Intelect NMES Unit (77717) - Complete Kit

The Intelect NMES Unit (77717) is a Neuromuscular Stimulator and is used for the Prevention of Disuse Atrophy as well as Muscle Re-Education, Increasing Range of Motion and Increasing Circulation.

Long known for innovative clinical electrotherapy devices, Chattanooga Group now offers a new, portable, battery-operated Intelect® NMES device that offers fully adjustable parameters including frequency, pulse duration, three stimulation modes and timer.

Intelect NMES Unit Features:

• Knob Cover: An acrylic knob cover protects Amplitude Controls from accidental user touch when the unit is being used.
• Lid Cover: A sliding panel covers the controls for Mode, Set, INCREASE and DECREASE adjustments.
• Amplitude Controls: It controls the "INTENSITY" level of stimulating pulses. These controls located at the top of the unit regulate the amplitude, or intensity, of the stimulation and are the ON/OFF CONTROL. The ON indicator signal will stay lit as long as the unit is working, and mimics the output of the electrical pulse.
• "INCREASE" control button (triangle-button): This button increases the pulse width from 50~300μs, increases the pulse rate from 2 to 120Hz, increases Contraction ON time from 2 seconds to 99 seconds (except in Constant Mode), increases Relaxation OFF time from 2 seconds to 99 seconds (except in Constant Mode) and increases the timer from 5 to 90 min to continuous mode.
• "DECREASE" control button (inverted triangle-button): This button decreases the pulse width from 300~50μs, decreases the pulse rate from 120 to 2Hz, decreases Contraction ON time from 99 seconds to 2 seconds (except in Constant Mode), decreases Relaxation OFF time from 99 seconds to 2 seconds (except in Constant Mode) and decreases the timer from continuous mode to 90 to 5 min.
• "MODE" button (round-button on the right side of the control panel): This button selects a Stimulation-Mode. It displays the mode status from three types of function modes; which are Synchronous, Constant and Alternate.
• "SET" button (round-button on the middle of the control panel): This button sets the ramp, on time, off time, rate, width and timer. Press the 'SET' button to enter a parameter setting mode including ramp, on time, off time, rate, width and timer.
• LCD screen: This LCD displays stimulating mode, ramp, on time, off time, pulse rate, pulse width and timer. The channel output will be indicated on the left side (Channel 1) and right side (Channel 2) of the LCD screen. The modes will be displayed on the top of the LCD panel. The ramp, on time, off time, pulse rate, and pulse width will be shown on the middle-right of the screen. The timer and clock symbol display on the middle-left of the screen, the clock symbol will flash in final 5 min.
• Patient Compliance Timer: The patient compliance timer can memorize 60 sets of operation records; the total record time is 999 hours.
• Battery: 9 Volt DC Battery.
• "Low Battery " indicator: When the low power indicator flashes, the battery should be replaced with a new one as soon as possible. However, the stimulator will continue to operate for several more hours.

Intelect NMES Unit Specifications:

• Channel: Dual channels, isolated between channels
• Pulse Amplitude: 0 ~ 80 mA = 0 ~ 40 volts, adjustable (at 500 ohm load)
• Pulse Frequency (Hz): 2 ~ 120
• Pulse Width (μs): 50 ~ 300
• Contraction (On) Time (sec): 2 ~ 99, adjustable
• Relaxation (Off) Time (sec): 2 ~ 99, adjustable
• Waveform: Asymmetric biphasic square pulse.
• Timer Control (mins): 5 ~ 90 or continuous
• Stimulation Modes:
  • "S": The pulses of CHANNEL 1 and CHANNEL 2 are synchronous. While Channel 1 is activated, Channel 2 will be activated simultaneously. The pulses active and inactive duration is controlled by ON TIME and OFF TIME.
    In this mode, ON TIME value should be set for more than ramp up value plus ramp down value. For example, if you set on ramp value for 2 seconds, ON TIME should be set for more than 4 seconds (2+2), i.e. ON TIME ≥ Ramp up + Ramp down
  • "C" :Both CHANNEL 1 and CHANNEL 2 are continuous pulses under an adjustable pulse rate and pulse width. The functions of ON TIME, OFF TIME, and RAMP cannot be set.
  • "A": The pulses of CHANNEL 1 and CHANNEL 2 are Alternative. When Channel 1 is activated, Channel 2 will be inactivated and vice versa.
    In this mode, ON TIME value should be set for more than ramp up value plus ramp down value; OFF TIME value should be set for more than ON TIME value. For example, if you set on ramp value for 2 seconds, ON TIME should be set for more than 4 seconds (2+2), and OFF TIME should be set for more than 4 seconds, i.e.
    ON TIME ≥ Ramp up + Ramp down
    OFF TIME ≥ ON TIME

