Fluid interface for bioprocessor systems
First Claim
1. An aseptic fluidic interface apparatus between bioprocess systems, comprising:
- an inlet valve, adapted for automatic control, coupled to a biofluid source site;
a sampling conduit extending from the inlet valve to an outlet valve adapted for automatic control, wherein the outlet valve is coupled to a biofluid process site;
a trap, the trap being a portion of the sampling conduit extending from the inlet valve to the outlet valve and having a low region that is lower than the inlet valve and the outlet valve;
a waste valve, adapted for automatic control, that is located at a waste conduit extending from the sampling conduit to a waste site, the waste valve being coupled to the low region of the trap; and
a wash fluid source coupled to at least one of the inlet or outlet valves.

Abstract
An apparatus and method for an aseptic fluidic interface between bioprocess systems is provided. The apparatus includes an inlet valve, adapted for automatic control, that is coupled to a biofluid source site. A sampling conduit extends from the inlet valve to an outlet valve. The outlet valve is adapted for automatic control and is coupled to a biofluid process site. A trap is at the sampling conduit. A waste valve, adapted for automatic control, is located at a waste conduit extending from the sampling conduit to a waste site. Also included is a wash fluid source that is coupled to at least one of the inlet or outlet valves. In the method, the sample is automatically directed to the biofluid process site by opening the outlet valve, and closing the waste valve. Also included is isolating the biofluid sites by closing the inlet and outlet valves, and opening the waste valve to drain biofluid from the trap to the waste site. Another step is cleaning the sampling conduit before sample collection by directing the wash fluid through at least one valve selected from the inlet and outlet valves, and subsequently through the waste valve to the waste site.

25. An aseptic fluidic interface between bioprocess systems, comprising:
-
an inlet valve coupled to a biofluid source site, the inlet valve being a double isolated gate valve that has a first output coupled to a waste site; a sampling conduit extending from a second output of the inlet valve to an outlet valve, the sampling conduit having a trap at a height lower than the inlet and outlet valves, the outlet valve being a double isolated gate valve having a second input coupled to a wash fluid source, and the outlet valve coupled to a biofluid process site at the same height as the inlet valve; a waste valve at a waste conduit extending from the bottom of the trap to the waste site; a relief conduit extending from the waste conduit between the trap and the waste valve to an overflow filter, the filter selected to exclude particulate contaminants greater than about 0.2 μ
