Novel CAM Mechanism-Based Life-Support Ventilators in Animal Healthcare

Mechanical ventilation is a way of providing respiratory support for animals which are unable to breathe or oxygenate on their own. It is used for a wide variety of conditions and situations. A mechanical ventilator does not cure any disease or conditions but aids in the function of treatment by supporting the process of respiration. The ventilators must also work with high level of accuracy, as even a small mistake can cost a life. The existing ventilators in the field remain expensive, making it inaccessible to small-scale hospitals, and further a demand for a simplified yet effective ventilator always exists. This project deals with the development of an alternate low-cost electronically controlled stand-alone mechanical system to effectively control the rate and waveform of air in animal life-support ventilator systems. The Frustum CAM (FC) mechanism—a first of its kind, patented mechanism which uses the concept of Variable Valve Lift (VVL) to control the lift of valve, thereby controlling the flow rate of air. By effectively developing the FC ventilator system or by integrating it to the conventional ventilators using proper supporting system, the cost can be cut down to a great extent and yet high flow control can be achieved.
