Abstract

一种穿刺深度后置调节的采血笔，包括笔帽（1）、帽座（2）、射杆（6）以及外壳（17），采血笔上设有深度调节外套（8）和深度调节中套（9），射杆（6）位于深度调节中套（9）内，深度调节外套（8）套装于深度调节中套（9）外；深度调节外套（8）相对于外壳（17）在周向转动连接，同时在轴向定位连接，深度调节外套（8）与外壳（17）之间设有旋转定位机构；深度调节中套（9）相对于外壳（17）在周向定位连接，同时在轴向滑动连接，深度调节中套（9）与深度调节外套（8）之间设有旋转移动机构，深度调节中套（9）上对应射杆（6）的主动撞击面（7）设有被动撞击面（13）；深度调节外套（8）上设有外露在采血笔中后部外侧的手动调节圈（10），转动手动调节圈（10）带动深度调节中套（9）轴向移动，从而改变针尖穿刺深度。该穿刺深度后置调节的采血笔将穿刺深度调节机构从采血笔头部分离出来，并转移到采血笔的中后部，解决了安装采血针干扰穿刺深度的问题。
