Medicavent Technologies is developing a semi-professional ventilator comprising four primary components: a central control unit, a mixing bag, a patient unit, and flexible tubing.
The central control unit contains a programmable-logic controller, a touch-screen human-machine interface, two inlet valves (oxygen and air), and sensors that enable measurement of pressure, air flow, and oxygen content. This unit acts as both a main control hub and a user interface for the system.
The mixing bag serves as both a pressure reservoir and a mixing tank. It stores the mixture with the required oxygen content and pressure before delivery to the patient, dampening positive and negative pressure shocks to function as a pneumatic capacitor of sorts.
The patient unit, which is placed at the head of the patients bed, contains the inspiratory and expiratory valves, an intrapulmonary pressure sensor, and 22 mm connectors for connecting a dual-limb breathing circuit to the endotracheal tube. The flexible tubing connects the main control unit to the chest unit, and the main control unit to the mixing bag.
