[0116] 图46示出的实施例中,一个或多个凸起部分238围绕细长部件212的直径缩小的近端部分216沿圆周分布。 [0116] FIG. 46 embodiment illustrated embodiment, one or more raised portions 238 of the reduced diameter proximal portion 212 of the distribution 216 circumferentially around the elongate member. 一个或多个凸起部分238的尺寸使得其与弹簧夹220的底部118中的孔119相互作用,以便阻碍底部118在近端部分216上的向远侧的轴向前进直到施加足够大的力来克服孔119的圆周区域与一个或多个凸起部分238之间的阻力。 One or more dimensions of the protrusion portion 238 such that it interacts with the spring clip 220 in the bottom 118 of the hole 119, the bottom 118 to restrain forward until sufficient force is applied in the axial direction on the proximal end of distal portion 216 resistance between the portion 238 to overcome the hole 119 in the circumferential region with one or more projections. 在一些实施例中,底部118的对孔119加以界定的部分可基于一个或多个凸起部分238施加至其上的力而变形, 以便在细长部件被向近侧抽拉时有助于孔119前进并超过一个或多个凸起部分238。 In some embodiments, the bottom of the hole 119 to be 118 pairs defining portion 238 may be raised portion is applied thereto on one or more forces on deformed to facilitate the elongate member is drawn when proximally hole 119 and advances or more than one raised portion 238. 在一些实施例中,一个或多个独立的凸起部分238被凸起的环形圈所替代。 In some embodiments, a plurality of independent projections or replaced projection portion 238 is an annular ring.

[0117] 在另一些实施例中,通过使用位于细长部件的近端部分上的环形凹部254,弹簧夹220在准备位置被至少部分地保持在细长部件上。 [0117] In further embodiments, by use of an annular recess 254 located on the proximal portion of the elongated member, the spring clip 220 is held in a ready position on the elongated member at least partially. 图47示出了具有远端部分251和直径缩小的近端部分252的细长部件250。 FIG 47 shows an elongated member 250 having a distal end portion 252 and a reduced diameter portion 251 of the proximal end. 直径缩小的近端部分252的直径通常大于弹簧夹220的底部118中的孔119的直径。 The diameter of the reduced diameter proximal portion 252 of the hole 119 in the spring clip 118 is generally greater than 220 at the bottom. 位于直径缩小的近端部分252的之内的是环形凹部254,所述环形凹部254的尺寸使其能够容纳弹簧夹220的底部118的对孔119加以界定的部分。 Within the proximal portion 252 located at reduced diameter portion 254 is an annular recess, the size of the annular recess 254 of the base 220 so as to be 118 pairs of holes 119 defined in the receiving portion can be a spring clip. 底部118的完全地或部分地对孔119加以界定的部分具有足够的弹性,以在弹簧夹220最初被装载到细长部件250的近端部分252时允许孔119的直径扩大。 Completely or partially the bottom 118 of the hole 119 to be defined portion having sufficient resiliency to spring clip 220 is initially loaded into the proximal portion of the elongated member 250 allows the diameter of the bore 119 252 enlarged. 底部118的对孔119加以界定的部分还具有足够的弹性,以在足够大的力被施加到底部118上时允许孔119的直径扩大并移动出环形凹部254并且沿着细长部件250的直径缩小的近端部分252向远侧前进。 The bottom 118 of apertures 119 defined to be the portion further has a sufficient resiliency to be applied when in the end portion 118 allows the diameter of the enlarged hole 119 and moved out of the annular recess 254 and the diameter of the elongated member 250 along a sufficient force in narrow proximal portion 252 advances distally. 这种构造的优点在于:当弹簧夹220被启用以覆盖细长部件250的远端225时,弹簧夹220的底部118与近端部分252之间的挤压配合使得弹簧夹220在细长部件250上的轴向移动和径向移动被阻碍或被最小化。 The advantage of this configuration is that: When the spring clip 220 is enabled to cover the distal end 225 of the elongated member 250, the spring clip 118 and squeezed between the proximal portion 252 with the bottom 220 of the spring clip 220 such that elongated member axial movement and radial movement 250 is inhibited or minimized.

