传统的溶药法是在暴露的情况下 ,反复穿刺瓶塞完成的 ,不但增加了橡皮栓子异物和药物污染机会 ,且费时费力。我们根据帕斯卡定律 ,研制成一种密闭式溶药器 ,经临床实践 ,避免了传统溶药法的种种弊病 ,效果满意 ,现介绍如下。1　材料及制作本溶药器用聚氯乙烯及不锈钢材料制成。 The traditional method of dissolving drugs is to repeatedly pierce the stoppers in the case of exposure, which not only increases the chance of rubber embolism foreign bodies and drug contamination, but also takes time and effort. Based on Pascal’s law, we developed a closed type drug-dissolving device. Through clinical practice, we have avoided the various drawbacks of the traditional drug-dissolving method with satisfactory results. We now introduce the following. 1 Materials and production This drug dissolver is made of polyvinyl chloride and stainless steel.
