1. In a method for collecting fluids from the body of a human being or animal, the steps of positionally arranging an enclosure in juxtaposition to a cavity of the body which at least at times contains body fluid in such manner that when the body fluid is present in the cavity the enclosure is in contact with the body fluid, said enclosure having within itself a hollow interior for receiving the body fluid while shielding the body from the interior of the enclosure, creating between the interior of the enclosure and the body fluid conditions for only inward transfer of the body fluid into the interior of said enclosure, the inward transfer of the body fluid into the enclosure commencing solely as a result of the contact with the body fluid, so that the collection commences automatically without external actuation, and maintaining said inward transfer conditions effective at least part of the time while the enclosure remains in contact with the body fluid, so that thereafter when the enclosure is separated from the body cavity, the desired body fluid will be situated in the interior of the enclosure.
