1. Sensors and Actuators

2. Feedback from DR II

This week, our group met to build the looks-like model and prepare for the Design Review II presentation. The construction process allowed us to narrow down our design ideas and have them solidified into one looks-like product that we presented in class.

1. Sensors and Actuators

This device will use a pulse oximeter, heart rate monitor, respiratory rate sensor, and a blood pressure monitor, but will have no actuators. The data collected from these sensors will instead be used with the patient’s medical history to calculate initial doses, maintenance doses, and to alarm the physician or nurse whenever a patient is in a critical state.

During Tuesday’s class, our group worked to get the display, keypad, heart rate monitor, and warning lights working. The next steps will be to create or purchase a respiratory rate sensor and to create or purchase a pulse oximeter.

2. Feedback from DR II

After our second design review presentation, we received valuable feedback from our peers and instructors. The comments were constructive and positive, but a criticism of our presentation was that the CAD component of our presentation did not add much to the understanding of our product. Instead, we should have shown drawn pictures of the device being used to more accurately convey what our product is. For our next presentation, we will be sure to only add constructive components to our presentation, instead of trying to fit something in that we believe to be required.

A concern for our project was that our device would not be able to receive the patient’s medical history. The patient’s medical history will be able to be input into the device using the keypad and arrow keys. An example of this would be if a patient has had issues with Alcohol in the past, the device will warn the nurse that the Ketamine will increase the cerebral blood flow, causing an elevation of intracranial pressure.

We are encouraged by the positive feedback we received and are looking forward for Design Review III.
