The input (38) is entirely separated from an external medium by a film which is made of a liquid-tight and gas-permeable hydrophobic material and whose face opposite to the input (38) is directly accessible for the body fluids. The liquid-tight and gas-permeable hydrophobic material (32) contains a laminated non-woven matter and a polypropylene membrane. The filter is suitable for pockets collecting body fluids.
