1978年英国AndrewStephens公司生产了一种快速显示的数字式血压计。该新产品特点是包括由数字压力显示的快速充气和自动对压缩空气以2～3毫米汞柱/搏动平稳速度排气两部分组成,并在收缩压和舒张压时,将数字定位。该计通过金属环抽拉臂带,这样收紧的臂带可确保臂带内的换能器平放在臂的动脉上,不会产生滑动。在测量时,为了避免使换能器(探测器)拾取环境中的噪音,臂带内的专用扩散型空气压力换能器是和
In 1978 Britain AndrewStephens company produced a quick display of digital sphygmomanometer. The new product features quick inflation, displayed by digital pressure, and auto-exhaust of compressed air at 2 to 3 mmHg / stroke at steady-rate exhaust and digitally positions systolic and diastolic pressures. The gauge draws the armband through the metal ring so that the tightened armband ensures that the transducer in the armband rests flat against the artery of the arm without slippage. In the measurement, in order to avoid making the transducer (detector) pick up the noise in the environment, the dedicated diffuser type air pressure transducer in the arm band is
