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 adult anesthesia circuit is a disposable, dual-limb breathing system designed to support controlled delivery and return of respiratory gases during adult anesthesia procedures. The circuit features a 50.8 mm diameter configuration and a 60-inch length, providing practical reach between the anesthesia workstation and the patient.

This complete Portex latex 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. Supplied 15 circuits per case, it provides healthcare facilities with a convenient procedural setup for operating rooms and other anesthesia care environments.

Key Benefits

• Dual-limb configuration supports separate inspiratory and expiratory gas pathways.
• 60-inch circuit length offers flexibility when positioning the patient and anesthesia equipment.
• Integrated gas sampling port supports connection to compatible respiratory gas monitoring systems.
• Temperature elbow accommodates compatible temperature-monitoring equipment when required.
• Included bacterial and viral filter helps support infection-control protocols and protects compatible breathing equipment from respiratory contaminants.
• Three-liter breathing bag supports manual ventilation and observation of respiratory activity.
• Ten-foot male-to-male gas sampling line provides extended reach for connection to compatible monitoring equipment.
• Disposable design supports efficient room turnover and reduces the need for circuit reprocessing.
• Complete packaged configuration helps simplify product selection and anesthesia setup preparation.
• Supplied 15 per case for convenient clinical inventory management.

Compatibility and Applications

The Smiths Medical 371821 circuit is intended for use with compatible adult anesthesia machines, ventilators, breathing-system components, gas analyzers, and patient-monitoring equipment. Connection compatibility should be confirmed before use, particularly for the gas sampling line, temperature-monitoring component, filter, breathing bag, and anesthesia workstation ports.

Typical applications include general anesthesia, intraoperative ventilation, manual ventilation, respiratory gas sampling, airway gas monitoring, and adult surgical procedures requiring a disposable dual-limb breathing circuit. It may be used in hospital operating rooms, ambulatory surgery centers, procedural suites, and other appropriately equipped anesthesia care locations.

Usage Guidelines

1. Inspect the package before use and do not use the circuit if the packaging is opened, damaged, wet, or compromised.
2. Confirm that the product reference, circuit configuration, length, included components, and patient application match the planned procedure.
3. Connect the inspiratory and expiratory limbs to the correct ports on the compatible anesthesia system.
4. Attach the straight wye and patient-side components according to the equipment manufacturer's instructions and the facility's clinical protocol.
5. Secure the bacterial and viral filter in the intended orientation and verify that all connections are properly seated.
6. Connect the 3-liter breathing bag to the appropriate system port.
7. Attach the male-to-male gas sampling line to compatible gas-sampling connections and verify unobstructed flow.
8. Connect compatible temperature-monitoring equipment to the temperature elbow when temperature monitoring is required.
9. Perform the anesthesia machine and breathing-circuit leak test required by the equipment manufacturer and facility policy before patient use.
10. Monitor circuit integrity, ventilation performance, airway pressure, gas sampling, condensation, and all patient parameters throughout the procedure.
11. Dispose of the circuit and associated single-use components after use according to applicable facility procedures and waste-management requirements.

Certifications and Safety Standards

The Smiths Medical 371821 anesthesia circuit should be used only in accordance with the manufacturer's labeling, instructions for use, applicable regulatory requirements, and institutional policies. Healthcare facilities should confirm current product documentation, market authorization, and any required standards information for their jurisdiction before clinical use.

Safe use also depends on proper anesthesia machine inspection, breathing-system testing, patient monitoring, infection-prevention practices, and adherence to established anesthesia and respiratory care protocols. Product packaging and manufacturer documentation should be reviewed for current storage conditions, expiration information, material details, warnings, and precautions.

Comparison with Competitors

Compared with basic adult anesthesia circuits that require multiple accessories to be sourced separately, the Smiths Medical 371821 provides a more comprehensive procedural configuration. Its dual-limb design, 60-inch length, gas sampling port, temperature elbow, straight wye, bacterial and viral filter, 3-liter bag, and 10-foot gas sampling line can help reduce the number of individual components needed during setup.

Alternative circuits may differ in limb length, tubing diameter, connector design, filtration, sampling-line length, breathing-bag capacity, material composition, or included monitoring ports. Product selection should be based on anesthesia workstation compatibility, patient needs, procedure requirements, facility protocols, and clinician preference rather than price alone.

Typical User Profile and Application Scenarios

This adult anesthesia circuit is designed for use by qualified anesthesia professionals and trained clinical personnel. Typical users include anesthesiologists, certified registered nurse anesthetists, anesthesia assistants, operating-room nurses, respiratory therapists, and surgical support teams.

Common application scenarios include scheduled surgical procedures, outpatient operations, general anesthesia cases requiring respiratory gas monitoring, procedures involving manual ventilation, and clinical settings where a disposable dual-limb circuit with filtration and an extended gas sampling line is preferred. It is suitable for facilities seeking a standardized adult circuit setup with multiple essential components packaged together.

Best Practices for Use and Maintenance

• Store unopened circuits in a clean, dry area within the temperature and environmental conditions specified by the manufacturer.
• Rotate inventory by expiration date and inspect packaging before transferring the product to the procedure area.
• Verify circuit compatibility with the anesthesia machine and monitoring system before opening the package.
• Support the tubing to reduce pulling, twisting, compression, or accidental disconnection.
• Keep the gas sampling line free from kinks, dependent loops, fluid accumulation, and obstruction.
• Check the bacterial and viral filter for correct placement and monitor for increased resistance or contamination.
• Manage condensation according to facility policy while maintaining the integrity of the closed breathing system.
• Repeat system checks after replacing, repositioning, or disconnecting any circuit component.
• Do not reuse or reprocess components labeled for single use.
• Document and report suspected product malfunctions through the facility's established incident-reporting process.

Regulatory and Safety Information

This product is intended for professional healthcare use in appropriately equipped clinical environments. It should be selected, assembled, tested, and monitored by personnel trained in anesthesia breathing systems and patient ventilation. The circuit does not replace continuous clinical observation or the use of appropriate oxygen, ventilation, pressure, carbon dioxide, anesthetic gas, and physiological monitoring.

Do not use the product when packaging integrity is compromised, when a component appears damaged, when a connection is incompatible, or when the circuit fails a required leak or function test. Confirm the patient's latex-related clinical history and review the manufacturer's current material information before use because this product is identified as a Portex latex configuration. Follow applicable requirements for medical-device handling, infection prevention, single-use disposal, and clinical waste management.
