TAKING RECTALTEMPERATURES - RED CAPPED PROBE 1. Exchange the oral probe (blue ejection button) for the rectal probe (red ejection button) by removing the probe from the storage channel, unplugging the probe connector from the thermometer, and repeating steps 1 through 6 in the SETUP section. 2. Attach a probe cover in the same manner as in the oral procedure. Make sure the rEC is displayed. 3. Separate the buttocks with one hand. Using the other hand, gently insert the probe only 1.5 cm (5/8 of an inch) inside the rectal sphincter (less for infants and children). The use of lubricant is optional.
WARNING: Incorrect insertion can cause bowel perforation. Tilt the probe so the tip is touching tissue. Keep hand separating buttocks in place. Hold the probe in place during the entire temperature measurement process. 4. When the final temperature is reached, a tone will sound and the temperature will be displayed. Rectal temperature measurements will take about 15 seconds. 5. After the temperature measurement is complete, remove the probe from the patient, then eject the probe cover by firmly pressing the ejection button on the probe. (Figure 1). 6. Insert the probe into the storage channel to clear the display, in preparation for another temperature. 7. Wash hands (note: washing hands greatly reduces the risk of crosscontamination and NSI).
13
7. Place the arm snugly at the patient’s side. Hold the arm in this position without movement of the arm or probe during the measurement cycle. Movement of the arm or probe during this time will activate the probe position icon and may cause inaccurate readings. 9. An audible tone and display of a temperature reading indicates the final temperature has been reached. 10. After the temperature measurement is complete, remove the probe from the patient’s axilla, then eject the probe cover by firmly pressing the ejection button on the probe (Figure 1). 11. Insert the probe into the storage channel to clear the display, in preparation for taking another temperature.
TAKING AXILLARY TEMPERATURES - BLUE CAPPED PROBE (PATIENTS OVER 4 YEARS THROUGH ADULT) Axillary temperatures for patients 4 years and older should only be taken when the SureTemp is in the Monitor mode using an oral probe. 1. Withdraw the oral probe from its storage channel and observe a quick thermometer display test. 2. Attach a probe cover in the manner as described in step 2 of the OPERATION Section. 3. Place the probe in the axilla and place arm snugly at the patient’s side to reduce the cooling effects of evaporation and convection. 4. After the temperature is displayed, depress the Mode button for more than 2 seconds. The “M” icon will appear on the LCD indicating the unit is in Monitor mode. Continue taking the temperature reading for about 5 minutes. 5. After the Monitor mode temperature has been taken, insert the probe into the storage channel to clear the display and reset the thermometer to Normal mode in preparation for another temperature. 12
INTRODUCTION The Welch Allyn 678 SureTemp is a portable thermistor thermometer to be used for measuring patient temperatures ranging from 84°F to 108°F (28.9°C to 42.2°C). Oral/axillary and rectal probes utilize single-use disposable probe covers which limit cross-contamination. Oral, axillary and rectal temperatures can be taken using Normal or Monitor operating modes. Axillary temperatures taken using the Normal operating mode will display temperatures in about 10 seconds for patients under 4 years. Axillary temperatures for patients 4 years through adult are taken using the Monitor operating mode and will display temperatures in about 5 minutes. In the Normal mode, the thermometer’s microprocessor “predicts” body temperature in about 4 seconds for oral temperatures and in about 15 seconds for rectal temperatures. The Monitor mode continuously displays the temperature of the probe which will reflect the patient’s actual oral or rectal temperature in about 3 minutes and will continue for as long as the probe remains in place.
SAFETY&WARNINGS DO NOT USE IN THE PRESENCE OF FLAMMABLE ANESTHETICS. Caution: Federal (USA) law restricts this device to sale by or on the order of a physician. In order to obtain accurate and reliable temperature-taking results and ensure patient safety, it is important that this booklet be read thoroughly prior to using the instrument. If you have any technical or clinical questions concerning the thermometer’s use and/or care, please contact our Customer Service Department at (800) 854-2904. • Single-use disposable probe covers, available from Welch Allyn, will limit patient cross-contamination. The use of any other probe cover or the failure to use a probe cover may produce temperature errors and will invalidate the instrument’s warranty. • Oral probes (blue ejection button) are to be used for taking oral and axillary temperatures only. Rectal probes (red ejection button) are to be used for taking rectal temperatures only. The use of the wrong probe will produce temperature errors. • The thermometer case is not waterproof; do not drip fluids onto it. • Do not use this instrument for any purpose other than that specified in this booklet. Doing so will invalidate the instrument’s warranty. 1
TAKING AXILLARY TEMPERATURES- BLUE CAPPED PROBE
• Do not use the thermometer if you notice any signs of damage to the probe or instrument. Contact our Customer Service Department for immediate assistance.
(PATIENTS UNDER 4YEARS)
• Do not ETO sterilize without using proper procedures described in the 678 SureTemp technical manual.
Axillary temperature in children ages’ birth through three years can be taken with the SureTemp in the Axillary Mode, with an oral probe.
This unit is equipped with two security alarm systems to reduce theft: • Anti-Theft Temperature Counter System, and • Instant Anti-Theft Audio Alarm System “SEC” is displayed and audio tones are sounded when either alarm system is triggered. The unit is inoperable during this time. The unit must be returned to its wall holder to reset either of these security alarm systems. Refer to the “Changing The Security Setup” section of this manual to set the security feature.