• Neuromuscular Stimulation is achieved by sending small electrical impulses through the skin to the underlying motor units (nerves and muscles) to create an involuntary muscle contraction.
  Neuromuscular stimulation has many uses beyond its traditional application to prevent disuse atrophy, including:
  • An increased range of motion: As a substitute for passive stretching exercise performed by the patient or therapist.
  • Muscle re-education: for example, teaching patients how to set their quads.

• Because the transdermal stimulation of nerves and muscles may be accomplished by electrical pulses, this modality can help prevent disuse atrophy. Accordingly, incapacitated patients can receive therapeutic treatment to create involuntary muscle contractions thereby improving and maintaining muscle tone without actual physical activity.

• The Neuromuscular Stimulator is an easy to use system. A marvel of miniaturized electronics, the lightweight power unit transmits electrical pulses through the skin surface and stimulates motor units (nerve and muscles). The electrical impulses are "ramped" so they closely emulate natural muscle contractions.

Cautions:

• Federal law (USA) restricts this device to sale by or on the order of practitioners licensed by the State in which they practice to use or order the use of the device.

Warnings:

• The long-term effects of chronic electrical stimulation are unknown.
• Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the carotid sinus reflex.
• Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing.
• Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause cardiac arrhythmias.
• Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc.
• Stimulation should not be applied over, or in proximity to, cancerous lesions.
• For external use only.
• Do not use NMES on the eye area.
• This device should be used only under the continued supervision of a licensed medical practitioner.
• Safety of NMES devices for use during pregnancy or delivery has not been established.
• Electronic equipment such as ECG monitors and ECG alarms may not operate properly when NMES is in use.
• Apply the electrodes to clean, dry, and unbroken skin only.
• This device should not be used while driving, operating machinery, or during any activity in which involuntary muscle contractions may put the user at undue risk of injury.
• This device should be kept out of the reach of children.
• Keep electrodes separate during treatment. Electrodes in contact with each other could result in improper stimulation or skin burns.

Precautions:

• Caution should be used for patients with suspected or diagnosed heart problems.
• Caution should be used for patients with suspected or diagnosed epilepsy.
• Caution should be used in the presence of the following:
  • (a) When there is a tendency to hemorrhage following acute trauma or fracture
  • (b) Following recent surgical procedures when muscle contraction may disrupt the healing process.
  • (c) Over the menstruating or pregnant uterus
  • (d) Over areas of the skin which lack normal sensation.
• Some patients may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical conductive medium. The irritation can usually be reduced by using an alternate conductive medium, or alternate electrode placement.
• Electrode placement and stimulation settings should be based on the guidance of the prescribing practitioner.
• This device should be used only with the leads and electrodes recommended for use by the manufacturer.
• Isolated cases of skin irritation may occur at the site of the electrode placement following long-term application.
• Effectiveness is highly dependent upon patient selection by a person qualified in the management of pain afflicted patients.
• If the stimulation levels are uncomfortable or become uncomfortable, reduce the stimulation amplitude to a comfortable level and contact your physician if problems persist.

Adverse Reactions:

• Possible skin irritation or electrode burn under the electrodes may occur.
• Possible allergic skin reaction to tape or gel may occur.
• If the stimulation levels are uncomfortable or become uncomfortable, reduce the stimulation amplitude to a comfortable level and contact your physician if problems persist.
