    • A cassette for tonometric calibration especially useful for systems that measure one or more blood parameters includes a cassette having an elongated fluid chamber. In one embodiment of the invention, the fluid chamber includes an expansion region that reduces the likelihood of bubble coalescence of the calibration gas. In another embodiment, inner wall sections of the chamber are provided with a hydrophilic surface. Optionally, a fitting is non-releasably coupled to a casing of the cassette and is movable between a first position for closing a calibration gas outlet port and a second position for venting the calibration gas outlet port. In another embodiment, the cassette includes an elongated sparging tube that extends in a direction generally parallel to the longitudinal axis of the chamber.
    • 特别适用于测量一个或多个血液参数的系统的用于校准校准的盒包括具有细长流体腔的盒。 在本发明的一个实施例中,流体室包括膨胀区域,其减少校准气体的气泡聚结的可能性。 在另一个实施例中,腔室的内壁部分设置有亲水表面。 可选地,配件不可释放地联接到盒的壳体,并且可在用于关闭校准气体出口的第一位置和用于排出校准气体出口的第二位置之间移动。 在另一个实施例中,盒子包括细长的喷射管,其在大致平行于腔室的纵向轴线的方向上延伸。
