HAND-AND-WRIST ACCESSORY DEVICE FOR PEOPLE THAT FACILITATES EXTENSION MOVEMENTS

Abstract

Disclosed is a hand-and-wrist accessory device formed by an elasticated glove, wherein the ends of the fingers and the end of the wrist comprise an internal elasticated silicone layer that acts as a mechanical securing element for securing to the skin, these securing elements being connected to rigid structures connected to elastic elements, transmitting elastic energy from the wrist to a central floating piece on the dorsal carpus, where it is distributed to each finger terminal, the elastic elements being guided by rigid pieces disposed in the paths extending from the central piece to the finger terminals, to ensure the correct alignment thereof. These external elements have reciprocal securing elements to generate continuity from the wrist terminal to the finger or digit terminals. Cushioned elements are disposed on the palm to redistribute pressure in the wrist areas.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The (dynamic) orthotic glove that facilitates finger extension in typing work is made up of a fitted elasticated glove (1) that covers from the proximal phalanges of the thumb and medial phalanges of the fingers to the wrist joint, constituting the main body of the device where the other functional elements are housed.

[0025] The elasticated glove (1) is formed by breathable, hypoallergenic, spandex, non-toxic, washable, anti-fungal silicone microfibers in the distal areas of the fingers and wrist for the purpose securing to the skin of the hand and wrist by adhesion and compression, there being positioned in these areas rigid finger terminals (4) and a wrist terminal (15), in a wrist securing area (5) and finger securing area (2).

[0026] The rigid finger terminal (4) has two side tabs (9) for the purpose of centering the path of elastic elements (10) and has two finger connection bosses (7) which reciprocally work with elastic perforations (8) in the elastic elements (10), the elastic perforations (8) of the exotendon elastic elements (10) performing the function of generating a finger extending force when the hand is in a flexed position over a mouse or an analog computer keyboard, where the proximal part of this element has a connection terminal (11) having two extruded elastic bosses (12) which reciprocally connect with two central piece perforations (14) of a central piece (13) for the purpose of being mechanically secured and generating a tension graduation system depending on the selection of coupling points, generating a connectivity with the elastic structures disposed from the wrist securing element (5) to the rigid finger terminals (4), being attached in the central piece (13) on the dorsal part of the hand, said central piece (13) defining five slots (20) each with at least two central piece perforations (14).

[0027] The wrist securing element (5) has a certain height from its securing point with the terminals for the elastic elements (10) and a joining piece (15) for the purpose of preventing friction between the aforementioned elastic pieces and the textile material of the glove.

[0028] The objective of the wrist securing element (5) adhered on the surface of the wrist (3) which internally comprises silicone is to project the joining piece (15) from an removable articulation to the central piece (13) in the area of the carpus of the glove of the hand, being secured to same by means of the articulation comprising a male articulation piece (16) with a shape extending onto a female articulation piece (17) designed to be reciprocally coupled and thereby generate continuity between external pieces.

[0029] The objective of the finger exotendon elastic structures or elastic elements (10) is to generate an elastic force towards finger extension and to restrict hand and finger flexing in typing positions and in positions where work is done on personal computers, or PCs, where the finger exotendon elastic structures are guided along a specific path of each tendon of the common extensor of the fingers by means of rigid guides (18) having two rigid guide side tabs (19) guiding the path of the elastic elements (10) over the metacarpals and the proximal phalanges of the hand and thumb, where the modular design allows replacement of these elastic elements (10) so as to customize them, adjust the tension, or perform maintenance.

[0030] The palm comprises external cushioned elements or pads disposed in anatomical positions for the purpose of releasing loads from areas where tendons, muscles, and nerves are located. The pads of the radial area (21) and the pads of the ulnar area (22) are disposed with a separation between them to favor loading on areas of the path of the radius and of the ulna, together with pads in the thenar area (24), the hypothenar area (25), and on the area of the palmar digital protuberance (25), being disposed to release pressure loading on the path of the carpal tunnel and hollow center of the palm where the main flexor tendons are located and to favor ventilation.
