section to feed liquid from the outlet to the testing chip through the testing chip connecting section, when the testing chip is mounted on the mounting section; a pressing mechanism that presses the micropump connecting section and the testing chip connecting section against each other, the connecting sections being connected with each other; a detection device which detects a reaction in the micro flow channel; and a cleaning mechanism which cleans the micropump connecting section and/or the testing chip connecting section, the cleaning mechanism comprising: a gas blower that sends gas to a connecting part between the micropump connecting section and the testing chip connecting section before the micropump connecting section and the testing chip connecting section become separated from each other, wherein the micropump unit further comprises a second flow channel for at least one of sending gas sent out from the gas blower to the connecting part and taking out the liquid from the connecting part, the liquid being pressed by gas sent out from the gas blower, wherein the second flow channel is connected directly to the first flow channel at a connection point positioned downstream of the first end and upstream of the second end in a liquid feed direction, and wherein the testing chip connecting section comprises a contacting surface which keeps liquid-tight by being pressed against a contacting surface of the micropump connecting section by the pressing mechanism.
