This application is a non-provisional of U.S. Provisional No. 61/284,128 filed on Dec. 14, 2009 and entitled “FLUID STOCKING DONNER”.
The present disclosure relates generally to applying and removing compression garments from a body.
Compression garments are pieces of clothing, such as socks, pantyhose, sleeves, and/or the like, made from an elastic material. Compression garments provide support to the underlying tissue. Such support is especially useful for people who have to stand for long periods, or people with poor circulation, as a post surgical procedure to prevent clotting, and for athletes. The garments can come in varying degrees of compression. The higher degrees of compression typically require a doctor's prescription. Compression garments worn on the legs can help prevent deep vein thrombosis and reduce swelling, especially while traveling.
However, applying or removing compression garments is difficult at best and can be impossible for elderly or physically challenged persons. The task is often very difficult even with the assistance of a caregiver such as a family member, nurse or nursing assistant. Improved mechanisms and techniques for applying and/or removing compression garments and/or other similar garments thus remain desirable.
This disclosure relates to garment donning and doffing. In an exemplary embodiment, an apparatus for donning and doffing a compression garment comprises a sleeve configured with a first sleeve opening, a second sleeve opening, an inner surface and an outer surface. The first sleeve opening, the inner surface and the second sleeve opening cooperate to define a passage through the sleeve for a limb. The inner surface and the outer surface are formed of and defined by a continuous flexible material. The outer surface at the second sleeve opening is configured for contact with at least one opening of the compression garment such that the compression garment can be continuously everted throughout the sleeve until the end of the compression garment opposite the at least one opening abuts the first sleeve opening.
In another exemplary embodiment, a method for coupling a sleeve and a compression garment comprises placing a compression garment over a pole, everting a sleeve in a first direction along the pole such that the compression garment is located between the sleeve and the pole, tucking an end of the compression garment into the sleeve, and everting the sleeve along the pole in a second direction opposite the first direction to cause the compression garment to wrap around the sleeve.
In another exemplary embodiment, a method for donning a compression garment comprises providing a sleeve having a first sleeve opening, a second sleeve opening, an inner surface and an outer surface wherein the first sleeve opening, the inner surface and the second sleeve opening cooperate to define a passage through the sleeve for a limb. The inner surface and the outer surface being formed of a continuous flexible material. The method further comprises providing a compression garment having at least one opening at one end thereof, providing a pole extending from a surface, sliding the at least one opening over the pole until the compression garment is fully extended over the pole, placing the second sleeve opening on the pole opposite the surface, and sliding the sleeve over the pole whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the second opening while the outer surface becomes the inner surface at the first opening. The method further comprises pulling the at least one opening into contact with the outer surface at the second sleeve opening once the sleeve reaches the at least one opening, lifting the sleeve away from the surface whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the first opening while the outer surface becomes the inner surface at the second opening. The lifting continues until the compression garment is completely removed from the pole, the end of the compression garment opposite the at least one opening abutting the first opening. The method further comprises positioning the first sleeve opening over a patient's limb, rolling the sleeve up the patient's limb whereby the inner surface and the outer surface evert thereby leaving the compression garment on the limb, disengaging the at least one opening from the second sleeve opening, and rolling the sleeve back down the limb until removed from the limb.
In another exemplary embodiment, a method of doffing a compression garment from a limb comprises providing a sleeve having a first sleeve opening, a second sleeve opening, an inner surface and an outer surface wherein the first sleeve opening, the inner surface and the second sleeve opening cooperate to define a passage through the sleeve for a limb, the inner surface and the outer surface being formed of and defined by a continuous flexible material. The method further comprises placing the first sleeve opening on the limb, sliding the sleeve over the limb whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the first opening while the outer surface becomes the inner surface at the second opening, pulling at least one opening of a the compression garment into contact with the outer surface at the first sleeve opening once the sleeve reaches the at least one opening, and lifting the sleeve away from the surface whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the second sleeve opening while the outer surface becomes the inner surface at the first sleeve opening, the lifting continuing until the compression garment is completely removed from the limb, the end of the compression garment opposite the at least one opening abutting the second sleeve opening.
The contents of this summary section are provided only as a simplified introduction to the disclosure, and are not intended to be used to limit the scope of the appended claims.
