Abstract: A method for onsite hemorrhage control in trauma patients using a portable rapid autotransfusion device can involve recovering a first portion of patient blood from an extravascular space into a fluid reservoir of the device. A negative internal pressure can be applied to the blood. The blood can be conditioned, such as by oxygenating and removing carbon dioxide. The conditioned blood can be returned to the patient intravenously at a rate that matches the rate of blood recovery, ensuring that the net volume of returned blood is maintained substantially equal to the net volume of removed blood.

Abstract: A system for performing extracorporeal blood treatment of recovered blood can include a reservoir to receive a first portion of the recovered blood from a subject, an inline pump coupled the reservoir to regulate a flow rate of at least the first portion of the recovered blood, and an extracorporeal blood conditioner including at least one of an oxygenator to reoxygenate hemoglobin included in the recovered blood for at least intravenous delivery back to the subject or a temperature regulator configured to selectively control a temperature of the recovered blood.
