Abstract
Abstract A liquid sample collection apparatus which includes a collection receptacle with a plurality of joined but separable sample collection units. A liquid transmitting tube may be selectively positioned to discharge into a desired collection unit, without exposure to atmosphere and without sample cross-contamination. The tube has an outlet which is insertable through internal openings to the respective units. When a sample has been collected in one unit, the flow of fluid is stopped and the outlet end of the tube is withdrawn from the particular unit, but remains within the overall receptacle. The opening between the filled unit and its adjacent unit is then sealed, and the filled unit is separated from the receptacle. The whole system remains sealed to external contamination through successive sample collections and separations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A multiple liquid sample collection apparatus for collecting samples such as urine or the like, from a patient, comprising: a collection receptacle, a drainage tube for connection to receive a liquid discharged from a patient and having an outlet end positioned within said collection receptacle, said receptacle having a plurality of serially joined but separable flexible sample collecting compartments, each with at least one opening to adjacent compartments, the said openings being arranged so that the outlet end of said drainage tube is insertable through said openings in sequence to communicate with each of the compartments, and means for sealing predetermined ones of said openings subsequent to removal of the outlet end of said drainage tube and prior to separation of said separable sample collecting compartments.
Claim 2
Dependent Claim
126 words
A multiple liquid sample collection apparatus for collecting samples such as urine or the like, from a patient, comprising: a collection receptacle, a drainage tube for connection to receive a liquid discharged from a patient and having an outlet end positioned within said collection receptacle, said receptacle having a plurality of serially joined but separable flexible sample collecting compartments, each with at least one opening to adjacent compartments, the said openings being arranged so that the outlet end of said drainage tube is insertable through said openings in sequence to communicate with each of the compartments, and means for sealing predetermined ones of said openings subsequent to removal of the outlet end of said drainage tube and prior to separation of said separable sample collecting compartments.
