AN OPEN SOURCE VENTILATOR
FOR COVID-19 PATIENTS
VentCore is an open source ventilator project designed and developed by Formon in Prishtina, Kosovo.
The shortage of ventilators that the hospitals worldwide are facing has become a big issue in our fight with COVID-19. That is why we developed VentCore.
The purpose of this ventilator is automate the operation of BVM (bag-valve-mask) in a simple, inexpensive and controllable way, for emergency cases.
It is designed as an open system that can be easily produced and replicated fast, at the same time inviting everyone to contribute in its improvement as a device.
Lets not let the lack of ventilators be the reason for more deaths from this unfortunate situation we as humanity found ourselves in.

3D PRINTABLE PARTS
Most of the moving parts for the belt mechanism, and holding the BMV are 3D printable parts. In total 16 parts that you can 3D print.
SYSTEM DESIGN (updated version 1.2)
The whole mechanical system for VentCore is made of only the components shown in the exploded view.
Designing it as simple as possible was the main challenge for driving the belt to compress the BVM and to enable fast assembly. The belt mechanism contains only 6 major components:
a. A sheet metal plate – where the belt mechanism is assembled
b. 6x 3D printable parts
c. Standard size shoulder screws
d. A standard NEMA23 stepper motor (changed from NEMA17)
The bottom plate is a composite (aluminum and plastic sheet) material (in this case – Alucobond 4mm), which can be cut in a CNC machine.
The knobs for the rotary switches are 3D printable.
The Front and Back Enclosure is white acrylic sheet (5mm) that can be cut with a laser CNC machine.
The Top Enclosure is 1.5mm thick sheet metal plate.
This current version of the design contains a simple custom made electronic board, 3x rotary switches and 2x toggle switches.
All these parts can be downloaded below for more information together with BOM (Bill of Materials).
ELECTRONICS DESIGN (rev.A)
This electronic board is designed specifically for VentCore. Find the files under the Downloads and Guidelines section below.
PROTOTYPES AND TESTING (version 1.1)
5 days after the first concept, we have finally come to a fully working prototype for VentCore. Next we will start testing the usage parameters such as Tidal Volume, I:Time and Respiratory Rate together with the sensors.
