Abstract
Official abstract text for this publication.
A centrifuge bowl for separating whole blood into blood components includes a rotatable body, and inlet, and a plurality of vibration reduction members. The rotatable body has a body portion and a neck portion. The body portion defines an interior for receiving whole blood, and the body is rotatable to separate the whole blood into a plurality of blood components. The inlet is in fluid communication with the interior of the rotatable body, and is configured to introduce the whole blood into the rotatable body. The plurality of vibration reduction members are spaced about the neck portion, and are configured to reduce vibration of the centrifuge bowl as the bowl is rotated.
First claim
Opening claim text (preview).
What is claimed is: 1 . A centrifuge bowl for separating whole blood into blood components comprising: a rotatable body having a body portion and a neck portion, the body portion defining an interior for receiving whole blood, the body being rotatable to separate the whole blood into a plurality of blood components, the body portion also having a shoulder portion extending between the body portion and the neck portion; an inlet in fluid communication with the interior of the rotatable body, the inlet configured to introduce the whole blood into the rotatable body; and at least one vibration reduction member located on the shoulder portion and configured to stiffen at least a portion of the rotatable body and reduce vibration of the centrifuge bowl as the bowl is rotated. 2 . A centrifuge bowl according to claim 1 wherein the at least one vibration reduction member includes a plurality of rib members. 3 . A centrifuge bowl according to claim 2 , wherein the rib members are curved. 4 . A centrifuge bowl according to claim 2 , wherein the rib members are straight. 5 . A centrifuge bowl according to claim 2 , wherein the at least one vibration reduction member includes a thickened area located on the shoulder portion. 6 . A centrifuge bowl according to claim 5 , wherein the thickened area increases in thickness towards an axis of rotation of the bowl. 7 . A centrifuge bowl according to claim 6 , wherein the increase in thickness is stepped. 8 . A centrifuge bowl according to claim 1 , wherein the rotatable body is frustoconical.
