ELASTIC COMPOSITE MATERIAL

Device for putting prostheses into place

The present invention relates to a device for pulling on the jersey stockings for putting contact prostheses into place. It allows, in particular, an amputee who has lost a lower or upper limb to put his/her prosthesis into place independently and without effort. It also makes it possible to lighten the work load of the hospital staff involved in assisting amputees in specialised rehabilitation centres. The device comprises a stop piece (10) adapted to bear around the orifice (2) of the end of the insert part (1) of the prosthesis, a self-locking catch (12) designed to hold the jersey stocking (1B) tightly over the whole of its cross-section, or over only a part thereof, a traction carriage (11) which slides on a slideway frame (6) and which drives the locking catch (12). The displacement of the traction carriage (11) can be obtained manually by pressing the grips (6A, 8) or electrically by means of an endless screw driven by a motor. The device makes it possible both to guide the prosthesis (1) towards the stump to be fitted (1A), to pull tightly on the stocking (1B) and to perform this manoeuvre using only one hand, since the device holds itself in position starting from the onset of the traction. The position of the grips (6A, 8) is ideal from the ergonomic point of view, both for the amputee and for a third party.

The padding is in the form of a gel which can be used alone or in combination with various other materials such as fabrics. Typically, the invention is in the form of two-piece formfitting sleeve member. One piece (1a) is designed to cover the bony prominance of a stump and come up over the knee, and another piece (1b) is designed to circumscribe the soft tissue around the stump.

Sheath for suction stump holder of artificial limb - has sleeve with elasticated collar to protect wearers skin against rubbing

The sheath fits over a suction type stump holder for an artticial limb protects the wearer's skin against rubbing. It comprises a sleeve (1) with an elasticated collar (7) at one end, fitted to the outside of the holder (1) and held by a draw string and an adhesive band (8). The body (5) of the sleeve is folded over the top (6) of the holder and extends inside it. The stump (2) is fitted with a stocking and eased into the holder, a string passing through the suction the hole (3) being used to guide and remove the stocking. The sleeve pulls tight to fit closely around the stump.

Prosthesis retainer

A plurality of sheaths extend along the sleeve of a socket prosthesis. The outermost, or retaining sheath is open at top and bottom and extends from above the sleeve down over the prosthesis itself. Different portions of the retaining sheath have different degrees of elasticity. An inner sheath is first folded over the top edge of the retaining sheath, and then folded again, together with the retaining sheath, to form a welt which abuts against the upper edge of the prosthesis sleeve.

Polymeric prosthetic liner with controlled stretch characteristics

Shape memory elements for medical aids

Die Erfindung betrifft medizinische Hilfsmittel, besonders Körperstützbandagen und Orthesen, für den menschlichen oder tierischen Körper mit mindestens einem Stützkraft, Kompression oder Druckeinleitung erzeugenden oder vermittelnden Element, das Formgedächtnismaterial aufweist oder daraus besteht. The invention relates to medical aids, especially body support bandages and orthotics, for the human or animal body with at least one element that generates or mediates support force, compression or pressure initiation, which has or consists of shape memory material.

Apparatus and process for making prosthetic suction sleeve

The method of making a tubular member having a continuous and uninterrupted cured elastomeric resin coating on an outer surface of the member includes forming a continuous uninterrupted tubular layer of uncured elastomeric resin and drawing the resin layer against the surface of the tubular member to be coated by applying suction between the resin layer and the surface of the tubular member so that the resin adheres to the surface of the tubular member. The elastomeric resin may then be cured to produce the final product. Apparatus for carrying out the process is disclosed and includes, in sequence, a coating zone including a sub-atmospheric chamber, a heating zone and a feed mechanism for advancing the tubular member relative to the coating and heating zones. A method is also disclosed for molding a distal end cap on an open end of a length of a preformed tubular sleeve member that may be used for prosthetic applications. A process is also disclosed for molding a sleeve member having prosthetic applications using male and female die elements used to distribute uncured elastomer resin as a layer on a tubular elasticized fabric sleeve element.

Socket liner for limb prosthesis

A method of preparing a breathable, custom-molded liner for an artificial limb socket includes the steps of providing a liner comprising an open-celled foam material impregnated with a curable resin, activating the curable resin, and deforming the foam material by positioning residual limb on one of opposing surfaces of the liner, and positioning the artificial limb socket on a second opposing surface of the liner until curing is substantially complete to create and retain an impression of the residual limb in the foam material. A liner blank useful for preparing an artificial limb socket, comprising a foam material impregnated with a curable resin and sewn into the shape of a sock for an artificial limb, is also described.

Vacuum assisted prosthetic sleeve and socket

A prosthetic sleeve and socket system, the sleeve including a flap or skirt concentrically arranged about the sleeve and configured to form a sealed chamber between the sleeve and socket when the sleeve is inserted into the socket. An air permeable material is interposed between the skirt and the sleeve to maintain a continuous interconnected air layer therebetween. An expulsion valve is provided to allow air contained within the sealed chamber to be forced out of the chamber ahead of the sleeve when it is inserted into the socket. A powered vacuum pump is also provided for producing and maintaining a partial vacuum in the sealed chamber for keeping the socket and sleeve joined. The system allows for a substantial reduction in size of known sockets and permits, in some instances, the disposal of bulky suspension straps currently in use to force the socket against a residual limb.

Vacuum pump and shock absorber for artificial limb

A weight-actuated vacuum pump and shock absorber for an artificial limb. Ambulation causes the vacuum pump, under the influence of the wearer's body weight, to draw air out of the artificial limb socket cavity, producing a vacuum within the socket. The vacuum pulls the residual limb into firm and total contact with the socket and prevents the loss of fluids in the residua l limb. A shock absorber acts in conjunction with the vacuum pump to reduce th e shock of impact on the wearer caused by ambulation.

Prosthetic liner and additive manufacturing system, method, and corresponding components for making such prosthetic liner

An additive manufacturing system and method for making components having filaments formed by elastomeric materials. A liner includes the filaments formed by an elastomeric material and is adapted for a prosthetic device system. The filaments form an elastomeric lattice structure and solid layers or features and define a ventilated structure permitting a transfer of air and moisture from an interior volume of the liner to an exterior or ambient liner. The liner may incorporate an adhesive and a textile layer secured to the elastomeric lattice structure and further define recesses and other features for improving a liner.

Stump stocking

Prosthetic sleeve

A sleeve for mounting a prosthetic unit on a limb is formed in a knitted fabric comprising elastic yarns to allow circumferential extension of the sleeve to grip the limb. Adherent fibres are integrated within the fabric and exposed on the internal surface of the sleeve to provide additional grip. Such fibres can be silicone or silicone based yarns. An end of the sleeve is adapted to couple with a prosthetic unit. The knitted fabric may include yarns of restricted elasticity to limit longitudinal extension of the sleeve, and the elastic yarns and the yarns of restricted elasticity are typically located in discrete sections (2, 4, 6) of the sleeve. Such discrete sections will normally extend longitudinally in the sleeve. The knitted yarns at the end of the sleeve are normally bonded directly to a coupling element (8, 10, 12) for attachment to a prosthetic unit.
