ResMed Astral Double Limb Corrugated Circuit – 15 mm with Water Trap

Description

Quick answer: This is a double limb corrugated breathing circuit (15 mm, 1.6 m) with an integrated water trap for the ResMed Astral ventilator. It has separate inspiratory and expiratory limbs in flexible, kink-resistant corrugated tubing, and the water trap collects condensation that forms in the circuit so it can be drained rather than reaching the patient. The 15 mm diameter is the smaller-bore option, generally used for paediatric or lower-flow ventilation. Single-patient use. ResMed reference code: 21307.

What is a double limb corrugated circuit with a water trap?

A breathing circuit carries air between the ventilator and the patient. A double limb circuit has two separate paths — one delivering air to the patient (inspiratory) and one carrying exhaled air away (expiratory). Corrugated tubing has a ribbed wall that makes it flexible and resistant to kinking. The integrated water trap is a small collection cup that captures condensation (rainout) forming inside the circuit — especially relevant with humidified ventilation — so it can be emptied instead of pooling in the tube. The Astral supports single and double limb circuits through interchangeable circuit adapters, so this circuit is used with the double limb adapter fitted to the device.

Key features

• Integrated water trap — collects condensation for easy draining.
• Corrugated, flexible tubing — resists kinking, moves easily with the patient.
• Double limb — separate inspiratory and expiratory flow paths.
• 15 mm diameter — smaller bore for paediatric or lower-flow ventilation.
• 1.6 m length.
• Single-patient use — supports hygiene and infection control.

Specifications

Is it compatible with my ventilator?

This circuit is designed for the ResMed Astral ventilator and is used with the double limb circuit adapter fitted to the device. After assembling or changing a circuit, the Astral requires a “learn circuit” procedure. Always follow your circuit configuration and your clinician’s instructions.

Frequently asked questions

What does the water trap do?
It collects condensation (rainout) that forms inside the circuit so it can be drained, helping keep water from pooling in the tubing or reaching the patient.

What’s the difference between corrugated and smooth bore tubing?
Corrugated tubing has a ribbed wall that is flexible and resists kinking; smooth bore tubing has a smooth interior that lowers airflow resistance. Your clinician will advise which is appropriate.

What’s the difference between this and the version without a water trap?
This version (21307) includes a water trap to collect condensation; the version without one is code 21309. Your clinician will advise which is appropriate, especially when humidification is used.

Is it single-patient use?
Yes — it is intended for single-patient use to support hygiene and infection control.

Can I get it delivered in Brooklyn or shipped nationwide?
Yes — Stark Medical Supplies offers local pickup and delivery in Brooklyn and across NYC, plus FedEx shipping throughout the continental U.S.
