技术领域 FIELD

[0003]当前系统、设备和方法与输液设备,尤其与静脉内(IV)导管有关。 [0003] Current systems, apparatus and methods and the infusion device, and in particular, intravenous (IV) catheter related. 具体来说,该系统、设备和方法与可冲洗外周静脉内导管组件有关,该组件具有能实现通过该导管组件的流体流的选择性激活的特征。 In particular, the system, apparatus and method with a rinse peripheral intravenous catheter assembly related to the assembly having features to achieve selective activation of the catheter assembly through the fluid flow.

背景技术 Background technique

[0004] 导管通常用于各种输液治疗。 [0004] Catheters are commonly used in a variety of infusion therapy. 例如,导管被用于输入流体,例如生理盐溶液、各种药剂、和肠外营养到病人体内,从病人抽血,或者监视病人的血管系统的各种参数。 For example, a catheter is used to input a fluid, such as physiological saline solution, pharmaceuticals, and parenteral nutrition to a patient, blood from the patient, or monitoring various parameters of the patient's vascular system.

[0005] 导管和/或针通常被联接到导管适配器以能实现IV管附接到导管。 [0005] catheters and / or needles are commonly coupled to the catheter adapter in order to achieve the IV tubing attached to the catheter. 因此,在将导管或针放置入病人的血管内后,导管适配器通过一段IV管联接到流体源。 Thus, after the placement of the catheter or needle into the vasculature of a patient, through the catheter adapter section of IV tubing is coupled to a fluid source. 为了验证针和/或导管被正确地放置在血管内,临床医生通常证明在导管组件的闪回室内有血液的“闪回”。 To verify the needle and / or catheter is properly placed within the blood vessel, the clinician generally proven flashback chamber of the catheter assembly with blood "flashback."

[0006] 在证明了导管的正确放置后,临床医生此时必须将导管适配器附接到一段IV管,或者继续手工地闭塞静脉以阻止向血液的不期望的暴露。 [0006] After proved correct catheter placement, the clinician must now be attached to the catheter adapter section of IV tubing, or venous occlusion continued manually to prevent undesirable exposure to the blood. 将导管适配器联接到一段IV管的过程要求临床医生不便地维持在病人的静脉上的压力,同时将导管适配器和IV管联接。 The catheter adapter coupled to a length of IV tubing inconvenient process requires the clinician to maintain pressure on the patient's vein, while the IV tubing and catheter adapter coupling. 通常的、但不受欢迎的实践是允许血液临时地且自由地从导管适配器流出,同时临床医生定位并联接IV管到导管适配器。 Typically, it is undesirable practice temporarily and permit blood flow freely from the catheter adapter, while clinicians IV tubing is positioned and coupled to the catheter adapter. 另一通常的实践是在将针或导管放置在病人的静脉之前将导管适配器附接到IV管。 Another common practice in the needle or catheter is placed before the patient's vein catheter adapter attached to the IV tube. 虽然这种方法可阻止不期望的向血液的暴露,但是IV线内的正压也可能阻止期望的闪回。 Although this approach may not be desirable to prevent exposure of the blood, but the pressure in the IV line may also be desirable to prevent flashback.

[0007] —些导管组件还利用隔膜致动器和开缝隔膜,其中隔膜致动器被机械地前移以通过隔膜中的狭缝以提供穿过隔膜的流动路径。 [0007] - Some of the catheter assembly further actuator and with the separator slit diaphragm, wherein the diaphragm actuator is mechanically forward through the flow path in the membrane to provide a slit through the septum. 但是,一旦被前移通过隔膜,隔膜致动器就卡在隔膜的狭缝内并且不能回到其初始位置。 However, once it advanced through a diaphragm actuator on the card in the slit of the septum and can not return to its original position. 因此,流体路径保持处于开放状态,并由此能实现穿过隔膜的不受控的流体流。 Thus, the fluid path remains in an open state, and thereby enables uncontrolled fluid flow through the membrane.

