Abstract
Methods and systems for reducing bacterial contamination of platelets are disclosed. The methods and systems disclosed herein provide for the processing of a pre-determined volume of whole blood so as to reduce the risk that platelets separated and collected from the whole blood have a reduced risk of bacterial contamination.
Claims25
A method for reducing the risk of bacterial contamination in collected blood platelets comprising:
- a) inserting a needle of a blood processing kit into a donor to access the vascular system of the patient;
- b) withdrawing a first pre-determined volume of whole blood from a donor;
- c) introducing said first pre-determined volume of said whole blood into at least a portion of said blood processing kit;
- d) returning at least substantially said first pre-determined volume to said donor;
- and
- e) withdrawing a second volume of whole blood from said donor.
3 more elements
An automated system for the collection of blood platelets comprising:
- a) a disposable fluid circuit configured for the flow of whole blood and/or a separated blood component therethrough, said disposable fluid circuit comprising at least one venipuncture needle for accessing the vascular system of a donor, a blood separation chamber for separating whole blood into one or more components;
- b) a reusable hardware device configured to receive a portion of said disposable fluid circuit, said hardware device including a separator element, a pump for withdrawing whole blood from a donor, a pump for removing one or more blood components from said separation chamber, valves for selectively diverting and directing liquid flow, and a controller configured to:
- i) monitor the volume of blood withdrawn from the donor;
- ii) selectively control said pumps to effect movement of blood and blood components through said disposable fluid circuit;
- iii) effect withdrawal a first pre-determined volume of whole blood from a donor and a second volume of whole blood from a donor;
- and
- iv) effect collection of platelets only from said second volume of whole blood.
