Abstract
An assembly for connecting needles and catheters in I.V. applications, chemical analysis, etc., includes a leak proof, sterile, self-sealing septum from which the needle is inserted. When the needle is retracted from the septum, the septum will reseal and thus maintain a leak-proof, sterile seal. The assembly is therefore reuseable, and this represents a considerable cost saving for patients who require continuous therapy such as with diabetics, cancer patients, and the like. The assembly includes a distal end having an outlet bore through which a catheter is inserted. The proximal end of the assembly is connected to an external adaptor to which is attached a needle. The septum is positioned between the distal end and the proximal end to provide a self-sealing seal between the needle and the catheter. This external adaptor with needle may be part of a syringe or shaped to accommodate any standard connector such as a luer lock. Depending on the application, the fittings may be manufactured from a wide range of materials including plastics and metal. For example, as an inexpensive disposable item, the fitting would preferably be manufactured from molded plastic.
