乌尔姆Ulrich医疗技术公司研制的用于CT的新型造影剂注射器在乌尔姆大学放射学临床中进行了动物试验和临床试用。这种注射器CT-Injektor XD 5500(图1)为电动的并通过微处理器进行控制和监视,适合于所有商用造影剂的机械注射。注射器可无级选择注射速度,从0.1ml/s到10ml/s。注射速度和注射容量可用程序控制,也可根据器官情况用按钮控制。注射器有一组蓄电池,最多用于注射三瓶造影剂,每瓶250ml。通过蓄电池被选定的造影剂量即可自动排出。使用这种方法可对一定数量的病人进行造影剂注射,无需注射后补充。注射泵有一系列安全设备,其中的电子 Newer contrast media syringes for CT developed by Ulrich Medical Technology in Ulm have been subjected to animal testing and clinical trials in radiology clinics at Ulm University. The Syringe CT-Injektor XD 5500 (Figure 1) is motorized and microprocessor controlled for monitoring and monitoring and is suitable for mechanical injections of all commercially available contrast media. The syringe can be infinitely selected injection speed, from 0.1ml / s to 10ml / s. Injection speed and injection capacity can be programmed, but also according to the organ situation with the button control. Syringe has a battery, up to three bottles of injection contrast agent, 250ml bottle. Through the battery is selected the amount of contrast can be automatically discharged. Using this method, a given number of patients can be injected with contrast media without the need for injection. Syringe pumps have a series of safety devices, of which the electronics
