为了解决注射配液在无菌、无尘和自动化的条件下进行，经实验研制一次性双通分流器，配套应用于静脉肌注净化配液工作台内，经临床应用，方便、省时，达到无菌、无尘要求。报告如下。1材料及制作1．1材料及规格：①PVC负压管3～4mm，吸液负压管长25cm，抽药负压管长10cm；②塑?
In order to solve the injection dosing under sterile, dust-free and automated conditions, a one-time double-pass diverter was developed experimentally to be used in an intravenous intramuscular injection purification liquid table, which is clinically convenient and time-saving. To achieve aseptic, dust-free requirements. The report is as follows. 1 Materials and production 1.1 Materials and Specifications: 1 PVC negative pressure tube 3 ~ 4mm, suction negative pressure tube length 25cm, pumping negative pressure tube length 10cm; 2 plastic?
