Abstract
Description
Technical Field
[0001] This utility model relates to the field of anesthesia masks, and more specifically, to anesthesia masks. Background Technology
[0002] An anesthesia mask is a device used to deliver anesthetic gases to patients during surgery or medical procedures. Designing a new anesthesia mask requires consideration not only of its functionality and safety, but also of improving patient comfort, ease of use, convenience, and cleanliness. It also needs to consider the comfort of long-term wear, using breathable materials to reduce dampness and stuffiness, thus enhancing comfort during use. This design combines comfort, functionality, and safety, ensuring that patients maintain a comfortable experience during anesthesia while guaranteeing effective delivery and control of anesthetic gases.
[0003] In practice, when patients are under general anesthesia, the mask is not tightly connected to the patient's face, resulting in poor sealing and easy air leakage, which affects the anesthetic effect. The air in the breathing port contains more bacteria, resulting in poor effectiveness. In addition, the mask needs to be pressed down by hand, which is inconvenient for the operator to use. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and to provide an anesthesia mask that overcomes or at least partially solves the above-mentioned technical problems.

[0007] In a preferred embodiment, the inside of the cover is provided with an installation groove, and the filter screen is disposed inside the installation groove.
[0008] In a preferred embodiment, the surface of the cover is provided with a limit cover, and the surface of the air intake pipe is provided with a limit ring.
[0009] In a preferred embodiment, a connecting ring is provided at the top of the air intake pipe, and a breathing port is provided at the front of the inner cover.
[0010] In a preferred embodiment, mounting holes are provided inside both the outer cover and the inner cover, and the air inlet pipe is disposed inside the mounting holes.
[0011] In a preferred embodiment, grooves are provided on both sides of the inner cover, and the grooves are connected to the air inlet.
[0012] In a preferred embodiment, a limiting groove is formed on the surface of the cover, and a lens is disposed inside the limiting groove.
[0013] In a preferred embodiment, the two sets of adjustment rings are respectively disposed on both sides of the filter screen, and the filter screen is disposed on one side of the breathing port.
[0014] The anesthetic mask provided by this utility model has the following beneficial effects:
[0015] Through the coordinated operation of the silicone frame, inner cover, limiting strap, limiting buckle, adjusting ring, air inlet, limiting cover, cover body, and air inlet tube, the patient's face is first placed inside the silicone frame, and the nose and mouth are placed inside the inner cover. Then, the limiting buckle is used to restrict the patient's head position. The adjusting ring is rotated to close the air inlet, and the limiting cover is engaged with the surface of the cover body, allowing anesthetic gas to be delivered to the inner cover. This ensures a tight connection between the cover body and the patient's face, preventing air leakage and improving the anesthetic effect. A filter is also included to reduce bacteria during patient breathing, further enhancing the device's effectiveness. The adjusting ring, air inlet, tank body, limiting cover, filter, and limiting cover allow for gas intake. Once the gas enters, it flows into the tank body, allowing for control of the amount of anesthetic gas entering. After anesthesia, the limiting cover can be removed, allowing the patient to breathe normally. When the filter needs replacement, the limiting cover can be removed directly for easy replacement.

[0021] Example: As attached Figures 1 to 4 As shown, an anesthesia mask includes a limiting strap 2, with limiting buckles 21 on both sides of the limiting strap 2. A mask body 11 is located on one side of the limiting buckle 21. A filter screen 25 is installed inside the mask body 11. A silicone frame 19 is located on one side of the mask body 11. An inner cover 17 is installed inside the silicone frame 19. An air inlet pipe 16 is inserted between the inner cover 17 and the mask body 11. Air inlets 15 are located on both sides of the mask body 11. An adjusting ring 12 is located on one side of each of the two sets of air inlets 15. Through the cooperation of the silicone frame 19, inner cover 17, limiting strap 2, limiting buckle 21, adjusting ring 12, air inlets 15, limiting cover 22, mask body 11, and air inlet pipe 16, when the operator needs to use it, the patient's face can first be inserted into the silicone frame 19. Inside, the nose and mouth are inserted into the inner cover 17. After insertion, the operator can extend the limiting strap 2 and then use the limiting buckle 21 to limit the patient's head. After limiting, the operator can rotate the adjusting ring 12 to close the air inlet 15. After closing, the operator can insert the limiting cover 22 into the surface of the cover 11. After completion, the operator can connect the air inlet pipe 16 to the anesthetic gas pipeline. After connection, the operator can deliver anesthetic gas to the inner cover 17, so that the cover 11 can be tightly connected to the patient's face without leakage, improving the anesthetic effect. In addition, by setting the filter screen 25, bacteria can be reduced when the patient breathes, improving the effectiveness of the device.
