Smiths Medical ASD Inc NIF-TeeNon-Rebreathing T-piece, with 4 extension tube and reducer

What is SF333500-Case Smiths Medical ASD Inc NIF-Tee Non-Rebreathing T-piece, with 4 extension tube and reducer?

The SF333500-Case Smiths Medical ASD Inc NIF-Tee Non-Rebreathing T-piece is a sterile, single-patient-use airway adapter designed for non-invasive and invasive ventilation monitoring. It connects between the endotracheal (ET) tube and measurement devices like Wright respirometers or pressure gauges to assess negative inspiratory force (NIF) and spontaneous tidal volumes. Featuring a non-rebreathing valve system, it prevents exhaled gas from being re-inhaled, enhancing measurement accuracy and reducing cross-contamination risks between patients. This sterile, disposable device is commonly used in critical care, respiratory therapy, and weaning assessments.

Key features

• Crystal Clear Housing — Allows visual confirmation of airflow and valve function.
• Non-Rebreathing Valve — Prevents rebreathing of exhaled air for accurate NIF readings.
• 4" Flexible Extension Tube — Enables secure, kink-resistant connection to patient circuits.
• 22mm ID / 15mm OD Reducer — Ensures compatibility with standard ET tubes and measurement devices.
• Directional Flow Arrows — Guides proper orientation during setup to ensure correct function.
• NIF Measurement Port — Provides direct access for pressure gauge attachment during respiratory assessments.
• Single-Use Design — Reduces infection risk and ensures consistent performance.

Who is SF333500-Case Smiths Medical ASD Inc NIF-Tee Non-Rebreathing T-piece, with 4 extension tube and reducer for?

This device is intended for respiratory therapists, ICU nurses, and pulmonologists managing mechanically ventilated or weaning patients. It supports accurate assessment of respiratory muscle strength and readiness for extubation. Suitable for hospital, long-term acute care, and home care environments where precise pulmonary function data is required.

How does SF333500-Case Smiths Medical ASD Inc NIF-Tee Non-Rebreathing T-piece, with 4 extension tube and reducer compare?

Compared to standard T-pieces or reusable manometry adapters, the NIF-Tee offers superior infection control through its disposable, single-use design. Its integrated non-rebreathing valve ensures more accurate NIF measurements than open T-connectors, which allow gas mixing. Unlike generic adapters, it includes a calibrated 4" flex tube and reducer, minimizing leaks and connection issues. It outperforms basic resuscitation bags or manual techniques in reliability and clinical precision, especially in critical care evaluations.
