Abstract

Abstract A method for collecting fluids present at the body of a human being or animal. An enclosure is temporarily situated at a cavity of the body, this enclosure having within itself a hollow interior for receiving a body fluid while shielding the body from the interior of the enclosure and while a part of the enclosure is situated at the body cavity in proximity to a location where a body fluid which is to be collected is situated. The enclosure carries a transfer structure which creates between the interior of the enclosure and the above location of the body fluid conditions for only inward transfer of the body fluid from this latter location into the interior of the enclosure, the inward transfer conditions being maintained effective during at least part of the time while the enclosure remains at the body cavity. Thereafter, when the enclosure is separated from the body cavity, the desired body fluid will be situated in the interior of the enclosure.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 272 words
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, enclosing within the enclosure an agent which includes at least as a part thereof a nutrient for promoting the growth of certain microorgansims which may be present in the collected body fluid, creating between the interior of the enclosure and the body fluid conditions for transfer of the microorganism to the nutrient comprising a string which initially has a portion exposed at said part of said enclosure to receive said microorganism if it is present at said location, said string extending through a closed wall portion of said enclosure and being capable of being pulled though said closed wall portion at least to an extent sufficient for placing said portion of said string in engagement with the nutrient subsequent to introduction of the enclosure into the body cavity with said portion of said string situated at said location, and pulling said string through said closed wall portion to effect transfer of said microorganism, if it is present, into said enclosure, so that thereafter when the enclosure is separated from the body cavity, the microorganisms, if present in the body fluid, will be situated in the interior of the enclosure.
