摘　　要：对于近中性的医疗器械产品浸提液进行酸碱度pH检测时,总会出现示值漂移、响应缓慢等一系列的现象,这种现象对于医疗器械产品酸碱度pH的检测会带来一定程度上的偏差。通过分析产生这些现象的原因对这些现象采取相对应的处理方法,对实际生产和监督检测关于酸碱度pH的判定具有一定的参考意义。When testing the pH value of the extraction solution of near neutral medical device products,a series of phenomena such as indication drift and slow response will always appear,this phenomenon will bring some deviation to the pH value detection of the pH value of the medical device product.In this paper,the causes of these phenomena are analyzed,and the corresponding treatment methods are adopted,which have certain reference significance to the determination of pH value of acid-base degree in actual production and monitoring.
