Latest Patents

Stewart's latest patents include innovative designs for respiratory devices. The first patent describes a respirator that utilizes a plurality of pneumatic bistable elements in an automatically operated pneumatic circuit. This design features a constant inspiratory to expiratory ratio, simplifying respirator control. A demand sensing circuit is integrated to initiate the inspiratory phase in response to pressure changes in the patient gas supply circuit. Additionally, a manual control allows for manual dispensing of respiratory support, while a pneumatic circuit generates an end inspiratory plateau period for gas equilibration in the lungs.

The second patent focuses on a pediatric respirator that employs pneumatic elements to create various operating modes. This device allows a gas mixture to be supplied through a patient connection, which is then controllably exhausted to the atmosphere via an exhaust port regulated by a control valve. The control valve manages the closure of the exhaust port to facilitate inspiration and expiration control. The use of pneumatic logic elements enables automatic support for different breathing modes, such as volume-limited or pressure-limited, enhancing the versatility of the device.
