Title
(EN) SAMPLING WITH FITTING BETWEEN NEEDLE AND HOUSING
(FR) ÉCHANTILLONNAGE AVEC UN RACCORD ENTRE UNE AIGUILLE ET UN BOÎTIER
Abstract
(EN) Disclosed is a sampling unit (40) comprises a needle (200) configured for aspirating a sample fluid, a housing (365), and a fitting (370). The needle (200) comprises a needle tip (300) and a needle channel (310) through the needle (200) for guiding the aspirated sample fluid, wherein the needle channel (310) opens at the needle tip (300). The housing (365) comprises a housing cavity (360) and a housing channel (350) opening into the housing cavity (360). The fitting (370) comprises a fitting cavity (375) and a fitting channel (380), wherein the fitting (370) is configured for sealingly receiving the needle tip (300) into the fitting cavity (375) and for being inserted into the housing cavity (360), so that the fitting channel (380) on one side fluidically couples to the needle channel (310) and on another side couples to the housing channel (350).
(FR) Une unité d'échantillonnage (40) comprend une aiguille (200) configurée pour aspirer un échantillons liquide, un boîtier (365) et un raccord (370). L'aiguille (200) comprend une pointe d'aiguille (300) et un canal d'aiguille (310) à travers l'aiguille (200) pour guider le fluide d'échantillon aspiré, le canal d'aiguille (310) s'ouvrant au niveau de la pointe d'aiguille (300). Le boîtier (365) comprend une cavité de boîtier (360) et un canal de boîtier (350) débouchant dans la cavité de boîtier (360). Le raccord (370) comprend une cavité de raccord (375) et un canal de raccord (380), le raccord (370) est conçu pour recevoir de manière étanche la pointe d'aiguille (300) dans la cavité de raccord (375) et destiné à être inséré dans la cavité de boîtier (360), de telle sorte que le canal de raccord (380) sur un côté se couple de manière fluidique au canal d'aiguille (310) et sur un autre côté se couple au canal de boîtier (350).
