About Transceivers

Wireless Medical Telemetry Services (WMTS) Remote Transceivers provide the link

between the patient and the Central Station through the newly approved 608 - 614

MHz Medical Telemetry frequency band. The ambulatory and bedside device trans-

ceivers communicate data to the Central Station through the Access Point transceiver.

In addition, the transceivers are capable of receiving control commands for self-use or

connection transfer.

The PatientNet ambulatory transceiver is the DT-4500. This transceiver is worn by the

patient and usually carried in a gown pocket or pouch, and used with a 3, 4, or 5-wire

leadset connected to the electrodes on the patient. The DT-4500 is IPX7 compliant, so

it can be submerged in 1m of water for up to 30 minutes.

The DT-7000 and DT-7001 are the PatientNet bedside-device transceivers and are

physically connected to bedside monitors (other manufacturers’ bedside monitors and

NPB 7200 series ventilator).

The DR-10000 Access Point transceiver collects data from the ambulatory and bed-

side transceivers, sends that data to the Central Station, and transmits control data to

the transceiver devices.

WARNING: Remove transceivers from patients before MRI and CAT scan procedures, and

store the transceivers outside the room where such equipment is located.

Close proximity to MRI or CAT scan equipment may result in damage to

transceivers.

Programming Transceivers

Before a transceiver can be used with the PatientNet System, it must first be pro-

grammed with a Network Number and Monitor I.D. number to match the correspond-

ing Central Station. Consult your facility’s system administrator to perform these

functions.

WARNING: When programming the DT-4500 through the External Serial Device (I/O) con-

nector, it must be disconnected from the patient. The accessory connector

shall be kept covered when not in use with the supplied protective cover.

Failure to follow these instructions could lead to excessive voltages and cur-

rents being applied to the patient, resulting in cardiac arrest.

The corresponding Central Station must also be programmed to this Network Number

and Monitor Identification number.

If you have any questions about the programming status, contact your system adminis-

trator.

WMTS TRANSCEIVERS Displaying Transceiver Status You can view transceiver status on the Central Station, but not on the PatientNet Viewers (also known as the IRVS and RVS). 1. Press System on the Main screen. 2. Press OpenNet button on the Passcode screen to display the OpenNet Status screen (fig. 90). Fig. 90. OpenNet Status screen Your System Administrator enables or disables the Assign TX, Program AT, and Program IT buttons. Check with your System Administrator for more information.

WMTS TRANSCEIVERS Impedance Values The DT-4500 Ambulatory Transceivers electrode impedance values, which are displayed on the OpenNet Transceiver Status screen, indicate the quality of the signal connection and are not the actual impedance values that are measured by the system. The electrode impedance values range from 100 to 200 (optimal). The typical values range between 180 and 200. If the electrode’s impedance value is greater than the defined Quality Threshold value, then its LED is illuminated.

WMTS TRANSCEIVERS 7. The DT-7000/DT-7001 is not designed as a patient contact device. Per FCC rules, the DT-7000/DT-7001 must reside more than 20 cm (7.9 inches) from the patient. Cautions 1. Any changes or modifications to the device that are not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. 2. Electromagnetic interference or power overload, due to electrosurgical or diathermy instruments, may damage the device. Notes 1.

WMTS TRANSCEIVERS Ambulatory Transceiver (DT-4500) The DT-4500 transceiver is a battery-operated ambulatory transceiver worn by the patient and used with a 3, 4, or 5-wire leadset that is connected to electrodes on the patient. The transceiver is available to patients who are not confined to a bed, but still require constant monitoring of their ECG waveforms. Operating Instructions Push Button Function and Use See Figure 91 on page 190 for an image of the DT-4500 controls and LED indicators.

