ABSTRACT:
A hypodermic needle system that comprises a hub engaging close-fittingly over the end portion of the cylinder of a syringe and coupling means that consists of flexible legs capable of gripping the proximal end of the needle. In another embodiment, the apparatus also comprises a connecting element that is fixedly attached to the needle and is releasably mounted inside the hub, and the coupling means consists of flexible legs capable of gripping the connecting element. As a result of these configurations, the number of components in the hypodermic syringes constructed according to this invention is limited and the products are relatively inexpensive to manufacture.
