③ when the external oxygen or air source 2 is connected, the controller 10 sends out the work order at the same time, the power supply line 14 and the power supply line 15 of the high pressure generator supply power at the same time, the electromagnetic valve 304 is opened, the high pressure generator 308 operates, the generated high pressure ozone gas enters the oxygen terminal 102 of the respirator through the output terminal 302 and the high pressure output hose 7, the inhalation loop of the respirator is sterilized, the pressure sensor 305 connected in series in the loop also synchronously detects whether the pressure value in the loop is normal, if normal all work is continuously executed, if not normal, alarm information is sent out, after the controller 10 receives the information, the user is informed of the need of immediate power off for repair.

④ according to the principle of the simulated breathing mechanism of fig. 4, when the ventilator 1 to be disinfected is in operation mode, the simulated breathing mechanism also must operate according to this breathing mode, when the ventilator operates during inspiration, ozone gas enters from the inspiration end 103 of the ventilator through the fourth threaded tube 903, the gas transmission port 904, the destroyer 902 into a port of the Y-shaped three-way hose 409 and is introduced into the gas storage bag 406 through the gas nozzle 408, the gas storage bag 406 is slowly filled with gas over time, the gas storage bag 406 extends upward, the lower fixing plate 405 moves upward, the guide post 402, the spring 403 and the upper fixing plate 404 also move upward, when the upper fixing plate 404 contacts the limit screw 407, the upper fixing plate 404 is balanced under the effect of the limit screw 407 and the spring 403, stops moving, at this time, the lower fixing plate 405 and the guide post 402 continue to move upward, the spring 403 is compressed and deformed, when the spring reaches the compression range, the lower fixing plate 405 and the guide post 402 stop moving, when the ventilator 403 operates during expiration, the breathing cycle starts to rebound, the lower fixing plate 405 and the gas storage bag 402 and the ventilator returns to the sterilization cycle of the breathing device 802, when the ventilator stops, the ventilator stops operating frequency of the ventilator, and the ventilator returns to the disinfection cycle, the breathing device 802, and the ventilator stops.

⑤ at the same time, when the respirator 1 to be disinfected is in the disinfection working state, a part of the exhaust gas is discharged through the exhaust port 105 and is quickly discharged into the environment, and the multi-filtered, decomposed and destroyed exhaust gas completely meets the national standard.

The invention relates to a respirator inhalation loop disinfection device, which comprises a gas source providing mechanism, an ozone generating mechanism, a simulated breathing mechanism and a control mechanism, wherein the gas source providing mechanism and the ozone generating mechanism provide high-pressure ozone gas for the disinfection device, the high-pressure ozone gas is taken as a disinfection factor and is directly led into a respirator inhalation loop from a respirator oxygen terminal, and the internal loop of the respirator achieves the purpose of thorough disinfection by utilizing the wide-area disinfection effect of the ozone and the characteristic of no dead angle during propagation; the simulated respiratory mechanism replaces a common simulated artificial lung, so that the respirator operates in a conventional working mode in the disinfection process of the respirator, and no alarm information is generated in the disinfection process. The sterilization device for the breathing machine inhalation loop is quick in sterilization and simple in operation, and can be suitable for sterilization of different breathing machines.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
