Abstract
A biological fluid collection container comprising a cup member, a lid assembly removably mounted to the cup member comprising a housing with a downwardly extending cylindrical skirt, a luer lock with a throughgoing bore extending from one side of the lid housing. A hollow tube extends from the other side of the lid housing adjacent the luer lock and is axially aligned with the throughgoing bore of the luer lock. The hollow tube is provided with a plurality of throughgoing holes leading into its lumen along its surface to provide for a sampling along various liquid level layers of the biological fluid specimen collected in the cup member so that when the biological fluid specimen is removed from the cup member a representative sampling is obtained.
Claims21
An apparatus comprising:
- a plurality of specimen collection containers defining a fluid flow path, intermediate ones of the containers along the fluid flow path each having an inlet and an outlet, and at least one container having chromatographic bed material for capturing particulate matter and cells.
An apparatus comprising:
- a first housing having a first inlet and a first outlet, said first housing defining a first portion of a fluid flow path and having a filter membrane disposed between the first inlet and the first outlet for capturing cells in the fluid flow path;
- and
- a second housing having a second inlet and a second outlet, said second housing defining a second portion of the fluid flow path and having a chromatography element disposed between the second inlet and the second outlet.
An apparatus comprising:
- a first housing having a first inlet and a first outlet, said first housing also having a filter membrane disposed between the first inlet and the first outlet for capturing cells;
- a second housing having a second inlet and a second outlet, said second housing having chromatographic bed material disposed between the second inlet and the second outlet;
- and
- a specimen container having a lid suitable for fluid communication with the first inlet or the second inlet, said lid having a tube extending into the specimen container, said tube having at least two perforations at different longitudinal points along its length;
- wherein the lid is in direct fluid communication with the first inlet or the second inlet, and the first outlet is in direct fluid communication with the second inlet or the second outlet is in direct fluid communication with the first inlet, respectively.
