[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] like Figures 1 to 5 As shown, the present invention provides an adaptive sealing atomizing face mask, comprising:

[0034] The mask frame 1 is a one-piece molded structure, and the mask frame 1 includes a head fitting area, a cheek fitting area and a chin fitting area.

[0035] The mouth and nose mask 2 is fixedly installed on the mask frame 1, and the mouth and nose mask 2 is provided with an air inlet;

[0036] The oral and nasal sealing pad 3 is fixedly installed on the oral and nasal mask 2 and is used to fit the patient's mouth and nose. The oral and nasal sealing pad 3 is provided with a nose fitting area and a mouth fitting area.

[0037] Facial sealing pad 4 is fixedly attached to the contour of the mask frame 1 and is used to fit the patient's face.

[0038] The strap assembly 5 is disposed on the mask frame 1 and is used to fix the entire mask to the patient's face;

[0039] The working process and principle of the device are as follows: The patient loosens the strap assembly 5 of the adaptive sealing nebulizer mask, aligns the mask frame 1 with the face, and basically aligns the head, cheek, and chin fitting areas with the corresponding parts of the patient; adjusts the tightness of the strap assembly 5 to secure the mask tightly to the patient's face, ensuring that the mask will not loosen or fall off; the nasal and oral sealing pad 3 fits tightly against the patient's mouth and nose, with its nose and mouth fitting areas matching the shape of the patient's nose and mouth respectively, forming an effective seal; the facial sealing pad 4 adheres to the contour of the mask frame 1, fitting tightly against the patient's facial contour, further enhancing the mask's seal and preventing fogging; the nebulizer delivers the nebulized medication into the mask through the air inlet on the nasal and oral mask 2; the patient breathes through the mouth and nose, inhaling the nebulized medication for treatment; the mask frame 1 adopts a one-piece molded structure, enhancing the overall stability and durability of the mask; the frame is designed with... The head, cheek, and chin fitting areas allow the mask to better adapt to the facial contours of different patients, improving wearing comfort and sealing. The nasal mask 2 is fixedly mounted on the mask frame, with its air inlet for connecting to the nebulizer and delivering nebulized medication. The nasal sealing pad 3 is made of a soft and elastic material, tightly conforming to the patient's mouth and nose to form an effective seal, preventing mist leakage and improving medication utilization. The facial sealing pad 4 is fixed to the contour of the mask frame, using a material compatible with facial skin to ensure comfort during extended wear. The shape and material of the sealing pad allow it to closely conform to the patient's facial contours, further enhancing the mask's sealing performance. The strap assembly 5 is located on the mask frame to secure the entire mask to the patient's face. Through a tight fit and effective sealing, the nebulized medication is accurately delivered to the patient's respiratory tract, improving treatment efficacy.

[0040] It also includes an air intake filter plate 6, which is fixedly installed in the air intake of the nasal mask 2 to filter large particulate impurities. The air intake filter plate 6 is fixedly installed in the air intake of the nasal mask 2. When the nebulizer is activated, the generated drug mist enters the nasal mask 2 through the air intake. Before entering the nasal mask, the mist first passes through the air intake filter plate 6. The filter material on the air intake filter plate 6 captures and blocks large particulate impurities in the mist, such as dust and fibers. The mist filtered by the air intake filter plate 6 becomes cleaner, removing large particulate impurities that could irritate or infect the patient's respiratory tract. The clean mist then enters the patient's respiratory tract through the nasal mask 2 and the nasal sealing pad 3 for nebulization therapy. When passing through the air intake filter plate 6, large particles of impurities, due to their large size, cannot penetrate the fine pores of the filter plate and are therefore blocked on the surface of the filter plate. Meanwhile, the drug mist, due to its small size, can easily pass through the filter plate and enter the mouth and nose mask. The presence of the air intake filter plate 6 effectively prevents large particles of impurities that may be generated during nebulization from entering the patient's respiratory tract. This not only improves the safety of nebulization therapy but also reduces the risk of respiratory irritation or infection that may be caused by inhaling impurities. The air intake filter plate 6, through a physical filtration mechanism, effectively blocks large particles of impurities in the mist, ensuring that the mist entering the patient's respiratory tract is cleaner and safer. This not only improves the effectiveness of nebulization therapy but also further protects the patient's respiratory health.

