En se référant à la Fig. 2, on voit que le filtre 26 comprend un bottier supérieur 32 avec une entrée 34, un bottier inférieur 36 avec une sortie 38 et une membrane 40 micropore lnterédiaire. Le filtre 26 est disponible chez Gelmn Filters. La membrane 40 (disponible sous la marque de fabrique VRSAPPOR 200) présente une diension de pore de 0,2 micron. Le bottier supérieur 32 comprend aussi des orifices 42 de mise à l'air recouverts par des Membranes 44 portées sur la surfacce inférieure du boîtier 32. Le boitier inférieur 36 comprend des nervures 46 pour supporter la uembrane 40 et pour réaliser entre elles des canaux de drainage dirigés dans Referring to FIG. 2, it can be seen that the filter 26 comprises an upper case 32 with an inlet 34, a lower case 36 with an outlet 38 and an intermediate micropore membrane 40. Filter 26 is available from Gelmn Filters. The membrane 40 (available under the trademark VRSAPPOR 200) has a pore size of 0.2 micron. The upper case 32 also includes orifices 42 for air venting covered by membranes 44 carried on the lower surface of the case 32. The lower case 36 includes ribs 46 for supporting the uembrane 40 and for making channels between them. directed drainage in
l'ouverture vers la sortie 38.the opening towards exit 38.
En se référant à la Fig. 3, le raccord 28 comprend l'aiguille 48, qui présente une extrémité à pointe alguE 50 pour percer une paroi de poche 22 et un passage 52 de flux de fluide mnagé dans Referring to FIG. 3, the connector 28 comprises the needle 48, which has an end with an alga tip 50 for piercing a pocket wall 22 and a passage 52 for the flow of fluid housed in
cette aiguille. L'aiguille 48 est reliée à la chambre de goutte-à- this needle. The needle 48 is connected to the drip chamber
goutte 54 en plastique transparent qui comporte des indices de niveaux 56. Le capuchon 58 peut être raccordé de façon démontable pour couvrir un orifice de mise à l'air dans la base 60, forme d'un seul tenant avec l'aiguille 48. Le couvre-aiguille 62 couvre drop 54 in transparent plastic which has level indices 56. The cap 58 can be dismountably connected to cover an orifice in the base 60, formed integrally with the needle 48. The needle cover 62 covers
l'aiguille 48.needle 48.
L'appareil 10 comprend aussi une poche d'alimentation de solution saline d'amorçage reliée à la ligne 12 d'alimentation de flux sanguin par un filtre et un tube d'alimentation (tous non The apparatus 10 also includes a priming saline supply bag connected to the blood flow supply line 12 by a filter and a supply tube (all not
représentés) similaires à ceux destinés à l'anticoagulant. shown) similar to those intended for the anticoagulant.
En fonctionnement, quand la centrifugeuse 14 est utilisée avec un nouveau donneur, un Jeu de tubes stériles comprenant les tubes 12, 16, 18, 20, 24 et un canal de centrifugeuse (non représenté) sont montés sur la centrifugeuse 14, et le raccord 28 est relié à la poche d'anticoagulant en perforant la poche 22 avec l'aiguille 48 après avoir enlevé le couvreaiguille 62. On relie de façon similaire une poche de solution saline stérile d'amorçage (non représentée). Pendant qu'on enlève le couvreaiguille 62 et qu'on relie le raccord 28 à la poche 22, il est possible que le système hydraulique soit exposé à des bactéries au raccord 28. Toutes les bactéries introduites dans le raccord 28 sont empêchées de passer au-delà du filtre 26, en raison de la dimension de pores de la mbrane 40. Les bactéries sont de cette façon empochées d'être transportées vers la poche 30 de collecte de plaquettes, o elles pourraient dans le cas contraire se multiplier pendant l'emmagasinage des plaquettes. En disposant des filtres et des raccords sur le Jeu de tubes, les alimentations d'anticoagulant et de solution stérile peuvent être expédiées et emagasinées séparément du Jeu de tubes, ce qui simplifie l'expédition, l'emagasinage et la menipulation du Jeu de tubes. De plus, on peut choisir des fluides différents et des volumes de poches différents, selon le besoin particulier d'un donneur, et les solutions et le jeu de tubes peuvent être stérilisés chacun séparément par un procédé le In operation, when the centrifuge 14 is used with a new donor, a set of sterile tubes comprising the tubes 12, 16, 18, 20, 24 and a centrifuge channel (not shown) are mounted on the centrifuge 14, and the connector 28 is connected to the anticoagulant pocket by perforating the pocket 22 with the needle 48 after removing the needle cover 62. A pocket of sterile priming saline solution is similarly connected (not shown). While removing the needle cover 62 and connecting the connector 28 to the bag 22, it is possible that the hydraulic system is exposed to bacteria at the connector 28. All the bacteria introduced into the connector 28 are prevented from passing to the beyond the filter 26, because of the pore size of the mbrane 40. The bacteria are in this way pocketed to be transported to the pocket 30 for collecting platelets, where they could otherwise multiply during the storage of platelets. By having filters and fittings on the Tubing Set, the anticoagulant and sterile solution supplies can be shipped and stored separately from the Tubing Set, which simplifies the shipping, storage and menipulation of the Tubing Set . In addition, different fluids and different bag volumes can be chosen, depending on the particular need of a donor, and the solutions and the set of tubes can each be sterilized separately by a process
sieux adapté à chacun d'eux.sieux adapted to each of them.
L'aiguille de perforation 48 peut être utilisée de multiples Punch needle 48 can be used in multiple
fois pendant une procédure donnée pour relier des poches multiples. times during a given procedure to link multiple pockets.
On peut donc fournir les quantités à la fois d'anticoagulant et de solution saline qui sont réellement nécessaires. Ceci est un avantage par rapport aux poches reliées de façon permenente, qui soit limitent la procédure & la quantité de solution préraccordée soit tendent à surdimensionner la quantité de fluide fournie avec le Jeu, ce qui conduit à la fois à des poids plus élevés et à une perte de fluide. Cette caractéristique peret aussi une flexibilité pour prolonger une procédure qui ne se produit pas aussi rapiderat que prévu en terne de collecte. On peut prolonger la procédure jusqu'à ce que la quanttié souhaitée de composants sanguins ait été collectée, en ajoutant une nouvelle poche d'anticoagulant si nécessaire. D'autres modes de réalisation de l'invention sont compris dans We can therefore provide the quantities of both anticoagulant and saline that are really necessary. This is an advantage over permanently attached pockets, which either limit the procedure & the amount of pre-tuned solution or tend to oversize the amount of fluid supplied with the Game, which leads to both higher weights and loss of fluid. This feature also allows flexibility to extend a procedure that does not occur as quickly as expected in the dump. The procedure can be extended until the desired amount of blood components has been collected, adding a new bag of anticoagulant if necessary. Other embodiments of the invention are included in
le domine des revendications qui suivent. it dominates the claims which follow.
Par exemple, d'autres séparateurs de sang que la centrifugeuse 14 peuvent être utilisés, et l'invention peut s'appliquer à la For example, other blood separators than the centrifuge 14 can be used, and the invention can be applied to the
