P l e x u s   B l o c k

A dedicated nerve stimulator for plexus block, MultiStim SENSOR offers a unique and patient friendly percutaneous guidance system P E G Electrode for initial location of nerve prior to needle insertion.

f e a t u r e s :

•The actual current flowing through the patient is displayed and compared to the selected current
•Analog & digital display of stimulating current
•Dial control for setting electrical current value
•Integrated safety features
•Stimulation can be switched between cannula and percutaneous stimulating P.E.G. electrode/handle
•Highly precise, constant current is regulated by a microprocessor control system
. PAUSE FUNCTION.   By activating the pause button, stimulation may be interrupted. In Pause mode stimulation parameters may be constantly compared and displayed.
. ADJUSTABLE PULSE WIDTH.   Stimulating Pulse width is readily adjustable with a wide range of values to choose from, 0.05msec, 0.10msec, 0.20msec, 0.30msec, 0.50msec and 1.0msec .
. SETUP.   MultiSTIM Sensor is programmable via the setup button. Values for the various stimulation parameters can be stored as default settings according to the user's preferences.
. PEG or CANNULA.   With the P E G Cable attached, the PEG / CANNULA pushbutton allows you to toggle between delivering the stimulating current to the cannula or the Percutaneous electrode.


Liquid Crystal Display (LCD)
MultiStim Sensor's large and easy-to-read display details your stimulation information via numerical read-out, analogue display and simple iconography. Display elements are listed below.

(A). Maximum current available. This changes depending on which cable is attached and the function attempted.
(B).. icon appears when plexus block cable is attached and functioning.
. icon appears when PEG cable is attached and functioning.
(C). Frequency pattern, OPTIONS 1Hz or 2Hz
(D). Visual circuit indicator
. = OPEN CIRCUIT
(Check connections and viability of cable)
.Closed circle=CLOSED CIRCUIT
(E). Denotes actual current flowing through patient. This icon will disappear when unit is on PAUSE or when changes to any parameter are being made. At such time the selected current is being displayed.
(F). ( = ) The current flowing through the patient is complete, i.e. equal to the selected value.
(.) The value of the current flowing through the patient is less than that of the value selected (see G below)
(G). Analogue display of actual current flowing through the patient.
(H). When unit is on PAUSE or when changing any parameter, this is the current being delivered from the stimulator. At all other times, this is the actual current flowing through the stimulator.
(I). Battery life. Each of the 5 segments represents 20% battery life.
(J). PULSE WIDTH. Adjustable. Options are
0.05msec, 0.10msec, 0.20msec, 0.30msec, 0.50msec AND 1.0msec
