## Indications for Use

The Welch Allyn SureTemp® Plus thermometer enables the health care professional to make an accurate prediction of a febrile or hypothermic patient's oral temperature in approximately 4-6 seconds (in Normal mode). Pediatric Axillary (age 17 and younger) temperatures can be obtained in approximately 10-13 seconds. Adult Axillary temperatures (in Normal mode) can be obtained in approximately 12-15 seconds. Rectal temperatures (in Normal mode) can be obtained in approximately 10-13 seconds. Normal (predictive) mode is available for oral, rectal, and axillary use. In the Monitor mode, the instrument provides the capability of accurate, long-term monitoring of actual oral, rectal or axillary temperature, and of following the temperature whether constant, increasing, or decreasing. The SureTemp is a clinical grade thermometer intended for use by healthcare practitioners only; typically in a hospital, clinic, long- term care, or mobile health care environment. It is not intended for home use.

## Device Story

SureTemp Plus is a clinical electronic thermometer; consists of elongated metal heat-conductive probe with internal thermistor connected to main body via coiled cord. Used by healthcare practitioners in hospitals, clinics, or long-term care facilities. Operation requires disposable plastic probe cover to prevent cross-contamination. Device functions in two modes: Normal (predictive) and Monitor (continuous). In Normal mode, algorithms process thermistor signals to predict final temperature within 4-15 seconds. In Monitor mode, device tracks actual temperature changes over time. Output displayed on screen; Model 692 includes backlit display, security features, and pulse timer; Model 690 is lower-cost version without these features. Provides rapid, accurate temperature assessment to assist clinical decision-making regarding patient febrile or hypothermic status.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Electronic thermometer; thermistor-based sensing; predictive and continuous monitoring modes; elongated metal probe; disposable plastic probe covers; Model 692 includes backlit display, security features, and pulse timer; Model 690 lacks these features; powered by main body unit.

## Regulatory Identification

A clinical electronic thermometer is a device used to measure the body temperature of a patient by means of a transducer coupled with an electronic signal amplification, conditioning, and display unit. The transducer may be in a detachable probe with or without a disposable cover.

## Special Controls

(1) Device is not a clinical thermometer with telethermographic functions; 
(2) Device is not a clinical thermometer with continuous temperature measurement functions; and 
(3) Appropriate analysis and testing (such as that outlined in the currently FDA-recognized editions, as appropriate, of ISO 80601-2-56, “Medical electrical equipment—Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement,” or ASTM E1965, “Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature,” or ASTM E1112, “Standard Specification for Electronic Thermometer for Intermittent Determination of Patient Temperature,” or ASTM E1104, “Standard Specification for Clinical Thermometer Probe Covers and Sheaths”) must validate specifications and performance of the device.

## Predicate Devices

The SureTemp® Plus clinical electronic thermometer consists of an elongated metal heat-conductive probe connected to the thermometer's main body through a coiled cord. The probe contains a thermistor that conveys temperature information to the main body for calculation of patient temperature.

Prior to use, a plastic probe cover must cover the probe. This cover must not be a significant barrier to the transfer of heat from the patient to the probe body (and thermistor). In addition, the disposable nature of the probe cover prevents microbiological cross-contamination amonq patients which might occur with a reuseable probe. Calculation of patient temperature may (in the normal or predictive mode) utilize algorithms that enable accurate temperature prediction within 4 to 15 seconds of probe placement (times vary based on the temperature mode selected).

There are two model designations for the SureTemp® Plus and they are the Model 692 and 690. The Model 690 is the lower cost version of the Model 692 and does not include the backlit display and security features or pulse timer.

# Device Description

The SureTemp® Plus clinical electronic thermometer consists of an elongated metal heat-conductive probe connected to the thermometer's main body through a coiled cord. The probe contains a thermistor that conveys temperature information to the main body for calculation of patient temperature.

Prior to use, a plastic probe cover must cover the probe. This cover must not be a significant barrier to the transfer of heat from the patient to the probe body (and thermistor). In addition, the disposable nature of the probe cover prevents microbiological cross-contamination among patients which might occur with a reuseable probe. Calculation of patient temperature may (in the normal or predictive mode) utilize algorithms that enable accurate temperature prediction within 4 to 15 seconds of probe placement (times vary based on the temperature mode selected).

There are two model designations for the SureTemp® Plus and they are the Model 692 and 690. The Model 690 is the lower cost version of the Model 692 and does not include the backlit display and security features or pulse timer.
