具有分离式隔离组件的封闭型留置针导管组件 Closed isolation assembly having separate catheter indwelling needle assembly

技术领域 FIELD

[0001] 本发明涉及一种将介质引入体内的器械,特别是一种具有分离式隔离组件的封闭型留置针导管组件。 [0001] The present invention relates to a medium introduced into the body of the instrument, in particular a closed separate isolation assembly having a catheter indwelling needle assembly.

背景技术 Background technique

[0002] 封闭型留置针包括有针管组件和导管组件,其中针管组件包括有针管及针座,针管为中空,其前端部开具有回血槽;导管组件包括有透明或者半透明中空的导管、导管座、隔离组件以及延长管接头,导管的一端部与导管座连接,针管穿过导管座内腔并插接在导管腔中,隔离组件为一种具有一定长度的隔离塞,其以紧配合方式安装在导管座内腔;在隔离塞的作用下,导管座内腔在隔离塞前形成一个回血腔,该回血腔与延长管接头连通。 [0002] CSG indwelling needle comprises a needle cannula assembly and a catheter assembly, wherein the needle assembly comprises a needle cannula and a needle hub, the needle is hollow, the front end portion of the opening having a return blood reservoir; catheter assembly comprising a transparent or translucent hollow conduit, the conduit Block, isolation assembly and the extension pipe joint, an end portion of the catheter is connected to the catheter hub, the needle inserted through the catheter housing and lumen in the catheter lumen, the isolation assembly is a spacer plug having a length, which is a close fit mounted in catheter hub lumen; plug in isolation, the catheter hub lumen of a blood chamber formed in front of the separating stopper, the blood return lumen in communication with the extension pipe joint.

[0003] 在临床使用中,中空的针管刺入血管后,在血压的作用下,必然会有一些血液经由针管上的回血槽进入针管的空腔中并滞留在其中,此时针管腔中的压力相当于人体的血压,当留置针穿刺并置管成功后,针管需要后撤推出导管组件,在后撤的过程中,一旦针管的回血槽退到隔离塞后端面外,针管腔内外压力失衡,其中的血液容易通过回血槽喷出,弓丨发血液污染问题,尤其是大直径规格的留置针问题更严重。 [0003] In clinical use, the hollow needle piercing the vessel, under the blood pressure, there must be some of the blood into the lumen of the needle tube and retained therein via the blood back groove on the needle, when the needle lumen pressure corresponding human blood, when successful catheterization and indwelling catheter, the needle needs to retreat out of the catheter assembly, during the retreat, once the needle back to the blood tank retreated septum outer end face, the pressure inside and outside the lumen of the needle imbalance, which easily through the blood back to the blood trough spray, hair bow Shu blood pollution, especially in large diameter sizes catheter problem is more serious.

[0004] 现有技术的问题还在于:由于留置针的隔离塞都是采用弹性材料制成,针管在穿过导管座内腔时,是以压迫方式穿刺通过隔离塞的,此时隔离塞产生压迫变形,形成一通道供针管穿过,因此隔离塞在与针管外表面长期接触压迫下所形成的通道在针管撤出导管组件后不会瞬间闭合,导致回血腔中为观察回血而滞留的血液通过该通道溢出隔离塞后端面,引发另一种血液污染问题。 [0004] The problems of the prior art in that: Since the indwelling needle septum is made of an elastic material, when the needle passes through the lumen of the catheter hub, is produced by compression of puncturing the septum, then separating stopper compression deformation, forming a passage for the needle to pass through, thus isolating the channel stopper under prolonged contact oppression and the outer surface of the needle tube is formed not instantly closes after needle withdrawal catheter assembly, leading back to the blood chamber to observe the blood back and stays in the blood through which the end face of the separating stopper overflow, causing another problem of blood contamination.

发明内容 SUMMARY

[0005] 本发明的目的在于根据现有技术的不足之处而提供一种能够解决临床使用中的血液污染问题的具有分离式隔离组件的封闭型留置针导管组件。 [0005] The object of the present invention is to provide a closed spacer having a separate assembly which can solve the problem of blood contamination of the clinical use of a catheter indwelling needle assembly according to the shortcomings of the prior art.

