Housing: Plastic Display Gem Case (Pressed on diaphragm and aluminum retaining ring)

Diaphragm SealSuper Glue

Visual Indicator: Helium Balloon

Membrane Seal: Generic Super Glue

Amplification: N/A

Testing Details: In an identical manner to the initial test, the LDPE membrane was replaced with the reflective, interior of a helium balloon facing towards the user.

Results: Taken by a member of the Stony Brook Volunteer Ambulance Corp (SBVAC), which is in our group, the blood pressure procedure was standardized to the current ideal of the medical community. There was no movement that revealed clear indication of pulse.

Comments: Issues may have included no method of truly testing the seal to ensure air-tightness. 


‡ The housing top was not used in the testing of the visual indicator.
