RDVT-01 Drawing Volume Tester
Quantity : 1 Price : 1,00 €
应用真空采血管是一种由玻璃或塑料制成的带有彩色橡胶塞的专用容器。该塞子在管内形成真空密封，从而可以轻松抽取和控制特定体积的液体，例如血液。塞子的颜色表明管中存在添加剂，这有助于稳定和保存收集的样本以供实验室测试。这些管还可能具有安全功能，并提供标签选项，以便在医疗保健环境中进行有效跟踪和识别。测试真空采血管针的描述是双端的，为了安全起见，一侧被包裹在薄橡胶涂层中。当针头旋入半透明塑料持针器时，橡胶针头在持针器内，露出的针头将插入静脉。当真空采血管管插入支架时，其橡胶帽被内针刺破，管内的真空将血液通过针吸入管中。然后取出已填充的管子，并可以以相同的方式插入另一个管子并进行填充。从管中排出的空气量预先决定了在血液停止流动之前将有多少血液充满管。实际测试过程将测试用预抽真空管插入测试系统的穿刺部位，确保其压力与真空室内的压力相匹配。然后，根据预抽真空管使用区域的不同海拔高度，在其内部产生不同的压力值。等待1分钟后，通过测量试验前后的重量差来确定预抽管的抽吸体积。技术特点 1.PLC控制和HMI触摸屏：机组配备可编程逻辑控制器（PLC），可实现稳定的工业级控制。它拥有用户友好的人机界面（HMI）触摸屏，操作方便。2.恒压控制：该系统提供方便的数字输入机制。它自动保持罐内压力水平一致，并随着液位变化进行调整。该功能保证了测试过程的精密度和准确性。3.嵌入式真空泵：系统包含集成真空泵，有效为用户节省空间和额外成本。主要参数真空度：0~-40 KPa（近似海拔3600m）控制：PLC和人机界面电源：220V，50/60Hz
