Embodiment Construction

[0032] The schematic diagram in FIG. 1 shows the components and structure of a blood component separation system 10 using optical trap technology. The system is used to separate blood passing therethrough to separate one or more constituent components. For example, the separated components may include red blood cells, plasma, or platelet-rich plasma. Additionally, optical traps can be used to separate proteins, infectious proteins, viruses, bacteria and other contaminants, and particulates from blood flowing through the system. In addition, optical traps can also be used to detect the presence of specific or infected cells, such as diseased cells (eg sickle cells), the presence of which would cause a donated blood sample to be rejected. In this application, the various constituents - cells, parts of cells, bacteria, and contaminants - are collectively referred to as "components". It should be noted that the term "component" may refer to any of the components mentioned above ...

Abstract

Provided is a blood processing system having a stationary component separation chamber. Individual blood components as well as other particles and contaminates are separated from blood flowing through the separation chamber by optical traps configured to manipulate specific components are projected into the flow field of the chamber. Cells or particles of the selected components that are manipulated by the optical traps then may be directed from the flow field to individual reservoirs to collect quantities of the selected components.

Description

technical field [0001] The invention relates to blood treatment equipment. In particular, the present invention pertains to systems and methods for separating one or more constituent components from blood using optical traps projected through a static separation chamber. Background technique [0002] Systems and methods for separating blood into its various components are well known. A commercial system for performing rapid processing of large volumes of blood in a continuous flow method is available from Haemonetics, Inc. of Braintree, Massachusetts. In particular, equipment from Haemonetics - such as the MCS Series Devices and Cell Saver Type 5 systems are designed to receive blood directly from a patient or donor, deliver the blood to a blood processing chamber, separate the various components from the blood, and direct the separated components to individual component reservoirs for subsequent use or return to the patient, while the device returns the remaining bloo...
