Description

Breathing mask free-adjustable forehead backing device

The present invention relates to a frontal part of a respiratory mask that can be placed against the forehead of a user, and is capable of elastically retracting and retracting elastically, so that the frontal pad can be comfortably applied to different users, and the mask can be worn. The correctness.

"Snoring" is caused by obstruction of the upper airway. Causes such as obesity, degeneration of old age, and upper airway stenosis. These patients will collapse due to muscle relaxation in the throat, making the air unable to enter the lungs smoothly. The blood oxygen concentration is too low. At this time, the brain will feel hypoxia and command the body to breathe hard. This will cause a short-term recovery and will not enter the sleeping period smoothly. Sometimes it can happen dozens of times or even hundreds of times a night. Suffering from the so-called "sleep apnea", it will cause the patient to be in a state of waking up and sleep all night, unable to enjoy quality sleep quality, indirectly causing headaches during the day, easy to sleepiness or dozing, pay attention Inability to concentrate, memory loss, anxiety, personality changes, decreased sexual desire, etc., while at night there are snoring, frequent urination, etc., and easily lead to cardiovascular-related diseases.

In general, the treatment of "sleep apnea" mentioned above can be improved by exercise, weight loss, side sleeping, avoiding drinking before going to bed, taking sleeping pills, wearing a snoring device (bristles), etc., but if the condition is serious, It is necessary to use surgical treatment or non-invasive positive pressure breathing apparatus. The positive pressure breathing apparatus is used with a mask, which can achieve more than 90% of the treatment effect. It is used to wear a mask when sleeping, by means of a respirator. The pressure is generated to support the soft airway to maintain the smoothness of the respiratory tract, but up to 3 to 40% of patients may suffer from air leaks, mask pressure, resistance to exhalation, weight of the tubing, airflow drying, and inconvenience of carrying. And every It must be continued for at least 4 hours in the evening to achieve the therapeutic effect, and then give up treatment halfway.

Therefore, in addition to the weight of the appliance, portability, inspiratory resistance and other issues, continuous improvement and update, the intention to use the patient is the most important key to treatment, how to make the user who is turning over during sleep, wearing a breathing mask No rotational displacement occurs, except that the straps on both sides of the mask are tightened to achieve a good close-fitting airtightness between the mask and the face, and in order to maintain a positive pressure inside the mask, the mask needs to be closely attached. It fits around the patient's mouth and nose, but if the mask is too much pressure on the nose and mouth, it will cause discomfort.

Therefore, there is a structural design that disperses the pressure from the forehead and around the nose and mouth, such as the patent shown in US6467483, US5243971, etc., that is, the stent is extended at the upper end of the mask, and the end of the stent is extended. There is a frontal pad component that can be attached to the forehead, and a headband is provided on both sides of the frontal pad component, so that the headband can be tightly attached to the user's head, thereby allowing the sides of the mask to be covered, as well as above. The support of the three points is fixed, and the bracket can ensure that the mask always maintains a vertical orientation of 90 degrees with the wearer's face without rotating the displacement, thereby maintaining a good tightness between the mask and the face without leaking. .

However, because the mask, the frontal pad component and the bracket are both in an unadjustable fixed type, the actual adjustment cannot be made according to the adjustment of the forehead and face type of different users, thereby causing the forehead component to be unable to The user's forehead fits, in addition to air leaks that cause insufficient air pressure, which can cause discomfort during wear.

The reason is that in order to improve the above-mentioned conventional mask forehead support, there is no adjustment ability and it cannot be provided to various users. The present invention provides a method for automatically retracting and retracting at the upper end of the bracket portion of the mask. Forehead parts, when worn by different users, the frontal pad components can be properly attached to the forehead without the need for adjustment, and the mask can be worn in the correct position.

The solution of the present invention is to provide a bracket portion at the upper end of the cover, and an upper pad member having a frontal pad is disposed at the upper end of the bracket portion, wherein the upper end of the bracket portion is provided with a hole end having a smaller diameter. The inner edge portion of the inner diameter portion accommodates the hole portion, and the frontal pad member includes a front end portion of the frontal pad extending from a portion of the outer edge of the forehead, and a tube portion having a hole therein, and the tube portion is extended. The receiving hole portion is configured such that the engaging portion can abut against the inner edge portion, and an elastic member capable of outwardly elastically pushing the frontal pad member is disposed in the receiving hole portion.

Therefore, the headband provided on both sides of the bracket portion of the present invention and the straps on both sides of the mask form a three-point fixed support state to fix the mask cover, and the face shield member can be automatically advanced and retracted by the front and rear elastics. It is suitable for different users with flat or convex forehead, which ensures the correctness of the mask and reduces the pressure on the nose bridge to improve the wearing comfort.

Therefore, the present invention can be fully understood by the following embodiments in conjunction with the accompanying drawings, and is implemented accordingly:

Referring to FIG. 1 to FIG. 3 , the present invention is a bracket portion 11 extending upward from the nose bridge of the respiratory mask 1 , and a receiving hole portion 10 is disposed at the end of the bracket portion 11 , and the hole portion is accommodated. 10 is provided on both sides of the belt 10 for wearing the headband, and a frontal pad member 2 for supporting the forehead of the user is mounted on the receiving hole portion 10, and the bracket portion 11 and The receiving hole portion 10 and the frontal pad member 2 form a forehead receiving device.

The above-mentioned frontal pad member 2 is a tube portion 21 including a front side of the frontal pad 23 and having a hole 20 in the middle thereof, and the tube portion 21 is divided into elastic sheets. A plurality of flaps are formed, and a buckle abutting portion 22 is protruded from an outer edge of the end portion of the tube portion 21, and a tube portion 21 is provided at a hole end of the receiving hole portion 10 provided at the upper end of the bracket portion 11. The end buckle portion 22 forcibly passes through the inner edge portion 12 having a smaller inner diameter (as shown in FIG. 3), and then a pair of the mat surface member 2 is disposed between the tube portion 21 and the receiving hole portion 10. The outer elastically pushed elastic element 3.

Therefore, the headband is worn through the wearing straps 13 on both sides of the bracket portion 11, so that the upper end of the mask 1 can be fixed, and the straps on both sides of the mask 1 are added to form a three-point fixed support mask 1 Keeping it in the correct position without being offset, as shown in FIG. 4, the forehead member 2 provided by the upper end of the bracket portion 11 can be elastically stretched forward and backward elastically, so that the forehead is flat or More convex, the frontal pad member 2 is pushed or compressed by the inner elastic member 3, and automatically protrudes against the forehead of the flat person, or automatically retracts against the forehead of the convex person. In addition, not only can the correctness of the mask 1 be ensured, so as to prevent air leakage, and the pressure on the nose bridge of the mask 1 can be reduced, and the different users can be adjusted without having to adjust the frontal pad component 2 Get the correct and comfortable mask 1 to wear.

Although the above embodiments have disclosed and described the preferred embodiments of the present invention, they are clearly understood by those skilled in the art, and the various changes in the various types and methods are not Leaving the spirit and scope of this new type.
