  A medical device verification system for an extracorporeal photopheresis procedure comprises a reusable irradiation device comprising a UV light source and a scanner. A fluid circuit comprises a disposable cell suspension container having a photo-reactive label comprising an identifiable code. The identifiable code is unobscured when the label in a first state and is obscured when the label is in a second state. The irradiation step is performed by irradiating the disposable cell suspension container for a predetermined period of time at or above the threshold UV irradiation level. A second input is received from the scanner during the irradiation step, the second input comprising identification of a state of the label. A response action is provided if the first input comprises identification of the second state of the label and/or if the second input comprises identification of the first state of the label.

  用于体外光子取样程序的医疗设备验证系统包括一个可重复使用的辐照装置，该装置由紫外线光源和扫描仪组成。流体回路包括一个一次性细胞悬浮液容器，容器上有一个光反应标签，标签上有一个可识别代码。当标签处于第一种状态时，可识别代码不会被遮挡，而当标签处于第二种状态时，可识别代码会被遮挡。辐照步骤是将一次性细胞悬浮液容器在阈值或高于阈值的紫外线辐照水平下辐照预定时间。在辐照步骤中从扫描仪接收第二输入，第二输入包括标签状态的识别。如果第一输入包括识别标签的第二状态和/或第二输入包括识别标签的第一状态，则提供响应操作。
