Transdermal Patient Monitoring

This non-invasive reverse iontophoresis (RI) based transdermal patient monitoring technology is capable of detecting and measuring, either intermittently or continuously, one or more small molecules, e.g. glucose and lactate, in real time. The technique works by extracting small molecules, such as glucose and lactate, from the patient using a small gel electrode situated on the patient’s skin.
The technology was developed originally as part of a PhD project. This was followed by an Eng. D project in the University’s Medical Devices Doctoral Training Centre and resulted in a fully programmable well developed RI device to which screen printed, gel coated electrodes, applicable to patient skin, were attached. Preliminary studies in human volunteers looking at glucose and lactate detection/measurement suggested that the device could accurately and reproducibly detect glucose through the skin. The skin electrode/biosensor system will soon be capable of detecting and measuring glucose and lactate in real time.

Key Benefits

Increased convenience due to non-invasive nature of the device
Portable
Extracts a number of blood circulating molecules for a wide variety of analytical uses
Will aid more successful monitoring due to increased patient compliance gained through the reduced need for painful injections
Home, clinic and hospital based applicability

Applications

Glucose monitoring markets - home & hospital testing
Since the device is programmable and multiparameter it has the capability to extract a number of other blood analytes, e.g. lactate for sports applications, therefore the market for such a device is extremely broad
The device has the potential to be used in a reverse mode for drug delivery applications
