| 摘 要： | 为了使柯氏法测量的血压值结果进行放大,便于学生对血压值做出正确的判断。作者提取柯氏法血压时的振动信号,利用医学换能器把这种信号转换为电信号,再通过放大电路,把电信号进行放大。再利用换能器把这种电信号转换为声音信号,并把声音信号进行放大。 |
| 关 键 词： | 柯氏法 血压 信号放大 |

| Abstract: | To amplify blood pressure results of Korotkoff’s method so as to enable students to make a correct judgment of blood pressure values,we extracted the vibration signals of blood pressure measured with Korotkoff’s method,converted them with the medical transducer into electrical signals,which were then amplified with the amplifying circuit.This type of electrical signals was converted with the transducer into sound signals,which were amplified. |
| Keywords: | Korotkoff’s method blood pressure signal amplification |
