Abstract
An emergency ventilator for artificially ventilating patients in the event of a medical emergency, having: —a housing with an ambient air suction opening and a ventilating gas outlet opening and—a fan which is designed and is arranged in the housing so as to convey ambient air from the ambient air suction opening to the ventilating gas outlet opening, wherein the fan includes a fan housing with an air conveyor which can be moved relative to the fan housing, and the fan housing is arranged in the housing in a fixed manner thereto; the fan housing is secured to the housing with the interposition of a heat conducting body, the heat conducting body including or being made of a material which is selected from light metal, nonferrous metal, and/or a plastic filled with a heat-conductive filler material.
Core Innovation
The invention concerns an emergency ventilator for emergency medicine artificial respiration of patients. The ventilator includes a housing with an ambient air aspiration aperture and a respiratory gas output aperture, and a fan configured to convey ambient air from the ambient air aspiration aperture to the respiratory gas output aperture. The fan comprises a fan housing with an air conveyor movable relative to the fan housing, and the fan housing is arranged housing-tight in the housing.
The fan housing is fixed to the housing with the interposition of a heat-conducting body. The heat-conducting body comprises a material chosen out of light metal, non-ferrous metal, and/or a synthetic filled with heat-conducting filling material, so that heat is transferred via the heat-conducting body between the fan housing and the housing and can be emitted to the environment through the ventilator housing.
An outer surface of the fan housing is exposed in a section of a flow path from the ambient air aspiration aperture to the respiratory gas output aperture, so that during a ventilation operation it can be bathed by respiratory gas conveyed by the fan. In embodiments, the heat-conducting body forms a wall of a region enclosing a respiratory gas, surrounds a mixing chamber on four sides forming a recess, and arranges the outer surface of the fan housing within the recess so the exposed surface is bathed by respiratory gas.
Claims Coverage
The independent claims in the provided set are clm-00001, clm-00018, and clm-00019. Across these claims, the coverage centers on an emergency ventilator with a housing-tight fan housing fixed via a heat-conducting body made from selected light metal, non-ferrous metal, and/or heat-conducting synthetic materials, together with respiratory-gas bathing of an exposed fan-housing outer surface along the flow path.
Housing-tight fan housing fixed via interposed heat-conducting body
The fan comprises a fan housing with an air conveyor movable relative to the fan housing, where the fan housing is arranged housing-tight in the housing and is fixed to the housing with the interposition of a heat-conducting body comprising light metal, non-ferrous metal, and/or a synthetic filled with heat-conducting filling material.
Respiratory-gas bathing of exposed fan housing outer surface in the flow path
An outer surface of the fan housing is exposed in a section of a flow path from the ambient air aspiration aperture to the respiratory gas output aperture so that during a ventilation operation it can be bathed by respiratory gas conveyed by the fan.
Heat-conducting body forming wall of region enclosing respiratory gas and recess around mixing chamber
The heat-conducting body forms a wall of a region enclosing a respiratory gas and surrounds a mixing chamber on four sides to form a recess, with the outer surface of the fan housing arranged in the recess and bathed by respiratory gas.
Joint-face size relationship between heat-conducting body and fan housing
The heat-conducting body exhibits a fan joint-face opposite a section of the fan housing and a housing joint-face facing an inner surface of the housing, where the housing joint-face is at least twice as large as the fan joint-face and at least six times as large as the fan joint-face.
The claims collectively cover an emergency ventilator architecture using a housing-tight fan housing fixed via an interposed heat-conducting body and an exposed fan-housing outer surface bathed by respiratory gas along the respiratory-gas flow path, with additional claim-dependent features concerning a recess around a mixing chamber and relative joint-face sizes.
