Title (EN) IMPROVED STORAGE BAG FOR BLOOD AND BLOOD COMPONENTS
(FR) POCHE AMELIOREE POUR LE STOCKAGE DU SANG ET DE COMPOSANTS SANGUINS
Abstract:
(EN) A bag (10) is disclosed for the collection, freezing, storage, and rapid thawing of fluids, and particularly blood and blood components. Front and back sheets (11, 12) of fluid impervious material are bonded to one another along edge portions (14) thereof, to form a bag (10), defining a reservoir. The front and back sheets (11, 12) are further bonded together at a plurality of locations (60) intermediate the edge portions (14) to constrain the distance by which the front and back sheets can separate. The intermediate fastening locations (60) are disposed to permit uniform filling of the reservoir. A port (30) is provided for introducing and discharging fluid into and out of the reservoir. When a fluid is introduced into the reservoir, the front and back sheets (11, 12) are constrained from separating in response to a pressure exerted by the fluid by the intermediate fastenings (60) between the front and back sheets (11, 12) to constrain the thickness of the bag (10). The distance between the centermost points in the interior of the bag and the corresponding closest points on the exterior of the bag is thereby minimized, increasing the rate at which it is transferred into or out of the bag contents. Heat transfer is thus greatly improved, markedly reducing the time required to freeze or thaw the bag contents.
(FR) Poche (10) servant à collecter, à geler, à stocker, et à dégeler rapidement des fluides, et plus particulièrement du sang et des composants sanguins. Les couches avant et arrière (11, 12) de matière étanche aux fluides sont liées l'une à l'autre en périphérie (14) et constituent ainsi une poche (10) formant un réservoir. Les couches avant et arrière (11, 12) sont en outre liées entre elles en une pluralité d'endroits (60) situés entre les parties périphériques (14) pour restreindre la distance de séparation entre les couches avant et arrière. Les emplacements d'assemblages intermédiaires (60) sont disposés de façon à permettre un remplissage uniforme du réservoir. Un orifice (30) est prévu pour introduire un liquide dans le réservoir et pour le retirer. Quand un fluide est introduit dans le réservoir, les couches arrière et avant (11, 12) ne peuvent se séparer en raison de la pression exercée par le fluide et par les assemblages intermédiaires (60) entre les couches avant et arrière (11, 12); l'épaisseur de la poche (10) est ainsi restreinte. La distance entre les points les plus centraux à l'intérieur de la poche et les points correspondants situés le plus près de la partie extérieure de la poche est réduite au minimum, ce qui accroît le rythme auquel la chaleur est transférée dans ou en dehors du contenu de la poche. Le transfert de chaleur est ainsi considérablement amélioré, et le temps nécessaire pour geler ou dégeler le contenu de la poche est sensiblement réduit.
