【技术实现步骤摘要】
防刺伤针头
本技术涉及护理工具
,尤其涉及防刺伤针头。
技术介绍
胰岛素注射治疗是个长期的过程,一般糖友都会选择在家自行注射。为减少对皮肤的损失和疼痛感,胰岛素针头都较尖细。胰岛素针头尖、细,且不同于一般针体的安装,在摘取胰岛素针头时,在摘取针头时容易划伤操作人员的手,造成锐器伤,增加操作人员感染风险。
技术实现思路
本技术旨在提供防刺伤针头,针头可回缩,使用安全。为达到上述目的,本技术采用的技术方案如下:防刺伤针头,包括针座、针体、针帽、套筒和导液管,所述套筒后端与针座前端固接,所述套筒内轴向设有导向孔,所述导向孔内设有滑块,滑块与导向孔滑动配合;针体后端与滑块前端固接;所述针座上设有通孔A,通孔A和导向孔同轴,通孔A与导向孔内部相通;所述导液管前端穿过通孔A伸进导向孔中与滑块连接,所述滑块内部设有导液通道,所述针体、导液通道、导液管内部相通;所述针体与滑块的长度之和小于导向孔的长度;所述针体、滑块与导液管的长度之和大于导向孔与通孔A的长度之和;所述导向孔内轴向设有用于使滑块向后移动的弹簧A,所述导向孔内壁设有台阶,所述滑块外壁设有弹片,弹片自由端顶在台阶上防止滑块在弹簧A的作用下向后移动;所述套筒上设有用于按压弹片的按压杆,所述套筒侧壁径向设有通孔B,通孔B与弹片相对,按压杆一端伸进通孔B内。进一步的,通孔B内设有弹簧B,弹簧B套设在按压杆,按压杆外壁设有圆台,弹簧B外端与圆台连接。其中,导液管与通孔A滑动配合,导液管外壁与通孔A内壁之间设有密封圈。或者,导液管与针座固接,滑块后端设有通孔C,所述通孔C与导液通道内部相通,导液管前端穿过通孔C伸进导液通道 ...
