Introduction:
Statement of Purpose:
Many elderly people have trouble following complicated prescription drug regimens. These regimens can include a multitude of similarly looking pills which can cause errors and confusion. Moreover, it is imperative that medications be taken every day or when a specific condition is high (i.e. blood pressure is above a threshold). We plan to solve this by creating a health station that keeps track of vitals and if needed dispenses medication in the event of a medical emergency. Otherwise, the dispenser will dispense with a button and an ultrasonic sensor detects if a user has removed the pill.
Background research:
According to groundbreaking research in 2011 by Dr. Brown the “full benefits [of drug regimens] are often not realized because approximately 50% of patients do not take their medications as prescribed.” Additionally, some medications have requirements such as that they should be taken when a certain criterion is met. For example, some patients should only take blood pressure medication if their blood pressure is below 100 mmHg.
System Overview:
The arduino is the main controller for this project; it controls and interacts with the other components listed in the block diagram. An HC-05 Bluetooth module will be used for interaction with devices such as tablets, laptops, and cell phones. In addition to this, a pulse oximetry unit will also work with the arduino. This unit is used to measure the human pulse and the oxygen saturation in the blood. We will be using an assortment of resistors and capacitors for the purpose of signal processing. We will also be using an App which will be made via App Inventor. This app will be used by the user to interact with the health station. Finally, we will include a simple pill dispensary that can be used to deliver medicine to the user based on the readings from other components of the health station. We will also have a comparator to switch off the sensor element if battery voltage goes low,
Parts:
Stage 1: (only pulse oximetry)
MAX30100 (a pulse oximetry sensor)
Assortment of resistors and capacitors for signal processing
Arduino
HC-05
App with App Inventor
We will need to 3d print some parts for the dispensary.
Op Amp LM358 - for a battery voltage comparator circuit.
Stage 2: (if time permits, blood pressure) // This is a secondary objective that we will attempt once we complete
Honeywell Differential Transducer 015PDAA5
Air Pump
Electronically controlled valve
Challenges:
We suspect it may be hard to construct the mechanics of the pill dispensary.
Additionally, handling communication between the systems using the HC-05 may be complex.
