一种便携型电磁感应式凝血测试传感器

近年来,随着心血管疾病增多,需要对患者测凝血状况。为了减轻复杂程序给医疗保健者带来的负担并实现对患者的病情进行连续动态、定性和定量的观察,本文设计了一种基于电磁感应式凝血测试便携式传感器。根据法拉第电磁感应定律和诺曼公式,设计电磁感应线圈,利用电磁感应法驱动血液中的机械探头进行周期性振动。通过与市面上存在传感器的进行相关性对比,其相关性达到了0.996,表明传感器可以满足临床上精度的要求,具有相对稳定的工作特性,达到了传感器结构设计的目的,具有结构简单,成本低,高灵敏、抗疲劳等优点,具有巨大经济效益与市场竞争力。

In recent years,with the increase of cardiovascular diseases,it is necessary to measure coagulation status in patients.In order to reduce the burden of complex procedures on health care providers and achieve continuous dynamic,qualitative and quantitative observation of the patient's condition,this article designed a portable sensor based on electromagnetic induction coagulation test.According to Faraday's law of electromagnetic induction and Norman's formula,an electromagnetic induction coil is designed and a mechanical probe in blood is driven by electromagnetic induction method to perform periodic vibration.By correlating with the presence of sensors on the market,the correlation reached 0.996,indicating that the sensor can meet the requirements of clinical precision,has relatively stable working characteristics,has achieved the purpose of sensor structural design,has a simple structure,and has a low cost.,High sensitivity,anti-fatigue and other advantages,with huge economic benefits and market competitiveness.
