Principle of operation
FloRight is based on proprietary technologies related to volumetric physiological measuring systems and methods, using electromagnetic induction techniques.
Device details and safety
Like all medical devices, our products must be developed, produced and marketed in accordance with applicable regulations and approval procedures.
Respiratory measurements are derived from changes in electromagnetic inductance in a wrap-around vest. The vest is disposable and should be used by one patient only. The vest is of a soft, elastic and allergy-tested material (cotton and Lycra) evaluated according to ISO10993 and provided in several sizes appropriate for the neonatal patient population.
The vests contain thin conductive coils that are isolated. Thorax volumes and volume changes are measured and depicted on a display which is also a touch screen interface to operate the device. The measurements are stored digitally by the device for any later review and comparison needs.
A weak, homogeneous magnetic field is created in the spatial region occupied by the patient torso. Magnetic noise from surrounding systems are factored in by means of a calibration procedure before each measurement. The magnetic field that is created is homogeneous across the bed, which prevents limited patient movements from impacting resumed measurements. This magnetic field is in the same order of magnitude as the magnetism of the earth. Radiation from the system is low, comparable to the level a few meters away from a traditional television set. A weak alternating current and very low voltage is applied.
Some generalisations were made here for brevity.
