摘要： A safety needle device and method of supplying fluid to a vascular access port is described. The device may include a base member, a handle member, and a compressible member positioned between the handle member and a compression plate. The compressible member is coupled to a proximal end of a needle. Following the delivery of fluid to a vascular access port, the needle is removed by moving the handle member away from the base member, which collapses the compressible member, flushing fluid into the vascular access port to substantially replace a volume of the needle.

摘要： A medical swab pouch is disclosed. The inexpensive elastic pouch contains disinfectant and is configured for protecting and swabbing a wide variety of luer systems to prevent and eliminate bacterial contamination. The pouch has a flattened configuration and can be elastically dilated, as by squeezing the pouch between the thumb and index finger and is readily carried in large numbers in nurse's pockets (in a manner similar to that for conventional alcohol swabs). The pouch covers and protects the luer valve at the discretion of the user and without transmission of torsion or longitudinal force which might loosen the luer valve or otherwise be transmitted to the vein.

摘要： In one embodiment, an automatic injector comprises a cartridge adapted to contain a charge of medicament, a seal structure disposed toward a forward end of the cartridge, a plunger normally disposed in a generally rearward end of the cartridge and movable through the cartridge toward a generally forward end thereof in response to an actuating procedure. The movable plunger rearwardly confines the medicament within the cartridge. A needle normally disposed in communication with the medicament container provides a passage in which the medicament is released into an individual's flesh in response to an actuating procedure projecting the needle into the flesh of the individual. The cartridge having an increased friction region so as to slow the motion of the plunger when the forward end of the needle travels through the seal in order to eliminate coring.

摘要： A safety needle device and positive flush mechanism for use with a vascular access port. In one embodiment, the combination needle assembly includes a needle, a body and a base, the body being collapsible to expunge fluid therefrom as the needle is withdrawn from a vascular access port. In another embodiment, the combination needle assembly includes a needle, a housing and a reservoir, the housing squeezing the reservoir to expunge fluid therefrom as the needle is withdrawn from the port. In another embodiment, the needle assembly includes a compression plate and balloon extension, the compression plate forcing fluid out of the balloon extension as the needle is withdrawn from the port. In all embodiments, the needle assembly is configured to provide a positive flush to overcome negative pressures in the vascular access port, while also providing a locking mechanism to prevent accidental needle sticks.

摘要： A syringe assembly including a needle cannula having a five-beveled point and a needle shield formed of a styrene block poly(ethylene/butylene) thermoplastic elastomer which significantly reduces needle penetration force and may reduce the cycle time for gas sterilization. The multi-beveled needle cannula point includes a primary bevel, a pair of tip bevels and a pair of middle bevels each intermediate the primary bevel and a respective tip bevel, wherein the angles of rotation of the primary bevel and the intermediate bevels are substantially equal resulting in reduced heights of intercepts between the bevels, therby reducing needle penetration force. The needle shield maintains the sharpness of the needle cannula during application, sterilization and removal of the shield and it is believed that the needle shield will also reduce the cycle time of gas sterilization as compared to rubber needle shields and vulcanizate thermoplastic elastomers.
摘要翻译：一种注射器组件，其包括具有五斜面的针插管和由苯乙烯嵌段聚（乙烯/丁烯）热塑性弹性体形成的针护罩，其显着降低针穿刺力并且可减少气体灭菌的循环时间。所述多角针插管点包括主斜面，一对尖端斜面和一对中间斜面，每个中间斜面均在所述主斜面和相应的尖端斜面之间，其中所述主斜面和所述中间斜面的旋转角度基本相等导致斜面之间的截距的高度减小，从而减少针的穿透力。针护罩在施加，消毒和除去护罩期间保持针管的清晰度，并且相信与橡胶针护罩和硫化橡胶热塑性弹性体相比，针罩还将减少气体灭菌的循环时间。

摘要： A pre-slit injection site (34) includes a housing (40) with a flow path therethrough. A first end (42) of the housing (40) carries a pre-slit septum (52). One form of a blunt cannula (98), usable with the injection site (34), carries a locking member (100). When the pre-slit injection site (34) slidably receives the blunt cannula (98), the locking member (100) latches to the injection site (34) and creates a mechanically coupled unit. Another form of the cannula (280) includes a tube having a tapered distal end region (298) and having elongate discharge slots (294) for reducing contact surface area and for directing the flow laterally out of the cannula. The cannula may also include a rounded lead post (330), an annular barb (394), and axially oriented grooves (268).

摘要： In a fluid sampling system, a pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. One form of a blunt cannula, usable with the injection site, carries a locking member. When the pre-slit injection site slidably receives the blunt cannula, the locking member latches to the injection site and creates a mechanically coupled unit. Another form of the cannula includes an elongated member having a tapered distal end region and a substantially cylindrical sheath surrounding the elongated member to protect it from inadvertent touch contamination. The sheath may include means defining at least two slots opposite one another at its distal end and the sheath may be outwardly tapered.
