摘要:
The present invention relates to a method for determining an effective dose of monochromatic or polychromatic light from one or more light sources to inactivete microorganisms present in a biological fluid, preferably a non-trannsparent fluid. Moreover, there is provided a method for the inactivation of microorganism in a biological fluid in a flow-through-reactor. Moreover, the invention advantageously provides a flow-through-reactor with one or more thermostated light sources. The invention further provides a method of controlling the light sum dose of monochromatic or polychromatic light emitted from one or more light sources to effectively inactivate microorganisms present in a biological fluid in a batch reactor.
摘要:
Methods and systems for collection of blood components, such as plasma, from donors (D). One method includes the steps of collecting a unit of whole blood from a donor (D); forcing the collected blood unit through a plasma separator (90); accumulating the plasma in a container (94); and returning concentrated cells to the donor (D). One system includes a disposable blood collection set (14) and a reusable fixture (12) into which the collection set (14) can be mounted. The fixture (12) is operated by a self-contained energy source requiring no exterior electrical connection or other external source of energy.

Procédés et systèmes de récupération des composants sanguins, tels que le plasma, à partir de donneurs (D). Un procédé consiste à récupérer une unité de sang entier à partir d'un donneur (D), à faire passer de force l'unité de sang récupérée au travers d'un séparateur de plasma (90), à accumuler le plasma dans un conteneur (94) et à retourner les cellules concentrées aux donneurs (D). Un système comprend un ensemble jetable de récupération du sang (14) et un appareillage réutilisable (12) dans lequel l'ensemble de récupération (14) peut être monté. L'appareillage (12) est actionné par une source d'énergie autonome ne nécessitant aucune connexion électrique ou autre source extérieure d'énergie.

Implant assemblies (10) and methodologies provide immuno-protection for implanted allografts, xenografts, and isografts. The assemblies and methodologies establish an improved boundary (34) between the host and the implanted cells. The boundary (34) has a pore size, an ultimate strength, and a metabolic transit value that assures the survival of the cells during the critical ischemic period and afterward. The boundary (34) allows the fabrication and clinical use of implant assemblies (10) and methodologies that can carry enough cells to be of therapeutic value to the host, yet occupy a relatively small, compact area within the host.
摘要:
A material (16) is formed into hollow fiber form, and the surface characteristics of the interior bore is selectively modified in a predetermined fashion by a reactive lumen fluid. Nucleophilic materials, such as regenerated cellulose, can be formed into hollow fibers and simultaneously modified to improve their biocompatibility in accordance with the invention.
