Smiths Medical 374000 - CIRCUIT ANESTHESIA ADULT 50.8MMDIA 40INL DUAL-LIMB GAS SAMPLING PORT SWIVEL WYE 3L BAG PORTEX LATEX DISPOSABLE (20/CS)

The Smiths Medical 374000 anesthesia circuit is a disposable adult breathing circuit designed for use during anesthesia administration and other controlled respiratory procedures. It features a 50.8 mm diameter, 40-inch dual-limb configuration that provides separate inspiratory and expiratory pathways for efficient gas delivery and return.

This Portex anesthesia circuit includes a gas sampling port, swivel wye connector, and 3-liter breathing bag. The swivel wye supports flexible positioning near the patient connection, while the gas sampling port enables integration with compatible monitoring equipment. Supplied as 20 circuits per case, the Smiths Medical 374000 is intended for professional use in operating rooms, surgical centers, and other anesthesia care environments.

Key Benefits

• Adult dual-limb configuration provides separate inspiratory and expiratory gas pathways.
• 40-inch circuit length supports practical positioning between the patient and anesthesia workstation.
• 50.8 mm circuit diameter is designed for adult anesthesia applications.
• Integrated gas sampling port supports connection to compatible respiratory gas monitoring systems.
• Swivel wye allows the patient connection to move more freely during positioning and procedural adjustments.
• Included 3-liter breathing bag supports manual ventilation, gas reservoir management, and breathing system observation.
• Disposable construction helps reduce cleaning requirements and the risk of cross-contamination between patients.
• Case packaging of 20 circuits supports inventory management in high-volume clinical environments.

Compatibility and Applications

The Smiths Medical 374000 circuit is intended for use with compatible anesthesia machines, ventilators, respiratory monitoring equipment, airway devices, and patient connection accessories. Before use, clinicians should confirm that all connectors, monitoring lines, filters, masks, endotracheal tubes, and related components are suitable for the selected anesthesia system.

Common applications include general anesthesia, assisted ventilation, controlled ventilation, manual ventilation, perioperative respiratory support, and procedural sedation where an adult dual-limb breathing circuit is required. The circuit may be used in hospital operating rooms, ambulatory surgery centers, specialty procedure rooms, and other appropriately equipped clinical settings.

Usage Guidelines

1. Inspect the packaging before use and do not use the circuit if the package is opened, damaged, contaminated, or past its stated expiration date.
2. Remove the circuit using appropriate infection-control practices.
3. Connect the inspiratory and expiratory limbs to the corresponding ports on the compatible anesthesia machine or breathing system.
4. Attach the swivel wye to the appropriate patient airway interface, filter, mask, or endotracheal tube as required by the procedure.
5. Connect the gas sampling port to compatible monitoring equipment when respiratory gas analysis is required.
6. Attach and position the 3-liter breathing bag according to the anesthesia machine configuration and facility protocol.
7. Perform the required breathing system leak test, pressure test, flow test, and equipment checkout before connecting the circuit to the patient.
8. Monitor circuit integrity, airway pressure, gas flow, ventilation parameters, and patient condition throughout the procedure.
9. Dispose of the circuit after use according to applicable facility procedures and local medical waste requirements.

Certifications and Safety Standards

The Smiths Medical 374000 anesthesia circuit is intended for professional healthcare use and should be handled in accordance with the manufacturers instructions, institutional anesthesia protocols, infection-control procedures, and applicable medical device regulations. Healthcare facilities should verify current product labeling, regulatory status, and compliance documentation for their jurisdiction before purchasing or placing the device into service.

All connections should be checked for security, compatibility, obstruction, leakage, and correct orientation before patient use. The anesthesia machine and associated monitoring equipment should undergo the required pre-use inspection and functional testing established by the manufacturer and the healthcare facility.

Comparison with Competitors

Compared with basic adult anesthesia circuits that require multiple separately sourced accessories, the Smiths Medical 374000 combines a dual-limb breathing circuit, gas sampling port, swivel wye, and 3-liter bag in one disposable configuration. This integrated arrangement can simplify preparation and help reduce the number of individual components required during setup.

The swivel wye distinguishes this model from circuits equipped with a fixed patient connector by allowing additional movement at the patient end. The 40-inch length may also be preferable in clinical settings where a relatively compact connection between the anesthesia workstation and patient is required. Product selection should remain based on equipment compatibility, clinical procedure, patient requirements, facility policy, and clinician preference.

Typical User Profile and Application Scenarios

The Smiths Medical 374000 is intended for use by anesthesiologists, certified registered nurse anesthetists, anesthesia assistants, respiratory therapists, operating room nurses, and other qualified healthcare professionals trained in anesthesia breathing systems and respiratory monitoring.

Typical application scenarios include routine adult surgical procedures, general anesthesia cases, ambulatory procedures, diagnostic interventions requiring controlled ventilation, and operating room setups where gas sampling and flexible patient-end positioning are needed. The 20-count case configuration is suitable for hospitals, surgery centers, anesthesia departments, and medical supply facilities that maintain disposable breathing circuit inventory.

Best Practices for Use and Maintenance

• Store unopened circuits in a clean, dry, temperature-controlled area away from direct sunlight, excessive heat, moisture, chemicals, and physical damage.
• Rotate inventory by expiration date to support appropriate stock management.
• Keep the circuit sealed until it is required for patient care.
• Confirm that the inspiratory and expiratory limbs are connected to the correct machine ports.
• Check the full circuit length for twisting, compression, disconnection, puncture, or obstruction.
• Position the swivel wye and tubing to minimize unnecessary pulling on the patient airway device.
• Secure the gas sampling connection and verify that the sampling line does not interfere with ventilation.
• Complete all required machine and circuit tests before use.
• Do not attempt to clean, disinfect, reprocess, or resterilize a disposable circuit for reuse.
• Replace the circuit immediately if damage, contamination, leakage, blockage, or functional irregularity is identified.

Regulatory and Safety Information

This device should be selected, assembled, tested, and used only by trained healthcare professionals. Improper connection, circuit obstruction, leakage, accidental disconnection, or incompatible components may compromise ventilation and anesthesia delivery. Continuous patient monitoring and immediate access to alternative ventilation equipment are essential during use.

The product description identifies this circuit as containing latex. Healthcare professionals should review the current package labeling and manufacturer documentation before use, particularly when treating patients or staff members with known or suspected latex sensitivity. Do not use the device when latex exposure is contraindicated.

Follow the manufacturers instructions for use, the anesthesia machine operating manual, facility infection-control policies, and all applicable local regulations. Product specifications, packaging, and regulatory information should be confirmed before ordering because manufacturer details may change.