[0118] 图48示出了与图47的细长部件250相似的细长部件260,其中,细长部件260拥有环形凹部264,所述环形凹部264用于容纳底部118的对孔119加以界定的部分。 [0118] FIG. 48 shows similar to FIG. 47 of the elongated member 250 of the elongated member 260, wherein the elongated member 260 has an annular recess 264, the annular recess 264 for receiving the bottom portion 118 of the hole 119 to be defined part. 细长部件260和细长部件250之间的差别在于,细长部件260沿其长度具有大致均匀的截面。 The elongated member 260 and elongate member 250 in that the difference between, the elongated member 260 has a substantially uniform cross-section along its length.

[0119] 图49A示出了根据另一个实施例的细长部件270。 [0119] FIG 49A illustrates elongated member 270 according to another embodiment. 细长部件270具有远端部分271和近端部分272。 The elongated member 270 has a distal portion 271 and proximal portion 272. 近端部分272包括直径缩小的近端部分273和截头锥部分274,所述截头锥部分274的直径从其近端275处的缩小的直径尺寸过渡至其远端276处的较大的直径。 A reduced diameter proximal portion 272 includes a proximal portion 273 and frustoconical portion 274, a reduced diameter from its proximal end 275 of the frustoconical portion 274 of the transition to a larger diameter at its distal end 276 diameter. 在一个实施例中,所述远端276处的直径至少等于细长部件270的远端部分271的直径。 In one embodiment, the diameter at least equal to the diameter of the distal end 276 of the elongated member 270 distal section 271. 如图49B中所示,在一个实施例中,弹簧夹220被组装到细长部件270上,使得直径缩小的近端部分273 延伸穿过底部118中的孔119。 As shown in FIG. 49B, the one embodiment, the spring clip 220 is assembled to the elongated member 270, such that the reduced diameter proximal portion 273 extends through an aperture in the bottom of 118,119. 在一些实施例中,孔119的直径仅仅略大于近端部分273的外径。 In some embodiments, only slightly larger than the diameter of the bore 119 of the outer diameter of the proximal portion 273. 在另一些实施例中,孔119的直径以及近端部分273的外径被选择成使得在孔119的边缘与近端部分273的外表面之间产生摩擦配合,通过摩擦配合允许孔119的边缘与近端部分273的外表面之间的滑动关系。 In other embodiments, the diameter of hole 119 and the outer diameter of the proximal portion 273 is selected so that the friction fit between the outer surface of the edge of the proximal portion 273 of the hole 119, through hole 119 to allow a friction fit of the edge and sliding relationship between the outer surface of the proximal portion 273. 在另一些实施例中,在将弹簧夹220和细长部件270组装到一起之前,孔119的直径小于近端部分273的外径。 In other embodiments, the elongated member 220 and the spring clip 270 prior to assembling the diameter of the hole 119 is smaller than the outer diameter of the proximal end portion 273 together. 以与前述相似的方式,在该实施例中,底部118的至少完全或部分地对孔119加以界定的部分是可变形的(塑性的和/或弹性的),以便允许孔119的直径与近端部分273的外径相配。 As in the previous similar manner, in this embodiment, at least the bottom entirely or partially 118 be part defining the aperture 119 is deformable (plastic and / or elastic) to allow hole 119 to the diameter of the near the outer diameter end portion 273 match. 底部118和近端部分273的材料以及尺寸特征允许通过施加最小的轴向力来实现底部118和近端部分273之间的滑动关系。 Wherein the base materials and the dimensions 118 and a proximal portion 273 allows for minimal axial force is achieved by applying a sliding relationship between the base 118 and a proximal portion 273.