[0048] 在图1的备用位置中,针毂8的鼻部分被插入到导管毂2内。 [0048] In the standby position of FIG. 1, the nose portion of the needle hub 8 is inserted into the catheter hub (2). 中空的针9被固定到鼻部分并延伸通过阀7,导管毂2和导管管4,使得针尖9a被暴露在导管管4的锥形端外。 A hollow needle 9 is fixed to the nose portion and extending through the valve 7, the catheter tube 2 and catheter hub 4, such that the tip 9a is exposed to the outside of the tapered end of the catheter tube 4. 在针毂8和阀7之间并在导管毂2内,带有用以打开阀7的截头圆锥形定位部分或锥形鼻端IOa的阀打开设备或阀致动器10被可滑动地或可移动地布置,如在图2中所示。 In the valve 7 and the needle hub 8 between the hub and the catheter 2, with the valve opening for opening or frustoconical tapered nose IOa of the positioning portion 7 of the valve device or valve actuator 10 is slidably or movably arranged, as shown in FIG. 在阀致动器10的近端侧,设置柱塞部分或推杆端IOb以由医疗器具的阳型鲁尔圆锥配件推动,例如注射器尖端或IV管适配器,从而打开该阀。 The proximal side of valve actuator 10, a plunger or pusher end portion is pushed by the male to IOb medical instrument Luer taper fitting, such as a syringe or IV tubing adapter tip, thereby opening the valve. 推杆端IOb紧邻锥形鼻端10a。 IOb tapered nose proximate end of the push rod 10a. 在示例中,锥形鼻端IOa包含槽以促进与阀的接合,使得即使在医疗器具不再在阀致动器10上推动时,锥形鼻端保持与阀接合。 In an example, the nose cone comprising IOa grooves to facilitate engagement with the valve, so that even when the medical device no longer pushes on the valve actuator 10, the tapered nose engages the valve holder. 这被描述为图3中的阀致动器头210的带槽部分210b。 This is described as a grooved portion in FIG. 3 the valve head 210 of the actuator 210b. 如上面解释的,元件的典型交换可以是在图1和2的实施例中使用阀打开器210。 As explained above, a typical switching element may be used to open a valve 210 in the embodiment of FIGS. 1 and 2. 在一个示例中,仅有形成推杆端的单个元件或腿。 In one example, the push rod is formed only of a single element or leg end. 在另一示例中,提供了两个腿,它们之间有中空空间。 In another example, two legs, there is a hollow space therebetween. 两个腿的两个近端提供了由医疗器具推动的表面。 Two proximal two legs provides a surface driven by medical devices. 两个腿之间的空间被构造成接收针保护器元件13。 The space between the two legs are configured to receive a needle guard member 13. 换句话说,针保护器元件13被定位在两个腿之间的空间中。 In other words, needle guard member 13 is positioned in the space between the two legs. 在其它的示例中,具有空腔的第三壳体被定位在导管毂2和8的针之间。 In other examples, a third housing having a cavity is positioned between the needle 2 and the catheter hub 8. 针保护器元件13可被定位在第三壳体的空腔内并且第三壳体具有机械特征以接合导管毂和针毂。 Needle protector member 13 may be positioned within the cavity of the housing and the third housing having a third mechanical features to engage the catheter hub and needle hub. 在一些示例中,针保护器被省略并且导管组件仅包括阀和阀打开器。 In some examples, the needle protector is omitted and the catheter assembly includes only and valve opener.

[0049] 当在成功的静脉穿刺后从导管毂2撤回中空的针9时,在针尖9a附近提供的并具有在中空针上的径向突出(所述突出可由轻微的褶皱形成)形式的轮廓变化接合针保护器13的后壁13c中的空的外圆周,使得针保护器13被与针9 一起从导管毂移除。 [0049] When in the radial direction and having a hollow needle withdrawn from the hollow catheter hub 2 after a successful venipuncture needle 9, 9a provided in the vicinity of the tip protrudes (protrude slightly the pleats may be formed) in the form of a contour change engaging the rear wall 13c of the needle protector 13 in the outer circumference of the empty, so that the needle protector 13 is removed with the needle 9 from the catheter hub. 同时,针保护器的臂13a和13b覆盖针尖以防止针刺。 At the same time, the arms 13a and 13b of the needle protector covers the needle tip to prevent needle sticks. 在其它的示例中,轮廓的变化可包括在针的杆上的套、凹口、或材料堆积。 In other examples, the profile change may include a needle rod sleeve, notches, or deposited material. 在这个分开的状态中,阀7,由于其弹性,关闭了用于中空的针9的通孔,使得没有血液能够通过导管4流出。 In this disconnected state, the valve 7, due to its elasticity, a through hole for closing the hollow needle 9, so that no blood can be 4 flows through the conduit. 如下面参照图6和7进一步讨论的,本文提供的阀可包括三个狭缝54,它们开始于阀的中心并且在短径向距离上朝着外圆周径向延伸以形成弹性翻板,该翻板可由中空的针张开并且在针被移除时关闭。 6 as described below with reference to FIGS. 7 and discussed further, the valve provided herein may comprise three slits 54, which starts at the center toward the outer circumference of the valve and extending radially over a short radial distance to form a resilient flap which the flap may be opened and closed hollow needle when the needle is removed. 在一些示例中,翻板保持打开并与阀打开器接合。 In some examples, the flap valve is opened and kept open engagement.

[0050] 图2示出了将注射器14插入在导管毂2中,以通过导管毂注射流体,例如药剂,或抽吸体液样本,例如血液。 [0050] FIG. 2 shows the syringe 14 is inserted in the catheter hub 2 to the catheter hub by injecting a fluid, such as medicaments, or suction body fluid sample, such as blood. 如所示,注射器14的注射器尖端14a邻接阀致动元件10的推杆端IOb并且将其推动到阀7上,使得锥形鼻部分IOa打开狭缝7a,以由此打开阀,使得液体可从其流过。 As shown, the tip 14 of the syringes 14a adjacent to the valve actuator rod ends of IOb element 10 and push it into the valve 7, so that the tapered nose portion IOa open slits 7a, to thereby open the valve, so that liquid can be flow therethrough.

