The present invention is directed to a pain-relieving treatment belt that comprises a plurality of pockets positioned on its interior surface which target the vertebrae of the lumbar spine and house a plurality of balls comprised of a thermally conductive material. The balls are designed to provide heat or cold therapy, as well as pressure and massage to the lumbar spine. The balls may be heated or cooled, and movable, to target specific spinal discs and muscles in the lumbar region. The belt is designed to rehabilitate the lower back by promoting circulation and alleviating inflammation and other ailments through the use of heated or cooled balls that rotate and apply pressure to targeted parts of the lower back.

At least some aspects of the present disclose feature a flow control device to be used between two inflatable sections. The flow control device is a one-way flow control device allowing inflating medium to flow in one direction. In such embodiments, the flow control device is in an open state when a first inflatable section is inflated such that a second inflatable section is also inflated. The flow control device is in close state when the second inflatable section is inflated such that the first inflatable section is not inflated.

A cooling blanket, singularly or in plurality, which covers the core body of humans or animals to facilitate immediate, rapid cooling through sweat evaporation and radiant heat exchange by means of an integrated ventilation system and maximum body surface contact via an incorporated cooling medium contained within multiple, sealed compartments within the embodiment.

The present invention provides a scalp cooling device, including a covering part for wrapping a patient's scalp and a cooling part disposed within the covering part. This device can wrap around the patient's scalp and provide a cooling effect, causing the blood vessels in the scalp skin to constrict, reducing the blood flow to the scalp hair follicles, thereby reducing the intake of chemotherapeutic drugs by the hair follicles. Additionally, it lowers biochemical activity, thereby reducing the sensitivity of hair follicles to chemotherapy damage, and reduces the metabolic rate of the hair follicles, thus protecting the patient's hair follicles and preventing or mitigating hair loss caused by chemotherapy. Notably, the cooling part includes a gel-like coolant, which contains a moisture moderator and edible propylene glycol that maintains moisture and provides emulsifying and stabilizing effects, thus offering a long-lasting and stable cooling effect, enhancing the device's effectiveness in preventing hair loss.
