3D-printed robot performs zero-contact COVID-19 testing

A team of engineers from the University of Southern Denmark (Odense, Denmark) has developed a 3D-printed robot for performing throat swab testing with zero human contact.

Esben Østergaard (Co-Founder of Lifeline Robotics and Universal Robots, Odense, Denmark) takes a swab in the World’s first automatic swab robot, developed with Thiusius Rajeeth Savarimuthu (Professor at the Maersk Mc-Kinney Moller Institute at The University of Southern Denmark)

The automated robot uses a 3D-printed, disposable tool to hold a swab and take a sample before placing the swab in a glass tube and fastening the lid.

“I was surprised at how softly the robot managed to land the swab at the spot in the throat where it was supposed to hit, so it was a huge success,” explained Thiusius Rajeeth Savarimuthu, Professor at Maersk Mc-Kinney Moller Institute at The University of Southern Denmark.

“There are prospects in developing a throat swab robot so that robots can take over the throat swabbing work both in relation to COVID-19, but also in all future viruses,” Savarimuthu continued.

As the message from the WHO continues to emphasize the importance of testing, the team hopes this robot could provide a solution to reduce the risk to healthcare professionals performing the tests.

“Currently, healthcare professionals are carrying out throat swabs for Covid-19; but working conditions can be a challenge. The task entails long working days of monotonous work. At the same time, the employees are in great demand in other functions,” added Kim Brixen, Medical Director from Odense University Hospital (Denmark).

“Large-scale testing is part of our community’s reopening strategy. The robot has great potential for mass screening for COVID-19 in the healthcare sector, but also in connection with border control or at airports. At the same time, we see that regular flu seems to have decreased during the lockdown. This may imply that we may need to rethink our strategy against the flu,” Brixen concluded.

Open access hardware and 3D printing could help meet the demand for medical supplies during COVID-19

In a recent study published in PLoS Biology, Scientists from the University of Sussex (UK), University of Cambridge (UK) and Francis Crick Institute (London, UK) have recommended a community approach to tackling the shortage of medical supplies.

The team recommends considering the use of free open source hardware, providing an overview of blueprints and designs currently available, focussing on PPE, ventilators and test kits.

While some designs remain to be tested, others have reportedly already met suitable verification.

Professor of Neuroscience, Tom Baden (University of Sussex), explained:

“Now is the time that Open Hardware could really shine and it’s so important that we get on board quickly. Previous studies and experiences have shown that free and open source hardware is a brilliant option in disaster situations. Designs can be shared globally, it has typically lower implementation costs than mass manufacturing and it can be easily adapted to meet local resources.”

“But the real power – and the way this could really help to tackle COVID-19 – is that once a tool has been designed and tested, anyone can build it. This bypasses the traditional manufacturing and distribution routes and means that it can become a community-driven endeavour where anyone with the capacity to do so can help to produce much-needed equipment and supplies for the healthcare services,” Baden continued.

“Anyone with the necessary knowhow, tools and time can build on this knowledge to meaningfully support their community. At a time when global health systems are facing immense pressure and becoming increasingly overburdened, we need a response not just from frontline workers such as medical staff and scientists, but from skilled members of the public who have the time, facilities and knowledge to meaningfully contribute,” Baden concluded.

ExOne and University of Pittsburgh collaboration produces reusable, metal respirator filters

ExOne (PA, USA) has announced a collaboration with the University of Pittsburgh (PA, USA) to develop reusable, metal respirator mask filters.

ExOne has reportedly 3D printed respirator filters in copper and 316L stainless steel at a range of porosity levels for use in a cartridge developed at the University of Pittsburgh’s Mechanical Engineering and Materials Science department at the Swanson School of Engineering.

Testing for airflow and filtration efficiency is now reportedly underway, as the filters are being optimized to be up to the standards of the N95 respirators.

The advantage of binder jet 3D printing over other additive manufacturing methods for this filter application is the ability to utilize the porosity of the printed part and then fine tune it during the high temperature densification or sintering process to achieve optimum filtering and airflow performance,” explained Markus Chmielus, Associate Professor of Mechanical Engineering and Materials Science at the Swanson School.

