Description

The invention relates to a support device for medical or physiotherapeutic treatment of extremities, comprising a support with a base body, wherein the support is integral with the base body or the support is designed to be connectable with the base body and at least parts of the support form a base for the support device. Positioning aids for extremities are used in operative orthopedics or surgery to, for example, keep a patient's leg extended or fully or partially bent as needed during knee surgery. For this purpose, positioning aids are temporarily attached to a surface, such as an operating table. These attachments are usually secured using straps with quick-release fasteners (e.g., Velcro). Such positioning aids are often combined with a separate lateral support, particularly for leg positioning aids for a patient's thigh and/or lower leg. Barrel-shaped support elements can be positioned next to the patient's lower leg, with the support elements having different heights and being spaced parallel to each other across a longitudinal axis, so that the height of the support elements varies from the lowest to the highest. However, the problem is that a support device used in situations requiring less elaborate preparation, especially for legs and lower legs, does not have a suitable support surface with a flat, stabilizing area, so that tipping of an extremity, be it arm or leg, during treatment cannot be prevented. Several devices are already known from the prior art that ensure the stabilization of at least a part of an extremity on a support surface during medical treatment. Thus, from the WO 2020229812 A1 A pillow for the front of the foot is known, in which a pillow can be arranged around the foot in a dorsal position during sleep. The pillow is configured to stabilize the ankle and guide the foot into dorsiflexion, while the front of the foot and ankle face the sleeping surface. Furthermore, the DE 20002035 U1 A medical lower leg cuff designed as a positioning aid to relieve heel pressure. The cuff features a foam sleeve adapted to the anatomical shape of the calf, such that the thickness of the foam prevents the heel from touching the surface while lying down. While current support devices do not prevent a limb from buckling (tipping) to the side, they do not provide lateral stabilization. If the patient or animal has to stabilize the limb using their own muscle strength, cramps often occur, and treatment must be interrupted. Therefore, lateral stabilization of the supported limb is crucial. Soft support devices tend to buckle under the weight of a heavy limb. Consequently, their soft nature provides little to no stabilization. Hard support devices, on the other hand, currently lack the ability to stabilize the limb through tilting and to provide pain-free positioning by widening the contact area. This prevents pressure relief for the supporting or surrounding tissue. The objects of the invention are to provide a stable and elevated support for an extremity on a medical device, whereby the extremity can be held in position on a support surface without effort or pain, and tipping or falling off the support surface is prevented, even under high weight. The device should have a large contact area so that pressure on the supporting and/or adjacent tissue of the extremity is minimized. This allows it to be made of a solid material and thus withstand high weight. The object of the invention is solved by the features of the underlying claim 1. According to the invention, the base body has a support surface for extremities, wherein at least partial areas of the base body with the support surface are inclined at one end relative to partial areas of the base body with the support surface at the other end, and the central area of the support surface is shaped in a trough-like form. The features of the invention are defined and explained below: A support is to be understood as a single element or a partial element of the support device, which serves as a base or foot for The support device can function as a base body with a support surface for an extremity. The support can be connected to the base body with support surface as a separate element or be designed as a component of the support device, i.e., integrally formed with the base body with support surface. The base body, as a single or partial element of the support device, comprises a support surface onto which an extremity can be placed. As a single element, the base body with its support surface should be connectable to the support, or it should be able to be formed integrally with the support device as a partial element. In this context, "individual element of the support device" means that individual pieces constitute the support device and that the support device can be assembled from several individual elements. Thus, an individual element should be connectable to another individual element, or assembled or joined together, and function together as a
