THE SMART NEEDLE
The Smart Needle is a disposable sensing needle that provides accurate, objective, and easily understandable real-time continuous monitoring of the injection pressure at the needle tip, the real pressure in the tissues, for peripheral nerve blocks.
It consists of a standard peripheral nerve block (PNB) needle, e.g. 22G x 85mm as as shown below, with an embedded fiber-optic pressure sensor that measures the injection pressure at the needle tip.

THE SMART NEEDLE MONITORING SYSTEM
The system consists of two parts: the Smart Needle (disposable sensing needle) and the Mobile Stand that carries the control unit and the visualization software.
The Smart Needle is connected to the control unit via a flexible fiber-optic cable and the visualization software allows real-time displaying and recording of the injection pressure.

FEATURES
REAL-TIME MONITORING OF THE INJECTION PRESSURE ENABLING IMMEDIATE REACTION
INJECTION PRESSURE MEASURED WHERE IT COUNTS, I.E. AT THE NEEDLE TIP = THE REAL PRESSURE IN THE TISSUES, WITH HIGH PRECISION
RELIABLE AND REPRODUCIBLE MEASUREMENT NOT AFFECTED BY THE INJECTION SYSTEM AND ITS PARAMETERS
IS USED AS A STANDARD NEEDLE FOR PERIPHERAL NERVE BLOCK
INJECTION PRESSURE PROFILE AUTOMATICALLY RECORDED
MODE OF USE IN BRIEF
- Before starting the PNB procedure, the anesthesiologist connects the Smart Needle to the control unit and starts the visualization software.
- Throughout the PNB procedure, the anesthesiologist has visual feedback of the injection pressure, which allows him/her to safely and effectively perform a perineural injection in close proximity to the nerve, injecting at low pressure and avoiding pressure spikes.
- The anesthesiologist can immediately stop the injection if there is a sudden increase in pressure, i.e. in the case of an inadvertent intraneural injection, reposition the needle and start again.
- Injection pressure profiles are automatically recorded.