1. Withdraw the oral probe from its storage channel and observe a quick thermometer self-test on the display. 2. With OrL probe type displayed, depress and hold the Mode button for two seconds. ALy will now appear in the display, indicating that the thermometer is ready to take an axillary temperature measurement. Unless the thermometer is in the axillary mode, inaccurate axillary temperature readings will result. Note: The thermometer may be placed in the Axillary mode as the default mode using the Biotech mode, see the Technical Service Manual for further details. When the default mode is set to Axillary, you will not need to press the mode button. 3. Attach a probe cover as described in step 2 of the OPERATION Section. 4. Lift the patient’s arm so that the entire axilla is easily visualized. 5. Place the probe as high as possible in the axilla. Do not allow the probe tip to come into contact with the patient until it is deliberately placed in the measurement site. Any tissue contact before this time will activate the probe position icon and may cause inaccurate temperature readings.

5. After the temperature measurement is complete, remove the probe from the patient, then eject the probe cover by firmly pressing the ejection button on the probe. (Figure 1) 6. Insert the probe into the storage channel to clear the display, in preparation for another temperature.
WALL MOUNTING INSTRUCTIONS The wall mount bracket should be mounted approximately 48 inches from the floor. This allows the end user of average height relatively easy access to the probe and probe covers. It should have at least 12 inches of clearance on the top of the unit so that the end user can easily remove the thermometer probe and load a probe cover without hindrance. Clearance of at least 4 inches from the bottom of the unit and from either side is also advisable to prevent tangling of the probe cord with other equipment at the bedside. The wall mount bracket should be mounted in a location so that when a thermometer is installed, the display can be read from the patient's bedside. Placement should also ensure that the probe can be readily removed from the thermometer, a probe cover can be easily installed and the probe can be returned to its position without stress being placed on either the instrument, the wall mount or most importantly, the patient.
CHANGING THE SECURITY SETUP The SureTemp Model 678 is equipped with a security option that is designed to reduce the possibility of theft.
USINGTHE MONITOR MODE
To change the security options, you must first enter the Biotech mode.
Remove the probe from the storage channel and take a temperature using Oral, Rectal, or Axillary Mode. After the temperature is displayed, depress the Mode button for more than 2 seconds. The “M” icon will appear on the LCD indicating the unit is in Monitor mode. The unit is ready to continuously display temperatures in Monitor mode. After the Monitor mode temperature has been taken, replacing the probe in the storage channel clears the display and resets the thermometer to Normal mode. The unit will automatically enter the Monitor mode by removing the probe from the probe storage channel and waiting 60 seconds.
Entering the Biotech Mode
NOTE: When using the Monitor mode, allow the temperature readout to stabilize for 3 minutes for oral and rectal temperatures and 5 minutes for axillary temperatures.
• Place the unit into the wall holder. • Press and hold the mode button while removing the probe from the probe holder. You are now in the Biotech Mode. • Remove the thermometer from the wall holder. Note: Replacing the probe into the probe holder will place the thermometer back into its normal operating state. Once in the Biotech Mode, there are several functions that can be accessed. These function are described completely in the Model 678 Technical Manual. The following section describes the security functions only.

Setting the Security Feature In the Biotech Mode, you will need to step through the various Biotech functions until you reach the functions that apply to the security modes. To step through the Biotech functions, press and hold the Mode button for approximately 2 seconds until the function number changes and a double beep is heard. The function number of the currently displayed function is displayed in the lower right hand corner of the display.
OPERATION 1. Withdraw the probe from the storage channel and observe a thermometer display test followed by an audible tone and a display of the probe type OrL = Oral, ALy=Axillary, or rEC = Rectal.
Once the Biotech function number has been changed, release the Mode button. Once the desired function number is reached, press and immediately release the Mode button to toggle the settings within the function. The security-related functions are as follows: • Function 5: Temperature Count Security Feature The displayed number indicates the number of temperatures that can be taken before the unit goes into security alarm mode and must be returned to the security wall holder. The counts are 0, 25, 50, 100 and 200 and appear sequentially. If the count is set to “0”, the temperature count function is disabled or turned off and no security alarm will occur regardless of the number of temperatures taken. This function is independent of function 6 which is the instant-on security feature.
2. Load a probe cover onto the probe. Hold probe handle collar with thumb and forefinger, being careful not to hold or press the “ejection” button. Press the collar down firmly to secure the cover.
TAKING ORALTEMPERATURES - BLUE CAPPED PROBE The ability of the 678 SureTemp to take an accurate oral temperature in about 4 seconds requires correct user technique.
• Function 6: Instant-On Security Feature
1. With OrL showing on the display, insert the probe tip gently into the patient’s slightly opened mouth. Quickly slide the probe under the tongue on either side of the mouth to reach the sublingual pocket. Have the patient close his/her lips around the probe.
With this function set to ON, the thermometer immediately goes into security alarm when removed from the security wall holder. The options here are on and off. In the “OFF” setting, the unit will not alarm when removed from the wall holder.
2. Hold the probe in place, keeping the tip in contact with tissue during the entire temperature measurement process. Holding the probe still will ensure a fast and accurate measurement.
