ABSTRACT:
An apparatus for producing vacuum blood collecting tubes comprises a pinhole checker for checking the bottom portion of each of bottomed tubular containers for pinholes, a sprayer for spraying a blood coagulant to the inner surface of the container, an injector for injecting a serum separating agent into the container, an evacuating-closing device for evacuating the interior of the container and applying a stopper to an opening of the container, and container transport devices between these components. The injector comprises a transport container of solid structure formed in a surface thereof with a plurality of bores for inserting tubular containers individually thereinto, a nozzle case having a plurality of serum separating agent injecting nozzles insertable into tubular containers individually, a device for moving the transport container and the nozzle case relative to each other to press the bored surface of the transport container and a nozzle providing surface of the case against each other, and a device for reducing the pressure of a space defined by the pressed surfaces of the transport container and the case.