[0006] 本发明是通过以下途径来实现的: [0006] The present invention is achieved by the following ways:

[0007] 具有分离式隔离组件的封闭型留置针导管组件,包括有中空的导管、导管座、隔离组件以及延长管接头,导管的一端部及延长管接头的一端部分别与导管座连接,前端开具有回血槽的针管穿过导管座内腔并插接在导管腔中,隔离组件包括第一隔离塞,其以紧配合方式安装在导管座内腔;第一隔离塞的前端与导管座内腔形成回血腔,该回血腔与延长管接头连通,其结构要点在于,隔离组件还包括第二隔离塞,其安装在导管座内腔的后端部,第一隔离塞的后端面与第二隔离塞的前端面之间在导管座内腔形成一种容血腔。 [0007] closed with separating type isolation assembly indwelling needle catheter assembly comprising a hollow catheter, the catheter hub, the spacer assembly and the extension pipe joint, an end portion of the catheter and the end of the extended portion of the pipe joint are respectively connected to the catheter hub, the distal end a needle tube having open slots through the blood return lumen catheter hub and the catheter inserted in the cavity, the isolation assembly comprising a first septum, which is mounted in a tight fit manner the catheter hub lumen; and a first spacer plug distal catheter hub lumen back to the blood chamber is formed, the blood return lumen in communication with the extension pipe joint, wherein the structure elements, a second isolation assembly further comprises a septum, which is mounted at a rear end portion of the catheter hub lumen, the first spacer and the rear end surface of the plug between the distal end surface of the plug to form a second isolation chamber volume of blood in the lumen of the catheter hub.

[0008] 在第一隔离塞和第二隔离塞之间所形成的容血腔为密闭腔,其中的气压都是低于回血腔压力。 [0008] The blood receiving chamber between the first and second septum plug formed is isolated tight chamber in which the blood pressure is lower than the back pressure chamber. 在临床使用中,针管穿刺并置管成功后,需要撤离导管组件,此时,针管上的回血槽一旦进入容血腔,针管内腔的血液就会很快通过回血槽和针尖释放在该容血腔中;即使第一隔离塞的针管通道未能瞬间密闭,回血腔中的小部分血液也只能滞留在容血腔中,不会溢出导管座外,这样容血腔就为封闭型留置针使用过程中可能产生的血液外溢提供了一个容纳空间,从而杜绝了血液污染问题。 After clinical use, the needle puncture and catheter successful, the need to evacuate the catheter assembly, this time back to the blood groove on the needle tube once into the receiving blood chamber, the blood needle lumen will quickly release the container through the return blood groove and tip blood chamber; even if the first septum needle tube channel failed instantly closed, a small portion of the blood back to the blood chamber can only stay in the blood receiving chamber, does not overflow outside the catheter hub, so that the blood receiving chamber is closed to the indwelling blood may occur during use of the needle spillover provide a receiving space, thus eliminating the problem of blood contamination.

[0009] 针管的针尖和回血槽之间有一定距离,在撤针的时候,回血槽进入容血腔后,针尖可能还留在回血腔中,这样,针管就会在在容血腔和回血腔之间形成一个通道,但由于时间较短,且第二隔离塞与针管始终保持密闭状态,因此回血腔中的血液能够流到容血腔中的有限,当针尖离开第一隔离塞后,就可以完全阻隔回血腔和容血腔。 There is a certain distance between the tip [0009] The needle tube and back to the blood tank when the withdrawal of the needle, and back to the blood tank into the receiving blood chamber, the needle may remain in the blood back to the chamber, so that the needle will be in the receiving blood chamber and back to the blood a passage is formed between the chamber, but due to the short time, and the second septum and the needle tube remains closed state, so the blood back to the blood chamber of a limited volume of blood can flow chamber, after the needle tip away from the first separating stopper, You may completely block blood back to the blood chamber and the receiving chamber.

