Patent Description:
Unfortunately, accidents or other medical conditions can impact the flexion and/or extension of a finger's interphalangeal joints. For example, when a tendon used to extend a finger becomes torn while another tendon used to pull the finger toward the palm of the hand remains intact, the finger can become contracted against the palm. Treatment of such an injured finger can involve bracing the finger into a desired position while the finger heals. Some devices have been developed that use screws to move parts into place to brace an injured finger. However, conventional devices fail to achieve sufficed magnitude of force or rigidity on the finger.

<CIT> describes an adjustable finger splint having a metacarpophalangeal (MCP) platform, a frame and a slide, wherein the MCP platform and the frame define a cavity to receive a finger and the slide can move relative to the MCP platform and the frame.

The present disclosure relates to an adjustable finger splint providing improved adjustability.

This disclosure includes systems and implementations for providing an adjustable finger splint usable to treat various finger related injuries. For example, age, injury, or damage to one or more of the figures may cause the fingers to stiffen or lock in a bent or flexed position. For instance, damage or injury to the extensor tendons or ligaments in the finger often cause the finger to lock in a bent or flexed position due to force exerted by the flexor tendons on the finger. In this instance, if the injury remains untreated the finger may remain permanently in a flexed position. However, conventional treatments including casting the finger locks the finger in an extended position for long periods of time. Therefore, the adjustable finger splint discussed herein provides for a splint that allows the user to remove the finger from the splint when the user's pain threshold is elapsed as well as for the user to self-adjust the amount of pressure applied by the splint at any time during use, thereby, allowing the injury to be treated without the need for continuous casting or long recovery times due to surgery.

In some cases, the adjustable finger splint may include a self-contained unit or may be formed as an assembly of two or more separate components. The adjustable finger splint may include a main body that may be permanently or releasably coupled to a slide. The main body may have a front end positioned away from the user during use and a rear end, opposite the front end, or positioned proximate to the user during use. The main body may also include an opening or cavity configured to receive a finger of the user and to hold the finger in place during treatment or use. When the finger is secured within the opening, the user's finger may be positioned such that the end of the user's finger is proximate the front end and the palm of the user is proximate the rear end.

A slide may be movable, adjustable, or slidable relative to the main body of the finger splint, and, thus movable, adjustable, or slidable relative to the injured finger held immobile by the main body. In these cases, the slide may be used to increase or decrease the pressure applied to the end of the finger by adjusting the position of the slide relative to the main body. In some implementations, the slide has a wedge that is configured to apply increasing pressure on the end of the finger held within the main body as the slide is pushed or pulled outwards towards the front end of the main body. In this manner, as the slide is moved away from the body of the user, a curvature of the wedge forces the finger further and further toward a fully extended position. Thus, in some examples, the user may gradually reduce the angle of the injured finger relative to the hand (e.g., further straighten the finger) over a period of treatment (e.g., days, weeks, or months depending on the severity of the injury).

In some implementations, the slide may be releasably coupled to the main body, such that the slide may be removed or separated from the main body when not in use and, thus, allow for the adjustable finger splint to be more easily stored or carried. In alternative implementations, the finger splint may be configured to prevent loss of the independent components of the splint and, thus while the palm side may be movable or adjustable with respect to the main body, the slide may be affixed, such as via a track, to the main body. In these alternative implementations, the slide and the main body may be inseparable. In some cases, the slide and/or the main body may be formed form a substantially rigid material, such as various plastics, polymers, metals, alloys, polyurethanes, gases, fluids, gels, foams, fibers, or combinations thereof.

As discussed above, the adjustable finger splint may include two or more substantially rigid components that apply pressure to an injured finger in a manner to hold the finger in a straighten or extended position. However, in some situations, direct contact between the substantially rigid material of the main body and slide of the splint may result in pain levels that exceeds the tolerance thresholds of the individual being treated, even for a short duration. Thus, the adjustable finger splint may also include a dorsal pad and a palmar pad to increase comfort and reduce pain caused by the finger splint to the user when in use. In some cases, the palmar pad may be secured to the slide below the hand of the user and the dorsal pad may be secured along a bottom of a top surface of the opening within the main body of the adjustable finger splint in a position above the finger. In some cases, either or both of the dorsal pad and the palmar pad may be formed from a material, such as polyurethanes, elastomers, etc..

In some cases, injury to one or more fingers may be caused by age or be one of numerous injuries stained by the user. In these cases, the user may be unable to apply necessary force to the slide to cause the injured finger to extend. Thus, in some implementations, the adjustable finger splint may be designed, such that a third-party (e.g., physical therapist, hand therapist, doctor, surgeon, nurse, or other medical professional) is able to adjust the slide relative to the main body. In these implementations, the slide may include a pull or handle proximate to the front end that the third-party may use to adjust the slide relative to the main body. The main body may also include a grip or other stabilizing portion that the third-party may utilize to substantially maintain the position of the main body when adjusting the position of the slide. In one particular implementation, the main body may be weighted such that when the adjustable finger splint is set or rests on a table or other surface, the main body preserves its position as the palm side is moved.

In some cases, the finger splint may also be configured to allow the user or other medical professional to measure the angle of the finger relative to the hand of the user both at rest and during use of the splint. For instance, in some implementations, the adjustable finger splint may include a window such that the user or the medical professional may utilize a protractor or other tool to measure the relative angles between the finger and hand. In other implementations, the protractor may be built into the splint, such as printed along the window, or the main body may include an extended portion that may mirror the position of the finger within the opening of the main body. In still other implementations, the adjustable finger splint may include a dial that may be turned to adjust the position of the slide relative to the main body and also provide or determine the relative angle of the finger and hand.

<FIG> depicts an embodiment of an adjustable finger splint <NUM>. The adjustable finger splint <NUM> may comprise a main body <NUM>, a slide <NUM>, a dorsal pad <NUM>, and a palmar pad <NUM>, as discussed above. As illustrated, the finger splint <NUM> may include a front <NUM> and a back <NUM>. In the illustrated example, the front <NUM> is positioned away from the user during use and the back <NUM>, opposite the front <NUM>, is positioned proximate to or facing the body of the user during use.

As discussed above, the main body may also include an opening or cavity, generally indicated by <NUM>, configured to receive a finger of the user during treatment or use. When the finger is secured within the finger opening <NUM>, the user's finger may be resting on the palmar pad <NUM>, such that the end of the user's finger is proximate the front <NUM> and the palm of the user is proximate the back <NUM>. The user may then push on a back end <NUM> of the slide <NUM>, to cause the slide <NUM> to move in a direction towards the front <NUM> of the splint <NUM>. As the palmar pad <NUM> is flexible, the inserted finger may force the palmar pad <NUM> downward such that it bends down to rest atop the slide <NUM>. The slide <NUM> may push the palmar pad <NUM> and the finger of the user upwards as the slide <NUM> is moved towards the front <NUM>. As the palmar pad <NUM> and the finger are extended upward the finger may contact the dorsal pad <NUM>. The dorsal pad <NUM> and the main body <NUM> apply pressure in opposite directions (e.g., upward and downward respectively) on the finger causing the finger to extend and straighten. As the position of the slide <NUM> relative to the main body <NUM> may be moved or adjusted to increase or decrease the pressure applied to the end of the finger, the user may set the pressure load based on the discomfort that the user is experiencing (e.g., by increasing the pressure, the effect of the treatment is increased but so is the discomfort).