Low-cost ventilators designed for emergency use do not require electricity to function

A team from the Oregon Health and Science University (OR, USA) has developed 3D-printable, low-cost ventilators.

The design is reportedly so simple that it does not function on electricity, only oxygen from standard tanks available at most hospitals. The ventilators can be replicated worldwide for under US $10.

“The goal is to provide it for free to whoever needs it,” explained Albert Chi, an Associate Professor of Surgery (Oregon Health and Science University).

“I wanted to have something we could print everywhere without the need for special equipment or custom manufacturing,” Chi continued.

The team has filed for emergency-use authorization from the US FDA as they continue to test and refine prototypes.

Electric stockings to prevent the loss of muscle mass in hospitalized patients with coronavirus

A team of doctors and engineers has developed a biocompatible electrode which can be integrated and 3D-printed onto textiles. The team, based at Aarhus University (Denmark) hopes this technology can be adapted for use with stockings, designed to prevent the loss of muscle mass in patients with COVID-19 at intensive care units.

“One characteristic of COVID-19 patients is long-term intensive admissions and long periods on a respirator, often for up to 3 weeks. It may take months or years to recover from the treatment and some patients will never fully recover. The idea behind the project is to retain the muscle mass, so that patients are in approximately the same condition when they leave hospital as when they were admitted,” explained Charlotte Suetta (University of Copenhagen, Denmark), who is leading the clinical trials for the project at Bispebjerg Hospital and Herlev Hospital (both Denmark).

“We’re already 3D printing electrodes and wires onto the first stockings. The electrodes have three ultra-thin layers, which make it possible to stimulate the muscles through the stocking with minimal irritation. We expect to have the first 50 prototypes ready for testing by patients in a month,” added Shweta Agarwala, Assistant Professor and printed electronics specialist at the Department of Engineering at Aarhus University.

Four 3D-printed nasal swabs undergo clinical trials

Four 3D-printed nasal swabs have been identified following a clinical trial led by a multi-disciplinary team from Beth Israel Deaconess Medical Center (MA, USA).

Each swab was tested against a standard nasopharyngeal swab used to collect samples from 230 adults undergoing COVID-19 testing. According to the preprint of the team’s manuscript, the four swabs selected for review out of more than 100 designs showed excellent concordance with the standard swabs.

“To develop novel, effective alternatives as quickly and safely as possible, we and our collaborators modeled our process on scientific studies that have shown that open and collaborative processes outperform closed or proprietary ones when it comes to time-sensitive innovation,” Ramy Arnaout, Associate Director of the Clinical Microbiology Laboratories (Beth Israel Deaconess Medical Center) explained.

“We hope our collective experience can provide a useful roadmap to others working under the pressure of a public health emergency,” Arnaout added.

University of Birmingham and TU Graz announce production of medical shields for local frontline healthcare workers

A team comprised of students and staff from the University of Birmingham (UK) has 3D printed face visors for staff at Birmingham Children’s Hospital (UK).

The team aims to 3D print 60 visors in an initial batch, based on a design taken from blueprints of the tested PrusaPrinters (Prague, Czech Republic) shields previously covered in this column.

David Bassett from the School of Chemical Engineering at the University of Birmingham explained:

“Rapid prototyping offers us a route to respond directly and quickly to the shortage of PPE needed for frontline workers in the NHS and beyond. Ramping up manufacture and distribution by traditional routes takes time and these face shields will provide much needed supplementary protection for frontline workers in the fight against COVID-19 in the interim.”

Also in Europe, a collaborative team from Graz University of Technology (TU Graz; Austria) has 3D printed 1,000 protective face shields for local hospital, KAGes (Graz, Austria). The team reports that the face shields have been tested by doctors and the relevant departments from KAGes for use and hygiene, are resusable and can be easily cleaned or disinfected.

The team further reports that a total of 10,000 face shields are due to be produced for KAGes over the next few weeks.

“I am delighted that we have already been able to hand over the first 1,000 face shields to KAGes today. These were designed by my team at the Schumpeter Laboratory for Innovation at TU Graz and have been manufactured by us in shift operation since the weekend,” explained Christian Ramsauer, Head of the Institute of Innovation and Industrial Management (TU Graz).

