Abstract
Disclosed is a needle assembly to be used with a pen-type injector and a percutaneously placed catheter device for intravenous infusion or a subcutaneously inserted cannula that is part of an injection set. Unlike all prior art needle assemblies which have a sharp point at the needle's distal end, the needle assembly described herein has a blunt tip so as to avoid any inadvertent needle sticks. This invention envisions using such a blunt tipped needle assembly connected to a pen-type injector and used with an injection set that has a cannula placed in the subcutaneous tissue. This invention also envisions using such a blunt tipped needle assembly with a pen-type injector for intravenous injections of medication through any intravenous catheter that has a septum through which the blunt needle of the pen-type injector can be placed.
