Abstract

本实用新型涉及到一种医用注射针头。本实用 新型所述的多孔静脉/麻醉针头由针头接口1和针 干2组成,针干2侧壁有微孔3,所述的微孔3集中 在针干2离针尖三分之一范围以内。本实用新型所 述的针头,由于侧壁上的微孔集中在针头末梢,主要 用于静脉和麻醉注射,当用于静脉注射时,所有侧孔 均能在血管内,抽血和注射速度加快,不易被血凝块 堵塞或外漏,在抢救病人时尤能起到快速给药之效 果。当用于麻醉时,具有局麻时多层次注射给药,具 有药物分布广、吸收快等优点。

Description

本实用新型涉及到一种医用注射针头。
目前公开使用的注射针头,仅有一孔,注射时速度慢,并容易造成局部肌肉结块,中国专利申请CN86200001公开了一种“多孔注射针头”,其特征是在注射针头管壁上打几个微侧孔。中国专利申请CN2055388(申请号(89205034)公开了一种“多孔多向型注射针头”,其特征是在注射器针头的前端侧壁上开有若干小孔,它们与针头针尖的“马蹄形”针孔相通。上述两份专利申请的目的都是使注射药液能从不同孔洞、多方位地注入肌肉,减少单一部位的压力,减少疼痛,上述申请的主要目的是用于肌肉注射,由于针头上的小孔间有一定距离,不能用于静脉或麻碎注射。
本实用新型的目的旨在克服现有技术的不足,提供一种专用于静脉和麻醉注射的多孔针头。
本实用新型所述的多孔静脉/麻醉针头由针头接口和针干组成,针干侧壁有微孔,所述的微孔集中在针干离针尖三分之一范围以内。
本实用新型所述的针头,由于侧壁上的微孔集中在针头末梢,主要用于静脉和麻醉注射,当用于静脉注射时,微孔最好集中在离针尖四分之一范围内,以保证静脉穿刺时,所有侧孔均能在血管内,抽血和注射速度加快,不易被血凝块堵塞或外漏,在抢救病人时尤能起到快速给药之效果。当用于麻醉时,侧孔分布可在离针尖三分之一范围内,具有局麻时多层次注射给药,使药物分布广、吸收快,具有很快达到麻醉要求等优点,可大大降低麻醉时注药次数,节省时间,尤其适应于战伤、各种外伤抢救。
下面结合附图对本实用新型做进一步的说明。
附图为本实用新型示意图。
