For further details regarding the wireless network please refer to the M3185A Philips Clinical Network documentation.

optional recorder

optional battery

optional MSL board

optional Short Range Radio (SRR) board

Power Distribution
Figure 3 Power Distribution Architecture
The AC/DC converter transforms the AC power (100-240 V AC range) coming from the power plug into a 24 V / 50W DC source and isolates the monitoring system from the AC power mains.

The 24 V DC is distributed via the Interface Board to the optional battery charging circuit and to the mainand recorder board.

13

2 Theory of Operation

If the interface board contains the optional battery circuits, the power is used to charge the battery and supply the monitoring system. As soon as the AC power source is disconnected, the optional battery starts and keeps the system powered (battery mode). A DC/DC converter on the interface board converts the 8-12.6 V DC power supplied by the battery into 15 V DC power, which is distributed to the monitoring system.

The main board and recorder board contain power supply circuits, which convert the 24 /15 V DC into several voltages supplying the particular components of the monitoring system.
The realtime clock and the buffered RAM is supplied with cont. 3.6 V DC power, provided either by the 24 / 15 V DC system power or by the battery power and converted to 3.6 V DC.

The CPU board has an MPC852/62 MHz processor in the patient monitor that provides a number of on-chip, configurable interfaces. An array of fast UARTS with configurable protocol options are implemented in an ASIC (along with other system functions such as independent watchdogs, video, etc.), providing interfacing capabilities to integrated measurements and System Interface Boards. The serial interfaces can easily be electrically isolated. The main board contains additional video hardware.

The CPUs provide a LAN interface to connect to the Philips Clinical Network (Ethernet).
NOTE
An MP5 in companion mode does not receive its power from the host monitor via the MSL. MP5 is always powered by AC power or battery.
System Interfaces
The following is a list of Interface boards which may be present in your monitor, depending on your purchased configuration:
System Interface boards:

Basic: LAN, Video #J01(no longer orderable)

Battery: LAN, Battery Board, mCO2 #J02

Full: LAN, Battery, MIB/RS232, Video, Nurse Call, mCO2 #J40

Note that WLAN, IIT and MSL Interface require the full system interface board. The MP5T is delivered only with the battery system interface board.

The specifications for the above listed interfaces can be found in the technical data sheet for the monitor and in the Installation and Specifications chapter of the Instructions for Use.

Compatible Devices
Figure 4 IntelliVue G1/G5 Anesthetic Gas Module
Data Flow
The following diagram shows how data is passed through the monitoring system. The individual stages of data flow are explained below.
Figure 5 Data Flow
Data Acquisition
Monitoring data (for example patient measurement data in the form of waves, numerics and alerts) is acquired from a variety of sources:

Measurement Block

The integrated measurements convert patient signals to digital data and apply measurement algorithms to analyze the signals.

External measurement devices

Data can be also acquired from devices connected to interface boards of the monitor. Software modules dedicated to such specific devices convert the data received from an external device to the format used internally. This applies to the IntelliVue G1/G5 Anesthetic Gas Module.

15

2Theory of Operation

Server systems on the Philips Clinical Network

To enable networked applications such as the other bed overview, data can be acquired from server systems attached to the Philips Clinical Network, for example a Philips Information Center
Data Provider System Service

All data that is acquired from integrated measurements or external measurement devices is temporarily stored by a dedicated data provider system service. All monitor applications use this central service to access the data in a consistent and synchronized way rather than talking to the interfaces directly.

This service makes the applications independent of the actual type of data acquisition device.
The amount of data stored in the data provider system service varies for the different data types. For example several seconds of wave forms and the full set of current numerical values are temporarily stored in RAM.
Persistent Data Storage System Service

Some applications require storage of data over longer periods of time. They can use the persistent data storage system service. Dependent on the application requirements, this service can store data either in battery backed-up (buffered) memory or in flash memory. The buffered memory will lose its contents if the monitor is without power (not connected to mains) for an extended period of time. The flash memory does not lose its contents.

