Power Distribution

Power Distribution Architecture

Monitor Theory of Operation 2 Theory of Operation

The DC/DC converter transforms the DC power (36-60 V DC range) coming from the MSL plug into a 16 V DC source and isolates the monitoring system from the DC MSL.

The 16V DC is distributed via the Power Board to the battery charging circuit and to the main board.

The power is used to charge the battery and supply the monitoring system. As soon as the DC power source is disconnected, the battery starts and keeps the system powered (battery mode).

The main board contains power supply circuits, which convert the 16 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 16 V DC system power or by the battery power and converted to 3.6 V DC.

The CPU board has an MPC852 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. The main board contains additional video hardware.

The CPU provides a LAN interface to connect to the Philips Clinical Network (Ethernet).

System Interfaces

The LAN interface on the Measurement Link (MSL) is used as the network interface.

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

- External measurement devices

- Server systems on the Philips Clinical Network

Persistent

Data

Storage

Data

Output

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

Data can be also acquired from devices connected to the monitor. Software modules dedicated to such specific devices convert the data received from an external device to the format used internally.

To enable networked applications, data can be acquired from server systems attached to the Philips Clinical Network, for example a Philips Information Center

2 Theory of Operation Monitor Theory of Operation

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.

Monitor Theory of Operation 2 Theory of Operation

Internal LAN (Measurement Link)

The MP2/X2 communicates using an IEEE802.3 Ethernet LAN in the Measurement Link (MSL). This network is used to distribute data between the components, for exam ple:

- 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 X2 to the host monitor (for example measurement signal data) and the data flow from the host monitor to an X2 (for example to feed data to a recorder module).

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.

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.

For plug and play operation, the monitoring system uses the standard BootP protocol to automatically acquire a network address.

2 Theory of Operation Monitor Theory of Operation

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 componen ts 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.

The figure below shows the functional block diagram for the monitoring system. A legend explaining terms and diagram elements follows. The information below varies depending on the purchased monitor options.

Functional Block Diagram

Monitor Theory of Operation 2 Theory of Operation

Block Diagram Legend

Functional Block 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.

2 Theory of Operation Monitor 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.

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 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.

Monitor Theory of Operation 2 Theory of Operation

Functional Block Description

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 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. Sync Out (ECG) A pulse signal is provided on the Sync Out connector to allow synchronisation

with other medical devices. IIT The built-in IIT module allows operation of the MP2/X2 monitors within

IntelliVue Instrument Telemetry Infrastructure. WLAN The built-in WLAN interface allows wireless operation of the X2/MP2 monitors

with the IntelliVue 802.11 Bedside Adapter SRR The built-in SRR interface allows wireless communication of the MP2/X2

monitors with an IntelliVue Instrument Telemetry Transceiver. MSL All components of the monitoring system communicate using an IEEE802.3/

Ethernet LAN in the Measurement Link (MSL). This network is used to

distribute data between the components
