Definitions
- the present invention is related to those that try to provide support to the upper extremities for certain activities such as handling, either through the use of the mouse and/or keyboard, cell phones and in general electronic devices and their peripherals such as some game controls.
- joysticks by their name in English) among others to collaborate to avoid or reduce the discomfort of carpal tunnel syndrome caused by different causes, the most common being the repetition of the movement of the hand and because the horizontal axis of the hand is altered. this in the support with the surface due to carpal tunnel syndrome;
- the invention works by eminently mechanical means, which is why it is considered an invention in this area of knowledge.
- Carpal tunnel syndrome is pain caused by inflammation and pressure inside the tunnel formed by the carpus and the transverse carpal ligament in the wrist, where various tendons and the median nerve are located. It is a very common focal peripheral neuropathy, frequent in women (7:1) between 40 and 60 years old and related to occupation. It affects more than five million Americans.
- Nerve compression may be due to tenosynovitis, lunate joint dislocation, viciously consolidated fractures (Colles), sprains or arthritis, continuous use of the wrist in flexion for a long time.
- Other causal factors may be Rheumatoid Arthritis, diabetes, work stress and the repeated use of vibrating hand tools, among others.
- the treatment of this pain begins with the application of splints at night, anti-inflammatories to relieve pain and numbness.
- a corticosteroid injection may also be used to reduce inflammation. It is essential that the doll remain in a neutral position, that is, one that allows the horizontal axis of the hand to be preserved (with the wrist joint straight and not down). If symptoms are severe or do not improve with the aforementioned treatment, conventional or endoscopic surgical intervention is recommended. Other available alternatives are ultrasound and laser.
- portable palm rest for computer wrists refers to the manufacture of a portable palm rest for computer wrists, which can be used in both hands, which belongs to the sector of products intended to protect the user from the inconveniences and consequences that arise from continuous use of the computer. It is composed of a band-bra that has the peculiarity of holding an anatomically shaped pad, which quickly adapts to the palm of the hand and wrist, and whose function is to protect them from the pain, numbness, discomfort and cumulative injuries generated by all of them. them due to the continuous use of the computer (mouse and keyboard).
- the portable palm rest for wrists has a lightweight, functional and economical aesthetic appearance that does not present any discomfort and can be used by all workers who interact with a machine or computer for a long time, in which the keyboard and mouse are the mediating references.
- the fastening elements 6 and 8 trap the user's extremities with complex elements that end up causing a variety of complications, for example.
- the poor position of the hand on the pad allows the pain to now be transferred to other parts of the hand, such as the edges and those points where the elevation has been caused;
- This mobility of the pad could be a problem at another point;
- fastening mechanisms that have clasps or buttons could cause lacerations where these structures make contact with the hands and the point where they are placed.
- the apparatus can apply a force dorsally directed toward the region of the pisiform bone in the neutral carpal position of a human hand upon co-contraction of the hand and up to 2.98 kg (8 pounds) dorsally directed during the arc of motion in carpal flexion, as the wrist and hand are stimulated to move actively in all planes of motion without restricting the range of motion or negatively affecting normal activities of daily living.
- the apparatus may comprise a tension structure for applying dorsally directed force and a base structure for maintaining the tension structure in its proper configuration during normal hand movement.
- ES2185877 which involves a wrist support for treating carpal tunnel syndrome and discloses a wrist splint for carpal tunnel syndrome (100) consisting of an outer liner (10) having a primer (51) and a second (52) trimmed with numerous eyelets (12), both edges being connected to each other by a tab (20) sewn between them.
- the outer liner contains a thumb hole (11) to receive the thumb (2) and is shaped to adapt to the patient's wrist so that the patient can insert the hand and wrist into the proximal end (14) of the outer liner and extend four fingers to the distal end (15) of the outer liner with the thumb inserted in the hole of thumb, then the outer lining is fixed to the patient's wrist to activate the immobilization of the wrist using a pair of pins with clasps and knots (32,33) and a set of laces (30), its configuration is quite complex to being able to place it with just one hand, because the user's other hand is simply immobilized to be able to place the invention.
