Direct Digital Writers General Information
Marquette Direct Digital Writers (DDWs) provide printing of physiologic waveforms and
patient alphanumeric information. These writing/printing devices are offered in two sizes:
the four-inch 7100 and the two-inch 7160.
The microprocessor-driven thermal print head of both models translates digitized data
directly into graphic forms on the strip chart. In contrast to conventional printers, in
which movement of the mechanism can distort waveforms and compromise accuracy, the 7100
and 7160 DDWs produce distortion-free hardcopy documentation with their stationary,
solid-state printing head. The only moving part on the otherwise completely electronic
device is the paper drive, which operates at seven different speeds.
The 7100 and 7160 graph up to four real-time waveforms simultaneously for efficient
comparison of individual physiologic parameters. Up to 3 real-time CRG waveforms are able
to be printed. The DDWs generate hardcopy printouts of stored information, including
trended parameters, arrhythmia information, cardiac, pulmonary, and dose calculations,
arrhythmia and alarm parameter and limits setup.
The 7100 and 7160 print data on a calibrated grid to ensure proper waveform alignment
on the strip chart. Both also automatically print numeric graticule increments for quick
and easy waveform assessment.
Replacing strip chart rolls is simple; just remove the spent roll, replace it with a
fresh supply and both DDWs are ready to assume operation. The 7100 and 7160 are designed
to be used with the Eagle and Tramscope 12 monitors and CD Telemetry-LAN System. |
