Smiths Medical 371804 - CIRCUIT ANESTHESIA ADULT 50.8MMDIA 60INL DUAL-LIMB GAS SAMPLING PORT ELBOW STRAIGHT WYE BACTERIAL/VIRAL FILTER 3L BAG PORTEX LATEX DISPOSABLE (15/CS)

The Smiths Medical 371804 anesthesia circuit is a disposable adult breathing circuit designed to support the controlled delivery and return of respiratory gases during anesthesia procedures. This 50.8 mm diameter, 60-inch dual-limb circuit provides separate inspiratory and expiratory pathways for efficient gas management in operating rooms and procedural care environments.

The complete configuration includes a gas sampling port elbow, straight wye connector, bacterial and viral filter, and 3-liter breathing bag. Its integrated components help simplify anesthesia workstation setup while supporting respiratory monitoring, manual ventilation, and infection-control practices. The Smiths Medical 371804 circuit is supplied in a case of 15 disposable units.

• Packaged 15 circuits per case for convenient institutional inventory management.

Compatibility and Applications

The Smiths Medical 371804 adult anesthesia circuit is intended for use with compatible anesthesia machines, breathing systems, respiratory gas monitors, and ventilation equipment that accept the supplied connectors and circuit dimensions. It is suitable for general operating rooms, ambulatory surgery centers, hospital procedure departments, and other clinical settings where anesthesia gases are administered to adult patients.

Typical applications include general anesthesia, assisted ventilation, controlled ventilation, manual ventilation, respiratory gas sampling, and patient monitoring during surgical or diagnostic procedures. Compatibility with specific equipment should be confirmed by reviewing the anesthesia machine specifications and the product instructions before use.

Usage Guidelines

Inspect the package before opening and do not use the circuit if the packaging is damaged, opened, or compromised. Remove the circuit using aseptic handling practices and visually examine the tubing, connectors, filter, elbow, wye, sampling port, and breathing bag for damage or obstruction.

Connect the inspiratory and expiratory limbs to the appropriate ports on the compatible anesthesia machine. Attach the straight wye and gas sampling port elbow at the patient end as required by the clinical setup. Secure the bacterial and viral filter and connect the 3-liter breathing bag according to the equipment configuration and facility protocol.

Before patient connection, perform the anesthesia machine and breathing circuit checks required by the equipment manufacturer and healthcare facility. Confirm that all connections are secure, the circuit is unobstructed, the breathing bag functions correctly, and no leaks are present. Use the circuit only under the supervision of qualified healthcare professionals.

Certifications and Safety Standards

The Smiths Medical 371804 anesthesia circuit should be used in accordance with the manufacturers instructions, applicable healthcare regulations, institutional infection-control procedures, and anesthesia equipment safety requirements. Product labeling and packaging should be reviewed for current regulatory information, storage requirements, lot identification, expiration details, and any applicable compliance markings.

Clinical staff should follow established standards for anesthesia breathing systems, respiratory monitoring, equipment testing, patient observation, and disposal of used medical devices. The circuit should not be used when its condition, packaging integrity, or compatibility cannot be confirmed.

Comparison with Competitors

Unlike basic anesthesia circuits that require several components to be sourced separately, the Smiths Medical 371804 combines a dual-limb adult circuit with a gas sampling port elbow, straight wye, bacterial and viral filter, and 3-liter breathing bag. This integrated configuration can reduce preparation time and help standardize anesthesia workstation setups.

The 60-inch length provides additional positioning flexibility compared with shorter breathing circuits, while the dual-limb configuration maintains distinct inspiratory and expiratory gas pathways. The inclusion of respiratory monitoring and filtration components makes this model a practical option for facilities seeking a complete disposable anesthesia circuit from an established medical device manufacturer.

Typical User Profile and Application Scenarios

This anesthesia circuit is designed for use by anesthesiologists, certified registered nurse anesthetists, anesthesia assistants, operating room nurses, respiratory therapists, and other trained clinical professionals. It is appropriate for hospitals, outpatient surgery centers, specialty surgical facilities, emergency procedure areas, and procedural sedation departments.

The Smiths Medical 371804 may be selected for routine adult surgical cases requiring a dual-limb breathing system, manual ventilation capability, gas sampling access, and bacterial and viral filtration. It is particularly useful for facilities that prefer preconfigured disposable circuits to support consistent setup procedures and efficient room turnover.

Best Practices for Use and Maintenance

• Store unopened circuits in a clean, dry environment within the temperature and humidity limits stated on the packaging.
• Keep the product in its original packaging until it is required for a procedure.
• Verify the product reference number, configuration, package integrity, and expiration information before use.
• Check every connection carefully to prevent accidental disconnection or respiratory gas leakage.
• Position the tubing to minimize pulling, twisting, compression, kinking, and excess weight near the patient airway.
• Confirm that the gas sampling line and port remain unobstructed throughout the procedure.
• Monitor the bacterial and viral filter for moisture accumulation, contamination, blockage, or increased breathing resistance.
• Observe the breathing bag and circuit continuously for changes that may indicate a leak, obstruction, or equipment issue.
• Do not attempt to clean, disinfect, resterilize, or reuse a disposable circuit.
• Dispose of the complete used circuit according to facility policy and applicable medical waste regulations.

Regulatory and Safety Information

The Smiths Medical 371804 is a disposable medical breathing circuit intended for professional clinical use. It should be selected, assembled, tested, and monitored only by personnel trained in anesthesia delivery systems and airway management. This product is not intended for unsupervised home use.

Confirm patient suitability, equipment compatibility, and correct circuit orientation before beginning anesthesia. Improper assembly, loose connections, blocked tubing, excessive condensation, filter obstruction, or circuit damage may interfere with ventilation and gas delivery. Maintain continuous patient monitoring and replace the circuit immediately if performance or integrity becomes uncertain.

Do not reuse the circuit between patients. Reuse or reprocessing of a disposable breathing circuit may lead to contamination, material degradation, connection failure, inaccurate monitoring, or increased infection risk. Always follow the current manufacturer instructions supplied with the product.
