Devices that employ external compression stocking-type garments in the treatment of edema, chronic wounds, deep venous thrombosis prevention or claudication all share a number of significant limitations. These include the frequent need for custom fitting to assure an appropriate fit, vigilant maintenance to assure a continued “good fit,” limited compliance with proper use by patients and difficulty of application. There is a large body of evidence demonstrating that patients often decline to wear the compressive stockings as prescribed or in the form that would be most beneficial because they find these devices to be difficult to put on and take off.Building on the limitations of existing therapies, and distilled lessons learned from the field of prosthetics and wound healing, the present invention employs vacuum-assisted negative pressure to provide compression and help pump fluid from the tissues of affected limbs. The device is embodied in the form of a flexible stocking-like garment that will utilize a pumping mechanism to generate negative pressure around the limb and thus create vacuum compression that will mobilize fluid in a limb and increase venous return to the heart. Through the use of a circumferential wrap, the present invention provides a major advance in both the distribution of vacuum and the securing of the device over the limb.

Systems, devices and methods for providing active and / or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and / or compression stockings to provide feedback to modulate the compression treatment parameters.

A compression stocking, a weaving process of the compression stocking, and a seamless hosiery machine applied in the process. A stocking body (2) of the compression stocking comprises a stable region (11), compression gradually-changing regions (12, 13, 14), and a compression difference region. The stable region (11) is connected to a stocking foot (3). A length parameter (LA) and a middle girth parameter (B) of the stable region (11) are set separately according to a length parameter (LA) of an ankle and a girth parameter (cB) of a thinnest part of the ankle. The interface compression in the stable region (11) is kept consistent. The compression gradually-changing regions (12, 13, 14) are located between the stable region (11) and a welt (1), the stable region (11), the compression gradually changing regions (12, 13, 14) and the welt (1) are sequentially connected from bottom to top. The interface compression in each of the compression gradually-changing regions (12, 13, 14) gradually decreases from bottom to top, the interface compression of the joint of the neighboring compression gradually-changing regions (12, 13, 14) is kept successive, and each of the compression gradually-changing regions (12, 13, 14) has a preset compression gradually-decreasing gradient. The compression difference region is located in a local region surrounded by the stable region (11) and / or the compression gradually-changing regions (12, 13, 14). The interface compression in the compression difference region may be distributed in a gradient manner or in an even manner. The compression stocking can meet requirements for the specific compression magnitude and the distribution of different parts of a lower limb.
