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

Diaphragm SealSuper Glue

Visual Indicator: Reflective Ribbon

Membrane Seal: Generic Super Glue

Amplification: N/A

Testing Details: In an identical manner to the initial test, the LDPE membrane was replaced with a reflective ribbon obtained by unraveling a decorative gift bow. They were cut and placed in strips across the surface to create a wide enough surface to cover the entire housing base.

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: As the gift bow had a thin fixed width, there were additional areas for air "leaking".

 

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