3D-Printed Origami Tube for Low-Cost Ventilators

# data[].attributes.body
The world lately had to deal with this awful pandemic that killed so many people. As a nurse that works in COVID unit I realized how important are the ventilators and how lucky we are in USA that since is a country with little economic problems didn't have a shortage in ventilators. In other countries though this was a disaster. There were no enough ventilators for everyone. Medical practitioners had to choose who to save. The shortage in ventilators was global and not only in poor countries but also in countries like Italy, France, Spain.
I believe that this innovation could help to save many lives world wise.
This type of ventilator can be manufactured in less time than traditional ones and the cost is minimal. Therefore I strongly believe and hope that this innovation will be adopted world wise.

Portable 3D-printed ventilators being developed at SFU

Researchers at Simon Fraser University in Canada have developed a low-cost portable ventilator that uses a 3D-printed origami tube rather than a conventional airbag. The volume of the tube can be modified by changing the angles in the origami folding plates. As up to 95% of the components of the ventilator are 3D printable, the device can be created for approximately $200, compared with approximately $2000 for existing portable ventilators.

Ventilators have been a key tool during the COVID-19 pandemic, and shortages have inspired a variety of makeshift and innovative devices that have helped to save lives. While the worst effects of COVID-19 have been blunted by successful vaccination campaigns in many countries, millions of people do not yet have access to the vaccines, and the virus continues causing problems.

In many developing nations, lack of access to vaccines, healthcare facilities, and equipment could make the difference between life and death during the pandemic. There is an ongoing need for low-cost and portable medical equipment to treat COVID-19 patients in such regions, particularly in rural and remote locations.

While this latest technology is designed to be low-cost, it is far from makeshift, employing 3D printing and a unique origami design to create a small and portable ventilator. In the place of a simple bag, the ventilator includes a 3D printed origami tube in which origami folding plates interlock to form a tube that is smaller and stronger than the equivalent component in a conventional ventilator.

During operation, the tube is contracted to assist in breathing. As with so many devices intended for low-resource use, 3D printing was the key to the low cost of the technology. "In our portable origami ventilator, more than 95 per cent of components can be 3D printable, that's why it is really cost-efficient," said Woo Soo Kim, one of the developers of the new technology, in a press releas. "Other portable ventilators can cost over $2,000, but our 3D-printed ventilator can be produced for about $200."

The researchers hope that the technology could assist in low-resource or remote regions, where healthcare resources are scarce. They have partnered with a ventilator manufacturer with a view to scaling up production of the devices.

Pros

TIME
The speed of 3D printing means it’s possible for manufacturers to quickly create devices in response to patient demand. Traditional implants can take weeks to design and manufacture, especially if they need to be customized for a patient.

COST
3D printing is often cheaper — and sometimes faster — than standard manufacturing methods, which means manufacturers can rapidly design, print and test medical device prototypes

Cons
3D printing is not eco-friendly
Inconsistent quality of 3D printing objects

3D printers don't always produce top-of-the-line results. 3D-printed objects can vary slightly in dimensions, and some level of design noise — like texture or bumps when a surface needs to be smooth — may be introduced in the manufacturing process. In such cases, the noise and irregularities would need to be machined by a worker before the parts would be allowed to come into contact with patients.

3D printers are energy-intensive, limited in functionality compared to some traditional manufacturing methods.

According with Clifton Strengthsfinder my five strengths are: Input, Harmony, Individualization, Woo, Restorative.
For my team i will choose Carter-communication, Alice-achiever, Carlee-consistency, Daisy-developer, Fernando-focus.
I selected those because I need in my team someone able to focus on the project, an achiever, someone to develop a project and someone that has to communicate between all of us.
I believe that the strength Woo will help me to influence others  , Harmony will help me to lead  my team members in a harmonic way avoiding conflict. Input is the strength that will help to collect and archive more information about this project.
Individualization is the strength that helps me to take in consideration each individual unique qualities and use them for my project.
The last strength, Restorative will allow me to help resolve problems and conflicts. Will be able to identify and eradicate the problems that can appear during the project management.

Technology takes the art of origami into the fight against COVID-19

# data[].attributes.body
New research from the Additive Manufacturing Lab at Simon Fraser University in British Columbia is using origami to help the fight against the Covid-19 pandemic. Based on 3D-printed origami technology, their breakthrough could lead to inexpensive and portable ventilators that improve the treatment of the most critically sick Covid-19 patients.

As described in the journal Flexible and Printed Electronics [Kim et al. Flex. Print. Electron. (2021) DOI: 10.1088/2058-8585/ac1fd6], the technology, a patented, intelligent 3D-printed origami tube, looks to copy the precision folding of origami to develop 3D printable technologies for ventilators.
