Needle safety device for an intravenous catheter apparatus

摘要

A needle safety device 40 for an intravenous catheter apparatus that includes a base 42 capable of receiving a needle 20 between opposing jaws 48 attached to the base and capable of being influenced by the needle 20. The jaws have a link 49 connecting the jaws arranged a distance from the base 42. The jaws may move between an expanded position in which they interact with an obstruction within a wing housing of the intravenous catheter apparatus. The jaws 48 permit relative movement of the needle 20 with the base when expanded, close around a needle tip as it passes the jaws, and prevent relative movement of the needle 20 with the base when the jaws are collapsed. The needle 20 of the intravenous catheter apparatus may then be safely disposed with the needle tip within the needle safety device.
