Devices and methods for fluid infusion, drainage, and collection

A container for collecting fluid, comprising:

• a reservoir comprising a plurality of panels enclosing an interior thereof, the panels comprising side panels generally opposite one another that are movable from an expanded position towards one another to a compressed position and biased to the expanded position for generating a vacuum within the interior;
• an elongate housing comprising a valve device extending along a top side of the reservoir and comprising a proximal end, a distal end, and a passage between the proximal and distal ends communicating with the interior of the reservoir, the valve device comprising an elongate member having a proximal end, a distal end, and a lumen therethrough extending between the proximal and distal ends of the valve device, and at least two ports communicating with the elongate member;
• wherein the elongate member communicates with a distal one-way valve and the passage;
• wherein the distal one-way valve is coupled to the elongate member permitting fluid flow proximally from the valve device while preventing fluid flow distally;
• a proximal extension having a proximal and distal end with a lumen therethrough coupled to the proximal end of the elongate housing communicating with the passage;
• and
• a proximal one-way valve coupled to the proximal extension for permitting fluid flow proximally from the proximal extension while preventing fluid flow distally into the proximal extension and lumen.

A method for collecting fluid within a container, comprising:

• providing a container comprising a reservoir defining an interior and compressible to from an expanded position to a compressed position to reduce a volume of the interior, the container further comprising an elongate member coupled to a housing coupled to the reservoir, the elongate member comprising a fluid path from a distal extension through the housing to a proximal extension that communicates with the interior of the reservoir;
• coupling a drainage device to the distal extension;
• compressing the reservoir to the compressed position, a one-way valve in the distal extension preventing air within the interior from flowing back through the distal extension into the drainage device such that the air is evacuated out the proximal extension;
• releasing the reservoir such that reservoir is biased to return towards the expanded position, thereby generating a vacuum within the interior to draw fluid from the drainage device through the distal extension into the interior;
• and
• securing the proximal extension within a recess in the housing to prevent leakage from the interior via the proximal extension.