[0010] 本发明可以进一步具体为: [0011] 隔离组件还包括有隔离管,其安装在容血腔中,隔离管的管腔轴线与导管座的内腔轴线平行,并与导管座内腔壁之间为间隙配合,隔离管的前端面紧靠第一隔离塞,后端面紧靠第二隔离塞。 [0010] The present invention may be more specifically as follows: [0011] The isolation assembly further comprises a spacer tube which is mounted in the blood receiving chamber, the axis of the lumen of the lumen and catheter hub axis is parallel to the spacer tube, with a lumen catheter hub clearance fit between the walls, the front end surface of the spacer tube against the first septum, the rear end surface abuts against the second septum.

[0012] 这样可以固定第一隔离塞和第二隔离塞之间的位置,保证足够容血腔的空间,形成具有稳定构造的分离式隔离组件。 [0012] Such a position may be fixed between a first spacer and a second spacer plug stopper to ensure sufficient space accommodating the blood chamber is formed separate spacer assembly having a stable configuration.

[0013] 导管座的后端面上具有一端盖,其外周与导管座后端沿内腔侧壁紧密配合,第二隔离塞的后端面紧贴在该端盖的内侧面上。 [0013] surface of the rear end cap has a catheter hub, the rear end of the outer periphery of the catheter hub with a tight fit in the lumen of the side walls, the rear end surface of the second septum close contact with the inner surface of the end cap.

[0014] 端盖还可以进一步采用粘接等紧固方式与导管座进行固接。 [0014] The cap may further be affixed to the catheter hub using an adhesive fastening means and the like. 端盖起到为整个隔离组件提供限定位置的作用,在使用过程中,隔离组件不会脱出导管座,也保证了分离式隔离组件之间的密闭。 Cap functions to provide a defined position for the entire insulation assembly action, during use, catheter hub isolation assembly not to come out, but also to ensure the hermetic isolation between the separate components. 这样就可以提供更高输液液体压力,方便了高压输液场合。 This can provide a higher pressure of the infusion liquid to facilitate the high pressure infusion applications.

[0015] 第二隔离塞可以是一种与第一隔离塞一样的塞件,还可以是: [0015] The second septum may be isolated as a first stopper plug, it may be:

[0016] 第二隔离塞为一种吸血塞。 [0016] Second septum plug into a vampire.

[0017] 吸血塞采用高吸液的医用级材料制成,能够吸收血液中的水分并迅速膨胀形成不透水的堵塞,在针管后撤的过程中,其本身不存在留有针管后撤通道问题。 Formed [0017] using high liquid sucking plug of medical grade materials, water can be absorbed in the blood and rapidly expands to form a water-tight plugging, during retreat of the needle, the needle does not itself leave evacuation channel Problems . 因此吸血塞可以吸收容血腔中的血液,甚至将针管外表面的血溃都能够吸收干净,也就更进一步杜绝了血液污染的问题。 Thus the plug can absorb blood sucking blood receiving chamber, the blood will collapse even external surface of the needle tube can absorb a clean, will further eliminate the problem of contaminated blood.

[0018] 综上所述,本发明提供了一种可以杜绝留置针使用过程中血液污染问题的封闭型留置针导管组件,其提供了一种分离式隔离组件,在隔离组件中提供一种具有前后隔离塞的容血腔,其为封闭型留置针使用过程中可能产生的血液外溢提供了一个隔离的容纳空间,为隔离血液提供了进一步的隔离保障,从而杜绝了血液污染问题。 [0018] In summary, the present invention provides an indwelling needle can eliminate the use of a catheter indwelling needle assembly closed blood contamination problem, there is provided a separate isolation assembly to provide a separator assembly in septum before and after blood volume of the chamber, which is closed indwelling needle may be generated during use of blood spills provide a receiving space isolation, isolation providing further protection for the isolation of blood, thus eliminating the problem of blood contamination.
