The material can include a weave (110,210) of untwisted, continuous filament polyester. The material can also include a carbon filament (209,211). The seam is sealed by applying a tape (300,400) across the seam and applying heat to cause the tape to attach to the weave.

Description

BACKGROUND

Technical Field

This disclosure relates generally to fabrics, and more particularly to gowns.

Background Art

Medical professionals frequently interact with patients who have communicable diseases. When treating such patients, the medical professional must take care not become infected or ill due to the microorganisms or pathogens related to the disease. This is frequently accomplished by donning a medical gown. These medical gowns are sometimes referred to as an “isolation gown.”
One problem associated with prior art medical gowns involves their construction. When multiple parts of the gown are sewn together, the resulting seam can act as a pathway for pathogens and other infections substances to pass through the medical gown. Such pathways put the medical services provider at risk of becoming ill. It would be advantageous to have a gown that overcomes some of the issues associated with prior art medical gowns.

DETAILED DESCRIPTION OF THE DRAWINGS

Embodiments of the disclosure are now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.” Relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, reference designators shown herein in parenthesis indicate components shown in a figure other than the one in discussion. For example, talking about a device (10) while discussing figure A would refer to an element, 10, shown in figure other than figure A.
Embodiments of the present disclosure provide methods of constructing a gown or other garment with sealed seams. The sealing of the seams serves to protect a medical professional or other user from coming into contact with pathogens and microorganisms carrying communicable diseases. As medical professionals generally interact with patients with their hands and arms, rather than other parts of their bodies, the inclusion of sealed sleeves in a medical gown eliminates a large majority of pathways between the patient and medical professional. This is true even when the sleeves are sewn or otherwise joined to a body covering portion.
In one embodiment, the method includes constructing a seam by sewing two pieces of material together. In one embodiment, the seam is a “lay flat” seam joined by a stitch that runs substantially parallel to the material being joined. In one embodiment, the material sewn together to form the gown or other garment is woven. In one embodiment, the material is a weave of untwisted, continuous filament polyester. In another embodiment, the material is a weave of untwisted, continuous filament polyester that also includes a carbon filament. For example, in one embodiment the material is about 99% woven polyester and about 1% carbon filament. The carbon filament provides a dual function of both rendering the material less susceptible to discharge and conduction of static electricity, but also provides a unique bonding element for tape that can be used to seal the seams.
Once the seam is constructed, in one embodiment a sealing tape can be applied across the seam. In one embodiment, the tape is manufactured from a weave of untwisted, continuous filament polyester, with an adhesive layer disposed thereon. In another embodiment, the tape is manufactured from a weave of untwisted, continuous filament polyester comprising a carbon filament, with an adhesive layer disposed thereon.
Once the tape is applied to the seam, heat can then be applied to the sealing tape to cause it to adhere to the woven material and/or the carbon filament disposed therein, where the carbon filament is included. While sealing tapes have been used in other applications, they generally require a laminated material that includes an interior membrane. Said differently, with prior art sealing techniques, the material to be sealed requires an inner layer and an outer layer of fabric that have disposed therebetween a membrane layer. The inner and outer layers are knit layers so that they can yield under thermal stimulus to allow the tape to penetrate one of the fabric layers so as to reach the membrane layer. When heat is applied to the tape, the tape “adheres” to the membrane layer. Prior art tapes will not adhere to fabric layers. Embodiments of the present invention eliminate the need for a sandwiched membrane layer by employing woven—rather than knit—materials that include a carbon filament disposed therein. Advantageously, embodiments of the disclosure provide a lower cost garment that is easier to manufacture and more comfortable for the wearer, all while providing the necessary barrier protection levels to keep the medical personnel using the gown safe from contaminants.
Turning now to FIG. 1, illustrated therein is one embodiment of a material 100 suitable for use with one or more embodiments of the disclosure. The material 100 is illustratively shown as a sheet 112. As shown in FIG. 1, the illustrative material 100 is a woven material. In one embodiment, the material 100 comprises a one-ply weave 110. In another embodiment, the material 100 comprises a two-ply weave. An expanded view of a section of the sheet 112 is also shown to highlight the woven nature of the material 100.
