We got good responses about our device after the presentation.
One of the questions is how do we ensure that all the needles are coated with the allergens. Earlier in our brainstorming sessions we were considering adding a colored dye to the allergens solvent to see the allergens on the needles. However, if the patient is allergic to dyes, all the tests would be positives and there would not be a conclusive result. We could use a fluorescent dyes when we are testing and manufacturing the needles to show that the needles are coated and determine the percentage of the needles that end up being coated.
Another concern of the project is how to determine if the patient is allergic to the allergen or not and how to view the result. The device we are designing is mostly focused on the fast administering of the allergen and not really how to read the results. For now we are considering having the doctor observe the reaction through a magnifying glass and deciding if the patient is allergic or not. However, we don't know if reducing the dosage will make the diagnosing the allergy a yes or no reaction (if there is a reaction there is an allergy vs there is no reaction therefore there isn't an allergy).
For the moment, we are waiting for the results from the survey.
