BioMedical Quadstar II Multi Modality Sequential Stimulator is a portable four channel digital NMS, INF and TENS device. It is an unique device with three waveforms, symmetric biphasic, pulsed sine and asymmetrical biphasic that can be programmed to deliver NMS, INF or TENS therapy. It has a programmable sequence which allows the user to customize the therapy and times.

Features

  • BioMedical Quadstar II  Multi Modality Sequential Stimulator Kit contents:
    - 8 pigtail electrodes
    - W
    all adaptor
  • 9 pre-programmed fixed sequences which enable the user to program 20 minutes of INF followed by 20 minutes of NMS therapy and ending with 20 minutes of TENS therapy
  • Graphic representation of the timing parameters is shown on the screen to assist the user to program the on or off ramps and on or off times
  • Patient lock system when activated prevents the patient from changing any parameters
  • When the lock is turned off, a patient compliance meter is displayed 
  • Indications:
    - Transcutaneous Electrical Nerve Stimulation (TENS)/Interefential devices are used for the symptomatic relief and management of chronic (long-term) intractable pain and as an adjunctive treatment in the management of post-surgical and post-traumatic acute pain problems
    - External electrical neuromuscular stimulation using bi-phasic output is indicated as therapeutic adjunct for prevention or retardation of muscle disuse atrophy; relaxation of muscle spasm; muscle reeducation; maintaining and increasing the range of motion; increasing local blood circulation and as an immediate post-surgical stimulation of calf muscles to prevent venous thrombosis.
  • Also available (sold separately):
    - Biomedical Lead Wires (Code L00013)
    - BioMedical BioStim PigTail Electrodes (Code EERC200M)
    - BioMedical Disposable Electrodes (Code EDRC225250)

More Information

  • Caution:
    - Federal law (USA) restricts this device to sale by or on the order of a physician so licensed by the State which he or she practices. Keep out of reach of children 
  • Contraindications:
    - TENS & EMS/NMS devices can adversely affect the operation of demand-type cardiac pacemakers. TENS & EMS/NMS is not recommended for patients with known heart disease without a physician’s evaluation of risk. Do not stimulate over the eyes or carotid sinus nerves as severe spasm of the laryngeal and/or pharyngeal muscles may occur when electrodes are placed over the neck or mouth. (These contractions may be strong enough to close the airway or cause difficulty in breathing.) Do not apply TENS & EMS/ NMS for un-diagnosed pain syndromes until etiology is established. Do not place electrodes in a manner that causes current to flow trans cerebrally (through the head). TENS & EMS/NMS devices should not be applied to malignant tumors. 
  • Warnings:
    - This device should be used only under the continued supervision of a physician, or outside the USA, by a qualified pain management specialist. TENS/Interferential stimulation is ineffective for pain of central origin (i.e. appendicitis, hepatitis). TENS/Interferential stimulation is of no curative value; it is a symptomatic treatment which suppresses pain sensation which would otherwise serve as a protective mechanism on the outcome of the clinical process. Safety of TENS/Interferential devices for use during pregnancy or delivery has not been established. For external use only. Electronic equipment such as EKG monitors and EKG alarms may not operate properly when TENS/Interferential Stimulation is in use. This device should not be used over metal implants or sleep apnea monitors.
    - Adequate precaution should be taken when treating patients with suspected heart problems or epilepsy. Caution should be exercised in the trans thoracic application of EMS devices so that the introduction of electrical current into the heart does not cause arrhythmia. The long-term effects of chronic electrical stimulation are unknown.
    - Persistent use of stimulation in the presence of skin irritation may be injurious. Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc. Simultaneous connection to RF surgery equipment can cause a burn. Operation near (e.g. 1m) short wave or micro wave therapy equipment can change the output values of the stimulator.
  • Precautions:
    - Skin irritation may occur under electrodes in isolated cases following long-term application. Consult physician if skin irritation develops. The effectiveness of TENS & EMS/NMS/Interferential Stimulation directly depends upon patient selection. Use only for the specific pain problem prescribed by the physician. Do not immerse device in water or other liquids.
    - Electrode placement and stimulation settings should be based on the guidance of the prescribing practitioner. Turn the stimulator off before applying or removing electrodes.
    - Powered TENS/EMS/NMS/Interferential devices should be used only with leads and electrodes recommended for use by the manufacturer and 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.
    - The device may be affected by electromagnetic interference. Also other electrical equipment in the close vicinity may be affected by the device. If such effects are suspected, either switch off the affected equipment and that suspected of causing the interference, or shorten connecting leads.
    - Precaution should be exercised when stimulation is used:
      1)After recent surgical procedure where muscle contraction may disrupt the healing process
      2)After an acute trauma or fracture where there is a tendency to hemorrhage
      3) Over the menstruating uterus
      4) Where the sensory nerve damage has caused the loss of normal skin sensation
  • Adverse Reactions:
    - Possible allergic reaction to tape or gel. Possible skin irritation or electrode burn under electrode. Be sure to follow the instructions of your health professional. If you do have questions or problems make sure you contact them for assistance.

ModesConstant: Use the Constant Mode or a Pulse Rate greater than 60 Hz. for the relaxation of muscle spasms only. Use of continuous stimulation and/or rates above the normal physiological range (e.g., greater than 60 Hz) could lead to rapid onset of muscle fatigue, making the device less effective in producing repeated forceful muscle contractions.

why I should use off mode with channel 1&2

If your referring the “Off TIME” when using the neuromuscular modality in the QuadStar® II, this is simply a “resting” period between contractions. The timing options make it possible for the muscle stimulator in the QuadStar® II to do a “pseudo exercise” for the weak muscle helping to reduce atrophy and reeducate.
