Overview of the Original Diagnosis System
TinkerCAD is an online 3D modeling software that we used to create our own rendition of the PCR machine. We used it to create a visual representation of what we had changed about the device. It helped to recreate what we retained from the original design while allowing us to add to the device.
We chose the design above so that a addition part added to the side could incorporate a fluorimeter into the PCR machine. This addition would work mechanically connecting to the rest of the PCR. This automated fluorimeter would help to eliminate human error. Additionally it would make the whole process more efficient, eliminating the need for micropipetting.
Feature 1: Consumables Kit
Liquid reagents will be stored in small tanks and containters on the exterior of the device. Rubber hosing will transport the fluids from the storage units to the needed location. This entire system is electronic and controlled by a computer chip inside the device. Small plastics will be packaged alongside the device with a means of ordering replacements made available through the internet.
Feature 2: Hardware - PCR Machine & Fluorimeter
Since both the Fluorimeter and the PCR machine are essential instruments to be used in labs for DNA related tests, any improvements to these instruments would provide for more accurate and reliable results. Regarding the Fluorimeter, the group decided to have an automated dispensing mechanism for the liquid reagents, allowing for less human errors to occur and for more accurate data. Also an improvement on the The group also considered combining these two instruments into one device to eliminate any outside contamination or other factors that could alter the results received from the lab.
