This Bain circuit is a coaxial Mapleson D breathing system incorporating an adjustable pressure limiting (APL) valve. Fresh gas is delivered to the patient through the inner tube, while exhaled gas returns through the outer tube to the reservoir bag and APL valve at the machine end. The coaxial design means only one lightweight tube runs to the patient, reducing drag on the airway and keeping the working area clear.
Key Features:
Coaxial Mapleson D breathing system with integrated APL valve
Inner tube delivers fresh gas to the patient, outer tube returns exhaled gas
Single lightweight tube to the patient reduces drag on the airway
Adjustable pressure limiting valve for controlled ventilation and spontaneous breathing
Available in adult and pediatric versions
Single-use, individually packed
Applications:
Anesthesia breathing systems for spontaneously breathing patients
Controlled ventilation with a Mapleson D coaxial system
Operating theatre anesthesia where a lightweight circuit is preferred
Procedures requiring a low-clutter circuit configuration
Important Notes:
Single use only. Do not reuse or resterilize.
Do not use if the package is damaged or opened.
Check the patency of the inner tube before use. A blocked or kinked inner tube will prevent fresh gas from reaching the patient.
Do not kink or compress the coaxial tube during use.
Check that the APL valve and all connections are correctly set before starting anesthesia.
Fresh gas flow requirements for a Mapleson D system differ from circle systems; follow your institution's protocol.
This product is a breathing system. It does not provide ventilatory support on its own.
