1.概述在利用数字技术显示收缩压或舒张压信号时,大多数情况下都不希望那种随着心搏而变化的数值也显示出来,因为这种不稳定的显示就连一个血压本来平稳的病人,其血压监测数字也会不停地闪动,以致读数难以阅读。为了克服这一障碍,设计出了一种电路,它对所测参数的显示很稳定,避免了心搏带来的血压量值微小改变的影响,但保持了即时反映真正血压变化的能力。这个电路被用作信号的辅助性信息处理装置,这些信号来自摸拟性的收缩/舒张血压分隔器。
1. Overview In the digital display of systolic or diastolic blood pressure signals, in most cases do not want that value changes with the heart rate is also displayed, because this unstable display even a blood pressure was stable Of the patients whose blood pressure monitoring figures are constantly flashing so that readings are hard to read. To overcome this obstacle, a circuit was designed which showed a very stable display of the measured parameters, avoiding the effects of small changes in blood pressure values caused by heartbeat but retaining the ability to immediately reflect real blood pressure changes. This circuit is used as an auxiliary information processing device for signals from the contractile / diastolic blood pressure divider.