In the illustrated example, both the main body <NUM> and the slide <NUM> are substantially rigid, such that the splint <NUM> may apply opposing pressure on a finger placed within the finger opening <NUM> of the main body <NUM>. However, in some situations, direct contact between the substantially rigid material of the main body <NUM> and slide <NUM> may result in increased pain levels that exceeds the tolerance thresholds of the individual being treated, even for a short duration. Thus, in the illustrated implementation, the adjustable finger splint <NUM> may also include the dorsal pad <NUM> and the palmar pad <NUM> to increase comfort and reduce pain caused by the finger splint <NUM> during use. It should be understood that in other implementations, the dorsal pad <NUM> and the palmar pad <NUM> may be optional or removable. For instance, the dorsal pad <NUM> and/or the palmar pad <NUM> may wear out or occasionally need to be replaced. In these instances, by including a removable dorsal pad <NUM> and palmar pad <NUM>, the entire splint <NUM> does not have to be discarded when the pads <NUM> and <NUM> are worn out. In some situations, the thickness and/length of either or both of the dorsal pad <NUM> or the palmar pad <NUM> may be adjusted or custom sized to fit the intended user. In these situations, by including removable dorsal pads <NUM> and palmar pads <NUM>, the main body <NUM> and the slide <NUM> may be stock to reduce manufacturing costs of the splint <NUM>.

<FIG> depicts an example left side view of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the illustrated example, the finger splint <NUM> again includes two rigid or hard component, the main body <NUM> and the slide <NUM>, as well as two pads, the dorsal pad <NUM> and the palmar pad <NUM>. In this example, a finger of a user may be placed between the dorsal pad <NUM> and the palmar pad <NUM>, such that the finger of the user rests on the front portion of the palmar pad <NUM>(A) and the palm of the user rests on the rear portion of the palmar pad <NUM>(B) during use. In this implementation, the main body <NUM> includes a metacarpophalangeal (MCP) platform <NUM> that is configured to support the rear portion of the palmar pad <NUM>(B) and, thereby, maintain the palm of the user in a fixed position during use. A frame <NUM> extends upward from the MCP platform <NUM>. The frame <NUM> may be configured to support a PIP platform (not shown) over the finger of the user when the splint <NUM> is in use. The PIP platform may be configured to couple to the Dorsal pad <NUM> and maintain the Dorsal pad <NUM> above the finger being treated. In the illustrated example, the MCP platform <NUM> may be integral to the frame <NUM>, however, in some implementations the MCP platform <NUM> and/or frame <NUM> may be configured to decouple from each other, such that different sized MCP platforms <NUM> and/or frames <NUM> may be selected based on the specific finger, anatomical measurements of the injured hand, the characteristics associated with the palmar pad <NUM> (such as thickness of the padding, material type, number of layers, etc.), and/or the characteristics of the associated with the dorsal pad <NUM> (e.g., as thickness of the padding, material type, number of layers, etc.).

In the current example, the main body <NUM> may have a slide platform <NUM> extending between walls of the frame <NUM>. The slide platform <NUM> may support the slide <NUM> during use and include a top surface (not shown) that is included at a predetermined angle relative <NUM> to the MCP platform <NUM>. The relative angle of the incline of the slide platform <NUM> to the MCP platform <NUM> causes the slide <NUM> to engage the palmar pad <NUM> in a manner that lifts the front end of the palmar pad <NUM> at an angle complementary to the relative angle <NUM> between the MCP platform <NUM> and the slide platform <NUM>, as discussed below with respect to <FIG> in more detail.

<FIG> depicts an example right side view of the adjustable finger splint <NUM> with the palm side <NUM> in initial or loose position of <FIG> according to some implementations. In this example, once the user's hand is engaged with the splint <NUM> (e.g., the palm of the user is resting on the rear portion of the palmar pad <NUM>(B) and the finger being treated is resting on the front portion of the palmar pad <NUM>(A)), the user may apply forward pressure, generally indicated by arrows <NUM>, on the slide <NUM> by pushing on the back end <NUM> of the slide <NUM> to cause the slide <NUM> to move forward (e.g., toward the front end <NUM> of the splint <NUM>) and, thereby, raising the front portion of the palmar pad <NUM>(A) upwards, as illustrated below with respect to <FIG>.

In the illustated example, the main body <NUM> may also include a window <NUM>. The window <NUM> may allow the user and/or a medical professional to view the position or angle of the finger during treatment. For example, the user and/or a medical professional may utilize a tool (e.g., a protractor) to measure the relative angle of the finger during treatment and, thereby, gage a level of affect or improvement (e.g., relative straightening of the finger) experienced by the user. In some cases, the window <NUM> may include markings (e.g., degrees) that may be used to measure the relative angle of the finger without the use of additional tools.

<FIG> depicts an example right side view of the adjustable finger splint <NUM> of <FIG> with slide <NUM> in an engaged position according to some implementations. As discussed above with respect to <FIG>, the user may apply forward pressure <NUM> on the back end <NUM> of the slide <NUM> to cause the slide <NUM> to engage with the front portion of the palmar pad <NUM>(A). As illustrated when the slide <NUM> is engaged with the front end of the palmar pad <NUM>(A), the front end of the palmar pad <NUM>(A) is raised upward toward the dorsal pad <NUM>. Thus, in the engaged position, the dorsal pad <NUM> applies a downward or stabling pressure on the proximal phalanx and the front end of the palmar pad <NUM>(A) applies an opposite upward pressure on the distal phalanx (or the end of the finger), causing the finger to extend as the MCP j oint and the PIP j oint are straightened. By maintaining force on the j oint at maximum extension, the contracted tissues are elongated and mobility is restored. However, by allowing the user to apply the pressure <NUM> to the slide <NUM>, the user is able to control the amount of time spent applying the treatment and, in some situations, to remove the hand from the splint <NUM>, allowing the user use of the hand and a break from the treatment.

As discussed above, the main body <NUM> may include a slide platform <NUM> that has an incline that is at a predetermined angle (not shown) relative to the MCP platform <NUM>. The relative angle of the incline of the slide platform <NUM> to the MCP platform <NUM> causes the slide <NUM> to engage the palmar pad <NUM> in a manner that lifts the front end of the palmar pad <NUM>(A) at an angle complementary to the relative angle between the MCP platform <NUM> and the slide platform <NUM>. In the current example, the slide <NUM> also has a wedge <NUM> positioned proximate to a front end <NUM> of the slide <NUM>. The wedge <NUM> has a curvature that is configured to cause the finger to straighten as the slide <NUM> is pushed towards the front end <NUM>. Thus, in the illustrated implementation, the finger of the user is forced into the extended position in part due to the relative angle between the incline of the top surface of the slide platform <NUM> and the MCP platform and in part based on the curvature of the wedge <NUM>. The radius of the curvature of the wedge <NUM> is calibrated to maintain the DIP joint in a neutral position throughout the range of extension of the slide <NUM>.

In the illustated example, the main body <NUM> may also include a measuring device <NUM>. As discussed above, the splint <NUM> may include a window to allow the user and/or a medical professional to view the position or angle of the finger during treatment. In this example, the splint <NUM> may include a measuring device <NUM> that may indicate the angle or straightness of the finger being treated. For example, the measuring device <NUM> may be mechanically coupled to a component that is adjusted based on contact or position of the slide <NUM>. In this example, the measuring device <NUM> may rotate to provide an indication of the angle or straightness of the finger being treated as the slide <NUM> is adjusted. It should be understood that in other examples, the measuring device <NUM> may take other forms.

<FIG> depicts an example rear view of the adjustable finger splint <NUM> of <FIG> according to some implementations. As discussed above, the main body <NUM> includes a frame <NUM> that supports a PIP platform <NUM>. The frame <NUM> and the PIP platform <NUM> of the main body <NUM> forms a finger opening <NUM> to receive a finger of the user as discussed above. In the illustrated example, the dorsal pad <NUM> may be secured or adhered to the PIP platform <NUM> and the palmar pad <NUM> may be secured or adhered to the MCP platform <NUM> as shown. For example, various types of adhesive may be used to affix the dorsal pad <NUM> to the underside of the PIP platform <NUM> and the palmar pad <NUM> to the top surface of the MCP platform <NUM>.

In the illustrated example, the back end <NUM> of the finger splint <NUM> may be textured or patterned to allow for increased friction when the user pushes or applies pressure to the back end <NUM> of the slide <NUM>. It should be understood, that the finger splint <NUM> may be operated by the user with one hand. For example, the user may grip a front (not shown) of the MCP platform <NUM> using healthy fingers, generally at locations <NUM> and/or <NUM>, while engaging the back end <NUM> of the slide <NUM> using the thumb.

