Definitions

• the present invention relates to a breathing mask for breathing humans.
• a ventilator that can be worn at night can help with this so-called apnea.
• the disease is caused by a slackening of the pharynx muscle tissue and, in addition to an undersupply of essential oxygen, often also leads to problems with the partner in question as a result of the resulting erectile dysfunction.
• the individual suspension phases of breathing last between about ten seconds and one minute.
• One solution to this problem can be to use a respirator with a breathing mask.
• This is an apparatus that works according to the so-called CP AP method (Continous Positive Air Pressure) and supplies the patient with pressurized air by means of a slight overpressure via a hose feed and a face mask to be put on at night. Pressures of up to 16 millibars are used.
• a breathing mask which is characterized by one or more of the following devices according to the invention, namely a fastening device of a fastening tape for pressure-reducing attachment of the breathing mask to the human face with fastening tape, a soundproofed air outlet, an air supply connection piece, and a mask seal for sealing but skin-friendly contact of the mask with the human face.
• the fastening device of a fastening band for the pressure-reducing attachment of the breathing mask on the human face with fastening band is characterized in accordance with the invention in that it has a balance beam which is connected to the breathing mask approximately centrally via joints and on the other hand to the fastening band at the edge via attachment points .
• rigid mounts are provided on the side of the actual mask, to which two lateral headbands are connected for fastening. This inevitably leads to the mask slipping if the head moves involuntarily while sleeping. This can only be countered by increasing the contact pressure, which in turn leads to skin problems.
• the side headbands are now connected to the breathing mask in such a way that the force from the headbands is central to the area of the nose, i.e. about in the area of the bridge of the nose.
• the pressure forces can be low, which is accompanied by a reduction in skin problems.
• the balance beam can also be articulated on the respiratory mask via exactly one joint.
• the joints it is preferably universal or ball-and-socket joints which can be deflected in all directions, because the above-mentioned balance beam should be supported in such a way that not only horizontal pivoting, but also conditionally vertical pivoting of the balance beam with respect to the support point is possible.
• the sound-damped air outlet according to the invention is characterized in that the air outlet has a silencer made of open-cell foam. This can be surrounded by a jacket, preferably made of plastic.
• the muffler can be inserted or attached in the area of the breathing mask, or it can also surround the supply air hose at a perforated point in the hose.
• a separate housing for the muffler is preferably provided, in particular a pipe which is open on one side and is connected to the supply air area.
• Such a silencer for example made of a plastic jacket, into which an inexpensive, fine-pored foam plug is inserted, can be replaced or cleaned if necessary. The air exhales further away from the face and is therefore less disruptive. It largely eliminates disturbing noises.
• the air supply connector between the breathing mask and the air supply system according to the present invention is characterized in that it is slidably arranged on a mounting bracket in the region of the head.
• it is designed to be detachable from the supply air hose going to the air supply system.
• the device according to the present invention thus makes it possible, for example, to keep the breathing mask open during a shorter sleep interruption, only the supply air hose having to be loosened. This makes it much easier to use.
• the supply air hose is guided via a whip holder on the bed to an adjustable, in particular displaceable, air supply connection piece attached to a mounting bracket, preferably on a head cover, to the mask.
• the air supply connector consists of a rotary adapter, a quick release, an automatic shut-off valve and fixes the mask position. If you want to get up at night, the supply air hose is disconnected at the push of a button and at the same time a flap closes the air flow. Back in bed, the supply air hose hanging on the whip holder becomes reconnected by simply plugging it in, the flap opens at the same time
• the mask seal for the tight but skin-friendly contact of the mask with the human face is characterized in that the seal is designed as a silicone tube which is at least partially filled with a jelly-like compliant material.
• the silicone tube is preferably filled to a maximum of 75%, ideally half with the jelly-like material.
• the silicone tube jacket is made thicker towards the mask than towards the skin area to be sealed.
• Respiratory masks according to the present invention therefore offer a novel, flexible and tension-compensating fastening technique. Even with a minimal adjustment pressure, the mask gets a firm hold. Skin injuries or pressure points on the nose, forehead and cheeks are eliminated.
