Abstract

Some embodiments of the invention provide a needle comprising a shaft with a sharp open end and a hub with a blunt open end, housed in a barrel with an open anterior end and an open posterior end. The hub of the needle can move forward inside the barrel, for extending the sharp open end of the shaft of the needle for insertion into a vessel, e.g. a blood vessel, a catheter, or a capped tube. After use, the hub can move backwards inside the barrel for retracting the shaft of the needle into the barrel. The blunt open end of the needle can be fluidly connected to the inlet opening of a measurement apparatus, so that the blood can flow directly from a vessel, into the measurement apparatus, without the use of a syringe. The hollow needle assembly can also be used with a traditional syringe, as an alternative to traditional needles, in order to minimize the risk of needle-stick injury.