<FIG> depicts another example rear view of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, the dorsal pad <NUM> and the palmar pad <NUM> have been removed from the main body <NUM>. In some situations, the pads <NUM> and/or <NUM> may wear at a faster rate than the main body <NUM> and/or the slide <NUM> or the thickness of the dorsal pad <NUM> and/or the palmar pad <NUM> may be selected or adjusted based on the needs of the individual being treated. For instance, some individuals may have hands thinner than others. These individuals may require the use of larger dorsal pads <NUM> and/or palmar pads <NUM>. Thus, such as in the illustrated example, in some implementations, the dorsal pad <NUM> and/or the palmar pad <NUM> may releasably couple to the main body <NUM>.

In the current example, the dorsal pad <NUM> may include one or more coupling components <NUM> that extend upwards from a top surface <NUM> of the body of the dorsal pad <NUM>, such that the coupling components <NUM> may be received by corresponding receptacles (not shown) over the finger opening <NUM> along a bottom surface <NUM> of the PIP platform <NUM>. In some implementations, the dorsal pad <NUM> may include two coupling components, such as left coupling components <NUM>(A) and right coupling components <NUM>(B). In some examples, the coupling components <NUM> may include a locking or mating member that may secure the dorsal pad <NUM> to the main body <NUM>. In some implementations, such as the illustrated example, the dorsal pad <NUM> may be secured by friction between the coupling components <NUM> and the corresponding receptacles within the bottom surface <NUM> of the PIP platform <NUM>. In some implementations, the bottom surface of the dorsal pad <NUM> may be contoured to receive the top surface of the finger of the user to provide increased comfort. In some implementations the dorsal pad <NUM> may be coupled in a manner that allows its position to be adjusted for the fit and comfort of the user, as will be discussed in more detail below.

The palmar pad <NUM> may also include one or more coupling components <NUM> that extend downward from a bottom surface <NUM> of the body of the palmar pad <NUM>. For example, the MCP platform <NUM> may include a receptacle <NUM> for receiving the coupling component <NUM>. In this example, the receptacle <NUM> may open to the back <NUM> of the MCP platform <NUM> such that the coupling component <NUM> may be pushed or slide into the receptacle <NUM> from the back <NUM> of the splint <NUM>. In some instances, the receptacle <NUM> may extend along at least a portion of the MCP platform <NUM>, such that the front of the coupling component <NUM> abuts a back surface (not shown) of the receptacle <NUM> to resist forward movement caused by pressure on the back end <NUM> of the slide <NUM> and maintain the palmar pad <NUM> on the MCP platform <NUM>. In these examples, the coupling component <NUM> and receptacle <NUM> may have corresponding angled walls such that the coupling component <NUM> may resist upward movement caused by pressure of the slide <NUM> on the front end of the palmar pad <NUM>, as discussed above.

<FIG> depicts an example front view of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, the slide <NUM> is at rest or has not been engaged with the palmar pad <NUM>. In this example, the main body <NUM> includes the finger opening <NUM> to receive the finger of the user prior to engaging the slide <NUM> with the palmar pad <NUM>. In the illustrated implementation, a front of the MCP platform <NUM> is visible. In this illustrated implementation and as discussed above, the user may place one or more healthy fingers at locations <NUM> and <NUM> to provide apply a backwards pressure when the user pushes the slide <NUM> forward. In some cases, the locations <NUM> and <NUM> may include a texture or grip that provides increased frictions and allows the user to more easily apply the backwards pressure on the MCP platform <NUM>.

<FIG> depicts an example top view of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, the dorsal pad <NUM> and the palmar pad <NUM> are in place and the slide <NUM> is currently in the at rest position. As shown, the back portion of the palmar pad <NUM>(A) may cover the surface of the MCP platform <NUM> and the palmar pad <NUM> may then extend through and out of the main body <NUM>, as illustrated by the front end of the palmar pad <NUM>(A). As the palmar pad <NUM> is formed from a flexible material the front end of the palmar pad <NUM>(A) may flex upwards when in contract with the slide <NUM>.

The dorsal pad <NUM> is secured to the bottom surface or underside of the PIP platform <NUM>. In the current example, the dorsal pad <NUM> may extend past a front or rear edge of the PIP platform <NUM> to allow the user or other individual to pinch and remove the dorsal pad <NUM> from the main body <NUM> by pulling downward on the dorsal pad <NUM>.

<FIG> depicts an example bottom view of the adjustable finger splint <NUM> of <FIG> according to some implementations. As illustrated, the slide <NUM> is resting on the slide platform <NUM>. As discussed above, the slide platform <NUM> has a top surface (e.g., the surface in contact with the slide <NUM> and not shown) that includes an incline at a predetermine angle relative to the MCP platform <NUM>.

<FIG> depicts an example top view <NUM>, side view <NUM>, and bottom view <NUM> of the slide <NUM> of <FIG> according to some implementations. As discussed above, in some implementations, the slide <NUM> may be releasably coupled to the main body <NUM> of <FIG>, such that the slide <NUM> may be removed or separated from the main body <NUM> when not in use and, thus, allow for the adjustable finger splint <NUM> to be more easily stored or carried. In the illustrated example, the slide <NUM> includes a slide rail <NUM> and a wedge <NUM> having a predefined curvature <NUM>. The curvature <NUM> of the wedge <NUM> causes the finger to gradually extend or straighten as the slide <NUM> is moved in a direction towards the front end <NUM> of the splint <NUM>. The curvature <NUM> having a radius of between approximately <NUM> centimeters (cm) and <NUM>. In one particular example, the radius of the curvature <NUM> may be <NUM>.

The wedge <NUM> also includes a lip or edge <NUM> that forms a groove or recessed portion <NUM> along either side of the wedge <NUM>. The main body may include two locking members that may be received into the recessed portion <NUM> via an opening <NUM> on either side of the slide <NUM>. In some examples, the slide <NUM> may be coupled with the main body <NUM> by placing the locking members into the recessed portion <NUM>. Then when the palmar pad <NUM> may be coupled to the main body <NUM> over the slide <NUM>, such that the palmar pad <NUM> prevents the slide <NUM> from decoupling from the main body <NUM>. In this manner, the slide <NUM> is less likely to decouple or become lost.

In some implementations, the length (e.g., the distance between a back end <NUM> and a front end <NUM>) of the slide <NUM> may be between approximately <NUM> and <NUM>. In one particular example, the length of the slide <NUM> may be <NUM>. The wedge <NUM> may also have a length that is between one-third and one-fourth the length of the slide <NUM> and the slide rail <NUM> may have length between two-third and three-fourths of the length of the slide <NUM>. For example, the wedge <NUM> may be between <NUM> and <NUM> long and the slide rail <NUM> may be between <NUM> and <NUM>. In one particular example, the wedge <NUM> may have a length of <NUM> and the slide rail may have a length of <NUM>. The slide rail <NUM> may also have a height of between approximately <NUM> and <NUM> and a width between approximately <NUM> and <NUM>. The wedge <NUM> may have a height of between approximately <NUM> and <NUM> and a width between approximately <NUM> and <NUM>. In some cases, the width of the slide rail <NUM> and the wedge <NUM> may be the same or equal to the size of the slide opening <NUM> in the main body <NUM>, as discussed below with respect to <FIG>.

In some examples, the slide <NUM> may be formed as a single component or unit. The slide <NUM> may be formed from a rigid material, such as various plastics, polymers, polyethylene terephthalate, among others. In some cases, the slide <NUM> may have a shore D average hardness rating of between approximately <NUM> and <NUM>.

In the current example, the slide <NUM> is illustrated as removed from the main body <NUM>. However, it should be understood in other alternative implementations, the finger splint <NUM> may be configured to prevent loss of the independent components of the splint <NUM> and, thus the palm side <NUM> may be movable or adjustable with respect to the main body <NUM> but affixed (e.g., via a track) to the main body <NUM>, such that the splint <NUM> is a single unit.

