Example 6:
The disinfectant kills novel coronaviruses, which are RNA novel coronaviruses with envelope, have poor heat resistance, and the outer envelope is sensitive to organic solvents and disinfectants. Once the envelope is destroyed by the disinfectant, the RNA is also very easy to degrade (e.g. hypochlorous acid generated by sodium hypochlorite in 84 disinfectant in aqueous solution can decompose nascent oxygen, has very strong oxidizing property and can oxidize nucleic acid substances of the novel coronavirus), thereby inactivating the novel coronavirus.
As shown in fig. 1, 3, 4, 12, 13 and 14, a connecting hole 13 is formed in the middle of the arch-shaped main body 1, and the air exhaust device 200 is connected to the connecting hole 13 of the arch-shaped main body through a flange.
The working principle of the disinfectant sterilizing device in the invention is that a proper amount of disinfectant is filled in a disinfectant barrel 203, a disinfectant barrel cover is covered and a second air guide pipe 204 is fixed, so that an air outlet of the second air guide pipe 204 is arranged below the disinfectant liquid level [ the air outlet of the second air guide pipe 204 is arranged below the disinfectant liquid level and is close to the inner bottom surface of the disinfectant barrel 203 ].
In the present invention, the suction pump 202 is a unidirectional suction pump, and the suction direction thereof can be only outputted from the first air guide duct 201 to the second air guide duct 204 through the suction pump 202.
The air suction pump 202 can be designed into a plurality of air baffle circuits, and medical staff can adjust to proper gears according to actual demands. After the air suction pump 202 works, air in the cover main body 100 enters the disinfectant barrel 203 through the first air guide pipe 201, the air suction pump 202 and the second air guide pipe 204. The novel coronavirus in the cap body 100 will follow the air into and be killed by the sterilizing liquid. The invention filters the air draft system connected with the disinfectant barrel containing the novel coronavirus disinfectant capable of killing the new coronavirus, thereby avoiding the pollution of the extracted wind to the surrounding environment.
The filtering part is arranged at the air outlet of the disinfectant barrel 203, and can use a similar structure of the novel coronavirus prevention mask capable of exhausting and filtering [ such as an N95 mask ], and the filtering part designed here can prevent the novel coronavirus which is not killed from blocking the interior of the disinfectant barrel 203. If the novel non-killed coronavirus is required to be treated, the air outlet is closed, and the disinfectant barrel 203 is inverted, so that the novel coronavirus sterilizing treatment can be performed on the inner surface of the filtering part and the upper wall surface of the disinfectant barrel 203.
The exhaust device 200 of the invention can exhaust the air in the cover main body below the liquid level of the disinfectant in the disinfectant barrel by the operation of the exhaust pump, so that the air circulation in the cover main body can be accelerated, and the transmission of novel coronaviruses in the cover main body to the outside can be further reduced.
Example 7:
The disinfectant sterilizing device can be replaced by a heatable sterilizing device, the replacing part is a disinfectant barrel 203, the disinfectant barrel 203 is replaced by an electric kettle type heating structure, and the air inlet end of the electric kettle type heating structure is connected with an air exhaust device 200. The electric kettle type heating structure is used for containing water, and the heating part is used for heating the water to more than 56 ℃.
Since the novel coronavirus can be killed at a temperature above 56 ℃ and for at least 30 minutes of heating [ the higher the temperature, the shorter the time the novel coronavirus survives ].
Firstly, the electric kettle type heating structure heats water in the electric kettle type heating structure to more than 56 ℃ and continuously heats the water, then the air outlet end of the second air guide pipe 204 enters below the water surface, the air suction pump 202 is started, the novel coronavirus enters the water body, the water temperature which is more than 56 ℃ is kept to continuously kill the novel coronavirus [ the higher the temperature is, the shorter the survival time of the novel coronavirus is ].
The filtering part is installed at the air outlet of electric kettle, but filtering part can use similar exhaust filtration structure [ like N95 gauze mask ] that prevents novel coronavirus gauze mask is similar, and the novel coronavirus that the here design can make and not kill blocks inside the electric kettle, because last high temperature in the electric kettle, the novel coronavirus that is blocked can be killed along with the time.
The design of example 7 was able to accelerate the ventilation in the mask body and further reduce the transmission of the novel coronavirus in the mask body to the outside.
In summary, the cover body of the device of the present invention is provided with a plurality of partial windows, and the medical staff can open the protective cover to check or operate the patient, and after the operation is completed, the protective cover covers the openings. The device disclosed by the invention has the advantages that only the cover body at the part is opened when nursing different areas of a patient in a targeted manner, and the cover bodies at other parts are closed, so that the transmission of novel coronaviruses in the protective cover to the outside is reduced. The function of the arch side hole is that the cover part and the pipe part used for the breathing machine enter, and the design of the arch side hole effectively reduces the transmission of novel coronavirus in the protective cover to the outside. The novel coronavirus prevention gloves are designed on the protective cover plate, so that medical staff can operate medical equipment without opening the protective cover when checking patients, and the medical staff is not required to directly contact with the patients, thereby reducing the infection risk of the medical staff.
