DETAILED DESCRIPTION OF THE INVENTION
While the glove disclosed herein may be embodied in many different forms, there are described in detail herein specific embodiments of the glove. This description is an exemplification of the principles of the glove and is not intended to limit the glove to the particular embodiments illustrated.
For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated, and the reference numerals indicate elements shown in the figures.
As used in this application, “wearer” refers to a human. As used in this application, a “hand” is the terminal part of the human arm located below the forearm consisting of the wrist, palm, four fingers, and an opposable thumb.
The term “width,” as used herein in reference to any element of the glove 2 or a wearer, is measured in the direction extending from the open end 6 to the closed end 4 of the glove 2 (see e.g. width W in FIG. 1); “perimeter length” or “length” as used herein in reference to any element of the glove 2 or a wearer is measured in the direction extending around the glove 2 (see e.g. length “P” in FIG. 3 and length “L” in FIG. 6).
A glove 2 as shown in the figures can be used for medical purposes, such as examination or surgery, or for non-medical purposes, such as in the laboratory, and elsewhere. Hereinafter the glove 2 is referred to as a medical glove. In at least one embodiment, the medical glove 2 is sized to fit a wearer's hand. The medical glove 2 has a closed end 4, an open end 6, an outer surface 8, and an inner surface 10. The open end 6 of the medical glove 2 provides an entry point for the wearer's hand. Thus the inner surface 10 defines a cavity 12 that is sized for the wearer's hand. The medical glove 2 can be right handed, left handed, or ambidextrous. The medical glove 2 can be considered to have two “sides” with one side being adjacent to a palm of the wearer's hand (hereinafter the palm side) and the other side being adjacent to the back of the wearer's hand (hereinafter the back side).
The medical glove 2 is formed of glove material 14 and includes a glove body 16 and a cuff 20. In some embodiment, the glove body 16 is made of one layer 13a of glove material 14. The glove body 16 includes five fingers 18 at the closed end 4 of the medical glove 2. The five fingers 18 enclose the four fingers and thumb of the wearer's hand. In some embodiments, when the medical glove 2 is worn by the wearer, the glove body 16 encloses the wearer's hand. In other embodiments, when the medical glove 2 is worn by the wearer, the glove body 16 encloses the wearer's hand and at least a portion of the wearer's forearm adjacent to the hand.
The cuff 20 forms, and extends from, the open end 6 of the medical glove 2. In at least one embodiment, the cuff 20 extends from the glove body 16. In some embodiments, when the medical glove 2 is being worn, the cuff 20 encloses at least a portion of the wearer's wrist. As shown in FIGS. 1 and 3, the cuff 20 has a width (W) and a perimeter length (P) that extends about the entire perimeter of the cuff 20. The width (W) of the cuff 20 is from 0.4 inches to 0.6 inches, or from 1.0 cm to 1.5 cm. In at least one embodiment, the width (W) of the cuff 20 is less than the width of the wearer's wrist. The cuff 20 can be described as being positioned a distance away from the wearer's hand. In some embodiments, the cuff 20 covers a portion of the forearm when the medical glove 2 is worn by the wearer. The perimeter length (P) of the medical glove 2 at the cuff 20 is sized for the wearer's wrist and/or forearm.
As shown in FIGS. 3-5, the cuff 20 is made of two layers 13a,b of glove material 14, and has a first end 22 and a second end 30. As shown in the figures, the second 30 of the cuff 20 has a substantially straight configuration. However, the second end 30 can have other configurations, e.g. wavy, or zig-zagged, or any other suitable configuration.
The glove material 14 can be considered as comprising a first section that forms the glove body 16 and a portion of the cuff 20, and a second section that forms another portion of the cuff 20. The layers 13a,b of glove material 14 forming the cuff 20 are adjacent to one another. The layers 13a,b of glove material 14 forming the cuff 20 can be considered to be radially adjacent to one another relative to the cavity 12 of the medical glove 2. The inner surface 10 of the medical glove 2 is formed by the layer 13a of glove material 14 forming the glove body 16 and by the first layer 13a of glove material 14 forming the cuff 20. The outer surface 8 of the medical glove 2 is formed by the layer 13a of glove material 14 forming the glove body 16 and by the second layer 13b of glove material 14 forming the cuff 20.
In at least one embodiment, the first end 22 of the cuff 20 is a fold 22. As shown in the figures, the fold 22 is a portion of the layer 13 of glove material 14 that is bent over on itself (folded). In this embodiment, the fold 22 defines the open end 6 of the medical glove 2. The fold 22 can also be considered as forming a closed end of the cuff 20.