[0051] 如所示,致动器10的鼻端IOa是倾斜的。 [0051] As shown, the actuator 10 of the actuator IOa nose is inclined. 因此,当注射器被移除并且在致动器上的向前的力被移除时,阀7的材料的弹性足以使三个狭缝7a展开并且沿近端方向推动致动器以关闭密封件7。 Thus, when the syringe is removed and the actuator when the forward force on the actuator is removed, the valve 7 of the elastic material sufficient to expand the three slits 7a and pushes the actuator in the proximal direction to close the seal 7. 阀7因此在致动器上的推力撤回时自动关闭。 Thus the valve 7 is automatically closed when the thrust on the actuator withdrawn.

[0052] 肩部5a被不出在图1和2中的导管毂5内。 [0052] The shoulder portion 5a is not in FIG. 1 and 2 the catheter hub 5. 肩部5a在致动器上的凸缘邻接肩部时用作致动器10的止挡,这限定了致动器的最近端位置。 When activated shoulders 5a of the flange adjacent the shoulder on the actuator as an actuator of the stopper 10, which defines the most proximal position of the actuator. 在其它的示例中,第二毂部分可包含其它的结构特征,例如锥形内腔,以停止致动器的近端行进。 In other examples, the second hub portion may comprise other structural features, such as a conical lumen to the proximal end of the actuator travel stop.

[0053] 还示出,在毂元件5的空的内圆周内是第二肩部5b,其紧接在第一肩部5a的近端。 [0053] Also shown, it is an empty second shoulder 5b in the inner circumference of the hub element 5, which is immediately proximal end of the first shoulder 5a. 针保护器的弹簧臂的两个径向外部区域被构造成在图1的备用位置中邻接第二肩部5b。 Two radially outer region of the spring arms of the needle protector is configured to abut a second shoulder portion 5b at the standby position of FIG. 1. 当针毂8与中空的针9 一起被从导管毂2移除时,针保护器13由第二肩部5b基本上保持静止不动,直到在针附近的轮廓变化,例如褶皱,邻接针保护器的后壁并且针尖移到针保护器13上的两个远端壁的近端。 When the needle hub 8 together with the hollow needle is removed from the catheter hub 9 2, needle protector 13 remains substantially stationary by the second shoulder 5b, until a change in profile near the needle, for example folds, adjacent to the needle protection two on the proximal end of distal wall 13 and rear wall is moved to the needle tip protector. 此时,两个弹簧臂向内弹,以覆盖针尖并从第二肩部5b分离,此时针保护器13与中空的针9 一起可被从导管毂移除。 In this case, two elastic spring arms inwardly, so as to cover the needle tip and separated from the second shoulder 5b, the needle protector case 13 may be removed with the hollow needle 9 from the catheter hub. 关于针保护器13的更多信息在美国专利7736339中被讨论,其内容通过引用被明确地并入本文。 For more information on the needle protector 13 are discussed in U.S. Patent No. 7,736,339, the contents of which are expressly incorporated herein by reference.

[0054] 在根据图1和2的实施例中,第二毂部分5的远端部分在致动元件10和阀7被插入毂元件5内后被收缩、焊接或粘合到第一毂部分3的近端部分。 [0054] In the embodiment of FIGS. 1 and 2 according to the second distal end of the hub portion 5 of the actuating element 10 and the valve 7 is inserted after the contraction of the hub element 5, welded or glued to the first hub portion 3 of the proximal portion. 还可能的是,例如使用螺纹、干涉或卡口配合将两个毂元件3和5彼此连接。 It is also possible, for example, threads, interference fit or a bayonet the two 3 and 5 connected to each other hub member. 在组装期间针保护器13可通过毂的近端开口被与中空的针9 一起插入到毂元件5的孔5c内,其中弹簧臂的径向外部区域在弹性变形的作用下卡合在肩部5b中。 During assembly the needle protector 13 can be inserted together with the hollow needle 9 into the hole 5c of the hub element 5 through the proximal opening of the hub, wherein the radially outer region of the spring arm is elastically deformed under the effect of engaging the shoulder 5b.

[0056] 用于阻挡针尖272的尖端保护装置232被提供在第三壳体206内。 [0056] The needle tip protector for blocking the tip 272 of the third housing 232 is provided at 206. 在一个实施例中,第三壳体206包含了附接到壳体部分212以关闭在壳体部分212上的开口227的后板或面板208,其具有容纳针保护器的内腔。 In one embodiment, a third housing attached to the housing 206 contains a portion 212 on the portion 212 to close the opening of the housing plate 227 or rear panel 208 which has a lumen to accommodate the needle guard. 在壳体部分212上的开口227允许尖端保护装置232在组装期间被放置在其内。 In the upper portion of the opening 212 of the housing 227 allows the tip protector 232 is placed therein during assembly. 因此,当保护器被定位在第三壳体内时,其可相对于第三壳体移动。 Thus, when the protector is positioned within the third housing, which can move relative to the third housing. 可使用粘合剂、焊接或棘爪将后板208附接到壳体部分212。 Using an adhesive, welding or the detent plate 208 is attached to the rear housing portion 212. 替换地,壳体部分212可包含在一侧上的开口,其与后板208正交。 Alternatively, the housing may comprise an opening portion 212 on one side, which is perpendicular to the rear plate 208.

