Abstract
An emergency ventilator for artificially ventilating patients in the event of a medical emergency, including: —a housing with an ambient air suction opening and a ventilating gas outlet opening, —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, —an air filter which is designed to purify suctioned ambient air and which is arranged in the housing downstream of the ambient air suction opening in the flow path of the ambient air, and —an energy storage device for supplying the fan with energy in order to operate same, wherein the air filter is received in the housing in an accessible manner through a housing opening, which is closed but can be opened by a housing cover, and so as to be replaceable in an intended manner, and the energy storage device is received in the housing in an accessible manner through the housing opening, which is closed but can be opened by the housing cover, and so as to be replaceable in an intended manner, the air filter and the energy storage device can be accessed through a common housing opening, the common housing opening being selectively closable and openable by a common housing cover.
Core Innovation
The invention relates to an emergency ventilator for emergency medicine artificial respiration of patients that conveys ambient air from an ambient air aspiration aperture to a respiratory gas output aperture. Ambient air is cleaned by an air filter arranged in a flow path downstream of the ambient air aspiration aperture, while a fan is configured and arranged in the housing to convey the ambient air to the respiratory gas output aperture. An energy store supplies energy for operation of the fan.
A core aspect is that both the air filter and the energy store are accessible through a common housing aperture and are closed and opened selectively through a common housing lid. The air filter is accessible through a first housing aperture closed by a first housing lid but openable and accommodated in the housing in a replaceable manner, while the energy store is accessible through a second housing aperture closed by a second housing lid but openable and accommodated in the housing in a replaceable manner. The first and second housing apertures are the common housing aperture and the first and second housing lid are the common housing lid, so the air filter and the energy store are thus accessible through the common housing aperture.
The disclosed configuration further provides an integrated access layout in which an ambient air aspiration aperture is spatially arranged through the lid/latching component. In addition, a filter cartridge inlet aperture and a special-gas connector formation are positioned to operate compactly in a coaxial manner for the ambient-air filter cartridge arrangement. The document also describes a locking/latching mechanism for the common housing lid, including a rotatable latching component and a bayonet catch, to enable selective closing and opening of the common housing aperture.
Claims Coverage
The independent claim is claim 1, which defines an emergency ventilator with an ambient-air fan path and an air filter, powered by an energy store, where both components are replaceably accessible through a common housing aperture closed/opened by a common housing lid. The dependent claims further specify latching/locking positioning structures, a special-gas connector formation, coaxial alignment relative to a latching axis, housing form details, and a shock-absorbing element on the common housing lid.
Emergency ventilator with ambient-air fan path and output aperture
An emergency ventilator comprising a housing with an ambient air aspiration aperture and a respiratory gas output aperture; a fan configured and arranged in the housing to convey ambient air from the ambient air aspiration aperture to the respiratory gas output aperture; an air filter configured for cleaning aspirated ambient air and arranged in the housing in a flow path downstream of the ambient air aspiration aperture; and an energy store for supplying the fan with energy for its operation.
Common housing aperture and common housing lid providing selective replaceable access
The air filter is accessible through a first housing aperture closed by means of a first housing lid but openable and accommodated in the housing in a replaceable manner, and the energy store is accessible through a second housing aperture closed by means of a second housing lid but openable and accommodated in the housing in a replaceable manner, where the first and second housing apertures are a common housing aperture and the first and second housing lid are a common housing lid so that the air filter and the energy store are accessible through the common housing aperture and the common housing aperture can thus be closed and opened selectively through the common housing lid.
Common lid locking-position sections securing filter cartridge and energy store body
An emergency ventilator in which a common housing lid with locking-position sections cooperates, in a ready-to-operate state, with corresponding housing-tight positioning sections to secure either a filter cartridge for filtering ambient air or an energy store body in respective operational positions.
Filter cartridge with ambient air inlet aperture and special gas connector formation
An emergency ventilator in which a filter cartridge includes an ambient air inlet aperture accessible via an ambient air aspiration aperture and a special gas connector formation for connecting a special gas supply.
Coaxial arrangement relative to a latching axis
An emergency ventilator configured so that the ambient air inlet aperture, the special gas connector formation, and the operational locking state are arranged coaxially relative to a latching axis.
Housing basic shape where common housing lid forms an end face
An emergency ventilator in which the housing has a prismatic and/or cylindrical basic shape where the common housing lid forms an end face of the prismatic and/or cylindrical housing.
Shock-absorbing element on outer surface of the common housing lid
An emergency ventilator having a common housing lid with at least one shock-absorbing element on its outer surface.
Across the independent claim and its dependents, the inventive coverage centers on an emergency ventilator that conveys ambient air via a fan and cleans it with an air filter using an energy store for fan operation, combined with replaceable accessibility of both the air filter and the energy store through a common housing aperture closed/opened by a common housing lid. Additional dependent features include lid-based locking/positioning for filter and energy store, a filter cartridge with a special gas connector formation, coaxial arrangement relative to a latching axis, specified housing geometry, and a shock-absorbing element on the lid.
