Description

一种带翼的安全型静脉输液留置针 A tape-type safety winged intravenous infusion catheter

技术领域 FIELD

本实用新型涉及一种一次性医疗器具,尤其涉及医学临床上使用的安全型静脉输液留置针。 The present invention relates to a disposable medical devices, and more particularly to safe use of intravenous infusion of clinical medicine catheter.

背景技术 Background technique

现有的静脉输液留置针一般包括穿刺针和套在穿刺针上的留置套管,是利用留置套管向患者进行静脉输注药液。 Conventional intravenous infusion catheter generally comprises a sleeve and the needle in the indwelling needle cannula, a cannula for indwelling intravenous infusion liquid to a patient. 由于软性的留置套管极具挠性,当留置套管置于静脉中时,留置套管会随静脉同步曲折,使得注射部位仍可自由动作,不会有刺穿静脉之虞。 Since very soft flexible indwelling cannula when the cannula was placed indwelling vein indwelling intravenous cannula sync with winding, so that the operation of the injection site remains free, there will be no danger of puncturing the vein. 因此,静脉输液留置针更具有使用的安全性,并且减少患者使用时的不适感。 Thus, intravenous infusion catheter having more safety of use and reduce patient discomfort during use.

但是,这种静脉输液留置针在穿刺完毕后,穿刺针的屏蔽成为了一大问题。 However, the intravenous infusion catheter after the puncture is completed, the needle shield has become a major problem.

虽然对于某种结构的静脉输液留置针已有了有效的屏蔽方式,例如,在申请号为9812703.2的中国发明专利申请中,提及一种多用途安全自动输液静脉留置针,包括三叉管接头、留置软针、钢针及输液管;三叉管接头其第一、第二接头端轴向对正,第二接头端嵌套橡胶帽套;留置软针嵌套于三叉管接头第一接头端;钢针滑套于套筒中,套筒嵌套于三叉管接头第二接头端,针体轴向穿置留置软针中;输液管串接三叉管接头第三接头端,药液经留置软针注入患者体内。 While the indwelling needle shield has an effective manner for intravenous infusion of a certain structure, for example, in the Chinese invention patent application No. 9812703.2, the reference to a multi-purpose automatic safety intravenous catheter infusion, including trigeminal fittings, soft needle catheter, infusion tube and needle; trigeminal pipe joint having a first, a second connector end axially aligned, the second connector end nest rubber caps; soft needle catheter to a first connector end nest trigeminal fittings; needle sleeve in the sleeve, the second sleeve coupling end trigeminal nested fittings, needle penetration and axially flexible indwelling needle; infusion tube fittings series trigeminal third connection terminal via the liquid retention soft needle into the patient. 将留置软针连同针体刺入患者静脉后,从套筒后侧拉退针体,使针体内缩卡扣于套筒内,可避免针体外露发生刺伤及感染等,且可从容完成注射程序。 The soft needle catheter together with the needle after piercing the patient's vein, the rear sleeve is pulled back from the needle, the needle body in the sleeve snap reduction can avoid the occurrence of puncture needle exposure and infection, and can be completed comfortably injection procedure.

但是,针对临床上通常使用的带翼的静脉输液留置针,仍然没有找到一种有效的避免其针体外露的方法,因而,医护人员在清理或废弃该留置针时容易受针刺伤害而感染疾病。 However, intravenous infusion for a clinically winged indwelling needle commonly used, still have not found an effective method of avoiding that the needle is exposed, and therefore, when the cleaning staff or discarded vulnerable indwelling needle stick injury and infection disease. 尤其被传染病患者(例如:肝炎、爱滋病患者)使用过的穿刺针刺伤,后果不堪设想。 In particular, patients are infectious diseases: use (such as hepatitis, AIDS patients) had a puncture needle stick injuries, the consequences could be disastrous.

因此,对于带翼的静脉输液留置针,人们一直在积极地寻找其穿刺针使用后的有效屏蔽方法,以避免误穿刺等偶然事故的发生。 Thus, for a winged intravenous infusion catheter, it has been actively searching for an effective method of shielding the needle after its use, in order to avoid accidental erroneous puncture accidents.
