採血装置。 In a blood collection device that is equipped with a blood collection chamber that is depressurized by a vacuum pump and in which a blood container is set, and that collects blood into the blood container using the negative pressure generated in the blood collection chamber, piping that leads from the inlet of the vacuum pump to the blood collection chamber. A pressure regulating device is interposed in the pressure regulating device, and the pressure regulating device includes a housing forming a pressure regulating chamber communicating with the piping, and a valve body that can open and close an air inlet provided in communication with the pressure regulating chamber of the housing. An elastic body that applies either an elastic force in the opening direction or an elastic force in the closing direction to the valve body against the negative pressure of the pressure adjustment chamber, and an adjustment mechanism that can adjust the elastic force of the elastic body. and a valve body drive mechanism for forcibly opening the valve body.