The trend application for example stores vital signs data in a combination of flash memory and buffered memory, while the system configuration information (profiles) is kept purely in flash memory.
Display and User Interface Service

Applications can use high level commands to display monitoring data or status and command windows on the internal LCD panel. These commands are interpreted by the display manager application. This application controls the dedicated video hardware which includes video memory and a special hardware in the ASIC.

User input is acquired from the touchscreen. The system software makes sure that the user input is directed to the application which has the operating focus.
Monitor Applications
The monitor applications provide additional system functionality over the basic measurement and monitoring capabilities. This includes for example trending, report generating, event storage or derived measurements.

In general, the monitor applications use the data provider system service to access the measurement data. Application interfaces to the other system services allow the application to visualize data, to store data over extended periods of time or to output data to other devices.

Internal LAN (Measurement Link)

The MP5/MP5T communicates as a Multi-Measurement Module (MMS) in companion mode when connected to a host monitor using an IEEE802.3/Ethernet LAN in the Measurement Link (MSL). This network is used to distribute data between the the MP5/MP5T and the host monitor, for example:

16

2 Theory of Operation

Digitized patient signals including wave data, numerical data and status information (typically from the measurement server to a display unit)

Control data representing user interactions (typically from the display unit to a measurement server)

Shared data structures, for example representing patient demographical data and global configuration items

The internal LAN allows plug and play configuration of the monitoring system. The system automatically detects plugging or unplugging of measurement servers on the host monitor and configures the system accordingly.
The components on the internal LAN are time-synchronized to keep signal data consistent in the system. Dedicated hardware support for synchronization eliminates any latency of the network driver software.

The integrated LAN provides deterministic bandwidth allocation/reservation mechanisms so that the real-time characteristic of signal data and control data exchange is guaranteed. This applies to the data flow from the measurement server to the monitor (for example measurement signal data) and the data flow from the monitor to a measurement server (for example to feed data to a recorder module).

Integrated communication hubs in the monitor allow flexible cabling options (star topology, daisy chaining of servers).
NOTE
The MP5/MP5T does not support any MMS on the MSL.
Philips Clinical Network
The monitoring system may be connected to the Philips Clinical Network, for example to provide central monitoring capabilities or other network services. This connection may be through a normal wired connection or through a wireless connection.
The monitor supports the connection of an internal wireless adapter (#J35, #J45, #J47). Switching between wired and wireless networks is automatically triggered by the plugging or unplugging of the network cable.

After configuration, the monitoring system sends the digitized patient signals including wave data, numerical data and status information onto the network. Control data representing user interactions can be exchanged between the monitoring system and a central station bi-directionally.

Additional protocols are supported for networked applications, for example for the other bed overview function, which allows viewing of monitoring data from other patients on the network.
For plug and play operation, the monitoring system uses the standard BootP protocol to automatically acquire a network address.
How does the Support Tool Work with the Monitor
The support tool is a Windows application typically installed on the laptop of a customer engineer or a biomedical engineer working in the customer’s own service department.
The purpose of the support tool is to upgrade, configure and diagnose all monitoring components in the system over the network.

17

2 Theory of Operation

The service protocol developed for this purpose uses a raw access to the devices without the need for IP addresses etc. over a standard customer network installation, so that even defective devices can be upgraded as long as the few kBytes of initial boot code are working. The boot code itself can also be upgraded using the same protocol.

The tool allows access to internal service information and to serial numbers. It can be remotecontrolled, for example via a dial-up connection from a response center, provided the proper infrastructure is in place.

For details see the Instructions for Use for the Support Tool.

Description

 

 

 

Services

 

 

Operating System

The Operating System (OS) provides a layer of isolation

 

between the specific hardware implementation and the

 

application software. The OS performs system checks and

 

allocates resources to ensure safe operation when the system

 

is first started. This includes internal self-tests on several

 

hardware modules and configuration checks for validity of

 

configuration with the operating software. During normal

 

operation, the OS continues to run checks on system integrity.

 

If error conditions are detected the OS will halt monitoring

 

operations and inform the operator about the error condition.

System Services

The System Services provide generic common system

 

services.

