摘要:
Die Erfindung betrifft einen Filter zum Filtern einer Flüssigkeit oder eines Gases mit einem taschenförmigen Filterelement, welches einen hülsenförmigen Umfangsbereich, einen geschlossen Kopfbereich und einen offenen Fußbereich aufweist, und einem Rahmenelement, welches einen ringförmigen Sockel, in welchem der Fußbereich des Filterelementes aufgenommen ist, und mindestens eine Stützstrebe aufweist, welche sich von dem Sockel weg entlang des Umfangsbereiches des Filterelementes erstreckt. Eine vorteilhafte Gestaltung des Filters wird dadurch erreicht, dass der Kopfbereich des Filterelementes sattelförmig ausgebildet ist, wobei zwei seitliche Spitzen vorgesehen sind, zwischen denen eine rinnenförmige Auskehlung ausgebildet ist.
摘要:
Eine Filtereinhchtung (1) weist einen als Fluidleitung geeigneten rohrförmigen Filtermantel (4) auf, welcher zumindest eine Eintrittsöffnung (2) für zu filterndes Rohfluid (RO) und eine Austrittsöffnung (3) für gefiltertes Reinfluid (RE) hat. Dabei trennt in dem Innenraum des Mantels eine Grenzfläche (5) aus einem flexiblen Filtermaterial einen Rohfluidbereich (6) von einem Reinfluidbereich (7), und die Grenzfläche (5) ist derart ausgestaltet, dass das Rohfluid (RO) beim Durchströmen der Filtereinrichtung (1) zumindest teilweise radial aus dem Rohfluidbereich (6) in den Reinfluidbereich (7) tritt.
摘要:
A method for manufacturing filtration units (2), for example for biomedical use and the like, constituted by a box-like enclosure (3) and a filtration element (4) which can be mutually assembled, comprising a step of injecting a retention element (6) in the fluid state in a seat (5), which is associated with the box-like enclosure, for accommodating the filtration element (4); a step of embedding an end of the filtration element (4) in a portion of the retention element (6) kept in the fluid state; and a step of consolidation of the retention element (6) in order to lock the filtration element (4) in the seat (5), the retention element (6) being a thermoplastic polymeric material which can be applied by hot injection in a preset closed volume of the seat (5).
摘要:
A device for protecting medical apparatus from contamination by infectious agents comprises a containment body having an inlet (5) destined to be set in fluid communication with an extracorporeal circuit (3) of blood, and an outlet (6) destined to be connected to a fluid line operatively connected to a pressure gauge of a medical apparatus (4). The inlet (5) is in gas communication with the outlet (6) across an internal cavity (11) of the containment body. Two hydrophobic membranes (12, 13) are predisposed in the containment body between the inlet (5) and the outlet (6). The membranes (12, 13) each define an anticontamination barrier which is gas-permeable. The device transmits the pressure of the extracorporeal circuit to the pressure gauge, with no relevant loss of head, while at the same time protecting, with a high degree of security, the medical apparatus (4) from risks of contamination by pathogens originating in the extracorporeal circuit.
摘要:
A filter device inserts into a duct having flow passing from upstream to downstream. The filter device includes fluted filter media having flutes (24) formed therein. The filter forms a seal between the outer edge of the filter and the downstream side of the duct. The filter media may be rolled or stacked in layers to match the shape of the duct.
摘要:
A coupling is provided having filters (106, 120) in the coupler (15) and/or the nipple (66) members. The coupler filter (106) resides in the inlet to the coupler (15) and the nipple filter (120) resides in the inlet to the nipple member (66). The coupler and nipple filters (106, 120) are easily replaced due to their locations and the means employed to secure them in place. The coupler and the nipple filters (106, 120) are high strength stainless steel in the range of 40 to 250 microns.
摘要:
A liquid filtration device (129) useable for removing leukocytes from blood contains a first chamber (108) which is in fluid flow relationship with a second chamber (109). Filtration elements (103) separate the first chamber (108) from the second chamber (109) so that the liquid flowing from the first chamber (108) is filtered thereby prior to entry into the second chamber (109). A passage (111) leads from the second chamber (109) into the first chamber (108) and a hydrophobic filter (104) is used to prevent liquid from the first chamber (108) from flowing through the passage (111) into the second chamber (109) while allowing air to flow therethrough. An outlet (123) is located in the second chamber (109). A second outlet (124) is located within the second chamber (109) and is placed in fluid flow relationship therewith by a conduit (116).
摘要:
An assembly is provided of filter bowl (10), cartridge (12) and head (11) in which the filter bowl (10) can be removed after it has descended from the filter head (11) through a distance corresponding to only a minor part of the length of the filter cartridge (12). The cartridge (12) is a push fit into a vertical port (52) in the filter head (11). Flange (18) of the cartridge (12) and slotted buttress (44) of the bowl (12) establish a mechanical connection between the filter bowl (10) and the filter cartridge (12) so that the filter bowl (10) and the filter cartridge (12) are together mountable to and demountable from the filter head (11). The filter cartridge (12) having the support flange (18) that coacts with the buttress (44) is also claimed per se.
