The utility model discloses an automatic exhaust infusion needle seat, which comprises an external infusion tube, an internal infusion tube is sleeved in the cavity of the upper part of the external infusion tube, the upper end of the internal infusion tube extends along the external infusion tube, the extension end of the internal infusion tube connects the needle, the lower end of the internal infusion tube is fixed on the external infusion tube, the lower end of the internal infusion tube connects the self-exhaust component, and the self-exhaust component consists of the side wall and the bottom end. The self-exhaust assembly is communicated with the infusion inner tube. The lower part of the side wall of the self-exhaust assembly is provided with through holes, and there is a gap between the side wall of the self-exhaust assembly and the inner wall of the infusion outer tube. The utility model fixes the self-exhausting component at the bottom of the inner pipe for infusion, and the lower part of the side wall of the self-exhausting component is provided with through holes, so that air will float on the bottom of the inner pipe for infusion because the density of the air is smaller than the density of the liquid, and the liquid will enter the inner pipe for infusion from the through holes, so as to achieve the purpose of automatic exhaust. The utility model can realize the automatic exhaust of the needle seat and the structure. Simple, low cost, suitable for clinical application.
【技术实现步骤摘要】
一种自动排气的输液针座
本技术涉及临床输液用的无菌医疗器械,具体涉及一种自动排气的输液针座。
技术介绍
普通输液器在输液刚开始时,药液通过管路从滴管流出,进入滴斗,液体易将滴斗内的气体向下排出形成气液混合物进入管路,而产生气泡,通过导管的管路进入针座。目前,临床用的输液针座如图1所示,输液外管2内套有输液内管3,输液外管2和输液内管3直接相通,气泡会经输液外管2直接进入输液内管3,从而通过针头进入人体,易造成气栓等危害。同时,因输液管路内壁的表面张力作用,输液导管的内壁易吸附少量的气泡,且排除由此产生的气泡过程较为困难、费时和繁琐。然而,人工排气泡的过程既繁琐又费时,不利于紧急输液和抢救病人,而且现有的可过滤空气或自动排气的输液装置结构复杂,成本高,若将其应用于临床,会提高患者的治病成本。
技术实现思路
为解决现有技术中输液管内空气不易排出、而现有排气装置结构复杂、成本高的问题,本技术提供一种自动排气的输液针座。本技术的目的是以下述方式实现的:一种自动排气的输液针座,包括输液外管,输液外管上段的空腔内套装有输液内管,输液内管的上端沿输液外管伸出,输液内管的伸出端连接针头,输液内管的下端固接在输液外管上,输液内管的下端连接自排气组件,自排气组件由侧壁和底端组成,自排气组件的内腔与输液内管的内腔相通,自排气组件侧壁的下段开有通孔,自排气组件的侧壁与输液外管的内壁之间留有空隙。所述自排气组件为圆柱状。所述输液外管与输液内管为一体成型。所述输液内管与自排气组件为一体成型。有益效果:本技术设计在输液内管底端固装自排气组件,自排气组件侧壁的下段开有通孔,使得无论针座处于竖直方 ...
