The working flow of the medical channel for atomizing, spraying and disinfecting by using protective gas and disinfectant is as follows:
entering a pollution area: the medical staff who has worn good air sac formula malleation medical protective clothing or other medical protective clothing, at first trigger infrared correlation detector when getting into the import floodgate machine, the passageway control system begins to start into the district procedure by the standby state immediately, passageway yellow signal lamp lights, medical staff is after two-dimensional code or face identification, current green signal lamp lights, open gate and import passageway sealing door, the white light in the passageway box lights immediately, after medical staff gets into the passageway box, the system self-closing passageway box import sealing door, open passageway box export sealing door again, the system is automatic to spraying nitrogen protection gas in the passageway box simultaneously, keep being the malleation state in the passageway box, in order to avoid the contaminated area air to get into the passageway box. After the medical staff leaves the channel box body, the channel outlet sealing door and the nitrogen spraying are closed, and the entering process is terminated and is in standby.
And (4) discharging from a pollution area: because the sterilization mode adopted by the invention is to use the protective gas nitrogen and 70% -75% ethanol for atomization spray sterilization, when the atomization spray sterilization is carried out, the sterilized medical personnel wearing the bubble bag type positive pressure medical protective clothing can not breathe to the outside, therefore, when the medical personnel goes out of the pollution area, the electric respirator needs to be closed, the micro oxygen tank carried in the protective clothing is opened for oxygen supply, after the medical personnel enters the channel box body, the pipe orifice of the one-way exhaust valve on the protective clothing needs to be communicated with the one-way exhaust pipe of the protective clothing in the channel box body, and an expiration exhaust passage which is completely isolated and independent from the inner space of the sealed channel box body is formed. Therefore, the invention is only suitable for medical care personnel wearing the bubble bag type positive pressure medical protective clothing, and the medical care personnel wearing other common medical protective clothing and isolation clothes can not use the protective clothing because the medical care personnel can not breathe normally during spraying and disinfection.
The specific working process when the area is out of the pollution area is as follows: when a medical worker wearing the bubble bag type positive pressure medical protective clothing enters an exit gate, an infrared correlation detector is triggered, a system starts an exit program from a standby state, a yellow passing signal lamp is turned on, two-dimension code or face identity recognition and whether the electric respirator is shut down are started, after the two-dimension code or face identity recognition is passed and the electric respirator is confirmed to be shut down, the green passing signal lamp is turned on, the exit gate door and the channel exit sealing door are opened, the white illuminating lamp in the channel box body is turned on at the same time, the exit sealing door is closed after the medical personnel enters, the voice horn prompts the medical personnel to connect the one-way exhaust pipe of the protective clothing, after the system automatically detects that the expiration exhaust passage is communicated, the voice prompt starts the spraying and disinfecting operation, the white illuminating lamp is turned off immediately, the light green working indicating lamp is turned on, and the system automatically starts nitrogen (N).2) The protective gas sprays, several seconds later, when the mixed gas oxygen content in the passageway box is diluted and is reduced to below 14% safety value, the work pilot lamp is changed into light pink by light green, and the system begins to atomize continuously or discontinuously to the medical personnel who wear the medical protective clothing of bubble bag formula malleation and sprays70% -75% ethanol disinfection solution, spraying for 3-5 minutes for disinfection, stopping, changing the light pink working indicator light into light green, and continuing nitrogen (N) in the system2) The protective gas sprays for 0.5-1 minute, when medical personnel protective clothing is dried, the spraying is stopped when the concentration of ethanol in the mixed gas of the channel box body is reduced to be below 3.0%, the light green work indicator lamp is turned off immediately, the white illuminating lamp is turned on, the voice horn prompts the completion of disinfection, the inlet channel sealing door is automatically opened by the system, after the medical personnel leaves the channel box body, the inlet channel sealing door is closed, the inlet gate is opened, and when the medical personnel leaves the inlet gate and triggers the inlet infrared correlation detector, the channel system stops the exit program and is in standby.
In addition, in the above-mentioned nitrogen gas (N)2) The used nitrogen (N) in the operation process of the protective gas spraying recovery system and the 70% -75% ethanol spraying disinfection recovery system2) And 70% -75% ethanol, and the system automatically and synchronously recycles and reuses.
The technical scheme is only explained by using a single channel, but in practical application, the passing capacity of the single channel is difficult to meet the actual passing flow demand of hospitals, particularly the passing capacity of the channel needs to be improved when medical staff go on and off duty, so that the hospitals can combine the single channels described in the technical scheme side by side according to the actual needs to form a compound channel in a mode of constructing 2-4 channels side by side so as to greatly improve the passing efficiency of the channel, the compound channel is only one form of the form combination of the invention, the principle of the compound channel is not different from that of the single channel, and the compound channel also belongs to the protection scope of the invention.
Compared with the prior hospital medical care channel technology, the invention has the beneficial effects that:
1. the medical treatment system overcomes the defects of the existing medical treatment channel of the hospital, eliminates the problems of complicated procedures, long time consumption and poor safety guarantee in a pollution area, relieves the burden and pain of medical workers, and reduces the management difficulty and cost for the epidemic prevention safety management of the hospital;
2. the device realizes the matching with the equipment application of the bubble bag type positive pressure medical protective clothing, and provides basic equipment matching guarantee for popularizing and applying the bubble bag type positive pressure medical protective clothing and exerting the advantages of the bubble bag type positive pressure medical protective clothing in safety, comfort and economy.
