Area of Science:

  • Biomedical Engineering
  • Medical Devices
  • Clinical Thermometry

Background:

  • Traditional electronic thermometers often rely on cables, limiting patient mobility and posing infection control challenges.
  • Wireless temperature monitoring systems are needed to enhance patient comfort and streamline clinical workflows.

Purpose of the Study:

  • To describe a novel wireless electronic clinical thermometer system.
  • To demonstrate its capability for simultaneous, cable-free temperature logging.

Main Methods:

  • Development of a battery-powered wireless sensor for individual patients.
  • Utilization of a hand-held interrogating device for data acquisition.
  • Implementation of radiofrequency-tuned circuit coupling for wireless communication.

Main Results:

  • The system allows for cable-free temperature measurement between sensor and indicator.
  • Virtually instantaneous temperature readouts are achieved.
  • No interference is observed between adjacent users, enabling simultaneous monitoring.

Conclusions:

  • The described wireless electronic thermometer offers a practical solution for efficient and non-invasive patient temperature monitoring.
  • Its design facilitates improved patient care through enhanced mobility and reduced infection risk.
