ABSTRACT:
The present invention provides a medical needle assembly comprising in part a hub and a protector, each discrete from the other and having a lumen passing continuously therethrough. A hollow needle is enclosed within the continuous lumens and fixed to the base of the protector. A thin-walled weak point for separation of the hub and protector is provided near to the periphery of the area of hub and protector attachment. The hub and protector are attached using a solvent capable of dissolving the hub and protector materials, or an adhesive, the use of a plasticized vinyl chloride polymer paste resin being especially desirable. The present invention also provides a medical device in which the above medical needle assembly is incorporated in, and forms part of, a tubing line connected to a container holding blood.
