The present invention provides a device for providing intermittent compression to a limb, the device comprising, an at least one energy reservoir and an at least one compressing means for compressing the limb, wherein the energy stored in the at least one energy reservoir is pre-stored in the energy reservoir and is directly transformed to provide intermittently compression on the limb. The energy reservoir provides a single energy transformation from energy stored in the reservoir to energy used to compress intermittently the limb. Optionally, the energy stored in the reservoir also provides the energy for a mechanism controlling the intermittent operation of the device and the release of excess energy from the device.
