CA 2235217

A container (400) for the collection of fluids in a vacuum system includes upper and lower chambers (402, 404). Fluids are admitted to the upper chamber (402) to form a vortex and separate fluid and debris from air. The fluids then pass to the lower chamber (404) through a filter (412). A discharge tube (428) is connected to the lower chamber (404) to allow the accumulated fluids to be pumped from the container (400). The bottom of the lower chamber (404) includes a recess (430) that forms a platen for a roller pump, and a discharge tube (428) is located adjacent the platen whereby rollers (426) engage the tube (428) and platen upon installation of the chamber (400) on a base. A second port (418) is provided to the upper chamber (402) for admission of a second fluid such as an anticoagulant.

Un récipient (400) permettant de recueillir des fluides dans un système à dépression comprend une chambre supérieure et une chambre inférieure (402, 404). On fait passer les fluides dans la chambre supérieure (402) de façon à former un tourbillon et à séparer l'air du fluide et des débris, puis on les amène dans la chambre inférieure (404) par un filtre (412). Par un système de pompe, on fait sortir du récipient (400), par un tube d'évacuation (428) relié à la chambre inférieure (404), les fluides accumulés. Le bas de la chambre inférieure (404) comporte un enfoncement (430) qui forme une platine destinée à une pompe à rouleaux, et un conduit d'évacuation (428) adjacent à la platine, les rouleaux (426) se fixant sur le conduit (428) et la platine après installation de la chambre (400) sur une base. Un second orifice (418) situé dans la chambre supérieure (402) permet d'introduire un second fluide tel qu'un anticoagulant.
