Smart Medical Devices: Software Architecture, Features, Tech Stack
With 17 years of experience in healthcare software development and 11 years in IoT, ScienceSoft is fully equipped to advise on and implement IoT-based medical device software.
The Essence of Smart Medical Devices
Both wearable and non-wearable, smart medical devices are efficiently used for remote patient monitoring, care delivery, diagnosing, and more. IoT-based systems powering medical devices automate routine tasks like vitals collection, predict disease risks and disease flow, and improve efficiency of medical staff.
The global smart medical devices market is expected to amount to $23.5 billion by 2027 at a CAGR of 23.5%. In 2021, this technology was adopted by 25% of US broadband households. The popularity of smart medical devices is based on the need to closely check such chronic diseases as diabetes, asthma, COPD, etc., and limited access to on-site medical monitoring due to the COVID-19 pandemic.
How IoT Software for Smart Medical Devices Works
- Smart medical devices (e.g., ECG monitors, spirometers) – to collect patient data or deliver therapy; equipped with connectivity capabilities (e.g., via Wi-Fi, NFC) and actuators to trigger a set of pre-programmed actions (e.g., for insulin pumps to adjust insulin dosage).
- Gateways – to filter, preprocess, and transfer data from the patients’ devices to the cloud, transmit control commands to the smart medical devices, etc.
- Cloud gateway – to compress data from smart medical devices and transmit it from gateways and the cloud IoT server in a secure and efficient way.
- Streaming data processor – to transmit the input data from smart medical devices to the data lake and control apps.
- Data lake – to store PHI data collected by smart medical devices in its natural format.
- Big data warehouse – to store structured data for further analysis of patient progress, symptoms, etc.
- Data analytics – in-depth analysis of collected patient health parameters or therapy device use patterns to spot trends and produce insights for further diagnosing, treatment or lifestyle adjustments, etc.
- Machine learning module and ML models – to recognize certain patterns in patient symptoms or vitals and create a model for a control application to improve patient care precision and efficiency (e.g., to improve heart failure therapy delivered by implantable cardiac defibrillator).
- Control application – to send commands to actuators installed in smart medical devices to trigger device actions.
- Software business logic – to provide medical device monitoring data to patients and doctors, record new device configurations, etc.
- Medical staff interface – to enable nurses, doctors, etc., to access the patient health monitoring data, get alerts on critical changes in it, configure threshold vitals parameters for alerts, adjust dosages of medications, view the insights on patient health state based on smart device data analysis, etc.
- Patient interface – to allow patients to view their health parameters (e.g., heart rate, glucose levels) and the state of a connected device via a mobile app, get alerts on suspicious health parameters, etc.
- Admin interface – to view the list of current software users (patients and medical staff), manage access to the system, etc.
- EHR integration – for an integrated view of patients’ medical history (chronic conditions, allergies, etc.), etc.
Medical staff can monitor the vitals of patients with chronic medical conditions (e.g., COPD, diabetes, cardiovascular diseases) provided by smart medical devices to spot slow or abrupt changes in the health state and adjust treatment routines.
Remote care delivery
Patients can get therapy using smart therapeutic devices (e.g., insulin pens, smart inhalers, smart gloves for motor functions rehabilitation). The medical staff gets data on therapeutic device use (e.g., asthma treatment delivery, insulin injection), metrics on patient performance during physical therapy sessions, the patient recovery process, etc.
Based on the analysis of continuously collected patient health data (e.g., heart rate, blood pressure), doctors can make informed decisions on patient diagnosis and further treatment, assess risks of disease progression, etc.
Medication plan adherence monitoring
With data from devices like smart pill bottles or smart insulin pens, doctors can remotely track patients’ medication intake (the dosage, the missed medications, etc.), check the medication adherence and efficiency, tune recommended dosage. Patients can also get automated notifications to take medications in time.
Paramedics patient monitoring
When the ambulance is delivering a patient to the hospital, wireless patient monitoring solutions allow doctors in the hospital to track a patient’s condition in real time and plan the patient care (including emergency surgeries).
During the training, athletes can use wearable medical devices (e.g., heart monitors) for sports physicians to get a real-time health state and health risks assessment, an athlete’s performance data, and issue recommendations on the training plan.
Real-time patient health data tracking and analytics
Patient health data from connected medical devices is automatically stored, processed and analyzed in real time using AI to identify trends and predict the course of the disease, detect hazardous symptoms at an early stage, etc. The generated insights are presented in dashboards and reports for the medical staff to track patients’ health state improvements, diagnose patients, adjust the treatment, medication efficiency or plan additional screenings.
Automated treatment delivery
Smart therapeutic devices (like an insulin pump) can automatically deliver treatment or indicate that treatment is needed (e.g., using a sound signal) if the IoT system identifies the need for treatment (e.g., if a connected glucose monitor shows a high level of blood glucose). Based on the collected diagnostic and historical data, the necessary medication dosage can be calculated.
Medication intake tracking
Analysis of medication intake data automatically uploaded from connected medical devices (e.g., insulin pump) and vitals from diagnostic medical devices provide insights on patient adherence to a treatment plan, medication dosage efficiency, etc.
Alerts to patients and doctors
The patients and doctors are automatically alerted when health parameters collected by medical devices are lower or higher than the set threshold parameters (indicating a potentially unsafe condition for a patient). The system also sends alerts on missed medication.
Configuration of monitoring and treatment delivery parameters
Using historical data on a patient’s health state and medical history, a doctor can configure monitoring parameters of smart medical devices to tune them to a specific patient and their medical condition. ML algorithms identify patterns in the patient’s health state, which can trigger automated adjustment of the treatment delivery.
