If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] like Figure 1-Figure 6As shown, a multi-layer humidification mask for a non-invasive ventilator includes a contoured cover plate 1 that can be placed on the patient's mouth and nose, an air cushion assembly is provided on the side of the contoured cover plate 1 facing the patient's mouth and nose, and a multi-layer shield assembly is hinged on the other side of the contoured cover plate 1; the multi-layer shield assembly includes a plurality of arc panels 2 that are hinged to each other and can be buckled in sequence to form a mask structure, and an air inlet pipe 3 for connecting to the ventilator is provided on the arc panel 2; wherein, the air inlet pipe 3 is provided with an external sieve hole 301 that can be connected to the atomized liquid.

[0029] Specifically, before the patient wears the mask, the air cushion assembly is inflated so that when the patient wears it, the mask can effectively fit the patient's face shape and reduce the risk of facial pressure trauma. And when the patient needs to eat, drink water, oral care and suction sputum, etc., one of the curved panels 2 can be selectively opened without removing the entire mask, which is convenient for medical staff or family members to assist the patient in drinking water, eating, suctioning sputum, etc. At the same time, the external sieve hole 301 set on the air inlet pipe 3 can be connected to an external atomized liquid medicine or atomized pure water, etc., so that the non-invasive ventilation patient can take in water, relieve the symptoms of dry mouth, increase the humidification rate of the patient's breathing, and prevent the formation of sputum crusts and cause the patient's disease to worsen. The use of the mask in this technical solution not only improves the comfort of the patient for some patients who breathe with their mouths open, have dry mouths, and are unable to cough up sputum, but also effectively reduces the infection rate of the patient, shortens the treatment cycle, and reduces the patient's hospitalization cost. At the same time, in the above, the external sieve hole 301 can choose to use a structure such as a quick interface in the prior art, which can ensure its airtightness while also being able to quickly connect to other pipes for introducing atomized liquid medicine and atomized pure water.

[0030] The above, such as Figure 1 , Figure 2 , Figure 4 As shown, the air cushion assembly includes an annular air cushion 4, and a valve core 5 for inflating and deflation thereof is provided on the annular air cushion 4. The annular air cushion 4 is inflated and deflated by the valve core 5, so that when the patient wears the mask, the annular air cushion 4 can better fit the patient's face, ensuring the effect of non-invasive ventilation, and can also reduce the pressure on the patient's face, thereby improving the comfort of the patient when wearing the mask.

[0031] The above, such as Figure 5As shown, the air cushion assembly includes a plurality of arc-shaped air cushions 6, each of which is provided with a valve core 5 for inflating and deflating the air. The plurality of arc-shaped air cushions 6 can be connected in sequence to form a structure similar to the annular air cushion 4, except that each valve core 5 thereon is connected to a separate air chamber. Facing patients with different face shapes, by adjusting the air pressure in different arc-shaped air cushions 6, the arc-shaped air cushion 6 can be perfectly fitted to the patient's face. Furthermore, the position of the valve core 5 in the present technical solution can be set on the arc-shaped air cushion 6 or the annular air cushion 4 at a position facing away from the patient's face, or can be embedded in the arc-shaped air cushion 6 or the annular air cushion 4 at a position facing the patient's face, so as to avoid the valve core 5 leaving an indentation on the patient's face or even crushing the patient's face.

[0032] In this embodiment, if Figure 6 As shown, an interlayer 7 is provided on the inner side of the arc-shaped air cushion 6 and / or the annular air cushion 4 close to the patient's face, and a water-absorbing cotton strip exposed within the patient's mouth and nose is provided in the interlayer 7. When the patient breathes, liquefied water droplets will inevitably form on the inner wall of the mask. The water-absorbing cotton strips provided in the interlayer 7 can absorb the water droplets sliding along the inner wall of the mask to prevent the water droplets from falling on the patient's face, thereby effectively avoiding symptoms such as peeling, pain, infection, eczema, and blisters on the patient's face. At the same time, through the elasticity of the interlayer 7 itself, the water-absorbing cotton strips can be stably clamped after the arc-shaped air cushion 6 and the annular air cushion 4 are inflated to prevent the water-absorbing cotton strips from falling off. At the same time, after the arc-shaped air cushion 6 and the annular air cushion 4 are deflated, new water-absorbing cotton strips can be easily replaced. The mask can be reused after disinfection, saving medical resources.

