使用棉签清洗用过的注射针头,费工费时效率低。我们利用沪产800型离心沉淀器上的串励电机,串接一只100瓦的灯泡,配上一只脚踏开关,制成了简易针头捻洗机,提高工效近十倍。该机线路图见图1。电机二端电压 The use of cotton swabs to clean used needles, laborious and inefficient time-consuming. We use the Shanghai Series 800 Centrifugal Sedimentation precipitator on the machine, a 100-watt series of light bulbs, coupled with a foot switch, made a simple needle twister to improve work efficiency nearly ten times. The circuit diagram shown in Figure 1. Motor voltage at both ends
