摘要： 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.

摘要： The present invention is an injection port assembly for subcutaneous delivery of medication. A single molded body has a soft cannula extending downward from a generally flat bottom surface and a self-sealing septum mounted at the center of a top surface which is generally of a concave shape sloping downward towards its outer perimeter at which point the single body is very thin. The single body also has a tubular extension which is directed outward parallel to the skin's surface. A metal needle which penetrates through the septum and through the lumen of the soft cannula is used for inserting the cannula through the skin. Once the soft cannula is placed subcutaneously, the needle is removed and an adhesive tape is placed over the single body and onto the skin beyond the body's outer perimeter. By having a distal section of the needle which is smaller in diameter as compared to most of the needle's length, and by having the soft cannula fit tightly onto the needle, most of the cannula's length will be in tension during insertion thereby preventing an accordion-like compressional failure of the cannula. A quick-release connector on the proximal end of the tubular extension or mounted directly on the injection port assembly allows the tubing connecting the injection port assembly to a portable medication pump to be disconnected when the patient showers or performs some similar activity.
