ATTENTIV: Instrumented Peripheral Catheter for the Detection of Catheter Dislodgement in IV Infiltration

Area of Science:

• Biomedical Engineering
• Medical Devices
• Clinical Monitoring

Background:

• Intravenous (IV) infiltration is a frequent complication of IV infusion therapy.
• Leakage of IV fluids can lead to swelling and severe tissue damage.
• Current methods lack continuous, real-time monitoring, particularly for critically ill patients.

Purpose of the Study:

• To design and verify a sensor-integrated catheter for early detection of IV infiltration.
• To address the need for continuous, automated monitoring solutions in clinical settings.

Main Methods:

• Development of the ATTENTIV catheter with integrated sensors for direct detection of catheter dislodgement.
• Verification of two detection methods: support vector machine for blood-tissue differentiation and a thresholding algorithm for signal peak identification.
• Utilizing bioimpedance as the sensing modality for preliminary testing on biological and phantom models.

Main Results:

• Promising preliminary testing results were achieved on biological and phantom models.
• The sensor-embedded catheter demonstrated effective detection capabilities.
• The study verified the feasibility of bioimpedance for sensing IV infiltration.

Conclusions:

• The sensor-embedded ATTENTIV catheter shows potential for automated IV infiltration detection.
• This technology could replace traditional infusion catheters and manual detection methods.
• The ATTENTIV catheter offers a promising solution for improving patient safety during IV therapy.
