4、根据权利要求 1所述的一种血肿清除器， 其特征在于： 在血肿清除器启动时， 首先由中央 控制器通过一、 二号计量传感器同时获取一、 二号容器内工作液的初始计量值， 分别设定为 a0和 b0， 并控制一号泵和二号泵开始运行； 随后由中央控制器通过一、 二号计量传感器实时 获取一、 二号容器内工作液的计量值， 分别设定为 a1和 b1， 并与各自对应的上述初始计量 值比较得到变化值， 分别设定为 Δ a和 Δ b; 中央控制器通过比较 Δ a和 Δ b值， 对一号泵和 二号泵在单位时间内的泵液量进行相应调整。 4. A hematoma eliminator according to claim 1, characterized in that: when the hematoma eliminator is started, the central controller first simultaneously obtains the initial values of the working fluid in the first and second containers through the first and second measuring sensors. The measurement values are set to a0 and b0 respectively, and the No. 1 and No. 2 pumps are controlled to start running; then the central controller obtains the measurement values of the working fluid in the No. 1 and No. 2 containers in real time through the No. 1 and No. 2 measurement sensors, respectively. Set to a1 and b1, and compare with the respective corresponding initial measurement values to obtain the change values, which are set to Δ a and Δ b respectively ; the central controller compares the values of Δ a and Δ b to pump No. 1 and No. 2 The pump liquid volume per unit time is adjusted accordingly.
