T-piece injector assembly for continuous positive airway pressure

Area of Science:

• Respiratory therapy
• Medical device engineering

Background:

• T-piece systems are commonly used in respiratory support.
• Existing systems may face challenges in independently regulating continuous positive airway pressure (CPAP) and inspired oxygen concentrations.
• Maintaining stable airway pressure and oxygenation is crucial for patient outcomes.

Purpose of the Study:

• To describe a novel T-piece injector assembly for respiratory support.
• To evaluate the system's ability to deliver blended oxygen/air mixtures with independently regulated CPAP.
• To assess the system's impact on airway pressure and inspired oxygen concentrations.

Main Methods:

• A T-piece injector assembly was designed and implemented.
• The assembly delivers a blended oxygen/air mixture proximally.
• Continuous positive airway pressure (CPAP) is regulated distally via a separate injector.

Main Results:

• The system successfully delivers a blended oxygen/air mixture.
• Independent regulation of CPAP was achieved.
• The system provided different CPAP levels without significant fluctuations in airway pressure or inspired oxygen concentrations.

Conclusions:

• The novel T-piece injector assembly offers a method for respiratory support with stable CPAP and oxygen delivery.
• The system maintains the simplicity and safety of traditional T-piece setups.
• This device has the potential to improve respiratory care by providing precise control over ventilation parameters.
