Overview and Functional Description

The M2636B TeleMon Companion Monitor is a telemetry extension device providing non-invasive blood pressure (NBP) capability, a bedside/patient-side monitor/display, and isolated line power or battery power to extend the M2601A Telemetry Transmitter battery life.

As part of the Telemetry System, TeleMon with a docked transmitter provides local display of ECG waveforms, a pleth wave, a delayed/annotated ECG wave, heart rate, %SpO2, and NBP while simultaneously transmitting ECG, %SpO2 and NBP via a unidirectional RF telemetry link to the Information Center. This is provided by TeleMon within the antenna system coverage area. At the central station, a “docked transmitter” indication will be displayed to distinguish data being sourced from a transmitter docked with TeleMon.

Introduction

System Compatibility

Information Messages and Alarms

The M2636B TeleMon Monitor is designed for use with the Telemetry System Series C, and either a conventional Series C or EASI

The communication from the transmitter to the TeleMon is via an infrared port on the transmitter.

Patient alarms are generated and annunciated at the Information Center and at TeleMon B when local alarms are enabled. TeleMon displays information messages; these messages are also displayed in the patient sector at the Information Center, along with the ECG waveforms and SpO

and NBP readings.

transmitter.

Ambulatory Use The transition to ambulatory monitoring is seamless, given that the same transmitter

continues to source patient data and no user interaction is required to continue monitoring. The clinician needs only to remove the transmitter from TeleMon.

Monitor Assembly The Monitor Assembly contains

• the Chassis Assembly, on which all the PC boards are located.

• the Rear Housing assembly, in which the transmitter dock, the battery compartment, the cooling fan and the speaker are mounted.

Chassis Assembly The Chassis is a metal plate. To one side of it three PC boards are fastened,

containing the major electronics of the TeleMon. The LCD is fastened to the other side.

Main Board Assembly

The Main Board (Figure 6-14 on page 6-42) contains:

• ICs required to store the software and perform the logic of measurement, analysis, calculation and display.

• Coin battery for the Real Time (RT) clock. This clock provides time stamps for data and times the transfer of data to and from TeleMon.

• Keyed connectors for the cables that supply power and control data to units performing specialized functions, such as display or NBP measurement. Each connector is uniquely keyed to prevent any misconnection. All power comes from Main Board circuits.

• The OFF/ON Power Switch, which extends through an opening in the left side of the rear housing when the unit is fully assembled. The switch performs the following functions:

– When ON, applies line power to the Main Board if the External Power

Supply is connected.

– When ON, applies battery power to the Main Board if the External Power

Supply is not connected.

Page 18

Hardware

– When OFF, applies line power to the battery for charging if the External Power

Supply is connected. Only the various power and battery indicators are functional.

– When OFF, shuts off all power if the External Power Supply is not connected. The

coin battery on the Main Board continues to drive the Real Time (RT) clock and some memory circuits.

• The External Power Connector, which extends through an opening in the rear housing. Use of this connector feeds power from the External Power Supply to the Main Board, which may also distribute it to other modules.

• Serial Port. The Serial Port Connector on the Main Board is accessed through an opening at the bottom of the Rear Housing. The port is used for software updates. The opening is covered by a snap-lock door.

• Optical devices. The transmitter communicates with the TeleMon, when docked, through an infrared (IR) path. IR data is reflected onto an optical device on the Main Board through a perforation in the IR Shield. Another device provides a control and data path to the transmitter through a second perforation.

The NBP Board

The Inverter Board

The Non-invasive Blood Pressure (NBP) Board (Figure 6-9 on page 6-38) performs operations relating to taking a blood pressure with the cuff. The NBP Board contains:

• IC’s for regulating the operation of the Air Pump.

• A connector for the NBP-to-Main Cable.

• The Air Pump with mounting device. The pump is specified for at least 30,000 cycles before it needs to be replaced; 10,000 cycles before it needs to be calibrated.

• Conduit tubing for the air.

The Inverter Board (Figure 6-10 on page 6-39) applies 380 VAC at 5 mA to the LCD’s backlight, which is fluorescent. An oscillator in the inverter circuit changes DC input current from either the 10.8 battery or the external power supply to AC.

The Inverter Board Assembly consists of:

• A metal shield to limit radiation from the inverter circuits.

• The Inverter Board.

• Integral connectors for the Inverter-to-Main and Inverter-to-Display Cables.

The Rear Housing Assembly consists of:

• Molded plastic rear housing.