As shown in FIGS. 5-7, the two layers 13a,b of glove material 14 forming the cuff 20 are attached to one another at a plurality of locations 24 about the perimeter of the cuff 20. In some embodiments, the thickness of the cuff 20 is uniform. For example, as shown in FIG. 5, the thickness of the cuff 20 between the attachment locations 24 and at the attachment locations 24 is substantially the same. The cuff 20 shown in FIG. 5 can also be described as having a uniform, or a smooth or flat, exterior surface. In other embodiments, the thickness of the cuff 20 is non-uniform. For example, the thickness of the cuff 20 at the attachments locations 24 is less than the thickness of the cuff 20 between the attachment locations 24 (not shown). In this embodiment the exterior surface of the cuff 20 can be described as having a non-uniform, or an irregular or corrugated, surface.
In at least one embodiment, the locations 24 are offset from the open end of the medical glove 2. The locations 24 can also be described as being offset from the fold 22, or as being offset from the closed end of the cuff 20. As shown for example in FIG. 6, the locations 24 extend from the fold 22 and thus at least a portion of the location is offset from the fold 22. The two layers 13a,b of glove material 14 forming the cuff 20 can be attached to one another by any suitable means, including but not limited to, adhesive, heat bonding, stitching, hook and loop fasteners such as Velcro®, and combinations thereof Thus these locations 24 can be considered as “securement locations” or “attachment locations.” Hereinafter, attachment location will be used. As used in this application, the fold 22 is not considered to be an attachment location 24. The securement of the two layers of glove material to one another at an attachment location is optimally semi-permanent or permanent.
In some embodiments, the cuff 20 has two, three, four, five, or six attachment locations 24. In one embodiment, the cuff 20 has a minimum of four attachment locations. In some embodiments, the attachment locations 24 extend parallel to a long axis (not shown) of the cuff 2. This is shown for example in FIG. 6. In other embodiments, the attachment locations do not extend parallel to the long axis of the cuff (not shown). In some embodiments, the attachment locations 24 are parallel to one another. This is shown for example in FIG. 6. In other embodiments, the attachment locations 24 are not parallel to one another (not shown). In at least one embodiment, at least a portion of the attachment location 24 is offset from the fold 22. This is shown, for example, by the attachment locations 24 of FIGS. 6 and 7.
Each attachment location 24 has a width and a length sufficient to attach the two layers of glove material 14 forming the cuff 20 to one another. The width of the attachment location is at most equal to the width (W) of the cuff 20, as shown, for example, in FIG. 6. In some embodiments, the width of the attachment location 24 is equal to the width of the cuff 20. This is shown for example in FIG. 6. The attachment locations 24 in FIG. 6 can also be described as extending from the fold 22 or closed end of the cuff 20 or open end 6 of the medical glove 2 to the open end 30 of the cuff 20. In other embodiments, the width of the attachment location 24 is less than the width (W) of the cuff 20. Non-limiting examples of attachment locations 24a, 24c having a width less than the width of the cuff are provided in FIG. 7. The length (L2) of the attachment location 24 is less than the perimeter length (P) of the cuff 20. In some embodiments, the length of the attachment location is uniform. This is shown for example by the attachment locations 24 in FIG. 6 and by location 24a in FIG. 7. In other embodiments, the length of the attachment location 24 is non-uniform. This is shown for example by location 24c in FIG. 7. In some embodiments, the length of the attachment location is from 0.40 inches to 3 inches, or from 1.0 cm to 7.62 cm.
Each attachment location 24 has a configuration based on the characteristics of the width and length of the attachment location 24. In some embodiments, each attachment location 24 of a medical glove 2 has the same configuration. For example, as shown in FIG. 6, the attachment locations 24a, 24b have the same configuration. In other embodiments, the attachment locations 24 of a medical glove 2 have different configurations. For example, as shown in FIG. 7, the attachment locations 24a, 24b, 24c have different configurations from one another.
The attachment locations 24 are separated one from another by a length (L1) and adjacent locations define an opening 28 in the cuff 20 which leads to the space 26 between the two layers of glove material 14 forming the cuff 20. The opening 28, shown by way of example in FIG. 4, is adjacent to, and only accessible from, the outer surface 8 of the medical glove 2.
