FR2860707A1 - Antispasticity splint for e.g. person with spastic hand, has thumb articulated on continuous fore-arm dorsal wall at level of wrist by rivet, and assembly of insertion clip and hook attachment forming point of fixation of thumb - Google Patents

Abstract

The splint has a continuous fore-arm dorsal wall with a ventral finger support. The wall has two velvet Velcro straps (5,6) opposite to which an adhesive hook Velcro strip (7) is placed. Another strip (15) is placed at level of wrist. A thumb is articulated on the wall at the level of the wrist by a rivet (4). An assembly of an insertion clip (1) and hook attachment (2) forms point of fixation of the thumb.

Description

FOREWORD

  The present invention relates to the realization of a two-device hand orthosis, the first facilitates the establishment without tugging, and allows to relax a prolonged posture of the hand without removing the orthosis. The other device allows the installation of the index finger, the middle finger, the ring finger and the little finger by an interdigital posture. The depth adjustment by the pads can be adjusted and the skin respected.

  This orthotic system is intended for people with a spastic hand, perhaps also used in rheumatology (ex: cubital wind).

  Currently there is already an antispastic hand orthosis by interdigital positioning but its concept of realization (thermoformable realized in one piece) leads to difficulties of setting up and passage of the five fingers, (possible articular traumatisms), cutaneous conflicts (friction ), inflammatory reactions and pain (tightness). All this calls into question acceptability and effectiveness, sometimes leading to the abandonment of conventional orthoses.

  The devices according to the invention make it possible to remedy these drawbacks.

  The first feature is a joint by a rivet on the gutter of the thumb, which creates additional mobility and allows the passage of five fingers in two steps.

  The second characteristic is the shape of the gutter of the thumb, which on a hand in pronation position, has in its upper part at the level of the nail pallet, a claw attachment (2), made by folding downwards outside the gutter to fix the thumb in good position after installation, on the insertion clip (1).

  Thus, this system makes it possible to set up the index finger, the middle finger, the ring finger, the little finger, and then to carry out the passage of the thumb by means of the articulation described above. This allows to find the latter who is often in the position of adduction without causing tension on the joint.

  The third characteristic is the posture of the index finger, the middle finger, the ring finger, and the little finger by three soft, inelastic soft fabric blades on which an ergonomic pad (13) of sponge foam, called a separator, slides. digital. Because it slides, this system promotes the establishment of these four fingers by clearing the passage.Thus, the two processes facilitate the establishment of this orthosis and achieve optimal comfortable posture. It is also possible to design a variant of this orthosis which preserves the mechanism of the thumb, but which removes the system of the three blades and the ergonomic pads. We obtain the simple antispasticity orthosis which is more intended for the uncomplicated spastic hand. The accompanying drawings illustrate the invention.

  Figure 1/2 shows the antispastic orthosis with digital posture. Figure 2/2 shows the simple antispastic orthosis.

  With reference to this drawing 1/2, for the realization of this orthosis, is used a thermoformable low temperature (70) for shaping the orthosis. It is done in four parts.

  Characteristic embodiment of the first part which receives and holds the wrist and the four fingers of the hand leaving the palm free, by a dorsal forearm flap in continuity with a digital ventral support.

  The length of the plate used is 35 cm and width 15 cm approximately.

  At 13 cm from the top of it, is made a slot (8) of 11 cm which allows the passage of four fingers. The slot (8) is made with a cutter at the level of the joint -3-metacarpophalangeal.

  Laterally the dorsal forearm flap, are secured by two rivets, two Velcro velvet straps (5 and 6). In opposition to these, is attached a strip of Velcro adhesive hook (7). The ventral digital support must be folded upward to form the lateral wings (9).

  Feature of making the second part forming the thumb insertion clip.

  It is made in the same thermoformable low temperature.

  The length of the plate used is 4 cm and width 3 cm.

  Its formatting is done by folding at right angles.

  This clip is fixed by dry heat bonding or by a powerful adhesive preferably in (b and b ') at the height of the nail pallet.

  Achievement characteristic of the third party receiving the thumb. It forms a gutter (3) that follows the initial shape of the thumb.

  The length of the plate used is 20 cm and width 6 cm approximately.

  At the level of the nail pallet, a downward folding (2) is performed which follows the shape of the insertion clip (1) to form the claw clip (2).

  The latter and the insertion clip (1) make it possible to fix the thumb and to relax the posture if necessary.

  The gutter is articulated on the wrist by a rivet (4).

  Execution characteristic of the fourth part which positions the other four fingers. It is composed of three soft non-elastic cotton fabric blades (10). These are fixed at the end of orthosis by a rivet. At each end a small Velcro velvet band (14) is sewn. The Velcro adhesive hook band (15) is positioned on the front of the wrist. On each of the fabric blades (10) slides an ergonomic foam pad called digital separator (13).

  The devices according to the invention are particularly intended for the establishment of an orthosis of the hand without there being tugging, and at the same time, allow to release a prolonged posture without removing the orthosis and allow a interdigital posture of the index, middle finger, ring finger, and little finger. This is for people with a spastic hand, perhaps used in rheumatology. The design concept for the simple antispasticity orthosis, which is a variant, is based on the same methodological principle of manufacture. Only the three soft non-elastic fabric blades, and the pads are removed (see fig: 2/2).

Claims (5)

  1) Antispastic orthosis intended to facilitate the placement of the fingers of the hand and to release a prolonged posture without removing the orthosis, and thus avoid increasing spasticity, pain and inflammatory phenomena by the tightness of the joints; characterized by a dorsal forearm flap in continuity with a ventral digital support, the forearm flap laterally features two Velcro velvet straps (5 and 6), in opposition to these a Velcro tape adhesive hook (7) then another at wrist height (15), one thumb joint being made by a rivet (4) on the dorsal forearm flap at wrist height, with a gutter (3), the combination an insertion clip (1) and a claw clip (2) forming the point of attachment of the thumb and releasing the posture.   2) Device according to claim 1 characterized in that the ventral digital support further comprises three tissue blades (10) fixed by a rivet and each provided with Velcro velvet (14), on which slides an ergonomic pad (13). ).   3) Device according to claim 2 characterized in that the ergonomic pad is sponge foam (13) and slides on each of the flexible fabric blades (10).   4) Device according to claim 3 characterized in that the holding in opposition of the thumb and relaxation of the posture can be done by the thermoformed insertion clip 20 (1) and the claw attachment (2).   5) Device according to claim 4 characterized in that the clip claw (2) is an integral part of the thumb positioning channel and is thermoformed.
