摘要： Needle capture mechanisms and arrangements are provided. One such arrangement includes a needle defining a longitudinal needle axis having a sharp distal tip, a shank portion, and a needle feature defining at least one localized area along the shank of increased outer diameter; a needle shield; and a biasing member adapted to exert a generally downward biasing force upon the needle. Another such arrangement includes a needle defining a longitudinal needle axis having a sharp distal tip, a shank portion, and a needle feature defining at least one localized area along the shank of increased outer diameter; a needle shield, the needle shield comprising a pocket formed therein having an inclined surface; a split collet disposed within the pocket, the split collet having a variable inner bore; and a biasing element disposed within the pocket for biasing the split collet toward the inclined surface of the pocket.

摘要： An eccentric rotary high pressure seal is disclosed herein. This seal includes a valve body and a spring located in a housing. The spring biases the valve body to rotate. The valve body defines a longitudinally extending passage having dimensions sufficient to allow an introducer needle to pass there through. This passage is offset from the axis of the valve body. The valve body is located in a housing that will allow the valve body to rotate therein. The housing defines two longitudinally aligned openings that are offset from the axis of the housing. These two longitudinally aligned openings are oriented such that the passage in the valve body can be aligned with the openings located in the housing. In this manner, an introducer needle can extend into the housing and hold the valve body against the bias of the spring. Once the introducer needle is removed from the housing, the valve body is no longer held in place against the force of the spring. Therefore, the spring causes the valve body to rotate within the housing so that the passage in the valve body is not aligned with the two longitudinally aligned openings formed in the housing. This prevents fluid flow through the housing past the valve body once the introducer needle is removed therefrom.
摘要翻译： 本文公开了一种偏心旋转高压密封件。 该密封件包括阀体和位于壳体中的弹簧。 弹簧偏压阀体旋转。 阀体限定了具有足以允许导引针穿过其中的尺寸的纵向延伸的通道。 该通道偏离阀体的轴线。 阀体位于允许阀体在其中旋转的壳体中。 壳体限定两个纵向对齐的开口，其偏离壳体的轴线。 这两个纵向对准的开口被定向成使得阀体中的通道可以与位于壳体中的开口对准。 以这种方式，引导器针可以延伸到壳体中并抵抗弹簧的偏压保持阀体。 一旦引导器针从壳体上取下，阀体就不会因弹簧的力被固定到位。 因此，弹簧使得阀体在壳体内旋转，使得阀体中的通道不与形成在壳体中的两个纵向排列的开口对准。 一旦引导器针从其移除，这就防止流体通过壳体流过阀体。

摘要： A needle assembly is provided with a needle securely mounted to a needle hub. A shield assembly includes a plurality of telescoped tubes concentrically surrounding the needle. One of the telescoped tubes is securely connected to the needle hub. The other tubes in the assembly may be slid away from the needle hub. The tubes have combined lengths to enable complete shielding of the needle when the tubes are telescopingly extended. The distal-most tube, when the tubes are telescopingly extended, includes a tip guard which resiliently moves over the distal tip of the needle as the shield assembly is fully extended. The distal-most tube, when the tubes are telescopingly extended, of the shield assembly frictionally engages a catheter adapter to prevent withdrawal of the needle from the shield assembly until the tubes are fully telescopingly extended. As full shielding of the needle is reached, the shielded needle is separated from the catheter adapter.

摘要： The catheter includes a catheter hub at its proximal end having a radially extending wing. The needle is connected at its proximal end to a needle hub. The needle may have at least one notch therein. The needle hub defines a radially extending fin thereon. When the introducer needle is inserted through the catheter such that the distal tip of the needle extends beyond the distal tip of the catheter, the fin on the needle hub extends beyond the distal end of the wing on the catheter hub. This arrangement allows the distal tip of the needle to be retracted into the catheter with a simple proximal motion by the healthcare worker.

摘要： A needle point guard assembly includes inner and outer housings disposed in nested relationship to one another to permit relative rotation therebetween. The proximal end walls of the inner and outer housings have apertures each of which is dimensioned to slidably receive a needle. The apertures are disposed in the housings such that they are registered in one rotational orientation of the housings relative to one another to define a first opening that allows a needle to pass therethrough. The needle point guard assembly further includes a spring for rotatably driving the housings relative to one another and a trigger for selectively holding the inner housing with respect to the outer housing in a rotational orientation where the apertures define the first opening. The trigger moves out of interfering relationship between the inner housing and the outer housing when the sharp distal tip of the needle is withdrawn into the needle point guard assembly. In this condition, the spring will rotatably drive the housings into orientations where the apertures will not be substantially aligned so that the overlapping area is smaller than the first opening. The edges of the apertures will thus bind against the needle and prevent further movement of the needle point guard assembly either proximally or distally along the needle.
摘要翻译： 针头保护组件包括以彼此嵌套的关系设置以允许它们之间相对旋转的内壳体和外壳体。 内壳体和外壳体的近端壁具有孔，每个孔的尺寸可滑动地容纳针。 孔被布置在壳体中，使得它们相对于彼此以壳体的一个旋转取向配准，以限定允许针穿过其中的第一开口。 针尖保护组件还包括用于相对于彼此可旋转地驱动壳体的弹簧和用于以旋转定向相对于外壳选择性地保持内壳体的触发器，其中孔限定第一开口。 当针尖的尖端远离针头保护组件时，触发器移出内壳和外壳之间的干涉关系。 在这种情况下，弹簧将可旋转地驱动壳体的方向，其中孔不会基本对准，使得重叠区域小于第一开口。 因此，孔的边缘将与针结合并防止针尖护罩组件沿着针的近端或远端进一步运动。

摘要： A needle point guard having a movable collet to lock the needle in place in the shielded position is provided. The needle point guard of this invention includes a housing, a collet, a rotary ram, a threaded cam fixed to the rotary ram, a spring disposed between the rotary ram and the housing and a trigger catch to hold the threaded cam in place against the force of the spring. The spring is wound when the needle is in the unshielded position. When the needle is withdrawn into the needle point guard, the trigger catch pivots to allow the spring to rotate the threaded cam. This rotation is translated into axial motion by the treads on the threaded cam and threads formed on the inside of the housing. This axial motion forces an annular flange on the collet to bite down on the needle, to thus hold the needle in place in the shielded position.

摘要： A catheter introducer set is disclosed. The device comprises a cannula for insertion into a blood vessel, a tube in fluid communication with the cannula and a needle for assisting in the introduction of the cannula into the vessel. Between the cannula and the tube is an intermediate member which allows the needle to be gripped so that it can be inserted into the blood vessel. The intermediate member preferably has a pair of wings to facilitate the gripping of the needle. The needle has an opening or openings in it to allow a user to observe blood flashback during insertion of the needle into the blood vessel. The intermediate member is made of polyurethane and is provided with a groove to facilitate the gripping of the needle. The wings have ramps on them to facilitate the gripping of the needle. Ribs are also provided between the ramp and the intermediate member to facilitate gripping. The wings describe an angle of less than 180 degrees.
