Description
FIELD OF THE INVENTION

The invention relates generally to the field of orthopedic or prosthetic devices and more specifically to cervical collars having height and circumferential adjustment with a mandible support.


BACKGROUND

Cervical collars are used in the treatment, stabilization, immobilization, and therapy of cervical trauma. Some collars are intended to provide support for whiplash and other such injuries where support for the head and neck is needed. Other collars are intended for near complete immobilization of the head and neck, such as in an EMS pre-hospital setting.


There is often a rush to apply these collars onto the wearer due to the acute nature of cervical injuries. The collar must be selected to accommodate the wearer's size in a quick manner for effective stabilization and immobilization of the neck of the wearer.


Known cervical collars restrict spine flexion, extension and rotation to promote wearer recovery. Such known collars also include a trachea opening allowing for healthcare clinicians the ability to perform quick carotid pulse monitoring and emergency tracheotomies while providing cervical immobilization.


A drawback to known collars is that they are individually sized for a variety of standard wearer sizes. There is a need to store many different sized collars in inventory which significantly adds to the cost for using such collars. If there is an emergency, and the proper sized collar is not available, the caregiver is given little option other than to apply a poorly fitting collar on the wearer since many known collars provide minimal size adjustment.


Proper sizing is critical for wearer immobilization and comfort. While there are a variety of different standard sizes, the wearer may have dimensions which fall outside of the standard sizes, and wear a poorly fitting collar that insufficiently immobilizes the wearer's neck. Such poor fitting may also cause significant discomfort to the wearer.


Over time, swelling of the wearer's neck may reduce which further complicates the sizing of the collar. This may lead to the need for disposing the initially selected collar and replacing it with a new collar. This may lead to waste and an increase in cost.


When sizing a cervical collar, the first notable dimension concerns the height. The height is measured by the vertical distance from the tip of the chin to the sternum; the other key dimension concerns the circumference of the wearer's neck.


Besides sizing, proper application of the collar is necessary for immobilization and wearer comfort. A typical collar includes of front and rear components packaged as a set according to the size of the wearer.


When applying a collar to the wearer, the rear component of the collar applies to the back of the wearer's neck. Once the back wearer is positioned appropriately, the front component of the collar is positioned against the front or anterior portion of the neck so a chin support is placed against the chin. The front component is centered to secure neutral alignment. The front component overlaps the rear component to ensure effective immobilization and comfort. Straps are then tightened to the collar with a bilateral adjustment which secures the wearer's cervical region in neutral alignment.


An issue with known collars is that the collars typically only provide support under the mid-front of the chin, and lack support under the mandible (lower jaw or jaw bone). From this, there is often undue pressure exerted on the chin of the wearer, which may cause discomfort and sores.


Another issue with known collars having frontal or anterior sternum footplates is that the footplate has a tendency to be positioned closer to the neck than the chin part of the collar, the footplate is too flexible, and the collar can be easily yet detrimentally fitted too tight resulting in the sternum pad to sit on a clavicle.


Yet another issue with known collars is that such collar with an adjustable sternum footplate is that existing locking system were insufficiently strong to prevent buttons or locks from unlocking.


SUMMARY

The present disclosure describes a cervical collar having height and circumferential adjustment to accommodate a wide variety of sizes of different patients and to accommodate size changes caused by increased or decreased swelling of the affected anatomical portions of the patients.


Features of the cervical collar include a removable height support piece to allow the collar to be adjusted or removed for cleaning or to check for pressure sores, without removing life support attachments such as breathing and feeding tubes. The support piece includes a footplate without a hinge at its extension to provide a more rigid footplate when applied against a wearer's sternum so a chin insert for supporting the mandible is generally aligned or closely aligned with one another.


A locking system is provided for locking the support piece in that the locking system includes spring locks for securely retaining the support piece to the anterior component. The support piece is stiffened to assure that the support piece provides stable and secure support.


Flexible or compliant edges and anatomically shaped portions on the cervical collar are provided to accommodate different sized users, to accommodate changes in anatomical shape due to an increase or decrease in swelling, and to prevent pressure peaks, even if the collar is improperly applied to the patient.


The disclosed cervical collar is configured to conform to the anatomy of the patient, and to further to be a generally constant contact collar that contacts the skin of the patient such that when the collar allows some amount of patient movement, the collar moves with the patient.


