Abstract:
1. A modular nitric oxide (NO) delivery device for selectively controlling a flow of NO therapy gas to a patient, the modular NO delivery device comprising: a housing having NO supply port, NO delivery port, and a conduit pneumatically connected to the NO supply port and the NO delivery port, wherein the modular NO delivery device is removably connected to a gas delivery system and is separately coupled to an inspiratory limb of a breathing circuit; a selector valve positioned in the conduit and selectively movable between a first position wherein the NO supply port is pneumatically connected to the NO delivery port and a second position wherein the NO supply port is pneumatically connected to a temporary supply of NO; a controller arranged to control the movement of the selector valve between the first and second positions wherein when the modular NO delivery device is coupled with the NO delivery port, the controller switches the selector valve to the first position, and when the modular NO delivery device is not coupled with the NO delivery port, the controller switches the selector to the second position; and the housing further having a power supply port, a temporary power source and a switch being selectively movable between a first position wherein power is provided to the NO delivery device via the power supply port and a second position wherein power is provided to the device from the temporary power source.
