摘要： A calibration system and method for calibrating a medical sensor (16) that monitors chemical blood gases. A calibrator (12) is used in connection with a tray (14) in which the medical sensor is stored in a sterile environment, both before and during the calibration process. The medical sensor is immersed in a liquid (30) in a tonometry chamber (28) defined in the tray and covered by a membrane (120/122) that is permeable to gas, but impermeable to bacteria. During the calibration process, the tray is inserted into the calibrator, bringing a heated platen (26) into contact with the tonometry chamber, so that the liquid can be heated to a calibration temperature substantially equal to the temperature at which the medical sensor will subsequently be used. A first calibration gas is then bubbled through the liquid until a saturated condition is achieved. Once the temperature of the liquid is increased to the desired calibration temperature, as determined by a temperature sensor on the medical sensor, data for a first calibration point is taken. A second calibration gas is then bubbled through the liquid until saturation is achieved, yielding data for a second calibration point, for each of the chemical blood gas parameters. The calibration data is processed to determine calibration coefficients that will be applied to the medical sensor.
摘要翻译：一种用于校准监测化学血液气体的医疗传感器（16）的校准系统和方法。校准器（12）结合托盘（14）使用，其中医疗传感器在校准过程之前和期间都存储在无菌环境中。医疗传感器被浸入定义在托盘中的眼压测定室（28）中的液体（30）中，并被可渗透气体但对细菌不透过的膜（120/122）覆盖。在校准过程中，托盘插入到校准器中，使加热的压板（26）与眼压测定室接触，使得液体可以被加热到基本上等于医疗传感器随后温度的校准温度使用。然后将第一校准气体鼓泡通过液体直到达到饱和状态。一旦液体的温度升高到所需的校准温度，如由医疗传感器上的温度传感器所确定的，则采用用于第一校准点的数据。然后将第二校准气体鼓泡通过液体，直至达到饱和，得到每个化学血气参数的第二校准点的数据。处理校准数据以确定将应用于医疗传感器的校准系数。

摘要： A shut-off valve incorporating a tube-cutting member, and including a tubing support channel extending through the valve body. An actuator closes off, and then severs, a tubing section which is extended through the channel in the valve during an actuation stroke of the valve, the actuator including first and second spaced-apart, generally parallel slots provided in the valve body and intersecting the tubing support channel, and a driving member and first and second actuating members, each actuating member disposed in a respective slot of the valve body. During a mid-portion of the actuation stroke, the first actuating member first engages, and then closes, the tubing disposed across the first slot. At the end of the actuation stroke, after the tubing has been closed, the second actuating member severs the tubing disposed across the second slot.

摘要： An improved package for a medical device includes an inner wrap that envelopes the medical device, the inner wrap including a gas-permeable surface, and a chamber defined in the inner wrap to store a hydratable sensor of the medical device. Plumbing for the package controls fluid flow into and within the inner wrap, to selectively establish, without breaching a portion of the inner wrap surrounding the sensor, fluid communication between the gas-permeable surface and the sensor, to sterilize the sensor and the inner wrap with a gaseous sterilant, or to hydrate the sensor with hydration fluid obtained from a source of hydration fluid connected to the chamber, or to equilibrate the hydration fluid in the chamber with an external source of gas, to calibrate the sensor within the inner wrap.