 

In particular:

 

They use a real-time clock component to track time. They

 

synchronize to network time sources and verify the accuracy

 

of the system time information. They are also responsible for

 

managing persistent user configuration data for all

 

Measurement parameters and IntelliVue Patient Monitoring

 

System software modules. User configuration data is stored in

 

a non-volatile read/write storage device

Applications

 

 

Reports

The Reports Service retrieves current and stored physiological

 

data and status data to format reports for printing paper

 

documentation. Examples of supported reports:

 

Vital Signs Report

 

Graphical Trend Report

 

Event Review Report

 

Event Episode Report

 

• ECG Report (12 Lead/Multi-Lead)

 

Test Report

 

The Reports service generates report data which can be

 

printed on a central printer.

Record

The Record Service retrieves current and stored physiological

 

data and status data to format a continuous strip recording. A

 

recording can be triggered manually by the operator or

 

automatically by an alarm condition. The Record Service uses

 

the services of the Recorder Interface to control a recorder.

 

The Record Service can also send data to a central recorder.

 

 

 

20

2 Theory of Operation

Functional Block

Description

 

 

Alarm

The Alarm Service contains logic that prioritizes alarm

 

conditions that are generated by IntelliVue Patient Monitoring

 

System software modules. Visual alarm signals (messages) are

 

displayed at the top of the IntelliVue Patient Monitoring

 

System display and alarm sounds are generated by a

 

loudspeaker. Alarm conditions may be generated when a

 

physiological parameter exceeds preselected alarm limits or

 

when a physiological parameter or any other software module

 

reports an inoperative status (technical alarm, for example, the

 

ECG leads may have fallen off the patient). The Alarm service

 

manages the alarm inactivation states, for example suspension

 

of alarms, silencing of alarms, and alarm reminder. Alarm

 

signals may also be configured as latching (alarm signals are

 

issued until they are acknowledged by the operator, even

 

when the alarm condition is no longer true). The Alarm

 

service controls the visual alarm signals (alarm lamps).

Trend

The Trend service stores the sample values of physiological

 

data and status data with a resolution of 12 seconds, 1 minute

 

or 5 minutes for a period of up to 48 hours. The data is kept

 

in battery buffered read/write storage and flash memory

 

devices to be preserved across power failures. The stored data

 

is protected via consistency checks and checksums. When a

 

new patient is admitted, the trend database erases all data of

 

the previous patient.

OxyCRG

The OxyCRG (Oxygen CardioRespiroGram) service derives a

 

high-resolution trend graph from the Beat-to-Beat Heart

 

Rate, SpO2, and Respiration physiological data. The OxyCRG

 

is specialized for neonatal applications, allowing the operator

 

to identify sudden drops in Heart Rate (Bradycardia) and

 

SpO2 (Desaturation), and supporting the operator in

 

visualizing Apnea situations.

ADT

The ADT (Admit/Discharge/Transmit) service maintains the

 

patient demographics information. The operator may admit a

 

new patient, discharge the old patient and enter or modify the

 

patient demographics.

Calc Param

The Calc Param (Calculated Parameters) application performs

 

calculations on physiological numerical values to derive

 

calculated parameters like Temperature Difference.

Interface Managers

 

 

 

21

2 Theory of Operation

Functional Block

Description

 

 

MDSE

The MDSE (Medical Data Service Element) Interface

 

Manager is responsible for the exchange of real-time data

 

between the IntelliVue Patient Monitoring System display unit

 

and the Measurement parameters and other devices attached

 

to the network. MDSE establishes and maintains a data

 

communication link between the devices. It provides

 

configuration information about the remote device to

 

applications in the local device and it allows the exchange of

 

measurement data and status information between the

 

devices.

Printer

The Printer Interface Manager provides a high level interface

 

to a printer. It provides means to:

 

• establish a connection to the printer

 

• transfer data to the printer

 

• get status of the printer

 

• close connection to the printer

 

The Printer Interface Manager also supervises the connection

 

to the printer and whether the printer accepts data (for

 

example paper out). The Printer Interface Manager notifies

 

the operator in such cases.