[0057] 在一个示例中,第三壳体206包括一对臂220,每个臂都包括钩214。 [0057] In one example, the third housing 206 includes a pair of arms 220, each arm 214 comprises a hook. 两个钩214被构造成接合在导管毂内部的环形隆起236,从而在准备使用的位置中将第三壳体206保持到导管毂202。 Two hooks 214 are configured to engage the interior of the catheter hub in the annular ridge 236, thus ready for use in the housing 206 to maintain the position of the third catheter hub 202. 两个臂220优选是弹性的,以提供在隆起236上的抓持力,这要比通过尖端保护装置232、止血阀207和导管204撤回针的摩擦力更高。 Preferably two resilient arms 220 to provide a gripping force on the ridge 236, this protection device 232 than through the tip, and a conduit 207 higher hemostasis valve needle 204 withdrawal friction. 替换地,两个臂220可被径向向外偏置以增加抓持力。 Alternatively, the two arms 220 may be biased radially outwardly to increase the gripping force. 另外,在针被撤到臂220的近端后两个臂可被向内偏置靠在针杆上以减小抓持力。 Further, after the needle is withdrawn to a proximal end of the arm 220 two arms may be biased against the needle shaft inward to reduce the gripping force. 仍然替换地,可使用单个臂来附接第三壳体到导管毂。 Still alternatively, a single arm may be used to attach the third housing to the catheter hub. 也可考虑外部结构特征来固定、固接或附接第三毂到导管毂,而不将臂伸到导管毂的内腔内。 Fixed, fastened or attached to the hub of the third catheter hub, without the arms out into the inner lumen of the catheter hub may also be considered an external structural features.

[0058] 在成功地导管插入后,针209被以和前面讨论相同的方式远离导管管204地向近端收回。 [0058] After successful catheterization, the needle 209 is discussed in the foregoing and in the same manner retract away from the catheter tube 204 proximally. 当针尖272移动到尖端保护装置232的远端壁的近端时,包括针尖开口222的尖端保护装置232接合针209并且针209的进一步向近端的运动引起尖端保护装置232被拉到第三壳体206的后板208上,这此后将两个钩214从两个隆起236脱离。 When the proximal end of the distal end wall 272 is moved to the tip of the needle tip protective device 232, including needle tip protector opening 222 engages the pin 209 and the needle 232 further proximal movement of tip 209 causes the third protector 232 is pulled the upper housing 208 the rear plate 206, after which the hook 214 is disengaged from the two two ridges 236. 因此,在两个钩214和两个隆起236之间的抓持力应该小于尖端保护装置232和针209之间的抓持力。 Thus, the grip force between the two hooks 214 and two ridges 236 between the gripping force should be less than 232 and a needle tip protective device 209. 在另一示例中,可使用带有被定为在第三壳体内的近端壁的保护器来接合针上的轮廓变化,与图1中的保护器类似。 In another example, the protector can be used as is with the inside wall of the third housing to engage the proximal end of the change in profile on the needle, similar to the protector 1 in FIG.

[0061] 图6和7描述了两个额外的阀实施例。 [0061] FIGS. 6 and 7 depict two additional embodiments of the valve. 两个阀40中的每一个都包括三个狭缝54,它们被形成为使得三个狭缝中每一个的一端都在阀中心的公共点56处连接。 Each of the two valves 40 comprises three slits 54, are formed which are connected to a common point at the center of the valve 56 is such that one end of each of the three slits. 这三个狭缝54限定了三个翻板320,它们可弯曲和不弯曲以打开通过阀的通道或关闭该通道。 The three slits 54 define three flap 320, which can be bent and unbent passage through the valve to open or close the passage. 翻板的可弯曲性,例如它们的弹性,可尤其依赖于狭缝的长度、材料、和阀的厚度。 Flexibility of the flap, for example their elasticity, in particular depend on the length, material, and thickness of the slit valve. 从这个公共点56,狭缝54径向向外延伸。 The slit 54 extends radially outwardly from the common point 56. 如所示,狭缝径向向外延伸但是不经过带有基础表面(图7)或孔隙周长306 (图6)的孔隙44的内周长316,这被定位在盘周长302的径向内部。 , The slit extending radially through the apertures but without having a base surface (FIG. 7) or aperture perimeter 306 (FIG. 6) of the inner perimeter 31 644 outwardly such that the perimeter of the disk 302 is positioned in the path to the inside. 狭缝围绕公共点56以约120度的均匀间隔隔开。 Slits spaced at regular intervals of about 120 degrees around a common point 56. 在其它的实施例中,狭缝可以不同的间隔围绕公共点设置,例如“T”构造或以120度以外的间隔。 In other embodiments, the slits may be spaced around a common point of different settings, for example, or configured in other than 120 degrees apart "T". 还可以是有多于三个的狭缝,例如4-6个狭缝。 There may also be more than three slits, for example slits 4-6. 还可以仅有一个狭缝,该狭缝延伸通过盘的中点以形成两个翻板。 It may also be only a slit which extends through the midpoint of the disk to form two flaps. 换句话说,单个狭缝可被看作是在盘的中点相遇的两个狭缝。 In other words, a single slit can be regarded as two slits meet at the midpoint of the disc. 还可以有“U”形狭缝,其中心也被设置在盘的中点上,但是狭缝不延伸通过中点。 There may also be "U" shaped slit whose center is also provided at the midpoint of the disk, but does not extend through the midpoint of the slit. 狭缝从近端表面42到远端表面52(见例如图4a和4b)地延伸穿过阀的宽度或厚度304,包括穿过孔隙44的任何部分,如果有孔隙的话。 The slit 42 extends from the proximal surface to the distal surface 52 (see e.g. FIGS. 4a and 4b) through the valve 304 to the width or thickness, including through any portion of the aperture 44, if it has pores. 狭缝被切割的长度等于阀的半径的长度的约0.25到约0.7。 The length of the slits are cut length equal to the radius of the valve from about 0.25 to about 0.7. [0062] 在一个示例中,通风口60可形成在阀40的周长302上。 [0062] In one example, the vent 60 may be formed on the circumference 302 of the valve 40. 在一些实施例中,有四个通风口60,它们被围绕着阀的周长以约90度的间隔隔开。 In some embodiments, there are four vents 60, which are spaced at intervals of about 90 degrees around the circumference of the valve. 其它的实施例考虑了在不同间隔距离处的不同示例的通风口或仅有一个通风口。 Other embodiments contemplate a vent or vents only exemplary different intervals at different distances.