The combination of flexible or compliant edges and anatomically shaped portions on the cervical collar with ventilation mechanisms, such as ventilation slots, allow the collar to have intimate contact with the skin of the patient (with or without a liner). The posterior component is provided with a plurality of living hinges formed by constructing a flexible posterior of the posterior component in combination with a main support piece, particularly along a plurality of slots formed alongside portions of the posterior component. The flexible material forming the flexible edge extends from the periphery of the posterior component to the slots, at least on one side of the posterior component, which are provided for allowing a strap to secure to the posterior component.


The cervical collar has a mandible support that distributes pressure more evenly about the chin and mandible to prevent excessive pressure. The collar's attachment system of anterior and posterior components is adjustable to provide a more flexible strap system under the mandible portion of the collar.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

A. Environment and Context


Embodiments of an orthopedic device are provided for stabilizing and supporting anatomical portions of a patient, for example, the neck and head of a patient.


Although the embodiments of the disclosure are adapted for supporting and stabilizing anatomical portions of many patients having various anatomical shapes and sizes, the embodiments of the disclosure may also be dimensioned to accommodate different types, shapes and sizes of anatomical portions.


Exemplary materials and configurations for components of the orthopedic device, such as the structural supports or shells and flexible or compliant portions, and exemplary uses and connection mechanisms are described in U.S. Pat. No. 5,180,361 , granted January 1993, U.S. Pat. No. 5,445,602, granted August 1995 , U.S. Pat. No. 5,622,529, granted April 1997, U.S. Pat. No. 5,632,722, granted May 1997, U.S. Pat. No. 5,716,335, granted February 1998, U.S. Pat. No. 6,071,255, granted June 2000, U.S. Pat. No. 6,254,560, granted July 2001, U.S. Pat. No. 6,663,581, granted December 2003, U.S. Pat. No. 7,018,351, granted March 2006, U.S. Pat. No. 7,198,610, granted April 2007, and U.S. Pat. No. 7,981,068, granted Jul. 19, 2011, and U.S. patent application publication 2011/0066094, published Mar. 17, 2011,and all incorporated in the entirety by reference.


For ease of understanding the disclosed embodiments of an orthopedic device, the anterior and posterior portions of the orthopedic device are described independently. The anterior and posterior portions of the orthopedic device function together to form a supporting and stabilizing collar that encompasses the anatomical portions of the wearer.


For further ease of understanding the embodiments of an orthopedic device as disclosed, a description of a few terms is necessary. As used, the term “proximal” has its ordinary meaning and refers to a location situated next to or near the point of attachment or origin or a central point, or located toward the center of the body. Likewise, the term “distal” has its ordinary meaning and refers to a location situated away from the point of attachment or origin or a central point, or located away from the center of the body. The term “posterior” also has its ordinary meaning and refers to a location behind or to the rear of another location. The term “anterior” has its ordinary meaning and refers to a location ahead of or to the front of another location.


The terms “rigid,” “flexible,” “compliant,” and “resilient” may be used to distinguish characteristics of portions of certain features of the orthopedic device. The term “rigid” should denote that an element of the device is generally devoid of flexibility. Within the context of support members or shells that are “rigid,” it is intended to indicate that they do not lose their overall shape when force is applied, and in fact they may break if bent with sufficient force. The term “flexible” should denote that features are capable of repeated bending such that the features may be bent into retained shapes or the features do not retain a general shape, but continuously deform when force is applied.


The term “compliant” may qualify such flexible features as generally conforming to the shape of another object when placed in contact therewith, via any suitable natural or applied forces, such as gravitational forces, or forces applied by external strap mechanisms. The term “resilient” is used to qualify such flexible features as generally returning to an initial general shape without permanent deformation. As for the term “semi-rigid,” this term is used to connote properties of support members or shells that provide support and are free-standing; however such support members or shells may have some degree of flexibility or resiliency.


B. Embodiments of the Cervical Collar


Under the embodiments described, the cervical collar 10 includes an anterior component 12 and a posterior component 14, which are similar in part to those described in U.S. Pat. No. 7,981,068. The cervical collar 10 also includes a height support 16 adjustably securing to the anterior component 12 and combining therewith to form a tracheal open access area 48. A two part liner 28, 29 can be provided as an interface between the patient and the respective anterior and posterior components 12, 14. A removable chin support 18 is secured to an interior or inside portion of the anterior support 12. A strapping system 26 is provided to secure the anterior and posterior components 12, 14 to one another.


