[0032] The specific implementation process is as follows:

[0033] In use, the medical staff closes the manual check valve 16, and uses a needle tube to connect with the medicine delivery tube 44, and injects the anesthetic into the medicine storage cavity 6 through the medicine delivery tube 44, and at the same time, the air in the medicine storage cavity 6 enters the air storage cavity 5, so that the first piston 11 in the air storage cavity 5 moves downward, and then the moving rod 31 drives the trigger block 32 to move downward, and in this process, the moving tip 30 moves into the firing cavity 46 under the action of the third spring 29, and when the anesthetic is completely injected into the medicine storage cavity 6, the medical staff aligns the first recess 27 of the connecting tube 22 with the impact rod 33, and then connects the connecting tube 22 with the mist outlet 2, and in the connecting process, the rubber strip 25 arranged on the inner wall of the connecting tube 22 is extruded to deform under the action of the fixing ring 24, so that the connecting tube 22 is firmly fixed at the mist outlet 2, and then the medical staff rotates the connecting tube 22 along the semicircular groove 41 to the second recess 42, and in the rotating process of the connecting tube 22, the end of the impact rod 33 abuts against the outer wall of the arc-shaped block 43, and extrudes the impact rod 33 downward, until the circular truncated cone 39 at the lower end of the impact rod 33 contacts the inclined surface of the special-shaped block 35, and with the continuous downward movement of the impact rod 33, the arc-shaped surface of the circular truncated cone 39 extrudes the special-shaped block 35, so that the moving tip 30 extrudes the third spring 29 and moves to the right, until the circular truncated cone 39 and the special-shaped block 35 are completely disengaged, and then the moving tip 30 moves to the left under the action of the third spring 29 to reset, at this time, the special-shaped block 35 is located above the circular truncated cone 39, and when the second recess 42 rotates to the upper end of the impact rod 33, the impact rod 33 moves upward under the action of the fourth spring 38, until the circular truncated cone 39 at the lower end of the impact rod 33 abuts against the special-shaped block 35, at this time, the impact rod 33 does not contact the fixing ring 24, and the fourth spring 38 is in a compressed state;

[0034] Subsequently, the medical staff opens the manual one-way valve 16, so that when the first piston 11 pushes the gas into the storage cavity 6, the anesthetic agent is forced to enter the dosing cavity 7 through the manual one-way valve 16, under the action of the pressure provided by the gas storage cavity 5, the second piston 15 moves to the positioning ring 17 until it abuts against the positioning ring 17, and under the action of the pressure one-way valve 18, the anesthetic agent in the dosing cavity 7 cannot enter the atomization cavity 8, at this time the amount of anesthetic agent entering the dosing cavity 7 is certain, and the medical staff applies pressure to the dosing cavity 7 by pushing the push rod 14, so that the pressure in the dosing cavity 7 is greater than the opening pressure of the pressure one-way valve 18, and then the anesthetic agent is pushed into the spray cavity for spraying, when the anesthetic agent in the dosing cavity 7 is completely pushed into the spray cavity, the medical staff releases the push rod 14, at this time the gas storage cavity 5 continues to apply pressure to the storage cavity 6, so that the anesthetic agent in the storage cavity 6 enters the dosing cavity 7, thereby pushing the push rod 14 to abut against the positioning ring 17 again, facilitating the medical staff to continue to push the anesthetic agent, in this process, the medical staff can deliver a certain amount of anesthetic agent to the spray cavity every time the push rod 14 is pushed, thereby facilitating the medical staff to accurately control the anesthetic agent and improving the safety of the anesthetic operation.

[0035] In the process of spraying, every time the medical staff pushes the push rod 14, the first piston 11 in the gas storage cavity 5 will move upward a certain distance under the action of the first spring 10, thereby pushing the anesthetic agent in the storage cavity 6 to the dosing cavity 7, and then reaching equilibrium, in the process of upward movement of the first piston 11, the inclined surface at the right end of the contact block will abut against the trapezoidal groove 34, and the inclined surface at the right end of the contact block will extrude the trapezoidal groove 34, so that the moving tip 30 moves to the right end, thereby driving the special-shaped block 35 to move to the right, when the air in the gas storage cavity 5 is completely delivered to the storage cavity 6, that is, all the anesthetic agent in the storage cavity 6 enters the dosing cavity 7, at this time the special-shaped block 35 is separated from the circular truncated cone 39, so that the fourth spring 38 is rapidly released from the compressed state, thereby pushing the impact rod 33 to move upward, when the end of the impact rod 33 hits the elastic membrane, the elastic membrane deforms to make the end of the impact rod 33 hit the fixed ring 24, thereby causing the fixed ring 24 to break, and the broken fixed ring 24 is still in the installation cavity, the elastic membrane locks the broken pieces of the fixed ring 24 in the installation groove 26, preventing the broken pieces of the fixed ring 24 from leaking, and the broken fixed ring 24 no longer extrudes the rubber strip 25, so that the medical staff can easily separate the connecting pipe 22 from the spray port, facilitating the replacement of the connecting piece and saving the time spent on disassembly.

[0036] Example 2

[0037] Embodiment 2 is substantially the same as embodiment 1, except that a controller is arranged in the housing 19, the controller is electrically connected with the air pump 20, and a pressure sensor is arranged at the end of the first piston 11 away from the first spring 10. The pressure sensor can monitor the change of the air pressure in the air storage cavity 5, and the controller is electrically connected with the pressure sensor. Since the amount of anesthetic required for each spray is different, the time required for each spray is also different. If the amount of anesthetic required for each spray is small, and the time of spraying is too long, too much gas will be blown into the patient's body. If the amount of anesthetic required for each spray is large, and the time of spraying is not enough, the spraying effect will be poor, which will affect the normal operation of the surgery. By arranging the pressure sensor on the first piston 11, the change of the pressure in the air storage cavity 5 is detected by the pressure sensor, the number of times that the medical staff pushes the push rod 14 is identified, so as to determine the amount of anesthetic required for each spray. Then, the controller controls the working time of the air pump 20, so as to accurately control the time of spraying, and reduce the discomfort of the patient.
