Abstract
Abstract A device is provided for deliberately distributing simultaneously over the entire vertical and/or longitudinal extend of a body of aqueous containing liquid a gelation agent for the rapid containment of contaminated aqueous liquids. The device is an elongated rigid or semi-rigid body for containing an envelope or package of material immediately dissolvable in the aqueous liquids, and which contains the gelling agent prior to liquid exposure. The device includes means for exposure of its content to the liquid, once the device is positioned in or is surrounded by the liquid. The invention contemplates a conventional suction canister having the device positioned therein for receiving contaminated body fluids.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
139 words
A device for evenly distributing gelling material simultaneously over the entire extent of a container of aqueous containing liquid, comprising (a) an elongated container having a first end and a second end; (b) walls extending from said first end to said second end and defining a chamber; (c) a plurality of openings in said walls, said openings extending from a point adjacent said first end to a point adjacent said second end; (d) a sheet material for containing a gelation material, said sheet material closing each of said plurality of openings, said sheet material comprised of a material immediately dissolvable sequentially in stages in aqueous containing liquids as it comes in contact with the aqueous containing liquids: (e) a gelation material in said chamber, said gelation material responsive to exposure to aqueous containing liquids for the immediate gelation thereof.
