穿刺器具
摘要：
本发明提供一种穿刺器具(10)，其为接受螺旋弹簧(31a)的推动力，向前端侧发射穿刺针(21)，并利用返回弹簧(31b)的推动力使已发射的穿刺针(21)后退的穿刺器具(10)，在发射穿刺针(21)时，作为保持包括穿刺针(21)的刺血针(20)的刺血针保持具(32)的一部分的碰撞部(32b)和作为撞止部件(38)的一部分的被碰撞部(38a)碰撞，使撞止部件(38)发生弹性形变。由于撞止部件(38)的弹性形变，撞止部件(38)的抵接部(38b)向碰撞部(32b)的方向移动，与碰撞部(32b)接触，削弱刺血针保持具(32)后退的态势。
摘要（英）：

A lancet device (10) for ejecting a puncture needle (21) to the forward end side by biasing force of a coil spring (31a) and causing the ejected puncture needle (21) to retreat by biasing force of a return spring (31b). When the puncture needle (21) is ejected, a colliding section (32b) and a collision taking section (38a) are caused to collide with each other, elastically deforming an abutting stopping member (38), where the colliding section (32b) is a part of a lancet holder (32) for holding a lancet (20) including the puncture needle (21) and the collision taking section (38a) is a part of the abutting stopping member (38). The elastic deformation of the abutting stopping member (38) causes a contact section (38b) of the abutting stopping member (38) to move toward and be in contact with the colliding section (32b), and this damps the momentum of the retreating lancet holder (32).
