2 FUNCTIONAL DESCRIPTION

2.1 Introduction

The deioRecorder for Anesthesia is an automated anesthesia documentation system. For record
keeping the deioRecorder for Anesthesia software license, the record keeping configurations from
network and memory module and optionally the keyboard for the deioRecorder for Anesthesia, K­ARKB is needed.

The deioRecorder for Anesthesia is connected to a network, and run in S/5 AM or S/5 CM. Memory
Module, M-MEM (N-CMMEM) is needed for data storage as a backup.

The deioRecorder for Anesthesia combines the physiological data measured by the monitor,
information automatically integrated from external devices as S/5 ADU and the information
entered manually using the menus into a printable anesthesia record. The record can be stored in
electronic format for later review/printing and for statistical analysis.

2.2 Keyboard for the deioRecorder for Anesthesia, K-ARKB

The keyboard for the deioRecorder for Anesthesia, K-ARKB consists of the controller board,
alphanumeric keyboard and membrane keyboard.

2.2.1 Controller Board

The controller board reads the status of the keyboard keys and the ComWheel, and forwards the
information to the CPU board, in the monitor through RS232 serial interface.

Additionally, the board controls the LEDs on the K-ARKB front panel.

External communication

Communication with the CPU board, takes place in RS232 serial communication channel which is
available in the CPU bus. There are also two bidirectional signals (Data and Clock) for PCKB format
communication.

For serial communication, the keyboard for the deioRecorder for Anesthesia is connected to the
S/5 Anesthesia Monitor 8-Module Frame by 9-pin-26-pin interface cable. The cable is connected
to Keyboard Interface Board, B-ARK or to Display Controller board, B-DISP (or B-DHIGH), in the F­CU8.

In case of PCKB type communication, the Keyboard can be connected to the S/5 LCD Display, D­LCC10A or to the S/5 CM.

CPU

The CPU on the controller board is of a type 80C51FA and the oscillator frequency is 11.059 Mhz.
There is a power-up-reset whose time constant is about 1 second.

Serial communication

The RS232 serial communication IC needs only +5 V supply voltage because it chops the
necessary RS-level supply voltages to its external capacitors. A diode allows the use of two
keyboards, and a pull-down resistor on the CPU board is used for pulling the corresponding line to
the negative RS-level. The speed rate of the serial communication is 19.2 kbps.

S/5 Anesthesia Record Keeping Keyboard and Barcode Reader

LEDs

The CPU on the controller board controls the alarm LEDs according to commands received from the
main CPU board.

2.2.2 Alpha-numeric keyboard

The controller board reads the status of the keys on the alphanumeric keyboard. The board are
connected together with a 26-pin ribbon cable.

2.2.3 Membrane keyboard

The controller board reads the status of the keys on the membrane keyboards. The membrane
keyboard and the controller board are connected together with a ribbon cable.

2.3 Keyboard Interface Board, B-ARK

The Keyboard Interface Board, B-ARK is installed in the 8-Module Frame of the S/5 Anesthesia
Monitor. It has a 26-pin D-connector to which the Keyboard for the deioRecorder for Anesthesia, K­ARKB is connected. The board passes the keyboard signals to the F-CU8.

2.4 ARK Barcode Reader, N-SCAN

The Datex-Ohmeda ARK Barcode Reader, N-SCAN is an optional device to make record keeping
faster by using bar codes. With the Barcode Reader user have a direct access to a menu item by
reading a bar code mapped to the menu item. Barcodes can also be used for pushing and turning
the ComWheel and opening the main menus (L-ARK99(A) or later).

WARNING When using the ARK Barcode Reader, N-SCAN do not stare into beam. The ARK

Barcode Reader, N-SCAN is a Class 2 laser product.
