METHOD AND APPARATUS TO DECREASE THE RISK OF INTRANEURONAL INJECTION DURING ADMINISTRATION OF NERVE BLOCK ANESTHESIA

摘要

An objective and reproducible system for, and method of, monitoring and/or controlling the pressure during nerve blockage injection, especially by less experienced personnel, is provided in order to decrease the possibility of intraneuronal injection. More specifically, the present invention employs a pressure sensing and/or limiting device (20) located between an injection device (10) (typically a syringe) and a nerve block needle (60) whereby injection pressure during a nerve block injection can be easily and objectively monitored, thereby allowing the operator to monitor the injection pressure and/or linjection speed during a nerve blockage injection procedure and to take appropriate corrective actions if abnormal pressure conditions are observed.
