WG—C型耦合剂是一种新型的医用超声耦剂。溶于水,不含表面活性剂,呈中性,不滴流,无毒性,对皮肤无刺激性,对探头无侵蚀作用。测量了藕合剂的衰减和声速。对它的物理化学性能作了测试和评价。推算得的声阻抗与人体的匹配较好,能得到清晰的图像,性能与国外同类产品相当。本文简单介绍了一些性能的测试方法。 WG-C coupling agent is a new type of medical ultrasound coupling agent. Dissolved in water, non-surfactant, neutral, non-trickle, non-toxic, non-irritating to the skin, no erosion of the probe. The decay and velocity of the coupling agent were measured. Its physical and chemical properties have been tested and evaluated. Calculated acoustic impedance and human body better match, can get a clear image, performance and similar foreign products. This article briefly describes some of the performance testing methods.
