测量血压,不仅要求医务人员具备熟练而敏捷的操作技术,而且必须要有一个功能良好的血压计。据临床工作者反映,目前使用的血压计在测血压时不方便,主要存在以下问题:—是操作较繁琐,测一次血压必须两次方向相反地旋转控制臂袖压力的针型阀旋钮;二是针型阀关闭过紧时往往单手难以旋开旋钮;三是针型阀容易磨损,当针型阀关闭不严时,不能使臂袖压力上升或稳压。后两种情况都明显地影响着血压的测定。因此,要求有一种新型的压力控制器,使测血压时既方便又可靠。压力控制器就是根据临床要
Measuring blood pressure requires not only medical personnel skilled and agile operating techniques, but also a functional sphygmomanometer. According to clinical workers reflect the current use of sphygmomanometer blood pressure measurement inconvenient, the main problems are as follows: - is more complicated operation, a measure of blood pressure must reverse the direction of the control arm sleeve needle valve knob; It is difficult to unscrew the knob with one hand when the needle valve is closed too tightly. Third, the needle valve is easy to wear. When the needle valve is not closed properly, the pressure on the arm sleeve can not be increased or regulated. The latter two cases significantly affect the determination of blood pressure. Therefore, there is a need for a new type of pressure controller that is both convenient and reliable for blood pressure measurement. The pressure controller is based on clinical requirements
