Abstract

Ensemble daiguille comprenant un logement transparent ou translucide avec une extrémité dentrée de fluide, une extrémité de sortie de fluide, une chambre de refoulement et un mécanisme daération intercalé. Des canules dentrée et de sortie sensiblement alignées axialement partent du logement et communiquent avec la chambre. Un manchon scellable couvre lextrémité externe de la canule de sortie. Les volumes relatifs des canules, de la chambre et du manchon sont sélectionnés pour permettre un refoulement rapide et fiable indiquant lentrée dans la veine. De plus, un bouchon daération interne est prévu dans la sortie de la chambre de refoulement pour empêcher que le sang ne séchappe de l'aiguille lorsquelle ressort du patient.
