近年来心脏和血管的X造影检查,有很大的发展,造影检查不仅从血管的解剖和形态方面来诊断疾病,而且还通过对血流动态功能方面的观察,加深对疾病的认识和了介,因此促进了造影设备的发展,在X线主机、快速换片机、影象强增、电视录象技术等方面,都有很大进展。这里简单介绍一下用于心血管造影的高压注射器发展动向。50年代出现一些使用压缩气体为动力的高压注射器。压缩的二氧化碳气体,经分压表、开关、中间工作气缸等机构推动注射器活塞芯。造影剂的流量(即毫升/秒)由调节
In recent years, X-ray examination of the heart and blood vessels has been greatly developed. Contrast-enhanced imaging not only diagnoses the disease from the anatomy and morphology of blood vessels, but also deepens the understanding of the disease through the observation of the dynamic function of the bloodstream , Thus promoting the development of imaging equipment in the X-ray host, rapid changer, image enhancement, video recording technology, have made great progress. Here is a brief introduction to the development of high pressure syringes for cardiovascular angiography. In the 1950s there were some high-pressure syringes powered by compressed gas. Compressed carbon dioxide gas, the partial pressure gauge, switch, intermediate work cylinder and other agencies to promote syringe plunger. Contrast media flow (ie ml / sec) is adjusted
