Problem Statement
Find a new design for the iris that will work with the core control.

Requirements for each element or component derived from system level goals and requirements
The requirements for the core control are having a working IRIS that can close on the users arm to create and vacuum seal.

Alternatives in design
This project was previously worked on this time its being added onto and updated.

The initial design
My design is using PVC pipe which holds an air take that pushes back against the pressured water causing to release the water until the pressure releases. The pressure valve re-closes when the pressure level goes back down. Were waiting to get a pressure valve so that we can put the piping together to test.

Experiment prototypes and tests need for design
The prototype we have now uses a user release valve in which the user determines when the pump closes for the pressure to be created.
