Abstract
The invention relates to a protective cover (1) for a medical ventilator (20) adapted for use in a contaminated environment, in particular an NRBC environment, having a peripheral casing (2) defining an internal compartment (3) designed to accommodate a medical ventilator (20). The peripheral casing (2) has a plurality of connection interfaces (4, 5, 6, 7) sealably attached to said peripheral casing (2). Each connection interface (4, 5, 6, 7) has at least one internal gas passage with at least one gas inlet and at least one gas outlet. A sealing device is arranged in the internal gas passage of at least one connection interface (4, 5, 6, 7) for sealing said internal gas passage.
Core Innovation
The invention provides a protective cover for a medical ventilator adapted for use in a contaminated environment. The protective cover includes a peripheral casing defining an internal compartment designed to accommodate the medical ventilator and providing sealed interfaces for connection to external components.
The peripheral casing comprises a plurality of connection interfaces sealably attached to the peripheral casing. A first connection interface allows fluid connection of a patient circuit, and a second connection interface allows fluid connection of an air purification device. Each connection interface comprises at least one internal gas passage with at least one gas inlet and at least one gas outlet.
At least one sealing device is arranged in at least one internal gas passage of at least one connection interface for sealing the internal gas passage. The protective cover is described with hermetic opening and closing means, sealing and closure features suitable for harsh conditions, including an IP67 rating, and a ventilation assembly/system architecture using the covered medical ventilator together with patient circuit and purification and oxygen components.
Claims Coverage
The independent claim defines the protective cover architecture. It includes four inventive functional elements: a peripheral casing with an internal compartment for the medical ventilator, multiple sealable connection interfaces for patient circuit and air purification device, internal gas passages with inlets and outlets in the interfaces, and an internal sealing device arranged to seal the internal gas passages.
Protective cover with peripheral casing and internal compartment for a ventilator
A protective cover for a medical ventilator adapted for use in a contaminated environment, comprising a peripheral casing defining an internal compartment designed to accommodate the medical ventilator.
Sealable connection interfaces for patient circuit and air purification device
The peripheral casing comprises a plurality of connection interfaces sealably attached to said peripheral casing, including a first connection interface allowing fluid connection of a patient circuit and a second connection interface allowing fluid connection of an air purification device.
Internal gas passages with inlet and outlet in each connection interface
Each connection interface comprises at least one internal gas passage with at least one gas inlet and at least one gas outlet.
Internal sealing device arranged in the internal gas passages
At least one sealing device is arranged in the at least one internal gas passage of at least one connection interface for sealing said at least one internal gas passage.
The provided claim set further extends the sealed interface concept to additional interfaces, including a PEP pressure control line and an oxygen supply line, and refines the sealing device type, for example as a non-return valve. The scope is further extended to a ventilation system including the patient circuit components and an oxygen container connected through the protective cover.
Stated Advantages
Not explicitly described in patent.
Documented Applications
Use of a medical ventilator with a protective cover in a contaminated environment.
A ventilation assembly/system architecture using the protective cover with a patient circuit, an air purification device, and oxygen components, including an oxygen container.
