Abstract:Extracorporeal Membrane Oxygenation (ECMO) is a temporary lifesaving treatment for critically ill patients suffering from severe respiratory and/or cardiac failure. Studies have demonstrated the feasibility of mobilization in ECMO patients within the hospital during their bridge to recovery or transplantation. Ambulatory ECMO is a comprehensive form of mobilization aimed at preventing neuromuscular weakness and impaired physical functioning during and after treatment. Despite more compact and mobile ECMO devices, the implementation of ambulatory ECMO remains a labour-intensive, complex, and challenging operation. Ambulatory ECMO requires a large multidisciplinary team to carry all the equipment, to monitor and physically support the patient, and to provide a back-up wheelchair in case of patient fatigue. Additionally, current configuration of devices contributes to unnecessary device transport. Moreover, there is no adequate solution for ensuring the stability of the patient's cannula and circuit management during ambulation. We designed and developed a system that contributes to the improvement and innovation of current ambulatory ECMO patient programs. The modular cart-in-cart system carries the necessary ECMO equipment, features an extendable walking frame, and contains a folding seat for patient transport. A universal-sized shoulder brace with integrated blood tubing connector facilitates secure fixation of the blood tubing. This system provides safety, support and accessibility while performing ambulatory ECMO for both patient and healthcare provider. Evaluation of the prototype in a simulated ICU environment shows the suitability for use in a clinical setting. The patent for this invention has been filed and is currently pending.
