Pneumatic Shockwave + Ultrasound Machine – JN-USM Model

The JN-USM is a combined physiotherapy device that integrates pneumatic shockwave therapy and therapeutic ultrasound into a single unit to support pain relief, soft-tissue rehabilitation, musculoskeletal recovery and accelerated healing in clinic or supervised home settings.

Shockwave delivers focused mechanical pressure pulses to break adhesions, reduce calcifications and stimulate tissue repair, while ultrasound converts acoustic energy into deep heat to increase circulation and metabolism. Combining both modalities allows complementary effects—mechanical stimulation plus thermal/biological enhancement—for more comprehensive treatment.

Common indications include delayed fracture healing and nonunion, early femoral head necrosis, calcific supraspinatus tendonitis, frozen shoulder, long head of biceps tendinitis, lateral/medial epicondylitis (tennis/golfer's elbow), plantar fasciitis, insertional Achilles tendinopathy and some lumbar disc-related symptoms when indicated by a clinician.

Shockwave energy: 1–6 BAR; shockwave frequency: 1–21 Hz; shockwave working head with 12 interchangeable tips; tip life: ~5 million pulses. Ultrasound energy: 1–3 W/cm² at 1 MHz. Machine power: 250 W. Interface: 10.4-inch touchscreen.

Start with lower energy and frequency settings and increase gradually based on patient tolerance and clinical response. Use lower shockwave energies for sensitive areas and higher energies for chronic calcifications; ultrasound intensity and duration depend on tissue depth and goals. Follow established treatment protocols or a clinician's guidance.

Typical sessions last 5–20 minutes depending on modality and condition. Shockwave courses often include 3–6 sessions spaced 3–7 days apart; ultrasound can be applied more frequently (e.g., 2–3 times weekly) depending on the protocol. Individual plans should be set by a treating clinician.

Contraindications commonly include pregnancy (over abdomen/pelvis), active infection or malignancy at the treatment site, over untreated growth plates in children, presence of an untreated blood clot or thrombus, and areas with impaired sensation or implanted electronic devices (consult manufacturer/physician if pacemaker present). Use caution if the patient is on anticoagulants and always screen patients prior to treatment.

The JN-USM is classed as a Class I medical device, which meets basic safety standards; however, safe and effective use requires training. Home use should be under the direction of a healthcare professional or after adequate device/operator training and follow-up.

The system uses interchangeable shockwave tips (12 supplied tip types) and ultrasound coupling gel. Other consumables include replacement tips over long-term use and routine cleaning supplies. Confirm the exact included accessories with the supplier.

'Bullet life' refers to the expected durability of the shockwave applicator tips—specified as approximately 5 million pulses for the JN-USM—after which tips should be inspected and replaced if wear affects performance.

Turn off and unplug before cleaning. Wipe external surfaces and the touchscreen with a soft cloth dampened with mild detergent or manufacturer-approved disinfectant. Clean the ultrasound transducer with recommended gel-removal procedures and disinfect shockwave applicators per manufacturer instructions. Schedule periodic professional servicing as recommended.

The device has a 250 W power rating. Confirm local mains voltage compatibility and ensure a stable power supply and properly grounded outlet. For clinic installations, allow adequate space for ventilation and operator access to the 10.4-inch touch screen.

Common transient effects include mild-to-moderate discomfort during treatment, temporary redness, bruising, soreness or local swelling. Serious complications are rare when used correctly, but any unexpected or severe reactions should prompt cessation and medical review.

Yes. Operators should receive training on both shockwave and therapeutic ultrasound principles, device settings, safety protocols and patient selection. Many jurisdictions require a licensed healthcare professional to operate such devices; check local regulations and supplier training programs.
