Innovative Sanitization Chamber for Covid19
Dr. Manisha Mhetre1 , Mohini Lad2
Duringcompletely.thisoutbreak, poor sanitation and hygiene practises may lead to an increase in infection rates. This corona virus can survive in aerosols for up to 3 hours, 4 hours on copper surfaces, 3 days on steel and plastic surfaces, and 24 hours on cardboard surfaces. Without propersanitization,thepathogencanspreadswiftlythrough touch surfaces and the air. Effective surface and air disinfection can be ensured by early regulation and counteractionoffurtherviruspropagation.COVID 19viral infections are effective with 0.1 percent hypochlorite solutionin1minute,accordingtotheliterature.Whenthe temperature and humidity are high, the corona virus transmissionisreducedanddiminished.[2]

So,there'sa requirement ofa strongdisinfection systemto interruptthe chain of the virus from diffusing,regardless ofthe sanitation of people. An electronic sanitization chamber can operate contactless sanitationofallitemsorobjects.Thesanitizationchamber shouldbe autonomous,irrespectiveofanykind ofobjects needtobesanitizedandwithoutindividuals’interferencefor catchingtheailmentonthebaseofitemsorobjects.Different sanitizationmethodsareavailablelikehydrogenperoxide mistcanbeusedtodisinfecttheitemorobject.Subsequently UV light can also be utilized for disinfection purposes; however, selection of the wavelength of UV radiation is exceptionallycrucial.Ifacalculativechoiceisnottakenthen itmightbeunsafeandserioustothehealth,skin,andeyesof thehumanbeings.Thesetechniquesareutilizedseparately indifferentinstrumentsforsanitization.

Two chambers with three different disinfection methods are provided to make the tunnel effective and efficient.

As a disinfection, use a dilute solution of an approved chemical or any Ayurvedic/herbal disinfectant.

This paper depicts a multipurpose autonomous sanitization chamber to clean different items or objects we bring from outside or those which interact with the COVID 19 infection like cell phones, PCs, vegetables, organic products, staple things, and so forth. To make the chamber powerful and profoundly proficient, it has been given three sterilization modes whose time goes from 5 minutes to 15 minutes. Because of the numerous modes, the chance of killing the infection is very high. The first sanitizing mode is for 5 minutes in which the UV C light will get ON. In the second sanitizing mode that is for 10 minutes in which UV C lights will turn ON for 8 minutes and the Mist will turn ON for 2 minutes. Also, for the last cleaning mode that is for 15 minutes in which the heater will turn ON for 5 minutes, UV C light for 8 minutes and Mist for 2 minutes. When the individual keeps any item or object in the chamber, that item is presented to a specific cleaning measure contingent on the mode chosen by the individual. The chamber works autonomously by identifying the presence of an item or object with the help of an ultrasonic sensor, and by recognizing the situation of the chamber entryway. The chamber is referred to as the 'Multipurpose Sanitization Chamber'.