Display & Operator Interface

The Display and Operator Interface Manager performs the

 

following tasks:

 

• Screen presentation of real-time and stored physiological

 

measurement data, alarm condition data and status

 

information received from the MDSE interface manager,

 

the Alarm service or other IntelliVue Patient Monitoring

 

System modules

 

• Screen presentation of operating controls (control

 

windows)

 

• Processing of operating control commands received from

 

HIF Control interface. The module verifies and interprets

 

the received commands and forwards them to other

 

software modules of the IntelliVue Patient Monitoring

 

System display unit or measurement parameters.

 

• Sound generation (issues audible alarm signals and

 

generates audible information signals, for example QRS

 

and SpO2 tones, operator audible feedback)

Interfaces

 

 

 

22

2 Theory of Operation

Functional Block

Description

 

 

LAN

The LAN interface implements the physical layer of IEEE

 

802.3. The LAN interface performs Manchester encoding/

 

decoding, receive clock recovery, transmit pulse shaping,

 

jabber, link integrity testing, reverse polarity detection/

 

correction, electrical isolation, and ESD protection.

 

Electronically separated interfaces are used for

 

communication to the Measurement parameters and to the

 

network.

Display Controller

The Display Controller Interface consists of a video

 

controller, video RAM and the controlling software. The

 

Display Controller interface processes the high level display

 

commands (character and graphic generation, wave drawing)

 

and translates them into pixels, which are written into the

 

video RAM where the video controller chip generates the

 

video synchronization signals and the pixel stream for the

 

Color LCD Display.

HIF Control

The HIF (Human Interface Control) interface scans the

 

Human Interface devices for operator controls (Touch

 

Screen), formats the collected data and sends it to the display

 

and Operating Interface.

ECG-Out Marker-In

The ECG Out/Marker In interface receives the ECG

(not for MP5T)

waveform directly from the ECG/Resp Arrhythmia ST-

 

Segment physiological algorithm running on the main CPU

 

and converts the digital ECG signal to an analog ECG signal.

 

In addition, the ECG Out hardware receives from a

 

connected device the marker information and forwards this

 

data to the ECG/Resp Arrhythmia ST-Segment physiological

 

algorithm. The converted analog signal is used to synchronize

 

a connected device to the patient’s ECG

Nurse Call

The Nurse Call board contains a phone jack type connector

(not for MP5T)

with a single close-on-alarm relay.

MIB

The MIB interface allows full-duplex, short-haul

(not for MP5T)

asynchronous binary communication between the monitor

 

and an arbitrary (medical/non-medical) device using an eight-

 

pin RJ45 modular connector. Communication protocols using

 

this interface can be configured.

ECG Sync Out

A pulse signal is provided on the RS-232 interface to allow

(not for MP5T)

synchronisation with other medical devices.

Testing and Maintenance

Introduction
This chapter provides a checklist of the testing and maintenance procedures to ensure the performance and safety of the monitor.

These tests must be performed only by qualified personnel certified by the responsible organization. Qualifications required are: training on the subject, knowledge, experience and acquaintance with the relevant technologies, standards and local regulations. The personnel assessing safety must be able to recognize possible consequences and risks arising from non-conforming equipment.

All recurring safety and performance assurance tests must be performed under equal environmental conditions to be comparable.

Preventive Maintenance refers specifically to the series of tests required to make sure the measurement results are accurate. The accuracy and performance procedures are designed to be completed as specified in the following sections or when readings are in question.

For detailed instructions on the maintenance and cleaning of the monitor and its accessories, see Care and Cleaning, Using Batteries and Maintenance and Troubleshooting in the monitor's Instructions for Use.
Terminology and Definitions
The following terms and definitions are used throughout this chapter and taken from the international standards IEC 60601-1, IEC 60601-1-1 and IEC 62353.

Medical System: a medical electrical system is a combination of at least one medical electrical device and other electrical equipment, interconnected by functional connection or use of a multiple portable socket-outlet.

Patient Vicinity: any area in which intentional or unintentional contact can occur between the patient and parts of the medical system or between the patient and other persons who have had contact with parts of the medical system.
