【技术实现步骤摘要】
一种注射器
本技术属于医用注射器结构
,更详细地说涉及一种既能够限定针头刺入深度又能控制刺入位置的新型注射器。
技术介绍
现有的注射器为病人注射药品时,时常会出现针头刺入人体的深度具有不可控性,而造成刺入深度过浅不能注射进去,或者刺入深度过深对病人的组织细胞造成伤害;另外,现有技术中的注射器还存在着在注射药品之前需要对病人注射部位的确定,确定后还需要使用酒精棉擦拭,过程多,控制精度不高,故对护士的熟练度要求就相对高。
技术实现思路
本技术的目的在于提供一种注射器,该注射器可限定针头刺入病人皮肤的深度,而且还可以对刺入的位置进行定位。为实现上述目的,本技术提供如下技术方案:一种注射器,包括内管和外管;所述外管的一端为开口,另一端具有锥形头,在所述锥形头的端部连接有一个可调节长度的伸缩管,所述伸缩管远离所述外管的端部连接有吸盘,在所述吸盘的内侧面上粘接有棉球,位于所述棉球以外的所述吸盘内侧上设有双面胶,且所述伸缩管内还设置有一个毛细封片;所述内管设置在所述外管内,且所述内管的一端为开口,另一端具有锥形头,所述内管的锥形头上连接有针头,所述内管的外侧距所述针头 ...
