阅读说明：本技术 样本分析装置及吸液控制方法 (Sample analyzer and liquid suction control method ) 是由 杜贤算 胡力坚 于 2019-05-20 设计创作，主要内容包括：一种样本分析装置及吸液控制方法,通过设置检测单元(40),在吸液件(303)向吸液位移动时,该检测单元(40)能够检测吸液件(303)的移动轨迹上是否有遮挡物。检测单元(40)将检测信号反馈至控制单元,控制单元根据接收到的检测信号来控制吸液件(303)的运动状态,例如,如果控制单元收到表示有遮挡物的信号时,可控制吸液件(303)减速、停止或回退等,以避免吸液件(303)与遮挡物碰撞,尤其是遮挡物为人手时,可避免吸液件(303)刺破人手,同时也避免破坏吸液件(303)。(A sample analyzer and a liquid suction control method are provided with a detection unit (40), and when a liquid suction member (303) moves to a liquid suction position, the detection unit (40) can detect whether a blocking object exists on a movement track of the liquid suction member (303). The detection unit (40) feeds back the detection signal to the control unit, and the control unit controls the motion state of the liquid absorbing piece (303) according to the received detection signal, for example, if the control unit receives a signal indicating that a shelter is present, the control unit can control the liquid absorbing piece (303) to decelerate, stop or retreat, and the like, so as to avoid the collision of the liquid absorbing piece (303) with the shelter, especially when the shelter is a human hand, the liquid absorbing piece (303) can be prevented from being punctured by the human hand, and meanwhile, the damage to the liquid absorbing piece (303) can be avoided.)
