Portex® Loss of Resistance (L.O.R.) Plastic Syringe - 7mL, Luer Slip, 50/cs
The ICU Medical Portex® Loss of Resistance (L.O.R.) Plastic Syringe is a single-use, specialized device designed to facilitate the successful location of the epidural space. Engineered with a low-friction design, this syringe provides clinicians with the necessary tactile sensitivity to detect the change in pressure when entering the epidural or subarachnoid space. Its pre-lubricated construction and smooth plunger action ensure consistent and reproducible performance, supporting procedural accuracy and patient safety during regional anesthesia and pain management procedures.
Please note: All prices are for cases.
Key Features
Smooth Plunger Action: Features low-friction movement to provide the high level of sensitivity required for detecting loss of resistance.
Clear Graduated Barrel: Designed with distinct markings to allow for precise visualization and measurement of air or saline during the procedure.
Secure Luer Lock Connection: Equipped with a threaded Luer lock tip to ensure a secure, leak-free attachment to epidural needles.
Polypropylene Construction: Manufactured from durable plastic to provide a reliable and efficient alternative to traditional glass syringes.
Pre-lubricated Design: Optimized for both air and saline techniques to ensure consistent feel and performance across various clinical protocols.
Ideal Clinical Applications
Epidural Space Detection: Primarily used by anesthesiologists and pain management specialists to confirm the accurate placement of epidural catheters.
Spinal Procedures: Suitable for clinical settings where precise identification of spaces with lower resistance is vital for anesthetic administration.

Important Safety Information

This device is strictly for single-use only. Do not attempt to re-use or re-sterilize, as this increases the risk of cross-contamination and may result in mechanical failure or loss of sensitivity required for safe procedure execution. Do not use for any application other than those for which the device is specifically indicated.
Always confirm that the plunger moves freely before beginning a procedure. Visual and tactile confirmation of the loss of resistance is required for proper placement; if the plunger is retracted past the built-in stop, there is an increased risk of accidental dural puncture as the device may not function as intended. Do not use if the individual sterile packaging is damaged or opened prior to use. Always dispose of the device in an approved container immediately after use according to facility protocol.
