Long-lasting Cold Therapy: The knee ice machine utilizes a continuous circulation system to pump ice water into the pad to provide soothing cold therapy to the body. With superior insulation properties, three frozen water bottles can provide hours of continuous cold therapy, promoting faster healing and long-term relief to improve overall quality of life. Personalized Therapy Experience: Easily customize your therapy with adjustable flow rate (L1 to L6) and various timers (10 to 60 minutes, always on) for optimal comfort and results. The cryotherapy machine is equipped with a low-noise pump, operating at 15 dB, ensuring a quiet, undisturbed experience even when resting or using it at night. Insulated Leak-Proof Design: The cold therapy system's multi-layer durable insulation design, zippered leak-proof lid and efficient delivery insulated hose ensure that the ice water maintains the optimal temperature for a long time. The uniquely contoured, ergonomic knee therapy pad evenly distributes the ice water for effective and targeted therapy.
