DESIGN OF COST AND SIZE EFFECTIVE VENTILATOR WITH CAM SHAFT MECHANISM

A ventilator is a device that delivers air into and out of the lungs in order to provide breaths to a patient who is unable to breathe in normally or is breathing insufficiently, and are used in a multitude of medical fields, as in ambulatory services, the ICU, and for patients of respiratory disorders. The ventilator delivers artificial breaths to the lungs of the patient via the oro- nasal cavity with a range of 10-30 breaths per minute, and may vary with a number of determining factors, and aims to match the normal time duration for inhalation to exhalation ratio. In comparison to conventional ventilators, the design in discussion aims to improve the functioning by increasing power efficiency, adding alternating sources of power, and making a compact design. Cost effectiveness is aimed as one of the priorities, by adding a motorized camshaft mechanism for automation, to rhythmically compress a silicon ventilation bag in order to achieve the desired results. The whole system is also designed to monitor other critical data of the user, such as their exhalation pressure, blood oxygen and glucose levels and displays the results on a mini screen. Included within is an emergency alert system with a buzzer for indication if the vitals of the patient are at a critical state. The entire system is driven by a controller circuitry to achieve desired results and to assist patients and in other emergency situations.
