Abstract

A sleeve comprises a rigid supporting sheath of plastic material to the upper part of which at the lateral surface area a sleeve volume regulating element is attached. At the lower part of the supporting sheath an element of prosthesis connector regulating assembly (sleeve adapter) is arranged. The inner sleeve is made of soft material, e.g. Pedilen. Fastening elements fixed to the outer surface of the supporting sheath are made of Velcro strap.

p. 60). To the upper end of the hard shell in the lower leg area in a removable state. an internal receiving sleeve is attached to the cutout. The receiving sleeve includes a front hard one made of leather. An incision was made on the back surface of the inner supporting shell 1, made in the shape of a stump from a hollow receiving sleeve made of leather. zoom along the back wall, to the upper part of the carrier

On the edges of the cut, fastening elements are installed, the hard shell 1 in the area of the side surface is made in the form of lacing. In the upper part, with the help of hinge 2, the element Z of the regulating sleeve is attached at the level of its own connection of the volume of the sleeve (rear part), made of a linna, the fastening elements are installed, made in the shape of a stump, which along the joint line is installed in the form of strap The design allows for the rigid supporting shell 1. In the lower part of the inner leather-woven supporting shell 1 rigidly installed e-sleeves are installed in the lower part of the shoelaces to reduce the internal volume in accordance with ment 4 of the connecting and regulating node of the prosthesis with the dimensions of the volume of the stump.

This receiving sleeve is accepted as a prototype. nor on the outer surface of the supporting shell 1 and

The disadvantages of the well-known receiving sleeve are that it is made, for example, of Velcro tape. The total contact-bearing shell 1 and the element of adjustment of the volume of the inner surface of the sleeve and stump are stiff due to the insufficient stability of the sleeve, which is due to the use of leather in the rear part of the case made of thermoplastic or layered plastics. . the sleeve does not provide a stable front- To protect the stump in a rigid supporting shell 1 rear size in the area of the landing ring and an internal sleeve 6 is placed, made of the shape of the sleeve varies under load. In addition, the zom is made of a soft material, such as pedilene, which makes lacing on the back surface inconvenient. Six cases are accompanied by dragging. stumps when using it. To install the stump, element C is adjustable

The technical task of the invention is to increase the volume of the sleeve (rear part) and raise the functional and operational characteristics upwards by turning it with the help of a hinge 2. receiving sleeves for lower leg prostheses. The coax is installed in the inner sleeve 6, located

This task is solved by the fact that in the receiving hole in the rigid supporting shell 1, attached to the leg of the lower leg prosthesis, which includes the rigid supporting element 4 of the connecting and regulating shell made of plastic material, made on the node (sleeve adapter) to the lower leg prosthesis. in the form of a stump with a cutout on the back wall, the inner Element 3 adjusting the volume of the sleeve along the line of the joint, the receiving sleeve and the fixing elements, the difference is that they are installed in a rigid carrier shell 1, but there is the fact that it is pressed to the upper part of the rigid carrier until it is fully of contact with the stump and fix- the shell in the area of the side surface with the help of 5 fixing elements, with the hinge attached to the volume adjustment element, this controls the convenience of fitting the sleeve on the sleeve, made in the shape of a stump made of a plastic stump for a disabled person when walking. When reducing the volume of material; in the lower part of the rigid bearing stump, the element of the sleeve of the base is rigidly installed. The connecting element is pressed to the front rigid bearing shell of the adjusting node of the prosthesis (sleeve adapter 1 and fix it in this position. With the sbilter) ; the inner receiving sleeve is made of mixed volume of the stump, 5 fixing elements of a weakening material, for example, pedilene; the elements are, while the element Z adjusting the volume of fixation, fixed on the outer surface of the bearing sleeve departs from the front rigid bearing shell and is made, for example, from Vel-sheath tape 1, reducing the pressure on the stump. cro In the UkrNDprosthetics for primary prosthetics

The receiving sleeve of a lower leg prosthesis due to the use of a disabled person with a complex "club-like" detachable joint joint of a rigid non-supporting stump, an experimental shell with a cutout on the back wall and an element- sample of a removable sleeve of a lower leg prosthesis of such a cons- and volume adjustment was made sleeve made of plastic. The use showed the convenience of the operative material, it allows to stabilize the prosthesis, improve the condition of the soft tissues, and adjust the volumetric dimensions of the gis and load-bearing capacity. tears over the entire surface of the stump and stabilize these ro- The patient's feedback is positive. measurements using fasteners. Thus, the design ensures a uniform distribution of pressure on the surface of the volumetric dimensions of the receiving sleeve of the protection and its tight fit to the sleeve without disturbing the leg in accordance with the volumetric dimensions of blood circulation, which increases functional and stumps during operation, total contact performance characteristics of the prosthesis of the leg sleeve with the stump and uniform distribution of pressure on the surface of the stump, which is difficult for prosthetics, which prevents violations of the stump edges and fluctuations in volumetric dimensions. in circulation, increases functional and operational

The essence of the invention is explained by the drawings, which show the characteristics of the lower leg prosthesis for the disabled: stumps difficult for prosthetics, for example, fig. 1 - general view of the receiving sleeve of a "club-shaped" shape or with swelling when the lower leg is folded, side view; vascular diseases or immediately after amputation.
