DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0025] like Figure 1-4 As shown, the convertible nasal mask includes a main mask body 1, which is provided with a first air supply cavity 2 for covering the human nose. The lower side of the main mask body 1 is open to form a mounting area 3, and an elastic closing film 4 is installed at the mounting area 3. The closing film 4 is used to close the mounting area 3. An elastic strip 5 is provided at the edge of the closing film 4, and the elastic strip 5 is used to resist the human body and drive the closing film 4 to close the first air supply cavity 2.

[0026] Preferably, a sub-cover body 6 is further included, which is arranged corresponding to the lower end of the main cover body 1 and is movably connected to the main cover body 1, and a second air supply cavity 7 for covering the human mouth is provided on the sub-cover body 6. A connecting rod 8 is provided in the sub-cover body 6 and a traction surface 9 is fixedly connected to the connecting rod 8. The traction surface 9 and the elastic strip 5 are respectively provided with a first magnetic part 10 and a first adsorption part 11, and the first magnetic part 10 is used to magnetically connect the first adsorption part 11 to separate the elastic strip 5 from the human body to form an air supply gap 12.

[0027] Preferably, a connecting unit 13 is further included, and the main cover body 1 and the auxiliary cover body 6 are connected to the human body through the connecting unit 13.

[0028] When in use, the main cover body 1 and the auxiliary cover body 6 are connected to the human face through the connecting unit 13. At this time, the traction surface 9 corresponds to the elastic strip 5, so that the elastic part is pulled apart from the human body by the mutual adsorption of the first magnetic part 10 and the first adsorption part 11, so that the first air supply cavity 2 and the second air supply cavity 7 are connected to each other, so that the main cover body 1 and the auxiliary cover body 6 can be used together as a mask.

[0029] When the device needs to be converted, the traction surface 9 and the elastic strip 5 can be separated from each other by flipping or moving the auxiliary mask body 6 downward, so that the elastic strip 5 contacts the human body again under the action of its own elastic force, thereby realizing the conversion of the nasal mask. At the same time, the separation of the auxiliary mask body 6 opens the human mouth to facilitate subsequent operations.

[0030] Due to the use of magnetic adsorption traction, the overall structure is simple and reliable, and the size is compact, which is convenient for clinical use.

[0031] Preferably, a wavy connecting layer 14 is provided at the edge of the installation area 3, and the connecting layer 14 is made of rubber. A second magnetic part 15 and a second adsorption part 16 are respectively provided on the side where the auxiliary cover body 6 and the connecting layer 14 are close to each other. The second magnetic part 15 is used to magnetically connect the second adsorption part 16 to connect the auxiliary cover body 6 and the connecting layer 14 to each other.

[0032] When in use, the wavy connecting layer 14 allows the auxiliary cover body 6 to be flipped to provide a larger range of movement. At the same time, the auxiliary cover body 6 can be directly separated by the provision of the second magnetic member 15 and the second adsorption member 16 to further facilitate mouth operation.

[0033] Preferably, the connecting unit 13 includes two groups of elastic bands, which are arranged crosswise, and two ends of the elastic bands are respectively connected to the main cover body 1 and the auxiliary cover body 6.

[0034] The cross-arranged elastic bands can provide a better fixing effect, and at the same time the structure is simple and easy to use.

[0035] Preferably, a connecting portion 17 is provided on the auxiliary cover body 6, one end of the connecting rod 8 is connected to the traction surface 9, and the other end is movably connected to the connecting portion 17 to adjust the height of the traction surface 9 relative to the human body surface.

[0036] By adjusting the height of the traction surface 9, the position of the elastic strip 5 can be adjusted in coordination with the magnetic connection between the first magnetic member 10 and the first adsorption member 11, thereby adjusting the size of the air supply gap 12 to adapt to the facial curves of different human bodies.

[0037] Preferably, a limiting hole 18 is provided on the connecting portion 17, and the connecting rod 8 is slidably connected to the limiting hole 18. The limiting hole 18 is used to limit the connecting rod 8 to move only along the axial direction of the limiting hole 18, and the connecting rod 8 and the limiting hole 18 are interference fit, that is, the position of the connecting rod 8 relative to the limiting hole 18 is fixed by the mutual friction between the connecting rod 8 and the limiting hole 18.

[0038] Limiting the connecting rod 8 by the limiting hole 18 can avoid the misalignment of the traction surface 9 and the elastic strip 5 caused by the deviation of the connecting rod 8, and also facilitates the operator to adjust the connecting rod 8 as needed.

[0039] Preferably, both sides of the elastic strip 5 extend outward to form an extension portion 19, and a notch 20 is formed in the main cover body 1 corresponding to the extension portion 19. A limiting unit 21 is provided at the notch 20. The limiting unit 21 is used to resist the limiting extension portion 19 to limit the extension portion 19 from rebounding toward the first air supply chamber 2. The limiting unit 21 includes a mounting rod 22 and a roller 23. The mounting rod 22 is made of plastic and is fixed to the incision. A mounting hole is formed on the roller 23 and is interference fit with the mounting rod 22. Matching grooves 24 are circumferentially arranged on the surface of the roller 23. The extension portion 19 is provided with a plurality of matching blocks 25 along the length direction that are mutually engaged with the matching grooves 24.

[0040] During use, after the traction surface 9 is separated from the elastic strip 5, when the elastic strip 5 rebounds and has poor adhesion to the human body, the extensions 19 on both sides are pulled so that the matching blocks 25 come into contact with the matching grooves 24, thereby achieving traction on the extensions 19 through the friction between the rollers 23 and the mounting rods 22, thereby keeping the elastic strip 5 in a stretched state to avoid poor adhesion. At the same time, when the human mouth moves and pulls the elastic strip 5, the elastic strip 5 can obtain further mobility through the rotation of the rollers 23 to ensure both sealing and mobility.

[0041] Preferably, the main cover body 1 and the auxiliary cover body 6 are provided with grooves at the bottom and soft silicone 26 is installed in the grooves. The soft silicone 26 can ensure the sealing effect of the bottom edges of the main cover body 1 and the auxiliary cover body 6, and can also achieve flexible contact with the human body, thereby avoiding the occurrence of pressure sores.

[0042] Preferably, an air inlet 27 and an air outlet 28 are provided on the main cover body 1.

[0043] Specifically, the main mask body 1 is connected to the ventilator through the air inlet 27, and discharges the gas exhaled by the patient through the air outlet 28. In addition, the gas discharged from the air outlet 28 can be disinfected by an external disinfection device.

[0044] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