[0033] Further, such as Figure 3 As shown, in order to prevent the curved panel 2 from accidentally opening when the patient's head moves and affecting the patient's non-invasive ventilation, a buckle assembly 8 for connection is provided between two adjacent curved panels 2 and between the curved panel 2 and the contoured cover plate 1. Preferably, the buckle assembly 8 in the present technical solution can use the buckle structure commonly used in the prior art, that is, long buckles, spring buckles, adjustable buckles, luggage buckles, etc. In the present technical solution, a snap-on structure 9 for connection is provided between the above-mentioned two adjacent curved panels 2 and between the curved panel 2 and the contoured cover plate 1. The curved panels 2 and the curved panels 2 and the contoured cover plate 1 can also be connected through the snap-on structure 9. Different from the buckle assembly 8, the snap-on structure 9 can be integrally formed with the curved panel 2 or the contoured cover plate 1, which can reduce the production process and production costs. The specific structure is as follows Figure 3As shown, taking the snap-fit ​​structure 9 on the curved panel 2 and the contoured cover plate 1 as an example, it includes but is not limited to, both the curved panel 2 and the contoured cover plate 1 are provided with snap-fit ​​plates, and the corresponding two snap-fit ​​plates are provided with snap-fit ​​recesses and snap-fit ​​protrusions, wherein the snap-fit ​​protrusion on one of the snap-fit ​​plates can be elastically supported in the snap-fit ​​recess on the other snap-fit ​​plate, and in the absence of external force, the curved panel 2 and the contoured cover plate 1 can be effectively connected together by relying on the elasticity of the snap-fit ​​plate itself.

[0034] The above, such as Figure 3 As shown, in order to enhance the air tightness of the connection between two arc panels 2 and between the arc panel 2 and the contoured cover plate 1, a rubber sealing pad 10 is provided between two adjacent arc air cushions 6 and between the arc air cushion 6 and the contoured cover plate 1.

[0035] Furthermore, in this technical solution, if Figure 1 As shown, a hanging seat 101 for hanging a restraining belt is provided on the contoured cover plate 1, which is used to set the restraining belt on the mask.

[0036] Further, such as Figure 1 , Figure 6 As shown, the arc-shaped air cushion 6 and / or the contoured cover plate 1 are provided with a plug hole 11 for inserting an oxygen tube, and the arc-shaped air cushion 6 and / or the contoured cover plate 1 are provided with a rubber plug 12 that can be plugged into the plug hole 11. Medical equipment such as an oxygen tube can be inserted into the patient's nostrils through the plug hole 11, so as to ensure the normal oxygen supply to the patient when assisting the patient to eat or drink water.

[0037] Working principle: Before the patient wears the mask, the annular air cushion 4 or the arc-shaped air cushion 6 is inflated so that when the patient wears it, the mask can fully fit the patient's face shape, reducing the risk of pressure trauma to the patient's face. At the same time, when the patient needs to eat, drink water, oral care and suction sputum, one of the arc-shaped panels 2 can be selectively opened to facilitate medical staff or family members to assist the patient in drinking water, eating, suctioning sputum, etc. The whole process does not require the entire mask to be removed, avoiding frequent removal of the mask, improving the discharge of lung residual volume, and helping the patient to improve oxygenation. At the same time, the external sieve hole 301 set on the air inlet pipe 3 can be connected to an external atomized liquid medicine or atomized pure water, so that the non-invasive ventilation patient can take in water, relieve dry mouth symptoms, increase the humidification rate of the patient's breathing, and prevent the formation of sputum crusts and worsening of the patient's disease.

[0038] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