• the breathing mask does not twist or shift due to air hose strains, nor does it lift off on one side and therefore does not cause air leakage noises, which prevents eye and ear irritation due to secondary air leakage.
• the breathing mask according to the invention has an all-round, uniform adjustment pressure, which remains constant even when the head is moved sideways.
• the mask body can be easily removed from the attachment in two easy steps. Quick cleaning is also not a problem, since the mask body including the sealing profile is smooth and seamless and has no room for "bacterial hatching".
• the mask beads which are generally used for sealing, and the sealing skins that interfere with the circulation of the skin, are replaced by a narrow, smooth, all-round silicone hollow profile, which is only partially filled with gel to exclude air.
• This flexible hollow profile adapts easily to the area around the nose. Even warts etc. in the sealing area are covered effortlessly.
• the breathing mask according to the invention By using the breathing mask according to the invention, a large number of the previously known problems when using CPAP systems are reduced or even eliminated.
• the breathing masks according to the invention ensure a common, partner-friendly, trouble-free sleep.

• the slightly pressurized air flows in the direction of arrow 36 towards the actual breathing mask 34, where it supports inhalation.
• the air then flows out through the muffler 2 in the direction of the arrow 37.
• the actual breathing mask 34 lies tightly against the face via a silicone tube 20, so that no secondary air can flow out.
• FIG. 2A shows a schematic illustration of a fastening device of the breathing mask according to the present invention in the form of a balance beam in cross section.
• the breathing mask 34 is movably connected to the so-called balance beam 30 via a joint 1.
• the balance beam itself 30 is in turn connected to the elastic, flexible headband 32, which encloses the head 35, via attachment points 31.
• FIG. 3 shows a schematic representation of an air supply connector 40 according to the present invention in longitudinal section and Figures 4 and 4A of this piece 40 in cross section. Both are discussed together below.
• a headband connecting plate 38 is provided for the support on the forehead and in particular above it, in the area of which a kind of angle or locking bracket 3 is arranged, on which the horizontal leg with the headband 4 in the direction of the arrows 5 in a different position, preferably by means of a bolt 6 can be fixed.
• the supply air hose 7 or 33 is coupled via a rotary adapter 8 with a removable intermediate piece 9, which, for. B. in a rail guide 10 of the angle bracket 3 in the direction of arrow 11 from the angle bracket 3 can be lifted or otherwise decoupled.
• an ejector spring 12 is arranged under the removable intermediate piece 9, which automatically pushes the intermediate piece 9 out of the angle bracket 3 when the snap locks 13 are actuated for this purpose.
• a butterfly valve 14 is provided, which is biased in the direction of rotation about the axial axis 15 by means of a spring 16.
• the pretensioning is carried out so that when the intermediate piece is inserted - i.e. As can be seen in Fig. 3, the butterfly valve 14 is aligned in the opening direction. This takes place automatically when the intermediate piece is inserted into the angle bracket 3 in that a control cam 18 arranged on the axle journal 17 in a manner fixed against relative rotation passes along the control curve 19 of the angle bracket 3.
• the butterfly valve 14 is thus automatically fixed in its position, it is open.
• the spring 16 When lifting the intermediate piece 9, the spring 16 automatically moves the butterfly valve 14 into the closed position so that no air can escape from the supply air hose 7 or 33. It is therefore not necessary to shut down the air supply system.
• a silicone tube 20 is used as the direct closure of the mask to the nose area, which is relatively thick-walled in the area designated by 21 and relatively thin-walled in the area designated by 22, which rests on the face.
• This silicone tube 20 is filled with a jelly-like material 39, preferably again silicone of a corresponding consistency, and then partially placed under vacuum, so that the film shown in FIG. 5B results.
• This shape arises due to the different wall thickness of the silicone tube 20 seen over the circumference of the circle.
• the mask seal has a holding profile with which it a tightly engages a groove or the like of the mask 34.
