Theory of Operation

Monitor Theory of Operation

The IntelliVue MP80/MP90 Patient Monitor:

-displays real-time data

-controls the attached measurement servers

-alarms in the case of patient or equipment problems

-offers limited data storage and retrieval (trending)

-interfaces to the Philips Clinical Network and other equipment

A monitor with just a single integrated measurement server can be connected to additional building blocks to form a monitoring system with a large number of measurements, additional interface capabilities and multiple slave displays. These elements cooperate as one single integrated real-time measurement system.

Power Supply

The AC/DC converter transforms the AC power coming from the power plug into 48 V/120W DC source and isolates the monitoring system from the AC power mains.The 48V is distributed via power bus and supplies power to all the components of the system: The 56 V DC power needed for the FMS, MMS and MMS Extension is created by an isolating DC/DC converter. The CPU is supplied with 3.3 V and 5 V DC power. The transformation is performed in two steps: The first DC/DC converter is a power regulator which reduces the variations caused by load changes on the 48V power bus. The second DC/DC converter converts the power to the needed voltage. Interface boards require a power of 10V AC.

CPU Boards

The CPU boards have an MPC860 50 MHz or MPC86x 100 MHz processor that provides a number of on-chip, configurable interfaces. An array of 12 fast UARTS with configurable protocol options are implemented in an ASIC (along with other system functions such as independent watchdogs etc.), providing interfacing capabilities to measurement modules and I/O boards. The serial interfaces can easily be electrically isolated. The main board contains additional video hardware.

The CPUs provide two LAN interfaces to interconnect CPUs (via the MSL) and to connect to the Philips Clinical Network.

The CPU capabilities are identical. Different loading options are coded on serial EEPROMs to support the automatic configuration of the operating system at boot time.

18

Monitor Theory of Operation

2 Theory of Operation

I/O Boards

Interfaces to the monitor are implemented via I/O boards. The location of these boards is restricted by general rules. The I/O slot designations diagram and the I/O matrix which outline the I/O board placement rules can be found in the Installation Instructions section.

The following is a list of Interface (I/O) boards which may be present in your monitor, depending on your purchased configuration:

-MSL

-Video (analog)

-Philips Clinical Network (LAN wired or wireless)

-Basic Alarm Relay (Nurse Call)

I/O boards:

-PS/2

-MIB/RS232

-USB

-Flexible Nurse Call

-Parallel printer

-Remote devices (Remote Alarm Device, Remote Extension Device)

-IntelliVue 802.11 Bedside Adapter

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.

Data Flow

The following diagram shows how data is passed through the monitoring system. The individual stages of data flow are explained below.

19

2 Theory of Operation

Monitor Theory of Operation

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 Servers

The Measurement Servers connected to the internal LAN 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 parameter modules and the Anesthetic Gas Module.

-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 measurement servers 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 temorarily 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.

20

Monitor Theory of Operation

2 Theory of Operation

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 ASIC.

User input is acquired from a variety of input devices, for example the SpeedPoint, the touchscreen or other standard input devices (keyboard, mouse) which may be attached to I/O boards. The system software makes sure that the user input is directed to the application which has the operating focus.

Data Output

The monitoring system is very flexible and customizable regarding its data output devices. Built-in devices (for example LAN, alarm lamps, speaker, video) provide the basic output capabilities.

These capabilities can be enhanced by adding additional I/O boards, as required in the specific end-user setup. The additional I/O boards typically provide data to externally attached devices, for example to printers, RS232 based data collection devices, nurse call systems etc.

The monitor can identify I/O boards by means of a serial EEPROM device that stores type and version information. The operating system detects the I/O boards and automatically connects them with the associated (interface driver) application. For some multi-purpose cards it is necessary to configure the card for a particular purpose first (for example the dual MIB/RS232 card can support external touch display , data import, data export).

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.

21

2 Theory of Operation

Monitor Theory of Operation

Internal LAN (Measurement Link)

All components of the monitoring system (including measurement servers and CPUs in the monitor) communicate using an IEEE802.3/ Ethernet LAN in the Measurement Link (MSL). This network is used to distribute data between the components, for example:

-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 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 and the FMS allow flexible cabling options (star topology, daisy chaining of servers).

