The Patent Description & Claims data below is from USPTO Patent Application 20060048269, Functional glove for the hand of a disabled person.





[0001] The present invention relates to a functional glove for the hand of a disabled person.

BACKGROUND OF THE INVENTION

[0002] Quadriplegia compromises manual functionality by reducing the number of motor operations, which are usually required in common activities of everyday life for self-management and for interaction with the microenvironment that surrounds the patient.

[0003] Manual disability entails assistance of the patient even for meeting the most basic needs, from personal hygiene to feeding to graphical communication to pushing the wheelchair in all the various transfers.

[0004] The severity of manual disability has always promoted research aimed at giving back at least partially to the patient this basic gestural expressiveness.

[0005] Highly diversified solutions have thus been obtained which range from the construction of small aids which facilitate manual motor operations to important technologies which propose to animate the hand by means of functional electrical stimulation systems.

[0006] The described aids substantially comprise all the commonly used objects to which a particular diversified shape has been given (in order to facilitate their grip even if the patient is unable to close his fist) or which are provided with receptacles in which one or more fingers or the entire hand are accommodated. In practice, the hand and the tool are coupled artificially (i.e., without using the normal grip of the hand).

[0007] The hypothetical case of functional electrical stimulation instead entails implanting a plurality of electrodes at the muscle surface in the motor points; said electrodes are driven by a stimulator (which also can be optionally implanted). By way of the presence of a sensor for detecting motion, generally of the shoulder of the injured limb, the simulator provides an electrical signal to the electrodes: for example, a retraction of the shoulder can be interpreted by the stimulator as the command to close the fist.

[0008] None of these solutions is easily accepted and used by the patient for various reasons, such as the slowness of the motor operation induced by the aid or the management complexity of the tool (especially in the case of neuroprostheses with electrical stimulation).

[0009] The patient in fact needs the manual gesture to be performed even inaccurately but in time with his motor requirements. For this reason, many solutions which are scientifically interesting are not requested and used by the patient in practice.

SUMMARY OF THE INVENTION

[0010] The aim of the present invention is to obviate the cited drawbacks and meet the mentioned requirements, by providing a functional glove for the hand of a disabled person by way of which it is possible to prearrange the hand of the patient in order to facilitate the handling of various objects.

[0011] An object of the present invention is to mass-produce the glove according to the invention, since it can be adapted to any possible disability of the patient.

[0012] Another object of the present invention is to provide a glove whose shape and dimensions are similar to those of gloves used for normal sports applications, and which therefore does not have the appearance of an auxiliary apparatus for handicapped individuals and is therefore similar to the gloves normally used by the disabled to make it easier for them to push the wheelchair.

[0013] Within this aim, another object of the present invention is to provide a structure which is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.

[0014] This aim and this object are achieved by the present functional glove for the hand of a disabled person, characterized in that it comprises at least one optionally flexible restraint for at least one of the fingers of the hand, and removable fastening means for rigid fixing to the wrist, said glove being worn over the hand by the disabled person during use.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Further characteristics and advantages will become better apparent from the following detailed description of a preferred but not exclusive embodiment of a functional glove for the hand of a disabled person, illustrated by way of non-limiting example in the accompanying drawings, wherein:

[0016] FIG. 1 is a plan view of a glove according to the invention, worn on a hand;

[0017] FIG. 2 is a plan view of a glove according to the invention in the open configuration, with the wrist free.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] With reference to the figures, the reference numeral 1 generally designates a functional glove for the hand of a disabled person.

[0019] The functional glove 1 is suitable to be fitted over the hand 2, leaving free the tips of the fingers 3, and is then fixed firmly to the wrist 4 by means of a fastening strip 5 made of a hook and loop-fastener known as Velcro.RTM..

[0020] The glove comprises a substantially elastic splint 6, which is arranged on the lateral surface of the glove 1, starting from the wrist 4, along with the lateral surface of the short adductor 7 of the thumb 8, up to the upper portion of the thumb 8. The splint 6 can be fixed directly by sewing it on to the glove 1 (or can be rigidly coupled with other similar solutions), but it is also possible to provide a hollow seat (formed by stitching a flap of fabric onto the glove 1, forming a pocket), in which the splint 6 is inserted. The splint 6 is locked to the wrist because its end that is aligned with said wrist is accommodated below the strip of Velcro 5.

[0021] The presence of the splint 6 ensures that the thumb 8 of the hand 2 of the disabled person maintains an active position, because the splint 6 is substantially uncurved, i.e. straight and therefore forces alignment between the wrist 4 and the portion of the thumb 8 to which it is fixed: positioning the splint 6 on one side or the other of the wrist 4 allows to arrange the thumb 8 in opposition to the other fingers 3 (in order to allow easier grip) or align it with them (for example to push the wheelchair easily).

