A robotic lower limb prosthesis is an active device that replaces all or a part of the lower extremity. It provides the amputee the opportunity to perform functional tasks, particularly ambulation (walking), which may not be possible without the limb. The design of the prosthesis is depend on the functional level of the amputee and it is geared toward comfort.

Positive-pressure ventilation is used when a patient's spontaneous ventilation is inadequate to maintain life. Positive-pressure ventilators supply air or a mixture of air and oxygen under possitive pressure to the patient's trachea (the airway) through an endotracheal tube (flexible plastic tube that is put in the mouth or nose and then down into the trachea.). The positive pressure causes the gas to flow into the lungs

Prostheses play a significant role on providing the amputees the independency, enabling them to restore the lost body functions caused by their amputation. Recent developments in robotics and bio-medical signal processing has greatly influenced on such kind of assistive technologies to achieve tremendous performance capabilities over the available traditional assistive technologies. Accordingly, the development of the robotic prosthetic systems has become and emerging research interest among the researchers. As a country in its post war era, Sri Lanka also bear a larger community of amputees

Exoskeleton robot is kind of a man-machine combination in which the intelligence largely depends on human. The limitations in Artificial Intelligence (AI) can be overcome in these systems. It combines the human intelligence and the machine power so that the combined system enhances the intelligence of the machine and also the power of the human operator. As a result, the human operator can achieve what is not capable himself. Exoskeleton robots are used for power augmentation, motion assist, rehabilitation or virtual reality applications. In each of these application domains, the particular robots inherit

The healing rate of a wound can be increased by applying a controlled negative pressure externally. This treatment method is known as negative pressure wound therapy (NPWT). NPWT can be used for treating wounds which usually take a long time to heal or do not heal at all when treated using conventional treatment methods. International organizations have already developed NPWT machines, but due to their high cost, only a limited number of machines are available in Sri Lanka.
