LIFEPAK 20/20e Defibrillator/Monitor
Device Description
Functional Description
(continued)
A10 SpO2 Module
can be the Masimo MS-5, MS-11 or MS-2011 oximetry
module. This patented OEM module performs all functions related to oxygen
saturation measurement, including sensor drive. Measurement results are
passed serially through the A06 OEM Interface PCB to the A02 Patient
Parameter PCB where the SpO2 data is combined with the patient ECG data
and sent to the A01 System Control PCB for display processing and storage.
The SpO2 module mounts directly to the A06 OEM Interface PCB.
A11 Active Display/
Lens
measures 14.5 cm (5.7-inch) (measured diagonally)
and uses 1/4 VGA protocol with a 320 wide by 240 high pixel array. The display
has a protective lens, held in place against the front case by a sheet metal
bracket, and an elastomeric seal. This display features full-color, high-
brightness, wide-viewing-angle capability, and is fully visible in bright-light
situations (up to direct sunlight operations). The A11 Active Display also contains
an internal backlight for visibility in low-light situations. The updated A11 LED
display 3309555 requires the use of A08 backlight driver module 3308907.
A12 Printer Module
is a 50 mm, stepper motor-driven recorder. The printer
receives serial data and commands from the A05 User Interface PCB, converts
the print data, and controls the motor-drive signals to perform the “muscle” part
of printing. The printer returns status signals derived from the paper supply
sensor and printer door to the A05 UI PCB.
