BACKGROUND1. Field
This disclosure relates to medical devices for the digits of athletes.
1. Description of the Related Art
Football, basketball, volleyball, rugby, water polo, soccer, hockey, baseball, softball, golf, tennis, racquetball, table tennis, power lifting, boxing, swimming, polo, lacrosse, gymnastics, track and field and other sports are widely played by many people.
Because of the physical nature of sports, finger and toe injuries are common.
Most people have fifteen finger bones in each hand. Referring to
Each of the bones (not shown) within the fingers 120, 130, 140, 150 are connected at the knuckles 122, 132, 142, 152, 124, 134, 144, 154 with ligaments (not shown). Knuckles 122, 132, 142, 152, 124, 134, 144, 154 are susceptible to sprains, strains, dislocations and ligament tears while playing sports.
The term jammed finger refers to an injured finger, due to injuries such as compression, a sprain, a strain, or dislocation of one or more of the joints. Jamming may result following impact with an opponent or teammate, sudden contact with a ball, a fall, or any sudden stretching of a finger 120, 130, 140, 150. Falls onto hard, unyielding surfaces (for example. a basketball floor) may result in jams. It is also common for ligaments to tear near the joints when joints 122, 132, 142, 152, 124, 134, 144, 154 become dislocated.
Common treatments for a jammed finger include taping an injured finger to an adjacent finger or splinting a finger.
Toes may be similarly injured, though the treatment options are typically more limited.
DESCRIPTION OF THE DRAWINGS
Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than limitations on the apparatus and methods disclosed or claimed.
Referring now to
The term sheath refers to a device which at least partially covers and/or supports a finger or toe (i.e., a digit) of a warm blooded vertebrate, having a general geometry of a hollow cylinder such as a sleeve, with either open ends or one open and one closed end. The sheath 820 may have the shape of a thimble, a cylinder a mitt or other geometry.
The sheath 820 may be utilized as a medical device in a variety of sports. The sheath 820 may provide support to one or more digits and/or one or more knuckles during physical activities. By providing support and rigidity to one or more fingers, the sheath 820 may protect a person's finger from further injury.
The sheath 820 may be formed of a flexible sheet of material, for example, spandex. Spandex is lightweight, durable, soft smooth, supple, and resistant to body oils, perspiration, lotions, and detergents. Moreover, spandex has sufficient flexibility to take the form of a finger when stretched. Because spandex is not very strong, the sheath 820 may be formed by wrapping several layers around the middle finger 820. Additionally, the density of the spandex may be customized to provide a stiffness that prevents the first knuckle from bending. Thus, the spandex may be manufactured such that only a single wrap or layer may be needed to provide desired stiffness to at least partially immobilize a portion of a finger.
Additional materials may be selected based on one or more of density, rigidity and modulus of elasticity. For example, the sheath 830 may include leather, vinyl, cotton, neoprene or other material.
Because people have different size fingers, the sheath 820 may be customized for each person. An example of customizing the sheath 820 is manufacturing the sheath according to ring sizes. Another example of customizing the sheath 820 is providing the sheath 820 in the form of a two sided tape. The term tape refers to a rolled up strip of long, thin anti narrow material. One side of the tape may include an adhesive or fastener, such as a hook and look type fastener. The other side of the tape may include frictional elements 830, disposed on the outside of the middle finger 140, analogous to the features of one or more of a football, a basketball, a volleyball, a rugby ball, a water polo ball, a soccer ball or other sporting device. In order to fully customize the sheath 820, the frictional elements 830 may be spaced along the sheath 820 such that one side of the finger includes frictional elements 830 and the other side of the sheath 820 provides a surface for attachment.
Examples of frictional elements include integrated bumps, dots, ridges, irregularities, granular elements to match a sporting good, and other elements. The frictional elements 830 may be incorporated into the sheath 820 during manufacturing or added manually by an athlete. If the sheath 820 has a relatively high coefficient of friction, then an athlete may grip a ball, a stick, a person, or another object with greater ease than with bare fingers. For example, the frictional surface may include small bumps, hooks, protrusions, suction cups or other features that provide for high friction. Each frictional element may 830 be sized, shaped, positioned and characterized (e.g., its stickiness) to complement the object to be controlled. For example, an array of dots may be used as in U.S. Pat. No. 5,500,956, the disclosure of which is incorporated herein by reference, particularly the disclosures regarding frictional elements 830 and gloves as they may be combined with or used in the medical devices disclosed herein.