22

Monitor Theory of Operation

2 Theory of Operation

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 external wireless adapter or an internal wireless adapter (#J35). Switching between wired and wireless networks is automatically triggered by the plugging or unplugging of the network cable.

The Philips Clinical Network protocols function very similarly to the protocols used on the internal LAN.

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 (modules, measurement servers, and monitors) in the system over the network.

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 Servers, Flexible Module Racks

 

and IntelliVue Patient Monitoring System software

 

modules. User configuration data is stored in a

 

non-volatile read/write storage device

 

 

Applications

 

Application Server Client

The Application Server Client provides the Citrix1 thin

The Reports service generates report data which can be

 

printed on a local or 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 an M1116B Recorder in the FMS. The Record

 

Service can also send data to a central recorder.

Description

Alarm

The Alarm Service contains logic that prioritizes alarm

 

conditions that are generated either by the Measurement

 

Servers, Flexible Module Rack, or 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.

HiRes

The OxyCRG (Oxygen CardioRespiroGram) service

 

derives a high-resolution trend graph from the

 

Beat-to-Beat Heart Rate, SpO2 or tcpO2, and Respiration

 

physiological data. The OxyCRG is specialized for

 

neonatal applications, allowing the operator to identify

 

sudden drops in Heart Rate (Bradycardia) and SpO2 or

 

tcpO2 (Desaturations), 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. The ADT service also

 

supports the transport of a patient (trend database) with

 

the M3001A Multi-Measurement Module. The ADT

 

service controls the deletion of old patient data, the

 

upload of trend data from the M3001A and the switching

 

back of all settings to user defaults. It also synchronizes

 

patient information with a central station on the network.

Description

Calc Param

The Calc Param (Calculated Parameters) service accesses

 

current, stored and manually entered physiological data as

 

input to calculation formulas. With these formulas,

 

derived hemodynamic, oxygenation and ventilation

 

variables are computed. The calculation results, including

 

the input parameters, are stored for later review using the

 

Trend service.

Drug Calc

The Drug Calc application aids in calculating drug

 

dosages for patients.

PV Loops

The PV Loops application compares graphic

 

representations of airway waves to help detect changes in

 

the patient airway condition.

Interface Managers

 

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 Servers and Flexible Module

 

Rack as well as between the IntelliVue Patient

 

Monitoring System display unit 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.

Description

Display & Operator

The Display and Operator Interface Manager performs the

Interface

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, Measurement

 

Servers or Flexible Module Rack

 

- Sound generation (issues audible alarm signals and

 

generates audible information signals, for example

 

QRS and SpO2 tones, operator audible feedback)

Interfaces

 

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 Servers or Flexible

 

Module Rack and to the network.

Centronics

The Centronics interface implements the standard

 

signaling method for bi-directional parallel peripheral

 

devices according to IEEE 1284-I. The interface is used

 

as a parallel interface to a standard printer with electrical

 

isolation and ESD protection.

Description

Display Controller

The Display Controller Interface consists of a video

 

controller chip, 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, Speed Point, USB and PS/2 devices), 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

 

waveform directly from the ECG/Resp Arrhythmia

 

ST-Segment physiological algorithm via an RS-422 serial

 

interface and converts the digital ECG signal to an analog

 

ECG signal. In addition, the ECG Out controller 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

RS-422

The serial link RS-422 interface communicates the ECG

 

signal to the ECG Output/Marker In of the IntelliVue

 

Patient Monitoring System display unit. The interface is a

 

serial, differential, full-duplex link. The interface is ESD

 

protected.

PS/2

The PS/2 interface supports the serial protocol of standard

 

PS/2 devices (mouse). The PS/2 serial protocol is

 

interpreted by the HIF Control interface.

Nurse Call

The Nurse Call board contains 2 connectors. A phone

 

jack type connector and a multi-port connector. The

 

phone jack type connector has a single close-on-alarm

 

relay. The multi-port connector has three alarm relays

 

which are configurable to be open or closed on alarm. In

 

addition, this interface has an audible alert capability for

 

loss of AC power.

MIB

The MIB interface allows full-duplex, short-haul

 

asynchronous binary communication between the monitor

 

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

 

eight-pin RJ45 modular connector. Switching between

 

MIB and RS232 protocol is possible.
