COVID-19 PPE Solutions

COVID-19 PPE Solutions - open-source assistive technology concept by the Coronavirus (COVID-19) community

About this project

The NanoHack V2 is an open-source respirator mask. Designed by Copper3D, a TOM:Chile Partner (https://copper3d.com/hackthepandemic/). This design is meant to be used with Copper3D active PLA.

Please see the resources section for more information and disclaimers.

The challenge

Due to the SARS-COV-2 pandemic, the supply of facemasks is extremely limited, especially to the healthcare professionals and caretakers who need them most. The team is working on V2 of a reusable, modular face mask made from antibacterial PLA with a lifecycle that could outlast a virus.

Who it helps

Due to COVID19, Medical facilities worldwide are facing a dire shortage of face shields, N95 masks, and other personal protective equipment. Face Shields are not a replacement for N95 masks, however they do act as a protective physical barrier for healthcare workers's faces when dealing with patients' bodily fluids. Many conventional manufacturers have suspended production to follow government-mandated social distancing or run into supply chain issues due to the disruption in thre global econonmy. The Maker Community has committed to enacting Plan C: filling in the gap with an global network of independent DIY fabricators.

CLAIMS ABOUT NANOHACK:

The purpose of the NanoMask is to offer the general population a degree of protection against airborne particles and to prevent the spread of liquid aerosols that could contaminate the airways.

It is not an N95 mask. It is a face mask and should not be considered as a PPE.

If you are a healthcare professional, you should use it as a last resort device: you cannot manipulate airways such as intubation, mechanical ventilation, fiberoptic bronchoscopy, and similar procedures.

You can use it in common spaces.

It should be used for a maximum of 8 hours and change the non-woven filter once a day. After handling the active filter, you should wash your hands and follow precautions as recommended by the health authority.

Nanohack is a polymer-based device, we recommend using PLACTIVE® (PLA based material) for the monoblock structure and MDflex® (TPU based material) to print the outer rim. With this setup, you can have a comfortable mask with a good seal.

We understand that there may eventually be complex access to MDflex® in some parts of the world. This is why we have released a version with an integrated rim into the monoblock structure. With this solution, you can obtain a structure that fits properly but that must be complemented with some additional sealant and hypoallergenic cushioned tapes for nose and cheeks, especially if it is going to be used for long periods of time.

Keep in mind also that if you leave the elastic bands very tight it can hurt you, we don’t want the use of NanoHack to be counterproductive or cause you discomfort.

The NanoHack was designed to fit a 12 cm height face very well, measured from the tip of the chin to the ocular plane, a horizontal line that passes just between the eyes, and a distance between cheekbones (measured straight above the nose) also 12 cm.

We understand that all faces are different. If your face is smaller or larger than these measurements, we suggest rescaling the model by 5% or 10% so that there is a perfect fit for your face.