[0041] It also includes a quick-connect connector 7, which is connected to the input end of the air inlet of the nasal mask 2 for quick connection with the external tubing. The quick-connect connector 7 is designed and installed at the input end of the air inlet of the nasal mask 2, serving as the connection interface between the nebulizing mask and an external nebulizing device or gas supply pipe. Before use, ensure that the quick-connect connector 7 is disconnected and that its internal channels are clean and unobstructed. When connecting the nebulizing mask to the external tubing, align the connector portion of the external tubing with the quick-connect connector 7; gently push in the connector of the external tubing, and the external tubing and the air inlet of the nasal mask 2 achieve an airtight connection through the quick-connect connector 7. After connection, the drug mist or gas generated by the nebulizing device flows through the external tubing. The quick-connect connector 7 enters the air inlet of the nasal mask 2; the mist then passes through the air intake filter plate 6 to remove large particles before entering the nasal mask for the patient to inhale; after treatment, or when the mask needs to be replaced or cleaned, the connection can be quickly disconnected; the quick-connect and disconnect features of the quick-connect connector 7 make the maintenance and replacement of the mask more convenient; medical staff can quickly disconnect the outer tube and clean or replace mask components without spending a lot of time on complex connection and disassembly processes; the quick-connect connector 7 achieves a quick, secure, and safe connection between the outer tube and the nasal mask; it not only improves the efficiency and convenience of nebulization treatment, but also enhances the versatility and maintainability of the mask.

[0042] It also includes one-way exhaust valves 8. Two one-way exhaust valves 8 are symmetrically connected to both sides of the nasal mask 2 for expelling respiratory waste gas. The one-way exhaust valves 8 are symmetrically arranged on both sides of the nasal mask 2 and communicate with the internal space of the nasal mask. When the patient wears the adaptive sealing nebulizer mask for breathing, the inhaled drug mist enters the nasal mask through the air inlet for the patient to inhale. During exhalation, the waste gas exhaled by the patient needs to be expelled to avoid accumulation in the nasal mask. During exhalation, due to the increase in pressure inside the nasal mask, the valve of the one-way exhaust valve is pushed open, and the waste gas is expelled. During inhalation, the pressure inside the nasal mask decreases, and the valve of the one-way exhaust valve automatically closes to prevent external air or pollutants from entering the nasal mask. The valve structure of the one-way exhaust valve also has a certain pressure regulation function. During exhalation, the mask automatically opens when the pressure inside reaches a certain level, allowing waste gas to escape. During inhalation, the mask closes tightly due to the reduced pressure, ensuring no external air or contaminants enter. The one-way exhaust valve effectively reduces waste gas buildup inside the mask, improving patient comfort. It also ensures effective use of the medication mist, as waste gas is promptly expelled without interfering with the inhalation of the new medication mist. This reduces stuffiness and discomfort inside the mask. The one-way exhaust valve 8, through its one-way flow and pressure regulation function, ensures that exhaled waste gas is smoothly expelled to the external environment while preventing external contaminants from entering the mask. This not only improves patient comfort and treatment effectiveness but also enhances the mask's safety and reliability.

[0043] It also includes two filter mechanisms 9 and a protective cover 93. The protective cover 93 is fixedly connected to the mask frame 1 and covers the mouth and nose mask 2. Both filter mechanisms 9 are mounted on the protective cover 93, and each filter mechanism 9 is connected to one-way exhaust valves 8. The protective cover 93 is fixedly connected to the mask frame 1 and fits tightly on the mouth and nose mask 2, providing a stable mounting platform for the filter mechanisms 9. The two filter mechanisms 9 are mounted on the protective cover 93, and their positions correspond to the two one-way exhaust valves 8, ensuring that each exhaust valve has a corresponding one-way exhaust valve. The system includes a connected filtration mechanism. When a patient wears an adaptive sealing nebulizer mask, the inhaled medication mist enters the nasal mask through the air inlet for the patient to inhale. During exhalation, the patient's exhaled waste gas is discharged through a one-way exhaust valve 8. At this time, the filtration mechanism 9 plays a crucial role, filtering the discharged waste gas to remove contaminants such as bacteria, viruses, and particulate matter. After flowing out of the one-way exhaust valve 8, the waste gas first enters the connected filtration mechanism 9. The filter material inside the filtration mechanism 9 filters the waste gas, and the purified gas is then discharged. External environment; the protective cover 93 not only provides installation space for the filter mechanism 9, but also plays a certain role in shielding, preventing external pollutants from directly contacting the nasal mask 2 and the filter mechanism 9; it enhances the overall protective performance of the mask, especially in epidemic or polluted environments, and can effectively reduce the risk of patients inhaling harmful substances; the filter mechanism 9 is a key component of the mask, which uses the adsorption, interception, electrostatic effect and other mechanisms of the filter material to purify the exhaled exhaust gas; the presence of the filter mechanism 9 and the protective cover 93 effectively reduces the pollutants in the patient's exhaled exhaust gas, reducing the risk of cross-infection; at the same time, it also enhances the sealing and protective performance of the mask, improving the patient's comfort and treatment effect; for patients who need to wear the mask for a long time for respiratory therapy, it reduces the risk of patients inhaling harmful substances, and improves the safety and effectiveness of treatment; the filter mechanism 9 and the protective cover 93, through filtration and shielding, ensure that the exhaled exhaust gas is purified, while preventing external pollutants from entering the mask; it not only improves the protective performance and sealing of the mask, but also enhances the patient's comfort and treatment effect.

