Abstract

一种静脉输液注射针包括内针4与外针2、手柄1、弹簧3,内针手柄5。外针2与手柄1之间由弹簧3连接,呈弹性滑动配合。本实用新型的优点在于当护士在穿刺血管时,外针1与皮肤接触产生压力,手柄1发生位移,位移停止,外针2刺破皮肤进入血管。由于血管前方阻力减小,外针2弹出,护士通过肉眼观察弹簧3长度发生变化可以判断外针2进入血管。通过内针手柄5把内针4向前推进血管,完成穿刺。

Description

静脉输液注射针
技术领域
本发明涉及一种静脉输液注射针 
背景技术
静脉输液是医院临床抢救病人和治疗病人的重要措施之一,目前最常用的一次性静脉输液注射针是采用将输液管套接在管状注射针上,使用时将针头扎进病人血管,药物通过输液管及输液针进入血管。但这种一次性输液静脉输液注射针有以下不足:一、输液对护士业务水平要求高,对针头是否刺入血管很难把握。二、输液过程,病人活动受限,针尖容易刺穿血管造成滚针现象。以上问题,到目前为止没有得以很好地解决。 
发明内容
本实用新型为克服以上不足。提出不会造成滚针,并可以凭肉眼判断静脉输液注射针针头是否进入血管、刺针是否完成的静脉输液注射针。 
为实现上述目的,本实用新型采用了以下方案: 
方案1、一种静脉输液注射针,手柄与注射针之间以弹簧连接产生弹性伸缩,当针尖接触皮肤时,手柄前移,针尖压力加大,刺入皮肤,进入血管,压力减小,注射针向前弹出。当护士看到弹簧长度发生变化,知道刺针完成。 
方案2、静脉输液注射针,注射针与手柄之间以弹簧连接,注射针为套管针,外针为尖针,内针为平头针,当注射针针尖与皮肤接触时,手柄前移,压力加大,刺入皮肤,进入血管,血管前方压力减小,注射针弹出。当护士看到注射针弹出,说明外针刺入血管,护士把内针向前推进血管,刺针完成。 
附图说明:
图1、静脉输液注射针弹性伸缩针结构示意图 
图2、静脉输液注射针套管针结构示意图 
具体实施方式
下面通过具体的实施方式结合附图,对实用新型做进一步详细说明。 
如图1所示,静脉输液注射针包括手柄1和注射针2由弹簧3连接,呈弹性伸缩滑动配合。当注射针2与皮肤接触受力,手柄1前移,弹簧3压缩产生压力,当注射针2刺破血管,进入血管,由于血管前方阻力减小,静脉针2弹出,护士看到弹簧3伸展,判断刺针完成。 
如图2所示,静脉输液注射针包括手柄1,静脉针2,弹簧3,内针4,手柄5组成。当静脉针2与皮肤接触受力,手柄1前移,弹簧3压缩产生压力。当静脉针2刺破血管,由于血管前方阻力减小,静脉针2弹出。护士看到弹簧3伸展,护士推动手柄5,内针4进入血管,刺针完成。 
以上内容是结合具体的优选方案、实施方式,对实用新型做的近一步详细说明。这里弹簧泛指产生弹力材料,不能认定本实用新型的具体实施只局限于这些说明,对于本实用新型不脱离本实用型新构思的前提下,还可以做出若干简单推演或替换,都视为属于本实用新型的保护范围。
