Neuromuscular Stimulator TOF monitor using blocking agents
The STIMPOD NMS450 Nerve Stimulator or Neuromuscular Stimulator, has many unique features including, a Tri-axial accelerometer. This provides real time feedback of the strength of contraction of the affected limb. The Stimpod is programmable to use the following methods of stimulation: Train of four, double burst, post titanic count modes. The contraction strength of each measure, graphically displayed, provide calculated relevant ratios thus providing best practice
These fine movement differences detectable by utilizing accelerometry offer major advantages over gauging contraction strength visually or tactilely.
The NMS Stimpod 450 Tri-Axial accelerometer
Tri-axial accelerometer calculates the movement vector of the contraction in three dimensions. This negates the need for calibration as is the case with one-dimensional accelerometers. Furthermore, this reduces the setup time of the procedure.
Combined Nerve Mapping and Nerve Location
Auto sensing technology provides a solution for simultaneous nerve mapping and nerve location. The Stimpod monitors whether the mapping probe or needle touches the patient and adjusts the current range accordingly. Because of this feature, we can ensure quick and precise nerve location.
This technology provides a cost effective alternative to ultrasound techniques for determining anatomical deviations prior to needle insertion. The technique reduces the time of the procedure and provides favourable patient comfort and safety.

Nerve Mapping Techniques
Charge Transfer Waveform:
The STIMPOD displays real time graphical representation of the actual waveform delivered.
The displayed waveform serves as a quick reference for excessive impedance (> 20kOhm) in the circuit. The waveform will indicate if the pulse is delivered according to the settings. If the waveform is not square, this will immediately indicate excessive impedance in the circuit and all elements in the circuit i.e. ecg electrodes and/or skin condition, needs to be re-assessed before nerve location can be successfully completed.
The Stimpod Nerve Mapping Probe is designed to enable transcutaneous nerve mapping at higher currents (to a maximum of 20mA), whilst the tip offers a contact surface small enough ensuring effective discrimination.
Visual and audible feedback is given when the target current- and pulse width ranges are reached indicating probable nerve proximity.
The Proximity Indicator provides a safety mechanism which prevents the user from getting confused with the current settings at different pulse widths. Prior to performing your peripheral nerve block, this unique indicator will provide indication of nerve proximity.
Non-Linear Current Adjustment
In this current adjustment mode the user can pre-program 20 different current and pulse width settings.
When adjusting the adjustment wheel the STIMPOD Nerve Stimulator will only scroll through the pre-programmed Current and pulse width settings. (The default settings are calculated to facilitate the non-linear nature of the current intensity versus the distance from the nerve.)*
