Definitions

  • the present invention relates to a personal protection hood with breathing means.
  • hoods for artificial respiration without the aid of masks or tracheal tubes are already commercially available and are generally constituted by a container body made of optically transparent material, inside which the head of the patient can be accommodated hermetically.
  • the container body is provided with an air inlet, which is connected to a ventilation apparatus, and there are also an outlet and a whole series of connectors and elements that extend considerably the versatility and functionality of the hood.
  • hoods which are for example of the type disclosed in EP 1170026, assumed included herein by reference, have a type of manufacture and a cost that do not allow to use the hood for providing personal protection to an operator who must for example assist diseased persons or other kinds of person while avoiding potential contagion.
  • hoods which typically are of the single-patient type, i.e., are used for a long period of time by the same patient, is not suitable, again for cost-related reasons, for short therapies, since its application would not be justified for cost-related reasons.
  • the aim of the invention is to solve the problem described above, by providing a personal protection hood with means for breathing that has a minimal structure that allows to isolate the user, for example, in the case of a protective hood, by providing a hood that is practically of the disposable type, since it is reduced to its minimal components, without however thereby compromising its functionality characteristics for the purpose for which it is meant.
  • an object of the invention is to provide a protective hood that can be obtained starting from very simple and commonly commercially available elements, so as to contribute to a drastic cost reduction.
  • Another object of the present invention is to provide a hood for artificial respiration whenever it is necessary to perform short-lasting therapies with assistance, by providing a hood that is of the disposable type in view of its cost and practicality in use.
  • Another object of the present invention is to provide a protective hood that thanks to its particular constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
  • a personal protection hood with means for breathing comprising a body that is provided with an annular element whereto a container is connected which delimits a region for accommodating the head of the user and a collar for resting on the neck and shoulders of the user, at least one air inlet being further provided on said annular element, characterized in that said container is constituted by a bag which has at least one accordion-like portion and at least one optically transparent region.
  • the protection hood generally designated by the reference numeral 1
  • a body generally designated by the reference numeral 2, which is provided with an annular element 3 whereto a container 4 that delimits a region for accommodating the head of the user is connected, and a collar 5, which in practice rests on the neck and shoulders of the user.
  • a first feature of the invention consists in that the container 4 is formed by a bag made of transparent plastics, such as for example polyvinyl chloride, polypropylene, polythene, polyamide, cellulose in its ether and ester derivatives, and others, in order to provide optimum transparency together with good mechanical strength; tests have demonstrated that a thickness comprised between 30 and 100 microns is recommendable.
  • transparent plastics such as for example polyvinyl chloride, polypropylene, polythene, polyamide, cellulose in its ether and ester derivatives, and others
  • the container 4 is connected to the annular element 3, which is made of rigid plastics and can be obtained monolithically by assembling a plurality of components.
  • the bag is hermetically connected to the annular element 3 by way of connection means, provided by thermal bonding or by using a coupling that provides for an elastic layer 10 that is inserted in a seat 11 formed in the element 3, on which the container 4 is superimposed, said container being fixed by means of an outer ring 12 that is constituted for example by a plastic strap or other similar element.
  • the strap provides a mechanical compression that allows, by way of particularly simple means, to achieve the intended coupling.
  • the bag has at least one accordion-like portion, and in a preferred embodiment such accordion-like portion is arranged on the bottom and is obtained by means of a flap 15 that is folded toward the inside of the bag and is heat-sealed along the longitudinal edges of the bag.
  • the presence of the accordion-like portion is particularly important, since it allows, when air is introduced, to obtain a configuration that is approximately cylindrical despite providing the container by means of a low-cost bag.
  • At least one inlet 20 is formed in the annular element 3 and is connected to a duct 21 for introducing air.
  • the collar 5 is preferably but not necessarily connected by thermal bonding to the annular element, and in practice is designed to rest around the neck and shoulders of the user, who advantageously is dressed in a protective suit.
  • the suit which is normally fastened at the neck level, allows air seepage so that the air that is introduced in the hood is vented with a resistance that maintains a certain positive pressure inside the hood.
  • the protection hood is advantageously worn by placing the inlet in the rear part, so that the hose for feeding air does not cause hindrance to the operator.
  • straps 40 are provided that are connected to the hood, under the armpits of the user, so as to prevent the pressure of the air introduced in the hood from causing an accidental removal of the hood.
  • the arrangement described above allows to obtain a hood that has a very low cost, since the container portion is provided by means of a simple normally commercially available bag, which thanks to its type and to the presence of the accordion-like portion, can be sufficiently transparent for the operator and can also undergo deformation so as to provide, around the face of the user, a region that is conveniently large and spread out, so as to avoid inconveniencing the operator with undue contact between the bag and the face of the operator.
  • the materials used may be any according to requirements.
