CHAPTER 1 ­SYSTEM DESCRIPTION

1.1 Overview

The VitaLogik bedside monitor is a standalone bedside unit consisting of a main
processing unit and a mountable color monitor.

The VitaLogik monitors the patient's vital signs.
The vital sign data derived by the VitaLogik is presented on the monitor as

waveform and numeric displays.
The VitaLogik’s user interface is especially designed for user-friendly operation.

The fixed buttons and unique QuicKnob control on the front panel of the main
processing unit enables quick and direct access to system parameters and
functions.

An optional Touch Screen is available for control of the VitaLogik setting and
menus without the hardware keys and Quicknob.

1.2 System Features and Capabilities

The VitaLogik displays a wide range of vital sign clinical parameters. It includes:

• ECG/Respiration multi-lead for monitoring ECG and respiration.

• Dual BP inputs for monitoring two invasive blood pressures.

• CO/2TMP connector to measure either thermodilution Cardiac Output or two
temperatures.

• Temp connector.

• NIBP input for monitoring non-invasive blood pressure using the oscillometric
method.

•Pulse Oximetry.

• Microstream End Tidal CO2 (EtCO2) for monitoring CO2 during exhalation
(EtCO2) and inhalation (inCO2) and Respiration Rate.

• Serial Input for communication and interface with an external, auxiliary
device.

Vitalogik is supplied in four customized configurations which are combinations of:

• Invasive / non-invasive BP/CO

• Nellcor / Masimo SPO2

In addition an optional EtCO2 Microstream option can be added.
The VitaLogik’s main monitoring features include:

• Continuously updated vital sign parameter data displayed as numeric values
and continuous waveforms.

• Clinical and technical alarm detection as well as alarm notification in audio
and visual formats.

• Easy access to collected data in the form of tabular charts and graphical trends
as well as various types of clinical reports.

• Patient data output to a recorder or a printer, if connected.

You can interact with the VitaLogik:

• Using interactive panels
These panels include menus and dialog panels that enable you to configure

system and monitoring parameters.

• Responding to Events
Fixed keys on the front panel of the main processing unit enable you to

respond quickly to events such as alarms.

1-2 Mennen Medical

VitaLogik Service Manual System Description

• Reviewing Clinical Data

Charts, Trends, Full Disclosure and Overview enable you to view and compare
data in different formats and over selected time periods.

1.2.1 Monitor and Main Processing Unit

The VitaLogik can display up to eight traces, depending on how the vital sign
display is configured. For monitor control procedures, refer to the User’s Manual.

All clinical data collected from the inputs is stored in the main processing unit.
This data includes waveforms, vital signs, trends, charts and beat-to-beat data.

The main processing unit can store at least 36 hours of patient data for review
purposes. The front panel of the main processing unit contains 5 fixed keys and the
Quicknob. These features enable you to interact with the system. The back panel
contains connectors to connect the main processing unit to other components in the
system (the display monitor and the network) and to the power supply.

A remote keypad provides direct access, via the orange keys, to the menus of V ital
signs, Patient data, and Setup, via the green keys, to Event, Print, Record, and
Freeze and by the yellow key to Timer.

This allows the user to reach these functions without opening the Main menu.

Display Features

The main screen display is divided into four areas:

• Global Header Area

• Patient Area

• Patient Display Area

• QuicKeys

1.2.2 Inputs

The Vital Signs inputs are housed on the front panel. They include:

• 12 Lead ECG/RSP

• Dual BP

•CO/2TMP

•Temp

•NIBP

• SpO2

• EtCO2 MicroStream

1.3 System Configuration Setup (Basic)

The system configuration setup consists of a Central Nurse Station (“Ensemble”)
connected through an Ethernet-LAN hub to the VitaLogik bedside monitors, local
recorder and central recorder. The VitaLogik bedside monitors and recorders are
hard-wired and remain stationary.

The BIOS setup flash memory provides the CPU card the necessary parameters
needed for initialing the Vitalogik after turning on or reset.

The Vitalogik is supplied setup for working with the Mennen Application. If any
problem arises you can setup the BIOS and select Mennen BIOS defaults. For
details, see section BIOS Setup in Chapter 6 – Maintenance.

2.1.3 Sound Card

The sound card provides an interface between the CPU card and the speaker. It
converts digital output to audio signals.

The sound card is an OEM board, for more information, see manufacturer
documentation.

2.1.4 Main Storage

The main storage consists of a hard disk 1.4 GB or higher which stores the QNX
operation system with PHOTON window manager and the Vitalogik system
application software.

The MPU stores all of a patient’s clinical data (vital signs and waveforms) on the
hard disk. These files are retrieved when the user enters the data review panels.

• The MPU also saves configuration items and user preferences on the hard
disk. A library of saved configuration sets is also maintained on the MPU’s
hard disk.

2.1.5 Main Power Supply

The main power supply supplies to all other components through the power
distribution block (J59/J60) the following DC voltages:

• Output 1: + 5V ± 0.5%. Current 12.0A

• Output 2: +12V ± 3.0%. Current 3.0A (5.0A pk)

• Output 3: +12V(ISO) ± 3.0%. Current 3.0A (5.0A pk)

Hardware System Description Vitalogik Service Manual

• Output 4: - 12V ± 3.0%. Current 3.0A

• Output 5: - 5V ± 1.0%. Current 0.6A

The output power is 110W max.

Note: Note: Outputs 2 & 3 have the same voltage and regulation, when they are

connected in parallel, output currents are added to give 6.0A .

The power supply meets UL544 or UL2601 medical standards for patient
connection specifications.

The AC input voltage is 90-230 VAC. This input is connected directly to the power
supply and to the AC output for local LCD display.

Note: There is no field adjustment or r epair. In case of malfunction, r eplace with a

new power supply supplied by Mennen Medical.

2.1.6 Front Panel

MCU (Mennen Control Unit) and RS-232 Splitter

The MCU and RS-232 Splitter provides an interface between the user console and
the CPU card, and also connects three RS-232 channels to the RS-232 (COM2) of
the CPU card.

Local Keypad and QuicKnob

The local keypad includes 12 fixed keys. Each key has a specific function (for
details see Chapter 1). The keypad and the Quicknob enable the user to operate the
Vitalogik bedside monitor.

The keypad is connected to the MCU and RS-232 splitter with a flat cable through
connector J3 that has 12 pins. Pins 1 through 9 are for the keypad. The keypad
consists of switches arranged in a row and column matrix. Up to 5 rows and 4
columns are provided for in the interface. Identification of which key was pressed
is handled by a scanning algorithm in the micro-controller. One micro-controller
port is dedicated for each row and column.

2.1.8 ECG / RSP

Overview

The multi-lead ECG/RSP module is the source of all ECG data in the Envoy
bedside monitor. The ECG is measured using a multi-lead cable via electrodes
attached to the patient’s chest.

Monitoring the ECG produces a continuous waveform of cardiac electrical activity
to enable an accurate assessment of a patient’s current physiological condition.