Both the anterior and posterior components 12, 14 may be formed at least from a rigid or semi-rigid main support portion 34 and a resilient or flexible portion 36 surrounding sections of the main support portion 34. A fuller explanation of these components and variations are found in U.S. Pat. No. 7,981,068.


The adjustable height support 16 includes two upright legs 22 configured to cooperate with depending projections 24 formed by the anterior component 12. Recessed portions are formed in the upright legs 22 and have a corresponding shape to the depending projections 24 for receiving the respective depending projections 16 to allow the adjustable height support 16 to be positioned at different heights along the depending projections 24. A more detailed description of the height support is found in U.S. patent application publication 2011/0066094.


As shown in FIGS. 1B and 1C, each upright leg 22 includes a locking button 23 that can be manipulated to selectively lock the adjustable height support 16 from being adjusted to a shorter height. The buttons 23 are received in appropriately sized and shaped cut out portions of the upright legs 22


Each button 23 includes a pivot axle 45 (not shown but resembling an axle in U.S. patent application publication 2011/0066094), received in the upright leg 22, to allow the button 23 to pivot thereon from an engaged, locked position, to a disengaged, unlocked position. The button 23 may include at least one locking protrusion configured to selectively engage a corresponding portion of the cut out portions of the upright legs 22 to selectively lock the button 23 in the engaged, locked position to prevent accidental movement of the height support 16 to a shorter height.


A tooth or teeth 47 (shown with a tooth) may be formed along a reduced thickness portion of the pivot axle 45 for selective engagement with the locking projections or ratchets 51 formed on the depending projections 24, as shown in FIG. 1D. The locking projections 51 are preferably flat surfaces and each have a height spaced apart by slots 49 along the height of the depending projections 24. The teeth 47 may be formed similarly, but in opposition to, the locking projections 51, such that the teeth include a first edge having a first thickness that tapers out to a linear edged having a second thickness that is larger than the first thickness, wherein the linear edges of the teeth engage with the linear edges of the locking projections or ratchets o selectively lock the height support from being adjusted to a shorter height.


A protrusion 59 may extend from the lever 33 and engage an opening formed along the upright leg 22, or alternatively abut against a side of the upright leg.


When the buttons 23 are pivoted to the disengaged, unlocked position, the teeth are removed from contacting the locking projections 51 formed on the depending projections 24. The height support 16 can freely move either up or down to either decrease or increase the height. In this manner, the position of the height support 16 on the associated depending projections 24 can be altered to accommodate different anatomical sizes of wearers.


When the buttons 23 are pivoted to the engaged, locked position, the teeth are in contact with the locking projections or ratchets formed on the depending projections, and the engagement of the linear edges of the teeth and the locking projections or ratchets prevents the movement of the height support 16 in the upward direction to prevent the height support 16 from being adjusted to a shorter height. However, since the teeth are formed on a reduced thickness portion of the pivot axle, the height support can be moved downward to be adjusted to an increased height, since the reduced thickness portion of the pivot axle provides resiliency to the teeth and allows the tapered portions of the teeth to slide over the tapered portions of the locking projections or ratchets.


In this manner, the position of the height support 16 on the associated depending projections can be adjusted to increase the height without manipulating the buttons 23. This feature is a benefit for quickly applying the cervical collar to a patient. The cervical collar can be packaged with the height support 16 positioned in the shortest height configuration, to save on packaging space, and the buttons 23 positioned in the engaged, locked position.


Fine tuning of the height of the cervical collar can be achieved by unlocking and pivoting the buttons 23 to the disengaged, unlocked position, and adjusting the height of the height support 16 as needed.


Height adjustment indicia may be provided on the depending projections to provide easy sizing of the cervical collar using predetermined sizes, such as small, medium, large, etc. The height adjustment indicia can be in standardized, color coded markings and/or lines that reflect standardized marking systems used to indicate patient sizes. Other indicia, such as alphanumeric labels, can also be used. The height adjustment indicia cooperate with leading edges of the adjustable height support to provide an indication of the current sizing of the cervical collar.


