Emergency ventilator with removable common cover for simultaneously covering filter and battery compartment

An emergency ventilator for emergency medicine artificial respiration of patients, comprising:

• a housing with an ambient air aspiration aperture and a respiratory gas output aperture,
• a fan which is configured and arranged in the housing in order to convey ambient air from the ambient air aspiration aperture to the respiratory gas output aperture,
• an air filter which is configured for cleaning aspirated ambient air and is arranged in the housing in a flow path of the ambient air downstream of the ambient air aspiration aperture, and
• an energy store for supplying the fan with energy for its operation,
• where the air filter is accessible through a first housing aperture which is closed by means of a first housing lid but is openable and in normal operation is accommodated in the housing in a replaceable manner,
• where the energy store is accessible through a second housing aperture which is closed by means of a second housing lid but is openable and in normal operation is accommodated in the housing in a replaceable manner, and
• where the first and second housing apertures are a common housing aperture and the first and second housing lid are a common housing lid such that the air filter and the energy store are thus accessible through the common housing aperture, where the common housing aperture can thus be closed and opened selectively through the common housing lid.
