摘要:
The present invention relates to a device for calibration in a method for the inactivation of microorganism in a biological fluid, comprising irradiating the biological fluid with an effective dose of monochromatic or polychromatic light from one or more light sources, wherein the effective dose is determined by measuring the effect of the monochromatic or polychromatic light on a dosimetric solution.

摘要:
A device and method for inactivating pathogens in therapeutic fluids with sterilizing radiation in a continuous flow arrangement while exhibiting radiation dose uniformity and narrow residence time distribution of the fluid within the device. The device (10) comprises a radiation permeable cylindrical tube (12) having a concentric cylindrical rotor (14) disposed therein, thereby providing a thin gap (16) therebetween. A top plate (18) having a fluid outlet (26) and a bottom plate (20) having a fluid inlet (24) seal the cylindrical tube (12). The inlet (24) and outlet (26) are both in fluid communication with the thin gap (16). A rotor shaft (36) is diposed axially through the cylindrical rotor (14) and is connected to a motor (30). A pump provides fluid flow through the device (10). A radiation source provides sterilizing radiation to the fluid through the cylindrical tube (12). As the fluid flows, the motor (30) drives the rotor (14) to impart Taylor vortices to the fluid flow, which exchanges the fluid closer to the cylindrical tube (12) with the fluid closer to the rotor (14).

Permeable structures suited for implanting in host tissue include a first permeable region comprising a polymer solution formed-in-place in contact with a second permeable region. The structures provide enhanced immunoisolation, which promotes the survival of even xenogeneic cells implanted in host tissue.

The apparatus is especially useful for blood separation and includes a variable volume container (86) for receiving blood, a separator (90) for separating the blood into components and force-applying means for forcing blood from the container through the separator back to a donor. The apparatus is self-contained and portable, the force-applying means (34b,24,52) being held by a fixture (12), which also releasably supports the separator (90) and container (86). The force-applying means comprises rechargeable energy storage means such as means for holding a replaceable module (c) of compressed gas which is used to inflate a bladder (34b) to compress the container (86). Electrical and mechanical storage means are alternatives described.
