A61F5/019)} - A61F: FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR

support long-term bedridden patients, characterized in that the foot support includes a preformed support of two parts, i.e. a top piece (2) that consists of a stiff cushion (3) with an erect wall (4) and transverse supports (5,6,7) connected to it for the lateral support of the lower legs (16), and a bottom piece that consists of a base (8) on which the lower legs can rest and whereby the base (8) has a pair of cambers (10) to support the lower legs (16), and whereby the base (8) can be exchanged by a base with different cambers (10) suitable for another leg dimension, and whereby the top piece (2) can be removed to gain access to the legs of the patient who remains lying on the base (8), without having to move this base (8) or the legs (16). ## Claims ### Claim 1 Orthopaedic foot support to support long-term bedridden patients, characterised in that the foot support comprises a preformed support of a top piece and a bottom piece, wherein the top piece consists of a stiff cushion with an erect wall and transverse supports connected to it for the lateral support of the lower legs, and the bottom piece consists of a base on which the lower legs can rest and whereby the base has a pair of cambers to support the lower legs, and whereby the base can be exchanged by a base with different cambers suitable for another leg dimension, and whereby the top piece can be removed to gain access to the legs of the patient who remains lying on the base, without having to move this base or the legs, and whereby the base and the erect wall of the top piece form a right angle or practically form a right angle so that the feet form a right angle or practically form a right angle with respect to the lower leg. ### Claim 2 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that between the camber to support the lower leg and the upright wall of the top piece there is a hollow in the base and the upright wall such that the heel is located floating above the underlying base. ### Claim 3 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the top piece can be detached from the base to remove it and it can be secured after being put back on the base. ### Claim 4 (depends on 3) Orthopaedic foot support according to claim 3, characterised in that the top piece can be secured to the base with a hinge so that the top piece can be turned upwards to release the legs. ### Claim 5 (depends on 3) Orthopaedic foot support according to claim 3, characterised in that the top piece can be secured to the base by means of buckles or fasteners. ### Claim 6 (depends on 3) Orthopaedic foot support according to claim 3, characterised in that the top piece and the base can be secured to one another by sliding them together, and can be slid apart to remove the top piece. ### Claim 7 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the pair of cambers on the base is made from a material that automatically takes on the shape of the lower leg of the patient, such as a viscoelastic foam or a gel pad. ### Claim 8 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the edge of the base that is the closest to the back of the knee of the supported legs, has a height between 1 and 3 cm in order not to load the knee joint. ### Claim 9 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the base is no larger than the movable surface of a positionable hospital bed on which the lower legs rest. ### Claim 10 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the central support of the transverse supports, that keeps the two legs separate, can be detached to enable a sideways position for the patient. ### Claim 11 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the base and/or the top piece is covered on the underside with an anti-slip material, in order to prevent it sliding away when the support surface is on a slope. ### Claim 12 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the top piece and/or the base are made from a hard foam, such as polyether or polyurethane or a medical cold foam. ### Claim 13 (depends on 12) Orthopaedic foot support according to claim 12, characterised in that the hard foam consists of a mix of different foam types with possible different densities. ### Claim 14 (depends on 12) Orthopaedic foot support according to claim 12, characterised in that the hard foam is of a fire-retardant type. ### Claim 15 (depends on 12) Orthopaedic foot support according to claim 12, characterised in that the hard foam is an antibacterial and/or antiviral medical foam. ### Claim 16 (depends on 12) Orthopaedic foot support according to claim 12, characterised in that the hard foam core is covered with a softer material to improve the lying comfort of the patient. ### Claim 17 (depends on 16) Orthopaedic foot support according to claim 16, characterised in that the covering of the hard foam core is constructed in the form of a liner or coating. ### Claim 18 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the foot support consists of or is covered with a material that has properties to prevent bedsores. ### Claim 19 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the foot support is covered with a material that has antibacterial, antiviral and/or antifungal properties. ### Claim 20 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the foot support consists of or is covered with a material that can be washed or sterilised at 95° C. ### Claim 21 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the cambers in the base are formed by inserts chosen from a range of preformed inserts with cambers, according to the physiognomy of the lower leg and foot of the patient. ### Claim 22 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the top piece and/or base are equipped with securing means to secure them in place at the foot end of the bed. ### Claim 23 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that height of the stiff upright cushion of the top piece is such that the patient can at most stretch out his toes above the stiff upright cushion. ### Claim 24 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the stiff upright cushion of the top piece has one or more extension pieces that ensure that the bed covers over the foot support do not come into contact with the feet of the patient. ### Claim 25 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that a band at the level of the lower legs is attached around the cushion. ### Claim 26 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the three transverse supports include a central support that is intended to be placed between the legs of the patient in order to ensure a straddle position of the legs, and the other two supports are side supports on either side of the legs. ### Claim 27 (depends on 1) Orthopaedic foot support according to claim 1, characterised in that the transverse supports slope downwards in their longitudinal direction from the upright cushion to the edge of the base that is closest to the backs of the knees, in order to keep the upper legs warm with the bed covers.
