随着B型超声诊断的广泛应用,对B型超声耦合剂的需求也越来越多。不少医院采用以液体石蜡加不同乳化剂制成的乳剂,因其油性大,不易清洗,临床使用不够满意。1985年,我们根据文献报道,配制了一种亲水性耦合剂,一年多来,经过我院和其他几家医院8000多例临床使用,证明其电视显像和摄片图像清晰,效果良好,现介绍如下:处方:羧甲基纤维钠(600～1400厘泊)20g、丙三醇200ml、苯甲酸钠5g、1%美兰溶液适量、蒸馏水加至1000ml。制法:取丙三醇置于烧杯中,加入羧甲基纤维素钠并不断搅拌,至全部被丙三醇湿润为止。另将苯甲酸钠溶于约700ml 蒸馏水
With the widespread use of B-mode ultrasound, there is an increasing demand for B-type ultrasound coupling agents. Many hospitals to use liquid paraffin emulsion made of different emulsifiers, because of its oily, difficult to clean, not satisfactory clinical use. In 1985, according to the literature, we prepared a hydrophilic coupling agent, over the past year, more than 8,000 cases of clinical use in our hospital and several other hospitals to prove that its television imaging and radiographic images clear and good results , Are described below: Prescription: sodium carboxymethyl cellulose (600 ~ 1400 cps) 20g, glycerol 200ml, sodium benzoate 5g, 1% Meilan solution amount, distilled water added to 1000ml. System of law: Glycerol was placed in a beaker, adding sodium carboxymethyl cellulose and stirring constantly, until all the glycerin soaked. Another sodium benzoate dissolved in about 700ml of distilled water
