[0019] Figure 1 This is a front view of the curved anesthesia mask provided according to an embodiment of the present invention; Figure 2 This is a left view of the curved anesthesia mask provided according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the curved anesthesia mask provided according to an embodiment of the present invention; Figure 4 This is an isometric view of a curved anesthesia mask provided according to an embodiment of the present invention.

[0020] The following is for reference. Figures 1-4 A curved anesthesia mask 10 according to an embodiment of the present invention is described, comprising: a mask body 100, one side of which has an open receiving cavity 110; a curved airbag 200, which is disposed around the open position of the receiving cavity 110 and is adapted to fit closely to the patient's face; and a suction port 300, which is disposed on the other side of the mask body 100 away from the receiving cavity 110 and communicates with the receiving cavity 110, and is adapted to communicate with an external device.

[0021] Specifically, the mask 100 can be constructed as a semi-circular shape with an opening on one side. The material of the mask 100 can be engineering plastics, such as high-transparency polycarbonate. Polycarbonate has higher strength and heat resistance, and is corrosion-resistant. In actual production, users can choose different materials for the mask 100 according to different application scenarios. The mask 100 is one of the main components of the anesthesia mask 10. The mask 100 helps the user stably place the anesthesia mask 10 on the patient's face, improving the efficiency of anesthesia procedures and providing the patient with more adequate and high-quality respiratory support, thereby protecting the patient's respiratory system.

[0022] Furthermore, the curved airbag 200 can be constructed as a hollow cylindrical structure. The curved airbag 200 can be installed around the opening of the cover 100, and the connection method can be bonding, welding, or integral molding. The patient's nose contact point of the curved airbag 200 is not on the same plane as the patient's face contact point; the patient's nose contact point is slightly higher than the patient's face contact point. This design allows the curved airbag 200 to better conform to the patient's nasal structure, thereby dispersing nasal pressure, reducing the incidence of nasal pressure injuries, and thus increasing patient comfort.

[0023] The curved airbag 200 can be configured as an inflatable structure. During use, the user inflates the curved airbag 200 via a one-way valve 400. When inflated, the curved airbag 200 reduces direct friction and pressure between the anesthesia mask 10 and the patient's skin, minimizing discomfort or pressure sores caused by concentrated pressure. Simultaneously, the curved airbag 200 creates a sealed area between the anesthesia mask 10 and the patient's face, preventing anesthetic gas leakage and ensuring effective delivery of the anesthetic gas.

[0024] The suction port 300 can be constructed as a cylindrical through-hole with an internal active valve 310. The suction port 300 can be located on the surface of the mask 100 opposite to the receiving cavity 110 and the contact point with the patient's nose, and is connected to the receiving cavity 110. The suction port 300 can be fixedly connected to the mask 100 by welding or integral molding. The end of the suction port 300 opposite to the mask 100 can be connected to an external device (not shown in the figure), which can be a suction catheter. The suction port 300 can be connected to and communicate with the suction catheter, allowing the user to perform emergency suctioning to prevent patient suffocation and ensure the patient's respiratory safety. The suction port 300 avoids the need to remove the entire anesthesia mask 10 each time suctioning is performed and then re-wear the anesthesia mask 10 after suctioning, allowing the user to quickly complete the suctioning operation.

[0025] The active valve 310 can be constructed as a cross-shaped ring structure. The active valve 310 can be fixedly installed inside the suction port 300 by means of bonding, welding, or integral molding. The suction catheter can be inserted into the anesthesia mask 10 through the cross-shaped structure of the active valve 310, enabling emergency suctioning of the patient. The active valve 310 ensures that the receiving cavity 110 of the anesthesia mask 10 is a sealed space, preventing gas from flowing out through the active valve 310; the suction catheter can only be inserted from the outside, thus improving the practicality and safety of the anesthesia mask 10.

[0026] According to an embodiment of this utility model, a curved anesthesia mask 10 is provided. The mask body 100 helps the user stably wear the mask 10 on the patient's face, improving the efficiency of the anesthesia procedure and providing the patient with more adequate and high-quality respiratory support, thus protecting the patient's respiratory system. The curved airbag 200 better conforms to the patient's nasal structure, dispersing nasal pressure and reducing the incidence of nasal pressure injuries, thereby increasing patient comfort. The curved airbag 200 forms a sealed area between the anesthesia mask 10 and the patient's face, preventing anesthetic gas leakage and ensuring effective gas delivery. The suction port 300 allows the user to perform emergency suctioning to prevent suffocation and ensure respiratory safety. The suction port 300 avoids the need to remove the entire anesthesia mask 10 for each suctioning procedure and re-wear it afterward, allowing the user to quickly complete the suctioning operation.

