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

1. 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.

2. The device of claim 1, further comprising

(a) said gelation containing sheet material being in the form of a plurality of pieces with one piece covering one of said openings.

3. The device of claim 1 comprising

(a) said sheet material containing said gelation material being in the form of an elongated package containing said gelation material;

and

(b) said elongated package being positioned in an aqueous liquid containing chamber.

4. The device of claim 1, further comprising

(a) said elongated container is circular in cross-section.

5. The device of claim 1, further comprising

(a) said elongated container is square in cross-section.

6. A suction cannister for receiving body fluids from an operation site, comprising

(a) a cannister having circular side walls;

(b) a bottom wall;

(c) a top opening;

(d) said circular side walls extending from said bottom wall to said top opening to define a body fluid collection chamber;

(e) a closure for said top opening;

(f) an access opening in said closure;

(g) a device for evenly distributing gelling material simultaneously over the entire extent of said cannister chamber, said device including

(1) an elongated container having a first end and a second end;

(2) walls extending from said first end to said second end;

(3) a plurality of openings in said walls, said openings extending from a point adjacent said first end to a point adjacent said second end;

(4) 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 dissolvable in aqueous containing liquids introduced into said suction cannister chamber;

(5) a gelation material in said device container, said gelation material responsive to exposure to aqueous containing liquids for the gelation thereof; and

(h) said elongated distributing device fixed in said suction cannister chamber with said first end adjacent said bottom wall and said second end adjacent said top opening closure.

7. The device of claim 6, further comprising

(a) said elongated container is circular in cross-section.

8. The device of claim 6, further comprising

(a) said elongated container is square in cross-section.

9. The device of claim 6, further comprising

(a) said gelation containing sheet material being in the form of a plurality of pieces with one piece covering each of said openings.

10. The device of claim 6 further comprising

(a) said sheet material containing said gelation material being in the form of said elongated container containing said gelation material.

11. 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) said walls comprised of a gelation containing sheet material, said sheet material comprised of a material immediately dissolvable sequentially in stages in aqueous containing liquids as it comes into contact with said aqueous containing liquids;

(d) a gelation material in said chamber, said gelation material responsive to exposure to aqueous containing liquids for the immediate gelation thereof;

(e) a flat backing for said container;

(f) one side of said container adhered to said flat backing; and

(g) adhesive adhered to the side of said flat backing opposite said container for adhering said flat backing with the said elongated container attached vertically to the inside wall of an aqueous liquid collection device.

12. The device of claim 11, further comprising

(a) said elongated container is circular in cross-section.

13. The device of claim 11, further comprising

(a) said elongated container is square in cross-section.
