Remote oximetry device
The remote oximetry device provides an affordable and convenient method to conduct sleep studies. The device allows clinicians to remotely monitor blood oxygen levels in risk patients during the course of a night’s sleep.

The device is intended for use as a screening tool in non-specialist hospitals in any location, and will provide a secure internet link between a standard pulse oximeter (which measures blood oxygen saturation) and a computer monitoring the study remotely.

Wave Instruments has been working closely with the Mater Children’s Hospital in Brisbane to assess the clinical validity of remote health monitoring.  A prototype has been developed and is currently being trialled in conjunction with the Hospital.

ECG / Holter monitor
A portable ECG monitor, this device can be used to predict the onset of heart problems. The monitor, records and analyses heart rate data to predict the onset of life-threatening cardiac arrhythmias.

The analysis method for the devices is based on chaotic mathematics, in which ECG data is used to identify trends indicating an increased likelihood of ventricular arrhythmia (a major cause of cardiac arrest). The method uses the beat-to-beat interval of the ECG as an input to the algorithm, and is expected to be able to detect changes two to five minutes prior to onset of ventricular fibrillation, providing a time window in which preventive action can be taken. The method can be enabled in ambulatory, implanted or static monitoring devices.

An ambulatory prototype device has been developed, clinical ethics approval granted and clinical collaborators at The Prince Charles Hospital in Brisbane have assisted in the initial development.

Static magnetic field dosimeter
Wave Instruments is developing the world’s first range of personal dosimeters to monitor workers exposed to static and electromagnetic (EM) fields.

An initial prototype has been developed and trialled for static field dosimetry. The device has been shown to be electromagnetically compatible and capable of accurate field logging at strengths of up to four Tesla.

Future prototypes capable of logging low frequency and high frequency electromagnetic fields also will be developed.

Cardiac mapping system
Our integrated cardiac mapping system, allows clinicians to easily monitor the placement of pacemaker and other catheters in the heart.

Intracardiac wires or leads are implanted in patients on a daily basis for pacemakers, indwelling defibrillators and to destroy aberrant conduction pathways in the heart. The insertion of catheters often requires hours of exposure to x-rays to determine the exact position of the catheter.

In this project, individual structural and electrophysiological models of the heart of a patient are generated from 3D MRI scans and an electrophysiological model developed. When combined with a body surface potential map, a catheter tracking system personalised to each patient can be developed, potentially improving treatment outcomes and reducing x-ray exposure to both patient and clinician.

This is an early stage project and will require significant further development effort. The model for prediction of potential distributions on the surface of the heart is complete, and further development will focus on measurement of body surface potentials and predictive localising of catheters and/or other sources.
