摘要： A skin puncture device for use as an intravenous catheter or blood collecting needle set is provided with a mechanism for protection against needle injury and access to fluid passageway during insertion. The assembly includes a flexible extension tube connected to the proximal end of the needle housing for use in difficult insertion sites. The extension tube provides access for fluid injection so that the passageway and needle can be filled with fluid prior to needle/catheter insertion, allowing diffusion of blood to provide evidence of successful venipuncture and allowing the infusion of small amounts of fluid into the vein to facilitate catheter advancement. The locking mechanism consists of two apertures in the needle housing and two pairs of needle guard locking tabs which selectively engage when the needle guard is pushed forward to its fully extended position upon completion of insertion or blood drawing, encapsulating the length of the needle.

摘要： The disclosed invention provides a telescoping tip protector for reducing the risk of needle sticks in used catheter introducers. The pair of telescoping members are adapted such that they telescope from a housing which is gripped by the user with one of the telescoping members locking in a position extending from the housing and the second member locks in a position extending from the first member. The second member carries thereon a tip protecting portion which surrounds the cannula tip and prevents the inadvertent jabbing, piercing or sticking of the needle into a person after the use of the introducer and engagement of the protector.

摘要： A solid blunt and a needle assembly having a solid blunt. The solid blunt helps to prevent accidental needle sticks. In one exemplary embodiment, a solid blunt has an outer dimension (e.g. outer diameter) which is nearly equal to an inner dimension (e.g. inner diameter) of a cannula of a needle which is configured to contain the solid blunt. In one example, the solid blunt substantially blocks fluid flow in a first circumferential portion of an inner diameter of the cannula and allows fluid flow in a second circumferential portion of the inner diameter. The solid blunt is typically capable of longitudinal movement through the cannula and is prevented from moving substantially in a direction perpendicular to the longitudinal movement. A needle assembly, in another exemplary embodiment, includes a solid blunt, a cannula and a clip which couples slidably the solid blunt to a frame which is coupled to the cannula. The present invention may be used with medical devices including needles, introducers and catheters and other devices as well.

摘要： A method of fabricating a printed circuit board is disclosed. The method comprises forming a metal substrate having a through-hole pattern. The metal substrate is coated with a dielectric powder having a suitable flow length value to form a dielectric coat on the substrate having a sufficient through-hole edge coverage. The dielectric coated substrate is then treated with a second powder to form a satisfactory topcoat thereon. Electrical circuitry is then formed on the topcoat in conjunction with the through hole pattern.