• Speaker Mount (Figure 6-16 on page 6-44), a formed stainless metal piece bent into extensions for the Speaker mount and the data path reflector. Coded optical beams from a docked transmitter are reflected onto the optical receptor of the Main Board and beams from the emitter on the Main Board are reflected into the transmitter. Broken beams are interpreted by software in the processing unit of the Main Board as an undocked transmitter. On the outside of the Rear Housing, the NBP Cuff Holder is screwed to the Speaker Mount through the housing.

• Cooling Manifold Assembly, a formed metal piece fastened to the Rear Housing above the Transmitter Dock. A small cooling fan with integral drive motor is fastened to it. From the fan housing extends the Fan-to-Main Cable. Cooling and venting are facilitated by slots in the bottom and top rear surfaces of the Rear Housing, perforations on the side of the Rear Housing, and large perforations in the Battery Housing. The fan is powered by the OFF/ON switch at the side of the monitor.

• Transmitter Dock (Figure 6-19). Three interlocking plastic pieces forming a dock that fits into the docking port on the side of the Rear Housing. The Dock screws to mounts on the Rear Housing. The screws also hold the dock together. The Transmitter-to-Main power cable interlocks to the back of the Dock and terminates in a connector for Main Board attachment. An integral latch furnishes some resistance to docking and undocking the transmitter, and holds the transmitter in place. An opening in the top of the Dock passes optical data streams between the transmitter and the Main Board via a reflector surface on the Speaker Mount. All ECG and SpO transmitter. All RF transmission between the monitor and the Information Center requires docking and ECG cables and leads.

Page 22

Environmental Considerations

The monitor should be used in an area reasonably free from vibration, dust, corrosive or explosive gases, and extremes of temperature and humidity. The following paragraphs give information concerning environmental considerations.

Temperature The monitor operates within specifications at ambient temperatures between 0 and 35

Celsius. Temperatures exceeding these limits could affect instrument accuracy and cause damage.

Operating

Operate and store TeleMon at altitudes up to 3,048 meters (10,000 feet).

Altitude

Radio Frequency Interference

Management of the RF environment in your facility is important to the overall performance of your telemetry system, including the monitor. The considerations are the same. In most cases, use of the monitor implies that the Telemetry System is already in place and the RF environment has already been taken into consideration. For full coverage of this topic, refer to the Telemetry System documentation, especially Chapter 2 of the Service Guide.

WarningWarning

TeleMon units containing transmitters that are 25 kHz apart in transmitter frequency interfere with one another at distances of 1-3 feet. This situation is aggravated by ECG cable proximity. Symptoms include dropout (at the information center), waveform artifact of the ECG (at central and TeleMon), and screen freeze (at TeleMon). To avoid this situation, maintain a distance of >3 feet between TeleMon units.

3-2 Site Planning—Specific Requirements

Page 23

Power Requirements

The monitor is a mobile extension of the Telemetry System and can display and broadcast information through the antenna on battery power alone for up to a five hours. However, for bedside use it should be connected to a grounded wall outlet through its own external power supply. The bedside wall outlet should provide input of 100 - 250 VAC at 50 - 60 Hz. The monitor and therefore the bed need to be within 6 feet of where the external power supply is to be mounted. The line cord between the wall outlet and the external power supply must be grounded and routed and/or mounted to avoid accidental tripping or pulling.

The External Power Supply must be grounded during operation. If a 3-wire receptacle is not available, then a hospital electrician must be consulted to ensure that proper grounding is available on installation. Never attempt to use a three-wire to a two-wire adaptor with the External Power Supply. For details, see the “Electrical Specifications” on page 9-10.

Note—The TeleMon battery may not arrive at your site fully charged due to time in transit or

storage. Make sure that the battery is fully charged before using TeleMon.

Power Requirements

Antenna System Site Information

Antenna Coverage Area

All transmitter information is available at the TeleMon, whether or not the transmitter is in the antenna coverage area. However, if the TeleMon is outside the antenna coverage area, there is no communication to the Information Center and no indication at the TeleMon that the RF signal is not being received at the Information Center. Outside the coverage area, no alarms can be generated at the Information Center.

Page 26

Placement on a Flat Surface

The easiest and most mobile way to mount the TeleMon is simply to stand it on a flat surface. The monitor needs to be visible and in a safe place, as free as possible from the danger of accidental pulling, knocking over, or spilling of fluids.

The simplest placement of the External Power Supply is on the floor near the TeleMon. The power output cable allows a distance from TeleMon of six feet. Do not place the monitor where it can be pulled down onto the patient. The power input cord should run directly to the wall wherever possible. It should not be strung across a passage.

