NERVE STIMULATOR (Stimuplex HNS12)

Definition

The electrical stimulation of peripheral nerves facilitates the atraumatic performance of regional anaesthesia blocks.

This technique allows the localisation of nerve plexuses and peripheral nerves with a motor component. During injection of local anaesthetics, the immediate simultaneous disappearance of the motor response helps to confirm the right position of the needle.

The nerve stimulator is used by anaesthetists.

Specifications

Precautions for Use

  • The nerve stimulator is intended only for the pre-operative localization of nerves; under no circumstances may it be used on a patient undergoing surgery.
  • The nerve stimulator should not be used on patients with implanted electrical devices (e.g. cardiac pacemakers) without prior consultation with an appropriate medical specialist.
  • To avoid damage to the connecting cable and the device, do not hold or carry the device by its connecting cables and/or its accessories. Do not wrap the cable around the device or around other equipment.
  • Under no circumstance should the device be operated with accessories other than those released and supplied by the manufacturer or listed in the user's manual.

Maintenance

Cleaning and disinfection of the generator:

  • Use a detergent/disinfectant for surfaces/non-invasive medical equipment. Prepare use-solution in concentration required. Always read the label and product information before use. Do not mix with other products.
  • Make sure to wet the surfaces completely, use a wipe or towel, keep them wet for the whole exposure time.
  • Do not dry in sunlight.
