我们开发了一种低温等离子体装置作为止血手术装置。需要一种分析低温血浆特性与血液成分之间关系的定量测量方法和系统来评估血浆设备的性能和安全性。在之前的研究中，我们发现低温血浆会溶血红细胞，释放的血红蛋白有助于血栓形成；当低温等离子体产生的电流值超过一定阈值时，就会发生低温等离子体溶血。在当前的研究中，我们使用改进的测量系统通过实验检查了血红蛋白浓度和电流值之间的相关性。我们提出了一种通过调节等离子体电流值来控制溶血效应的方法。
We have developed a low‐temperature plasma apparatus as a surgical device for haemostasis. A quantitative measurement method and system that analyses the relationship between the properties of low‐temperature plasma and blood components are necessary to evaluate the performance and safety of plasma apparatuses. In a previous study, we revealed that low‐temperature plasma haemolyses erythrocytes, and the released haemoglobin contribute to clot formation; haemolysis by low‐temperature plasma occurs when the value of the current originating from low‐temperature plasma exceeds a certain threshold. In the current study, we examined the correlation between the haemoglobin concentration and the electric current value through experiments using our improved measurement system. We propose a method to control the haemolysis effect by adjusting the plasma current value.
