[0002] Respiratory masks are commonly used consumables in hospitals. Medical staff need to wear them to prevent infection and patients need to wear them when undergoing nebulization, oxygen inhalation, etc. To be specific, in order to better fit the facial contour, the material of the respiratory mask is mostly soft and elastic.
[0003] Although existing respiratory masks can provide good protection, if worn for a long time, the face is still prone to pressure injuries, which in turn cause pressure sores, especially the bridge of the nose. Since the nose is relatively prominent on the entire face and there is less soft tissue there, mostly hard bones, and most respiratory masks are mass-produced, the contour design of the bridge of the nose is fixed and cannot be customized according to the contour of each person's nose. This causes medical staff or patients to suffer pressure injuries on the bridge of the nose due to excessive vertical pressure or friction of the mask after wearing the respiratory mask for a long time, which in turn causes pressure sore symptoms, posing certain safety hazards.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figures 1 to 3 As shown, an embodiment of the utility model provides a medical breathing mask, comprising: a mask body 1, the mask body 1 is set to a flexible material, an elastic nose bridge pressure plate 2 is embedded in the mask body 1, a moving block 3 is fixedly installed in the middle of the nose bridge pressure plate 2, and is used to drive the nose bridge pressure plate 2 to reciprocate along a specified direction. A driving component is set on the mask body 1, and when the driving component is running, the driving component controls the moving block 3 to reciprocate along the specified direction.
[0025] The working principle and beneficial effects of the above technical solution are as follows: when it is necessary to adjust the contour of the mask body 1 near the bridge of the nose according to the actual situation of the wearer, the moving block 3 is driven to move by the driving assembly so that the moving block 3 moves along the axial direction of the threaded rod 5. When the wearer's bridge of the nose is more prominent, the moving block 3 is driven to move along the axial direction of the threaded rod 5 away from the wearer's face, and the moving block 3 drives the nose bridge pressure plate 2 to move synchronously. The two sides of the elastic nose bridge pressure plate 2 are bent by the resistance of the inner wall of the mask body 1. At the same time, the nose bridge pressure plate 2 squeezes the inner wall of the mask body 1, so that the contour of the mask body 1 near the bridge of the nose changes, reducing the pressure on the bridge of the nose. This embodiment adopts technical means of cooperating with the moving block 3 and the nose bridge pressure plate 2. The moving block 3 drives the nose bridge pressure plate 2 to move to change the contour of the mask body 1 at the bridge of the nose, reduce the pressure on the bridge of the nose, and thus eliminate the corresponding safety hazards.
[0026] In one embodiment: the driving assembly includes a fixed tube 4 and a threaded rod 5, the fixed tube 4 is fixedly connected to the mask body 1, the threaded rod 5 is threadedly connected to the fixed tube 4, and one end of the threaded rod 5 close to the nose bridge pressure plate 2 is rotatably connected to the middle part of the moving block 3, and a receiving groove for the moving block 3 and the threaded rod 5 to move is opened in the mask body 1, and when the threaded rod 5 rotates, the moving block 3 reciprocates along the axial direction of the threaded rod 5.
[0027] The working principle and beneficial effects of the above technical solution are: rotating the threaded rod 5 causes the threaded rod 5 and the fixed tube 4 to move relative to each other, and the movement of the threaded rod 5 drives the moving block 3 to move, so that the moving block 3 moves along the axial direction of the threaded rod 5.
[0028] In one embodiment: arc rods 6 are rotatably connected to both sides of the moving block 3, a pair of symmetrically arranged nose wing pressure plates 7 are embedded in the mask body 1, and one end of each arc rod 6 away from the moving block 3 is movably connected to the middle part of the corresponding nose wing pressure plate 7, and a pair of limiting rings 8 are fixedly connected to the mask body 1, and the middle section of each arc rod 6 is sleeved in the corresponding limiting ring 8.
[0029] The working principle and beneficial effects of the above technical solution are as follows: the movement of the moving block 3 drives the arc rods 6 on both sides thereof to move, so that the two arc rods 6 rotate with the corresponding limiting rings 8 as support points, squeezing the corresponding nose wing pressure plates 7, strengthening the supporting effect of the mask body 1 at the nose wings on both sides, and making the force on the entire mask body 1 more uniform.
