Description of the new model: [Technical field to which the new model belongs] The new model relates to a breathing mask, particularly a medical breathing mask. [Previous technology] In the holistic treatment place, the respiratory mask is often covered in the nose and mouth for critically ill patients to assist the patient in breathing or to inject therapeutic gas with the breathing to maintain the normal physiological function of the patient. Referring to Figures 丨 and ~ 2, a conventional breathing mask 1 is shown, which has a body 11 and an air inlet 12 formed on the top of the body n. A strap fastening projecting from the outer periphery of the body 11 at an evenly spaced interval from the outer periphery of the body 11 The portion 13 and a flexible cushion 16 connected to the bottom edge of the main body u to contact the user's face. All the strap fixing portions 13 have openings through which the straps 14 (shown as imaginary lines) can pass. Taking the supply of oxygen as an example, the breathing mask 丨 communicates with an oxygen cylinder (not shown) through a catheter 15 to pass oxygen through the breathing mask 1 into the patient's respiratory tract. Due to the individual differences in the patient's face contour, it is particularly 疋 7T. The difference between the contours and the vicinity of the upper fender makes the breathing mask 1's jealous pad 16 slightly flexible, but often cannot fit the patient's face shape properly, resulting in the bottom of the respiratory mask 1 corresponding to the upper jaw and the patient's face. A gap of gas leakage is formed between them. In addition, because of the air tightness problem of the breathing mask i, the milk cannot be completely adhered to the contour of the face, resulting in poor use comfort. [New content] Therefore, the object of the present invention is to provide a breathing mask that can improve the degree of fit to the contour of the face, and & air tightness and comfort. M280814 Therefore, this new type of breathing mask includes a cover, a curved soft palate, and an air inlet connected to the cover of the cover to feed people with gas. In use, the cover covers the user's face and injects gas through an air inlet thereon. The cushion has a top edge that is in contact with the bottom edge of the cover and is direct: it touches the user's face and communicates with the internal space of the cover. The cushion has a medial surface, a The surface is opposite to the outer surface: and a deformed groove formed by the outer surface facing the inner surface or the _ surface facing the outer surface.

" The top edge 疋 of the cushion 22 is connected to the bottom edge of the cover 21 and communicates with the internal space 21 (). The deformation groove 223 extends a predetermined distance from the circumference of the dome-shaped cushion 22. This embodiment The middle-shaped k-groove 223 is substantially u-shaped on the dome-shaped cushion 22. The gas pipe 23 has a first section 231 connected to the air inlet 2m of the casing 21, a second section 232 extending from the free end edge of the -section 231 perpendicularly to the length of the first section 231, and a An exhaust hole 233 is formed on the outer side of the junction of the first and second sections of the 23m disc 232. The exhaust hole 233 can release a part of the gas in a direction opposite to the gas transport direction, so that the force on the breathing surface is maintained at a pre-δ value. The first and second sections 231 are connected in conjunction with the addition ^ The second section / 32 is connected to the ventilator to conduct positive dust gas into the second room 210 and infuse it into the user's respiratory tract. The buckle early 24 includes three grooves 形成 formed on the wall surface of the bottom edge of the cover at intervals, and protruding from the soft pad 22 toward the cover 21 respectively. In the corresponding groove 241, the cover shout 21 and the cushion 22 are fastened to each other into one body. The 4th structure! The strap fixing part 25 is an ear structure extending horizontally outward from the bottom edge of the cover 21, providing 'each of the strap fixing straps 25 are formed through M280814 251 KM "3 (shown in Figure 5) is worn and wrapped around the patient The head enables the entire breathing mask 2 to be fixed to the patient's nose. _When the breathing mask 2 is connected in series with the stern machine to form a communicating gas flow path, the entire breathing mask 2 can be covered on the patient's nose When covering, the bottom edge of the soft palate 22 corresponding to the position of the deformed groove 223 on the cushion 22 is aligned with the upper position of the patient. Because the upper jaw of the female patient (equivalent to between the nose and upper lip, to narrate The line table 7F) is exactly the same as the nose shape and angle position *. The soft palate 22 is made of a flexible material. When the cushion 22 covers it, the upper jaw will compress the cushion 22. If the patient's upper jaw contour is more prominent, the pressure on the cushion 22 formed by the exposed bone is greater, and this compression force can force the deformation of the right palate 22, especially in the most fragile part of the structure, that is, the deformation groove Slot 223 4 '俾 can conform to the contours of the patient to provide-airtight cover ^ the deformation groove 223 provides a deformation regulation area, so that the deformation caused by compression is concentrated here, and the other parts of the soft palate 22 will not form relative deformation, ensuring that the bottom edge of the cushion 22 can fit snugly on the upper skin. The positive pressure gas from the ventilator will not emerge from the skin and the bottom edge of the soft palate 22, so it has better air tightness than the conventional products. ^ In addition, the new model is more suitable for the first and second sections of the gas pipe 23. An exhaust hole 233 is formed at the junction of 231 and 232. The exhaust holes shown in FIGS. 3 to 5 are semicircular. This is the best aspect of this embodiment. In other embodiments, the exhaust hole The 23U can be circular or polygonal, but after many tests, the creator found that the semi-circular exhaust hole 233 has the best noise reduction effect. M280814 On the other hand, the extension length of the deformation groove 223 also affects the deformation The range of the adjustment zone. If the deformation groove 223 only extends in the length direction and does not form a U-shaped surround, the deformation adjustment zone is concentrated at the upper jaw. However, if the deformation groove 223 is extended to u%, the deformation can be deformed. The extent of the adjustment zone is extended to the sides of the nose ', in other words, according to the deformation The range of the adjustment zone is different. The breathing mask 2 provides various degrees of deformation, resulting in a variety of deformation selectivity, but whether the deformation groove 223 is concave from the inner surface 221 to the outer surface, that is, recessed from the inside to the outside, or The depression from the outer surface 222 to the inner surface 221, that is, the depression from the outside to the inside, has the same deformation adjustment capability. See FIG. 6 for another preferred embodiment of the new type breathing mask 2. The structure and configuration of this embodiment The difference between the front-embodiment is only the arrangement and shape of the exhaust hole 234. At the junction of this embodiment, when the first and second sections 231 and 232 are formed, the 'junction' will form an unclosed Half-moon-shaped exhaust holes 234 are arranged on the outer side of the L-shaped turning point and extend above the edge of the second section 232 of the breast milk officer 23, so that the exhaust holes 234 can face the beer The exhaust direction of the inhaler, that is, the exhaust direction of the row button 234 is parallel to the extending direction of the second section 232 of the gas pipe 23. Because the position of the exhaust hole 234 restricts the air direction, the gas can only be discharged toward the respirator. , Compared to the previous implementation Gas is directly discharged can be avoided and noise which affects Sleeping by 'reducing sleep disturbance accompanying the use respirator comes a further embodiment of the improvement reached in the present embodiment. Summarizing the above, the new type of breathing mask 2 has a deformed M280814 groove 223 on the soft palate 22, so that when the breathing mask 2 is covered on the nose, it can conform to the deformation of the upper jaw and the circumference of the nose. Does not affect the original cushion 22, ',. It can make the bottom edge of the soft palate 22 easier to adhere to the patient's face in an air-tight manner, cooperate with the far-exhaust pores 233 and 234 to effectively exhaust the gas, and reduce the occurrence of this disease as much as possible, so it can indeed reach the new type The purpose of the appeal. The above-mentioned ones are merely preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited in this way, that is, any simple equivalent changes and modifications made according to the patent application of the new application and the description of the new application, all Still within the scope of this new patent.
