  • the present invention relates to a ventilated full-face individual protection device, of the type which comprises an integral cover for the head and face of a user / patient, fixed below the neck, which allows to isolate at the same time the mouth, the nose, and the eyes, which are the traditional access routes for any harmful substance or micro-organism.
  • CPAP Continuous Positive Airway Pressure
  • a first example of a ventilated full-face individual protection device is described in the patent text US2014331999A1 which mentions a helmet for the non-invasive ventilation of patients, comprising a body / container in which the head of a patient can be housed, provided with at least one portion optically transparent and of an open end to which a first rigid ring is fixed.
  • a first rigid ring is fixed to the aforesaid first rigid ring.
  • an elastically yielding collar can be removably and sealedly coupled to the patient's neck and fixed to a second rigid ring, the distinctive feature of which consists in comprising a bayonet.
  • coupling means suitable for removably coupling the first and second rigid rings.
  • Patent document EP2481433A2 describes a helmet for artificial respiration, without the aid of face masks or tracheal tubes and with a good fit.
  • the helmet comprises a body, which encloses the patient's head, and a collar, designed to form a hermetic seal around the patient's neck, made of flexible plastic material. Fittings fixed on the body of the helmet, for connecting a ventilation apparatus, and accessories for air release are included.
  • the collar is directly connected to a lower end of the helmet body, and the body and collar are made of flexible material, thus free of rigid structural elements.
  • the purpose of the present invention is to provide a ventilated full-face individual protection device, efficient and comfortable to wear, which ensures that a user's mouth, nose and eyes are hermetically sealed, thus having characteristics such as to overcome the limits that still affect currently a ventilated full-face individual protection device, with reference to the known art.
  • a further object of the present invention is to provide a ventilated full-face individual protection device that guarantees safety conditions, especially when it is removed, reducing the likelihood that it may accidentally touch the user's face.
  • a further object of the present invention is to provide a ventilated full-face individual protection device that is comfortable to wear, which keeps the user's face away from discomfort, rubbing and skin irritation.
  • a ventilated full- face individual protection device is realized, as defined in claim 1.

  • the protection device 100 comprises an electric fan 103 positioned on the first air filter 102 and configured for the inflation of the inflatable helmet 101 and for the circulation of air inside the same inflatable helmet 101.
  • the protection device 100 comprises a second respiratory filter 104 which is interchangeable and positioned on a second through hole obtained on a second portion of the inflatable helmet 101.
  • the protection device 100 comprises a hollow perimeter profile 105, having substantially cylindrical or toroidal shape, fixed in correspondence with a base portion of the inflatable helmet 101 and able to removably position the protection device 100 around the head 51 of the user 50.
  • the electric fan 103 is adapted to be powered by a USB port or by a 12 Vdc socket.
  • the first air filter 102 is made of carbon.
  • the protection device 100 is fixed around the head 51 of the user 50 by means of a fastening element positioned on a portion of the perimeter profile 105.
  • the aforementioned fastening element is chosen from the group consisting of: natural or synthetic fiber lace; elastic means; velcro; zip closure.
  • the inflatable helmet 101 is made of a soft and transparent material, for example PVC, TPU or EPDM rubber.
  • the protection device 100 allows the face to be kept completely free, unlike known systems which, when tightened to the face, are uncomfortable, especially in prolonged use, and often cause sores, unlike the protection device 100 which can be comfortably worn for long periods without causing rubbing or irritation on the skin.
  • the protection device 100 ensures the safety of the patient 50, especially when it is removed from the head 51, since the external part of the device does not accidentally touch the face, being removed by pulling it upwards.
  • the presence of the electric fan 103 ensures the inflation of the inflatable helmet 101, maintaining its substantially cylindrical shape, and guarantees the circulation of air inside the helmet, with the consequent climatic comfort and absence of condensation.
  • the electric fan positioned and tightened on the first air filter 102, is removable.
  • the realization of the inflatable helmet 101 by means of a soft material among those mentioned above, and the removability of the electric fan 103, in addition to a high comfort for the user 50, allow the protection device 100 to be comfortably foldable to, for example, be housed in a bag for easy transport.
  • the use of the first air filter 102 preferably a carbon filter, prevents the air inside the protection device 100 from being contaminated .
  • the use of the second respiratory filter 104 allows the user 50 to breathe even with the electric fan 103 disconnected.
  • the protection device 100 is adjusted to the height of the neck 52 and fixed by means of the fastening element which, as mentioned, is preferably constituted by a natural or synthetic fiber, by elastic means, by a velcro or by a zip closure.
  • This fastening element is positioned on a portion of the perimeter profile 105, which can be rigid or semi-rigid and, as mentioned, have a cylindrical or toroidal shape, in this second case allowing to implement the perimeter profile 105 by means of an inflatable donut.
  • the realization of the protection device 100 by means of one of the aforementioned materials, with transparent characteristics allows a 360° view of the area surrounding the user 50, or only of the line of sight of the user 50, in the case in which the portions placed in correspondence with and behind the head 51 are covered with a second material, having covering characteristics.
  • the protection device 100 can be reused over and over again, being washable and sanitizable, without degrading the material it is made of.
  • the ventilated full-face individual protection device allows effective mechanical ventilation of a user, hermetically sealing his eyes, nose and mouth while keeping his face free.
  • the ventilated full-face individual protection device guarantees safety conditions, especially when it is removed, reducing the likelihood that the external portion of the device may touch and accidentally the face, as it is removed by pulling it upwards.
  • ventilated full-face individual protection device is its prolonged duration over time, being washable and sanitizable, without resulting in degradation.
  • a further advantage of the ventilated full-face individual protection device according to the invention is that it is easily transportable and storable.
  • the ventilated full-face individual protection device according to the invention is easy to use.
  • the ventilated full-face individual protection device according to the invention is of low cost and easily achievable on a large scale.