<FIG> depicts an example back perspective view of the main body <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. As discussed above, the main body <NUM> includes a MCP platform <NUM> for providing support for both the palmar pad (not shown) and a palm of the user (not shown), a frame <NUM> that supports both a PIP platform <NUM> and the slide platform <NUM> at opposite ends. For instance, the PIP platform <NUM> is position above a top surface <NUM> of the MCP platform <NUM> and the slide platform <NUM> is positioned below a bottom surface of the MCP platform <NUM>.

The frame <NUM> may form a continuous opening between the PIP platform <NUM> and the slide platform <NUM> from the front of the main body <NUM>. However, the continuous opening may be divided into two segments from the back of the main body <NUM> by the MCP platform <NUM>. The two segments of the continuous opening include the finger opening <NUM> for receiving the finger and a slide opening <NUM> for receiving the slide <NUM> of <FIG>. Thus, in the illustrated implementation, the slide opening <NUM> may receive or be occupied the slide <NUM> during use.

The MCP platform <NUM> may include one or more receptacles, such as a receptacle <NUM> configured to mate or lock with the palmar pad <NUM> of <FIG>. The receptacle <NUM> may be between approximately <NUM> and <NUM> long, <NUM> and <NUM> wide, and <NUM> and <NUM> deep. The receptacle <NUM> may also be narrow along the top and wider along the bottom such that the side walls are angled or flanged outward from top to bottom. The flanged walls prevent the palmar pad <NUM> from dislodging during use as the slide <NUM> pushes upward on the front end of the palmar pad <NUM>(A). The receptacle <NUM> is also open at the top surface such that the palmar pad <NUM> may include a coupling component that may mate with the receptacle <NUM> and is integral with the body of the palmar pad <NUM>, as discussed in more detail below. In some cases, the flange walls may be at an angle of between approximately <NUM> and <NUM> degrees. The frame <NUM> may also include grooves, generally indicated by <NUM>(A) and <NUM>(B), that may mate with the front portion of the palmar pad <NUM>. The frame <NUM> may have an overhang that defines the grooves <NUM>. The overhangs may also act to resist upward movement of the palmar pad <NUM> when the slide <NUM> is engaged. The grooves <NUM> may also help resist any forward movement of the palmar pad <NUM>.

The PIP platform <NUM> includes a bottom surface that also includes one or more receptacles, such as receptacles <NUM>(A) and <NUM>(B). The receptacles <NUM> may run the full length of the PIP platform <NUM> or may only run a partial length of the PIP platform <NUM>. For instance, the receptacles <NUM> may be between approximately <NUM> and <NUM> long, <NUM> and <NUM> wide, and <NUM> and <NUM> deep. In some cases, the length of the receptacles <NUM> may be longer than the length of the coupling components of the dorsal pad <NUM> such that the dorsal pad <NUM> may be able to slide or adjust as the slide <NUM> is engaged with the palmar pad <NUM>, as will be discussed in more detail below.

The slide platform <NUM> may include a top surface <NUM> that is at an incline relative to the top surface <NUM> of the MCP platform <NUM>. In some cases, the include may be at an angle of between approximately <NUM> and <NUM> degrees. The incline of the top surface <NUM> causes the slide <NUM> to impact the front end of the palmar pad <NUM>(A) at an angle that gradually extends or straightens the finger through zero degrees of flexion and into the range of hyperextension.

In some examples, the main body <NUM> may be formed as a single component or unit. The main body <NUM> may be formed from a rigid material, such as various plastics, polymers, polyethylene terephthalate, among others. In some cases, the main body <NUM> may have a hardness rating of between approximately shore D average hardness rating of between approximately <NUM> and <NUM>.

<FIG> depicts an example partial-front-partial-bottom view of the main body <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the illustrated example, the receptacles <NUM>(A) and <NUM>(B) for receiving the coupling components of the dorsal pad <NUM> (not shown) are visible along the bottom surface of the PIP platform <NUM>. The frame <NUM> may also support slide locking members, generally indicated by <NUM>(A) and <NUM>(B), within the space of the continues opening <NUM>. As discussed above, the opening <NUM> is continuous along the lengths of the main body <NUM> from the front but divided between the finger opening <NUM> and the slide opening <NUM> from the back by the MCP platform <NUM>. Thus, from the current partial-front view of the main body <NUM>, the opening <NUM> runs the full length between the PIP platform <NUM> and the slide platform <NUM> as shown.

<FIG> depicts an example back view of the main body <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current illustration, the continuous opening <NUM> is defined by the frame <NUM>, the slide platform <NUM>, and the PIP platform <NUM> and is divided into two segments, finger opening <NUM> and the slide opening <NUM> by the MCP platform <NUM>. In the current implementation, the continuous opening <NUM> may be between approximately <NUM> and <NUM> tall and <NUM> and <NUM> wide. Similarly, the finger opening <NUM> may be between approximately <NUM> and <NUM> tall and <NUM> and <NUM> wide and the slide opening <NUM> may be between approximately <NUM> and <NUM> tall and <NUM> and <NUM> wide. In one particular example, continuous opening <NUM> may be approximately <NUM> tall and <NUM> wide, the finger opening <NUM> may be approximately <NUM> tall and <NUM>. <NUM> wide, and the slide opening <NUM> may be approximately <NUM> tall and <NUM> wide.

In some cases, the frame <NUM> may be between approximately <NUM> and <NUM> long or tall and vary between approximately <NUM> and <NUM> wide. The PIP platform <NUM> may be between approximately <NUM> and <NUM> wide and <NUM> and <NUM> deep. The PIP platform <NUM> may also have a thickness of between approximately <NUM> and <NUM>. Similarly, the slide platform <NUM> may be between approximately <NUM> and <NUM> wide and <NUM> and <NUM> deep. The slide platform <NUM> may also have a thickness of between approximately <NUM> and <NUM>.

<FIG> depicts an example top view of the main body <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current illustration, the PIP platform <NUM> and the MCP platform <NUM> are visible. As the slide platform <NUM> extends past the back edge of the PIP platform <NUM>, a portion of the slide platform <NUM> is also visible. In the current example, the slide locking members <NUM> are also visible. The slide locking members <NUM> may be configured to lock or mate with the recessed portion <NUM> of the slide <NUM> (not shown) via the opening <NUM> in the bottom portion of the wedge <NUM>. For instance, the slide <NUM> may be first placed through the slide opening <NUM> from the back of the main body <NUM>. The wedge <NUM> of the slide <NUM> may then be positioned above the slide locking members <NUM> to align the opening <NUM> with the slide locking members <NUM>. Next, the slide <NUM> may be lowered such the slide locking members <NUM> are received by the recessed portion <NUM> of the slide <NUM>. The slide <NUM> may then adjust with respect to the main body <NUM> as the slide locking members <NUM> move within the recessed portion <NUM> relative to the main body <NUM>. In some cases, the palmar pad <NUM> (not shown) is then placed over the MCP platform <NUM> by mating the coupling component of the palmar pad <NUM> with the receptacle <NUM>. When in place the palmar pad <NUM> blocks or prevents the slide <NUM> from decoupling from the slide locking members <NUM> and, thus, from decoupling from the main body <NUM>.

From the illustrated example, it should be understood that the width of the MCP platform <NUM> is wider than the width of the PIP platform <NUM>. In some cases, the width of the MCP platform <NUM> may be between approximately <NUM> and <NUM> and the length of the MCP platform <NUM> may be between approximately <NUM> and <NUM>. The MCP platform <NUM> may also have a thickness that varies from back to front. For example, the thickness at the back of the MCP platform <NUM> may be between approximately <NUM> and <NUM> and the thickness at the front of the MCP platform <NUM> may be between approximately <NUM> and <NUM>.

