Housing: Plastic Display Gem Case (Circle cut out of the bottom, diaphragm attached to the outside)

Diaphragm Seal: UV Curing Glue

Visual Indicator: Circular Nail Polish on LDPE (Low Density Polyethylene; Sandwich Bag)

Membrane Seal: Generic Super Glue

Amplification: N/A

Testing Details:

(1) The visual indicator was placed on the table, with the nail polish facing into the interior of the device. The edges of the housing, which had already had the diaphragm sealed with UV curing glue, were doused in super glue. The housing was then place on top of the LDPE, made taught by a group member, where a second and third coat of glue was applied to ensure air-tightness.

(2) The visual indicator was placed on the table, with the nail polish facing into the exterior of the device. The edges of the housing, which had already had the diaphragm sealed with UV curing glue, were doused in super glue. The housing was then place on top of the LDPE, made taught by a group member, where a second and third coat of glue was applied to ensure air-tightness.

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.

(1) There was no movement that revealed clear indication of pulse.

(2) There was no movement that revealed clear indication of pulse.

 

† Not included are the initial results prior to air-tight sealing of the device. Those tests showed no membrane movement.

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