[0063] 如在图6中所示,通风口60被从阀40的圆周周长302向内切割。 [0063] As shown in FIG. 6, 60 is a vent valve 40 from the circumferential perimeter of the cutter 302 inwardly. 通风口60被以锐角“A”切割,该锐角是从沿阀的圆周的切向延伸的直线测量的。 Vent 60 is at an acute angle "A" cutting, to the acute angle is measured from a straight line extending along the circumference of the cut valve. 在一个示例中,从切向延伸的直线测量的锐角是约45度,但是其它角度也被考虑,例如60度和30度或在它们之间的某个角度。 In one example, measured from a straight line tangential acute angle is about 45 degrees, but other angles are also contemplated, for example, 60 degrees and 30 degrees or an angle therebetween. 在一些实施例中,通风口是由沿着或靠近圆周周长302通过阀体300的简单的狭缝或简单的切口形成的。 In some embodiments, the vent 302 is close to the circumferential perimeter or along the valve body is formed by simple slits 300 or a simple incision. 在其它的实施例中,通风口60是V形凹口,例如图7中所示的。 In other embodiments, the vent 60 is a V-shaped recess, as shown for example in FIG 7. 每个V形凹口的缺口或大小是约10度或约15度,但是可以多达30度。 The size of each V-shaped notch or recess is about 10 degrees or about 15 degrees, but can be up to 30 degrees. 通风口的切口相对浅,从圆周周长302到狭缝的每个凹口的终端仅延伸阀的半径的长度的约0.1到约 Vent relatively shallow incision, about the length of the valve extending from each recess 302 to the perimeter of the circumference of the terminal slit only the radius to about 0.1

0.25。 0.25. 通风口被构造成在成功的静脉穿刺后允许空气从远端侧穿过到达阀的近端侧。 The vent is configured to allow air to pass through after a successful venipuncture to the proximal end side from the distal end side of the valve. 虽然图7的通风口看起来较大并且容易产生从其穿过的血流,但是在用致动器打开狭缝时,狭缝上的向外的力将迫使V形通风口关闭。 While FIG. 7 appears larger vent easily generated therefrom and the blood flow therethrough, but when the actuator opens the slit, the outward force on the slit force the vent closed V-shape. 这个关闭动作由图6中示出的箭头表示,这描述了当医疗器具被插入通过阀以打开狭缝时,施加到阀40的压缩力,如下面进一步讨论的。 The closing operation in the arrow shown in FIG. 6 indicates, when the medical device is described which is inserted through the slit valve to open, the compressive force applied to the valve 40, as discussed further below.

[0064] 本文讨论的阀可由任何弹性且柔韧或半柔韧的、适合医疗应用的材料制成,例如适合暴露给血液、药剂、和在输液程序中常遇到的其它流体。 [0064] The valves discussed herein may be resilient and flexible or semi-flexible, made of any suitable material for medical applications, for example, suitable for exposure to blood, medicaments and other fluids frequently encountered in the delivery program.

[0065] 在操作中,如在图2中所示,阀7由阀致动器10打开,阀7可以是本文其它处讨论的任意阀。 [0065], as shown in FIG. 2 in operation, the valve 7 by the actuator 10 to open the valve, the valve 7 may be any valve discussed elsewhere herein. 阀致动器10可由医疗器具插入导管毂2而位移或移动,例如阳型鲁尔构件或注射器14的尖端。 Valve actuator 10 may be inserted into the catheter hub medical apparatus 2 moves or is displaced, e.g. male luer tip member 14 or syringe. 在一些实施例准哦功能,阀7被阀致动器10的插入永久打开。 In some embodiments Oh registration function, the valve 10 is inserted into the valve actuator 7 are permanently open. 例如,如果阀致动器10的鼻端锥形鼻端IOa的尖端被插入通过狭缝足够深,那么狭缝将甚至在注射器被移除后保持打开。 For example, if the tip of the nose cone valve actuator IOa 10 of the nose is inserted through the slit deep enough, the slit remains open even after the syringe is removed. 这种更加永久的打开位置可进一步通过在致动器的鼻部分上包括凹部或槽210b以接合由狭缝形成的翻板320的一部分来促进。 This more permanent open position can further comprise a recess or groove 210b on the nose portion of the actuator to engage a portion of the flap formed by the slit 320 is facilitated by. 相反,当致动器10仅打开翻板320时,翻板是足够弹性的并且在撤回注射器时将不再弯曲以关闭并向近端移动致动器。 Conversely, when the actuator 10 is only open flap 320, the flap is sufficiently resilient and upon withdrawal of the syringe is no longer close to the proximal end bent to move the actuator.

