Smiths Medical 371033 - CIRCUIT ANESTHESIA ADULT 50.8MMDIA 40INL DUAL-LIMB GAS SAMPLING PORT ELBOW STRAIGHT WYE HME FILTER 3L BAG MASK MEDIUM ADULT PORTEX LATEX DISPOSABLE (15/CS)

The Smiths Medical 371033 anesthesia circuit is a disposable adult breathing circuit designed to support controlled delivery and management of respiratory gases during anesthesia procedures. This complete Portex configuration features a 50.8 mm diameter, 40-inch dual-limb circuit with a gas sampling port elbow, straight wye connector, HME filter, 3-liter breathing bag, and medium adult mask.

Designed for use in professional clinical environments, the circuit provides an organized, procedure-ready respiratory setup for adult anesthesia applications. Its dual-limb design separates inspiratory and expiratory gas pathways, while the included heat and moisture exchange filter helps support airway humidification and filtration during ventilation.

Key Benefits

• Dual-limb configuration provides separate inspiratory and expiratory gas pathways.
• 40-inch circuit length supports convenient positioning between the patient and anesthesia equipment.
• Gas sampling port elbow enables connection to compatible respiratory gas monitoring equipment.
• Straight wye connector supports an organized patient-side breathing circuit connection.
• HME filter helps retain heat and moisture while providing a filtration barrier within the breathing system.
• Includes a 3-liter breathing bag for manual ventilation and observation of respiratory movement.
• Medium adult mask supports routine adult anesthesia and respiratory procedures.
• Disposable configuration helps simplify infection-control protocols and turnover between patients.
• Packaged 15 circuits per case for efficient clinical inventory management.

Compatibility and Applications

The Smiths Medical 371033 adult anesthesia circuit is intended for use with compatible anesthesia machines, breathing systems, ventilators, gas monitoring equipment, and respiratory accessories that accept the circuit's specified connections. It is suitable for operating rooms, ambulatory surgery centers, hospital procedure departments, and other controlled clinical environments where adult anesthesia delivery and respiratory monitoring are required.

Typical applications may include general anesthesia, assisted ventilation, manual ventilation, respiratory gas sampling, airway humidification, and short-term breathing support during surgical or diagnostic procedures. Compatibility should always be confirmed against the anesthesia machine, patient interface, monitoring equipment, and institutional protocol before use.

Usage Guidelines

1. Inspect the packaging before opening and do not use the circuit if the package is damaged, opened, wet, or beyond its stated expiration date.
2. Confirm that the circuit configuration, length, connectors, breathing bag, mask, and HME filter are appropriate for the intended adult patient and procedure.
3. Connect the inspiratory and expiratory limbs to the corresponding ports on the compatible anesthesia machine or breathing system.
4. Attach the straight wye, HME filter, gas sampling elbow, mask, and breathing bag according to the equipment manufacturer's instructions and facility protocol.
5. Ensure every connection is secure and free from twisting, obstruction, or excessive tension.
6. Perform the required pre-use leak test, flow test, pressure check, and equipment verification before connecting the circuit to the patient.
7. Monitor airway pressure, ventilation, oxygenation, gas concentrations, circuit integrity, and patient response throughout the procedure.
8. Dispose of the circuit after use in accordance with institutional infection-control procedures and applicable waste-disposal requirements.

Certifications and Safety Standards

The Smiths Medical 371033 should be used in accordance with the product labeling, instructions for use, facility policies, and applicable regulatory requirements governing anesthesia and respiratory equipment. Healthcare facilities should verify current regulatory status, manufacturing information, and any applicable quality or safety certifications from the packaging or authorized product documentation before clinical use.

Only appropriately trained healthcare professionals should assemble, test, and operate this anesthesia circuit. Required pre-use testing should be completed before every procedure to identify leaks, loose connections, blocked tubing, damaged components, or incorrect assembly.

Comparison with Competitors

Compared with basic anesthesia circuits that require several components to be sourced separately, the Smiths Medical 371033 combines a dual-limb circuit, gas sampling port elbow, straight wye, HME filter, 3-liter bag, and medium adult mask in one disposable configuration. This can help reduce preparation time, simplify product selection, and support consistency across procedure rooms.

The 40-inch length offers a compact setup for standard adult anesthesia applications, while the integrated gas sampling connection supports respiratory monitoring. When comparing this circuit with alternatives, buyers should evaluate circuit length, limb configuration, connector compatibility, filtration requirements, mask size, breathing bag capacity, packaging quantity, and anesthesia machine specifications.

Typical User Profile and Application Scenarios

This adult anesthesia circuit is intended for anesthesiologists, certified registered nurse anesthetists, anesthesia assistants, respiratory therapists, operating room nurses, surgical technicians, and other qualified healthcare professionals responsible for respiratory equipment preparation and patient monitoring.

Common use scenarios include hospital operating rooms, outpatient surgery centers, endoscopy departments, procedural sedation areas, emergency surgical settings, and specialty clinics that perform procedures requiring adult anesthesia support. The case quantity of 15 is suitable for facilities seeking standardized disposable circuit inventory for routine procedural use.

Best Practices for Use and Maintenance

• Store unopened circuits in a clean, dry, temperature-controlled area away from direct sunlight and potential contamination.
• Rotate inventory according to expiration dates and inspect packaging during stocking and distribution.
• Verify that the circuit is intended for the correct patient population before opening the package.
• Support the tubing to prevent pulling, kinking, compression, or accidental disconnection during the procedure.
• Keep the gas sampling pathway unobstructed and confirm proper operation of connected monitoring equipment.
• Check the HME filter for increased resistance, moisture accumulation, visible contamination, or obstruction during use.
• Replace the circuit immediately if leakage, damage, blockage, contamination, or connection failure is suspected.
• Do not clean, reprocess, resterilize, or reuse a product identified by the manufacturer as disposable.

Regulatory and Safety Information

The Smiths Medical 371033 is intended for professional healthcare use under the supervision of personnel trained in anesthesia delivery, airway management, ventilation, and respiratory monitoring. Product selection must be based on the patient's clinical condition, breathing requirements, procedure type, equipment compatibility, and the judgment of the responsible clinician.

Review all warnings, precautions, contraindications, storage conditions, and disposal instructions supplied with the product before use. Do not substitute components or modify the circuit unless permitted by the relevant manufacturer instructions. Maintain continuous patient monitoring and have appropriate backup ventilation and airway-management equipment immediately available during anesthesia procedures.
