Overview
Extravasation injury occurs when peripheral intravenous (IV) medication accidentally leaks from the vein, causing the skin to form a bump and damage to the surrounding cells. Children, neonates, and elderly are prone to IV injuries because of their small or fragile veins. Available devices to detect extravasation are expensive, bulky, and not for routine use. The use of vein visualization devices also does not guarantee detection of extravasation injury.
Our conformal sensor patch can be universally applied to all patients requiring IV therapy to rapidly detect and prevent extravasations injuries. The piezoresistive nature of the sensor detects extravasation when the electrode is stretched. The sensor patch comes with a wireless circuit module that filters-out signal noise, perform continuous recording, and automatically sends alert of extravasation to clinical staff. This facilitates prompt clinical intervention that prevents adverse effect of extravasation.
TECHNOLOGY FEATURES & SPECIFICATIONS
• The sensor patch is ultra-sensitive at >40% resistance change at 2ml infused volume
• The solution does not discriminate the type or opacity properties of IV fluid
• The solution is independent of IV infusion rate
• The sensor patch is disposable, and the cost is competitively cheap
• The wireless monitoring system uses a reusable external circuit module which can transmit data to a tablet reader hub via Bluetooth
• The wireless monitoring system is able to send push notifications to clinical staff’s smartphone
POTENTIAL APPLICATIONS
