1. SAFETY INFORMATION 1.1 General InTENSityTM 10 TENS stimulator is a portable electrotherapy device featuring Transcutaneous Electrical Nerve Stimulation (TENS) therapeutic device, which is used for pain relief. The stimulator sends a gentle electrical current to underlying nerves and muscle group via electrodes applied on the skin. The parameters of device are controlled by the buttons. Its intensity level is adjustable according to the needs of patients. 1.2 Medical background EXPLANATION OF PAIN Pain is a warning system and the body's method of telling us that something is wrong. Pain is important; without it abnormal conditions may go undetected, causing damage or injury to vital parts of our bodies. Even though pain is a necessary warning signal of trauma or malfunction in the body, nature may have gone too far in its design. Aside from its value in diagnosis, long-lasting persistent pain serves no useful purpose. Pain does not begin until coded message travels to the brain where it is decoded, analyzed, and then reacted to. The pain message travels from the injured area along the small nerves leading to the spinal cord. Here the message is switched to different nerves that travel up the spinal cord to the brain. The pain message is then interpreted, referred back and the pain is felt. EXPLANATION OF TENS Transcutaneous Electrical Nerve Stimulation (TENS) is a noninvasive, drug free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not cure any physiological problem; it only helps control the pain. TENS does not work for everyone;
4
however, in most patients it is effective in reducing or eliminating the pain, allowing for a return to normal activity. HOW TENS WORKS There is nothing "magic" about Transcutaneous Electrical Nerve Stimulations (TENS). TENS is intended to be used to relieve pain. The TENS unit sends comfortable impulses through the skin that stimulate the nerve (or nerves) in the treatment area. In many cases, this stimulation will greatly reduce or eliminate the pain sensation the patient feels. Pain relief varies by individual patients, mode selected for therapy, and the type of pain. In many patients, the reduction or elimination of pain lasts longer than the actual period of stimulation (sometimes as much as three to four times longer). In others, pain is only modified while stimulation actually occurs. You may discuss this with your physician or therapist. 1.3 Indication for use InTENSityTM 10 TENS Stimulator should be used for the Symptomatic relief of chronic intractable pain, acute post traumatic pain, acute post surgical pain and arthritis pain. MPORTANT SAFETY INFORMATION! Read instruction manual before operation. Be sure to comply with all “Contraindications”, Warnings”, “Cautions” and “Adverse reactions” in the manual. Failure to follow instructions can cause harm to user or device. 1.4 Contraindications 1)
2)
This device should not be used for symptomatic local pain relief unless etiology is established or unless a pain syndrome has been diagnosed. This device should not be used when cancerous lesions are
5
present in the treatment area. Stimulation should not be applied over swollen, infected, inflamed areas or skin eruptions (e.g. phlebitis, thrombophlebitis, varicose veins, etc.). 4) Electrodes must not be applied to sites that might cause current/stimulation to flow through the carotid sinus region (anterior neck) or transcerebrally (through the head). 5) Do not use this device if the patient has a demand-type cardiac pacemaker or any implanted defibrillator. 6) This device should not be used over poorly enervated areas. 7) Epilepsy 8) Serious arterial circulatory problems in the lower limbs 9) Abdominal or inguinal hernia 10) Do not use this device if you have heart disease without consulting your physician. 3)
1.5 Warnings, Cautions and Adverse Reactions WARNINGS: 1) This device should be used only under the continued supervision of a licensed physician. 2) The long-term effects of chronic electrical stimulation are unknown. Electrical stimulation devices do not have any curative value. 3) TENS is a symptomatic treatment and, as such, suppresses the sensation of pain, which would otherwise serve as a protective mechanism. 4) Safety has not been established for the use of therapeutic electrical stimulation during pregnancy. Do not use during pregnancy unless directed by your physician. 5) Electrical stimulation is not effective for pain of central origin. 6) Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not operate properly when electrical stimulation is in use. 7) Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the
6
carotid sinus reflex. Stimulation should not be applied over the anterior 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. 9) Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause cardiac arrhythmias. 10) Stimulation should not take place while the user is connected to high-frequency surgical equipment, it may cause burn injuries on the skin under the electrodes, as well as problems with the stimulator. 11) Do not use the stimulator in the vicinity of shortwave or microwave therapy equipment, since this may affect the output power of the stimulator. 12) Never use in environments with high humidity such as in the bathroom or when having a bath or shower. 13) Caution should be used in applying electrical stimulation to patients suspected of having heart disease. Further clinical data is needed to show there are no adverse results. 14) Never use near the heart. Stimulation electrodes should never be placed anywhere on the front of the thorax (marked by ribs and breastbone), but above all not on the two large pectoral muscles. Here it can increase the risk of ventricular fibrillation and lead to cardiac arrest. 15) Electrodes should not be placed over the eyes, in the mouth, near the genitals or internally. 16) Never use on the areas of the skin which lack normal sensation. 17) Apply the electrodes to clean, dry, and unbroken skin only. 18) Keep electrodes separate during treatment, electrodes in contact with other could result in improper stimulation or skin burns. 19) Keep the stimulator out of reach of children. 20) Consult your doctor if you are in any doubt whatsoever.

CAUTION: Do not insert the plug of the patient lead wire into any AC power supply socket. 4.4 Electrode 4.4.1 Electrode options The electrodes are disposable and should be routinely replaced when they start to lose their adhesive nature. If you are unsure of your electrode adhesive properties, order new replacement electrodes. Replacement electrodes should be re-ordered through or on the advice of your physician to ensure proper quality. Follow application procedures outlined in electrode packing, to maintain optimal stimulation and to prevent skin irritation.
17
4.4.2 Place electrodes on skin Apply electrodes to the exact site indicated by your physician or therapist, before applying electrodes, be sure the skin surface over which electrodes are placed is thoroughly cleaned and dried. Make sure the electrodes are placed firmly to the skin and make good contact between the skin and the electrodes. Place the electrodes over the skin; attach them properly, firmly, and evenly. CAUTION: 1)
2) 3) 4)
Before applying the self-adhesive electrodes, it is recommended to wash and degrease the skin, and then dry it. Do not turns on the device when the self-adhesive electrodes are not positioned on the body. Never remove the self-adhesive electrodes from the skin while the device is still turns on. It is recommended that, at minimum, 40mm x 40mm self-adhering based, square electrodes are used at the treatment area
4.4.3 Electrode placement The placement of electrodes can be one of the most important parameters in achieving success with therapy. Of utmost importance is the willingness of the physician to try the various styles of electrode placement to find which method best fits the needs of the individual patient. Every patient responds to electrical stimulation differently and their needs may vary from the conventional settings suggested here. If the initial results are not positive, speak to your physician about alternative stimulation settings and/or electrode placements. Once an acceptable placement has been achieved, mark down the electrodes sites and the settings, so the patient can easily continue treatment at home.
