请参阅图1至图4，本发明提供一种技术方案：低容量血浆置换设备，包括机箱组件1，机箱组件1的内侧设置有离心机部件14，机箱组件1的顶部相对于离心机部件14的一侧设置有药物泵10、抗凝剂泵24和抽血泵11，药物泵10和抽血泵11的一侧均设置有第一空气探测器部件12，机箱组件1的顶部相对于离心机部件14的另一侧设置有线感部件5，且线感部件5的一侧设置有两个第一电磁阀4，机箱组件1的顶部相对于离心机部件14的后方设置有显示屏2，机箱组件1的前表面设置有两个第二空气探测器部件16，且第二空气探测器部件16的上方设置有患者压力检测器部件15，机箱组件1的顶部还设置有倾斜面，倾斜面上设置有第二电磁阀13和秤部件7，秤部件7包括重量传感器和可折叠称重悬臂，可折叠称重悬臂固定在机箱组件1上，重量传感器位于带有可折叠称重悬臂的装置主体内，节省空间，还可以防止在运输和搬运过程中损坏重量传感器。
本实施例中，优选的，药物泵10包括基板101、旋转座102和柔轮103，基板101固定在机箱组件1的顶部，基板101的内侧通过无刷伺服电机转动设置有旋转座102，基板101的下方安装有与无刷伺服电机连接的行星减速机，使得药物泵10的运转非常缓慢，从而致使药液在还输过程中更加的精确，且 旋转座102的顶部转动装设有三个柔轮103，采用多柔轮结构设计，具有流量精度高。
本实施例中，优选的，机箱组件1的顶部相对于显示屏2的两侧分别设置有第一挂杆3和第二挂杆组件9，机箱组件1的两侧表面分别设置有第一侧显示部件6和第二侧显示部件17。
本实施例中，优选的，机箱组件1的一侧表面相对于第一侧显示部件6的底部设置有读卡扫码部件8，读卡扫码部件8使用光学传感器读取一次性包装上的条形码和二维码，然后，可以根据等离子中心的要求对这些信息进行处理，机箱组件1的另一侧表面相对于第二侧显示部件17的底部设置有滴注传感器18，滴注传感器18是通过计算单位时间内检测到的滴注液体容量而计算出液体的实际流速，保证输液速度更加精确可控，输液过程更加安全，保证输注抗凝剂、人血白蛋白和IGIV的速度和精度。
本实施例中，优选的，机箱组件1的前表面设置有前板报警指示器23，且前板报警指示器23处于第二空气探测器部件16的一侧。
本实施例中，优选的，机箱组件1的内部设置有电源部件19、控制盒组件20、后转接模块21和充气部件22，电源部件19和控制盒组件20分别设置在机箱组件1的内部两侧，后转接模块21和充气部件22设置在控制盒组件20的一侧。
本发明的工作原理及使用流程：该低容量血浆置换设备在使用时，先将抽血泵11连接输血管从患者身体采集血液，在采集过程中抗凝剂泵24会将抗凝剂输入输血管，保证血液在抽取过程中不会凝固，患者血液会在抽血泵11的抽取作用下抽入离心机部件14的内部，完成血液中血浆和红细胞的分离，当采集的血浆量达到目标值后，将抽血泵11反向启动，将去除血浆后的血细胞在不经过离心机部件14的情况下直接还输至患者体内，同时在还输过程中，启动药物泵10，并通过管道将治疗药物加入输血管，药物泵10下方设置的行 星减速器会通过内侧的行星齿轮使得药物泵10的运转更加缓慢，从而致使药物在还输过程中更加的精确，并使得还输的血细胞会与治疗药物混合输入患者体内，达到治疗效果，同时当患者体内的血液在被抽离后，会刺激患者体内的造血系统和心脏等器官，而当后续将带有药物的血浆重新还输至患者体内时，则会再次刺激造血系统和心脏等器官，从而提高对患者疾病的治疗效果，改善病情。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
