The invention relates to a telescopic Push-hand device for test-tube stand, which belongs to the technical field of medical detection device. The device comprises a support chamber, Push-hand assembly and push-board. The support chamber is a hollow container with side opening. The Push-hand assembly is located in the support chamber, and the push-board is connected with the Push-hand assembly. The Push-hand assembly includes a step motor, the output shaft of the step-motor is connected with the lead screw through a coupling, and the lead screw is arranged on the support chamber. There are two slider nuts. The rotation of the screw drives the slider nut to move along the screw. The two slider nuts have the opposite rotation direction and the same pitch. The two slider nuts are connected to one end of the active connecting rod, the two active connecting rods are connected by pins between the two ends, and the other end of the active connecting rod is connected with the push plate. Stepping motor drives the screw to rotate, and two slider nuts move in a straight line, which drives the connecting rod to rotate in parallel or in separate phases, thus driving the push plate to move. It can push the test tube rack equipped with detected blood components from the inner conveying track to the outer return trajectory at one time.

一种伸缩式试管架推手装置
本专利技术涉及一种伸缩式试管架推手装置,属于医疗检测装置
技术介绍
目前,临床医疗检验单机操作检验压力大、效率低,故而全自动凝血流水线被广泛采用,可一站式解决血凝检测问题。其问题在于,所需检测的血液成分在全自动凝血流水线某个仪器样本臂完成检测,并且不需要再进行下一检测时,不能同试管架一次性从内侧的运送轨道被推送至外侧的回程轨道。现有的试管架推手只能将试管架推至内侧运送轨道,若试图推至外侧轨道存在行程不足、机构干涉等问题,降低检测效率。因此急需要设计一种可伸缩式新型试管架推手来解决此问题。公开号为“CN108535503A”的中国专利,记载了全自动凝血分析仪及使用方法,该专利简述为:全自动凝血分析仪包括样本模块、试剂位模块、抓手模块和进杯模块等,抓手模块位于主空腔内,抓手将加好样本的测试被抓取至温育区,温育一定时间后,再由抓手抓取至磁珠检测区或光学检测区进行检测。该方法虽然能够实现测试杯的抓取和释放,但是其体积大,尤其在空间受限的全自动凝血分析仪上,容易造成测试杯转移困难,测试效率受到限制。公开号为“CN108717113A”的中 ...
