Embodiment 1

[0126] see figure 2 , the nasal structure 2 includes a nasal opening 21 communicating with the cavity 6 and a nasal cushion portion 22 surrounding the nasal opening 21 . Wherein, the nose opening 21 is configured to surround the underside of the user's nostrils in response to the oronasal liner 1 being worn by the user, and the nose cushion part 22 is adapted to fit around the user's nostrils for seal.

[0127] Specifically, referring to FIG. 5 , the nose cushion portion 22 includes a middle portion 23 arranged around the nasal opening 21 and nose side portions 24 arranged on both sides of the middle portion 23 , and the middle portion 23 responds to the pressure in the cavity 6 . The increase deforms to fit around the user's nostrils. Among them, the thickness of the middle part 23 can be 0.2-1.0mm, that is, the area where the middle part 23 is located is a thin film area, so it will expand and deform when it is pressed so that it can be close to the user's nostrils, so ev...

Embodiment 2

[0161] On the basis of the above-mentioned embodiment 1, the present invention provides a modified embodiment, that is, embodiment 2, such as Figure 12-Figure 15 shown. The following will only describe its differences from the foregoing embodiments, and the similarities will not be repeated here.

[0162] The difference between this embodiment and embodiment 1 is that the reinforcement structure 4 is made of the same material as the mouth structure body 3, and the two form an integral body. The material of the nasal structure 2 can also be the same as that of the reinforcing structure 4 and the oral structure 3, that is, the oronasal liner 1 is made of the same material as a whole.

[0163] For example, the material of the mouth and nose liner 1 can be one of materials such as silicone rubber, foam, thermoplastic elastomer, thermosetting material, foam, resin and textile.

[0164] When the material of the mouth and nose liner 1 can be silicone rubber, it is preferably silic...

Embodiment 3

[0166] On the basis of the above-mentioned embodiments, the present invention provides a modified embodiment, that is, embodiment 3. The following will only describe its differences from the foregoing embodiments, and the similarities will not be repeated here.

[0167] Please refer to Figure 27 , The difference between this embodiment and the above-mentioned embodiments is that the upper front side of the oronasal liner 1 is configured with an exhaust assembly 60 . The exhaust assembly 60 includes a first body (exhaust portion). The vent part may be a plurality of vent holes 61 provided on the oronasal liner 1 . Wherein, the first main body is integrally formed with the mouth and nose liner 1 .

[0168] The exhaust hole 61 is in the shape of a strip, an oblong shape, a circle, an oval or a special shape and the like. More specifically, the projection of the exhaust hole 61 on the normal plane P1 is in the form of a long strip, an oblong shape, a circle, an ellipse, a rec...

Abstract

The invention relates to an exhaust assembly, a ventilation assembly and a mask system, and relates to the technical field of treatment of respiration-related diseases. When the mask system is worn, the nostrils and the mouth of a user are covered with a nose structural body and a mouth structural body respectively, so that the requirement for mouth breathing can be met, and the mask system has the advantage of being good in clinical gas blood parameters; and meanwhile, due to the fact that the mask system is sealed around the nostrils of the user, the two sides of the nose bridge or the nose wings of the user are prevented from being pressed, the mask system is smaller and lighter in structure and better in visual field, the comfort degree is improved, and compared with a full-face mask, the nasal mask is not prone to generating claustrophobia and has better crowd adaptability. Therefore, the mask system not only can overcome the defects of poor comfort and poor crowd adaptability caused by the fact that the nose bridge is easily pressed when an existing full-face mask is worn, but also can keep the advantages that the full-face mask can meet the mouth breathing requirement and is good in the clinical gas and blood parameters, and therefore the treatment effect and treatment compliance can be improved.

Description

technical field [0001] The invention relates to the technical field of treatment of respiratory-related diseases, in particular to an exhaust assembly, a ventilation assembly and a mask system. Background technique [0002] Chronic obstructive pulmonary disease (COPD) is a chronic bronchitis and / or emphysema characterized by airflow obstruction, which can further develop into a common chronic disease of pulmonary heart disease and respiratory failure. Continuous positive airway pressure (CPAP) therapy and non-invasive ventilation (Non invasive ventilation, NIV) are commonly used to treat the above respiratory diseases. The principle is to provide continuous positive airway pressure through the therapeutic device to keep the airway open and prevent upper airway obstruction. Nevertheless, patients may refuse treatment if they feel that the treatment device is uncomfortable, poorly usable, etc. [0003] The patient interface is an interface device worn on the patient's face d...
