INDICATOR TEMPERATURE COMPENSATION IN FLOW RATE CALCULATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240032811 titled 'INDICATOR TEMPERATURE COMPENSATION IN FLOW RATE CALCULATION

Simplified Explanation

The abstract describes a catheter and introducer sheath assembly that is used to measure flow rate in a conduit using dilution methods. The catheter and sheath are aligned in a predetermined manner, allowing an indicator to be introduced into the flow to be measured. The temperature of the indicator is determined by extrapolating or estimating from the temperature curve recorded by a sensor on the catheter and the known thermal properties of the sensor, catheter, or both. The flow rate in the conduit is then estimated based on the area of the dilution bolus and the return to baseline of the dilution bolus.

  • The catheter and introducer sheath assembly is designed to measure flow rate in a conduit using dilution methods.
  • The assembly allows for the introduction of an indicator into the flow to be measured.
  • The temperature of the indicator is determined by analyzing the temperature curve recorded by a sensor on the catheter.
  • The thermal properties of the sensor, catheter, or both are used to estimate the indicator temperature.
  • The flow rate in the conduit is estimated based on the area of the dilution bolus and the return to baseline of the dilution bolus.

Potential Applications:

  • Medical procedures requiring accurate measurement of flow rate in a conduit, such as blood flow in arteries or veins.
  • Monitoring and managing fluid flow in industrial processes.

Problems Solved:

  • Provides a method for accurately measuring flow rate in a conduit using dilution methods.
  • Eliminates the need for invasive or more complex flow measurement techniques.
  • Allows for real-time monitoring and measurement of flow rate.

Benefits:

  • Non-invasive and minimally invasive method for measuring flow rate.
  • Provides accurate and real-time flow rate measurements.
  • Simplifies the process of flow rate measurement in medical and industrial applications.


Original Abstract Submitted

a catheter and introducer sheath assembly is provided for measuring a flow rate in a conduit by dilution methods. the catheter is configured to engage the introducer sheath in a predetermined alignment, where an indicator is passed through a volume defined by an exterior of the catheter and an interior of the introducer sheath to be introduced into the flow to be measured. the determination of the indicator temperature is extrapolated or estimated from (i) an observed temperature curve of an indicator sensor on the catheter that records a substitution of warmed fluid in the sheath by the introduced indicator and (ii) a pre-examined, predetermined or identified thermal properties or characteristics of the sensor, the catheter, or the sensor and catheter. the determination of the flow rate in the conduit is estimated using (i) the area of the dilution bolus and (ii) the return to baseline of the dilution bolus.
