1. Field of the Invention
The present invention relates to a respiratory mask, and in particular to an adjustable respiratory mask.
2. Description of Prior Art
Obstructive Sleep Apnea (OSA) is a sleep disorder caused by obstruction of the upper airway. It is characterized by repetitive pauses in breathing during sleep, and is usually associated with a reduction in blood oxygen condensation. Due to multiple times of sleep disturbance and low blood oxygen condensation, those who suffer from the OSA has greater possibility of suffering from cardiovascular diseases than normal people.
The most effective way of curing the OSA is to use a continuous positive airway pressure (CPAP) respirator, which comprises a mask and an air supply device connected to the mask. The mask includes a nasal cover, a forehead fixing base, and a supporting frame connecting the nasal cover and the forehead fixing base. By this arrangement, the air supply device continuously pumps the air into the nasal cover to generate a positive-pressure continuous airflow to the user. In this way, the upper airway of the patent can be kept unobstructed and the sleep apnea can be cured.
However, since the supporting frame between the nasal cover and the forehead fixing base is not adjustable, the supporting frame cannot be adjusted to correspond to the face contours of different users. As a result, the forehead fixing base cannot fit the forehead of the user. Further, the user who wearing such a mask will feel uncomfortable. Even, the oxygen gas may leak from the nasal cover, so that air pressure is insufficient.
In view of the above, the present Inventor proposes a novel and reasonable structure based on his expert knowledge and deliberate researches.
The present invention is to provide an adjustable respiratory mask, which has an adjustable support to adjust the distance between the nasal cover and the forehead fixing base. The adjustable support is a plastic piece and inclined relative to an upright frame, thereby adjusting the angle between the nasal cover and the forehead fixing base. In this way, the face contours of different users can be fitted, and the user wearing such a respiratory mask can feel more stable and comfortable.
The present invention is to provide an adjustable respiratory mask, including: a nasal cover comprising a frame assembly and a cover body, the frame assembly having an upright frame and an adjustable support extending from the upright frame, the upright frame being connected to the cover body, the adjustable support being a plastic piece and inclined relative to the upright frame; and a forehead fixing base having a base body, the base body being provided with a receiving portion, the adjustable support penetrating the receiving portion to allow the base body to adjustably move.
The present invention has the following advantageous features:
The adjustable support movably penetrates the receiving portion to thereby adjust the distance between the nasal cover and the forehead fixing base. The adjustable support is a plastic piece and inclined relative to the upright frame, thereby adjusting the angle between the nasal cover and the forehead fixing base. Thus, the respiratory mask of the present invention can fit the face contours of different users, and make the users to feel stable and comfortable when wearing it.
Further, the adjustable support is a plastic piece, so that the adjustable support can swing relative to the upright frame when the adjustable support is used. In this way, the angle between the nasal cover and the forehead fixing base can be adjusted to fit the face contours of different users. However, the plastic piece may suffer from an elastic fatigue after being used for a period of time, thereby memorizing the special face contour of the user, thereby making the user to feel more stable and comfortable when wearing it.
An engaging piece is engaged with any one of engaging troughs, thereby adjusting the distance between the nasal cover and the forehead fixing base via the adjusting support. Further, the angle between the nasal cover and the forehead fixing base can be adjusted, so that the forehead fixing base can be slightly adjusted in height besides its adjustment in the front-and-rear direction. In this way, the nasal cover and the forehead fixing base will more fit the face contour of the user, so that the cover portion can tightly cover the nose and mouth of the user to avoid the insufficient air pressure due to air leakage. Thus, the respiratory mask of the present invention has an increased stability in use.
Further, the respiratory mask of the present invention further includes a protective pad made of silicon or rubber. The protective pad is elastically sandwiched between the forehead fixing base and the forehead of the user. No matter the user wears the respiratory mask tight or loose, the protective pad can still provide a cushioning effect to the user, so that the user can feel more comfortable when wearing it.
The respiratory mask of the present invention further includes a connecting pipe and a head band. The head band is provided with a penetrating portion to form a space between the head band and the head of the user. By this arrangement, the connecting pipe can penetrate the penetrating portion to be fixed thereto easily without shaking Thus, the respiratory mask of present invention can be used more conveniently.
The detailed description and technical contents of the present invention will become apparent with the following detailed description accompanied with related drawings. It is noteworthy to point out that the drawings is provided for the illustration purpose only, but not intended for limiting the scope of the present invention.
Please refer to
The nasal cover 1 comprises a frame assembly 11 and a cover body 12. The frame assembly 11 has an upright frame 111 and an adjustable support 112. The upright frame 111 is provided on the periphery of the cover body 12. The adjustable support 112 is inclined relative to the upright frame 111. An angle (θ) is formed between the upright frame 111 and the adjustable support 112. The adjustable support 112 is a plastic piece, so that the adjustable support 112 can swing relative to the upright frame 111 and thus the angle (θ) is in a range of 90 to 270 degrees. The cover body 12 is made of silicon or rubber. The cover body 12 is provided with a first opening 121 and a second opening 122 opposite to the first opening 121. The upright frame 111 has a plurality of fixing portions 1111. The adjustable support 112 is provided with a plurality of engaging troughs 1121.
The forehead fixing base 2 has a base body 21. The base body 21 is provided with a protrusion 211. The protrusion 211 is provided with a through-hole 212 to form a receiving portion 213. The base body 21 is formed with an engaging piece 214 in the through-hole 212. The engaging piece 214 can be engaged with any one of the engaging troughs 1121, so that the adjustable support 112 penetrates the receiving portion 213 to allow the base body 21 to adjustably move. The base body 21 is provided with a plurality of through troughs 215 and a plurality of accommodating portions 216. Of course, conversely, the base body 21 may be also provided with a plurality of engaging troughs. The adjustable support 112 has an engaging piece engaged with any one of the engaging troughs.
The adjustable respiratory mask of the present invention further includes a protective pad 3 made of silicon or rubber, which will be described more detail as follows. The protective pad 3 has a plurality of engaging blocks 31. Each of the engaging blocks 31 penetrates the through trough 215 to be engaged therein. In this way, the protective pad 3 is fixed below the base body 21.
The assembly of the adjustable respiratory mask of the present invention will be described as follows with reference to
The adjustable support 112 is a plastic piece, so that it can swing relative to the upright frame 111 when in use. In this way, the angle (θ) between the nasal cover 1 and the forehead fixing base 2 can be adjusted, and the face contour of the user can be fitted. However, since the plastic piece may suffer from an elastic fatigue after being used for a period of time, it can memorize the special face contour of the user. Thus, the user can feel more stable and comfortable when wearing it.