<FIG> depicts an example bottom view of the main body <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current illustration, the slide platform <NUM> and the MCP platform <NUM> are visible. As the PIP platform <NUM> extends past the front edge of the slide platform <NUM>, a portion of the PIP platform <NUM> is also visible. In the current example, the slide locking members <NUM> are also visible. As discussed above, the slide locking members <NUM> may be configured to lock or mate with the recessed portion <NUM> of the slide <NUM> (not shown) via the opening <NUM> in the bottom portion of the wedge <NUM>. The receptacles <NUM>(A) and <NUM>(B) for receiving the coupling components of the dorsal pad <NUM> (not shown) are also visible. In some cases, the receptacles <NUM> may be approximately <NUM> from the edge front edge of the main body <NUM>, approximately <NUM> from the back edge of the main body <NUM>, and approximately <NUM> from either side wall of the frame <NUM> of the main body <NUM>.

<FIG> depicts an example side view of a two-part main body <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the above examples, the MCP platform <NUM> and the frame <NUM> may be integrally coupled or formed as a single component. However, in some cases, the MCP platform <NUM> may be formed as a separate component from the frame <NUM> and configured to releasably couple to the frame <NUM>. For example, the palm of a specific user may be usually small or large and require a different sized MCP platform <NUM> for support. Alternatively, the user's finger may be too large to fit through the opening in the frame <NUM> while the MCP platform <NUM> is attached. In these examples, the MCP platform <NUM> may be selected to fit the individual user and then coupled to the frame <NUM>. In the current example, the frame <NUM> may include male connector components <NUM> and the MCP platform <NUM> includes female connector components. However, it should be understood that, in some implementations, the MCP platform <NUM> may include the male connectors and the frame <NUM> may include the female connectors.

<FIG> depicts an example bottom view <NUM> and a side view <NUM> of the dorsal pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, the dorsal pad <NUM> includes two coupling components <NUM>(A) and <NUM>(B) for securing the dorsal pad <NUM> to the PIP platform <NUM> of the main body <NUM> (not shown) of the splint <NUM>. In other implementations, the PIP platform <NUM> may include any number of coupling components <NUM>, such as one or three coupling components.

The dorsal pad <NUM> may be between approximately <NUM> and <NUM> tall, <NUM> and <NUM> wide, and <NUM> and <NUM> deep. In one particular example, the dorsal pad <NUM> may be approximately <NUM> tall (not including the extension of the coupling components <NUM>), <NUM> wide, and <NUM> and <NUM> deep. In some cases, the coupling components <NUM> may be less than the full depth of the dorsal pad <NUM> as illustrated. In these cases, the coupling components <NUM> may be between approximately <NUM> and <NUM> tall, <NUM> and <NUM> wide, and <NUM> and <NUM> deep. The coupling components <NUM> may also be shorter than the receptacles <NUM> of the PIP platform <NUM> on the main body <NUM> (not shown), such that the dorsal pad <NUM> may slide or move relative to the main body <NUM> and, thereby, adjust for comfort of the user. In some cases, the dorsal pad <NUM> may be formed from a material, such as various plastics, polyurethanes, rubbers, foams, or other material. In some cases, the dorsal pad <NUM> may have having a shore A hardness of between approximately 80A and 90A.

<FIG> depicts an example bottom view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. As discussed above, the palmar pad <NUM> includes a front portion <NUM>(A) and a back portion <NUM>(B). The front portion <NUM>(A) may be configured to flex when impacted by the slide <NUM> (not shown). In various implementing, the back portion <NUM>(A) may be wider than the front portion <NUM>(A) and configured to support the palm of the user. For example, the back portion <NUM>(B) may be between approximately <NUM> and <NUM> deep and <NUM> and <NUM> wide and the front portion <NUM>(A) may be between approximately <NUM> and <NUM> deep and <NUM> and <NUM> wide. Thus, the palmar pad <NUM> may be between approximately <NUM> and <NUM> deep. In another example, the palmar pad <NUM> may be between approximately <NUM> and <NUM> deep.

In the current example, the front portion <NUM>(A) and the back portion <NUM>(B) of the palmar pad <NUM> may be formed form the same material. However, in other examples, the front portion <NUM>(A) and the back portion <NUM>(B) of the palmar pad <NUM> may be formed from different materials. For instance, the material of the front portion <NUM>(A) may be less rigid than the material of the back portion <NUM>(B). In some cases, the palmar pad <NUM> may be formed from a material, such as various plastics, elastomers, polyurethanes, rubbers, foams, or other material. In some cases, the palmar pad <NUM> may have having a shore A hardness of between approximately 80A and 98A.

In the illustrated example, the palmar pad <NUM> also includes coupling component <NUM> for securing the palmar pad <NUM> to the main body <NUM> of the splint <NUM>. In the current example, the coupling component <NUM> may be between approximately <NUM> and <NUM> tall, <NUM> and <NUM> wide, and <NUM> and <NUM> deep.

In some implementations, the main body <NUM> may also include grooves <NUM> along the frame <NUM>. In these examples, the palmar pad <NUM> may include a mating surfaces <NUM>(A) and <NUM>(B) to contact or be received within the grooves <NUM>. The contact between the mating surfaces <NUM> and the grooves <NUM> together with the coupling component <NUM> may prevent forward motion of the palmar pad <NUM> with respect to the main body <NUM> of the splint <NUM> during use.

<FIG> depicts another example bottom view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. Similar, to the implementation illustrated in <FIG>, the current palmar pad <NUM> includes a front portion <NUM>(A) and a wider back portion <NUM>(B). In the current example, the palmar pad <NUM> also includes multiple coupling components <NUM>. As illustrated, it should be understood that the length and/or width of each of the individual coupling components <NUM> may vary with respect to each other or across implementations.

<FIG> depicts an example side view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, both portions (e.g., the front portion <NUM>(A) and the back portion <NUM>(B)) of the palmar pad <NUM> may be formed from a single material. In this example, the palmar pad <NUM> may have a thickness that may be between approximately <NUM> and <NUM>. In other examples, the thickness of the front portion <NUM>(A) may vary or differ from the thickness of the back portion <NUM>(B). For instance, the front portion <NUM>(A) may be thicker than the back portion <NUM>(B) as the injured finger may require more padding than the palm of the user. As discussed above, the palmar pad <NUM> may also include one or more coupling components, such as coupling component <NUM>.

<FIG> depicts another example side view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In this example, the palmar pad <NUM> may be formed two layers, a top layer <NUM> and a bottom layer <NUM>. For instance, the palmar pad <NUM> may require some rigidity or hardness to prevent the slide <NUM> (not shown) from puncturing or damaging the palmar pad <NUM> when the palmar pad <NUM> is impacted by the wedge <NUM> of the slide <NUM>. At the same time, the palmar pad <NUM> may be configured to provide a desired level of flexibility to reduce pain on the finger when the splint <NUM> is in use. Thus, in the current example, the top layer <NUM> may be formed from a first material and the bottom layer <NUM> may be formed from a second material. In some cases, the second material may be harder than the first material. For example, the first material may be a plastic, polyurethanes, elastomers, or other material having a Shore A hardness between approximately 80A and 90A and the second material may also be a plastic, polyurethanes, elastomers, or other material having a hardness between approximately 90A and 100A.

<FIG> depicts another example perspective view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. As discussed above, the palmar pad <NUM> may be formed from two materials, a more flexible material and a more rigid material. In this example, the rigid material may be formed an interior layer <NUM> that provides support for the back end of the palmar pad <NUM>(B) to provide support for the palm of the user and some rigidity to the overall pad <NUM>. The current example, also includes an exterior layer <NUM> that runs along the top and bottom of the interior layer <NUM> within the back end of the palmar pad <NUM>(A) and forms the entirety of the front end of the palmar pad <NUM>(A). In this example, the interior layer may be formed from the first material and the exterior layer may be formed from the second material.