The term tongue refers to a projecting section of material which extends from a body. The term body refers to the main or structural portion of a device. The term aperture refers to a an opening or open space, such as a hole, gap, cleft, chasm or slit.
The sheath 200 may be manufactured as a unitary device, for example via injection molding, extrusion, weaving, stitching or other process. In turn, the sheath 200 may be adapted to fit a single finger or multiple fingers (as shown in the plan view of a hand 100 in
The characteristics of the sheath 200 may be selected based upon the object to be gripped, and how the fingers are to move. Such objects include basketballs, footballs, baseballs, rugby balls, baseball bats, hockey sticks, golf clubs, tennis racquets and table tennis paddles. For example, in sports which include bats or sticks, at least one knuckle may need to bend in order to control the sporting device whereas the other knuckle can be immobilized and protected.
The strength and weight of the sheath 200 may be determined based on the material that it is manufactured from. Appropriate materials include a plastic, a woven fabric, an elastomer, a rubber, a paper based material, a metal or combinations of materials. The sheath 200 may include a fabric soaked in a resin, which, when removed from a hermetically sealed package and unraveled onto a finger, cures into a firm covering, such as a mold or cast. The sheath 200 may be an elastomer, such as latex, that unravels onto a plurality of fingers.
Examples of polymers include synthetic resins and organic resins. Organic resins may be thermoplastic, which may aid in the spinning, crimping, shaping and bonding of component sections by thermal processes. Examples of organic resins include hydrocarbon resins such as vinyl, polyvinyl chloride (PVC), polyethylene, polyamides, polyesters, polypropylene or other material. Polymers are inexpensive to manufacture and therefore may be produced for one time usage.
The sheath 200 may be woven from a soft fabric, such as cotton, but may also have some sections which are firm. Stiffness may be varied by section by manufacturing a material which has a greater thickness in a given section or a greater density in a given section. For example, the sheath 200 may include a dense spandex for covering a knuckle, and a less dense cotton to cover the balance of a finger. Thus, the knuckle may be immobilized whereas the balance of the finger is aesthetically dressed. For some professional athletes, a custom device may be produced in order to last several games.
Additionally, to provide support to an athlete's injured finger, a section of the sheath 200 associated with an injured knuckle or digit of the injured finger may include a support, such as one or more hard plastic or metal strips or rods (not shown). The support may be selectively attached to the sheath 200 such that an injured athlete may add additional support as needed.
Physical sports generally result in sweating. Thus, bacteria, mold, fungus and other undesirable microorganisms may attempt to grow on the sheath 200. In order to retard growth of the undesirable microorganisms, the material of which the sheath 200 manufactured may include or be treated with one or more anti-fungal or anti-bacterial agents.
An example of a chemical that acts both as an anti-bacterial and an anti-fungal agent is an oxy-substituted aromatic arsine such as oxybisphenoxarsine (OBPA). The oxysubstituted aromatic arsine, such as OBPA, is a bacteriostat, disinfectant and fungicide. OBPA prevents the growth of microorganisms when compounded in resins and also acts as a preservative. OBPA can be formulated as an emulsifiable concentrate, pelleted, tableted, soluble concentrate/liquid and ready-to-use liquid. OBPA may be incorporated into a polymer or cloth of which the sheath 200 is formed.
Some sports are played in cold weather environments, such as skiing, snowboarding, ice hockey, football and other sports. In cold weather, if a finger is relatively immobilized, it may be difficult to generate heat and the finger may become numbingly cold. In order to aid the player in maintaining heat with the finger, the sheath 200 may include ferrous or other material that oxidizes rapidly. If the sheath 200 is provided in an air tight seal and then the seal is broken, the ferrous material may oxidize creating heat. This embodiment would be applicable to a one time use. However, a miniature heating coil may be embedded in the material of the sheath 200 that can be activated via a pressure switch, a small battery or other system.
Additionally, when injuries first occur, a health care professional may recommend cooling of the injured area. Thus, the sheath 200 may be stored in a cooler or frozen prior to sports play. At the time of injury, the sheath 200 may be applied and provide dual function, that of an ice pack and that of support.
The body 205 of the sheath 200 may have a geometry that fits over a knuckle and at least a portion of adjacent digits of a finger to the knuckle (not shown). The body 205 may be sufficiently rigid such that an injured knuckle does not flex when a person attempts to flex the finger. Thus, the body 205 may prevent bending about the knuckle of a finger and allow for healing.
