Abstract

The invention relates to a delivery device (1) for supplying breathing air into a breathing air region (B) of a person (10) and comprises an air supply hose (2), a mouthpiece (3) with an outflow opening (3.1) for supplying the breathing air into the breathing air region ( B) and a connection opening (3.2) for connection to the air supply hose (2), wherein the mouthpiece (3) is transparent, and a holding device (4) for fixing the air supply hose (2) to the person (10).

Description

  • The invention relates to a supply device for supplying breathing air into a breathing air area of a person.
  • It is known that wearing respiratory masks can protect against air pollution, infections, pollen or the like. These breathing masks are worn resting on the face while covering the nose and mouth and are therefore often perceived as disturbing by the user. Another disadvantage is that moisture accumulates under the mask during wear, which is also perceived as unpleasant by the user.
  • The invention has for its object to provide a delivery device for supplying breathing air in a breathing air of a person, which is not perceived by the user as disturbing.
  • This object is achieved by a supply device for supplying breathing air into a breathing air area of a person with the features of patent claim 1.
  • Such a delivery device for supplying breathing air into a breathing air area of a person comprises:
    • an air supply hose,
    • a mouthpiece having an outflow opening for supplying the breathing air into the breathing air area and a connection opening for connection to the air supply hose, wherein the mouthpiece is made transparent, and
    • - A holding device for attaching the air supply hose to the person.
  • In this feeding device according to the invention, the mouthpiece is not on the face, but is held over the air supply hose and the bracket, with which the air supply hose is attached to the user, in the breathing air area of the user, as in the area of the mouth and nose, so that Breathing air flow can flow targeted through the mouthpiece in this breathing air of the user. The fact that the mouthpiece is kept at a distance to the mouth and / or nose, the exhaled humidity is discharged directly into the environment.
  • Another advantage of the feeding device according to the invention is that the mouthpiece is transparent, whereby the mouth movements of the user can be recognized by another person. As a material for such a transparent mouthpiece, for example, polycarbonate can be used.
  • It is particularly advantageous if, as a further development, the mouthpiece is detachably formed with the air supply hose. Thus, such a mouthpiece is interchangeable and can be adapted to the user. In addition, a simple cleaning of the same is possible by the interchangeability of the mouthpiece.
  • According to a preferred embodiment of the invention, the outflow opening of the mouthpiece is formed with an oval opening cross-section, wherein the contour of the outflow opening is adapted to the contour of the lips of the person. This leads to a small size of the mouthpiece.
  • A further advantageous embodiment of the invention provides that the outflow opening of the mouthpiece is formed with a circular, square or rectangular opening cross-section, wherein the opening cross-section of the outflow corresponds to the size of the breathing air area surrounding the mouth and the nose of the person. The size and shape of the mouthpiece can be varied and individualized.
  • Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings. Showing:
    • 1 a perspective view of a person's head with a first embodiment of a supply device for supplying breathing air according to the invention,
    • 2 a representation of a person's head with a second embodiment of a supply device for supplying breathing air according to the invention, and
    • 3 a representation of a person's head with a third embodiment of a supply device for supplying breathing air according to the invention.
  • The in the 1 . 2 and 3 shown feeding device 1 for supplying breathing air into a breathing air area B of a user 10 includes an air supply hose 2 , a mouthpiece 3 and a holding device 4 ,
  • The air supply hose 2 encloses a U-shaped or semicircular head 11 the user 10 and is by means of the holding device 4 attached to the head 11. At the back of the head 11 lying end of the air supply hose 2 Breathing air is supplied while in the breathing air area B of the user 10 located end of the air supply hose 2 the mouthpiece 3 is arranged. This mouthpiece 3 has an outflow opening 3.1 on, with which the breathing air in the breathing air area, ie in the area of the mouth and nose of the user 10 is passed without the mouthpiece 3 on the face of the user 10 rests. By means of a connection opening 3.2 is the mouthpiece 3 on the end of the air supply hose 2 releasably inserted. For this purpose, the contours of the connection opening 3.2 of the mouthpiece 3 and the end portion of the air supply hose 2 adapted to each other.
  • With the solvability of the mouthpiece 3 from the air supply hose 2 can the mouthpiece 3 be carried out interchangeably, so that according to the need of the user 10 different mouthpieces 3 can be made, for example, are adapted in size and shape to the needs of the user 10.
  • So are in the 1 . 2 and 3 different shapes and sizes of mouthpieces 3 shown. For example, the mouthpiece 3 to 1 with an outflow opening 3.1 formed with a circular or oval contour, wherein the contour of the outflow opening 3.1 to the contour of the mouth or lips of the user 10 is adjusted. This leads to a small design of the mouthpiece 3 ,
  • The mouthpiece 3 to 2 has a larger design and thus generously covers the area of the user's mouth 10 but without lying on his face. The associated outflow opening 3.1 can, for example, be formed again with an oval or rectangular contour.
  • The 3 shows a mouthpiece 3 , which not only the area of the mouth, but also a part of the nose of the user comprising the nostrils 10 covering, but without lying on the face of the user 10. This mouthpiece 3 to 3 therefore has a large design. For this mouthpiece 3 are provided circular, square or rectangular opening cross sections or other suitable geometric shapes, so that the opening cross section of the discharge opening 3.1 the size of the mouth and nose of the user 10 comprehensive breathing air area B corresponds.
  • To ensure the exchangeability of the mouthpieces 3 have the connection openings 3.2 the different mouthpieces 3 of course identical contours. With this interchangeability of the mouthpieces 3 combines the advantage that they are easy to clean.
  • Because the air supply hose 2 by means of the holding device 4 with the head 11 the user 10 is connected, there is the mouthpiece 3 spaced to the mouth and nose of the user 10 , This distance between the mouthpiece 3 and the mouth or nose of the user 10 can be adjusted individually if the air supply hose 2 is changeable in its form.
  • Because of this mouthpiece 3 not on the user's face 10 The exhaled air humidity can be released directly into the environment.
  • The mouthpiece 3 is transparent, allowing for a communication partner of the user 10 whose lip movements through the mouthpiece 3 visible and thereby communication is facilitated. As material for this mouthpiece 3 is, for example, polycarbonate suitable.
