Abstract: An apparatus for delivering a flow of gas has a housing, a cover, and a magnetic coupling system arranged to magnetically couple the cover—to the housing. Each of the housing and cover having complementary locating features, the locating features being adapted to locate and align the cover and the apparatus relative to each other to allow for the magnetic coupling. The apparatus also has a handle movably connected to the housing and is movable from a first position to a second position. The housing and the handle comprise complementary interlock features arranged to engage with each other when upward force is applied to the handle in the second position, and the interlock features are disengaged from each other when the handle is in the second position but upward force is not applied to the handle.

Abstract: An apparatus for delivering a flow of gas, has a housing 3202? with a recess, and an outlet port 3210? for a flow of gas. The recess is defined by at least one wall 3256, 3262 that is substantially continuous, gas impermeable, and unbroken, other than a gasflow passage from the recess to the outlet port of the housing.

Abstract: An apparatus for delivering a flow of gas has a housing and a humidifier. The housing has a recess for a motor and/or sensor module, an outlet port for a flow of gas, and a removable elbow for a flow of gas. The humidifier has a heater, a chamber bay for receipt of a liquid chamber, and a lever and/or detent(s) for assisting with insertion and/or retention and/or removal of the liquid chamber in and/or from the chamber bay.

Abstract: A breathing assistance apparatus has a housing with an engagement feature and an electrical component in the housing and a removable component. The electrical component has a receptacle. The removable component has an electrical connector that is a close or tight fit in the receptacle of the electrical component to assist with holding the removable component in connection with the electrical component. The removable component has a tab with a terminal end portion that can be flexed relative to the rest of the removable component. An engagement feature is provided on the terminal end portion of the tab and engages with the engagement feature of the housing to inhibit disconnection of the removable component from the housing in the absence of actuating the terminal end portion of the removable component to flex the tab.

Abstract: An apparatus for delivering a flow of gas has a housing 100, a cover 5105a, and a magnetic coupling system arranged to magnetically couple the cover 5105a to the housing 100. Each of the housing 100 and cover 5105a having complementary locating features 6005, 6007, the locating features being adapted to locate and align the cover 5105a and the apparatus relative to each other to allow for said magnetic coupling. The apparatus also has a handle 500. The handle 500 is movably connected to the housing 100 and is movable from a first position to a second position. The housing and the handle comprise complementary interlock features 103, 503.
