Your Fictional Scenario: A local hospital is experiencing a shortage of IV components.  Your engineering expertise is needed!

Objectives:

• Research and inspect online IV components. 
• CAD design.  
• Send your STL files to xyz (CC me) to remotely fabricate and the teacher remotely test an IV system component of your choice (You are welcome to do as many as you like):
• Injection Port

Constraints:

The IV Tygon Tubing dimensions:

3.5 mm inside diameter
5.75 mm outside diameter
Finished component must fit inside of this 3oz dixie bath cup: 

Criteria - Your component(s) must:

• Keep tubing joined when component is a “connector” type
• Keep liquid from passing if a “clamp” type
• If component is a stopcock type: It will be able to stop/redirect flow without leaking
• Be able to have tubing pass/hold liquid without leaking from your component

Materials

• Your parts will be 3D printed using PLA materials at 195C melting point on a 55C bed.

To submit for 3D Printing:

1. Submit a screenshot of your CAD work in Google Classroom via assignment portal
2. Email your exported STL file from your Fusion 360 to:

• xyz

CAD Tip: You may want to Construct a Plane so you can sketch cylinders that intersect with the sides of other cylinders: https://www.youtube.com/watch?v=EYbRM31EkiE

Getting results and your prototypes:

• A photo/video of your product in use will be sent to you with notes about function and form
• Your prototypes will be provided to you upon return to school
• I will save them for you

Assessment:

• This assignment is for your enrichment and a way for you to further your engineering design skills
• Successful completion will earn you an “Emergency IV Project” award
• I will put together something fun for you and provide it to you upon return to school
