Introduction: COVID Killer Glove
I am Amogh, currently a high school junior (11th grader).
Introduction and Purpose:
2020 has been a challenging year for everyone. The pandemic, COVID19, has spread uncontrollably and exponentially to tens of millions of people worldwide. One of the major reasons why the Coronavirus has spread so much is because of its transmission through contact; people may touch contaminated surfaces in public, and then touch their face unknowingly. To prevent this, virus must be killed right then and there before it spreads. I came up this idea and designed 'COVID Killer Glove' to kill any virus that may be present on the surface of contact. This Instructable can help reduce the spread of COVID19.
Covid killer glove secretes sanitizer and kills any virus present on the surface or object you come in contact with. The glove does not leak, and the secreted sanitizer dries out in a couple of minutes. It is also designed to self-clean itself because of the sanitizer.
The following are some of the scenarios how and where you can use this glove:
You can wear it while using public transport when opening bus doors with door-handles, holding railings on trains, etc.
You could wear the glove while entering offices or other public places where you have to open doors, use elevators, hold staircase handrails, etc.
You can keep it ready at the front door of your house and use it to bring in the deliveries from stores to inside your house.
- You could use it in the gym if you are using treadmills, stairmasters, or other types of machines.
- Air hosts can use the gloves while serving travelers on planes.
You can use them it in the airport to push baggage carts or to move luggage around.
You can use the glove in theme parks where places and equipment are touched by many users. The glove can be used both by the employees and the visitors.
Factory and construction workers can also use these gloves while using tools shared with other workers.
- You may use it in grocery stores to hold carts, carry bags, etc.
In a general view, the glove can be used and will be effective in any public place where many people are.
(Please refer to the picture of materials included in this section. Links are embedded in some names of the materials below indicating from where it can be bought)
1. Rubber Gloves- 2 (One glove of your hand size and the other +1 of your current your hand size so that they fit each other; for example, if your hand size is small, get one pair of small-sized gloves and another pair of medium-sized gloves. Both the gloves used will be for the same hand, 2 right-hand gloves or 2 left-hand gloves, not a pair!).
The smaller glove is inserted into the bigger glove with 3-layers of thin sponges in-between stitched together. The glove has to be made of rubber, not cloth or any other material, as the secreted sanitizer should not be absorbed or it should not damage the glove. In addition, the outer glove's surface should be smooth so that the sanitizer does not stay in the grooves. If this surface is not smooth, you can turn this outer glove inside out (so the inner layer, the layer where you normally put your hand in, will be on the outside. As the inner layer is usually smooth, the problem will be solved).
2. New Thin Sponge Wipes - 3 thin layers of sponges,Scotch-Brite sponges work well.
These are needed to store and secrete sanitizer in between the gloves. It allows sanitizer out only when pressure is applied to the palm side of the hand. The middle sponge in the sponge layer has grooves that helps sanitizer flow into all parts of the glove.
3.Sanitizer - any hand sanitizer with 60% or more alcohol
The sanitizer used to kill the virus, gets secreted from the small pores on the outer glove. A free-flowing, non-viscous, high alcohol sanitizer is recommended for effectiveness and usability.
To fill the sponges in the glove with sanitizer, you need a short soft tube to direct the sanitizer into the sponge and also to refill.
5. Pin (available at home)
You will need a pin to poke holes on the outer glove. This is how you will create pores that let the sanitizer to ooze out when pressure is applied to the glove.
6. Marker (available at home)
You will use this to outline the shape of the hand on the sponge to make it easier to cut.
7. Scissors (available at home)
You will use a pair of scissors to cut the sponges in the shape of a hand. You will also need to cut the grooves in the middle sponge in the sponge layer so that the sanitizer can flow and spread through out.
8. Thread and Needle (available at home)
All the 3 sponges cut out in the shape of the hand needs to be sewed together with thread and needle. Also, the soft pipe needs to be sewed into the sponge layer.
You will use this to seal the edge of the sponge layer at the bottom of the palm. Also, you will use the putty to plug and close the short tube or straw to prevent the sanitizer from leaking.
Alternatively, you can seal the edges of the gloves using strong glue or adhesives or heat the gloves together using an ironing box (with waxed oven paper so the glove rubber doesn't stick to the surface of the ironing box).
Step 1: Outline and Cut Your Hand Shape on the Sponges.
