Abstract
A blood separation chamber comprises a base that includes formed walls that define a hub. A separation channel extends about the hub. A flow passage extends between the hub and the separation channel. The hub enables attachment of external tubing to convey blood to and from the separation channel through the hub.
Claims1
A blood separation chamber comprising
- a formed body, which, in use, rotates about a rotational axis,
- a first interior wall formed on the body, which extends circumferentially about the rotational axis to define a hub,
- inside and outside walls formed on the body, which extend circumferentially about the hub in a spaced apart relationship to define between them a separation channel,
- second interior walls formed on the body, which extend radially from the hub in a spaced apart relationship to define between them at least one passage that communicates with the separation channel to direct blood between the hub and the separation channel, and
- a connector formed on the body to couple exterior tubing to the hub in communication with the passage to convey blood to or from the passage during rotation of the formed base.
