Description

introduction

The invention relates to an oral and nose protective mask, comprising a cover made of flexibly held material, which is dimensioned such that it extends over the bridge of the nose and over the mouth, means for fixing the protective mask on the head are provided on both sides of the cover .

State of the art

Various mouth and nose protective masks are known from the prior art. Such a known mouth and nose protection is worn due to the risk of viral infection in order to avoid the infection of pathogens through secretion droplets on other people in this way. The mouth and nose protection is what is known as an everyday mask, which is intended to protect the wearer, for example from inhaling dust or other air pollution, and the environment of the wearer, for example droplets expelled when sneezing or coughing. The mouth and nose protection consists of a suitable material, such as a nonwoven fabric or a textile, which at least allows relatively large particles, for example the mentioned droplets or the like, to be discharged from the mouth and / or nose of the user into the environment prevented and at least reduced.

The materials used can also be, for example, any fabric, paper or plastic material, fiber material, fleece or the like, which is flat, for example in webs, and is cut into shape on the circumference. To put on the mouth and nose protection, it is placed over the area of the face to be covered and pressed against the part of the face in such a way that the mouth and nose protection is in contact with the edge. In order to keep the mouth and nose protection in place when in use, flexible loops are provided on the sides, for example, behind the auricles so that the mouth and nose protection lies tightly on the lower half of the face when under tension.

For example, from the DE 21 2017 000 103 U1 a mouthguard is known with a molded part extending from a chin area over the mouth and at least over the nostrils of a user, which is equipped with a circumferential adhesive tape for attachment to the skin of the user with a nosepiece and a drawstring.

The following describes the DE 10 2012 204 349 a medical face mask with a mask and a fastening means for fastening the mask to the head of a user so that the mouth of the user is covered. The mask consists of a thin, preferably flexible material that can be adapted to a facial contour of a user so that an at least largely closed volume is formed between the mask and the facial skin of the user.

With these oral and nose protective masks known from the prior art, however, there is the disadvantage that in particular the moist breathing air given off by the user can escape over the upper edge area of the oral and nose protective mask, so that a fog effect is reflected on the glasses of a spectacle wearer . Due to this fact, the eyesight of the user of the face mask is significantly impaired. Thus, the combination of face mask and glasses creates a problem that is also of great importance for doctors in the medical field. To overcome this problem, for example, from the DE 88 04 403 a respirator, consisting of a fleece carrier, a filter and a cover fleece known, in which at least partial areas or a partial area of the cover fleece consists of moisture-absorbing fleece material contained in the air, preferably in the exhaled breath, so as to reduce the moisture in the exhaled air Prevention of fogging of glasses wearers to tie the respirator.

Another way of extracting the humid air, in particular, is described by the DE 29 38 720 , in which a breathing half-mask for single use is designed in such a way that it secures a seat over the nose, the cheeks and the chin of the user and an inwardly directed sealing strip made of the same material as a sealing lip as well as head straps that are attached to the edge are attached, identifies. Sealing lips form an edge, which in particular here form a reinforcement frame for the mask, so that the mask shape retains its dimensional stability when moisture penetrates.

All these protective masks known in the prior art have disadvantages which, on the one hand, do not adequately prevent fog formation, in particular for spectacle wearers, and on the other hand, the mask cannot be reused after repeated use.

task

It is therefore the object of the invention to provide an oral and nose protective mask comprising a cover made of flexibly held material to be further developed in such a way that on the one hand it is to be used as a reusable protective mask, on the other hand the mouth and nose protective mask should prevent the glasses from fogging up, especially for people who wear glasses.

solution

According to the invention, this problem is solved with the features of claim 1; advantageous embodiments result from the subclaims.

The advantages achieved with the invention are that due to a detachable insert located on the inside at the upper edge of the protective mask, it is ensured that especially moist breathing air can be purposefully discharged so that it can no longer come into contact with the glasses of a spectacle wearer. Because the insert can be releasably inserted and fixed in the textile mouth and nose protection, there is now the possibility that the mask can be washed and cleaned so that it can be made available for reuse.

In a further development of the invention, the insert here comprises a nasal bridge with legs that extend over the cheek areas. Because of this design, the insert, like the mask itself, covers the entire lower half of the face. In a further development, the legs are also U-shaped and open towards the mouth area. Due to this design, the moist, exiting breathing air is first caught below the insert and here in the U-shaped legs of the insert, and then discharged laterally by exhaling. For this purpose, the U-shaped legs are open at their free ends so that breathing air can escape undisturbed.

According to an advantageous embodiment of the invention, the U-shaped legs are designed to be anatomically shaped with their areas resting on the cheeks. Because of this design, a tight, but also a non-disruptive fit of the mask with use in the face area is provided.

According to a particularly advantageous embodiment of the invention, the insert is attached to the inside of the protective mask by means of a detachable adhesive fastener. The adhesive fastener is formed from a Velcro fastener. For this purpose, a hook and loop tape with the barb is attached to the insert, with a hook and loop tape with loops sewn into the upper edge of the protective mask. Thus, the insert can be easily and simply pulled out of the textile face-to-face mask or detached, with the insert being able to be reinserted easily and precisely after cleaning the protective mask. The insert as such is made from a soft plastic so that it has flexibility in connection with the mask.

With the means of establishing 4th it can be flexible loops - as shown - so that the face mask 1 is fixed in the attached state by means of the loops on the ears. As in particular from the synopsis of 1-4 can be seen on the inside at the top 5 the protective mask 1 a removable insert 6th intended for the removal of the moist breathing air.

The use 6th as such is in particular more detailed in the 2 and 3 to be seen more closely, this being a nasal bridge 7th with thighs 8th and 9 includes that extend across the cheek areas. Here are the legs 8th and 9 U-shaped, as shown in the 1 can be seen in the side view. The U-shaped legs 8th and 9 are open towards the mouth so that they catch the exhaled moist air. The U-shaped legs are in further development here 8th and 9 at their free end 10 open so that over the opening 10 At the end of the day, the resulting breath can escape easily and unhindered. As a result of this configuration of the U-shaped leg areas, which are open towards the bottom, the moist breathing air will escape via the upper edge area 5 the mouth and nose protective mask 1 up prevented in such a way that moist air cannot draw into the glasses area.

As in particular from the 2 and 3 the U-shaped legs can be seen 8th and 9 with their adjacent areas not shown 11 Anatomically shaped so that the area facing the face is in close contact with the skin of the face.

According to a particularly advantageous embodiment, the insert 6th by means of a detachable adhesive fastener 12 on the inside of the face mask 1 attached as this in the 2 is shown. Here is the adhesive fastener 12 designed as a Velcro, as indicated in the perspective view of 2 . To produce the Velcro is used 6th a Velcro strip 13 provided with barbs, being at the top 5 the mouth and nose protective mask 1 a Velcro strip 14th is sewn with loops, as shown in the 4th can be recognized by the hatched area. This training now enables the use of the face mask 1 the use 6th easy and simple to integrate by joining the adhesive surfaces here. If it is desired or required that the cover 3 the mouth and nose protective mask 1 should be washed, so the use 6th simply from the inside of the cover 3 separate again.

In further training, especially in deployment 6th it consists of a soft plastic that fits tightly and comfortably to the skin of the face so that the insert can be used 6th the mouth and nose protective mask 1 can also adapt to the facial expressions of the face.
