Team Cancer Crushers
This final week Team Cancer Crushers continued working on the final prototypes, having all the CAD files for the final prototypes sorted and already 3D printed the Normal and Normal with Cysts Cervixes with Polylactic Acid (PLA) on Friday, we then proceeded with 3D Printing of the precancerous and cancerous cervixes using a flexible filament NinjaFlex.
On Monday we managed to finish printing all the stages in the development of cancer and applied the thermochromic heat sensitive paint on the precancerous and cancerous cervixes having 3 of each painted with a thermochromic paint changing color at 90°f and 1 of each with a high temperature thermochromic paint changing at 114°f . We included the two different temperature levels for color change to suit varying conditions across countries
The final design included all the improvements suggested by our client Dr Schmeler and her Lab team on the color change duration and distribution of color changing lesions on the cervixes with the aim to increase realism of the cervixes and VIA procedure. For the color change duration, we created the precancerous and cancerous cervixes with a hollow inside of which either slightly hot water will be filled to pre heat the cervix model prior to demonstrating the swabbing with acetic acid to enhance the duration or hot water will be filled into the hollow to maintain the color change of the lesions for almost 5 minutes. The color changing lesions we created them in a way that they are distributed randomly on the cervixes , not the entire surface will change color as in the medium fidelity prototypes but only on this patches like lesions. We also included the Squmocolumnar Junction on which the cancer cells develop and creating the color changing lesions around this junction.
High Fidelity Cervical Models
The final design comes with a Themos to maintain the temperature of the hot water to be used during training in order to achieve the desired color change duration that comes with high water temperatures just below the boiling temperature.
On Tuesday we started testing the Ease of Use (demonstration of the VIA procedure) and the Realistic Design Criteria with the SEED interns and the TA’s of which we obtain a score of 4.32 and 4.05 respectively on a User Defined Scale of 5 with a target score of 3.0 on each test. This completed our project tasks that we had planned to completion.
Upon completing our task, we started working on the final presentation with my team mates Karen and Mary and did the presentation on Wednesday. Was nice seeing great achievements from all the teams in their project.
On Thursday we had a client meeting with the Sonia Parra to present the final design and outline all the improvements that we implemented into the final design as suggested.
Finally, on Thursday and Friday we did documentation and clean up. We created a User Guide for the Cervical Cancer Models to be used as reference in case other teams will work on the same project and also to be used by our client in using the models.
This has been a great project, enjoyed working on it the whole time and especially being able to be successful in the project. My team members have been amazing the whole time and always focused on completing the project.
