A gas filter device for a medical device that provides a gas to a patient including first and second gas filter elements; a body defining a cavity receives the first and second gas filter elements in series and spaced apart from, each other; first and second end walls at opposites ends of the cavity; a first coupler extending from the first end wall; a second coupler extending from the second end wall, wherein the first coupler and the second coupler define a flow channel in communication with the cavity.

Dual membrane bacterial viral filter and method of operation thereof

A method for controlling a ventilator includes the steps of providing an inhalation pressure limit, determining when a pressure in a connection to a patient circuit is greater than the inhalation pressure limit, and opening the valve when the pressure is greater than the inhalation pressure limit. An associated computer readable medium for controlling the method is also described.

Active valve for ventilators

A ventilator includes a first pathway configured to supply a first gas; a second pathway configured to supply a second gas; a bypass element configured to provide a portion of the first gas and a portion of the second gas, the bypass element comprising a rib adjacent to a bypass conduit, wherein fluid flow is substantially laminar adjacent to the conduit. A bypass element is described.

Bypass flow element for diverter flow measurement

Systems and methods for mixing at least two gases for delivery to the airway of a subject use a gas mixing circuit having a diffusion portion. The diffusion portion may be configured to elongate the shape of the cross-section of the path through the gas mixing circuit in a particular direction and/or orientation. As a result, the gas concentration profile of the gas mixture after the gas mixing circuit is more uniform than the gas concentration profile after the merging of multiple gases.

Respiratory therapy systems and methods using a gas mixing circuit

A valve () for controlling pressure in a ventilation system. The valve includes an electromagnet (), a shaft () connected to the electromagnet, and a diaphragm () connected to the shaft, wherein the electromagnet applies force to the diaphragm based on an input. The ventilation system includes a ventilator () connected to a patient circuit (), the valve () controlling pressure in the ventilation system, and a controller () connected to the valve and configured to provide the input to the valve.