Stack up and align all 3 sponges (also called sponge layers). Using a marker, outline the hand you are making the glove for on the top sponge. Keep you fingers the way they would be in the glove, not to spread or close to each other. Once the outline is drawn, hold the three sponge layers firmly and cut out your hand shape using a pair of scissors.
Step 2: Cut Grooves in the Middle Sponge Layer.
In the middle sponge layer, cut out grooves that extend from the base of the hand to each finger as shown in the pictures. Make sure they are thick enough so sanitizer and flow through them, and make sure they are thin enough so they can hold enough sanitizer. A thickness of 3-5 mm for each groove should work.
Step 3: Sew the Sponge Layers Together to Create a Set.
Stack up all three sponge layers (so that the layer with grooves is in the middle) and sew their edges as shown in the images. Do not sew their edges at the bottom-middle of the palm. This will allow you to insert the straw at the base of the hand to refill the glove with sanitizer. This will be referred to as the sponge layer in the glove.
Step 4: Poke Holes on the Outer (bigger) Glove.
Take a pin and poke holes on the front side of the bigger glove, so the sanitizer can come out when you put pressure on it. The holes should be spaced evenly across the fingers and palm. Also stop applying pressure on the pin as soon as its tip penetrates the rubber glove. Try to make the holes small, so they do not leak.
Step 5: Insert and Secure the Straw.
Cut a tube or straw so that it is an inch and a half long. Insert this straw into the groove (formed by cutting grooves in the middle sponge layer in the 2nd step) at the base of the sponge set(which you left unstiched in the 3rd step) as shown in the pictures. Sew on both sides of the tube with the sponge set so that the straw is held tightly.
Step 6: Insert the Sponge Set and the Inner Glove Into the Outer Glove.
Insert the sponge set into the outer (bigger) glove by properly inserting it into the glove: each finger in the sponge set should be in the same finger of the glove. After that, wear the inner glove on your hand and insert it inside the outer glove but behind the sponge set. Also, make sure that all the inner glove fingers are inserted in the outer glove fingers with the sponge set in-between. Align all of them (the inner glove, sponge set, and outer glove) properly, as shown in the pictures.
Step 7: Seal the Front and Back, Inside the Glove.
There are a few ways you can seal the front and back of the inner and outer gloves together. The three I recommend are: using a sticky putty material, heating/melting the rubber layers of glove, and using an alcohol-resistant adhesive.
To seal the front, back and inside of the glove, roll some putty into 3 thick threads (2 short and 1 long) as shown. Insert two short putty threads just under the sponge set inside the big glove and in the front part of the glove. Press slightly from the outside, so the putty sticks to the sponge set and the gloves as shown. This is done to block any leakage of sanitizer from the sponge. Similarly, seal the back of the big glove using the long putty thread by inserting it between the inner and outer glove as shown.
You can also accomplish the above by melting the rubber gloves (with an ironing box for example) in lieu of the putty, but make sure you put cardboard or wax paper in the inner glove (where you would normally put your hand in) to prevent the rubber layers from sticking to other parts of the glove or ironing box. This heat press can be the best way to seal if done properly as in big scale manufacturing but may not be appropriate to be done at homes.
The third way to seal is by applying alcohol-resistant adhesive in the same places where you place the putty. However it would be better if you add this adhesive right outside the edges of the sponge set, so no sanitizer can leak.
Step 8: Fill the Sponge Layer in the Glove With Sanitizer.
Once the inside of the glove is sealed, pour the sanitizer through the tube as shown in the picture. Make sure the sanitizer spreads to all parts of the fingers in the glove. Sanitizer flows well if it is not too viscous. Also using a funnel makes it easier to pour.
Step 9: Close the Straw With a Putty Plug.
Get some more of adhesive putty, shape it into conical shaped plug as shown, and close the end of the straw, so the sanitizer doesn't leak.
Step 10: Conclusion - Wear It, Use It and Be Safe!
Wear the glove on your hand. Then apply a bit of a pressure on a surface to see if the glove works; more specifically, check if sanitizer come out of the glove’s pores. Once you have confirmed that the glove is working, you can use it wherever you want. This glove will reduce your chances of contracting COVID 19, or any viral or bacterial infection, by contact.
Don't worry, if the holes you made are small enough, the glove will not leak when no pressure is applied as the elasticity of the rubber gloves prevents sanitizer oozing out of the pores.
Once you make the glove and use it, you can always refill the glove as and when the sanitizer is depleted. It is not safe to share this glove with other people as the inner surface of the inner glove is not sanitized. Also, be cautious near the fires as alcohol can catch fire.
