[0002] During surgery, anesthesia is necessary beforehand. Traditional anesthesia involves injecting anesthetic drugs into the patient's body to achieve the desired effect. However, with the continuous development of medical equipment, anesthesia is now typically performed using safer and more convenient anesthesia machines. An anesthesia machine is used to deliver anesthetic drugs to the patient and also includes a breathing circuit to assist the patient's respiration under anesthesia. When the human body breathes, it produces carbon dioxide. If the carbon dioxide produced by the patient's respiration is not effectively processed in the anesthesia machine's breathing circuit, the patient will be unable to breathe normally and will experience discomfort. To absorb the carbon dioxide produced by the patient, a carbon dioxide breathing tank is installed in the breathing circuit.

[0003] Carbon dioxide breathing canisters are an important component of anesthesia machines, used to absorb carbon dioxide produced during the patient's respiration, preventing excessive carbon dioxide in the breathing circuit, which can lead to breathing difficulties and physical discomfort. However, existing carbon dioxide breathing canisters are prone to insufficient absorption of exhaled carbon dioxide, resulting in leakage. Furthermore, their complex structure makes replacement inconvenient and cumbersome when the absorbent loses its effectiveness. Utility Model Content

A main cover 21 is located above the main canister 11 and has a protrusion 22 structure. An air inlet 23 and an air outlet 24 are respectively provided at both ends of the protrusion 22. This design facilitates the entry and exit of gas, ensuring smooth airflow inside the breathing canister. To further enhance structural stability, grooves 13 are provided on both sides of the main canister 11. A fixing component is provided within the groove 13 to fix the position of the main cover 21, preventing it from loosening or moving. Additionally, fixing blocks 25 are provided on both sides of the main cover 21. A locking block 26 is provided on the bottom surface of the fixing block 25, which can be locked within the fixing component to ensure a secure connection between the main cover 21 and the fixing component. This carbon dioxide breathing canister features a compact design with all components working in tandem to ensure stability and proper functioning. It not only facilitates the entry and exit of gas but also effectively absorbs carbon dioxide, providing safe and reliable respiratory support for patients. A sealing ring 15 is installed between the main canister 11 and the main cover 21 to ensure the canister's airtightness. The sealing ring 15 is typically made of highly elastic rubber, offering excellent sealing and corrosion resistance, preventing carbon dioxide leakage and ensuring a stable gas environment inside the canister. Furthermore, the sealing ring 15 prevents external air and dust from entering the canister, protecting the internal gas from external contamination.

[0026] like Figure 2 , 3As shown in Figure 5, the absorption assembly is an important part of the carbon dioxide breathing canister. It includes an absorption canister 31, an absorption cover 32, and a gas guide tube 33. The absorption canister 31 is the core part of the absorption assembly; it is secured within the placement groove 12 to ensure its stability. The absorption cover 32 is positioned above the absorption canister 31, and the absorption cover 32 is threadedly connected to the absorption canister 31 to form an absorption space. An absorbent can be placed within this absorption space to absorb carbon dioxide. To facilitate gas entry and exit, a connecting through-hole 34 is provided on the absorption cover 32. One end of the gas guide tube 33 is secured within the connecting through-hole 34, and the other end is secured within the air inlet 23. This design aims to guide the mixed gas entering the breathing canister through the absorbent to achieve carbon dioxide absorption. An outlet tube 35 is also provided on the absorption cover 32 to discharge the absorbed gas. To enhance the stability of the absorption assembly, connecting blocks 36 are provided at both ends of the absorption cover 32. The placement slot 12 has a matching annular groove 14 corresponding to the connecting block 36. The connecting block 36 can be locked in the annular groove 14 to ensure a firm connection between the absorption cover 32 and the placement slot 12. At the same time, the absorption cover 32 is also provided with a lifting block 37 to facilitate the removal of the absorption can 31 from the main can 11.

[0027] like Figure 2 , 4 As shown, the fixing base 41 is the basic part of the fixing component. It is locked in the groove 13 to ensure its stability. The fixing base 41 has a through groove 42, and the locking block 26 is locked in the through groove 42. A fixing groove 43 is also opened on one side of the fixing base 41. The fixing groove 43 has a fixing recess 44, and the fixing recess 44 contains a spring 45. This design can provide a certain degree of elasticity, so that the fixing component has a certain cushioning effect. The locking seat 46 is another key part of the fixing component. It is locked in the fixing groove 43 and connected to the spring 45 in the fixing recess 44. The locking seat 46 plays a role in fixing the locking block 26. A pressing block 47 is provided on one side of the card holder 46. The pressing block 47 can control the pressure on the spring 45 to fix the card holder 46 to the card block 26. When the card block 26 is directly inserted into the through groove 42 and contacts the card holder 46, the elasticity of the spring 45 fixes the card holder 46 to the card block 26. Pressing the pressing block 47 compresses the spring 45, releasing the card holder 46 from fixing the card block 26, facilitating the installation and removal between the main body can 11 and the main body cover 21. A baffle 48 is also provided on one side of the fixed base 41, and a through hole 49 is opened on the baffle 48 corresponding to the pressing block 47. The baffle 48 is connected to the fixed base 41, and the pressing block 47 passes through the through hole 49. This design can prevent the card holder 46 from loosening or falling off, ensuring the stability of the fixing component.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When using this carbon dioxide breathing canister, first, place the absorption assembly in the placement slot 12 of the main canister 11, ensuring the absorption canister 31 is stably positioned. Then, place the main cover 21 on top of the main canister 11, ensuring the air inlet 23 of the main cover 21 is connected to the air guide tube 33 on the absorption assembly. A sealing ring 15 is installed on the contact surface between the main canister 11 and the main cover 21. Ensure the sealing ring 15 is fully embedded in the sealing groove to guarantee the breathing canister's sealing performance. Align the locking block 26 of the main cover 21 with the through slot 42 on the fixing base 41 on the main canister 11, and fix the locking block 26 using the locking base 46, thus connecting the main canister 11 and the main cover 21 as a single unit.

[0030] During use, when the breathing canister needs to absorb carbon dioxide, air enters the canister through the air inlet 23 of the main cover 21. After entering the canister, the air passes through the absorbent in the absorption assembly, absorbing the carbon dioxide. Then, the absorbed gas is discharged into the breathing canister through the outlet pipe 24 of the absorption cover 32, and then discharged through the outlet 24 on the main cover 21. The presence of the sealing ring 15 ensures that the gas environment inside the breathing canister remains stable and prevents gas leakage and the entry of external contaminants.

[0031] This carbon dioxide breathing canister provides safe and reliable breathing support. It absorbs carbon dioxide through an absorption component, providing fresh air for the user to breathe, maintaining a stable gaseous environment inside the canister, and preventing gas leaks and the entry of external contaminants. The design of the fixing components ensures stable installation of the absorption component and the main cover 21. Furthermore, installation and disassembly are convenient, facilitating the replacement of the absorbent in the breathing canister.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
