摘　　要：深静脉穿刺置管是救治危重症患者的一项常规且基础的操作,是快速纠正休克最有效的途径。传统B超引导下深静脉置管能提高穿刺成功率,但操作过程中需短轴换长轴,更换过程存在新手操作稳定性不足、定位困难等问题,进而导致操作时间过长;若只使用短轴穿刺,无法了解当前穿刺针的位置,可发生穿刺过深误入动脉;针对进针点45°的准确性需要操作者经验非常丰富。针对上述缺点,浙江大学医学院附属杭州市第一人民医院重症医学科医生设计了一种B超穿刺设备,并获得了国家发明专利(ZL 2016 1 0571557.X),该装置由B超探头固定架、滑动刻度板、模拟计算尺、穿刺针、滑动装置组成,通过滑动装置调节针孔通道角度有利于对穿刺目标进行精准定位,优化操作步骤,提高穿刺速度与精准度,有效减少穿刺并发症的发生,保证患者安全,避免不必要的人力物力浪费,减少医护人员工作量,值得临床实践推广应用。Deep venipuncture catheterization is a routine and basic operation in the treatment of critically ill patients,and it is the most effective way to quickly correct the shock.Clinical B-ultrasound guided deep vein catheters can improve the success rate of puncture,but in the process of operation,the short axis needs to be replaced by the long axis.In the replacement process,the stability of the novice is insufficient,the positioning is difficult,and the operation time is too long.If only short axis puncture is used,it is impossible to know whether the current position of the puncture needle,and the puncture may be too deep and stray into the artery.The accuracy of the 45°of the injection point requires a very experienced operator.In view of the above shortcomings,doctors in the department of critical care medicine of Affiliated Hangzhou First People's Hospital,Zhejiang University School of Medicine designed a B-ultrasound puncture equipment,which has obtained the National Invention Patent of China(ZL 201610571557.X).The device is composed of B-ultrasound probe fixing frame,sliding scale plate,simulation slide rule,puncture needle,sliding device.By sliding device the angle of the pinhole channel,it is conducive to the accurate positioning of the puncture target,optimizing the operation procedure,improving the puncture speed and accuracy,effectively reducing the occurrence of puncture complications,ensuring patient safety,reducing unnecessary waste of human and material resources.It can reduce the workload of medical staff and is worthy of clinical practice.
