德国TECOCoatron Ⅳ-plus血凝仪,为半自动四通道血凝仪,在基层医院普遍使用。仪器的温度调节系统是确保检验质量的关键,温度的轻微改变会直接影响检验结果的准确性。本院应用该仪器已5年多,近期发生2次温度自动调节失控,我们根据仪器的原理,利用在日常工作中积累的经验,成功地进行了检修,现将检修方法介绍如下。 German TECOCoatron IV-plus blood coagulation apparatus is a semi-automatic four-channel coagulation apparatus and is commonly used in primary hospitals. The temperature regulation system of the instrument is the key to ensure the quality of the test. A slight change in temperature will directly affect the accuracy of the test results. The instrument has been used in this hospital for more than five years, and two times of recent automatic temperature regulation has been out of control. According to the principle of the instrument, we have used the experience accumulated in daily work to successfully perform maintenance. Now we introduce the method of repair as follows.
