Respirators are a weapon to protect yourself from this war because through these the people get the oxygen they need. They are currently very expensive and it seems that 3D respiration will help all people as it is cheap and functional.
Both students are collaborating with a nursing school in order to perform the necessary tests on a man and ensure the operation of the device. It only takes three weeks for a respirator to be printed by a 3D printer. Respiratory dimensions are 210 x 180 x 220 mm and also include a 12-volt battery, making the device fully mobile for patient transport.
The students who created it said the goal is to provide the necessary assistance to hospitals, as there is a serious shortage of available medical respirators since the outbreak of the Covid-19 crisis.
"We wanted to create a large stock of breathing machines, portable and inexpensive that can be easily produced and used. From calibrators and AMBU airbags to valves, all parts can be printed from a 3D printer that uses biocompatible PLA (polylactic acid) and TPU (thermoplastic polyurethane), without the help of additional equipment. No screws are needed as the components are held in place by the clutch. The device supports a 2000 ml AMBU airbag." said Kalaitzakis.
According to Kalaitzakis and Patou, the device has the ability to control the volume of air given to the patient, as well as the number of breaths per second and the ratio of inhalation and exhalation. They say the respirator has the ability to control airflow and pressure with many other details.
