An autotransfusion system for collecting blood from a patient and reinfusing the blood back into the patient is disclosed. The system includes a collection unit, a manually operable portable suction evacuator removably connected to the collection unit, and a blood reinfusion bag removably connected to the collection unit. The collection unit includes a collection chamber that is oversized relative to the volume of blood that the unit is intended to contain, and an airflow port located and oriented in the collection chamber to prevent blood from leaking into the port when the collection unit is oriented upright or on its side. When connected to the patient, the collection unit and portable suction evacuator are maintained free of blood by enclosing them within a substantially transparent, flexible envelope. The envelope enables the unit and evacuator to be connected and set-up for proper operation while preventing blood from contacting the outer surfaces of the unit and evacuator.

[ Having thus described the invention what we desire to claim and secure by Letters Patent is:] [1.] A collection device for collecting body fluids comprising:a container defining a collection chamber having a defined volume, the container having front and back walls, each of which defines a stable platform by which the container is self-supporting in a generally horizontal attitude;a liquid inlet in communication with the interior of the collection chamber through which body fluids can flow into the collection chamber;a liquid outlet in communication with the interior of the collection chamber to enable collected liquids to be drawn from the collection chamber;an airflow port disposed within the collection chamber, the airflow port being selectively connected to a source of suction or to air at atmospheric pressure;the container being configured so that a reference plane can extend along and between the front and back walls, the reference plane being located to define, in cooperation with the walls of the collection chamber, a volume that is no less than a predetermined subvolume on each side of the reference plane;the airflow port having an orifice disposed within the collection chamber along the reference plane such that when the container is being supported in a generally horizontal attitude by a stable platform-defining wall, the orifice is disposed above the horizontal free surface of a volume of liquid in the chamber that is no greater than the predetermined subvolume.
