New description: [New technical field] This creation is about the improvement of a respiratory mask structure, especially a breathing apparatus that can simultaneously make the gas only go out at the exhaust port and only enter the air inlet. Structural improvement. [Prior Art] Obstructive sleep apnea syndrome is a symptom of airway obstruction caused by collapse of the respiratory tract during sleep. For treatment, continuous positive airway respirator is now used. Airway pressure (CPAP), which uses a gas supply table with adjustable airflow pressure, can drive a certain pressure of gas into the respiratory mask through the trachea, helping the patient to keep the airway open and breathing smoothly during sleep. Sleep apnea can also help improve the snoring during sleep. There are three problems in the breathing hood of the prior art: 1. A venting hole is provided in the breathing hood to discharge the gas that the user is drinking, but the design of the venting hole also causes the external body to flow in. , reducing the pressure inside the breathing hood, thus also reducing the efficiency of the airway. 2. If the vent hole is not provided, the gas volume will be stored in the breathing hood, causing the user to breathe. The gas that is exhaled by #周回回流流流, and affects the supply of positive pressure gas. 3 M394134 The abutment of the respirator will abut against the forehead and strengthen the fixation of the respirator'. However, the conventional abutment bracket cannot be bent at multiple angles, causing the abutment to not fit the appropriate face to the appropriate If the problem cannot be solved, it will cause inconvenience in the use of the respiratory mask. In view of this, the creators of this case have researched and developed with years of research experience.

[Embodiment] In order to more clearly describe a respiratory mask improvement proposed by the present invention, a preferred embodiment of the present invention will be described in detail below with reference to the drawings. . Please refer to the first figure, the second figure and the third figure at the same time, which are respectively a three-dimensional expansion diagram of the preferred embodiment of the present invention, a first perspective view and a second perspective view, The utility model comprises: a cover body 1, a gas pipe 2, a plastic support 3 and an abutting portion. The mask has a plurality of exhaust ports 11, and the internal gas of the mask body i can pass through the exhaust port 11 Discharge; - group one-way reading 12, sighing above the exhaust port 11 'the set of check valves 12 can discharge the internal gas 'and prevent external gas from entering; an air inlet 13 is a gas entry An entrance of the mask body 1; a bracket connecting portion 14 is disposed at an upper end of the mask body 1 near the exhaust port U; and a set of strap connecting portions 15 for connecting a headband (not shown) The belt surrounds the head and assists the mask body [5 M394134 fixed; 13 ' is the gas check valve 23 when the external air is introduced, which prevents the air tube 2 from being connected to the air passage of the air inlet. One of them, the trachea 2 can be removed to facilitate the replacement of gas. The gas flows out of the mask body by the air pipe 2, and is interpreted as a first pipe member 21 and a second pipe member 22 return valve 23; a Dan end is connected to the bracket and the plastic bracket can be bent and positioned at various angles; The abutting portion 4 is configured to be coupled to the other end of the plastic stent 3 when the mask is attached, and a set of soft jaw members 421 is disposed on a second surface 42 thereof. The set of soft palate elements 421 can be a set of airbags to help the abutment portion 4 to increase comfort when resisted. Please refer to the fourth figure, which is a schematic view of the trachea deployment of the preferred embodiment of the present invention. In the preferred embodiment, the gas 23 is a cone and has a The gas end and the exhaust end, for example, use the area of the intake end 231 to be larger than the area of the exhaust end to cause the intake pressure of the intake end 231 to be greater than the exhaust pressure of the exhaust end to prevent internal gas. The effect of the trachea 2 flowing out of the mask body. The above has made a fairly complete disclosure of the present invention. In summary, it can be seen that the present invention has the following advantages: L. The one-way valve piece 12 is designed to solve the problem that external gas flows into the respiratory hood from the vent hole of the respiratory mask. In turn, the problem of breathing the internal pressure of the grass 6 M394134 is reduced. 2. The design of the gas check valve 23 prevents the gas exhaled by the user from flowing back through the trachea 2, affecting the supply of positive pressure gas. 3. The structural design of the plastic bracket 3 can be bent and positioned at various angles, so that the abutting portion can be matched with different face shapes, and the breathing cover can be assisted against the appropriate part to improve the comfort of the abutted portion. However, the above detailed description is intended to be illustrative of the specific embodiments of the present invention, and is not intended to limit the scope of the present invention. The patent scope of this case.
