Abstract
A multiple liquid sample needle assembly is provided which utilizes a housing with a porous filter which is gas permeable and liquid impermeable for providing gas displacement venting for gas displaced by a liquid sample received in the housing. The invention incorporates a translucent or transparent housing for determining whether access to the liquid sample in question has been obtained. The filter of the assembly cooperates with the sequential application of a plurality of vacuum collection tubes to close off passage of air therethrough during the taking of the samples. In addition, the assembly is arranged to accommodate separate I.V. and negative pressure cannulas, or a single cannula with an I.V. and negative pressure point at opposite ends thereof.
