Problems solved by technology

Transfusions using banked blood supplies can increase the risk of acute or delayed hemolytic reactions, anaphylaxis, purpura after transfusion, and transfusion-associated acute lung injury (TRALI)
Also, some patients refuse to use banked blood for transfusion due to philosophical or religious reasons

Embodiment Construction

[0017] In one exemplary aspect, systems and methods are provided for recovering blood cells of a patient from blood-soaked absorbent materials used during surgical procedures. In the following description, absorbent material may include, but is not limited to, sponge, gauze, tape, cloth, felt, or any other material (including materials made of natural or synthetic fibers) capable of absorbing blood or body fluids, or both blends. Two exemplary absorbent materials are Cottonoid(TM) supplied by Codman and Shurtleff, Inc., Raynham, MA, USA; Spetzler Neruo Patties supplied by OMT, LLC, Ft. Lauderdale, FL, USA. In general, the disclosed systems and methods provide the ability to extract blood from blood-soaked surgical material and deliver the blood to a cell recovery machine, such as a Cell Recovery (TM) device.

[0018] figure 1 is a system 100 for extracting blood from absorbent material according to one embodiment. The system 100 includes a tank 110 having a fixed perforated...

Abstract

Systems and methods are described for salvaging red blood cells from patients during a surgical procedure. In one general aspect, a system is described for extracting blood from blood-soaked absorbent surgical materials such as surgical sponges, gauze, tape, and the like. The collected blood and fluids from these materials can be transferred to a cell salvage machine for harvesting viable red blood cells for autotransfusion.

Description

technical field [0001] The present disclosure relates to systems and methods for blood cell recapture for autologous transfusion during surgery. [0002] References to related applications [0003] This application claims the benefit of Provisional Patent Application Serial No. 61 / 683,315, filed August 15, 2012, entitled "System and Method for Blood Recovery from Absorbent Surgical Materials," pursuant to 35 U.S.C. § 119(e ) claims priority and is hereby incorporated by reference in its entirety. Background technique [0004] Autotransfusion is a practice used in a surgical setting in which a person receives their own blood for transfusion, rather than banked donor blood. This approach reduces the risk of infection (eg, HIV, hepatitis C, cytomegalovirus, bacterial infections, and other transmissible infections) from banked blood supplies and is often used for procedures where the use of homologous blood is contraindicated During and after surgery. Transfusions using bank...