In the illustrated example, the front end of the palmar pad <NUM>(A) or the finger portion of the palmar pad <NUM> may include notches, generally indicated by <NUM>, along the bottom surface of the pad <NUM>. The notches <NUM> may be used to secure the palmar pad <NUM> to the slide <NUM> and to assist in maintain the palmar pad <NUM> in contact and in a desired alignment with the slide <NUM>. In the current example, the palmar pad <NUM> includes three notches <NUM>, however, it should be understood that any number of notches <NUM> may be implemented. In some cases, the notches <NUM> may also add thickness to the palmar pad <NUM> and increase comfort while maintaining desired flexibility.

<FIG> depicts another example back view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, the palmar pad <NUM> includes two coupling components <NUM> and multiple notches <NUM> for coupling the palmar pad <NUM> to both the main body <NUM> and the slide <NUM> (not shown), as discussed above.

<FIG> depicts another example side view of the palmar pad <NUM> of the adjustable finger splint <NUM> of <FIG> according to some implementations. In the current example, again the palmar pad <NUM> includes an interior layer <NUM> and an exterior layer <NUM>. The notches <NUM> are also shown for coupling the palmar pad <NUM> to the slide <NUM> (not shown).

<FIG> depicts an example perspective view of a main body <NUM> of the adjustable finger splint <NUM> of <FIG> with an adjustable PIP platform <NUM> in a closed position according to some implementations. In some cases, the user's finger may be severely injured or bent. In these cases, the user may be unable to push the finger through the finger opening <NUM> if the PIP platform <NUM> is affixed to the frame <NUM>. Thus, in the illustrated example, the PIP platform <NUM> may be movable between a closed position and an open position.

In the illustrated example, the PIP platform <NUM> may be coupled to the frame <NUM> via hinges, generally indicated by <NUM>, such that the PIP platform <NUM> may open upward from the frame <NUM>. The PIP platform <NUM> may also be locked or held in place via locking platform <NUM>. The locking platform <NUM> may also be coupled to the frame <NUM> via mating component <NUM>. The PIP platform <NUM> may then be released from the closed position by disengaging the locking platform <NUM>, as will be discussed in more detail below with respect to <FIG>.

<FIG> depicts an example perspective view of a main body <NUM> of the adjustable finger splint <NUM> of <FIG> with the adjustable PIP platform <NUM> in an open position according to some implementations. In the current example, the locking platform <NUM> has been pushed up and towards the front end <NUM> of the splint <NUM>, such that the locking platform <NUM> no longer obstructs the opening <NUM>. For instance, when in the closed position, a locking member <NUM> of may extend outward and under the locking platform <NUM> and releasably couple with the mating component <NUM>. For instance, when the locking platform <NUM> is moved downward and towards the front end <NUM> of the splint <NUM>, the locking platform <NUM> prevents the PIP platform <NUM> from moving during use. In one specific example, a bolt couples <NUM> to <NUM> creating a hinged door so the platform <NUM> and dorsal pad (not shown) can be rotated up and away from the finger. A shorter bolt may also couple <NUM> to <NUM> creating a latch. After the finger is placed in the device, the door is closed and the latch may be rotated to couple to the mating component <NUM>.

In the current example, the PIP platform <NUM> is shown as a hinged component, however, it should be understood that in other examples, the PIP platform <NUM> may be configured to slide along a groove in the frame <NUM> between and the open and closed positions. It should also be understood that various other types of locking platforms, mechanisms, or members may be used. In one specific example, the PIP platform <NUM> may be completely removable form the frame <NUM>.

<FIG> depicts an example perspective view of an adjustable finger splint <NUM> usable by a third-party according to some implementations. In some cases, injury to one or more fingers may be caused by age or be one of numerous injuries stained by the user. In these cases, the user may be unable to apply necessary force to the slide <NUM> to cause the injured finger to extend. Thus, in some implementations, the adjustable finger splint <NUM> may be designed, such that a third-party (e.g., physical therapist, hand therapist, doctor, surgeon, nurse, or other medical professional) is able to adjust the slide <NUM> relative to the main body <NUM>. In these implementations, the slide <NUM> may include a pull or handle <NUM> proximate to the front end <NUM> of the slide <NUM>, such that the third-party may use to adjust the slide <NUM> relative to the main body <NUM> by pulling on the handle <NUM>. The main body <NUM> may also include a grip or other stabilizing portion <NUM> that the third-party may utilize to substantially maintain the position of the main body <NUM> when adjusting the position of the slide <NUM>. In one particular implementation, the main body <NUM> may be weighted such that when the adjustable finger splint <NUM> is set or rests on a table or other surface, the main body preserves its position as the palm side is moved.

<FIG> depicts an example side view of the adjustable finger splint <NUM> of <FIG> according to some implementations. As illustated, the handle <NUM> of the slide <NUM> may extend to both the right and left of the wedge <NUM>. Thus, a third-party that is either right or left handed may utilize the handle <NUM>. In some cases, the handle <NUM> may decoupled from the slide <NUM>, such that the slide <NUM> may be placed through the frame <NUM> from the back of the splint <NUM> and then the handle <NUM> may be attached from the front.

<FIG> depicts an example front view and <FIG> depicts an example back view of the adjustable finger splint <NUM> of <FIG> according to some implementations. As discussed above, the slide <NUM> may include the handle <NUM> to assist a third-party individual in operating the finger splint <NUM>. In this example, the handle <NUM> extends to both the right and left of the wedge <NUM>. In the current example, the extensions of the handle <NUM> are less wide than the width of the MCP platform <NUM>. However, in other examples, it should be understood that the length and width of the extensions of the handle <NUM> may vary, for instance, the extensions may extend past the outer edges of the MCP platform <NUM>.

The main body <NUM> also includes a stabilizing portion <NUM> that may be gripped by the third-party individual when pulling on the handle <NUM>. In the current example, the stabilizing portion <NUM> is shown as a rounded handle. But it should be understood, that the stabilizing portion <NUM> may take other forms, such as a gripped handle, weighted portion that may rest on a table or other surface, etc..

<FIG> depicts an example perspective view of the slide of the adjustable finger splint of <FIG> according to some implementations. As discussed above, the slide <NUM> may include the handle <NUM> to assist a third-party individual in operating the finger splint <NUM>. In this example, the handle <NUM> extends to both the right and left of the wedge <NUM>. In the current example, the extensions of the handle <NUM> are less wide than the width of the MCP platform <NUM>. However, in other examples, it should be understood that the length and width of the extensions of the handle <NUM> may vary, for instance, the extensions may extend past the outer edges of the MCP platform <NUM>.

<FIG> depicts an embodiment of an adjustable finger splint <NUM>. The adjustable finger splint <NUM> may comprise a main body <NUM>, a slide <NUM>, a dorsal pad <NUM>, and a palmar pad <NUM>, as discussed above. As illustrated, the slide <NUM> and the palmar pad <NUM> are movable relative to the main body <NUM> and the dorsal pad <NUM>, such that as the slider is moved in a direction indicated by <NUM>, the finger of the user is increasingly straightened relative to the hand. In this manner, the user may control the amount of pressure applied based on the user's comfort level.

<FIG> depicts the main body <NUM>, the slide <NUM>, the dorsal pad <NUM>, and the palmar pad <NUM> separated from one another. As shown in <FIG>, the main body <NUM> can have a frame <NUM> including a slide platform <NUM>, a MCP platform <NUM>, and a PIP platform <NUM>. The slide <NUM> can comprise a wedge <NUM> and a slide rail <NUM>.

The slide platform <NUM> can be positioned at or near the bottom of the frame <NUM> and can extend along at least a portion of the main body. In some embodiments, the slide platform <NUM> can be coupled with the frame <NUM> via an adjustable hinge <NUM>, such that the angle of the slide platform <NUM> relative to the frame <NUM> can be adjusted. As will be discussed below, the slide rail <NUM> of the slide <NUM> can slide along the slide platform <NUM> during use.