[0044] The filter unit 9 also includes:

[0045] The filter box 91 is fixedly connected to the protective cover 93. The filter box 91 has a cavity inside. The filter box 91 is connected to the one-way exhaust valve 8 through a pipe. The filter box 91 is provided with an air outlet.

[0046] The protective filter plate 92 is fixedly installed inside the filter box 91 and is used to filter the gas.

[0047] When a patient exhales while wearing an adaptive sealing nebulizer mask, the exhaled waste gas enters the internal cavity of the filter box 91, which is connected to it, through a one-way exhaust valve 8. The waste gas entering the filter box 91 first comes into contact with the protective filter plate 92. The protective filter plate 92 is made of materials with filtering functions, such as activated carbon and high-efficiency filter membranes, which can adsorb and intercept pollutants such as bacteria, viruses, and particulate matter in the waste gas. The gas after being filtered by the protective filter plate 92 becomes relatively clean and is then discharged into the external environment through the air outlet on the filter box 91. The presence of the filtration mechanism 9 effectively reduces the pollutants in the patient's exhaled waste gas, reduces the risk of cross-infection, and improves the effect of nebulizer therapy.

[0048] The band assembly 5 also includes:

[0049] Four fixing straps 51 are separately and fixedly installed on the mask frame 1;

[0050] Four adjusting rings 52 are respectively oscillating and set on four fixed belts 51;

[0051] Two main belts 53 are adjusted and set in four adjusting rings 52 respectively;

[0052] The fixing straps 51 are distributed and fixedly installed on the mask frame 1, located around the mask. The function of the fixing straps 51 is to provide stable support points for the adjustment rings 52 and the main straps 53. The adjustment rings 52 are respectively swayed on the four fixing straps 51 and can slide or rotate on the fixing straps to adjust their position. The adjustment rings 52 allow the patient to flexibly adjust the tightness and position of the straps according to their individual face shape and needs. The main straps 53 are respectively adjusted and set in the four adjustment rings 52, and are connected by passing through the adjustment rings and knotting. The main straps 53 are used to fix the mask to the patient's head, tightening the mask and keeping it in the correct position. The patient first places the mask frame 1 on their face, ensuring that the mouth and nose mask 2 and the facial sealing pad 4 fit tightly against the face. The patient adjusts the mask position by pulling or loosening the main straps 53. The fit of the entire mask on the face; the swing design of the adjustment ring 52 allows the patient to easily find the most suitable band tightness during adjustment; once the band tightness is adjusted to the appropriate position, the patient secures the main band 53 to the head, ensuring the mask remains stable during respiratory therapy; the swing design of the adjustment ring 52 and the adjustability of the main band 53 allow the band assembly 5 to adapt to different patients' face shapes and needs; ensuring the mask fits closely to various face shapes, improving sealing and comfort; four fixing straps 51 are distributed on the mask frame 1, providing stable support for the band assembly, ensuring the mask will not loosen or fall off during respiratory therapy; the band assembly 5 not only improves the mask's sealing and stability but also enhances patient comfort.

[0053] It also includes horizontal straps 54. At least three horizontal straps 54 are fixedly installed between the two main straps 53. The horizontal straps 54 are elastic. After the patient adjusts the tightness and position of the main straps 53, the horizontal straps 54 will fit tightly against the back of the patient's head due to their elasticity, forming a stable support point. This support point helps prevent the mask from loosening or falling off during respiratory therapy due to the patient's head movement or breathing movements. The elasticity of the horizontal straps 54 allows them to maintain a certain tightness during prolonged wear, neither too tight to cause discomfort to the patient nor too loose to cause the mask to loosen. This helps reduce the pressure and burden on the patient when wearing the mask, improving the patient's comfort and willingness to wear it. When the horizontal straps 54 are stretched, they store elastic potential energy. When the external force decreases, they release this potential energy and return to their original shape and length. This elastic support allows the horizontal straps to automatically adapt to the head circumference and head size when the patient wears the mask. The face shape provides stable support for the mask; the design of the horizontal strap 54 helps to distribute the pressure of the mask on the patient's head; due to the elasticity of the horizontal strap, it can absorb and distribute the local pressure of the mask on the patient's head to a certain extent, making it more comfortable to wear; the horizontal strap 54, together with the main strap 53 and the fixing strap 51, forms a stable fixation system; it can ensure that the mask remains stable during respiratory therapy and will not loosen or fall off due to the patient's head movement or breathing movements; the elastic support and stabilizing effect of the horizontal strap 54 helps to ensure that the mask remains stable during prolonged wear, improving the reliability and effectiveness of wearing; the elastic design and pressure distribution effect of the horizontal strap 54 help to reduce the pressure and burden on the patient when wearing the mask, improving the patient's comfort and willingness to wear it; stable wearing and comfortable experience help patients better cooperate with respiratory therapy, improving the effective utilization rate of drugs and treatment effects.
