Pneumatic Compression Device for Restless Legs Syndrome
Permanent address of the item is
Restless legs syndrome is neurological disorder that causes unpleasant sensations in the limbs, usually legs. These sensations can cause an irresistible urge to move the legs. Moving the affected limb can relieve the symptoms. The urge to move the legs can make falling asleep or staying asleep difficult. Restless legs syndrome (RLS) can be treated with drugs that bring relief to the symptoms. There are also non-pharmacological treatments. For example, pneumatic compression devices (PCD) can be used to treat RLS. In this thesis work, a PCD is designed and built. Treating RLS with PCDs is based on a compression to the legs. These devices use air to produce compression to stimulate the leg and affect the peripheral blood circulation. The devices consist of a controlling unit, and a wearable part that wraps around the leg. The wearable part includes one or more air bladders that can be inflated and deflated. This thesis focuses on the design and build process of the prototype device. A working prototype device is the result of this thesis work. The device being built is similar to existing pneumatic compression devices. There are differences in the basic design and the functionality compared to the existing devices.