[0066] 再次参照图6并且如前面提到的,当阀致动器被插入阀时,阀致动器在阀体300上施加径向向外的力,如箭头所示。 [0066] Referring again to FIG. 6 and as previously mentioned, when the valve actuator is inserted into the valve, the valve actuator radially outward force exerted on the valve body 300, as shown by the arrows. 径向向外指向的力,如箭头所指,使得阀体300径向向外地压缩在阀上的外部约束上,由此关闭了围绕周长的可能被打开的任何通风口60。 A radially outward directed forces, as indicated by the arrows, so that the valve body 300 radially outwardly compressed on the exterior constraint on the valve, thereby closing any vents 60 may be opened around the perimeter. 再一次,当阀致动器10进入阀40时,它通过从阀的近端表面或第一表面42远离导管毂的近端开口地朝着其远端或第二表面52运动来进入阀40(例如见图4a和4b)。 Again, when the valve actuator 10 into the valve 40, through which the proximal end of the catheter hub away from the proximal end surface of the valve opening or the first surface 42 toward its distal end surface 52 or second valve 40 into the movement (e.g., see FIG. 4a and 4b). 因为当阀致动器10进入阀40时其从近端到远端的运动,将使通风口60中每一个都从其近端侧逐步地关闭到其远端侧,即,沿着从其近端侧开始的深度逐渐地,以及从其径向最靠内的缺口逐渐地并且向外地到达其最靠外的径向缺口,在或靠近阀周长302。 Because when the valve actuator 10 from moving into its proximal end to the distal end of the valve 40, the vent 60 will allow each side gradually from its proximal end to its distal end side closed, i.e., along its start depth proximal end side gradually, and reaches its outward and radially outermost notch cutout therefrom radially innermost gradually, at or near the perimeter of the valve 302. 因此,通风口60从每个通风口的近端逐渐地关闭,对应阀40的近端表面42,直到每个通风口的远端,对应该阀的远端表面52,并且因此具有将任何血液从通风口60挤出的效果。 Thus, the vent 60 is gradually closed from the proximal end of each vent, corresponding to the proximal surface 40 of the valve 42, until the distal end of each vent on the distal surface of the valve 52 should be, and thus having no blood 60 extruded from the vent effect. 通过挤出动作去除血液将防止通风口中的凝结,这进而将减少了感染的可能性。 By removing the extrusion operation will prevent blood coagulation in the vent, which in turn reduces the likelihood of infection. 它还防止了溶血,这将导致血液样本不可用。 It also prevents hemolysis, which will result in a blood sample is not available.

[0067] 当通风口60打开时,阀,当用于导管应用时,可通风空气以允许一定的闪回。 [0067] When the vent 60 is opened, the valve, when used in catheter applications, may allow some air ventilation flashback. 当更大的压差被引入到阀的近端侧时,例如当用于收集血液样本的真空瓶或管被连接到导管毂时,或者,如在图2中所示,注射器14被连接且柱塞(未示出)被撤回时,血液由于压差而被朝着阀7抽吸。 When greater pressure is introduced to the proximal end side of the valve, for example, blood samples were collected when the vacuum bottle or tube is connected to the catheter hub, or 14 is connected as shown in FIG, 2 and the syringe a plunger (not shown) when it is withdrawn, since the blood pressure is sucked toward the valve 7. 在上述实施例的情况下,通风口60在阀致动器10的插入时被自动关闭,从而仅引导血液通过狭缝开口并进入注射器或真空瓶。 In the case of the above-described embodiment, the vent 60 is automatically closed when the valve actuator 10 is inserted, so that only the blood through the guide slit opening and into the syringe or vacuum flask. [0068] 图8是根据本公开的方面提供在导管毂(未示出但是类似图1的状态)内的阀40的示意横截面侧视图,针9通过通缝312伸出并且其中形成多个翻板320的多个狭缝64在备用状态相交。 [0068] FIG. 8 is provided in the catheter hub (not shown but similar to the state of FIG. 1) in a schematic cross-sectional side view of a valve 40 in accordance with aspects of the present disclosure, the needle 9 protrudes through the through slit 312 formed therein and a plurality of a plurality of intersecting slits 64 of the flap 320 in a standby state. 至少一个孔隙44被包含在阀40的近端侧42上,笔直的针杆62沿着通缝312靠在翻板320的内表面64上。 At least one aperture 44 is contained on the proximal side 42 of the valve 40, the needle bar 62 straight through the slit along the inner surface 320 of the flap 312 rests on 64. 由孔隙44的锥形表面310提供的锥形几何形状由于没有过多的材料挂靠在针上而允许翻板320不再弯曲,因此允许针杆62靠在内表面64上。 A tapered conical surface 44 of the aperture 310 geometry since no excess material anchored on the needle 320 to allow the flap was not bent, thus allowing the needle bar 62 against the inner surface 64. 在这个构造中,在缝312处的力向量,由图8中的箭头指示并由阀体300的弹性产生,更加垂直于针杆的轴线。 In this configuration, the force vectors of the slit 312, the valve body indicated by the arrow 300 in FIG. 8 to generate an elastic, more perpendicular to the axis of the needle shaft.

