Problem Statement:

Currently, MRI pumps are restricted to certain computer sequencing and to the amount of radioactive dye that can be injected. The client requires a new pump to be made that can control the infusion rates of both gadolinium and saline, without having to constantly refill the syringes. This pump must be made from non-ferrous material.

Summary of Accomplishments:

The team met to and inspected the parts purchased. The group brainstormed how to assemble the container and where to put attachments such as gas line, IV tubing, and release valve. An outline of how the prototype is to be put together was agreed upon and a decision to change the prototype container material was made. Over the break, additional parts were bought and a prototype was built. In addition, items for the poster presentation have been written and constructed.

Statement of Team Goals:

The team will begin testing finished prototype and work on completing and practicing poster presentation.

Difficulties:

A difficulty the group ran into while constructing the prototype was with the IV tubing and bag spike. Initially, the IV bag spike (plastic needle-like structure that stabs the IV bag) was supposed to be able to be pulled up from the inside to make it easer to connect the IV bag. While testing this design, the IV tubing would kink when the spike and tubing were being pulled back out through the bottom. Therefore, the bag spike was permanently placed into the bottom and is now immobile. This will make it more difficult to connect the bag to the spike

Christine Weisshaar: 3 hours, began poster presentation slides, contacted client to get more supplies

Megan Buroker: 1.5 hours, began writing for poster presentation and searched for pictures to include

Ryan Augustine: 9 hours, assembled pump and attachments

Gordy Lawrence: 1 hour, helped Ryan and Nate assemble pump