[0022] An ellipsoidal body 9 is fitted on the back of the glove 1, on the proximal and distal part of the metacarpal phalangeal articulations of the first four fingers 3, and is anchored by means of an annular structure (not shown in the figure) to the palm portion of the glove 1.

[0023] The portion 9a of the ring 9, when the glove is fitted, is located on the proximal part of the metacarpal phalangeal articulation, while portion 9b lies above the distal part: the articulation is comprised within the ring 9.

[0024] The ends 9c and 9d of the ring 9 are fixed adjustably to the annular structure that is provided on the palm portion: by adjusting the length of this fixing, it is possible to force the ring 9 more or less strongly onto the hand 2, changing the opening angle of the metacarpal phalangeal articulation and preparing the hand 2 of the disabled patient in a position that facilitates grip.

[0025] Each receptacle for the fingers 3 has, at its end, at least one sort of small noose 10, which is rigidly coupled to a respective bridle 11, which can slide on the back of the glove 1 and has an adjustable length.

[0026] In practice, each bridle 11 surrounds, with the respective end noose 10, a receptacle for a finger 3 of the glove 1 at the phalangeal articulation, and its opposite end is rigidly coupled to the Velcro strip 5 and is therefore rigidly coupled to the wrist 4 by fastening it.

[0027] The optimum execution of a glove 1 according to the invention provides for a pair of nooses 10 for each finger 3, each noose being connected to a respective bridle 11: the bridle 11 that leads to a first noose 10 preferably slides within the glove 1 over the back of the hand 2, and the other bridle 11, which leads to the second noose 10 (arranged opposite the first one), slides inside the glove 1 below the palm of the hand 2. By pulling the finger 3 with one bridle 11 or the other, it is possible to determine the most suitable position thereof.

[0028] The elastic splint 6, the ellipsoidal body 9 and the bridles 11 are provided simultaneously on the glove 1: their use or action can be simultaneous or separate (independently of each other) depending on the requirements of the patient.

[0029] In order to facilitate the insertion of the hand 2, the glove 1 is made of a material whose internal surface has high surface sliding properties.

[0030] The operation of the invention is intuitive: once the glove 1 has been put on, the thumb 8 of the patient is kept in a partially open position or in opposition to the other fingers 3 (depending on the position for fixing to the wrist 4 and on the elastic action performed by the splint 6) as a consequence of the presence of the splint 6. The four fingers 3, which a disabled person normally tends to keep with their metacarpal phalangeal articulation hyperextended, are kept in a partially bent position with respect to the palm of the hand 2 as a consequence of the presence of the ring 9: the angle at which the metacarpal phalangeal articulation is arranged depends on the extent to which the ends 9c and 9d are fastened to the annular structure that lies on the palm portion of the glove 1.

[0031] Each finger 3, considered individually, is kept in a preset position by the respective bridles 11, being surrounded by the nooses 10 and kept under traction as a consequence of the fixing of the opposite end of the bridles 11 to the Velcro band 5. This prevents the patient, as a consequence of involuntary movements, from closing a finger 3 onto the palm of the hand 2, hindering grip.

[0032] It should be noted that disabled patients normally wear gloves such as the ones used by cyclists in order to improve friction between the hand 2 and the respective wheel of the wheelchair: wearing a functional glove 1 according to the invention therefore does not entail any psychological burden for the patient, since the glove 1 is shaped in a manner which is substantially similar to a cycling glove.

[0033] Optional alternative embodiments may allow at least one of the aids (splint 6, ring 9 and bridles 11) to be removable if the patient does not require their action, and it is likewise possible to provide a glove 1 that has only one or two of these aids.

[0034] It has thus been shown that the invention achieves the proposed aim and objects.

[0035] The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

[0036] All the details may further be replaced with other technically equivalent ones.

[0037] In the embodiments shown, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other embodiments.

[0038] Moreover, it is noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.

[0039] The embodiment of the present invention shall be carried out in the most scrupulous compliance with the statutory and regulatory provisions related to the products of the invention or correlated thereto and following any required authorization of the corresponding competent authorities, with particular reference to regulations related to safety, environmental pollution and health.

[0040] In practice, the materials used, as well as the shapes and dimensions, may be any according to requirements without thereby abandoning the scope of the protection of the appended claims.

[0041] The disclosures in Italian Patent Application No. BO2004A000528 from which this application claims priority are incorporated herein by reference.
