Smiths Medical 371821 - CIRCUIT ANESTHESIA ADULT 50.8MMDIA 60INL DUAL-LIMB GAS SAMPLING PORT/TEMPERATURE ELBOW STRAIGHT WYE BACTERIAL/VIRAL FILTER 3L BAG 10FTL MALE/MALE GAS SAMPLING LINE PORTEX LATEX DISPOSABLE (15/CS)

The Smiths Medical 371821 anesthesia circuit is a disposable adult breathing circuit designed for controlled delivery and management of respiratory gases during anesthesia procedures. It features a 50.8 mm diameter, 60-inch dual-limb configuration that provides separate inspiratory and expiratory pathways for efficient gas flow within compatible anesthesia systems.

This Portex anesthesia circuit includes a gas sampling port and temperature elbow, straight wye connector, bacterial and viral filter, 3-liter breathing bag, and a 10-foot male-to-male gas sampling line. The integrated component configuration helps streamline anesthesia workstation setup while supporting respiratory monitoring, filtration, manual ventilation, and gas sampling requirements in operating rooms and procedural care environments.

Smiths Medical 371821 circuits are supplied as disposable products in cases of 15, making them suitable for hospitals, ambulatory surgery centers, anesthesia departments, and other facilities that require standardized adult breathing circuit assemblies.

Compatibility and Applications

The Smiths Medical 371821 circuit is intended for use with compatible adult anesthesia machines, breathing systems, respiratory gas monitors, airway devices, and related anesthesia accessories. Compatibility should be confirmed with the anesthesia workstation, patient connection, monitoring equipment, and clinical protocol used by the healthcare facility.

Common applications include:

• General anesthesia procedures involving adult patients.
• Operating room ventilation and respiratory gas delivery.
• Manual ventilation using the included 3-liter breathing bag.
• Continuous or intermittent respiratory gas sampling.
• Procedures requiring access for compatible temperature-monitoring equipment.
• Hospital surgical departments and anesthesia services.
• Ambulatory surgery centers and outpatient procedural facilities.
• Specialty surgical environments where disposable dual-limb circuits are required.

The circuit should only be connected to devices and accessories with matching specifications. Clinicians must verify all connections, gas pathways, and monitoring interfaces before patient use.

Usage Guidelines

Before opening the package, inspect it for damage, moisture, punctures, or other signs that could affect product integrity. Confirm that the product reference, circuit configuration, included components, and packaging information match the intended procedure and patient requirements.

Remove the circuit using aseptic handling practices and inspect the tubing, connectors, filter, breathing bag, elbow, wye, and gas sampling line. Connect the inspiratory and expiratory limbs to the appropriate ports on the compatible anesthesia machine. Attach the patient end according to the equipment manufacturers instructions and the facilitys anesthesia protocol.

Connect the gas sampling line and any compatible temperature-monitoring equipment to the designated ports. Ensure all fittings are secure without forcing incompatible connections. Perform the required pre-use breathing system test, including leak testing, flow verification, pressure checks, obstruction assessment, and monitor calibration where applicable.

During the procedure, observe the circuit for disconnection, condensation, kinking, obstruction, excessive resistance, filter contamination, gas leakage, or abnormal breathing bag movement. Replace the circuit or affected component immediately when performance, cleanliness, or structural integrity is uncertain.

Certifications and Safety Standards

The Smiths Medical 371821 anesthesia circuit is intended for professional use in regulated healthcare environments. It should be stored, handled, connected, and disposed of according to the current manufacturer labeling, healthcare facility policies, infection-control procedures, and applicable medical device regulations.

Healthcare providers should verify the current product documentation and packaging for applicable regulatory status, material information, storage requirements, expiration details, and market-specific compliance information. Only trained anesthesia, respiratory care, or perioperative personnel should assemble and use the circuit.

The included bacterial and viral filter should be used according to its labeled specifications. Filtration performance, resistance, monitoring requirements, and replacement criteria should be evaluated as part of the complete breathing system setup.

Comparison with Competitors

Compared with basic adult anesthesia circuits that include only breathing tubing and a patient connector, the Smiths Medical 371821 provides a more comprehensive procedural configuration. Its integrated bacterial and viral filter, 3-liter breathing bag, gas sampling port, temperature elbow, and extended sampling line can reduce the number of separately packaged accessories required during setup.

The 60-inch dual-limb design offers a practical balance between circuit reach and organized positioning around the anesthesia workstation. The separate inspiratory and expiratory pathways also provide the familiar configuration commonly used with circle breathing systems.

Some competing products may require separate purchasing of the breathing bag, filtration device, gas sampling line, or monitoring elbow. The Smiths Medical 371821 combines these elements into a standardized disposable assembly, which may support faster preparation and more consistent supply management. Product selection should still be based on equipment compatibility, clinical requirements, patient needs, facility protocols, and total procedural cost.

Typical User Profile and Application Scenarios

The Smiths Medical 371821 is designed for healthcare professionals responsible for adult anesthesia delivery and respiratory monitoring. Typical users include anesthesiologists, certified registered nurse anesthetists, anesthesia assistants, operating room nurses, respiratory therapists, surgical technologists, and perioperative supply personnel.

A hospital anesthesia department may use this circuit as part of a standardized setup for scheduled adult surgical procedures. The dual-limb tubing connects to the anesthesia workstation, while the filter, breathing bag, sampling line, and monitoring ports support the clinical teams ventilation and monitoring workflow.

Ambulatory surgery centers may select this disposable configuration to simplify room preparation and support efficient turnover between procedures. Central supply and materials management departments may also benefit from the case quantity of 15 when maintaining stock for multiple operating rooms or procedural areas.

Best Practices for Use and Maintenance

• Confirm the product number and complete circuit configuration before opening the package.
• Inspect all tubing, connectors, ports, filters, and accessories for damage before use.
• Follow the anesthesia machine manufacturers instructions when connecting inspiratory and expiratory limbs.
• Perform all required pre-use leak, pressure, flow, and obstruction tests.
• Confirm that the gas sampling line is securely attached to the correct monitoring port.
• Keep tubing positioned to reduce pulling, compression, kinking, and accidental disconnection.
• Monitor the filter and breathing circuit for moisture accumulation or increased resistance.
• Use appropriate clinical judgment when managing condensation within the circuit.
• Verify that the breathing bag inflates and deflates appropriately during system testing and use.
• Do not use the circuit when packaging integrity, cleanliness, compatibility, or performance is uncertain.
• Do not clean, reprocess, or reuse a product labeled for single-patient disposable use.
• Dispose of the used circuit according to facility procedures for contaminated medical waste.
• Store unopened cases in a clean, dry area protected from excessive heat, moisture, sunlight, and physical damage.
