Abstract

一种静脉穿刺留置针。属医疗器械领域。由弧形金属针芯1和软套管2构成,软套管2末端用海绵塞9堵塞,弧形金属针芯1末端固定在塑料针柄8上,弧形金属针芯1通过海绵塞9进入软套管2后,其针尖斜面刚露出套管,侧支管3与软套管2相连通,侧支分管3与三通管4相连通,侧分管上有夹片7,在三通管4两端出口处套有硅胶套盖6,留置针上设有定位片5。其优点是:金属针芯呈弧形,针芯弧形段能顺利穿入、拔出软套管,提供一种能有效避免穿破血管后壁并能方便留置的多通道的静脉穿刺留置针。

Description

新型静脉穿刺留置针
技术领域
本实用新型涉及一种医疗器械。更具体的讲是一种带多路通道的弧形静脉穿刺留置针。
背景技术
专利号为200920092268.7的实用新型专利,提供了一种弧形静脉穿刺留置针,但此种穿刺针是单通道,无加药口,不方便留置。
发明内容
本实用新型的目的是提供一种能有效避免穿破血管后壁并能方便留置的多通道的静脉穿刺留置针。
它的技术方案为:金属针芯呈弧形,金属针芯弧形段能顺利穿入、拔出软套管,软套管侧面连接侧分支管,侧分支管连接三通管。
该实用新型的优点是:金属针芯呈弧形,针芯弧形段能顺利穿入、拔出软套管,静脉留置针软套管上设置了三通管加药方便,即可输液,又可加药,使用方便。
附图说明
该附图为本实用新型结构示意图。附图中:1、金属针芯,2、软套管,3、侧分支管,4、三通管,5、定位片,6、硅胶套盖,7、夹片8、针柄9、海绵塞
具体实施方式
软套管2末端用海绵塞9堵塞,弧形金属针芯1末端固定在塑 料针柄8上,弧形金属针芯1通过海绵塞9进入软套管2后,其针尖斜面刚露出套管,侧支管3与软套管2相连通,侧支分管3与三通管4相连通,侧分管上有夹片7,三通管4两端口出套有硅胶套盖6,留置针上设有定位片5;穿刺成功后,顺弧度将软套管沿金属针芯送入静脉,软套管进入静脉后,恢复其直形;拔出弧形金属针芯,将定位片固定在患者皮肤上,通过软套管和三通管多路通道可同时向患者输液、推药和输血等,不输血不输液的情况下,用夹片夹闭三通管通道。

Claims (1)
