This Clinical study is preformed in order to estimate the performance of the TMS thermometer and to make a final tuning of the thermometer mathematical algorithm.

Body temperature of men, women and children will be measured using the TMS thermometer.

Each Patient will be measured both with the TMS thermometer and with an esophageal or urinal thermometer as a reference.

Condition Intervention
to Evaluate the Performance of the TMS Thermometer and
Improve Its Algorithm
Device: Intraoperative temperature measurement by TMS thermometer
Device: Esophageal or urinary bladder temperature measurement

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Clinical Evaluation of TMS (Temperature Monitoring System) Performance

Further study details as provided by Rambam Health Care Campus:

Primary Outcome Measures:
  • Correlation between TMS and the esophageal/urinary temperature measurements [ Time Frame: The results of this study will be presented in 6 months from today (an average) ]
    TMS will track patient's temperature during the operation concurrently with esophageal and/or urinary temperature sensor. Correlation will be calculated between both temperature measurement methods and tracking ability of the changes in patient's temperature during the operation will be compared.

Estimated Enrollment: 500
Study Start Date: April 2008
Estimated Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Intraoperative temperature measurement by TMS thermometer
    Measurements will be taken from the patient's body using a biocompatible patch that will transfer data to the receiving unit. The patch will be sterilized before each surgery.
    Device: Esophageal or urinary bladder temperature measurement
    Standard temperature measurement as is being measured from patients during surgery today
Detailed Description:

Temperature measurement is vital during surgery. Accurate temperature reading can indicate patient's condition and alarm if something is wrong.

Nowadays, during surgeries temperature is measured mostly using an esophageal or a urinal thermometer, both of which are invasive, therefore they complicate the procedure and require time and activity of the medical stuff.

The TMS thermometer combines a noninvasive, biocompatible patch, which is attached to the body, and a receiving unit, which is placed near the body or the vital signs monitors and receives data from the patch. There is no connection between the body and the receiving unit. The measurement is based on a conductive sensor that measures the skin temperature and applies special algorithm in order to calculate the core body temperature.

The purpose of this clinical study is to evaluate the performance of the TMS thermometer and improve its algorithm by comparing its measurement to the esophageal or urinal temperature measurement
