  • the ventilator is an emergency ventilator as used by emergency physicians and first responders in emergency situations.
  • a defibrillator under the type designation “corpuls 3 ” from GS Elektro Kunststoffische Act G. Stemple GmbH in Kaufering (DE) is also known as a portable medical device, but not a respiration device.
  • the known defibrillator can be pivoted over an angular range of approximately 30° in a frame accommodating the defibrillator.
  • the applicant's “Hamilton-G5” ventilator is known, which has a monitor with a control panel that can be pivoted relative to the rest of the device housing.
  • Emergency ventilators also referred to as “intensive care ventilators”, among other things, are used to quickly supply a patient with breathing gas outside of a clinical environment, ie, for example, at the scene of an accident and/or while a patient is being transported.
  • emergency ventilators can also be used in a clinical setting, but more powerful ventilators than emergency ventilators are often available in hospitals.
  • emergency ventilators like the present ventilator, preferably have their own energy store, which enables the emergency ventilator to be operated independently of a mains supply, at least for a certain period of time.
  • emergency ventilators like the present ventilator, are designed as portable ventilators in terms of their size and weight, so that they can be used by an emergency medic, such as an emergency doctor called at the scene of an accident, using only their own muscle power, even over distances of several Dozens of meters can be moved without excessive physical strain.
  • emergency ventilation devices have a blower as a preferred pressure-changing device
  • these emergency ventilation devices can administer at least ambient air as breathing gas without additional special gas supplies, such as a detachably coupled oxygen supply.

  • emergency ventilation devices like those of the present invention, usually have a connection formation for connecting a special gas supply. In order to protect the functional arrangement from external influences, such as mechanical shocks, dirt and the like, it is arranged in the device housing.

  • the connection of the input/output device and the control device for signal transmission means that signals and thus data and information can be transmitted between these devices.
  • the ventilator Due to the applicability of the present ventilator as a portable ventilator at accident sites and in medical transport vehicles, including ground-based vehicles, aircraft and watercraft, it is important that the ventilator be adaptable to different operating environments and operating situations and that it can be optimally operated in these different environments and situations. In very few cases is there an ergonomically suitable contact surface as a work surface for the ventilation device.
  • the present invention solves this problem with a ventilation device of the type mentioned at the outset, which has a frame, the device housing with the input/output device arranged thereon being rotatably mounted on the frame about a virtual axis of rotation.

  • the effect on the person operating the ventilation device of the different operating situations caused primarily by the different possible storage heights can be mitigated by the rotatable receptacle of the device housing in the frame.
  • the device housing with the input/output device in the frame can thus be rotated about the axis of rotation in such a way that the input/output device points towards the person operating it.
  • the rotatability of the overall arrangement of device housing and input/output device is preferred to the known relative tiltability of a control console or control panel as an input/output device relative to the rest of the device housing, since the ventilation device remains compact regardless of the orientation of the overall arrangement. If instead only the input/output device were folded out away from the device housing towards the operator, the risk would be increased that other people moving in the operating environment of the ventilation device would collide with the folded out part of the device and thereby impair the ventilation situation of an artificially ventilated patient.

  • the at least one contact formation preferably defines a plurality of virtual contact areas, their position and/or orientation relative to one another by rotating the device housing about the axis of rotation is changeable to provide an operator with multiple options for turning off the ventilator.
  • the axis of rotation preferably runs at a distance from at least one output surface, such as a monitor, of the input/output device, in particular from the input/output device, so that the output surface and/or the input/output device run through a relatively long curved path when the entire arrangement rotates about the axis of rotation can.
  • the input/output device can be displaced to any appreciable extent and at the same time angularly oriented.
  • the axis of rotation can run outside of the device housing, which leads to a relatively large space for movement of the device housing with the input/output device.
  • a compact movement space with nevertheless sufficient possibility for orienting the entire arrangement according to its storage situation can be obtained in that the axis of rotation passes through the device housing.
  • the ventilation device has a plurality of physical functional interfaces.

  • a functional interface for establishing a fluid-mechanical connection can also be used to connect a breathing tube, via which respiratory gas is conveyed from the pressure-changing device in the device housing to a patient.
  • a functional interface for producing a mechanical connection can be used to connect a suction-side filter, which has specific filter properties that go beyond the filter properties of a breathing gas filter that is preferably arranged in the device housing so that it can be replaced.
  • a gas supply can be a gas supply received in a container or a gas supply provided in a building or transport vehicle by means of installation lines and coupling formations for connection.
  • At least one of the plurality of functional interfaces is axial with respect to the prism axis arranged end face of the device housing.