With reference to the following description, appended claims, and accompanying drawings:
The following description is of various exemplary embodiments only, and is not intended to limit the scope, applicability or configuration of the present disclosure in any way. Rather, the following description is intended to provide a convenient illustration for implementing various embodiments including the best mode. As will become apparent, various changes may be made in the function and arrangement of the elements described in these embodiments without departing from the scope of the present disclosure.
For the sake of brevity, conventional techniques for garment donning, doffing, manufacture, use, and/or the like may not be described in detail herein. Furthermore, the connecting lines shown in various figures contained herein are intended to represent exemplary functional relationships and/or physical and/or communicative couplings between various elements. It should be noted that many alternative or additional functional relationships, physical connections, and/or communicative relationships may be present in a practical garment donning and/or doffing system or device.
Compression garments are often difficult to don and doff, particularly for physically challenged patients. Additionally, due to the compressive forces exerted by the garment, the garments may disrupt bandages or other clothing or medical equipment underneath the compression garment during donning and/or doffing. Due to these and other difficulties, various therapeutic benefits of compression garments often remain unrealized, as patients and/or caregivers struggle with the difficulties of using these garments as intended. Often, a patient may forego wearing a compression garment entirely due to the difficulty of having the compression garment properly put in place and/or removed.
In accordance with principles of the present disclosure, a garment donning system may be any system configured to facilitate donning and/or doffing of garments, for example compression garments. With reference now to

In various exemplary embodiments, with reference now to
In various exemplary embodiments, the inner surface 16 and the outer surface 18 are formed of and defined by a continuous flexible material 22. Material 22 may comprise silicone, thermoplastic elastomers (e.g., styrenic block copolymers, polyolefin blends, elastomeric alloys, thermoplastic polyurethanes, thermoplastic copolyester, thermoplastic polyamides, and/or the like), rubber, or any other suitable flexible material or combination of materials. Flexible material 22 may also be a gel substance, of a specific shore and/or combination of shores, that comprises the entire sleeve 10 throughout. The continuous flexible material 22 is flexible enough to convey sleeve 10 over a limb.
In various exemplary embodiments, sleeve 10 further comprises a fluid 70 contained within continuous flexible material 22. Fluid 70 generally facilitates two purposes, one of hydraulics and one of lubrication. Fluid 70 may be water, solutions of water, oil, air, foams, urethane, silicone, lubricants, soaps, and/or any other material which may have desired properties. In addition to fluid 70, sleeve 10 may further be filled with beads, for example generally spherical glass beads or plastic beads, in suspension to aid in the reduction of friction between the inner surface 16 and the outer surface 18. In certain exemplary embodiments, sleeve 10 is configured with a fill and drain port 102 which allows refining of the size of passage 20 and for efficiency when traveling. In an exemplary embodiment, with momentary reference to
In various exemplary embodiments, sleeve 10 may be filled with substances other than fluids, for example with beads, powders, petroleum jelly, and/or the like, or combinations of the same. In one exemplary embodiment, sleeve 10 is filled with powder. In another exemplary embodiment, sleeve 10 is filled with petroleum jelly. In another exemplary embodiment, sleeve 10 is filled with powder and petroleum jelly. The material or materials filling sleeve 10 and/or ratios may be selected according to the desired compression, the size of a patient's limb, and/or other suitable factors. By limiting the amount of fluid in sleeve 10, sleeve 10 may be configured to comply with requirements for commercial air travel, for example security requirements related to carry-on fluid volumes.
In an exemplary embodiment, a plurality of longitudinally continuous and parallel raised lines 24 extend outwardly from inner surface 16 and outer surface 18. In some exemplary embodiments, lines 24 extend generally parallel to a central axis of the generally toroidal or other shape of sleeve 10 (for example, as illustrated in
In various exemplary embodiments, lines 24 are spaced between about 2 mm and about 24 mm away from one another. In various exemplary embodiments, lines 24 are raised between about 0.5 mm and about 5 mm above inner surface 16 and outer surface 18. Moreover, lines 24 may be spaced, raised, and/or otherwise configured in any suitable manner.
In an exemplary embodiment, continuing to reference
In an exemplary embodiment, sleeve 10 may be constructed with a longitudinal seam 100 by removing sleeve 10 from an original mold, and then sealing sleeve 10 end to end, for example via heat and/or adhesive. In an exemplary embodiment, a frame and/or clamp may be utilized to facilitate sealing of sleeve 10. Additionally, fluid 70 may be utilized as a parting agent and/or a stiffener when sealing sleeve 10. For example, sleeve 10 may be partially filled with fluid 70, and the ends of sleeve 10 may then be joined and clamped. Moreover, sleeve 10 may be formed, filled, and/or otherwise constructed in any suitable manner and/or by any suitable mechanism.