WarningWarning

To avoid the risk of accidental entanglement and strangling, place or mount the AC power cabling away from the patient. Use similar caution in temporarily storing ECG, NBP or SpO2 cables.

WarningWarning

4-2 Installation

Page 27

Mounting on a Pole

Mounting on an IV pole combines mobility with stability. The External Power Supply can be mounted apart or near the TeleMon on the same pole. For example, mount the power supply at the bottom of the IV pole.

Note—The power input cord must run from the TOP of the power supply to the monitor, to

avoid seepage of spills into the plug on the other side (Figure 4-2).

For pole mounting, use the Pole Clamp, Part Number 5061-8363, which can support a maximum load of 14 pounds (6.5 kg).

Mounting on the Wall (General)

Wall mounting requires the most preparation and is the most stable, but least mobile, configuration.

Caution

These mounting instructions are neither applicable in California nor sanctioned by the California OSHPD for installation in the State of California, U.S.A., in conformance to that state’s requirements for seismic protection.

The following instructions describe surface wall mount base installation to a wall.

Before instruments have been installed, the hospital or other facility, its consultants, or its contractors shall be responsible for meeting the following conditions:

• That the wall is adequate to safely mount monitoring instruments, including the selection of fasteners and their proper installation.

Mounting on the Wall (General)

• That the installation has been completed in accordance with accepted standards of good workmanship.

• Anchorage or support in a metal stud or wood stud wall must be verified by a registered professional engineer before installing the mounting system.

Installation 4-5

Page 30

Mounting on the Wall (General)

WarningWarning

Existing wall construction and reinforcement:

The wall mounts must be capable of supporting four times the specified weight capacity after they have been properly installed. To provide this support in plaster, plasterboard, or gypsum board walls, the wall covering must be removed in the area of work and a reinforcement must be provided within the wall structure.

Do not install a wall mount onto solid brick or brick veneer walls, or onto crumbly wall material such as cinder blocks or deteriorated concrete or concrete block.

Ensure that no electrical wiring, piping, or other utilities within the wall interfere with or can be damaged by the installation process.

Fastenings:

Lead expansion bolts or plastic expansion anchors specifically are not adequate or safe. Use the anchors specified for solid concrete construction.

Never mount heavy instrumentation to plain gypsum board using expansion anchors. The wall covering (plasterboard or plaster) must be removed and the wall must be reinforced internally, in new or existing construction.

In Installation:

No portion of the mount or mainframe may extend over a patient’s bed.

Never exceed the maximum rated load specified on the label(s) attached to the wall mount in use.

Never exceed any maximum instrument stacking height specified on the label(s) attached to the wall mount in use.

Do not attempt to remove any wall mount while instruments are attached.

The wall mount is mounted directly to the wall. All mountings and anchorages must conform to local building codes and regulations. A variety of mounts are available and can be purchased, or the user can devise his own, provided it conforms to the warnings and regulations stated in this manual.

Installation consists of building a mount to which the Dovetail or External Power Supply Bracket are fastened. The monitor then slides and snaps onto the Dovetail and the External Power Supply slips into its bracket. The bracket can also be mounted directly on the wall.

In general, wall mounts must be installed securely to the wall’s internal structure with number 10 sheet metal screws, 1/4-20 or 10-32 pan head machine screws, or bolts with nuts or toggle wings. The type of fastening and method depends on the wall construction.

Note—Machine screws have built-in lock washers or other means of securing threads. All

sheet-metal screws have type-A threads.

4-6 Installation

You can install the mount base in three ways:

1. On Hollow Block or Hollow Tile Walls.

2. On Solid Concrete or Solid Block Walls.

3. On Drywall.

Troubleshooting

Purpose This section provides troubleshooting instructions for TeleMon. To properly troubleshoot

TeleMon, a clear understanding of the Telemetry system is required.

When troubleshooting TeleMon consider that problems can occur because of:

• Equipment malfunctions: hardware failures, etc.

• Application faults: usually leads off, battery problems, ECG equipment malfunction, transmitter malfunction, %SpO

• RF problems: as a result of RF environmental conditions, or problems like not receiving a signal, receiving a weak signal, etc. (Solutions to this type of problem are described in the Telemetry System Service and Reference Guide.)

