Problems solved by technology

As the name suggests, a full-face mask will cover and seal the wearer's mouth and nose features at the same time during treatment, resulting in some insurmountable defects in the full-face mask itself, for example, it needs to cover the wearer's nose when worn And the mouth, so the overall will be more bulky, and it will seriously affect the wearer's field of vision when worn; in addition, covering the wearer's nose will also oppress the wearer's sensitive nose bridge area, and is not friendly to the wearer who suffers from claustrophobia etc., these may lead to the resistance of the wearer

Embodiment 1

[0104] see figure 2 The nose 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 wearer's nostrils in response to the oronasal liner 1 being put on by the wearer, and fits around the wearer's nostrils through the nose cushion portion 22. together to seal.

[0105] Specifically, referring to FIG. 5 , the nose cushion portion 22 includes a middle portion 23 arranged around the nose opening 21 and a first side support portion and a second side support portion arranged on both sides of the middle portion 23 , because the first side support The first side support part and the second side support part can be configured according to the same structure, so hereinafter, the first side support part and the second side support part will not be distinguished, but are collectively referred to as the two sides of the nose part 24....

Embodiment 2

[0140] On the basis of the above-mentioned embodiment 1, the present invention provides a modified embodiment, embodiment 2, as shown in Figure 12- Figure 15 shown.

[0141] 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.

[0142] For example, the material of the mouth and nose liner 1 can be one or more of materials such as silicone rubber, foam, thermoplastic elastomer, thermosetting material, foam, resin and textile.

[0143] When the material of the mouth and nose liner 1 can be silicone rubber, it is preferably silicone rubber with a Shore hardness of 30-40.

Embodiment 3

[0145] 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.

[0146] Please refer to Figure 16 , 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 plurality of exhaust holes 61 provided on the oronasal liner 1 .

[0147] 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. Preferably, the exhaust hole 61 is in the shape of a strip, which can have a larger single hole area on the narrower surface in the exhaust direction, so that when the total exhaust is an expected constant value, the number of holes can be achieved. At least, it can also reduce the noise an...

Abstract

The invention relates to a mouth-nose pad and a patient interface device, and relates to the technical field of treatment of respiratory related diseases. According to the mouth-nose pad, due to the fact that a nose opening in a nose structural body surrounds the lower sides of the nostrils of a wearer for ventilation, the mouth-nose pad does not need to cover the nose of the wearer, the size of the mouth-nose pad can be reduced on the whole, and the mouth-nose pad is smaller, lighter, not prone to generating claustrophobia and more comfortable to wear. A nose cushion part is adaptively attached to the periphery of the nares of the wearer for sealing, so that the nose wing of the wearer is not clamped, the wearing comfort is further improved, and the treatment effect and treatment compliance of the wearer can be improved. Besides, the nose structural body and the mouth structural body are respectively constructed, so that the inner cavity can bear higher pressure to meet the treatment requirements of different symptoms.

Description

technical field [0001] The invention relates to the technical field of treatment of respiratory-related diseases, in particular to an oral and nasal cushion and a patient interface device. Background technique [0002] Respiratory-related diseases are accompanied by a spectrum of respiratory disturbances characterized by apnea, hypopnea, and hyperpnea. Examples of respiratory diseases include obstructive sleep apnea (OSA), respiratory insufficiency, obesity, chronic obstructive pulmonary disease (COPD) and other diseases. For the aforementioned respiratory diseases, generally a patient interface device, or mask, is used for treatment. [0003] Judging from the currently known clinical data combined with the general equipment usage, full-face masks are the wearer interface configuration with a higher usage rate. As the name suggests, a full-face mask will cover and seal the wearer's mouth and nose features at the same time during treatment, resulting in some insurmountable ...