The body 205 may define a first opening 260 disposed proximate the bottom of the sheath 200, a second opening 250 disposed proximate the top of the sheath 250 and an aperture 220 disposed along a side of the sheath 200. The aperture 220 may be disposed towards the bottom of the side, the top of the side, the middle of the side, the majority of the length of the side or other configuration. The size of the aperture 220 may be based upon the size of a person's fingertip or other dimension. A person may stretch or slide the first opening 260 over the tip of a finger (not shown) and then down the finger towards the base of a finger. Another embodiment of the body 205 (not shown) does not include the second opening 250 but has a closed tip. This embodiment may be suited for cold weather sports in order to maintain heat in the finger tip.
The aperture 220 may have geometry and dimensions based the size of a person's fingertip or other dimension. For example, if a person is able to insert a fingertip into the aperture 220, the person can to pull the sheath 200 down across the finger. Additionally, the aperture 220 may provide for breathing of skin and reduction in moisture buildup. An additional embodiment (not shown) includes a plurality of dispersed small apertures to promote cooling and air flow. This embodiment may be selected for sports played in the warm weather and/or when the sheath 200 is worn for a prolonged period of time.
When the sheath 200 is in place on a person's finger, the person's finger tip may be exposed beyond the second opening 250. In some sports, such as basketball, exposed fingers allow the athlete to better control a ball, as an athlete's fingertips are touch sensitive. In this embodiment, the sheath may not extend beyond the midpoint of the second digit of a finger or the first digit of the thumb in order to maintain finger—ball contact.
The outer surface 210 of the sheath 200 may include a high coefficient of friction and/or frictional elements. The outer surface 210 may include an attachment device or fastener to aid in attaching the sheath 200 to another sheath (not shown). Examples of attachment devices include loop fasteners, adhesives, snaps, zippers, slips, combinations herein or other fasteners.
In order to fasten to another sheath (not shown), the tongue 230 may include a first surface 235 which includes hooks that interlock with loops on the another sheath's outer surface (not shown). The first surface of the tongue 235 may include an adhesive or a magnetic material which secures the tongue 235 to the another sheath.
The tongue 230 may have a length that allows the athlete to wrap the tongue 230 around two or more sheaths (not shown) thereby securing the sheath 200 to other sheaths (not shown). An additional embodiment may utilize an elastic band (not shown) integral to the body 205 to wrap around and secure the sheath 200 to adjacent sheaths (not shown).
Attachment features may be disposed along the body 205 and/or the tongue 230. Attachment features may be disposed proximate the adjacent sections of the sheath of one finger to the sheath of the adjacent finger.
As shown in
Interference fits are characterized by a diametral interference of approximately 0.001 to 0.002 units per unit of depression diameter. Friction fits are characterized by diametral interference of less than approximately 0.001 to 0.002 units per unit of depression diameter.
In order to maintain an interference fit and/or a friction fit, the protrusion 240 and the depression 245 may be manufactured with a low coefficient of elasticity. In turn, the protrusion and the depression 245 may not easily deform or separate. Hard polymers, dense fabrics, metals and other materials may provide these properties.
The inner surface 270 may include an attachment device. For example, if the body 205 is formed by a material that is able to be rolled, but not bent axially, the body 205 may be formed by a sheet including one or more attachment devices. In fact, the inner surface 270 may include an adhesive to secure the body 205 to a person's finger.
The body 205 may be directionally flexible and/or directionally rigid depending on the type of sport the athlete is playing. For example, in sports like lacrosse or hockey, a person holds a stick with the fingers curved around the stick. If the person's second knuckle is injured, it may be necessary to immobilize the second knuckle, but allow the first knuckle to bend. However, due to swelling, the injured finger may have a swelling about the injury that is up to approximately two times the circumference of the adjacent digit. Therefore, the body 205 may need to stretch axially and radially while being applied to the injured finger and then provide bending rigidity about the injured section. Moreover, based on the sport, the body 205 may be adapted to provide bending rigidity along the whole finger, one portion of the finger, or multiple portions of the finger. When holding a bat or stick, the person may desire a single knuckle maintained in a straight set with the other knuckle having the ability to bend. When playing a game such as basketball, the entire finger may be restrained from bending. The amount of bending and where bending may or may not occur may be determined by a sports physician, a physical therapist, a professional trainer, a nurse, first aid provider, an emergency services provider or other heath care professional.
Directional rigidity may be provided by incorporating axially aligned metal fibers, carbon fibers or other materials in conjunction with a polymer and/or fabric. Such metallic components may allow for magnetic properties. Examples of metallic components include wood, metal or composite wires, rods or strips, metal powder loaded polymers, metal fiber loaded polymers and other components.