This section presents symptoms that show up when failures occur, and provides a corrective action to fix those failures. In this section you will find:

• Alarms and Information Messages

• Self-test Error and Event Log Messages

• NBP Event Log Error Codes

• Additional Troubleshooting Tips

•Power O2

Alarms and Information Messages

Patient Alarms When a transmitter is docked in TeleMon, all patient alarms are generated, displayed,

Two types of signals can be generated during monitoring:

• Patient alarms indicate a life-threatening situation or less urgent situation, such as heart rate alarm.

• Information messages indicate that the monitor cannot measure or detect alarm conditions reliably.

recorded, and silenced either at TeleMon locally, or at the Information Center and Surveillance Center.

WarningWarning

No patient alarms are annunciated at the TeleMon when local alarms are off. When local alarms are off, telemetry alarms are presented at the central monitor only, and all alarm adjustments must be made at central.

All central alarms can be temporarily suspended for 3 minutes from TeleMon. When alarms are suspended at TeleMon, any active alarm will be silenced. When alarms are unsuspended, the arrhythmia time outs will be reset.

NBP alarm settings (limits and on/off) are adjusted at central.

Visual Indicators on TeleMon for Patient Alarms:

• Message CENTRAL ALARMS ONLY displayed in black on top banner

• Message Local Alarms OFF displayed in alarm message area.

Suspending

Patient Alarms

You can suspend central telemetry alarms from TeleMon for 3 minutes to prevent false alarms from occurring during a change of electrodes or other activity that could cause motion artifact alarms.

Visual Indicators on TeleMon for Suspended Alarms:

• Message CENTRAL ALARMS SUSPENDED displayed in red on top banner

opposite the date.

• Number of minutes remaining in the suspension period displayed above the Suspend Alarms key.

• The SUSPEND at Central key label changed to xx:xx min to UN SUSPEND.

Note—When the transmitter is undocked, the suspend capability reverts to standard telemetry

operation; that is, suspend is enabled at central.

Task Summary To suspend alarms at central from TeleMon, use the following procedure.

Step 1. Press the key below SUSPEND at Central to suspend all telemetry alarms at

central for 3 minutes.

Step 2. To restart suspended alarms, press xx:xx min to UNSUSPEND.

Information

Messages

The following table lists all the information messages that TeleMon can display. These messages are text only; no sound is generated at TeleMon when any of these conditions is active.

WarningWarning

When local alarms are off, information messages at TeleMon are silent.

If multiple information messages are active, an up arrow (↑) will be displayed to the right of the information message area. Messages will cycle through the sector at a rate of one every two seconds. There is no audible indicator for any information signal.

All information messages are non-latching, that is, the information message resets automatically when the condition is corrected, and the information message is erased from the display. NBP information messages will remain on the display until the situation is corrected.

The self-test function checks the following components:

• Circuit boards operation (including processor board)

• Reporting of application and operating system revision numbers

• Reporting of internal NBP module software revision number

• TeleMon hardware revision

• Speaker for alarm sounds

•Clock

•Keypad

• Battery charge

• Battery reconditioning

• NBP calibration and use count

• NBP measurement failure messages

If during the power-on self-test you do not hear the alarm sound, turn off the monitor and turn it back on again. If the alarm sound still cannot be heard, contact your service representative.

If during the self-test the battery charge is detected to be below 15%, the monitor will not come up in Monitoring Mode. Instead, the monitor will power off and log a shutdown event in the Event Log. To start the monitor again, insert the AC/DC power cable, or insert a fullycharged battery.

If during self-test the NBP calibration is determined to be invalid, you are forced to enter Service Mode. You cannot enter Monitoring Mode until you complete a valid NBP calibration.

Note—If a message displays on the screen indicating that the battery needs reconditioning,

TeleMon still comes up to monitoring mode. You may continue using the battery if it has enough charge for your monitoring needs. However, the battery should be reconditioned as soon as possible.

If power is interrupted to the TeleMon and it does not have a battery installed, TeleMon’s settings revert to the unit settings.

Diagnostics,

Calibration

Determining When to Perform Calibrations

The NBP calibration should be performed once a year or every 10,000 measurements, whichever comes first. (A measurement count appears on the screen during the self-test after the monitor is first turned on.). If “NBP USE COUNT HIGH” appears, the relative NBP use count is higher than the count limit detected in self-test mode. You must calibrate NBP to remove either of these messages. The calibration procedure is done in Service Mode.

Quick-Check Capability

TeleMon gives you the ability to check the pressure reading before you perform the calibration. To check the pressure reading, you need an adult cuff or a manometer pressure generator (BP bulb), and a T adaptor. You do not need a PC or a transmitter for this procedure.