In one embodiment, the material 100 includes warps 101,102,103,104 and wefts 105,106,107,108. The warps 101,102,103,104 are elements of the weave 110 that run vertically in the view of FIG. 1, while the wefts 105,106,107,108 run horizontally. Note that while the terms “warps” and “wefts” are used illustratively to describe the weave 110, those of ordinary skill in the art having the benefit of this disclosure will note that alternate terms, such as “warp threads,” or “warp yarns” can be substituted for “warps.” Similarly, “weft fill” or “weft threads” can be substituted for “wefts.”
In one embodiment, the weave 110 of the material 100 is a taffeta weave. A “taffeta” weave is a style of weave where the threads forming the wefts 105,106,107,108 and warps 101,102,103,104 intertwine alternatively to produce the checkerboard effect shown in sectional view as weave 110. In the illustrative embodiment of FIG. 1, the warps 101,102,103,104 and wefts 105,106,107,108 are each substantially parallel to other warps 101,102,103,104 and wefts 105,106,107,108, respectively. The warps 101,102,103,104 of this illustrated embodiment are substantially perpendicular to the wefts 105,106,107,108.
In one or more embodiments, the warps 101,102,103,104 and wefts 105,106,107,108 each comprise untwisted, continuous filament polyester. The use of untwisted, continuous filament polyester in a taffeta weave provides an exceptional barrier layer that is highly-fluid resistant. Moreover, the use of untwisted, continuous filament polyester as the warps 101,102,103,104 and wefts 105,106,107,108, when the warps 101,102,103,104 and wefts 105,106,107,108 are arranged in a taffeta weave, advantageously offers a high-density construction that resists fluid penetration while maintaining breathability and comfort. In one embodiment, the weave 110 contains about 8700 filaments per square inch. In one embodiment, the weave 110 of untwisted, continuous filament polyester warps 101,102,103,104 and wefts 105,106,107,108 results in a material 100 that can withstand 75 or more cleaning processings without degradation in its fluid-resistant characteristics. In one embodiment, the density of warps 101,102,103,104 and wefts 105,106,107,108 results in a 2.2-ounce polyester weave 110. In another embodiment, the density of warps 101,102,103,104 and wefts 105,106,107,108 results in a 2.6-ounce polyester weave 110.
In contrast to the weave 110 shown in FIG. 1, most prior art gowns with sealed seams use knit fabrics that sandwich a membrane layer. As is known in the art, knit fabrics are produced on large knitting machines that “knit” different yarns together. Knit fabrics are generally manufactured from one continuous thread in contrast to the two threads shown in FIG. 1 that form the warps 101,102,103,104 and wefts 105,106,107,108, respectively. Disadvantageously, knit fabrics stretch and offer very poor fluid penetration resistance. This is one of the reasons that the membrane layer is required. By contrast, the taffeta weave of the material 100 of FIG. 1 can be used to construct lightweight, comfortable gowns or other garments featuring a single-ply, liquid and pathogen resistant layer. Moreover, the material 100 of FIG. 1 does not stretch as do knitted fabrics.
While untwisted, continuous filament polyester is one material that can be used for the warps 101,102,103,104 and wefts 105,106,107,108, others will be obvious to those of ordinary skill in the art having the benefit of this disclosure. For example, in one embodiment synthetic materials other than polyester may be utilized where the synthetic material is capable of being configured into a taffeta weave.
In one embodiment, the material 100 is characterized by a comparatively higher tensile strength than materials that use non-synthetic materials, such as cotton, wool, silk, or blends, such as cotton-polyester or other blended materials. The higher tensile strength is due to the use of untwisted, continuous filament polyester for both the warps 101,102,103,104 and wefts 105,106,107,108. It should be noted that in one embodiment the material 100 is also lighter than fabrics using natural or blended materials as well. As noted above, the use of untwisted, contiuous filament polyester also allows the material 100 to be subjected to numerous laundry cycles without destroying its fluid barrier properties, its brightness, or its color. As will be noted below, in one or more embodiments the material 100 can be color-coded to indicate size of gowns made from the material 100. Accordingly, resistance to color change can be an advantageous property. In one embodiment, the material 100 maintains its fluid barrier properties through at least 75 institutional laundry cycles and in some instances after at least 125 cycles.
The fact that the material 100 is washable in one embodiment is advantageous. For example, when used to create garments, the user of the garments may face the choice between disposable textiles and reusables. This choice can be daunting. However, the reusable nature of the material 100 can advantageously reduce waste. For example, when the material 100 is used to create surgical gowns, experimental testing has shown that use of the material 100 can result in a waste reduction from one operating room by an average of 65 percent. This reduction in waste results in lower disposal costs. In addition, while it may seem as though cleaning reusable textiles would expend large amounts of energy and water, modern equipment and engineering keep energy use low and use water efficiently. Finally, the material 100 is also low-linting and comfortable.
