Abstract
The present invention relates to a connector device to connect a first and a second fluid container, directly or indirectly. The connector device exhibit a first and a second connection means, a pierceable barrier member, a piercing member, a fluid transfer channel and a pressure normalization channel. The pressure normalization channel is arranged to normalize an increasing pressure inside second fluid container. A valve arrangement permitting fluid to flow in a first and a second direction is arranged in the pressure normalization channel. The valve arrangement exhibit a cracking pressure in at least the first direction. The present invention provides for a connector device which reduces the risk of clogging the barrier filter.
Claims14
A connector device for establishing fluid communication by connecting a first fluid container with a second fluid container, said connector device comprising
- a housing, said housing comprises first connection means having a pierceable barrier member, connect said first fluid container to said housing, and second connection means, to connect said second fluid container,
- and a fluid transfer channel to enable fluid transfer between said first and second fluid container after assembly,
- said housing further comprises at least one pressure normalization channel arranged to normalize the pressure in said second fluid container during said fluid transfer,
- said at least one pressure normalization channel having an outlet opening, an inlet opening, a barrier filter and at least one valve arrangement,
- wherein
- said at least one valve arrangement is arranged to permit fluid to flow in a first and a second direction, wherein said first direction is in a direction from said inlet opening towards said outlet opening and said second direction is from said outlet opening towards said inlet opening,
- and wherein said at least one valve arrangement has a cracking pressure in at least said first direction.