The MCP platform <NUM> can extend out behind the frame <NUM> at a position above the height of the slide platform <NUM>, such that at least a portion of the slide rail <NUM> of the slide <NUM> can fit between the top of the slide platform <NUM> and bottom of the MCP platform <NUM>, as discussed above. In some examples, at least a portion the MCP platform <NUM>, such as an MCP extension <NUM> protruding downward from the MCP platform <NUM>, can contact the slide rail <NUM> of the slide <NUM> during use, thereby helping to keep the slide <NUM> in place within the main body <NUM>. As will be discussed below, a user's MCP joint can contact the top of the MCP platform <NUM> during use.

The PIP platform <NUM> can be positioned at the top of or supported by the frame <NUM>. The dorsal pad <NUM> can be coupled to the underside of the PIP platform <NUM>, as discussed above. The PIP platform <NUM> and dorsal pad <NUM> can be positioned above the height of the MCP platform <NUM>, such that a user's finger can be inserted into a space between the MCP platform <NUM> and the dorsal pad <NUM>. During use, the top of a user's PIP joint can contact the underside of the dorsal pad <NUM> when the user's finger is inserted into the adjustable finger splint <NUM>.

During use, the slide rail <NUM> of the slide <NUM> can be moved along the slide platform <NUM> of the main body <NUM>, such that the slide <NUM> is movable relative to the main body <NUM>. In some examples, the slide rail <NUM> and the slide platform <NUM> can be slideably coupled with each other, such as by having a protrusion in one of the slide rail <NUM> or the slide platform <NUM> notched into a groove that extends along the other one of the slide rail <NUM> or the slide platform <NUM>.

The wedge <NUM> can be coupled to the top of the slide rail <NUM>. However, in the current example, the wedge <NUM> may be releasably coupled to the slide rail <NUM>, such that wedges <NUM> having different curvatures may be used in conjunction of the splint <NUM> to treat an injured finger. The top of the wedge <NUM> can be shaped with a curvature, as discussed above. The slide <NUM> can be moved along the slide platform <NUM> to adjust the position of the wedge <NUM> relative to a finger inserted into the adjustable finger split <NUM>.

In this example, the palmar pad <NUM> rests on the wedge <NUM> or be coupled with the wedge <NUM>, such that the bottom of a user's DIP joint contacts the palmar pad <NUM> above the wedge <NUM> during use. The palmar pad <NUM> can slide along the curvature of the top of the wedge <NUM>, such that the palmar pad <NUM> can maintain contact with a user's DIP joint as the wedge <NUM> moves underneath the palmar pad <NUM>. In some examples, the palmar pad <NUM> can be separate from the wedge <NUM> and be held in place against the wedge <NUM> by the presence of the user's finger. In other examples, the palmar pad <NUM> can be slideably coupled with the wedge <NUM>, such as by having a protrusion in one of the palmar pad <NUM> or wedge <NUM> notched into a groove that extends along the other one of the palmar pad <NUM> or wedge <NUM>.

Although in some embodiments the elements of the PIP platform <NUM> can be fixed in position on the frame <NUM>, in other embodiments components of the PIP platform <NUM> can be moveable and/or openable to make it easier to insert a finger into the adjustable finger splint <NUM> or to remove a finger from the adjustable finger splint <NUM>.

Additionally, the main body <NUM>, the slide <NUM>, the dorsal pad <NUM>, and the palmar pad <NUM> are shown as releasable components of the adjustable finger splint <NUM>. However, it should be understood that one or more of the components <NUM>-<NUM> may be formed as a single component. For example, the palmar pad <NUM> may be secured to the slide <NUM> via a tongue and groove coupling, to allow the palmar pad <NUM> to move independently from the slide <NUM> along the length of the curvature of the wedge <NUM>. In another example, the slide <NUM> may be coupled over the slide platform <NUM> in a manner that the slide <NUM> may move independently along the length of the slide platform <NUM> during use but remain coupled when a finger is not engaged with the finger splint <NUM>.

As shown in <FIG>, in some of these moveable and/or openable embodiments, the PIP platform <NUM> can have a moveable panel <NUM>, one or more buckle elements <NUM>, and a latch <NUM>. The moveable panel <NUM> and the one or more buckle elements <NUM> can be hingeably coupled with the frame <NUM>. The latch <NUM> can be on at least one of the buckle elements <NUM> and be configured to selectively lock the buckle elements <NUM> over the moveable panel <NUM>. The dorsal pad <NUM> can be coupled with the underside of the moveable panel, as shown below.

When a finger is to be inserted into the adjustable finger splint <NUM>, the buckle elements <NUM> and moveable panel <NUM> can be angled upward, as shown in <FIG>. The PIP platform <NUM> can thus be opened relative to the MCP platform <NUM> and/or slide <NUM>, thereby providing more room for a finger to be inserted into the adjustable finger splint <NUM>, as shown in the side view of <FIG>. For example, an injured finger with extreme flexion that cannot easily be straightened to fit into the adjustable finger split <NUM> can be given more room by opening the PIP platform <NUM> and angling the moveable panel <NUM>.

To close the PIP platform <NUM>, the moveable panel <NUM> can be lowered as shown in <FIG>, and the buckle elements <NUM> can then be lowered over the moveable panel <NUM> as shown in <FIG>. The latch <NUM> than then be used to lock the buckle elements <NUM> over the moveable panel <NUM> as shown in <FIG>.

When the finger is to be removed, the latch <NUM> can be released, such as by releasing a tab on the latch <NUM>, thereby freeing the buckle elements <NUM> and moveable panel <NUM> to again be angled upward as shown in <FIG> such that there is more room to remove a finger from the adjustable finger splint <NUM>.

It should be understood that the examples illustrated in <FIG>, a buckle element <NUM> is shown to allow the bent finger of a user to be inserted into the adjustable finger splint <NUM>. However, it should be understood that other types of latches, locks, joints, and openings may be used to allow a bent finger sufficient access to the opening in the adjustable finger splint <NUM>.

<FIG> depicts the adjustable finger splint <NUM> in use. As shown in <FIG>, the wedge <NUM> of the slide <NUM> can be retracted at least partially into the frame <NUM> by sliding the slide rail <NUM> along the slide platform <NUM> of the main body <NUM>. A user's finger can then be placed into the adjustable finger splint <NUM> such that the bottom of the finger's MCP joint contacts the MCP platform <NUM>, the top of the finger's PIP joint contacts the dorsal pad <NUM> underneath the PIP platform <NUM>, and the bottom of the finger's DIP joint contacts the palmar pad <NUM> above the wedge <NUM>. As discussed above with respect to <FIG>, in some embodiments the PIP platform <NUM> can be opened and/or angled to assist with insertion of the finger, followed by closing and locking the PIP platform <NUM> after the finger is in place.

After a user's finger is in place within the adjustable finger splint <NUM> with the slide <NUM> retracted, as shown in FIG. 4A, the slide <NUM> can be distally extended by sliding the slide rail <NUM> along the slide platform <NUM>, as shown in FIG. As the slide <NUM> is distally extended, the curvature of the wedge <NUM> can press the finger's DIP joint upward by increasing amounts as the slide <NUM> slides farther along the slide platform <NUM>. The palmar pad <NUM> can also move along the top of the wedge <NUM> and change its incident angle as the slide <NUM> is distally extended, with the curvature of the wedge <NUM> causing the angle and position of the palmar pad <NUM> to match the angle and position of the finger's DIP joint as the wedge <NUM> moves underneath the palmar pad <NUM>.

In some examples, the main body <NUM> and/or slide <NUM> can have a locking mechanism, such as a latch, buckle, or ratchet, that can at least temporarily hold the slide <NUM> in place relative to the main body <NUM> once it has been distally extended and positioned for treatment of an inserted finger. In other examples, the force of an inserted finger pressed against the palmar pad <NUM> and wedge <NUM> and/or the contact of the slide rail <NUM> against the MCP extension <NUM> or other portion of the MCP platform <NUM> can help maintain the slide <NUM> in place during treatment.