[0030] In one embodiment: a pair of mounting plates 9 are fixedly connected to the middle of one side surface of each nose wing pressure plate 7, a transverse axis 10 is fixedly connected between the two mounting plates 9, and each arc rod 6 is rotatably connected to the corresponding transverse axis 10.
[0031] The working principle and beneficial effects of the above technical solution are as follows: when the arc rod 6 rotates, it squeezes the horizontal axis 10 and rotates relative to the horizontal axis 10. At the same time, part of the pressure on the nose bridge pressure plate 2 is shared by the two nose wing pressure plates 7 through the two mounting plates 9, so that the entire nose can be evenly stressed when wearing the mask.
[0032] In a specific embodiment: one end of the threaded rod 5 away from the moving block 3 is fixedly connected to a handle 11 , and the handle 11 is provided with anti-slip grooves.
[0033] The working principle and beneficial effects of the above technical solution are as follows: the setting of the handle 11 makes it easier for the user wearing the mask to turn the threaded rod 5, and the anti-slip pattern can increase the friction between the handle 11 and the hand of the staff.
[0034] In one embodiment, the thickness of the nose bridge pressure plate 2 gradually decreases from the middle to both sides.
[0035] The working principle and beneficial effects of the above technical solution are as follows: since the thickness of the nose bridge pressure plate 2 gradually decreases from the middle to the two sides, when the nose bridge pressure plate 2 is pulled, the two sides thereof can be bent with less force due to their thin thickness, and are easier to manipulate.
[0036] In one embodiment, a plurality of connecting rings 12 are fixedly connected to the mask body 1 .
[0037] The working principle and beneficial effects of the above technical solution are as follows: by providing a strap on the connecting ring 12, the mask body 1 can be stably worn on the face.
[0038] In one embodiment, the number of the connecting rings 12 is four.
[0039] The working principle and beneficial effects of the above technical solution are as follows: by inserting straps on the connecting rings 12, the mask body 1 can be stably worn on the face, and two straps can be inserted through the four connecting rings 12 to further improve the stability after wearing.
[0040] Working principle and usage process:
[0041] When it is necessary to adjust the contour of the mask body 1 near the nose bridge according to the actual situation of the wearer, the handle 11 is turned to drive the threaded rod 5 to rotate synchronously, so that the threaded rod 5 and the fixed tube 4 move relative to each other. The movement of the threaded rod 5 drives the moving block 3 to move, so that the moving block 3 moves along the axial direction of the threaded rod 5. When the wearer's nose bridge is more prominent, the handle 11 is turned forward to make the moving block 3 move away from the wearer's face along the axial direction of the threaded rod 5. The moving block 3 drives the nose bridge pressure plate 2 to move synchronously. The two sides of the elastic nose bridge pressure plate 2 are bent by the resistance of the inner wall of the mask body 1. At the same time, the nose bridge pressure plate 2 squeezes the inner wall of the mask body 1, so that the contour of the mask body 1 near the nose bridge changes, thereby reducing the pressure on the nose bridge.
[0042] At the same time, the movement of the moving block 3 drives the movement of the arc-shaped rods 6 on both sides thereof, so that the two arc-shaped rods 6 rotate with the corresponding limiting rings 8 as the supporting points, squeezing the corresponding nose wing pressure plates 7, and strengthening the supporting effect of the mask body 1 at the nose wings on both sides, so that the force on the entire mask body 1 is more uniform. On the contrary, when the wearer's nose bridge is of normal protrusion, the handle 11 is rotated in the opposite direction to move the moving block 3 to the initial position. The wearer can also rotate the handle 11 by himself after wearing it for a long time to adjust the force on the nose bridge according to actual conditions, thereby further improving the practicality of the device.
[0043] The utility model adopts the technical means of cooperating with the moving block 3 and the nose bridge pressure plate 2. The moving block 3 drives the nose bridge pressure plate 2 to move to change the contour of the mask body 1 at the bridge of the nose, thereby reducing the pressure on the bridge of the nose. At the same time, through the movement of two arc-shaped rods 6, part of the pressure at the nose bridge pressure plate 2 is shared to the two nose wing pressure plates 7, thereby overcoming the shortcomings of the existing technology and achieving the technical effect of eliminating safety hazards.