[0069] 如图9所示,当从阀表面省略了孔隙时,例如在利用仅带有狭缝以形成翻板而没有任何孔隙的标准的现有技术阀盘时,由箭头所指示的力向量更朝向近端或指向近端表面42。 When [0069] As shown, when the aperture is omitted from the valve surface, for example, using only the flap 9 with a slit to form a standard without any prior art valve disk apertures, the force indicated by the arrow more vector pointing towards the proximal end or a proximal surface 42. 尤其是,这是因为阀表面64的形成从近端外表面42到缝312的过渡部分66的那部分往往绕着与针9的接触点68旋转。 In particular, since the valve surface 64 is often formed around a contact point 68 of the needle 9 is rotated from the proximal transition portion 42 to the outer surface 312 of the slit portion 66. 形成孔隙消除了这个过渡部分66并允许针9沿着缝更加平衡且容易地滑动并且在更大的面积上与内表面64接触。 Eliminating the pore forming portion 66 and allows the needle 64 contacts the transition 9 slide along the slit and a more balanced and easily over a larger area of ​​the inner surface.

[0070] 因此,当在盘表面上包含一个或多个孔隙44时,可在轴向上中和阀对针杆的力。 [0070] Thus, when including one or more apertures 44 on a disk surface, and can force the valve needle shaft in the axial direction. 一个或多个孔隙可提供对在IV导管设备的消毒期间阀向近端拉针的问题的预料不到的解决方案。 One or more apertures may provide unexpected problem proximally pulling the needle valve IV catheter during sterilization device not solutions. 在正常条件下,在针上的轴向力由导管的锥形尖端在针杆上的抓持平衡。 Under normal conditions, the axial force on the needle holder by the catheter tapered tip balance grasping needle rod. 不过,在利用热和高湿的消毒期间,某些导管材料在针杆上的抓持会变弱并且可建立允许针由阀拉动的状态。 However, during sterilization using heat and high humidity, some of the catheter material grasping needle holding rod become weak and may allow the establishment of a valve needle pulled state. 这是不期望的效果,该效果可导致针斜面被拉到导管的锥形尖端内部。 This is an undesirable effect that can result in the needle being pulled to internal tapered bevel tip of the catheter. 这进而导致了向病人插入时很疼。 This in turn leads to pain when inserted into the patient.

[0071] 图10是根据本公开的多个方面的又一阀40s的端视图而图11是其横截面侧视图。 [0071] FIG. 10 is an end view of the present disclosure further valve in accordance with aspects of the 40s and FIG. 11 is a cross-sectional side view. 如所示,阀40包括在远端表面52上的加强肋70,这在本实施例中,被理解为是针出来的表面或侧。 As shown, the valve 40 includes a distal surface 52 on the ribs 70, which in the present embodiment, it is understood to be a needle or a side surface. 肋70增加了翻板处的阀的材料厚度并因此增加了翻板的刚性。 Rib 70 increases the valve flap at the thickness of the material and therefore increases the rigidity of the flap. 在一些实施例中,肋70是与阀的其余部分是相同材料,S卩,一体形成的本体。 In some embodiments, the rib 70 is a portion of the valve with the rest of the same material, S Jie, integrally formed body. 在其它的实施例中,肋可由相同或不同的材料制成并被连接到阀的本体。 In other embodiments, made of a material of the rib may be the same or different and is connected to the body of the valve. 例如,肋可与阀体一体形成,或者在它们被形成后被焊接到阀体。 For example, the ribs may be integrally formed with the valve body, or welded to the valve body after they are formed.

[0072] 在使用中,图10的阀40如常地由阀打开器打开,如在图2中所示。 [0072] In use, the valve 10 is opened by the valve 40 as usual open, as shown in FIG. 当移除注射器时,肋70将增加翻板320上的弹回动作,以增加阀的关闭力,从而容易地沿近端方向推动阀致动器10。 Upon removal of the syringe, the ribs 70 increase the spring action on the flap 320 to increase the valve closing force, thereby easily valve actuator 10 pushing the proximal direction.