As shown in <FIG>, the slide <NUM> can be extended from the main body <NUM> by squeezing the back of the slide rail <NUM> and the front of the slide platform <NUM>, thereby pushing the slide <NUM> along the slide platform <NUM>. Such a squeezing motion provide forces in opposing directions that are substantially parallel to the finger within the adjustable finger splint <NUM>. Such opposing parallel forces can have less impact on an injured finger than torque forces introduced by other devices that operate by turning screws to move components.

As noted above, in some examples the slide platform <NUM> can be moveable relative to the rest of the main body <NUM> via a hinge <NUM>, such that the angle of the slide platform <NUM> and the slide <NUM> can be adjusted. The angle of the slide <NUM> can therefore be adjusted in order to treat different injuries of different types and/or severities. For example, in <FIG>, the slide platform <NUM> is angled upward so that the slide <NUM> can be positioned to treat an interphalangeal joint from about <NUM>° flexion to about <NUM>° hyperextension. However, the slide platform <NUM> can also be positioned to be flat or angled downward to position the slide <NUM> for treatment of more severely contracted joints. In examples in which the PIP platform <NUM> can be angled and/or opened, as discussed above with respect to <FIG>, the PIP platform <NUM> can be unlatched to allow a finger to be inserted or removed without adjusting the angle of the slide platform <NUM> and slide <NUM>.

<FIG> depicts an example views of an adjustable finger splint <NUM> with adjustable proximal interphalangeal platform <NUM> according to some implementations. In some situations, the dorsal pad <NUM> may need to be customized to the individual being treated and/or the shape of the dorsal pad <NUM> may be adjusted during treatment to gradually allow the injured finger to achieve an extended or straightened position. For example, an injured individual may start treatment with a dorsal pad <NUM> with an arc similar to that of <FIG>, reach a mid-way point and continue treatment with dorsal pad <NUM> of <FIG>, and then complete the treatment with a dorsal pad of <FIG>. Thus, the dorsal pad <NUM> eventually is substantially horizontal and allows the finger to fully extend at a period of time nearing the completion of treatment.

In these examples, the PIP platform <NUM> is also configured to releasably couple or decouple from the frame <NUM>. In this example, the PIP platform <NUM> may include mating components <NUM> configured to mate with paired mating components <NUM> on the frame <NUM>. For instance, a user may pinch or apply inward pressure on the bottom of the PIP platform <NUM>, align the mating components <NUM> and <NUM>, and release to position the PIP platform <NUM> with the frame <NUM>. In some cases, the relative position of the PIP platform <NUM> with the frame <NUM> may be adjusted based on characteristics of the finger being treated. For example, the PIP platform may be tilted forward or backward relative to the frame <NUM>. As one illustrative example, the PIP platform <NUM> may be initially tilted forward and adjusted backward toward an upright configuration as treatment progresses.

<FIG> depicts an example side view of an adjustable finger splint <NUM> with adjustable proximal interphalangeal platform <NUM> according to some implementations. In the illustrate example, the frame <NUM> is again releasably coupled to the PIP platform <NUM>. However, in this example the PIP platform <NUM> may slide in a lock with the frame <NUM> using the mating components <NUM> and <NUM>.

<FIG> depicts an example perspective view of an adjustable finger splint <NUM> with ratchet locking system <NUM> according to some implementations. In this example, the slider <NUM> includes female ratchet components <NUM>(A) and the slider platform <NUM> of the main body <NUM> includes mating male ratchet components <NUM>(B). In this example, as the user move the slider <NUM> forward, the female ratchet components <NUM>(A) move over the male ratchet components <NUM>(B) due to the force applied by the user. When the user releases the slider <NUM> the female ratchet components <NUM>(A) aligned with the male ratchet components <NUM>(B) mate and lock together. When mated, the ratchet locking system <NUM> is able to provide additional friction to hold the slider <NUM> at the desired position relative to the main body <NUM> to better maintain desired pressure on the injured finger.

It should be understood, that while the current example includes a ratchet system <NUM>, other types of locking systems may be utilized, such as a screw based system, lever based system, or crank based system, and the exact position of the locking system may be move, for example place along the inner surface of the walls of the frame <NUM> rather than along the top surface of the slider platform <NUM>.

<FIG> depicts an example perspective view of an adjustable finger splint <NUM> with a two-part <NUM>(A) and <NUM>(B) palmar pad <NUM> and guided slide <NUM> according to some implementations. In the current example, the palmar pad <NUM> is divided into two parts, the front portion <NUM>(A) and rear portion <NUM>(B). The front portion <NUM>(A) is coupled to the slide <NUM> and the rear portion <NUM>(B) is coupled to the MCP platform <NUM>. In the current example, the slide <NUM> is also coupled to a guide along the inner walls (not shown) of the frame <NUM>. For instance, the slide <NUM> may include a groove <NUM> that mates with the guide on the frame <NUM>. The mated guide and groove <NUM> may allow the slide <NUM> to be maintained along a desired path with respect to the main body <NUM> during treatment.

<FIG> depicts an example back view of an adjustable finger splint <NUM> with a guided slide <NUM> according to some implementations. As illustrated, the slide <NUM> includes grooves <NUM> along the left-hand and right-hand walls that substantially mirror guides <NUM> along the inner walls of the frame <NUM>. As shown, a gap <NUM> may separate the slide <NUM> from the main body <NUM> and allow the slide <NUM> to move relative to the main body <NUM> while the grooves <NUM> and the guides <NUM> maintain a path of the slide <NUM> with respect to the main body <NUM>. In this example, a top groove <NUM> along a top surface of the slide <NUM> and a corresponding guide <NUM> along the main body <NUM> may also assist in maintaining the path of the slide <NUM> with that of the main body <NUM>. In some cases, the top groove <NUM> may also the slide <NUM> to move or slide within or be slideably coupled to the slide <NUM>.

In the current example, the palmar pad <NUM> is divided into two parts, the front portion <NUM>(A) and rear portion <NUM>(B). The front portion <NUM>(A) is coupled to the slide <NUM> and the rear portion <NUM>(B) is coupled to the MCP platform <NUM>. In the current example, the slide <NUM> is also coupled to a guide along the inner walls (not shown) of the frame <NUM>. For instance, the slide <NUM> may include a groove <NUM> that mates with the guide on the frame <NUM>. The mated guide and groove <NUM> may allow the slide <NUM> to be maintained along a desired path with respect to the main body <NUM> during treatment.

<FIG> depicts an example pictorial view of an adjustable finger splint in use according to some implementations. As discussed above with respect to <FIG> and <FIG>, the user may apply forward pressure on the back end <NUM> of the slide <NUM> to cause the slide <NUM> to engage an injured finger <NUM> with the front portion of the palmar pad <NUM>(A). In this example, the user <NUM> may apply pressure to the slide <NUM> via the thumb <NUM>. In this manner, the user <NUM> is able to control the amount of pain caused by the treatment and, in some situations, to remove the hand from the splint <NUM>, allowing the user <NUM> use of the hand and a break from the pain.

Claim 1:
An adjustable finger splint (<NUM>) comprising:
a main body (<NUM>) including:
a metacarpophalangeal (MCP) platform (<NUM>) having at least one front surface to allow a user to apply a first pressure to the adjustable finger splint;
and
a frame (<NUM>) coupled to the MCP platform (<NUM>), the frame (<NUM>) extending upward from the MCP platform (<NUM>) and defining a cavity (<NUM>), the cavity (<NUM>) to receive a finger; and
a slide (<NUM>) to releasably couple to the main body (<NUM>) within the cavity (<NUM>) to allow the slide (<NUM>) to move relative to the main body (<NUM>), the slide (<NUM>) having a wedge (<NUM>), the wedge having a predefined curvature and the slide (<NUM>) having a back surface to allow the user to apply a second pressure to the adjustable finger splint (<NUM>), the second pressure in a direction substantially opposite the first pressure;
said predefined curvature configured to cause the finger when located in said cavity to straighten as the slide (<NUM>) is pushed towards the front end (<NUM>) of the finger splint (<NUM>) by said first and second pressures, the front end (<NUM>) positioned away from the user during use.
