Abstract

一种安全针头，属于医疗器械领域。本实用新型安全针头就针尖进行改良，将针头之针尖设计为钝状，无锐口、带有斜面，呈类似弹头状之圆滑曲面。使用时可自然避开神经、血管、腺体等皮下组织，降低皮下注射时，因注射针头针尖具锐口而带来的医疗风险。

Description

安全针头
技术领域
本实用新型安全针头属于医疗器械领域。
背景技术
常见的注射针头针尖皆具锐口且开口于针尖位置，使用于皮下注射时，锐利的针尖很可能伤及血管、神经、腺体等皮下组织，导致血管破裂、药液误入血管，甚至造成神经瘫痪等严重后果。特别是在进行整形美容时，若注射玻尿酸、脂肪等较大的分子而药液误入血管，还可能堵塞血管，造成局部组织坏死等等；此类伤害格外难以弥补。
发明内容
为降低皮下注射时，因注射针头针尖具锐口而带来的医疗风险，本实用新型安全针头就针尖进行改良，使用时可自然避开神经、腺体，且避免刺破血管。本实用新型解决其技术问题所采用的技术方案是：将针头之针尖设计为钝状，无锐口、带有斜面，呈类似弹头状之圆滑曲面。钝状、无锐口之针头，可避免针头进入皮下时伤及神经、血管、腺体等皮下组织。针头带有斜面、呈类似弹头状，可减少针管进入皮下的阻力，并有助于操作时之方向控制。针管开口为弧形，位于针管前端侧边，可减小当注射过猛时，药液对组织的冲击。
附图说明
图1为本实用新型正视图。
图2为本实用新型俯视图。

以下结合附图和实施例对本实用新型作进一步说明。
具体实施方式
如图所示，本实用新型安全针头针尖(1)为钝状，呈类似弹头状之圆滑曲面，无锐口、带有二个斜面(2，2’)。各斜面(2，2’)与针管(4)之中心线(5)的夹角为22.5度，使针头呈类似弹头状，可减少针管进入皮下的阻力，并有助于操作时之方向控制。针管开口(3)呈弧形，位于针管(4)前端侧边，可减小注射时药液对组织的冲击。

Claims (5)

1.一种安全针头，包括针管和开口，其特征在于：此安全针头针尖形态为非锐利之钝状、弹头状之圆滑曲面，且此圆滑曲面上加有二个及以上的斜面。
2.根据权利要求1所述的安全针头，其特征在于：各斜面与针管中心线之夹角介于3度至87度。
3.根据权利要求1所述的安全针头，其特征在于：此针头开口位于针管侧边。
4.根据权利要求3所述的安全针头，其特征在于：此开口位于针头前端。
5.根据权利要求4所述的安全针头，其特征在于：此开口呈弧形。
