Attention:
In case of battery leakage, the device should not be operated anymore for safety reasons. If acid leaks
into the inside of the device, essential functional assemblies may be damaged or impaired. The device
must be returned to the manufacturer for inspection.
8 Cleaning and disinfection of the device
Only use soft, moistened cloths to clean and disinfect the device and the electrode cables. Water, soap-
suds or denaturated alcohol are particularly suitable for this purpose. Take care that no water or mois-
ture enters into the device. Alcohol, or commercially available alcohol based disinfectants containing no
methyl alcohol may be used for disinfection.
Attention:
The following agents may not be employed for cleaning purposes: trichlorethylene, acetone, butanone
(methyl ethyl ketone), benzene, methyl alcohol or cellulose thinner (Cellosolve, etc.).
9 Maintenance and technical safety checks
Check proper condition of the device and the accessories before use. A faulty device may not be oper-
ated. Electro-medical devices may only be repaired by the manufacturer or by an institution expressly
authorized by the manufacturer. A detailed description of the fault is to be included in the repair order.
9.1 Technical safety checks
Technical safety checks are not required. The functioning of the device is to be checked according to
the details given in the operating instructions before every application.
9.2 Device roster book in accordance with MPG
The operator of class IIa technical medical equipment in accordance with MPG is required to keep a
device roster book.
The following entries are to be made into the device roster book:
1. Date and time of the functionality test before the fi rst operational use of the device
2. Date and time of the familiarization, as well as the names of the persons familiarized with the opera-
tion of the device
3. Date and time of the performance of the prescribed technical safety checks (if applicable), and of
maintenance measures, as well as the name of the person or the company which has carried out the
measures
4. Date, time, type and consequences of malfunctions and repeated operating errors of the same type
The CE-conformity certifi cate is component of the device roster book.
10 Accessories and spare parts list for MultiStim
The following PAJUNK® products may be used as genuine accessories for the MultiStim devices, and
they are available in a wide variety of measurements:
• All PAJUNK® stimulation cannulae for one-time/single use nerve block anesthesia.
• All PAJUNK® stimulation cannulae for continuous nerve block anesthesia.
• Stimulatable PAJUNK® catheters for continuous peripheral nerve blocks.
• Main patient line for connecting stimulation cannulae, stimulation catheters and commercially avail-
able, CE-labeled adhesive stimulation electrodes.
• Various extensions and adapter lines.
11 Signal gradients, impulse patterns and power diagrams
For all signal gradients, stimulation is effected by means of monophase negative square pulses. Electric
energy is emitted only for the duration of the stimulation impulse. Therefore, please note, that the
comparison of nominal/effective current (indicated by »
⫽
« or »
⬆
«) is exclusively carried out during the
period in which the negative stimulation impulse is emitted. This status is saved and displayed during
the interpulse period until the next impulse is emitted.
Pulse form: square pulse
Frequency: 1 Hz or 2 Hz
Breadth according to selected output