WMTS TRANSCEIVERS Attendant Present / Procedure Alarm Silence (PAS) Unlock Button The Attendant Present/PAS Unlock Buttons consists of two buttons that are located on either side of the transceiver (See Figure 91 on page 190). The Attendant Present push buttons have three functions. Each function is initiated based on how long the buttons are pressed. 1. Lead Quality Pressing both Attendant Present buttons simultaneously will illuminate the LEDs for each lead that has a minimum level of quality. 2.

WMTS TRANSCEIVERS Procedure Alarm Silence (PAS) Button Depressing the PAS button, while the PAS Status Indicator LED is flashing, informs the clinicians at the Central Station area that the attending nurse will be performing a procedure to the patient that may cause inadvertent false alarms at the Central Station (i.e. changing lead wires, electrodes, etc.) Once the PAS button is pressed, the following events occur at the Central Station. 1.

WMTS TRANSCEIVERS LED Indicators Function Upon Power-On, all LED indicators are illuminated for a brief period. After the specified time period, only those LEDs displaying positive (or negative) transceiver functions, as described in each section below, remain illuminated. Procedure Alarm Silence Status Indicator The Procedure Alarm Silence Status Indicator is illuminated when the PAS function is active.
PAGE 10
WMTS TRANSCEIVERS The Quality Threshold value has a default setting. If the electrode’s impedance value is greater than the default, then its LED is illuminated. The DT-4500 stores the Quality Threshold value and uses this value to determine whether or not the electrode LED should be illuminated when the Attendant Present buttons are pressed. See “Impedance Values” on page 185 for details.

WMTS TRANSCEIVERS Cleaning This section provides cleaning and maintenance instructions for DT-4500 transceivers. Read and follow all precautions when cleaning transceivers. WARNING: No claims are made concerning the sterility of the DT-4500 Ambulatory Transceivers. CAUTION: Do not sterilize any part of the transceivers. Gas sterilization, autoclaving, liquid immersion, and other sterilization methods can cause serious damage to the devices that may not be obvious to the user.
PAGE 12
WMTS TRANSCEIVERS Note: Once a month, or whenever the DT-4500 is submersed or subjected to a stream of liquid, remove the accessory connector cover and remove any moisture that may have collected inside. Cleaning the Battery Compartment CAUTION: When cleaning the battery compartment, use only soap, water, or alcohol. Do not use any other cleaning agents inside the battery compartment as they may damage the battery compartment.
PAGE 13
WMTS TRANSCEIVERS Cleaning 1. Wipe the leadset with a solution of soap and water. 2. Use a cloth moistened with distilled water to rinse away the cleaning solution. 3. Dry thoroughly with a lint-free cloth. Disinfecting Use hospital-approved disinfecting procedures such as those recommended by AAMI or AORN. 1. Wipe the leadset with a fresh 10% solution of chlorine bleach and water or a 2% gluteraldehyde solution such as Cidex. 2.

WMTS TRANSCEIVERS Installing and Removing a Battery See “Specifications” on page 247 for acceptable batteries. Note: Battery service life can be substantially improved by using nine-volt lithium batteries. To install a 9V transceiver battery, first open the transceiver battery compartment by placing your thumb and forefinger on the compartment latch and flipping it open.

WMTS TRANSCEIVERS Instrument Transceiver (DT-7000, DT-7001) WARNING: When using a bedside device with the instrument transceiver (DT-7000/7001), the bedside device is the primary monitor and alarm source. Disabling alarms on the bedside device is not safe clinical practice. The DT-7000 and DT-70011 send data and alarm information from bedside monitors and NPB 7200 series ventilators to the Central Station. The transceivers support the bedside monitors shown in the PatientNet Customer Release Notes.

WMTS TRANSCEIVERS Use and Maintenance Connecting to the Bedside Monitor See Figure 92 on page 200 for an image of the DT-7000/DT-7001 controls and LED indicators. Note: Before the transceiver is connected to the bedside monitor, the system administrator must program it with the bedside device specific software module. 1. Attach the transceiver to the bedside monitor by sliding the Device Hook over the Mounting Disk until the transceiver snaps into place.
