Abstract: A disposable blood drawing device has an evacuated container and holder therefor as well as a dual needle assembly which is connectable to the holder. The assembly has an elongated housing with opposite end openings in which hypodermic and tap needles are respectively mounted and internally interconnected by a resilient tube that is compressable against one of the opposite walls of the housing by means of a push button which is manipulated exterially to compress and thus limit the flow through the resilient tube. The push button has a lateral stop element that will pass through an opening for receiving the push button during the assembly of the assembly but which engages the internal surface of one wall of the housing to prevent withdrawal of the button. The mounting for the tap needle carries an adaptor for connecting the device with the holder.

Abstract: A convoluted cord retainer for a macrame device has coils that are centered on an arcuate axis so that the coils touch on one side of the arrangement and are spaced apart on the other side of the arrangement. One device embodying the convoluted retainer has a support adapted with a hook for suspending the arrangement from a household door and the retainer and a holder for the macrame cords are slidably supported on an elongated rod that serves as the support component of the device. Another device utilizing the convoluted retainer has a rigid frame with spaced sides that straddle the users thigh during use, the device having a flexible connection between the sides which serves in orienting the frame in the users lap. The device here has a clamp at one end for holding the macrame cords and the convoluted retainer is located at the other end to receive and clasp the loose cord ends.
