ED Extracorporeal Shockwave Therapy Machine Pain Relief Treatment Massager Instrument BlackSilver Handle UK Plug 110‑240V Condition: Item Type: Pain Relief Massager Material: ABS + Aluminum Alloy Color: Black Host Size: Approx. 26.5 x 20 x 8.5cm / 10.4 x 7.9 x 3.3in Frequency: 50-60HZ Power: 180W  Output Frequency Gears: 16 Gears, continuously adjustable: 1HZ-2HZ-3HZ-4HZ-5HZ-6HZ-7HZ-8HZ-9HZ- 10HZ-11HZ-12HZ-13HZ-14HZ-15HZ-16HZ Output Energy Gears: 25 Gears, continuously adjustable: 10mj-20mj-30mj-40mj-50mj-60mj-70mj-80mj-90mj- 100mj-110mj-120mj-130mj-140mj-150mj-160mj-170mj- 180mj-190mj-200mj-210mj-220mj-230mj-240mj-250mj Contraindications: Hemorrhagic disease: Patients with coagulation dysfunction may cause local tissue hemorrhage, and patients with untreated, untreated or incurable hemorrhagic disease should not undergo ESWT. Patients with thrombosis: ESWT is prohibited in such patients to avoid the serious consequences of thromboembolic fall off. Children with growth pain. Patients with severe cognitive impairment and mental illness. Operation preparation: Treatment site of the patient is generally pain, acid, numb, stiffness, and limited range of motion of the joint, and the shockwave is a tearing damage, repair regeneration impact. It is recommended to "warm up" treatment with manipulation, passive training or physiotherapy before treatment. For example, ankle range of motion manipulation should be done before treatment of talus injury, muscle relaxation massage should be done before treatment of leg muscle spasm, and microwave therapy should be done before treatment of calcified supraspinatus tendonitis to promote microcirculation. Methods: A. Shunting: it spreads from the starting (stopping) point to the distal end of the muscle. Advantages: it is not easy to damage the normal tissue and does not aggravate the pain;Insufficient: Long frequency, long time. B. Inverse beating: the direction is opposite to that of clockwise beating. Advantage: sometimes it can achieve amazing effect (knot principle). C. Oblique shot: the gun is at a 45 degrees angle to the skin, especially suitable for soft tissue injury around the ankle joint D. Parallel back and forth movement: it is a method of relieving pain during treatment and can also be applied to a wide range of lesions. E. Circular movement: it is a method of relieving pain during treatment and can also be applied to a wide range of lesions. Course of treatment: Generally 5-7 days once, 3-6 times for a course of treatment. Treatment time of extracorporeal shockwave therapy is about 5-15 minutes each time. For patients with short injury time, they can basically return to normal after one treatment. For old wounds, 5 to 7 treatments are required, with intervals of 3 to 7 days. Note:1. Coupling agent can be applied to the affected area before treatment, and it is forbidden to pull the trigger in the state of empty gun.Do not turn on the output when the impact head is not in contact with the affected area to avoid unnecessary damage to the equipment and the patient. 2. Shockwave therapy also has some side effects, including local tissue redness and swelling, subcutaneous hemorrhage, ecchymosis, pain, etc., but most of them are transient and can be alleviated or eliminated within 1‑2 days after treatment. 3. After treatment, drink plenty of water that day to promote circulation and expel inflammatory substances. 4. At the early stage after the end of a course of treatment, try to reduce the power generated from sports or local injuries, and pay attention to rest for 1‑2 weeks during treatment to make sure treatment sites heal. The purpose of the coupling agent is first to fill the small gaps between the contact surfaces so that the air in those gaps does not affect the energy penetration.Secondly, the acoustic impedance difference between the probe and the skin channel is reduced by coupling agent "transition", thus reducing the reflection loss of ultrasonic energy at this interface.In addition, it also act as a "lubricant" to reduce the friction between the probe surface and the skin, enabling the probe to slide more flexibly.
