Updates from MSD I

Design Changes

Voltage to Amperage Converter

In order to power certain controls devices using our DAQ device, voltage outputs needed to be converted to amperage.

Safety Release Valves

Safety release valves were included in design to mitigate over pressurization risks

Confirmed end cap sealing

At the beginning of MSD II, quarter turn end caps were considered as a new design change in order to more easily seal the ends of the heart chamber. However, the team decided to stick with the threaded rods, as they also serve as a way to seal the diaphragm in place, along with sealing the end caps

New three way valve

The original three way valve for this design was donated from RIT FMS, however, the voltage requirement to power it was too high (120V). Therefore, a much more feasible three way valve was chosen. See the new three way valve spec sheet here

Confirmed & Purchased Diaphragm

Since the design change to the use of a rolling diaphragm came late in MSD I, a proper supplier was never identified & finalized until the beginning of MSD II. Previous companies had been reached out to, however, they were either unable to supply the specific design we needed, or at an affordable price range. Finally, an affordable option was purchased from Bellofram Corporation at $50 a piece.
