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.
摘要翻译：为紧凑型小孔医疗针回缩安全装置的设计提供基础的方法和装置的公开，其中致动器从细长的针头护套体移开，以启动使用后安全地容纳医用针的针回缩循环。这样的致动器防止无意的动作，例如按下致动器，这可能导致不恰当的针回缩。公开了本发明的四个实施例。在一个实施例中，针回缩能量被储存，因为医疗针被延伸使用并且被消耗以将针收回到安全的容纳物中。其他实施例包括动力辅助机构，其在针回缩的初始阶段期间存储能量，以用于在针回缩完成阶段期间增强和辅助针缩回。在一些实施例中，通过一对刚性的，细长的铰接互连的臂来促进缩回，所述臂进一步铰接地联接到针毂组件和装置主体，使得一个臂旋转大约180°以将针缩回距离大于旋转的臂的长度以便于回缩致动。一个动力辅助机构包括模制成一个臂的可变形构件的部件。为了实现低成本制造，操作装置可以由少至两个注塑部件制成。易于观察的血液闪光室允许早期检测针入血管。

摘要： A retractable and extendable medical needle protective shield which provides opportunity for accessing and reaccessing a medical needle and associated sharpened needle tip and recovering the needle and tip for safety between accesses. The shield includes a needle guide which assures the needle tip is untouched by any part of the shield as the shield is displaced to cover and uncover the needle. A releasible latch is provided to guard against inadvertent removal of the protective shield between accesses. An unreleasible latch is also provided to secure the shield relative to the latch preparatory to final disposal. In combination with the protective shield, a plurality of adapters are disclosed which provide examples of passively operated, protected access to membrane pierceable fluid sources such as a “Y” connection site of an IV set line, a drug vial, a vacuum sample tube, an umbilical cord holder and a hypodermic site.

摘要： A practical, low cost safety device for phlebotomy. Preparation for operation of the device involves elongating an otherwise shortened-for-transport apparatus to extend a medical assembly and needle from a housing for use in a medical procedure. The act of elongating energizes an energy storing component and cocks a releasable latch. The energy storing component is preferably a vacuum drawing plunger and tube combination. When the medical procedure is complete, distortion of a portion of the housing causes powered retraction of the needle. After retraction, the needle is fully contained, permitting the device to be laid aside without fear of an inadvertent needle stick. The housing comprises a proximal barrel and a distal needle containment section. The barrel comprises a sampling tube stopper piercing cannula. The distal section is disposed in-line, but off-axis from the barrel and comprises an enclosed conduit which communicates with the cannula and with a pathway to the medical needle through the medical needle assembly. Construction of the device requires only three injection molded parts, the housing, a needle hub and a needle cover. Further, as the needle is retracted, communication from the conduit is severed and the pathway to the needle is closed to reduce likelihood of blood spatter. The conduit may be used as a blood flash visualization chamber.

摘要： Method and apparatus associated with safe retraction of medical needles after use. Embodiments are disclosed for self-retracting needle systems for both blood draw, syringe and catheter insertion systems. Invention manufacture requires only a minimal number and complexity of parts such that a 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 each of the disclosed the embodiments is also disclosed. One blood draw embodiment can be made with as few as three molded parts. Energy-storing, needle-retracting mechanisms comprise elastic tubing and vacuum generating piston parts. In an elastic tubing embodiment, selective, constrictive control of stretched tubing volumes effectively inhibits regurgitant flow from the needle. In all embodiments, needle retraction is a single handed operation permitting a technician's other hand to be used in wound care. A combination of parts, comprising the apparatus housing and a needle cover, are used as a transport container which protects a medical needle from inadvertent contamination with requiring special packaging, thereby, further reducing apparatus costs.

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： Method and apparatus associated with safe retraction of medical needles after use. Embodiments are disclosed for combinations comprising medical syringes and self-retracting needle systems. An energy-storing, needle-retracting mechanism comprises an elastic tubing which also is taught perform a plurality of functions comprising the storing of force by which a medical needle is retracted, slidable seals, normally dosed valves and dynamic volume control by which fluid regurgitation upon needle retraction is voided. Selective, constrictive control of the internal volume of the tubing when stretched effectively inhibits regurgitant flow from the needle as the tubing relaxes while retracting the needle. In all embodiments, needle retraction is initiated by forces applied in a direction transverse to the long axis of the needle using but a single hand. The syringe may be used in a plurality of modes such as a standard syringe or as a pre-filled syringe. Methods for making and assembling the combination are also disclosed. Invention manufacture requires only a minimal number and complexity of parts such that a projected manufacturing cost is potentially low enough to permit the apparatus to be cost competitive with contemporary combinations of hypodermic syringes and non-self retracting needle systems.
