Inventors include S. Pavithra; N. Kayalvizhi; G. C. Dharisana; C. Krija; and M. S. Nisha.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present invention relates to a wearable, zone-specific, response-verified and closed-loop multimodal calf therapy apparatus for applying controlled compression and neuromuscular electrical stimulation (NMES) to a lower limb. Varicose veins represent a significant lower-limb venous health problem internationally, affecting approximately 33 million women and men aged 40-80 years in the United States, while Indian studies have reported substantial occurrence in specific occupational and regional populations. To address the need for controlled and individualized lower-limb therapy, the apparatus comprises a calf-mounted support structure having four independently controllable treatment zones, including two zones positioned on an upper calf region and two zones positioned on a lower calf region. The apparatus further comprises controllable compression elements, interface-pressure sensors, photoplethysmography (PPG) sensors, temperature sensors, NMES electrodes, electromyography (EMG) sensing electrodes, a controller and a detachable magnetic-pin electrical connector configured to connect the controller to a separate display unit. The controller establishes zone-wise baseline measurements, regulates compression according to actual limb-interface pressure, selectively delivers NMES, verifies resulting muscle activation using EMG measurements and evaluates quality-screened physiological measurements obtained before, during and after therapy. The controller stores therapy-response data and adapts subsequent compression and NMES parameters within predefined operating and safety limits. An optional vibration actuator may provide vibration therapy.
