Abstract
A device and method for aspirating fluid from a body cavity are disclosed herein. The device disclosed utilizes a reservoir in fluid communication with a needle via a tube connected to a pump. The needle is able to displace a desired distance. Further, the aspirator includes a selector switch capable having three positions. In the first position anticoagulant is pumped through the system. In the second position bone marrow is aspirated but the needle is not moved. In the third position the displacement of the needle is controlled as well as the volume in the reservoir. Further, in the third position, the volume in the reservoir and the needle displacement are proportional to one another.
