The present invention generally relates to devices for alleviation and or prevention of carpal tunnel syndrome. More particularly, the present invention is in the technical field of Wrist Cushion devices for people who routinely engage in activities that involve repetitive movements of the hand and wrist such as with a computer keyboard in combination with and not limited to a computer mouse.
Prolonged use of primarily computer devices such as a mouse or keyboard for an extensive period of time can cause repetitive restriction in a persons wrist which could lead to various stages or carpal tunnel syndrome.
Carpal tunnel syndrome occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist. The median nerve controls sensations to the palm side of the thumb and fingers (although not the little finger), as well as impulses to some small muscles in the hand that allow the fingers and thumb to move. The carpal tunnel—a narrow, rigid passageway of ligament and bones at the base of the hand—houses the median nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the median nerve to be compressed. The result may be pain, weakness, or numbness in the hand and wrist, radiating up the arm.
Primarily most conventional wrist cushion devices, such as those made with similar materials used in bean bags and some have gel filled supports and memory type foam usually attached to a mouse pad or an isolated device are usually stationary.
It is in most cases, products that support the wrist for ergonomic reasons where the devises are stationary which are not efficient and can cause discomfort and other types of medical issues. One of the most popular devices is used with the mouse and a second for use with a keyboard. As a stationary device the bean bag type of material is the most common but it very restrictive and causes limited movement which can cause a great deal of discomfort and not be very effective. This not being a convenient way for any user since the computer devices mentioned above require continuous movement when using the products. It is common to continuously lift ones hand off the pad and place down again to hit certain keys that can add stress to the wrists and arms over a prolonged period of time.
Therefore there is a need for a modification to the designs of cushioned wrist supports that allow for fluid movement with ease of use without the need for straps and other types of locking mechanisms. The need for such a device to move freely with little or no friction while remaining secured and parallel to the users wrist is ideal to reduce or prevent carpal tunnel syndrome. The device would be created to be a one size fits all that is made up of simple design and material so it can be supplied to large groups of users in any given office space.
A wearable mouse cushion device that allows the user to move freely and glide across any smooth surface. With little or no friction the device supports their wrists and allows the cushion to remain parallel to the tendons of the arm for which it is to support elevated from the surface.
A method to lock a users wrist into the device is done with out straps or rope or any connection similar to Velcro but with resistance from foam which extends beyond the plastic casing.
To achieve a user to be locked into the device the top edge of the casing has an extension of foam with a plastic tab inside for resistance and to keep the foam formed in the same location over periods of time of use. This allows the foam to bend to the pressure of a users wrist pressing down and through it's thickness as it passes through, then regaining form back into it's original position preventing the wrist to move in a reverse direction in which it is locked into the device.
The users in order to release their wrists from the device would simply apply the same amount of force upward while holding the device to enable the wrist to pass through spreading the foam with the tabs open as the wrist become clear from the device. The same process applies for each wrist. Naturally with the surface acting as an opposite force pressing down requires no assistance from each of the users other hand. When lifting up naturally a resistance needs to keep the device in place so the wrist may be released from the device.
Another method unlike most or all other devices of similar uses, this device allows a user to insert their wrist within the device either palms down as explained above or their wrist rotated ninety degrees clockwise for the right hand and then turn counter clockwise to be engaged for use of the device. This is a preferred method to utilize the device since their would be far less friction and wear on the foam materials which would lead to a longer life of the product. As far as from a design point the various sizes of mens and womens wrists would allow this method to use a one size fits all for better design and longevity of the product. This method will be preferred and show in the figures below.
The accompanying drawings illustrate the aspect of the present invention.
A wearable wrist cushion device that allows for maximum mobility and sufficient support for use by typists, computer users and others susceptible or at risk of suffering from repetitive strain injury. Other medical diagnosed injuries associated with prolonged use of a computer mouse and keyboard is carpal tunnel syndrome.
The wearable wrist cushion support device
The sizing of the device will be designed for at least two sizes but not limited to two different sizes. Since the circumference of womens and mens wrist vary greatly as well as users of teenagers there is a greater need to accommodate the supply and demand for variety in sizes. The design of the product is not one size fits all at this time and needs to be able to comfortably be used by users who's wrists vary from five to nine inches in circumference.
Referring to the invention in more detail, in
The material for the wrists to be supported on plastic casing 11 is to manufactured by injection molding of PVC or a similar plastic material. The cushion material would also be manufactured by a similar or same method by injection molding with a material that gives the proper support to a users wrist and has the resilience of lasting over a long period of time with out wear down or tearing but not limited to the lifespan of the product within normal usage and normal computer use conditions.
