Patent ID: 8043580

Claim:
A testing device comprising: a transparent molded body comprising: a storage chamber for injecting/holding a liquid sample; a plurality of reaction chambers for causing a reaction of the liquid sample, wherein the storage chamber and the reaction chambers are in communication with each other via a distributing flow path; a receiving chamber for receiving the liquid sample, wherein the reaction chambers and the receiving chamber are in communication with each other via a sucking flow path; a sucking port located in the receiving chamber for sucking the liquid sample, wherein the liquid sample is distributed from the storage chamber to the reaction chambers via the distributing flow path by a suction provided by the sucking port; a liquid reservoir for each of the reaction chambers and located between each of the reaction chambers and the receiving chamber; and a through flow path connecting the distributing flow path and the sucking flow path, wherein the liquid sample remaining in the distributing flow path is replaced by air and introduced into the receiving chamber via the through flow path by a further suction provided by the sucking port so as to make the reaction chambers independent from each other.