- ES2765482T3 which consists of a band to compress or support a joint that specifically is a support or compression device configured to surround a limb or a joint of a user, comprising an elastic band (1) that has two band segments (10 , 20) that have different rigidity values, the elastic band that has an internal face (15) in contact with an area covered by the band and an external face (14) opposite to the internal face, the internal face of the band provides , in the presence of a compressive pressure exerted by the band when tightened under tension around a limb or joint, an adhesion with the covered area, so that the band locally retains elongations resulting from different tensile forces, after removal of traction forces.
- a glove (20) designed to inhibit or prevent carpal tunnel syndrome is described that includes a flexible glove body (22), which has a front side (24) and a rear side (26), the glove assembly defining a first opening wrist (28) and at least one finger opening (30).
- the glove assembly (20) also includes a resilient protector (32), fixed to the front side (24) of the glove body (22), to prevent the application of pressure to a median nerve.
- the flexible protector (32) defines a recess (36) that extends essentially parallel to both sides (38) of the median nerve. It is also interrupted along its extension, which provides greater flexibility and facilitates movement for the person wearing the glove set. (twenty). Also described is a grip that includes a flexible shield interrupted along its length.
- the invention particularly focuses on those people who require support for the heel of the palm of the hand to maintain a horizontal position, due to a previous injury who ordinarily have a scar due to having been operated on for Tunnel Syndrome.
- Figure 1 is a front view of the ergonomic cushion with elastic band for wrist and heel support of the hand, which prevents or reduces carpal tunnel injury.
- Figure 2 is a rear view of the ergonomic cushion with elastic band for wrist and heel support of the hand, which prevents or reduces carpal tunnel injury.
- Figure 3 is a side view, the other side view being substantially the same, of the ergonomic cushion with elastic band for wrist and heel support of the hand, which prevents or reduces carpal tunnel injury.
- Figure 4 is a top view of the ergonomic cushion with elastic band for wrist and heel support of the hand, which prevents or reduces carpal tunnel injury. In this image you can see both the part that supports the wrist and the part that supports the heel of the hand; These elements being the most representative of the invention and therefore attend to both essential parts so that Carpal Tunnel Syndrome can be avoided or reduced.
- Figure 5 is a bottom view of the ergonomic cushion with elastic band for wrist and heel support of the hand, which prevents or reduces carpal tunnel injury.
- Figure 6 is a conventional perspective view of the ergonomic cushion with elastic band for wrist and heel support of the hand, which prevents or reduces carpal tunnel injury.
- Figure 7 is a view simulating the placement in a user's hand of the ergonomic cushion with elastic band to support the wrist and heel of the hand, which prevents or reduces carpal tunnel injury. This figure shows that the invention causes the position of the hand to maintain the horizontal axis.
- the ergonomic cushion with elastic band for wrist and heel support of the hand which prevents or reduces carpal tunnel injury, comprises an elastic band 1 transversely attached to a pad 2 with some fastening means 3 (preferably seams) in such a way that it is prevented from separating between them, but additionally the pad 2, by means of projections 3 that form a single piece with it, covers the joining points 4 with the band 1;
- the pad 2 comprises at least two sections, where a first section A is precisely arranged under the carpal bones of the hand, providing conventional padded support; preferably the filling of the pad 2 is made of low-density polyurethane-type material; a second section B is positioned under the so-called “wrist of the hand” which is the area of union between the carpal bones and the phalanges of the fingers and which, being preferably joined with at least one seam 5 that joins them and forms the C bulges (from a lateral view) which in addition to positioning the carpal bones, also allows the hollow of the hand to be
- Sections A and B can be subsectioned to create different points of contact with the hand, which are coupled to the different heights that, thanks to the synergy with the seams 5, allow the pad to comprise a plurality of sections that maintain different heights in the bulges C that adapt to the position of the hand.
- a first variant consists of placing seeds such as birdseed, rice, chia, cilantro, flaxseed, lentils, sesame, sesame or a multiplicity of them in some of the sections, either mixed in the same cavity or arranged in different sections. , which allow sweating to be eliminated from the wrist and heel of the palm of the hand and additionally adapt to the whimsical shapes of the palms of the hands; Any combination of said seeds can additionally be interspersed with polyurethane or materials that allow the different sections of the pad to be padded.
- the secondary sections A and B that are attached to the pad 2 with the seams C can be used folded towards the side sections of the pad 2, in such a way that if they are not required, they can be folded and stored under the hand, and remain placed in that position thanks to the elasticity of the band 1 until the user wishes to use them on the different parts of the hand.