Pole 26 may be coupled to a base mount 28. In an exemplary embodiment, base mount 28 is configured with a suction lever 30. When base mount 28 is placed on a flat smooth surface, a user 32 may operate suction lever 30 in order to hold pole 26 in place. Moreover, any suitable components and/or methods for removably and/or permanently fixing pole 26 in place may be utilized. Additionally, pole 26 may be mounted to and/or formed from a location where pole 26 may be regularly utilized, for example at a nurse's station in a hospital, on a hospital bed frame, and/or the like.

Compression stocking 50 may be “rolled around” sleeve 10 in order to form a suitable compression garment/sleeve assembly ready for installation on a limb. In an exemplary embodiment, with reference now to
In an exemplary embodiment, second opening 14 of sleeve 10 is placed on pole 26 opposite base unit 28 (for example, as illustrated in

In an exemplary embodiment, with continued reference to
In various exemplary embodiments, sleeve 10 and compression stocking 50 may be configured separately. In other exemplary embodiments, sleeve 10 and compression stocking 50 may be pre-configured together as a rolled-up sleeve/stocking assembly, for example as described above, and then offered as a unit to consumers, medical professionals, and/or the like.
In various exemplary embodiments, a rolled-up sleeve/stocking assembly may be utilized to apply a compression garment to a limb and/or remove a compression garment from a limb. Stated generally, sleeve 10 may be considered to facilitate “rolling” a compression garment onto a limb (i.e. “donning”), and/or “unrolling” a compression garment off a limb (i.e., “doffing”). With reference now to
In various exemplary embodiments, doffing of compression stocking 50 may be achieved via substantially a reversal of a donning process. In an exemplary embodiment, when compression stocking 50 is in place on a limb, compression stocking 50 may be removed from the limb, as follows: Sleeve 10 is rolled up limb 60 (for example, as illustrated in
In various exemplary embodiments, if sleeve 10 and compression stocking 50 are desired to be separated, pole 26 may be utilized. Moreover, it may be simpler to simply grasp toe 56 and then release sleeve 10. The weight of sleeve 10 can thus act to unroll compression stocking 50 from around sleeve 10.
In addition to use in donning and/or doffing garments, for example compression garments, sleeve 10 may be desirably utilized in connection with various medical procedures and/or therapies. For example, in various exemplary embodiments, sleeve 10 may be utilized in connection with edema management and/or decongestive therapy. Typically, physical therapists often treat patients with edema or swelling by massaging fluid back into tissue with their hands. In contrast, in an exemplary embodiment a physical therapist or other caregiver may utilize sleeve 10 for treatment of edema, for example by placing sleeve 10 over the hand of a patient, and then squeezing sleeve 10 as sleeve 10 is rolled slowly up the patient's arm. Because individual therapists have varying hand sizes and strength, utilization of sleeve 10 brings a first advantage of a standardized force to this discipline. It also allows for second advantage of a static variation, in that the therapist can release the force applied by them, and replace it with another sleeve 10 that causes the first sleeve 10 to lock in position and/or stay in place. The various sleeves 10 may be of varying shores and/or fluidity in order to provide a third advantage of a gradient pressure aspect on the limb.
Similarly, in various exemplary embodiments sleeve 10 may also be utilized for decongestive therapy. A common technique for decongestive therapy, for example to treat edema of a hand or arm, involves the caregiver holding the affected hand with one hand, and then using the caregiver's other hand to grasp the patient's wrist. The caregiver then repeatedly “milks” the edema away by slowly sliding this loose grip up the patient's arm. In contrast, in an exemplary embodiment a caregiver may utilize one or more sleeves 10, for example, two sleeves 10, to facilitate “milking” the edema away and allowing the caregiver's grip to slide up the arm of the patient.
