[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1: Refer to Figure 1-6A respirator includes a housing 1. A first supply device 2 and a second supply device 3 are fixedly installed inside the housing 1. The first supply device 2 and the second supply device 3 are used to supply oxygen and anesthetic gas, respectively, both being existing technologies. The first supply device 2 and the second supply device 3 are connected to an adapter 4 via a first tube. Two first tubes are provided, and the two supply devices respectively deliver gas into the adapter 4 through the first tubes. A second tube is provided and connected to the adapter 4. The adapter 4 delivers the gas supplied from the first tube into the second tube, thus allowing the oxygen and anesthetic gas to mix inside the second tube.
[0022] The adapter 4 is connected to a matching conduit 8 via a second tube. Gas is delivered from the adapter 4 into the conduit 8 through the second tube. A mask 9 is connected to the end of the conduit 8, which delivers the mixed gas into the mask 9, providing anesthesia to the patient. Both the conduit 8 and the mask 9 are existing devices, which can be disposable or reusable, and both can be sterilized by the sterilization device 12. The conduit 8 and the end of the second tube are easily detached and reassembled, facilitating easy replacement of the conduit 8 and the mask 9.
[0023] A mixing mechanism is fixedly installed inside the second tube, which further ensures the uniform mixing of oxygen and anesthetic gas. A protective shell 10 is fixedly installed on one side of the outer casing 1, with a hinged door on the side for easy opening and closing. A disinfection device 12 is fixedly installed inside the protective shell 10. The disinfection device 12 can be an ultraviolet disinfection lamp, which has a disinfection and sterilization function. However, the door of the disinfection device 12 must not be opened during operation to prevent harm to the user. The disinfection device 12 can be located on the top or side of the protective shell 10, depending on specific needs. A bracket 11 is fixedly installed on the inner wall of one side of the protective shell 10. The bracket 11 is a circular column with a notch on the side. The matching conduit 8 is fitted inside this circular column and secured by the bracket 11, allowing the mask 9 to be temporarily stored and stabilized inside the protective shell 10. The disinfection device 12 can disinfect and sterilize the mask 9 and the matching conduit 8. This not only prevents the mask 9 and the matching conduit 8 from external contamination through the protective shell 10 but also allows for timely disinfection, improving the safety of the mask 9 during use. Furthermore, the disinfection equipment 12 can simultaneously disinfect the inside of the protective shell 10 and the end of the second tube, preventing the machine from being contaminated.
[0024] A drying mechanism is threaded into the bottom of the protective shell 10. This mechanism dries the interior of the protective shell 10. The drying mechanism includes a filling box 13, the outer surface of which is threaded to the bottom of the protective shell 10. The filling box 13 is easily removable and replaceable. A mesh plate 14 is fixedly installed inside the upper part of the filling box 13. The mesh plate 14 provides protection, preventing debris from falling into the filling box 13. An activated carbon plate 15 and drying granules 16 are fixedly arranged inside the filling box 13. The activated carbon plate 15 has a spiral cross-section, and the drying granules 16 fill the gaps within it. The activated carbon plate 15 effectively purifies the air, absorbing odors and some harmful gases, while the drying granules 16 absorb moisture from the air. Together, the activated carbon plate 15 and the drying granules 16 keep the interior of the protective shell 10 dry, preventing bacterial growth and reducing the burden on the disinfection equipment.
[0025] Working principle: During use, the first supply device 2 and the second supply device 3 deliver oxygen and anesthetic gas to the second tube through the adapter 4. The second tube then delivers the mixed gas to the mask 9 through the matching tubing 8. The mask 9 is used to anesthetize the patient. When the mask 9 is removed from the patient's face, it can be fixed inside the protective shell 10 by the bracket 11 for temporary storage. The disinfection device 12 can sterilize and disinfect the mask 9 and the matching tubing 8 to prevent infection of the mask 9. The activated carbon plate 15 and the drying granules 16 keep the inside of the protective shell 10 dry and prevent the growth of bacteria due to moisture inside the protective shell 10.
[0026] Example 2: Refer to Figure 1-2 and Figure 4 In another preferred embodiment of this utility model, based on embodiment 1, the mixing mechanism includes a mixing chamber 5, which is fixedly connected to the second tube. A humidifying device 7 is fixedly connected to one side of the mixing chamber 5. A heating element 6 is fixedly installed inside the mixing chamber 5. The heating element 6 has a circular ring structure, and its outer surface is evenly distributed with edges along its circumference, as shown in the attached figure. The overall structure of the heating element 6 is dispersed. When the mixed gas passes through the heating element 6, the gas comes into contact with the surface of the heating element 6, which can uniformly and effectively heat the gas. The shape of the heating element 6 is not limited to the shape shown in this embodiment and can be other shapes. The heating element 6 is used according to specific needs, and is only used when heating is possible and the patient needs heating. In addition, regardless of whether the mixed gas needs to be heated, when the mixed gas passes through the heating element 6, the oxygen and anesthetic gas can be fully mixed under the blocking and diffusion effect of the heating element 6.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
