ABSTRACT:
A blood tube communicating with a blood bag includes means for parting the blood tube, and exposing an internally mounted needle carried by and communicating with the blood tube for penetrating a closure of a sample tube. In accordance with this invention, the above is accomplished by means of an integral plastic member which is positioned to sealingly enclose an interrupted portion of the flexible blood tube and the needle. The plastic member includes a thin-walled, frangible portion positioned to permit separation of the plastic member into two pieces by breaking of the frangible portion to expose the needle for use, and to permit the blood tube to be separated. Manually operated means are also provided for shutting off flow through the blood tube at a point on the opposite side of the plastic member from the blood bag.
