Intended Use
Stimuplex HNS-12 is a peripheral nerve stimulator used to test the level of pharmacological effects of anesthetic drugs and gases to the patient and/or as a nerve locator for the verification of needle placement for the application of local anesthetics. This device can be used wherever peripheral anesthesia is normally applied (i.e. physicians office or hospital).
Device Story
Stimuplex HNS 12 is a battery-powered peripheral nerve stimulator used by physicians in hospitals or clinics for nerve localization and monitoring anesthetic drug effects. The device generates negative, current-stabilized square pulses via a stimulation cannula. The physician operates the device manually, adjusting stimulation amplitude, frequency (1 or 2 Hz), and pulse width (0.05–1.0 ms) via an adjustment knob and control buttons. An optional remote control allows for current adjustment. The device features a graphic LCD and LED status indicators. Output is delivered through a 4-pin plug connection system. By observing patient response to the electrical stimulation, the physician verifies needle placement or assesses the depth of anesthesia, facilitating safer administration of local anesthetics and monitoring of pharmacological effects.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on technological characteristics and bench testing, including physical testing and visual examination conducted according to established Quality Control Test Procedure documents.
Technological Characteristics
Battery-powered (9V alkaline) peripheral nerve stimulator. Outputs negative, current-stabilized square pulses (max 5mApp, 95 Vpp). Features graphic LCD, tricolor LED, and 4-pin electrode connection. Adjustable frequency (1/2 Hz) and pulse width (0.05-1.0 ms). Includes menu-driven interface for settings. Device is handheld, weighing 0.25 kg. Testing conforms to GMP and internal quality control procedures.
Indications for Use
Indicated for patients undergoing peripheral anesthesia procedures to test pharmacological effects of anesthetic drugs/gases and to verify needle placement for local anesthetic application. No specific contraindications.
Regulatory Classification
Identification
An electrical peripheral nerve stimulator (neuromuscular blockade monitor) is a device used to apply an electrical current to a patient to test the level of pharmacological effect of anesthetic drugs and gases.

Stimuplex® HNS 12 Trade Name:
Common Name: Battery powered peripheral Nerve Stimulator
Classification Name:
Anesthesiology Devices, Class II, 73 BXN Battery Powered Nerve Stimulator 21 CFR 868.2775
Stimuplex® HNS 11 Predicate Device: K003983
The nerve stimulator Stimuplex® HNS 12 is a battery powered peripheral nerve stimulator for localization of nerve fibers in the tissue. During the operation the operating physician holds a stimulation cannula in his right hand. Simultaneous the operation of the device happens with his left hand. The physician can hold the device with the left hand and simultaneous alter the stimulation amplitude at the amplitude controller.

The technical data of the device are:
| Battery: | 9 Volt alkaline |
|-------------------------|------------------------------------------------------------|
| Display: | 1 graphic LCD Module |
| | 1 tricolor (green, yellow, red) LED for status display |
| Operation: | 1 control button to switch on/off the device |
| | Adjustment knob to adjust the wanted stimulation current |
| | 3 control buttons to switch the stimulation parameters |
| | 4 control buttons for navigation and settings in the menus |
| | Remote control (optional stimulation current adjustment) |
| Power consumption: | 6 mA (8 mA max in warning/alarm state) |
| Stimulation current : | max. 5mApp / 0Ω - 12 kΩ |
| Stimulation voltage : | max. 95 Vpp |
| Stimulation frequency : | 1 Hz / 2 Hz |
| Flowing current | |
| measuring tolerance: | +/- 0.02 mA |
| Weight: | 0.25 kg (with battery) |
The configuration of the electrode connection is realized with a 4 pin plug connection system, which ensures correct polarity of the electrode at all times. The Stimuplex® HNS 12 generates negative, current-stabilized square pulses with selectable frequency, selectable pulse width and fine adjustable stimulation current. The pulse is shaped at both slopes by extremely fast active pulse drivers. An output amplifier specially designed for this application has an extraordinarily wide dynamic range and produces reproducible settings even below 0.1 mA. The stimulation frequency and the pulse width can be varied for different applications. The Stimuplex® HNS 12 nerve stimulator offers the facility for selecting a frequency of either 1 Hz or 2 Hz together with pulse widths of 0.1 ms, 0.3 ms or 1.0 ms. Two additional pulse widths: 0.05 ms and 0.50 ms can be enabled in options menu. Stimuplex® HNS 12 has a menu structure (in 26 languages) where the switch on parameters and options and setup parameters like tone volume, contrast, automatically switch off time, language can be configured. The battery voltage is in info menu in volt and percentage and during stimulation menu as symbol displayed.
The intended use is a peripheral nerve stimulator to test the level of pharmacological effect of anesthetic drugs and gases to the patient and/or as a nerve locator for the verification of needle placement for the application of local anesthetics. This device can be used wherever peripheral anesthesia is normally applied (i.e. physicians office or hospital). There are no known contraindications for the use of this device on any patient population.

The general technological characteristics of the Stimuplex® HNS 12 are The gonoral coormological chiars, form and intended use to the Stimuplex® HNS 11 Peripheral Nerve Stimulator. Differences between the Stimuplex® HNS 12 and the predicate device consist in the additional functions for Stimuplex® HNS and the products de measurement, electrical charge display, menu structure in 26 languages. The Stimuplex® HNS 12 is high specific for its intended use in the anaesthesiology. The differences don't affect safety and effectiveness for the intended use.
All finished products are tested and must meet all required release specifications / if firmerisans with on. The array of testing required for release include, but are not limited to: physical testing, visual examination (in process and finished product). The physical testing is defined by Quality Control Test Procedure documents. These tests are established testing procedures and parameters which conform to the product design specifications. The testing instruction records for each of the individually required procedures are approved, released, distributed and revised in accordance with document control GMP's.