According to the embodiment of FIG. 1, the buttons 23 include a resilient tab 38 that engages a side portion 76 of the upright leg 22 to secure placement of the leg 22 relative to the depending projections 24. A lever 33 is formed on an opposite side to the resilient tab 38 to facilitate closing of the button 23. The tab 38 may be resiliently biased to extend over the side portion 76, whereas adjacent arms 39 to the tab 38 do not extend over the side portion 76, and may fit within the cut out portion defined by the legs 22 that permit rotation of the buttons about the axle. The tab 38 may be disengaged by being pressed into the cut out portion to rotate the button and disengage from the depending projections 24.


The tab has the advantage in that it prevents the size of the collar, particularly the height support, from being adjusted accidentally; it securely retains the collar. The tab requires the button to be pushed down prior to unlocking the button, firmly retaining the button against accidental adjustment, as shown with FIGS. 8A-8D. A retainer 35 is formed on the anterior component adjacent to the height support 16 to guide sliding motion of the height support 16 relative to the anterior component.


A non-hinged distal sternal part 20 is connected at connection 44 to the distal end of the adjustable height support 16, and includes a footpad 40 thereon. Unlike in prior art cervical collars, the connection 44 is preferably provided without a hinge to reduce pressure points on the sternum which occurs when a hinge is provided as the connection. The thickness at the connection 44 is continuous without variations; a living hinge would be considered to have a variable thickness to facilitate a bending by forming a weakened section.


By removing a hinge at the connection 44, the chin support 18 and the sternum part 20 are more in line with each other to avoid the footpad 40 from being placed too close to the neck than the chin support itself which should overlie the sternum plate to better distribute pressure by the footpad 40. The removal of the hinge at the connection makes the connection more rigid, and prevents the collar from being fitted too tight and the footpad being placed on the clavicle rather than the sternum.


The footpad 40 can be an integrally formed footpad, or a removable and/or replaceable footpad configured to engage an anatomical portion, such as the sternum. To provide comfort to the wearer and to avoid skin ulceration, the footpad 40 can be a resilient or compliant pad formed by overmolding. The footpad 40 can also be formed as open or closed cell foam padding, and/or a disposable hydrophilic foam pad.


As best seen in FIGS. 1-3, the posterior component 14 has side extensions 41 that include a plurality of spaced substantially vertically oriented or angled arcuate slots 30 that aid with ventilation of the orthopedic device in use, and provide affixation regions 46 by which the straps 26 of the strapping system may be looped with loop 54, secured, threaded and applied to the receiving section 50 on the anterior component.


To provide additional resiliency or living hinges, flexible material regions 42 are provided at opposed ends of the slots 30 to allow the posterior component 14 to bend circumferentially at the side extensions 41 to conform to the anatomical portion of the user, such as the neck. Side portions 43 bordering the slots are preferably formed from a more rigid material to withstand forces exerted by the strap 26 which may be selectively looped 54 at one end to at least one of the side portions 43. The flexible material regions 42 may cover thinned regions of the rigid material or the side portions 43 may be embedded within the flexible material forming at least part of the flexible material regions 42.


The strapping system has an advantage of preventing unexpected opening of the collar or separation of the anterior component from the posterior component. The slots provide vents and selective points for threading and securing the strap. The flexible material regions also allow the posterior component to better conform to the anatomy of the wearer which prevents the collar from opening up since the rigid material in combination of with the flexible material now has breaks rather than urging the collar into an open configuration.


According to the embodiment of FIG. 1, the chin support 18 is centrally fixed at a center portion 53 secured to the anterior component 12 at a supporting spring portion 60 by a locking pin 56 extending from the chin support 18. The spring portion 60 provides a stable but dampening support under the chin of the patient, and restricts flexion. Using the supporting spring portion 60 in combination with a flexible edge of the flexible portion also aids with reducing or eliminating pressure points.


Side or mandible portions 55 of the chin support 18 slidably engage slots 52 formed from the rigid or semi-rigid main support portion 34 and are located alongside corresponding side extensions 68 of the anterior support 12. The side portions 55 may also pivot generally upwardly and downwardly relative to the side extensions due to the connection therewith. The side portions 55 have a retention element 32 retained by the slots 52 which permit the side portions 55 to move relative to the anterior support 12 to conform to movement and anatomy of a wearer's chin.


In referring to the embodiment of FIG. 4, while the center portion 53 is secured against the spring portion 60 (depicted as spaced away since the locking pin 56 has not yet been pressed to engage the spring portion), the chin support 18 includes spacers 58 on the side portions 55 at which the retention elements 32 extend. The side portions 55 are used to space the chin support 18 away from the side extensions 68 to provide better support under the wearer's mandibles.