In at least one embodiment, the length (L1) between two adjacent attachment locations 24, and thus the length of the opening 28, is sized to receive a human finger. In at least one embodiment, the attachment locations 24 are equidistant from one another about the perimeter of the cuff 20. In some embodiments, two attachment locations 24 are located on the palm side of the medical glove 2 and two attachment locations 24 are located on the back side of the medical glove 2. In one embodiment, one opening 28 is located on the palm side of the medical glove 2 and one opening 28 is located on the back side of the medical glove 2. In some embodiments, the length (L1) between two adjacent attachment locations 24 is from 0.40 inches to 0.80 inches, or from 1.0 cm to 2.0 cm. Thus, in these embodiments, the opening 28 has a length from 0.40 inches to 0.80 inches, or from 1.0 cm to 2.0 cm. In other embodiments, the length (L1) between two attachment locations 24 is equal to one quarter of the perimeter length (P) of the cuff 20. In still other embodiments, the length (L1) between two attachment locations is equal to one fifth of the perimeter length (P) of the cuff 20.
The cuff 20 can also be described as having a plurality of first portions 24 where the two layers 13a,b of material 14 forming the cuff 20 are attached to one another; and a plurality of second portions 32a, 32b, and 32c where the two layers 13a,b of material 14 forming the cuff 20 are separated from one another and define an opening 28 accessible from outside the glove body 16. The cuff 20 can also be described as having a plurality of closed regions 24 and a plurality of open regions 28 with each open region 32a, 32b, and 32c being between two closed regions 24. In some embodiments, the second portion or open region has three closed sides and one open side that forms a portion of the second end 30 of the cuff 20; and the first portion or closed region 24 has four closed sides.
In at least one embodiment, the wearer can remove the medical glove 2 by inserting a finger into an opening 28 of the cuff 20 and using the finger to move the cuff 20 towards the wearer's fingers 18. In one embodiment, this method of removal prevents contamination of the wearer's wrist as the medical glove 2 is being removed.
In some embodiments, a medical glove 2 is made by providing a glove made of a layer 13a of material 14 defining an open end; folding the layer 13a of glove material 14 at the open end to form a cuff 20 with a fold 22, where the fold 22 defines the open end 6 of the medical glove 2 and the cuff has two layers 13a,b of glove material 14; securing the two layers 13a,b of glove material 14 of the cuff 20 to one another at a plurality of attachment locations 24. In some embodiments, the method further comprises applying heat to the fold 22. This can help set the fold 22. The two layers 13a,b of glove material 14 may be secured by any suitable method, including but not limited to, an adhesive, heat bonding, stitching, and combinations thereof.
In other embodiments, a medical glove 2 is made by forming a glove made of a layer 13a of glove material 14 defining an open end; folding the layer 13a of glove material 14 at the open end to form a cuff 20 with a fold 22, where the fold 22 defines the open end 6 of the medical glove 2 and the cuff 20 has two layers 13a,b of glove material 14; securing the two layers 13a,b of glove material 14 of the cuff 20 to one another at a plurality of attachment locations 24. In some embodiments, the method further comprises applying heat to the fold 22. This can help set the fold 22. The two layers 13a,b of glove material 14 may be secured by any suitable method, including but not limited to, an adhesive, heat bonding, stitching, hook and loop fasteners such as Velcro®, and combinations thereof. The securement of the two layers of glove material to one another at an attachment location is optimally semi-permanent or permanent.
In at least one embodiment, the glove material 14 is an elastomeric material. Materials suitable for the glove material 14 include, but are not limited to, latex, rubber, nitrile, neoprene, vinyl, and combinations thereof.
In at least one embodiment, at least one of the surface 8, 10 of the medical glove 2 includes an optional surface treatment, such as coating or finish. In some embodiments, the inner surface 10 has an optional surface treatment and the outer surface 8 has no surface treatment. In other embodiments, the inner and outer surfaces 8, 10 each have an optional surface treatment. In one embodiment, the optional surface treatment is the same for the inner surface 10 and the outer surface 8. In another embodiment, the inner surface 10 has a different optional surface treatment than the outer surface 8. In at least one embodiment, the surface treatment is optionally a coating or layer of powder. Examples of a powder includes, but not limited to, modified cornstarch or calcium carbonate.
In some embodiments, the medical glove 2 is sterile. In other embodiments, the medical glove 2 is not sterile. In at least one embodiment, the medical glove 2 is disposable. In some embodiments, the medical glove 2 is reusable.
