Control Systems for Life-Critical Devices: Precision and Safety You Can Trust

The Invisible Core of Critical Care Devices

In medical technology, the most important components are often the ones you can’t see. Behind every ventilator, infusion pump, or patient monitoring system lies a control system — the invisible intelligence that ensures devices operate safely, accurately, and consistently. 

For executives, this is both the opportunity and the risk. Control systems differentiate your product by enabling precision and responsiveness. But if they fail — even briefly — the consequences can be catastrophic for patients and devastating for your company’s reputation. That’s why control systems engineering isn’t just a technical function; it’s the foundation of trust in life-critical medical devices. 

At Boston Engineering, our Control Systems Center of Excellence (COE) specializes in designing architectures that combine accuracy, responsiveness, safety, and redundancy. By embedding control systems into the complete product development lifecycle, we help innovators deliver devices that clinicians and patients can depend on — every time.

The focus and discipline of DFX is a powerful tool if used as part of a broader strategic approach to developing product/process differentiation, and a sustainable advantage against competition. Involve Design for X in Strategy. Once your team has determined the focus of your strategy, place the focus of design on developing competitive advantage. 

At Boston Engineering, DFX is a core part of creating values during our product development process. We focus on several key DFX areas that align with our expertise:

• Design for Manufacturability (DFM)
• Design for Assembly (DFA)
• Design for Cost (DFC)
• Design for Testability (DFT)
• Design for Reliability (DFR)
• Design for Serviceability/Maintainability (DFS)
• Design for Usability (DFU)
• Design for Modularity (DFMo)

Case Example 1: Ventilator Platform Development 

During a surge in demand for critical care devices, an innovator needed to develop a next-generation ventilator platform. The system had to be reliable, precise, and capable of rapid production to meet urgent needs. 

Boston Engineering delivered by: 

• Designing closed-loop control systems to synchronize airflow with patient breathing in real time. 

• Integrating redundant sensors and fail-safes to ensure safe operation even in case of component failures. 

• Developing embedded software that performed with speed and predictability. 

• Using simulation to test performance across varied patient profiles and clinical conditions. 

Outcome: The ventilator achieved greater reliability and safety, while its scalable architecture allowed rapid production to meet emergency demand. 

Case Example 2:  Infusion Pump Control System

Another client sought to create an infusion pump capable of delivering precise micro-volumes of medication over extended periods. The challenge was ensuring accuracy under varying conditions while embedding safeguards against errors. 

Boston Engineering engineered success by: 

• Developing closed-loop control algorithms that continuously monitored and adjusted dosing. 

• Designing redundant monitoring systems to verify accuracy in real time. 

• Creating firmware and electronics architectures optimized for responsiveness and reliability. 

• Building regulatory-ready documentation to support FDA and IEC compliance. 

Outcome: The infusion pump delivered highly precise dosing with built-in safety redundancies, strengthening clinician trust and accelerating the path to approval. 

AL & ML in Health Care - The Medical Workplace Multiplier

In this new Whitepaper, learn how AI and ML can enhance the medical workforce’s abilities and improve patient outcomes. 

While some view AI as a potential job replacement threat, the reality is that these advanced capabilities are better positioned as “workforce multipliers” that will amplify the abilities of doctors, nurses, technicians and other medical professionals.

Artificial intelligence and machine learning are emerging technologies that have immense potential to reshape healthcare delivery and medical practice.

Case Example 3: Patient Monitoring Platform

A company developing a patient monitoring system needed controls that would ensure continuous, reliable performance across extended use periods. The device also had to transmit data securely while minimizing false alarms and ensuring ease of use for clinicians. 

Boston Engineering contributed by: 

• Designing embedded control systems to process sensor data in real time. 

• Implementing algorithms to filter noise and reduce false alarms. 

• Integrating secure communication protocols to protect sensitive patient information. 

• Coordinating with our Embedded Systems and Digital Solutions COEs to ensure seamless integration of hardware, software, and connectivity. 

Outcome: The platform achieved improved reliability and clinician usability, enabling continuous monitoring that enhanced patient safety and supported proactive intervention. 

The Common Thread: Control Systems + Full Development Discipline

Whether in ventilators, infusion pumps, or monitoring systems, success required more than control engineering. It required Boston Engineering’s holistic product development process: 

• Systems engineering discipline to align control systems with hardware, electronics, and human factors. 

• Risk management that identified and mitigated potential hazards early. 

• Project management expertise to deliver on time and on budget under urgent conditions. 

• Integration across COEs — Embedded Systems, Digital Solutions, and Design for X — to ensure reliability, manufacturability, and scalability. 

This integrated approach is what allowed each of these products to succeed, not just technically, but also commercially and clinically. 

Confidence in Every Critical Moment 

For medical device executives, the mandate is clear: life-critical devices must work flawlessly, every time. That’s why control systems are not just an engineering detail, but a strategic priority. 

Boston Engineering has demonstrated its ability to deliver safe, precise, and reliable control systems across ventilators, infusion pumps, and patient monitoring platforms. By combining technical depth with program management and systems discipline, we provide confidence at every stage of development. 

When you partner with Boston Engineering, you gain a team that understands what’s at stake — and delivers control systems you and clinicians can trust when it matters most.
