3D PRINTED VENTILATOR SPLITTERS





A serious lung condition called acute respiratory distress syndrome, or ARDS, is the leading cause of death for COVID-19 patients. In individuals with ARDS, fluid builds up in the lungs, limiting the amount of oxygen in the bloodstream and depriving vital organs of the oxygen they need to function properly. The condition must be managed by a ventilator.
As the COVID-19 outbreak spreads, many health care facilities are grappling with a shortage of the machines needed to treat the sickest patients. Such shortages have already effectively crashed the health care system in Italy, which currently reports the world's highest number of COVID-19-related fatalities at more than 13,000.


Splitting ventilators is an experimental emergency treatment that has been used before under dire circumstances, such as during the aftermath of the 2017 Las Vegas shooting, when splitters were used to stabilize injured but otherwise healthy young adults. But splitting a ventilator to treat multiple patients in varying stages of lung failure presents a new and somewhat daunting set of design challenges, according to Julie Caffrey, assistant professor of plastic and reconstructive surgery at Johns Hopkins Medicine.

 "Using the same ventilator settings for ARDS patients with different lung compliances could be very unsafe. One patient might receive too much air; the other might not receive enough," Caffrey explains. "With ARDS, ventilator strategies for improving survival are often used to administer low tidal volume and higher pressure. If you can't manage that, you risk causing further trauma to lungs that are already very crippled. It's very important that when we split a ventilator, we can still set the ventilator to that specific patient."

 "The goal here is to quickly get this technology to hospitals around the world—and right to the people who need it the most," says Helen Xun, a member of the team who works on this project and a third-year medical student at the Johns Hopkins School of Medicine.

HealthyPi

By
  The HealthyPi was designed with not just one application in mind, but a variety of them. While it does function as a vital sign monitor for traditional patient monitoring applications, it can also be used for several other applications. You can use it with a Raspberry Pi using a display; use it with a Raspberry Pi with the official touchscreen using our “Complete Kit,” or you can use it standalone by connecting it to any computer’s USB port. The software is compatible across all platforms.                                                                         Resources: https://github.com/Protocentral/protocentral-healthypi-v3 http://healthypi.protocentral.com

Sterilising Lamp by Frank Chou

By
Frank Chou's Sterilising Lamp combines an ultraviolet (UV) light with a tray, and would ideally be kept by the entrance to the user's home for them to put items in such as their mobile phone, keys or wallet as they enter the room. The user would press the cover body to activate the internal UV light source, the body then lowers to cover the items in the tray with the UV light. After 60 seconds the cover automatically rises to reveal the now-sterilised items again. Frank Chou aimed to create an "unconscious design" when creating the lamp, which he hopes can blend into the home and become part of people's daily routine, as opposed to a disinfection method that they consciously have to think about doing.

Arm Door Opener for COVID-19 by CIM UPC

By
Based on the original design by Materialise, this opener, 3D-designed at CIM UPC, can be manufactured with any desktop 3D printer and simply assembled with 3 cable ties. With this opener, all shared door handles can be opened without using your hands. The engineers at CIM UPC began to analyse the different alternatives available on the market to open the doors without using the hands and realized that none were easy enough to assemble, nor did they adapt to the different types of handles and that, in general, they required special elements being difficult to procure. So they got down to work. The final outcome, after a hard week working with different designs and prototypes, is the Arm Door Opener. It consists of a single piece that can be manufactured in less than 4 hours with any desktop 3D printer and can easily be assembled with only 3 cable ties. This design has been made in two versions for doors that open to the left and to the right and the assembly is carrie...
