摘要： Provided is a non-coring needle for venous access implantatable port comprising a puncturing assembly comprising two wings having a central sleeve, an L-shaped needle coupled to the sleeve, the needle including an annular groove on its horizontal portion, and a plastic tubing coupled to the sleeve; and a syringe barrel comprising an internal chamber having a forward opening, and an elongate slot formed on the syringe barrel and being in communication with the chamber. The groove is located at a first dent of the slot when the needle is concealed in the chamber in a non-use position, the groove is located at a forward second dent of the slot when the needle is fully extended from the opening for use, and the groove is permanently locked at a rear triangular recess of the slot when the needle is fully retracted into the chamber respectively.

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assembly includes a needle, a body and a base, the body being collapsible to expunge fluid therefrom as the needle is withdrawn from a vascular access port.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a needle, a housing and a reservoir, the housing squeezing the reservoir to expunge fluid therefrom as the needle is withdrawn from the port.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plate and balloon extension, the compression plate forcing fluid out of the balloon extension as the needle is withdrawn from the port.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.

摘要： A body lumen access system comprises a distal access cannula and a proximal access cannula. The distal access cannula is attached to or within the body lumen and the proximal access cannula is attached to an implantable port or is transcutaneously positioned and attached to a luer or other external connector. The distal and proximal access cannulas are usually implanted separately, cut to length, and attached at a subcutaneous junction location. Preferably, the proximal access cannula has a larger lumen diameter than that of the distal access cannula in order to reduce flow resistance within the cannula system. In some cases the distal and proximal access cannulas may be formed integrally.

摘要： Disclosed is a connector for introducing medication into a patient in a safe, convenient way. It comprises a pair of plastic tubular members adapted to be manually pushed together to engage in a male-female relationship, and a locking mechanism that detachably secures the members together. The male member has a sealed entry port at its end, and the female member safely houses within it a needle which centrally pierces the seal of the port upon engagement of the members. Preferably, the locking mechanism provides a "click" sound when it locks the members together.

摘要： A hypodermic needle featuring a multi-beveled point geometry is disclosed. In one embodiment, the multi-beveled point features a primary bevel, a pair of tip bevels, and a pair of middle bevels each intermediate the primary bevel and a respective one of the tip bevels. The primary and middle bevels are provided at angles of inclination, measured between the central axis and a reference plane that are substantially identical. The tip bevels are formed at an angle of inclination respective to the central axis which is not equal to the angle of inclination at which the primary and middle bevels are formed. The resulting five-beveled point geometry contributes to a more continuous bevel face free of abrupt intercepts or transitions between the respective bevel faces, lessening the penetration force required to urge the needle point through skin, flesh, or other material.
摘要翻译：公开了一种具有多斜角几何形状的皮下注射针。在一个实施例中，多倾斜点具有主斜面，一对尖端斜面和一对中间斜面，每个中间斜面均位于主斜面和相应的一个尖端斜面之间。主斜面和中间斜面以倾斜角度设置，在中心轴线和基本相同的参考平面之间测量。尖端斜面以不同于形成初级和中间斜面的倾斜角度的中心轴线的倾斜角形成。所产生的五角点几何有助于更连续的斜面在各个斜面之间没有突然的截距或过渡，从而减少了将针尖推向皮肤，肉体或其他材料所需的穿透力。
