[0027] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0028] Embodiment 1

[0029] Referring to Figures 1-4 , this is the first embodiment of the present utility model, which provides a laryngeal anesthesia nebulizer. This laryngeal anesthesia nebulizer includes a measuring cup 1, a spray tube 2 installed on the top of the measuring cup 1, and a nozzle 3 installed at one end of the spray tube 2. Grooves 21 are formed on the surfaces of the spray tube 2 and the nozzle 3. The grooves 21 are located at the adjacent position of the spray tube 2 and the nozzle 3. A disassembly and assembly part 4 is installed at the connection of the spray tube 2 and the nozzle 3;

[0030] The disassembly and assembly part 4 includes a sleeve 41 sleeved on the surfaces of the nozzle 2 and the spray head 3. A positioning groove 42 is formed inside the sleeve 41. One ends of the nozzle 2 and the spray head 3 are located inside the positioning groove 42 and are movably sleeved thereon. A clamping groove 43 is fixedly connected to the inner side of the sleeve 41 and on one side of the positioning groove 42. The clamping groove 43 is located on the surface of the groove 21 and is movably connected thereto. A elastic rubber band 46 is sleeved on the surface of the sleeve 41. The clamping groove 43 and the groove 21 are connected by the elastic rubber band 46. The sleeve 41 is made of a flexible material, and the elastic force of the elastic rubber band 46 can make the clamping groove 43 and the groove 21 be clamped. At the same time, the positioning groove 42 can position the spray head 3 and the nozzle 2 to ensure the stability during installation.

[0031] A clamping slot 45 is formed on the surface of the sleeve 41. The elastic rubber band 46 is located on the surface of the clamping slot 45. The clamping slot 45 can facilitate the elastic rubber band 46 to press the clamping groove 43 into the inside of the groove 21. The clamping slot 45, the clamping groove 43 and the groove 21 are vertically arranged, which can improve the simplicity during operation.

[0032] A sealing ring 44 is fixedly connected to the inner side of the sleeve 41. The sealing ring 44 is located inside the clamping groove 43. A flow control part 5 is installed on the surface of the nozzle 2, which can facilitate the connection between the nozzle 2 and the spray head 3 and prevent liquid leakage, thereby improving its sealing performance.

[0033] During the use process, connect the sleeve 41 with the nozzle 2 and the spray head 3, so that one ends of the spray head 2 and the nozzle 3 are located inside the clamping groove 43. Then, sleeve the elastic rubber band 46 on the surface of the clamping slot 45. At this time, the clamping slot 45 will slowly contract under pressure until it is located inside the groove 21 and fits tightly with it. In this way, the installation of the two can be completed. At the same time, the sealing ring 44 will fit tightly with the outer sides of the nozzle 2 and the spray head 3 to achieve a sealing effect, thereby improving the sealing performance. When disassembling, just remove the elastic rubber band 46. When the spraying operation is completed, the elastic rubber band 46 can be removed and then the nozzle 2 and the spray head 3 can be separated. When operating again, the quick installation can be completed through the above installation method, so as to facilitate the cleaning and disinfection of the spray head 3, reduce the risk of cross-infection of the laryngeal anesthesia nebulizer, and by this method, the time of medical staff can be saved, thereby improving the work efficiency.

[0034] Embodiment 2

[0035] Refer to Figures 1-7 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is:

[0036] The metering member 5 includes a spherical shell 51 fixed to the surface of the nozzle 2. A sleeve shell 52 is fixedly connected to the top of the spherical shell 51. A ball valve 53 is movably connected inside the spherical shell 51. A rotating shaft 55 is fixedly connected to the top of the ball valve 53. The rotating shaft 55 extends to the top of the spherical shell 51 and the sleeve shell 52. The metering member 5 is located on one side of the disassembly and assembly member 4 and is close to the side of the measuring cup 1.

[0037] Through holes 54 are provided inside both the spherical shell 51 and the ball valve 53. The through holes 54 communicate with the nozzle 2, which facilitates the flow of liquid.

[0038] Sealing rings 56 and rotating rings 57 are fixedly connected to the surface of the rotating shaft 55. The sealing ring 56 is located inside the spherical shell 51 and is movably connected to it. The rotating ring 57 is located inside the sleeve shell 52 and is movably connected to it. The setting of the sealing ring 56 can ensure the sealing performance of the nozzle 2.

[0039] Annularly arrayed rubber balls 58 are fixedly connected to the surface of the rotating ring 57. The rubber balls 58 are located inside the sleeve shell 52 and are movably connected to it. The rubber balls 58 are in close fit with the inner side of the sleeve shell 52. The rubber balls 58 can increase the damping of the rotating shaft 55 and prevent it from rotating by itself, thereby improving the working efficiency.

[0040] Rubber blocks 59 are fixedly connected to the surface of the rotating shaft 55. The rubber blocks 59 are located on the top of the rotating ring 57 and are annularly arrayed. They can increase the friction with the hand and reduce the force on the hand, thereby facilitating the adjustment of the ball valve 53 and improving the working efficiency.

[0041] During use, the state of the ball valve 53 can be adjusted according to the anesthetic level of the patient. When the anesthetic level is relatively high, the rotating shaft 55 can be rotated to drive the ball valve 53 to rotate until the through hole 54 opened inside it coincides with the through hole 54 opened in the spherical shell 51, so as to achieve the fastest flow of the medicine, that is, more medicine will be sprayed. Similarly, when the anesthetic level is relatively low, the area where the through hole 54 inside it communicates with the through hole 54 in the spherical shell 51 can be reduced by rotating the rotating shaft 55. In this way, the purpose of controlling the flow rate of the spray can be achieved, making the laryngeal anesthesia sprayer safer, more effective and more accurate during surgery and examination, and further improving the working efficiency.

[0042] The remaining structure is the same as that of Embodiment 1.
