Humidifier bypass valve

摘要

A valve (30) for controlling a flow of fluid, the valve having a conduit, first valve portion having an inlet, a first humidifier interface, and a first conduit opening to the conduit. The first valve portion defines a switchable flow path between the inlet and either the first humidifier interface or the first conduit opening. A second valve portion has an outlet, a second humidifier interface, and a second conduit opening to the conduit. The second valve portion defines a switchable flow path between the outlet and either the second humidifier interface or the second conduit opening. Responsive to the first and/or second humidifier interfaces being connected to a humidifier chamber, the fluid flows from the inlet to the outlet through the humidifier chamber, and responsive to the first and second humidifier interfaces being disconnected from the humidifier chamber, the fluid flows from the inlet to the outlet through the conduit.

主权项

1. A valve configured to control a flow of fluid through the valve, the valve comprising:
a conduit; a first valve portion disposed at a first end of the conduit, the first valve portion having an inlet configured to interface with a respiration circuit, a first humidifier interface configured to be removably connected to a humidifier chamber, and a first conduit opening in fluid communication with an interior of the conduit, the first valve portion being configured to define a switchable flow path between the inlet and either the first humidifier interface or the first conduit opening; and a second valve portion disposed at a second end of the conduit, the second valve portion having an outlet configured to interface with a respiration circuit, a second humidifier interface configured to be removably connected to the humidifier chamber, and a second conduit opening in fluid communication with the interior of the conduit, the second valve portion being configured to define a switchable flow path between the outlet and either the second humidifier interface or the second conduit opening, wherein the first valve portion and the second valve portion are configured such that:
responsive to the first humidifier interface and the second humidifier interface to the humidifier chamber, the first valve portion and the second valve portion operatively form a flow path from the inlet to the outlet through the humidifier chamber, instead of through the conduit, andresponsive to disconnecting the first humidifier interface and the second humidifier interface from the humidifier chamber, the first valve portion and the second valve portion operatively form a flow path from the inlet to the outlet through the conduit, instead of through the humidifier chamber.
