Appl. No.:

09/288145

Inventors:

John Rivera - Aurora CO 80015
Son Le - Lakewood CO 80226
Daniel Cheek - Highlands Ranch CO 80126

Roger P. Kaminski - Parker CO 80134

International Classification:

A61M 3700

US Classification:

604 602, 494 43, 494 37, 604 401, 604 611, 604 601, 422 44, 210782

Abstract:

The present invention is a blood separation system that is fully mechanized to collect blood from a patient, separate waste portions of the blood, wash the blood, and redirect the usable portions to a device for reinjecting the usable portions into the patient. The present invention prevents accidental activation of an improper operation that could cause harm to a patient or a shut down of the system by requiring confirmation of each step by an operator. The invention provides screen displays with detailed setup instructions, eliminating the need for secondary documentation that might not be allowed in a surgical environment. The invention also instructs the operator at the appropriate times to do certain manual steps such as opening and closing clamps. Since the opening and closing of clamps is a highly critical operation, confirmation of these steps is also required. A method and suitable apparatus is also disclosed for sequestration of platelet rich plasma whereby a blood sample is spun at a high speed sufficient to separate solid cells from the blood sample and spun at a lower speed for a predetermined time to allow platelets to elute from the solid cells.
