Description

Adjustable forehead support device for breathing mask

technical field

The utility model relates to a forehead pad part of a breathing mask that can be supported on the user's forehead, which can be stretched and retracted automatically, so that the forehead pad can be comfortably attached to different users, so that the mask can be worn correctness.

Background technique

"Snoring" is caused by upper airway obstruction, such as obesity, aging tissue degeneration, upper airway narrowing, etc. When such patients sleep, the airway collapses due to the relaxation of throat muscles, making it difficult for air to enter the lungs smoothly. The blood oxygen concentration is too low. At this time, the brain will feel the lack of oxygen and order the body to breathe hard, thus causing a short-term awakening and unable to enter the deep sleep smoothly. Sometimes it can happen dozens or even hundreds of times in a night. The so-called "sleep apnea" will cause patients to be in a state of waking up all night, unable to enjoy high-quality sleep quality, and indirectly cause headaches when getting up during the day, easy drowsiness or drowsiness, concentration Inattention, memory loss, anxiety, personality changes, decreased libido, etc., and at night, there are snoring, frequent urination, etc., and it is easy to cause cardiovascular related diseases.

Usually, the above-mentioned "sleep apnea" treatment methods, if the condition is mild, can be improved by exercising, losing weight, sleeping on the side, avoiding alcohol or taking sleeping pills before going to bed, wearing an anti-snoring device (braces), etc., but if the condition is serious In this case, surgical treatment or non-invasive positive pressure respirator must be used as the main method. The positive pressure respirator can be used with a face mask, and the therapeutic effect can be as high as 90%. The pressure generated is to support the soft airway to maintain the smoothness of the airway, but up to 30% to 40% of the patients will suffer from air leakage, pressure from the mask, resistance to exhalation, weight of the pipeline, dry airflow, and inconvenience in carrying and other factors. , and it must be used continuously for at least 4 hours every night to achieve the therapeutic effect, and then give up the treatment halfway.

Therefore, in addition to the weight, portability, inhalation resistance and other issues of the device, continuous improvement and update, trying to make the patient's willingness to use it is the most important key to treatment, how to make the user who turns over during sleep wear a breathing mask There will be no rotational displacement. In addition to tightening the straps on both sides of the mask to achieve a good airtight fit between the mask and the face, and to maintain the positive pressure inside the mask, the mask must be tightly closed. It fits around the patient's mouth and nose, but if the pressure of the mask fits on the nose and mouth is too high, it will cause discomfort.

Therefore, there is a structural design that can disperse the pressure and be jointly borne by the forehead and around the mouth and nose, such as US6467483, US5243971 ... etc., the upper end of the mask is extended with a bracket, and the end of the bracket is provided with a The forehead pad part fits the forehead, and at the same time, there are headbands on both sides of the forehead pad part, so that the headband can be tightly tied to the user's head, so that the two sides and the top of the mask are supported by three points It is fixed, and the bracket can be used to ensure that the mask and the wearer's face are always kept in a 90-degree vertical direction without rotation and displacement, thereby maintaining a good fit between the mask and the face without air leakage.

However, due to the non-adjustable fixed type between the mask, the forehead pad parts and the bracket, it is impossible to adjust the changes according to the forehead and face shapes of different users during actual use, and thus the forehead pad parts cannot be matched with each other. Fitting the user's forehead will not only cause air leakage and insufficient air pressure, but also cause discomfort when wearing it.

Utility model content

The reason is that in order to improve the above-mentioned problem that the forehead bracket of the existing mask has no adjustment ability and cannot be used by various users. The retractable and retractable forehead pad allows different users to fit the forehead pad properly on the forehead without adjustment, and maintains the correct position for wearing the mask.

The technical scheme adopted by the utility model to solve its technical problems is: set the upper end of the face mask to extend the bracket part, and the upper end of the bracket part is equipped with a forehead pad part with a forehead pad, wherein the upper end of the bracket part is provided with a hole end with a The inner edge part of the smaller inner diameter is provided with a hole, and the forehead pad part includes a tube part extending from the front side of the forehead pad with a buckle part protruding from the outer edge of the end and a holding hole in the middle, so that the tube part Extending into the accommodating hole so that the buckle part can abut against the inner edge, and an elastic element that can elastically push the forehead pad component outward is installed in the accommodating hole.

The beneficial effect of the utility model is that the mask is fixed through the headbands on both sides of the bracket part and the straps on both sides of the mask to form a three-point fixed support state, and the forehead pad that can move forward and backward elastically and automatically The components make the mask suitable for different users with flat or convex foreheads, thereby ensuring the correctness of wearing the mask, reducing the pressure of the mask on the bridge of the nose, and improving the comfort of wearing.

Detailed ways

Please refer to Fig. 1～shown in Fig. 3, the utility model is that a bracket part 11 is extended upwards at the bridge of the nose at the upper end of the breathing mask 1, and a housing hole 10 is established at the end of the bracket part 11, and the housing Both sides of the hole 10 are provided with strap-through ears 13 for wearing the headband, and a forehead pad part 2 that can be supported on the user's forehead is installed at the hole 10, and then the bracket part 11 The accommodating hole 10 and the forehead pad component 2 form a forehead supporting device.

Wherein the above-mentioned forehead pad component 2 is to comprise a front side of a forehead pad 23 and establish a tube portion 21 protruding and having a cavity 20 in the middle, and make the tube portion 21 split into several petals with elastic opening and closing, and in the tube The outer edge of the end of the tube part 21 is protrudingly provided with a buckle part 22, and at the hole end of the accommodating hole part 10 provided on the upper end of the above-mentioned bracket part 11, a buckle part 22 at the end of the tube part 21 can be forcibly passed through. And the inner edge portion 12 (as shown in FIG. 3 ) with a smaller inner diameter, and then an elastic element 3 that can elastically push the forehead pad component 2 outward is set between the tube portion 21 and the accommodating hole portion 10 .

Therefore, the upper end of the mask 1 can be fixed by wearing the headband through the strap-through ears 13 on both sides of the above-mentioned bracket part 11, and the laces on both sides of the mask 1 can be added to form a three-point fixed support for the mask 1. , to keep it in the correct position without shifting, as shown in Figure 4, through the forehead pad part 2 that can be elastically stretched back and forth on the upper end of the bracket part 11, no matter who has a flat forehead Or more convex, the forehead pad part 2 is pushed or compressed by the inner elastic element 3, and automatically stretches out and rests on the forehead of the person with a flat forehead, or retracts automatically and rests on the forehead of the person with a convex forehead. On the forehead, it can not only ensure the correctness of wearing the mask 1 to prevent air leakage, but also reduce the pressure on the bridge of the nose of the mask 1. At the same time, different users do not need to adjust the forehead pad part 2, that is, Correct and comfortable wearing of the mask 1 can be obtained.