Michigan State University, Duke University and Weil Cornell join additive response, 3D printing PPE for local healthcare workers

Michigan State University (MI, USA), Duke University (NC, USA) and Weil Cornell Medicine (NY, USA) have all announced initiatives for 3D printing protective face screens for healthcare workers in their respective areas.

Donna Crenshaw, Executive Director of Duke MEDx, the collaborative venture of the Duke School of Medicine and the Pratt School of Engineering, explained:

“It is an extra level of safety for the person who is dealing with a COVID patient or somebody who may have COVID, so it’s an extra barrier. The other thing is, it’s a mechanism for helping to preserve the really important respirators, the N95 masks, that those providers are wearing. So, it really saves them from being contaminated.”

Aaron Walworth, Laboratory Manager at the School of Packaging at Michigan State University, commented on the collaborative effort of teams at the university:

“None of us were PPE makers a few days ago and now, by pooling our talents, we’re able to do something that will hopefully make a difference. Many members of the team didn’t know each other prior to this and have still only met virtually due to social distancing. But there is this great sense of camaraderie as we’re all determined to do what we can to help.”

Kristen Petersen, Assistant Professor of Electrical and Computer Engineering at Weil Cornell Medicine concluded:

“We’re in a city of designers and my biggest job right now is trying to keep people from redesigning these parts to optimize them – people at Weill Cornell Medicine do not have the capacity right now to test out different parts. The important thing is to just keep the printers going as fast as possible: 3D printing is probably the slowest possible method of making these parts, but we don’t have anything else set up right now.”

3D-printed ventilator splitters developed at Pennsylvania College of Technology

An Associate Professor of Automated Manufacturing and Machining at Pennsylvania College of Technology has utilized his own skills, filament and 3D printer to produce eight (non-FDA approved) ventilator splitters.

“I’m trying to get ahead of the curve,” explained Eric Albert (Pennsylvania College of Technology).

“Hopefully, they won’t have to be used. If requested, I could make about 48 more in a couple days in our lab at the college. I can’t produce thousands, but I’m happy to do whatever I can,” Albert continued.

“The beauty of additive manufacturing is its flexibility. I can shift from a face shield to a ventilator splitter just by changing the computer files,” Albert concluded.

Albert has also been busy 3D printing face shields for the college’s nursing home partners.

Viscient Biosciences to bioprint lung tissue for COVID-19 research

Viscient Biosciences (CA, USA) will be utilizing 3D bioprinting technologies to develop lung tissue models for COVID-19 research.

The bioptherapeutic company hopes to be able to accelerate the testing and development of COVID-19 therapies with efficient and highly biologically-accurate results.

Keith Murphy, Founder and CEO of Viscient Biosciences explained:

“When you can remove diseased cells from the human body and reproduce that disease in a dish, you can see the true biology and quickly find a therapy that will work in clinical trials.  Drugs found in animal models so often fail because of the species gap, but as we proved with our non-alcoholic steatohepatitis liver work, important novel drug targets can be found using 3D bioprinting technology. We now are moving quickly to apply the same technology to create 3D human lung tissue to test potential COVID-19 therapies to accelerate development.”

Staff, students and faculty team up to 3D print respirators at UC San Diego

A team of engineers and physicians have rallied at University of California San Diego (UC San Diego; CA, USA) to design and 3D print simple, easy-to-use ventilators.

“One of the biggest things we heard was that there weren’t enough ventilators to treat all of the patients coming into the hospitals,” explained James Friend, Professor in the Department of Mechanical and Aerospace Engineering and the Department of Surgery at UC San Diego. “It’s clear that if we’re not careful, we might end up in the same situation.”

The team reports that the first step was to consult anesthetists and respiratory therapists about minimum requirements for a ventilator. Engineers and physicians were then able to design parts for developing their own ventilators.

“As long as the correct materials are used, 3D printing can be used to produce a wide variety of tools in the fight against COVID-19,” added Shaochen Chen, Professor of Nanoengineering at the Jacobs School of Engineering (UC San Diego). “It’s not good for, say, entire N95 masks, but it can be used for producing testing swabs or even face shields for healthcare workers.”

