摘要： Disclosure of methods and apparatus providing bases for design of compact small bore medical needle retraction safety devices wherein actuators are displaced away from slender needle sheathing bodies to initiate a needle retraction cycle for safely containing a medical needle after use. Such actuation guards against inadvertent acts, such as depression of an actuator, which may result in untimely needle retraction. Four embodiments of the instant invention are disclosed. In one embodiment, needle retracting energy is stored as a medical needle is extended for use and is expended to retract the needle into safe containment. Other embodiments comprise power assist mechanisms which store energy during an initial phase of needle retraction to be used to enhance and assist needle retraction during a needle retraction completing phase. In some embodiments, retraction is facilitated by a pair of rigid, elongated, hingedly interconnected arms which are further hingedly coupled to a needle hub assembly and to a device body such that one arm is rotated approximately 180° to retract the needle a distance greater than the length of the so rotated arm to facilitate retraction actuation. One power assist mechanism comprises a part molded as a distortable member of one of the arms. To realize low cost manufacture, the operating device can be made from as few as two injection molded parts. A readily viewable, blood flash chamber permits early detection of needle entry into a blood vessel.

摘要： Method and apparatus associated with safe retraction of used medical needles. Embodiments are disclosed for self-retracting needle systems for medical syringe, blood withdrawal and catheter insertion systems. Invention manufacture requires only a small number and complexity of parts such that projected manufacturing cost is potentially low enough to permit the apparatus to be cost competitive with contemporary non-self-retracting needle systems. Methods for making and assembling blood withdrawal, syringe and catheter embodiments are disclosed. Energy storing retracting mechanisms comprise elastic tubing and vacuum generating piston parts. Triggerable release mechanisms generally comprise two parts or two frangible segments of one part disposed about a medical needle. Each release mechanism involves one part or segment which is securely affixed to the needle and one part or segment which is free to slide and rotate about the needle. The medical syringe is a self-retracting needle apparatus which may be releasibly affixed to a standard medical syringe having a luer lock fitting. In all embodiments, needle retraction is a single handed operation permitting a technicians other hand to be used in wound care. Use of frangible parts permits the apparatus housing to provide a sterile barrier and be used as a transport container to reduce costs.
摘要翻译：与使用过的医用针头的安全回缩有关的方法和装置。公开了用于医疗注射器，抽血和导管插入系统的自动回缩针系统的实施例。发明制造仅需要少量和复杂的部件，使得预计的制造成本潜在地足够低以允许该装置与当代非自动回缩针系统具有成本竞争力。公开了制备和组装取血，注射器和导管实施例的方法。蓄能回缩机构包括弹性管和真空产生活塞部件。可触发释放机构通常包括设置在医疗针周围的一部分的两个部分或两个易碎部分。每个释放机构包括一个部分或部分，其牢固地固定到针上，一个部分或部分可自由地围绕针滑动和旋转。医疗注射器是自回缩针装置，其可以可释放地固定到具有路厄锁定配件的标准医疗注射器。在所有实施例中，针回缩是单手操作，允许技术人员将其他手用于伤口护理。使用脆弱部件允许设备外壳提供无菌屏障，并用作运输容器以降低成本。

摘要： Medical needle shield apparatus for covering a needle after use. The medical needle shield apparatus is for use with a needle having proximal and distal ends, wherein the shield is slidably movable along the needle from a proximal position where the distal end of the needle is exposed, to a distal position where the shield covers the distal end of the needle. The shield comprises one or more clips having two or more apertures through which the needle passes, wherein the apertures have surfaces. A clip positioning member, in communication with at least one of the clips, positions the aperture surfaces of at least one of the clips when a portion of the clip positioning member in contact with the needle is advanced past the distal end of the needle such that at least a portion of the aperture surfaces of the two or more apertures binds to the needle with opposing binding forces so as to secure the shield to the needle.