[0022] Reference Figures 1-4In a preferred embodiment, the inside of the cover 11 is provided with a mounting groove 24, which allows the filter 25 to be placed. The filter 25 is disposed inside the mounting groove 24. A limit cover 22 is provided on the surface of the cover 11, which allows the patient's breathing port 26 to be limited or opened. A limit ring 14 is provided on the surface of the air inlet pipe 16, and a connecting ring 13 is provided at the top of the air inlet pipe 16. The front of the inner cover 17 is provided with a breathing port 26. Mounting holes are provided inside both the cover 11 and the inner cover 17. The air inlet pipe 16 is disposed inside the mounting holes. An adjusting ring 12 is used to adjust the air inlet pipe 26. The system includes an air inlet 15, a tank 18, a limiting cover 22, and a filter 25. The limiting cover 22 allows the operator to control the flow rate of anesthetic gas by rotating the adjusting ring 12 to allow gas to enter through the air inlet 15. The gas then enters the tank 18, thus controlling the amount of anesthetic gas entering. After the patient is anesthetized, the operator can remove the limiting cover 22 to allow the patient to breathe normally. The filter 25 can also be replaced by simply removing the limiting cover 22, making it convenient for the operator.
[0023] Reference Figures 1-4 In a preferred embodiment, grooves 18 are provided on both sides of the inner cover 17, and the grooves 18 are connected to the air inlet 15. A limiting groove is provided on the surface of the cover 11, and a lens 23 is provided inside the limiting groove. By providing the lens 23, the patient can look out and will not be in darkness, reducing the patient's fear. Two sets of adjustment rings 12 are respectively provided on both sides of the filter screen 25, and the filter screen 25 is provided on one side of the breathing port 26. Through the above arrangement, bacteria can be reduced when the patient breathes, thus improving the effectiveness of the device.
[0024] Specifically, the working process or principle of this anesthesia mask is as follows: In the actual use of anesthesia masks, during general anesthesia, the mask is often not tightly connected to the patient's face, resulting in poor sealing and easy air leakage, affecting the anesthetic effect. The air inlet 26 also tends to harbor more bacteria, leading to poor effectiveness. Furthermore, the mask requires manual pressure, making it inconvenient for the operator. Therefore, this technical solution solves these problems. When the operator needs to use it, first, the patient's face is inserted into the silicone frame 19, and the nose and mouth are inserted into the inner cover 17. After insertion, the operator can extend the limiting strap 2. Then, based on the patient's head, the operator can use the limiting buckle 21 to limit the patient's head position. After limiting, the operator can rotate the adjusting ring 12 to close the air inlet 15. After closing, the operator can insert the limiting cover 22 onto the surface of the mask body 11. Finally, the operator... The air inlet pipe 16 can be connected to the anesthetic gas pipeline. After connection, the operator can deliver the anesthetic gas to the inner mask 17, so that the mask 11 can be tightly connected to the patient's face without leakage, improving the anesthetic effect. In addition, by setting the filter screen 25, bacteria can be reduced when the patient breathes, improving the effectiveness of the device. When the operator needs to control the flow rate of the anesthetic gas, the operator can rotate the adjusting ring 12 to allow the gas to enter through the air inlet 15. After the gas enters, it can enter the interior of the tank 18, thereby controlling the amount of anesthetic gas entering. After the patient is anesthetized, the operator can remove the limiting cover 22, allowing the patient to breathe normally. When the operator needs to replace the filter screen 25, the operator can also directly remove the limiting cover 22 to replace the filter screen 25 for convenient operation. The entire process is now complete.