The chin support 18 may include appropriate hook and loop elements 62, and may define a plurality of ventilation features 70. The liner 28 may extend over the chin support 18 continuously with the rest or portions of the anterior component 12.


In observing FIGS. 4-6, each of the chin supports 18, 64 depicted have a different contour at the center portion 53, 70 which may be adapted for different anatomies of wearers. In the chin support 18 of FIG. 4, the center portion is generally continuously formed with the side portions 55 to provide a greater surface area for the chin and mandibles. In the variation of FIGS. 5 and 6, the chin support 64 has a narrowed center portion 70 which has a shape generally corresponding to the spring portion 60, and extends more outwardly inwardly toward the wearer's mandible at side portions 66. There are no spacers to this variation unlike in the variation of the chin support 18 of FIGS. 1-4.


The chin support 64 of FIGS. 5 and 6 may retrofit existing cervical collars, as shown by the example of FIG. 7. The chin support 64 has a central locking pin 56 at the center portion and side pins 72 which may be inserted and locking to corresponding apertures that can be formed through existing collars. The chin support 64 may be provided with appropriate spacer protrusions 74 formed along its periphery as considered necessary to better place the chin support 64 against the wearer.


The chin support eliminates pressure points on the chin and mandible of the wearer by providing a larger surface and extended support, such as by the spacers, which enable the chin support to closely conform to the chin and the mandible. The sliding mechanism or connection of the chin support to the anterior component enables the chin support to closely conform to various anatomies and to accommodate swelling as the wearer undergoes treatment and heals.


In observing FIGS. 8A-8D and the foregoing drawings, various steps may be employed for sizing the collar. First, FIG. 8A shows that the locking buttons are unlocked by squeezing them together. If the locking buttons are already locked, the tab is pressed and released, as shown in FIG. 8B. FIG. 8C shows that once the wearer's phenotype is determined, preferably from a sizing chart, the height support is adjusted to the appropriate height setting according to the indicia on the legs. In FIG. 1, a cut-away 37 is used to identify one of several different sizes that may be listed on the depending projections 24. Once the sizing is set, the locking buttons are locked by being rotated outward or away from the midline of the collar. Tamper resistance is obtained by ensuring the locking buttons are rotated outward until an audible click is heard by the tab placed into engagement with the side portion of the leg.



FIGS. 9A-9F exemplify application of the collar. According to FIG. 9A, the wearer is positioned with arms to the side, shoulder down and head centrally aligned. The posterior component is slid behind the wearer's neck and is centered thereagainst. In FIG. 9B, the anterior component (having already been presized) is placed up under the chin in which the front edge of the chin support is lined up with the front of the wearer's chin. The sides of the collar front should be oriented up, off the trapezius and toward the ears.


In reference to FIG. 9C, while holding the anterior component securely, the ends of the collar, including the footpad, are curled snugly against the wearer's neck. The strap system is used to secure the anterior component to the posterior component in which the straps are attached to the anterior component from the posterior component one at a time, to an equal length on both sides. According to FIG. 9E, the straps are trimmed once the collar is secured on the wearer, and FIG. 9F shows the collar is marked to indicate where the straps should be located once the collar is removed.



FIG. 9D depicts the instance where wearers of the collar remain in a supine position for an extended period of time consider removing a sternal pad belonging to the footplate for greater comfort. In this embodiment there are two pads attached to the footplate including a sternal pad and a primary pad adjacent the footplate structure itself, preferably made from SORBATEX which allows body moisture to pass through, dries quickly, inhibits microbial growth, and has good thermal conductivity. The primary pad should remain on the footplate.


Turning to FIGS. 10A-10C, the collar may be removed from the wearer as follows. The wearer should be placed in a supine position with the bed flat, and with the arms to the side, shoulders down and the head centrally aligned. FIG. 10A shows that one of the straps is removed and the collar is hinged open. The wearer can be observed for healing, rashes or debris, or the collar can be completely removed. FIG. 10B shows how the straps may be removed, with the anterior and posterior components separated from one another.



FIG. 11 shows the collar being adjusted for a tracheotomy tube. The collar can be removed without detaching a tracheotomy tube therefrom by loosening the straps and unlocking the locking buttons. The height support inclusive of the portions include the footplate can be slide from the collar down and from the front of the anterior support.