Use these steps to check the pressure reading.

Step 1. Connect the adult cuff, or manometer to the monitor.

Conducting NBP

Calibration

To conduct the calibration, you will need a manometer pressure generator (BP bulb), and a T adaptor. It’s also recommended that you use an expansion chamber, or an adult cuff applied around a bottle or other object of appropriate size; using an expansion chamber or a cuff makes it easier to stabilize at a given pressure. You will not need a PC or a transmitter to conduct this calibration.

Before you start this calibration, note that you must complete the calibration within three minutes, and that valves release if pressure is over 300 mmHg.

Note—If the calibration fails and you power off TeleMon, you are forced to enter service

mode when you start TeleMon again. You cannot use any monitoring functions until you successfully complete NBP calibration.

Upgrading the Software

TeleMon ships with the appropriate software from the factory. However, it may be necessary to upgrade the monitor’s software while servicing the unit. This section describes how to upgrade the software, for both application and operating system.

TeleMon’s monitoring software and its configuration files are stored separately from the operating system. This setup allows you to upgrade the monitoring software without reprogramming the operating system.

Note—You use the TeleMon Support Tool to upgrade the application software. Therefore, the

TeleMon Support Tool must first be installed on your host computer. Refer to “Installing the TeleMon Support Tool” on page 6-22 for more information.

The required software components for upgrading TeleMon are contained on the TeleMon Installation CD. Those components are:

• TeleMon Application Software (in directory \Telemon Support)

• TeleMon Operating System (in directory \Tm_os)

• Programming tool for programming the Operating System in TeleMon (in directory \OS_Tool)

• Microsoft ActiveSync Connectivity Software (in directory \msasync)

Additionally you will need the following items to upgrade TeleMon:

• A host computer, laptop or desktop, with a free serial port.

Note—If you are using a laptop, it must be plugged into an AC power source to insure

that the processes are not interrupted.

• A synch cable that fits into TeleMon’s upgrade connector, for example an HP F1258A or HP F1223-60901 cable.

• A TeleMon Installation CD.

Getting Started The first step to upgrade TeleMon’s software is setting up the host computer; this includes

installing the TeleMon Support Tool. Once the host computer is setup, and you’ve determined what portion of the software needs to be upgraded, you can proceed with the installation.

Note—TeleMon must be connected to AC power when you are upgrading the software or

operating system.

The following table describes the different software installation procedures described in this section.

Using the Battery Reconditioner

The Battery Reconditioner can be used for charging or reconditioning the TeleMon battery. The reconditioner is an optional accessory.

During normal operating conditions, the battery is recharged while TeleMon is connected to an AC power source. However, over time the battery loses its ability to fully charge. When the battery’s capacity changes by 10% from the last time it was reconditioned, a microchip inside the battery indicates that it needs reconditioning to optimize its performance.

To keep the battery within its optimum capacity range, it’s necessary to recondition it when it loses 10% of its capacity, or approximately after 30 cycles. TeleMon indicates when the battery needs reconditioning during the self-test.

This section describes how to use the reconditioner.

Safety Information

WarningWarning

Certain failure conditions, such as extended short circuiting, can cause a battery to overheat during normal use. High temperatures can cause burns to the patient and/or user, or cause the battery to flame. If TeleMon becomes hot to the touch, unplug the AC power, turn the device off, and place it aside until it cools. Then remove and discard the battery. It’s a good idea to place a piece of tape across the contacts of the battery to prevent inadvertent shorting. Have TeleMon operation checked by service to identify the cause of overheating.

WarningWarning

Failure on the part of the responsible individual hospital or institution employing the use of this equipment to implement a satisfactory maintenance schedule may cause undue equipment failure and possible health hazards.

WarningWarning

If TeleMon is out of antenna range, there is no local indication at TeleMon of this state. No signal will be received at central, and the message NO SIGNAL will be displayed at the central.

WarningWarning

Cycling power repeatedly when the battery is critically low may harm TeleMon or the transmitter. If the battery is critically low, do not attempt to cycle power (reboot) the monitor until the either the battery has been replaced or AC power has been applied.

WarningWarning

Non-supplied accessories and supplies may corrupt the performance of the equipment. Use only EC-12 compliant electrodes with this device. Use of electrodes that are non-compliant may provide erroneous results.

WarningWarning

Some pace pulses can be difficult to reject. When this happens, the pulses are counted as a QRS complex, and could result in an incorrect HR and misdetection of cardiac arrest or some arrhythmias. Keep pacemaker patients under close observation.
