Abstract

一种侧孔针头，属于医疗器械领域。本实用新型侧孔针头就侧孔形态进行改良，将针头之侧孔设计为弧形，且此侧孔远离针尖端之弧形曲度与其靠近针尖端之弧形曲度不对称。此结构设计更符合流体力学，可使药液的流动顺畅、注射精准，且有助于保护大颗粒分子之形态完整。

Description

侧孔针头
技术领域
本实用新型侧孔针头属于医疗器械领域。
背景技术
现有侧孔针头其侧孔多呈矩形，或仅为一圆点开孔。当使用于整形美容，如：注射脂肪球时，容易挤压、拉扯大颗粒分子，导致分子受破坏或变形，进而影响整形效果。
发明内容
为保证及提升整形效果，本实用新型侧孔针头就侧孔形态进行改良，使用时可防止大颗粒分子受到挤压、拉扯等物理性破坏，同时有助于精准注射。本实用新型之侧孔呈弧形，且此侧孔远离针尖端之弧形曲度与其靠近针尖端之弧形曲度不对称。此结构设计更符合流体力学，可使药液的流动顺畅、注射精准，且有助于保护大颗粒分子之形态完整。
附图说明
图1为本实用新型侧孔针头示意图。
图2为本实用新型侧孔针头侧孔形态说明。
图中，1：侧孔；1’：侧孔靠近针尖端；1”：侧孔远离针尖端；2：针管；3：侧孔对称线。
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，本实用新型侧孔针头之侧孔(1)呈弧形，且此侧孔远离针尖端(1”)之弧形曲度较其靠近针尖端(1’)之弧形曲度为大。此结构设计更符合流体力学，可使药液推进时流动顺畅、注射精准，且有助于保护大颗粒分子之形态完整，不受挤压、拉扯，或卡于侧孔。

Claims (3)

1.一种侧孔针头，包括针管和开口，其特征在于：此侧孔针头开口位于针管侧边，呈弧形，且其远离针尖端之弧形曲度与其靠近针尖端之弧形曲度不对称。
2.根据权利要求1所述的侧孔针头，其特征在于：此弧形侧孔远离针尖端之弧形曲度较其靠近针尖端之弧形曲度为大。
3.根据权利要求1所述的侧孔针头，其特征在于：此侧孔位于针管前端。
