LOCATION: CANADA
In the evolving landscape of medical training, where realism and precision are paramount, our client stands as a leader in simulation-based medical education (SBME). They faced a challenge: integrating a lifelike defibrillation sensor and ECG generator into their patient simulator manikin to enhance clinical competency and patient safety.
Their manikins create a realistic learning experience that fits into the modern healthcare environment and carefully replicate patient responses (such as pulse, respirations, and blood pressure (BP) and treatments (such as Cardiopulmonary resuscitation (CPR), electrocardiogram (ECG), and defibrillation). They were searching for a reliable partner with the technical acumen to accompany them in developing this pioneering product. Enter Orthogone Technologies, ready to bridge the gap between vision and reality.
Absorb and dissipate high-energy and high-voltage pulses
Measure current with a very high dynamic range
Replicate patient responses (CPR), (ECG), and defibrillation
The Solution
A partnership with Orthogone for technological expertise
Orthogone Technologies stepped up to the challenge with poise and confidence. We first analyzed the task to discover that integrating a defibrillation sensor and ECG generator into a patient simulator manikin was far from straightforward. The device needed to isolate the users from the defibrillator’s high-energy/high-voltage pulses, record the defibrillation’s shape and energy and simulate an ECG waveform on the defibrillator electrodes.
Our journey began with developing multiple design solutions for the product. We addressed high-energy dissipation, current measurement, galvanic isolation, CAN bus integration, and firmware development. We combined our extensive experience with the latest technologies to tackle these challenges. By utilizing technologies like the ST-Micro microcontroller (MCU), CAN bus, and analog to digital conversion and applying our skills in Hi-Pot testing and Underwriters’ Laboratories (UL) safety standards, we ensured that the product not only met but exceeded our client’s expectations.
