ABSTRACT:
A fluid flow control clamp for in-line insertion on flexible fluid tubing is disclosed. A flow-directing member (10) is positioned intermediate a source of sterilized water or other fluid and a medical humidifier. A blocking element (20) is provided within the flow directing member (10) and inlet and outlet ports (12, 14) are provided on either side of blocking member (20). Resilient tubing (16) is attached to inlet, outlet ports (12, 14) of an appropriate length such that it kinks or crimps (18) when relaxed and unactivated, preventing fluid flow through the clamp.
The clamp is activated by insertion of fingers (24) or other opening means within the loop of resilient tubing (16), unkinking the tubing (16), and permitting fluid flow through the clamp. Release of the resilient tubing (16) causes it to resume its normal kinked position, thereby cutting off the fluid flow through the clamp.
A secondary embodiment discloses a spike connector (30) affixed to the flow-directing member (10) for direct attachment of the clamp to the source of sterilized water. The spike connector (30) may be sheathed with a plastic sleeve (32) to protect it from touch contamination.
