Test Fixture

The test fixture is a model lung, which is able to accept the breath given by the ventilator. For a test fixture we need to recreate a resistive pressure as a breath is given to the mock lung and also be able to recreate an exhale as the lung returns to a relaxed state. With this mock lung, we are looking to investigate the pressure spikes seen at the ventilator due to exhalation, patient self-inspiration and compressions during CPR. These are critical elements which need to be sensed by the ventilator, so the test fixture will allow us to calibrate the sensor readings in our system's operation.

Below is a table of the material utilized to create the test fixture. In the chart below, the purpose of each item is also noted.


The completed mock lung test fixture is shown below.


This is the tubing and flow path from the pump to the test lung.


Creating the Enclosure

We are finalizing build strategy for the enclosure. In MSD I, we developed a vision for the MediResp IV Portable Emergency Ventilator. The overall aesthetic was derived from the combination of research and work from the previous revision with MSD Team 13026, and also the usability study which was completed at Imagine RIT. Now moving forward, we need to finalize the build strategy for bringing this vision to life.

Below outlines our options to developing a enclosure.


Finalizing on thermal molding the enclosure by hand has allowed us to move forward with the detailing the build plan.

The strategy is to create a 1:1 mock model out of Cardboard. This is to

1. Practice on a much less expensive and permanent material

2. Understand the outline template required of panels to meet shape

3.Create a mock visual before moving forward with plastic
