COVID-19 Important instruction:
COVID-19 full form is Corona Virus Disease 2019 is an infectious disease caused by the severe acute respiratory syndrome SARS-COV-2 called Corona Virus 2. COVID-19 firstly identified in December 2019 in Wuhan city of China and after that it spread globally, resulting in ongoing pandemic for worldwide. The symptoms of COVID-19 is fever, cough, fatigue, shortness of breath, and loss of smell and taste. The virus spreads mainly through close contact between individuals via tiny droplets produced by coughing, sneezing, and talking. The droplet usually falls to the ground or onto any nearby surfaces rather than travelling through the air. People may become infected by touching the COVID-19 exposed surfaces and touching their faces.
STAY HOME, STAY SAFE
Preventive measures against COVID-19:
- Frequently washing hands
- Frequent use of sanitizer when you touch any surface outside.
- Maintain social distance.
- Home quarantine especially those who have some mild symptoms.
- Keeping unwashed hand away form nose, and face.
- If possible avoid going out
Mechanical Project Ideas for Students:
1. Foot-operated sanitizer dispenser
The purpose of this invention in pandemic time is to control the spread of coronavirus from an infected person to others while using the same sanitizer bottle. This is mainly designed for highly populated places such as a business hub, Hospitals, Office, Companies, Banks and other public places.
With this device, the person used sensitizer without touching the bottle. A person presses the pedal with the foot and the bottle would dispense the liquid.
In these devices, different size of sanitizer bottle can be used range up to 250 ml to 1 litre.
The COVID-19 pandemic has produced critical shortages of ventilator worldwide. A mechanical ventilator is a system that delivers mechanical ventilation by pushing breathable air in and out of the lungs that can provide breathing to a patient who is unable to breathe or is difficult to breathe. Modern ventilators are microprocessor-controlled computerised devices, but a simple, hand-operated mask may also be used to ventilate patients.
This ventilator consists of a tank or compressor for compressible air, supplies of air and oxygen, a series of valves and tubes, and a reusable circuit for patients.
3. Sanitisation disinfection gate: (Sanitisation Booth)
It is one type of tunnel used to reduce bacteria and unwanted viruses from clothes or the outer body of the objects. It can be made up of metal as well as plastic. Stainless steel board, spray nozzle, motion sensor, electrically controlled agricultural sprayer, piping, timer, relay circuit are the key components used for making this setup.
These devices can be used for public places like hospitals, bus stations, railway stations, malls, companies, cinema halls, temples, parks, etc.
This device can be used for cleaning the home surrounding. The spraying is done by labour carrying backpack type sprayer. This type of sprayer requires more human effort. The main objective of this type of sprayer pump is a modification of agriculture sprayer for sanitising home surrounding frequently without using hands for pumping.
It consists of bicycle spoked wheel which connected with an oscillating hand pump lever using a chain and sprocket mechanism.