In certain exemplary embodiments, sleeve 10 may be utilized in connection with therapeutic massage, relaxation massage, and/or the like. When utilized in connection with massage, sleeve 10 may be utilized to provide compressive forces to skin, muscle, connective tissue, lymphatic vessels, and/or any other suitable body parts in order to enhance function, stimulate blood flow, and/or promote relaxation. When sleeve 10 is utilized in connection with massage, sleeve 10 may be heated and/or cooled in order to enhance a desired result. Moreover, when sleeve 10 is utilized in connection with massage, sleeve 10 may be configured with various structures, external coatings, textures, and/or geometric features, for example in order to provide a desired pressure, tactile stimulation, or other physiological manipulation or stimulation to a massage patient.
In various exemplary embodiments, sleeve 10 may be at least partially filled with a material suitable for use as a heat pack and/or a cold pack. In this manner, sleeve 10 may be utilized to provide heat therapy and/or cold therapy to an affected area, for example in order to treat bruising, swelling, and/or the like. Moreover, skirt 103 may be utilized to retain sleeve 10 in a desired location, for example in order to facilitate transfer of therapeutic heat and/or cold to a target area.
In various exemplary embodiments, sleeve 10 is configured with a smooth surface lacking any lines 24. In these embodiments, sleeve 10 may comprise certain portions having a first coefficient of friction, and other portions having a second coefficient of friction different from the first coefficient of friction. Moreover, in various exemplary embodiments, sleeve 10 may be covered with an additional material, fabric, coating, and/or finish configured to either increase friction or decrease friction. In this manner, sleeve 10 may be configured to suitably interface with a variety of compression garments having varying frictional and/or material characteristics, as desired.
In certain exemplary embodiments, sleeve 10 may be configured with various trenches, zig-zags, and/or other surface geometries configured to allow sleeve 10 to expand and/or contract in an accordion-like manner. By configuring sleeve 10 in an expansible fashion, sleeve 10 may be better suited to compress the toe area of a compression garment 50, while still being able to expand sufficiently to evert around the greater circumferences associated with the upper portions of a limb, such as an upper leg.
In various exemplary embodiments, sleeve 10 may be integrated with and/or incorporated directly into a proximal aspect of compression garment 50. When donning and/or doffing compression garment 50, sleeve 10 may first be filled with fluid in order to facilitate the eversion process. Sleeve 10 may then be drained, for example while the patient wears compression garment 50, or after compression garment 50 has been removed from a limb. Additionally, when incorporated with a compression garment 50, sleeve 10 may comprise a sheet of gel incorporated into the proximal aspect of compression garment 50. When compression garment 50 is doffed, the sheet of gel rolls with and about compression garment 50, resulting in a similar combination of fluidity and garment layering as may be achieved with a separate sleeve 10. The sheet of gel may also be filled with fluid and/or drained, for example in order to aid in donning and doffing, to refine the size requirements for a specific limb to compression garment ratio, and/or the like.
In various exemplary embodiments disclosed herein, sleeve 10 is configured for use with compression garment 50. More broadly, sleeve 10 may be configured to convey any suitable generally tubular material onto a surface via an eversion process. Sleeve 10 may thus be sized, shaped, and/or configured in any appropriate manner, and the examples related to conveying a compression garment over a limb are provided by way of illustration and not of limitation.
Yet further, in various exemplary embodiments sleeve 10 may be utilized in a variety of industrial processes and apparatuses. For example: (i) sleeve 10 may be utilized in connection with gluing or affixing a material on a tubular or otherwise irregular shape when a conveyance of the material is warranted. Additionally, (ii) when sleeve 10 is encased, sleeve 10 can function as a powerful bearing mechanism. Yet further, (iii) when utilized with a strapping mechanism, sleeve 10 provides a reciprocal conveyance mechanism that is outstanding for traction and/or entrapment. For example, sleeve 10 may be conveyed onto a limb or object by rolling the outside, but as the straps are pulled from the inside, sleeve 10 generates a resultant force opposite to the direction of pull, resisting removal from the limb or object. Moreover, (iv) when encased in a structure where the two openings in sleeve 10 are affixed to the frame of the structure at opposite ends and one part of the structure is moved relative to the other, sleeve 10 generates a gripping force that rivals suction cups. Sleeve 10 could be used in industry to grasp, hold or move objects, and sleeve 10 may be particularly well suited to grasping irregular objects where suction-based grasping is impractical and/or impossible.
