Temperature Measurement Sites

1.6K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Area of Science:

  • Biomedical Engineering
  • Wearable Technology
  • Sensor Systems

Background:

  • Diabetic foot ulceration poses a significant health risk, necessitating continuous monitoring.
  • Existing monitoring systems often require external power sources, limiting their practicality.
  • Wireless sensor platforms offer potential for remote patient monitoring.

Purpose of the Study:

  • To develop a self-powered wireless temperature sensor platform for diabetic foot ulcer monitoring.
  • To investigate the energy harvesting capabilities of piezoelectric materials for powering the sensor.
  • To evaluate the performance and efficiency of the developed sensor prototype.

Main Methods:

  • A sensor platform integrating a piezoelectric bimorph for energy harvesting, a power conditioning circuit, a temperature sensor readout, and a wireless module was designed.
  • The energy requirement for data transmission was calculated (4.826 mJ per 18-byte packet).
  • Prototype evaluation involved five subjects with varying weights and foot shapes during walking.

Main Results:

  • The piezoelectric bimorph effectively converted foot movement into electrical energy to power the sensor.
  • Average walking times to transmit data packets were 119.6 s for the first and 71.2 s for subsequent packets.
  • The temperature sensor achieved a resolution of 0.1 °C and a sensitivity of 56.7 mV/°C, with 74.5% power conditioning efficiency.

Conclusions:

  • The self-powered wireless temperature sensor platform is a viable solution for diabetic foot ulcer monitoring.
  • The system demonstrates efficient energy harvesting from natural foot movements.
  • This technology can enable continuous, non-invasive monitoring, potentially improving patient outcomes.
