A container has an upper fluid receiving portion and a lower fluid discharge portion which is closed off at its bottom by a closure. In carrying out the method of the invention, a blood sampling from the umbilical cord of a newly born infant is taken by first clamping off a section of the cord. The clamped section is then separated from the main portion of the cord and deposited into the container. One of the clamps is then removed to permit the blood in the cord section to drain into the container. The drained blood is then transferred to a second container, which may comprise a test tube or syringe, through the fluid discharge portion of the container, this being achieved by either causing a needle attached to the container and sealed with a needle cover to penetrate the needle cover as well as the test tube cover, penetrating the closure with a needle if it be a diaphragm or the like or opening a valve at such closure by a mechanical actuation with the nose of a syringe. The needles employed are protected by shielding hoods to prevent accidental needle sticking.

[ I claim:] [1.] A system for use in receiving a sample of human tissue containing body fluid, separating said fluid from said tissue and dispensing said fluid comprising:a first container, said first container being at ambient atmospheric pressure,said first container having an upper receiving portion with an open top for receiving said tissue sample and including means for separating the fluid from the tissue sample in said receiving portion solely by gravity flow and without any filtering of the fluid,said first container further having a lower fluid discharge portion in fluid communication with said upper receiving portion, there being no liquid filter between said lower fluid discharge portion and said upper receiving portion for filtering out particles from said fluid,a second container connected to said first container, anda normally closed off port connected to the lower discharge portion and located between the lower discharge portion and said second container for preventing the separated fluid from entering said second container, said normally closed off port initially sealing off flow of fluid from said first container to said second container and being adapted to be opened in response to a mechanical actuation to release said fluid to said second container,said second container receiving and retaining said fluid for later analysis,whereby the likelihood of contact between said fluid and the hands and fingers of the user of said system is minimized.
