    摘要: Patient monitoring apparatus for use in an environment which includes a plurality of sensors. The apparatus provides collection and display of patient data signals collected from a medical patient using the sensors, including periods when the patient is being transported. The apparatus comprises a portable monitor coupled to a plurality of distinct data acquisition modules, which are coupled to the sensors. The modules includes cartridges, which detachably mount to the portable monitor, and pods which are positioned independent of the monitor. The pods reduce the number of cables extending between the patient's bed and the portable monitor by combining signals from many sensors into a single output signal. The modules collect patient data in analog form from the sensors and provide digital data signals to the monitor. The portable monitor includes: a display device for displaying the patient data, and storage for the patient data. The portable monitor may be coupled to a docking station. The portable monitor receives power from the docking station, and transfers data to a remote display device by way of the docking station. Patient data is displayed on either one of the portable monitor or the remote display device. A battery pack and a hardcopy output device attach to the case of the portable monitor.
