笔者依据JJF1259-2010《医用注射泵与输液泵校准规范》对仪器校准的过程中发现,操作中的一些细节会影响校准结果的可靠性,甚至发生误判。下面介绍校准过程中的一些建议,供大家参考。1.注射泵由步进电机及其驱动器、丝杆和支架等构成,具有往复移动的丝杆、螺母,因此也称为丝杆泵。螺母与注射器的活塞相连,注射器里盛放药液。工作时,单片机系统发出控制脉冲使步进电机旋转,而步进电机带动丝杆将旋转运动变成直线运动,推动注
The author based on JJF1259-2010 “medical syringe pump and infusion pump calibration specification” of the instrument calibration process found that some details of the operation will affect the calibration results of the reliability, or even misjudgment. The following describes some of the recommendations in the calibration process for your reference. 1. Syringe pump by the stepper motor and its drives, screw and bracket and other components, with reciprocating screw, nut, it is also known as screw pump. The nut is connected to the plunger of the syringe, and the syringe holds the solution. Work, the microcontroller system to issue control pulses so that the stepper motor rotation, and stepper motor driven screw will rotate into a linear motion, and promote the note