Additionally, a customized set of two, three, four or five sheaths 200 may be temporarily or permanently fixed to or inside of a baseball glove, a football glove, a golf glove, a soccer goalie glove, a rugby glove, a volleyball glove, a wrestling glove, a weight lifting glove, a track and field glove, a water polo glove, a hockey glove or other glove (not shown).
Referring now to
The first sheath 310 includes an outer surface 315 and a tongue 330. The tongue 330 includes a first surface 335. The second sheath 320 includes an outer surface 325. The first surface 335 of the tongue 330 may be adapted to secure the first sheath 310 to the second sheath 320. For example, the first surface 335 of the tongue 330 may include an adhesive.
If the first sheath 310 is secured to the second sheath 320, then an injured pinky finger 120 may be immobilized relative the first digit of the ring finger 130. By securing the first sheath 310 to the second sheath 320, additional strength and control may be exercised in various maneuvers. For example, when a basketball athlete attempts to gain control of a basketball via a rebound, if the ball hits a tip of the pinky finger 120, the first sheath 310 and the second sheath 320 may provide strength amongst the pinky finger 120 and the ring finger 130 and distribute the impact among the pinky finger 120 and the ring finger 130 and not further injure the pinky finger 120.

In the embodiment of
Referring now to
The first finger sheath 510, the second finger sheath 520 and the third finger sheath 530 may respectively include ridges 515, 525, 535 in the outer surfaces. The first finger sheath 510, the second finger sheath 520 and the third finger sheath 530 may be attached to each other via a band 540. The band 540 may wrap around the finger sheaths 510, 520, 530 and interlock with the ridges 515, 525, 535 in order to prevent the finger sheaths 510, 520, 530 from moving relative to each other. Additionally, the band 540 may be elastic member to fit tightly around the finger sheaths 510, 520, 530. In turn, the finger sheaths 510, 520, 530 and the band 540 provide protection to the first knuckles of the pinky, ring and middle fingers from jams or other injuries.
Referring now to
The first finger sheath 510, the second finger sheath 520 and the third finger sheath 530 may respectively include axial depressions 515, 525, 535 in the outer surfaces. The first finger sheath 510, the second finger sheath 520 and the third finger sheath 530 may be attached to each other via a strip 600. The strip 600 may include ridges which interlock with the axial depressions 515, 525, 535 in order to prevent the finger sheaths 510, 520, 530 from moving relative to each other. Moreover, the strip 600 may include an adhesive and/or magnetic material to provide additional binding to the finger sheaths 510, 520, 530 such that the strip 600 may be disposed only on the portion of the finger sheaths 510, 520, 530 toward the back 110 of the hand 100. Therefore, the strip 600 need not contact a ball when an athlete handles a ball.
Referring now to
Because the sheath 700 secures the second knuckle of the index finger 150 and the second knuckle of the middle finger 140 relative one another, injury to second knuckles may be prevented. The outer surface 710 may include small suction cups or sticky dots to aid in the handling of a sports ball such as a football. For example, a wide receiver may be able to catch a pass easier with the sheath 700.
Additionally, by securing one or more sheaths to one or more other sheaths in a relatively fixed position, a predetermined angle may be set for optimum performance. For example, if the digits of the fingers are set in a general “C” geometry, an athlete may have an advantage while managing a lacrosse stick (not shown). If the digits of the fingers are set in a general “(” geometry, an athlete may have an advantage while passing a football (not shown).
Additionally, by securing one or more sheaths to one or more other sheaths in a generally planar geometry, a martial arts practitioner may have an advantage when striking an opponent or an object due to the rigidity amongst the sheaths (not shown).
Detachability and re-attachability may also provide other benefits. This includes replacement of worn sheaths. Also, an athlete can change the appearance of their sheath by replacing one or more sheaths with one appearance (e.g., color) with sheaths of a different appearance. Moreover, the sheath may include an appealing fragrance or deodorant which may increase demand among feminine athletes and/or athletes who are offended by the smell of dried sweat.
Another benefit of detachability (and re-attachability) is the ability to conform to varying rules. That is, some rules may allow an open tipped sheath whereas some sports may allow only a closed tipped sheath (not shown). Additionally, some rules may allow for the sheaths to be attached to one another, whereas others may require the sheaths not to attach to one another.
Moreover, rules may permit or prohibit friction enhancing features in varying locations.
The relative position of various parts of the sheath 200 is described based upon the view of
Although shown implemented with fingers, the apparatus may be implemented with human toes, and/or fingers and toes of warm blooded vertebrate pets.
