IMPROV ($229) is a piston type ventilator. There is an immediate need for an economical easy to assemble and modify non-FDA approved ventilator. The system specifically targets supplies and materials readily available throughout the U.S.A. The cylinder is made of 6” plastic pipe. The cap and piston can be made on FDM 3D printers readily available at maker spaces, schools, and universities throughout the nation. Hardware including electronics is based on readily available COTS parts. The powertrain system uses Vex Robotics motors, gearboxes, shafts, bearings and couplers. Vex Robotics components are used throughout the nation by middle school and high school robotics programs. These components can be substituted for other COTS components but these are widespread and available with the cancellation of the 2020 FIRST Robotics season. The inhalation/exhalation valves and mounting frame can be made via laser cutting, CNC routing, waterjet abrasive cutting, or by manual methods. Respiration volume and rate can be changed but require disassembly of the system to insert different size cams and gearboxes. With implementation of a motor controller respiration rate can be easily changed. This is a non-FDA approved untested prototype. Its safety and reliability have not been evaluated, but the hope is this system can be developed to fill the need at this time. The files and assembly instructions will be published soon.

A non-FDA approved 3D printed face shield to address the shortage of PPE. Designed for 3D printing and to print fast with no supports. Thermal shrinkage compensation to ease the assembly and alignment of parts. Currently in use at hospitals in Hawaii. Safety and protection level have not been assessed. https://www.youtube.com/watch?v=YZVbqB3YV3M This file is provided under the Creative Commons license CC BY-SA https://creativecommons.org/licenses/by-sa/4.0/

Designed to utilize available non-medical filter material to make an easy to assembly and sanitize mask. The mask can be custom heat formed using hot water. Requires half inch elastic for bands. I am currently using a combination of a MERV 12 AC furnace filter and a HEPA filter cut to 3.25" squares to make masks for my family. This appears to be the best materials I can source locally to make something with (hopefully) higher protection than a cloth mask. I decided to use both because the cost of the HEPA filter is high and in high demand. The MERV 12 material is used as a pre-filter for the HEPA filter hopefully increasing the effectiveness and life of the filter.