In an exemplary embodiment, a method for donning a compression garment over a limb comprises providing a sleeve having a first opening, a second opening, an inner surface and an outer surface wherein the first opening, the inner surface and the second opening cooperate to define a passage through the sleeve for a limb, the inner surface and the outer surface being formed of and defined by a continuous flexible material; providing a plurality of longitudinally continuous and parallel raised lines which extend outwardly from the inner surface and the outer surface; providing a fluid within the continuous film of flexible material, the fluid comprising at least one of water, solutions of water, oil, air, foams, urethane, silicone, soap, or lubricant; providing a compression garment having at least one opening at one end thereof; providing a pole extending from a surface, the pole having a diameter equal to or less than the diameter of the passage; providing a strap; centering the strap on the pole opposite the surface, the strap being long enough so that both ends of the strap reach the surface; providing a suction device at one end of the pole, the suction device being adapted to removably affix the pole to the surface; sliding the at least one opening over the pole until the compression garment is fully extended over the pole; placing the second opening on the pole opposite the surface; sliding the sleeve over the pole whereby the continuous film of flexible material everts such that the inner surface becomes the outer surface at the second opening while the outer surface becomes the inner surface at the first opening; pulling the at least one opening into contact with the outer surface at the second opening once the sleeve reaches the at least one opening; lifting the sleeve away from the surface whereby the continuous film of flexible material everts such that the inner surface becomes the outer surface at the first opening while the outer surface becomes the inner surface at the second opening; tucking the at least one opening (and/or any level of the compression garment that is desired for fewer eversions) into the first opening when everting the compression garment off the pole; grasping the ends of the straps and lifting off the pole to cause the compression garment to evert until it is completely removed from the pole, the end of the compression garment opposite the at least one opening abutting the first opening; positioning the first opening over a patient's limb; rolling the sleeve up the patient's limb whereby the inner surface and the outer surface evert thereby leaving the compression garment on the limb; disengaging the at least one opening from the second opening; and rolling the sleeve back down the limb until removed from the limb.

The method may further comprise disengaging the compression garment from the sleeve.
In another exemplary embodiment, a method for donning and doffing a compression garment over a limb comprises providing a sleeve having a first opening, a second opening, an inner surface and an outer surface wherein the first opening, the inner surface and the second opening cooperate to define a passage through the sleeve for a limb, the inner surface and the outer surface being formed of and defined by a continuous flexible material; providing a plurality of longitudinally continuous and parallel raised lines which extend outwardly from the inner surface and the outer surface; providing a fluid within the continuous flexible material, the fluid comprising at least one of water, solutions of water, oil, air, foams, urethane, or silicone; providing a compression garment having at least one opening at one end thereof; providing a pole extending from a surface, the pole having a diameter equal to or less than the diameter of the passage; providing a strap, centering the strap on the pole opposite the surface, the strap being long enough so that both ends of the strap reach the surface; providing a suction device at one end of the pole, the suction device being adapted to removably affix the pole to the surface; sliding the at least one opening over the pole until the compression garment is fully extended over the pole; placing the second opening on the pole opposite the surface; sliding the sleeve over the pole whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the second opening while the outer surface becomes the inner surface at the first opening; pulling the at least one opening into contact with the outer surface at the second opening once the sleeve reaches the at least one opening; lifting the sleeve away from the surface whereby the continuous film of flexible material everts such that the inner surface becomes the outer surface at the first opening while the outer surface becomes the inner surface at the second opening, tucking the at least one opening into the first opening when everting the compression garment off the pole; grasping the ends of the straps and lifting off the pole which causes the compression garment to evert until it is completely removed from the pole, the end of the compression garment opposite the at least one opening abutting the first opening; positioning the first opening over a patient's limb; rolling the sleeve up the patient's limb whereby the inner surface and the outer surface evert thereby leaving the compression garment on the limb; disengaging the at least one opening from the second opening; rolling the sleeve back down the limb until removed from the limb; sliding at least one opening over the limb until the compression garment is fully extended over the limb; placing the first opening on the limb; sliding the sleeve over the limb whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the first opening while the outer surface becomes the inner surface at the second opening; pulling the at least one opening into contact with the outer surface at the first opening once the sleeve reaches the at least one opening; tucking the at least one opening into the second opening when everting the compression garment off the limb; lifting the sleeve away from the surface whereby the continuous flexible material everts such that the inner surface becomes the outer surface at the second opening while the outer surface becomes the inner surface at the first opening, the lifting continuing until the compression garment is completely removed from the limb, the end of the compression garment opposite the at least one opening abutting the second opening; and disengaging the compression garment from the sleeve.