Lonnie Petersen, Assistant Professor in the Department of Mechanical and Aerospace Engineering at UC San Diego, explained that the team are now awaiting parts to complete a design featuring an electric pump:

“Our aim is to have functional devices as soon as possible. Once we’ve got the bare bones system up and running, we can start adding layers of sophistication and automation. Those additional layers will include advanced regulation of air pressure and flow to allow for a more disease-specific and patient-tailored respiratory support.”

The next steps will be to develop the design into a more sophisticated ventilator, potentially able to support multiple patients at any one time.

“We are preparing for a shortage of both ventilators and specialized staff to run them,” added Petersen. “The questions quickly became ‘How can we tweak the ventilators that are available to support multiple patients? How can we create more ventilators that are easier for staff to use?’”

“This is a team effort,” Petersen concluded. “And we can use the assistance of other engineers. We would love to hear from students, staff, and faculty with hands-on engineering experience who can help us with this project.”

US FDA grants emergency-use authorization for 3D-printed ventilator component

Prisma Health (SC, USA) has announced that their 3D-printed ventilator components have received US FDA authorization for emergency use.

The device, called ‘VESper™’, is described as a ‘unique’ ventilator adaptor that can allow for up to four patients to use a single ventilator. As the demand for ventilators increases as the COVID-19 pandemic develops, the splitters could be instrumental in managing a shortage of equipment.

“When we see rapid increases in patients who require machine-assisted breathing, an acute shortage of necessary equipment can happen overnight,” explained Peter Tilkemeier, Chair of the Department of Medicine at Prisma Health-Upstate.

“The VESper™ device can be lifesaving when the number of critically ill patients requiring breathing support is greater than the number of available ventilators. A number of US hospitals are likely to begin experiencing this with COVID-19,” Tilkemeier continued.

“Immediately, we realized we had an opportunity to impact patient outcomes all over the country, and potentially beyond the US,” added Marjorie Jenkins, Chief Academic Officer for Prisma Health–Upstate and dean of the University of South Carolina School of Medicine Greenville (SC, USA).

“What we needed was a collaborative team to put the plan in motion and close the loop between design, production, FDA approval and distribution to hospitals with critical need,” Jenkins continued.

3D-printed valves supply unmanageable demand for essential ventilator equipment

In one story gracing international headlines, a small team from Northern Italy has assisted health workers struggling with limited supplies of ventilator valves by quickly designing and 3D printing replacement parts.

Posting about this success on Facebook (translated from Italian), Massimo Temporelli (The FabLab; Milan, Italy) explained how supplies of the valve were depleting in a local hospital managing many COVID-19 cases, at a rate faster than what the manufacturer could feasibly supply.

Temporelli was reportedly initially contacted by a reporter, asking if it would be technically possible to 3D print the valve to keep up with the increasing demand at the local hospital.

After a few hours and many phone calls later, Cristian Fracassi of Isinonnova arrived at the hospital with a 3D printer and a design for a substitute valve, ready to print as many valves as required to meet the demand.

Since this relatively small but immediate intervention, another local additive manufacturing company, Lonati SpA, has reported that based on Fracassi’s design, team members Michele Faini and Marco Gavazzi have been able to amplify production efforts to further meet increasing demand and pressure, confirming that ‘many’ patients are now using the 3D-printed devices.

Since this story broke, there have been calls from the Government in the UK for manufacturers to switch focus on the development of more ventilators – could the 3D printing community be in a prime position to help industry deliver in the rapid production of essential medical equipment in response to the COVID-19 pandemic?

“As the UK Government calls upon engineering firms to switch some of their manufacturing output to the production of new ventilators to help tackle the coronavirus health crisis, I have brought together a consortium of industry leaders and academics from across the UK who are all looking into ways that we can support the production of parts for ventilators during these unprecedented times. 3D printing technologies can allow us to produce parts very quickly,” explained Kadine James, Creative Tech Lead at Hobs 3D (London, UK)

“We will also be hosting a Global Call with University College London (UK) on 19 March 2020,” James continued.

However, there is still some uncertainty surrounding the capability and safety of sharing STL files with hospitals and independent ‘printers’ for mass production. Outside of conflicts relating to copyright and patent law, the regulatory burden for in situ emergency 3D printing for devices use in life-critical scenarios is certainly questionable.
