ABSTRACT:
An aspirator receiver forms part of a blood aspiration system for injecting fluid into a patient and withdrawing undiluted blood. The aspirator receiver has a housing with a passage occluded by a septum and in communication with the blood flow channel through the aspirator system. An aspirator comprises a cannula having a blunt tip surrounded by a shroud, the cannula being in communication with a blood receiving receptacle. The aspirator is applied to the housing with the shroud centering the cannula about and for penetration through the septum of the housing whereby undiluted blood may be withdrawn from the flow channel into the receptacle. Upon removal of the aspirator, the septum occluding the end of a standard vacuum-filled container is penetrated by the cannula whereby blood from the receptacle may be transferred into the container. The housing and container septa are of like external configuration and dimension and the shroud is complementary in dimension to facilitate transfer of the blood from the aspirator system to the receptacle and finally to the container.