[0027] Please continue to participate. Figures 1-3 As shown, the curved surface anesthesia mask 10 also includes a one-way valve 400, which is disposed on the surface of the curved airbag 200 and communicates with the curved airbag 200. The one-way valve 400 is adapted to inflate the curved airbag 200.

[0028] It should be noted that the one-way valve 400 can be fixedly connected and communicated with the curved airbag 200 by means of bonding, welding or other methods. The one-way valve 400 can be set on the surface of the curved airbag 200 and perpendicular to the curved airbag 200. This can ensure that the one-way valve 400 can deliver gas into the curved airbag 200, and the one-way valve 400 will not cause damage to the patient's face when the patient wears the anesthesia mask 10, thereby improving the safety of the anesthesia mask 10.

[0029] Furthermore, the one-way valve 400 can inject gas into the curved airbag 200 through a syringe without a needle (not shown in the figure). The one-way valve 400 can prevent gas backflow. With this setting, the curved airbag 200 can remain in an inflated state after inflation, thereby improving the safety and comfort of the anesthesia mask 10.

[0030] Please continue reading Figures 1-4 As shown, according to one embodiment of the present invention, the curved anesthesia mask 10 further includes an air supply hole 500, which is disposed on the surface of the mask body 100 and communicates with the receiving cavity 110. The air supply hole 500 is adapted to deliver anesthetic gas into the mask body 100.

[0031] Specifically, the air supply port 500 can be constructed as a cylindrical structure. The air supply port 500 can be fixedly installed on the surface of the cover 100 by welding or integral molding, and communicates with the receiving cavity 110. The air supply port 500 can be connected to the anesthesia machine (not shown in the figure) through an anesthesia tubing (not shown in the figure), thereby providing an effective non-invasive breathing circuit for the patient.

[0032] Please continue reading Figures 1-4 As shown, according to another embodiment of the present invention, the suction port 300 further includes a buckle 320, which is movably connected to the suction port 300 and is adapted to fit into the suction port 300 to keep the anesthesia mask 10 sealed and prevent leakage of anesthetic gas.

[0033] Specifically, the buckle 320 can be configured as a circular planar structure. The buckle 320 can be movably connected to the suction port 300 via the connector 330. The buckle 320 and the suction port 300 can fit together to form a sealed space in the receiving cavity 110 of the anesthesia mask 10, preventing the escape of anesthetic gas from the mask body 100. The buckle 320 can be constructed from a polymer material, such as polyimide. Polyimide has good pressure resistance, can withstand high temperatures and pressures, and is resistant to corrosion from acids, alkalis, and chemicals, exhibiting good stability. This embodiment of the invention does not impose specific limitations on this aspect; users can choose different buckle 320 materials according to different application scenarios.

[0034] Please continue reading Figure 1 and Figure 4 As shown, according to another embodiment of the present invention, the suction port 300 further includes: a connector 330, one end of the connector 330 is fixedly connected to the suction port 300, and the other end of the connector 330 is fixedly connected to the buckle 320. The connector 330 is adapted to be movably connected between the buckle 320 and the suction port 300.

[0035] Specifically, the connector 330 can be constructed as a rectangular strip structure, and the construction material of the connector 330 can be the same as that of the buckle 320. This embodiment of the invention does not impose specific limitations on this aspect. One end of the connector 330 can be fixedly connected to the outer surface of the suction port 300 by means of bonding, welding, or other connection methods. The other end of the connector 330 can be fixedly connected to the top of the buckle 320 by means of bonding, welding, or other connection methods. This design prevents the buckle 320 from being lost and allows for quick and convenient operation when using the suction port 300, thereby improving the practicality of the anesthesia mask 10.

[0036] Please continue reading Figures 1-4As shown, according to an optional embodiment of the present invention, the curved anesthesia mask 10 further includes an anti-slip pad 600, which is disposed on the surface of the mask body 100 and facilitates the user's gripping of the anesthesia mask 10.

[0037] Specifically, the anti-slip mat 600 can be configured as a strip-shaped structure with raised stripes on its surface. The anti-slip mat 600 can be attached to the surface of the mask body 100 away from the receiving cavity 110 by means of bonding, welding, or other connection methods. This makes it easier for users to grasp the mask from various angles without slipping, thus improving the practicality of the anesthesia mask 10.
