Abstract
本实用新型提供了一种五棱刃口注射针，采用现
有注射针制造用自动开刃磨床，所制造的注射针，针
尖呈五棱形刃口，注射针尖顶端两刃口呈对称立体
状，针尖锋利度比原有三棱刃口注射针提高，注射时
可减少肌肉反弹阻力，进针快，大大减轻患者痛感。
Description
本实用新型涉及一种五棱刃口注射针，属医疗器材领域。
目前在医疗保健注射各种药液等时所用的注射针，其针尖均为平面三棱刃口，在制造时均采用传统的先刃磨平面，一般为12°倾角，然后用相同的角度滚动针管，倒左、右两面刃角，形成平面三棱刃口。采用上述注射针给病人作肌肉、皮内等注射时，有较强的痛感。
为克服上述注射针的缺点，本实用新型的目的在于提供一种针尖更为锋利，进针容易，能减少注射时痛感的五棱刃口注射针。
本实用新型采用注射针制造用开刃磨床，当刃磨注射针第一倾角完成后，通过电控换向阀和气动元件，使针管变位并自动刃磨第二倾角的左、右两侧，然后再次自动变位，刃磨第三倾角的左右二侧，从而刃磨出尖端呈对称立体状锋刃，形成五棱刃口注射针。由于五棱刃口注射针针尖比传统三棱刃口注射针锋利度提高，在注射时针尖进入肌肉和皮下组织时，可产生分层分离肌肉的作用，减少肌体的反弹阻力，可加快进针时间，大大减轻了患者痛感。
下面结合附图和实施例，对本实用新型作进一步详细的说明。
附图：五棱刃口注射针针尖示意图
本实施例采用普通注射针制造用开刃磨床，夹具通过电控换向阀和气动元件控制，自动变换两种角度。首先将调角主板调节倾角为11°－17°，然后将排列的不锈钢针管夹住，刃磨第一倾角完成后（附图（1））通过电控换向阀和气动元件，推动夹板向前倾斜3°－6°，再使针管变位，并自动刃磨第二倾角的左、右二侧（附图（2）、（3）），然后再次自动变位1°－3°，刃磨第三倾角的左右两侧（附图（4）、（5）），从而刃磨出五棱刃口注射针，针尖顶端两棱呈对称立体状（图1，（4），（5））。
