Extension shields for A.R.M.E.E emergency respirator for possible use in treatment of COVID-19 patients
ARMEE shield is a pluggable extension built on top of A.R.M.E.E pneumatic oscillator.
- Availability : Open source for everybody to reproduce and manufacture
- Therapeutic : Shield must be helpful to treat sedated COVID-19 patients in need of mechanical ventilation
- Mass production : Manufacturability in the order of thousand units and focus on different tools
- CNC
- High-pressure die casting (HPDC) mold
- SLA, SLS or Polyjet printers
- Injection molds
- Machining/milling, or any other precision forming
- FDM (Fused Deposition Modelling)
- Modularity : Pluggable hardware interfaces to support the following requirements
- Device must be easily attached / detached on top of an A.R.M.E.E pneumatic oscillator
- Other devices and accessories should be easily connected to the shield
- Interoperbility : Device should be plugged in to one of many available devices, including
- Monitors, by offering an open monitoring API and implementing popular standards
- Drives, it should be possible to connect one of multiple alternatives to air intake (at least one mechanical and pneumatic variant is compulsory)
- Standard general purpose (Prometheusi, Grafana, ...) dashboard software and medical user display/ control panels
- Customizability : Product design should adapt to alternate configurations and scenarios including
- mechanical solution should fit in the multiple usage scenarios of the device
- product should be manufactured using a variety of electronic components according to availability
- Dynamic operation mode Actuators to change oscillator parameters
- HMI to configure set point of ARMEE variables
- HMI to configure set point of other devices connected to the shield
- software must be consistent with HMI settings and must support multiple configurations
- Detachable It should be possible to detach shield for oscillator to operate in standalone manual mode
- ... which means that shield may be used as some sort of portable calibration tool
The following repositories have been added as git submodules since files needed to materialize shields.
- A.R.M.E.E v1
- Needed for oscillator shield
After cloning this project with git it is compulsory to initialize, fetch and checkout nested submodules by executing the following from the command line
git submodule update --init --recursive
This will bring all necessary files in nested submodules that might be needed to build project artifacts.