[0073] 如在图11中所示,肋70沿径向向外方向从远端表面52的中心56起在阀40的圆周周长72的方向上形成斜坡或倾斜到远端延伸位置。 [0073] The 56 together form shown, the ribs 70 radially outward direction from the center of the distal surface 11 in FIG. 52 in the direction of the circumferential perimeter 40 of the valve 72 to the distal end of the inclined ramp or extended position. 在其它的实施例中,斜坡可以是相反的。 In other embodiments, the ramp may be reversed. 在一些示例中,每个肋的上表面76可以是直的、凹形的、凸形、或它们的组合。 In some examples, the upper surface of each rib 76 may be straight, concave, convex, or a combination thereof. 每个肋70的起点78也可正好开始于阀的中心56,而不是与该中心间隔开或从该中心凹入。 78 of the start of each rib 70 may be started right at the center of the valve 56, instead of spaced apart from the center or from the central recess. 在又一示例中,近端表面42可包括孔隙44,类似于图4a或4b中所示的。 In yet another example, the proximal surface 42 may include apertures 44, similar to that shown in Figures 4a or 4b. 还进一步,围绕外周长可包括通风口,类似于图6和7所示的。 Further, around the outer perimeter of the vent may comprise, similar to FIG. 6 and 7.

[0074] 如图12中所示,阀600也可被具体化为圆柱。 [0074] As shown in FIG. 12, the valve 600 may also be embodied as a cylinder. 阀600包括盘602,该盘具有第一或远端表面642、第二或近端表面652、和将这两个表面分开的厚度,这类似于图4a的厚度304。 Valve 600 comprises a disk 602, the disk has a first or distal surface 642, a second or proximal surface 652, and a thickness separating these two surfaces, which is similar to a thickness of 304 4a. 盘602被定位在中空圆柱部分603的端部处,该圆柱部分具有长度和本体壁厚度,该厚度限定了内部空间并具有中空的或敞开的第二端677。 Disc 602 is positioned at the end portion of the hollow cylindrical portion 603, the cylindrical portion has a length and a body wall thickness, the thickness defining an interior space and having a hollow or open second end 677. 盘602可类似或包括上面讨论的带有阀狭缝654和孔隙、肋和通风口的各种构造的阀盘实施例中的任一个的特征。 Plate 602 may be similar or include any of the features of the embodiment with the valve disc 654 and valve slit aperture various configurations, ribs and vents the embodiment discussed above. 在本实施例中,通风口660被包含在中空圆柱部分603中并且在圆柱的整个长度上延伸并且通向圆柱的外周长672。 In the present embodiment, the vent 660 is included and extends and opens into the cylindrical outer circumference of the cylinder 672 over the entire length of the hollow cylindrical portion 603. 通风路径可以是笔直的或弯曲的。 Vent path may be straight or curved. 阀600可通过简单地将该阀滑入导管毂的内腔且盘表面652面对导管毂的近端开口而与许多导管组件一起使用。 652 valve 600 may face the opening of the proximal end of the catheter hub used with many of the catheter valve assembly by simply slid into the lumen of the catheter hub and the disc surface. 可使用台阶销工具来将阀推入导管毂。 Pin tool may be used to step the valve push catheter hub. 销工具的更小的尖端可进入阀的圆柱部分603以推动近端表面652并且更大的台阶直径部分可推在圆柱部分603的近端表面607上,以定位阀600在导管毂内。 Smaller pin tip tool may enter the valve 603 to push the cylindrical portion 652 and a proximal surface of the larger diameter of stepped portion can be pushed on the proximal surface 607 of the cylindrical portion 603 of the valve 600 to be positioned within the catheter hub.

[0075] 如在图13中示出的,中空圆柱部分603具有外径OD和限定了孔605的内径ID。 [0075] As shown in FIG. 13, the hollow cylindrical portion 603 having an outer diameter OD and an inner diameter defining a bore 605 of the ID. 在一些实施例中,孔605的内壁682是光滑的。 In some embodiments, the inner wall 682 of bore 605 is smooth. 在其它的实施例中,内壁682是带纹理的。 In other embodiments, the inner wall 682 is textured. 在一些实施例中,圆柱的壁610围绕周长672是均匀厚度的,除了在通风口位置。 In some embodiments, the cylindrical wall 610 around the perimeter 672 is of uniform thickness, except in the vent position. 在其它的实施例中,壁610可形成为具有变化的厚度,这限定了孔605的形状。 In other embodiments, the wall 610 may be formed of varying thickness, which defines the shape of the hole 605. 通风口660被切到圆柱壁610的厚度约一半的深度。 Vent 660 is cut to a thickness of the cylindrical wall 610 is about half the depth. 狭缝654和对应的翻板620穿过阀盘部分602的厚度并且通向中空的圆柱部分603。 The corresponding slits 654 and 620 through the thickness of the flap valve disk 602 and opens into the hollow portion of the cylindrical portion 603.

[0076] 如在图14中所示,中空的圆柱壁610限定了近端面607。 [0076] As the hollow cylindrical wall 610 as shown in FIG. 14 defines a proximal face 607. 如上讨论地,狭缝654和对应的翻板620穿过阀盘的厚度并且可从近端看见。 As discussed above, the slits 654 and 620 through the thickness of the corresponding flap valve disk and visible from the proximal end. 同样地,通风口660延伸阀的长度L并且通风口661的近端是可见的。 Similarly, a length L extending vent valve 660 and proximal end 661 of the vent are visible.
