Abstract

In apparatus for receiving and reinfusing a patient's own blood, a rigid container encloses a readily deformable inner container, blood being drawn into the readily deformable container by suction and being displaced therefrom by pressure applied between the outer container and the inner container, for pressure reinfusion. Alternatively, the apparatus has a concertina-like container which is held in its expanded condition by a support structure during the blood-intake suction phase, the blood being displaced from the container back into the patient by compression of the container. In another alternative form, the container is a concertina-like container with a high degree of resiliency adapted to expand it into an expanded condition, the container drawing blood from the patient by being compressed before being connected to the patient and then sucking the blood into the container by expansion under the effect of the resiliency.
