Abstract
A probe assembly for a closed transfer system is provided. The probe assembly includes a base having a base air inlet, a probe having a base end and a probe end, at least one primary valve positioned at the probe tip, and at least one secondary valve. The probe defines a hollow air channel extending from the base end to the probe end including a probe tip, the base end being coupled to the base such that the hollow air channel is in fluid communication with the base air inlet and the probe tip. The at least one secondary valve is positioned at the base air inlet and configured to selectively allow air into the hollow air channel.
Claims20
A probe assembly for a closed transfer system, the probe assembly comprising:
- a base including a base air inlet, a base rinse inlet, and an internal wall;
- a probe having a base end and a probe end, a probe tip positioned at the probe end, the probe defining a hollow air channel extending from the base end to the probe end, the base end being coupled to the base such that the hollow air channel is in fluid communication with the base air inlet and the probe tip;
- at least one primary valve positioned at the probe tip;
- and
- at least one secondary valve positioned proximate the base air inlet, wherein
- the internal wall
- partially defines the base rinse inlet, and
- separates the base rinse inlet from the base air inlet.
A probe assembly for a closed transfer system coupler, the coupler including a housing and a handle, the coupler configured to couple a fluid-filled container into a fluid-tight configuration with the coupler and selectively actuate the probe assembly to protrude at least partially inside of the container by actuation of the handle, the probe assembly comprising:
- a base including a base air inlet, a base rinse inlet, and an interior seat;
- a probe defining a hollow air channel extending from the base to a probe tip, the hollow air channel in fluid communication with the base air inlet and the probe tip;
- at least one primary valve positioned at the probe tip;
- and
- at least one secondary valve positioned at the base air inlet and configured to selectively allow air into the hollow air channel, wherein
- the probe engages the interior seat and fluidly isolates the base air inlet from the base rinse inlet.
A probe assembly for a closed transfer system coupler configured to selectively engage a container coupled to the coupler in a fluid tight configuration, the probe assembly comprising:
- a base including a base air inlet and a base rinse inlet;
- a probe defining a hollow air channel in fluid communication with the base air inlet, the probe including at least one primary valve;
- and
- at least one secondary valve configured to selectively allow air into the hollow air channel, wherein
- the probe is insertably received into the base, and
- the base air inlet is fluidly isolated from the base rinse inlet via an inner tube of the probe being coupled to the base.
