Abstract
A device for unstopping a stopped specimen vessel that contains a liquid specimen such as blood is equipped with a mechanism which sucks and captures particles floating around the opening of the specimen vessel and prevents contamination of the specimen. The unstopping device grips a vessel and the stopper of the opening of the vessel, and removes the stopper from the opening of the vessel by changing the relative distance between the vessel-gripping mechanism and the unstopping mechanism. The unstopping device is equipped with: suction holes for sucking therethrough the gas which is present around the opening and contains liquid or solid particles; a pipeline which is connected to the suction holes and through which the sucked gas and particles are led downstream; a suction device connected to the pipeline; and a spirally flexed pipeline part disposed between the pipeline and the suction device.
