Abstract

An absorbent body for collecting blood, faeces and urine contains a water-soluble copper salt which impedes bacterial growth, prevents the breaking-down of urea into ammonia and complex-binds ammonia so as to prevent the occurrence of unpleasant odor. Preferably copper acetate is used, in which even the acetate ion has germicidal effect.

Claims

1. An odor-inhibiting and germicidal absorbent body for collecting urine or feces, said body comprising cellulose fibers or wadding, wherein the fibers or wadding at one surface of said body which, in use, first comes into contact with urine or feces are impregnated with an odor-inhibiting and germicidal solution consisting of an aqueous solution of a water-soluble copper salt selected from the group consisting of copper formate, copper oxalate, copper tartrate, copper citrate, copper lactate, copper sulfate, copper chloride, copper acetate and copper borate, said copper salt being concentrated in said fibers or wadding at said one surface such that there is present at least 150 μ

g copper per milliliter of the liquid volume which said absorbent body is dimensioned to absorb.

2. The odor-inhibiting and germicidal absorbent body of claim 1 wherein said copper salt is copper acetate present in an amount ranging from 1.2 to 2.5 g of copper acetate, calculated as dry substance, per m² of said surface which first comes into contact with urine or feces.
