Case Study: Ensuring Dependable Power Supply for Portable Medical Ventilators
Empowering Portable Ventilators for Medical Use
A prominent manufacturer of portable ventilators collaborated with Astrodyne TDI to bring to life an innovative concept for the future of medical devices. They sought a power solution that could complement the sophisticated capabilities of their turbine-based ventilator, a compact and portable innovation that functioned without relying on external compressed gas sources. This state-of-the-art ventilator was engineered to provide a variety of ventilation modes, such as non-invasive CPAP, SIMV, Control, Assist/Control, and Apnea Backup, addressing diverse patient needs with accuracy and effectiveness.
Energy Needs for Portable Medical Ventilators
The ventilator is meticulously crafted to accommodate a wide variety of environments, ensuring its versatility and adaptability in different settings. It is designed to function seamlessly in home settings, providing essential respiratory support to patients in the comfort of their own homes. Additionally, it is equally effective in more demanding environments such as post-acute care facilities, where it can cater to the complex needs of patients recovering from serious illnesses or surgeries. This adaptability makes it an invaluable tool for healthcare providers who require a reliable and flexible solution for diverse patient care scenarios.
The ventilator is engineered to effortlessly serve both adults and children, making it a comprehensive solution for patients of all ages. This is particularly beneficial in mixed-age healthcare settings, where the ability to switch between adult and pediatric modes can save time and reduce the need for multiple devices. Equipped with a dual Lithium battery pack, the ventilator emphasizes portability and convenience, allowing healthcare professionals and caregivers to transport it easily between locations. This feature is crucial for maintaining continuous care during patient transfers or in situations where mobility is essential. The battery pack offers up to 5 hours of continuous operation on a single charge, providing ample time for treatment sessions without the need for frequent recharging. This extended battery life is particularly advantageous in emergencies or areas with limited access to power sources.
The ventilator's power specifications are robust and versatile, including an input voltage range of 80VAC to 264VAC at 47-63Hz and 400Hz, accommodating a wide range of electrical systems. This flexibility ensures that the device can be used in various regions and facilities without compatibility issues. It offers options for Class I and II inputs, providing additional safety and reliability in different electrical environments. The output voltage of 15V±5% ensures consistent and stable power delivery, which is critical for the precise operation of the ventilator's advanced features. Additionally, the ventilator features a maximum output current of 10A, which is delivered via a specialized output cord with a Lemo connector. This specialized connector ensures a secure and reliable connection, minimizing the risk of accidental disconnection during critical operations. The attention to detail in the design of the power delivery system underscores the commitment to providing a high-performance, dependable medical device that meets the rigorous demands of modern healthcare.