[0120] 在一个实施例中,在准备位置,弹簧夹220的底部118位于截头锥部分274的近端275处,而在另一些实施例中,底部118位于近端部分273上(如图49C所示)。 [0120] In one embodiment, in the ready position, the bottom 220 of spring clips 118 at the proximal end of the frusto-conical portion 274 at 275, while in other embodiments, bottom portion 118 located on the proximal end portion 273 (FIG. FIG 49C). 在使用中,在所述导管710适当地进入到患者的血管中的基础上,所述针衬套704被朝近端抽拉,以使所述针尖134从患者体内撤回并进入所述针套中。 In use, on the basis of the patient's blood vessel into the catheter 710 is suitably on the needle hub 704 is proximally drawing, so that the needle 134 is withdrawn from the patient and into the needle guard in. 随着针被收回,针套通过突出部116,117施加的向外的力而被固定在导管衬套702的内部,于此同时,弹簧夹220通过底部118与细长部件270的近端部分272的相互作用而被轴向地保持在细长部件270上。 As the needle is retracted, the needle guard inside the catheter is fixed to the bushing 702 by the outward force exerted by the protruding portions 116 and 117, the same time, the spring clip 220 through the proximal portion of the elongated member 118 and a bottom 270 interaction 272 is axially retained on the elongated member 270. 当针130的轮廓变化处132被止挡在细长部件270的内部时,凭借底部118的如上所述的可变形特性,被施加至针衬套704的持续的向近侧的力M致使弹簧夹220的底部118向远侧前进到截头锥部分274上。 When the change in profile 130 of the needle 132 is positioned within the elongated stop member 270, with the deformable characteristic of the bottom 118 as described above, is applied to the continuous force M of the needle hub 704 proximally causes the spring clip 220 onto the base 118 proceeds frusto-conical portion 274 distally. 在一个实施例中,底部118的向远侧持续地前进直到到达截头锥部分274的远端276或远端部分271的近端。 In one embodiment, the continuously advancing until reaching the distal end of the proximal frustoconical portion 274 or distal portion 276 271 118 bottom distally. 恰好在底部到达其在细长部件270的近端部分272的最远侧的位置之前或同时,针130的远端针尖完全进入细长部件270并且弹簧夹220的唇缘部分111和112前进并超过细长部件的远端278 (如图49D所示),以便件针尖134安全地固定在细长部件之内。 Just prior to its reaching the bottom position of the elongated member proximal of the distal-most portion 270 or 272 while the distal end 130 of the needle tip fully into the elongated member 270 and lip portion 220 of the spring clip 111 and 112 and proceeds beyond the distal end of the elongated member 278 (shown in FIG. 49D), the tip member 134 to secure the elongate member within the secured. 这种构造的优点在于:当弹簧夹220被启用以覆盖细长部件270的远端278时,弹簧夹220的底部118 与截头锥部分274的远端276之间的挤压配合使得弹簧夹220在细长部件270上的轴向移动和径向移动被阻碍或被最小化。 The advantage of this configuration is that: When the spring clip 220 is enabled to cover the distal end 270 of elongate member 278, the spring clip 118 squeezed between the bottom portion 276 and 220 of the distal frusto-conical portion 274 such that the spring clip with 220 axial movement and radial movement on the elongated member 270 is inhibited or minimized.

[0121]图50示出的细长部件280具有与细长部件270相似的构造。 [0121] FIG. 50 shows an elongated member 280 has a similar configuration of the elongated member 270. 不同之处在于,包含位于远端部分274处或远端部分274附近的止挡部284。 Except that, at the distal end portion 274 comprises a distal portion 274 or the stopper portion 284 nearby. 止挡部284可以是如图50中所示的环形圈的形式,或可以包括一个或多个围绕细长部件280的外周分布的凸起部分。 Stop 284 may be in the form of an annular ring as shown in FIG. 50, or may include one or more raised portions 280 around the outer periphery of the elongate member profile. 止挡部284的直径大至足以绝对地阻止弹簧夹底部118前进超越该止挡部。 Diameter stopper portion 284 is large enough to definitely prevent the spring clip 118 advances beyond the bottom stopper portion.

[°122]图51示出的细长部件290类似于细长部件270,除了整个近侧远端部分272呈截头锥构造。 [° 122] FIG elongate member 51290 is similar to the elongated member 270 illustrated, the distal end portion 272 as a whole in addition to proximal frustoconical configuration.