Turning now to FIG. 2, illustrated therein is an alternate material 200 suitable for use with one or more embodiments of the disclosure. Once again, the material 200 is illustratively shown as a sheet 212. In this illustrative embodiment, the material 200 is a woven material. In one embodiment, the material 200 comprises a one-ply weave 210. In another embodiment, the material 200 comprises a two-ply weave. An expanded view of a section of the sheet 212 is also shown to highlight the woven nature of the material 200.
In one embodiment, the material 200 includes warps 201,202,203,204 and wefts 205,206,207,208. In one embodiment, the weave 210 of the material 200 is a taffeta weave. In the illustrative embodiment of FIG. 2, the warps 201,202,203,204 and wefts 205,206,207,208 are each substantially parallel to other warps 201,202,203,204 and wefts 205,206,207,208, respectively. The warps 201,202,203,204 of this illustrated embodiment are substantially perpendicular to the wefts 205,206,207,208.
In one or more embodiments, the warps 201,202,203,204 and wefts 205,206,207,208 each comprise untwisted, continuous filament polyester. As noted above, the use of untwisted, continuous filament polyester in a taffeta weave provides an exceptional barrier layer that is highly-fluid resistant. Moreover, the use of untwisted, continuous filament polyester as the warps 201,202,203,204 and wefts 205,206,207,208, when the warps 201,202,203,204 and wefts 205,206,207,208 are arranged in a taffeta weave, advantageously offers a high-density construction that resists fluid penetration while maintaining breathability and comfort. In one embodiment, the weave 210 contains about 8700 filaments per square inch. In one embodiment, the weave 210 of untwisted, continuous filament polyester warps 201,202,203,204 and wefts 205,206,207,208 results in a material 200 that can withstand 75 or more cleaning processings without degradation in its fluid-resistant characteristics. In one embodiment, the density of warps 201,202,203,204 and wefts 205,206,207,208 results in a 2.2-ounce polyester weave 210. In another embodiment, the density of warps 201,202,203,204 and wefts 205,206,207,208 results in a 2.6-ounce polyester weave 210.
While untwisted, continuous filament polyester is one material that can be used for the warps 201,202,203,204 and wefts 205,206,207,208, others will be obvious to those of ordinary skill in the art having the benefit of this disclosure. For example, in one embodiment synthetic materials other than polyester may be utilized where the synthetic material is capable of being configured into a taffeta weave.
In one embodiment, the material 200 is characterized by a comparatively higher tensile strength than materials that use non-synthetic materials, such as cotton, wool, silk, or blends, such as cotton-polyester or other blended materials. The higher tensile strength is due to the use of untwisted, continuous filament polyester for both the warps 201,202,203,204 and wefts 205,206,207,208. It should be noted that in one embodiment the material 200 is also lighter than fabrics using natural or blended materials as well.
In this illustrative embodiment, the weave 210 also includes a carbon filament 209,211.
The carbon filament 209,211 can be configured as a weft, as a warp, or both. In the illustrative embodiment of FIG. 2, carbon filament 209 is configured as a weft while carbon filament 211 is configured as a warp.
In one embodiment, the material 200 is about 99% untwisted, continuous filament polyester and about 1% carbon filament by weight. The term “about” is used herein to refer to a specification inclusive of manufacturing tolerances. For example, if the tolerance was 99% polyester by weight, with a manufacturing tolerance of plus or minus 2%, both 96.4% and 101.8% would be “about” 99%.
Turning now to FIG. 3, illustrated therein is one embodiment of a tape 300 suitable for sealing seams in accordance with one or more embodiments of the disclosure. In one embodiment, the tape 300 comprises a layer 301 of the material 100 of FIG. 1, which comprises a one-ply weave of material comprising warps and wefts woven into a taffeta weave. In one or more embodiments, the warps and wefts each comprise untwisted, continuous filament polyester.
As the layer 301 of the material 100 defined by the warps and wefts is porous, in one or more embodiments the pores of the layer 301 of material 100 are filled with a cured or partially cured thermosetting adhesive 302 on one side. In other embodiments, the partially cured thermosetting adhesive 302 will be omitted. Bonded to cured or partially cured thermosetting adhesive 302, or alternatively directly to the layer 301 of material 100 when the thermosetting adhesive 302 is omitted, is a layer of thermoplastic hot melt adhesive 303.
Turning now to FIG. 4, illustrated therein is another embodiment of a tape 400 suitable for sealing seams in accordance with one or more embodiments of the disclosure. In one embodiment, the tape 400 comprises a layer 401 of the material 200 of FIG. s, which comprises a one-ply weave of material comprising warps and wefts woven into a taffeta weave, and also including a carbon filament as previously described. In one or more embodiments, the warps and wefts each comprise untwisted, continuous filament polyester.
As the layer 401 of the material 200 defined by the warps, wefts, and carbon filament is porous, in one or more embodiments the pores of the layer 401 of material 200 are filled with a cured or partially cured thermosetting adhesive 302 on one side. In other embodiments, the partially cured thermosetting adhesive 302 will be omitted. Bonded to cured or partially cured thermosetting adhesive 302, or alternatively directly to the layer 401 of material 200 when the thermosetting adhesive 302 is omitted, is a layer of thermoplastic hot melt adhesive 303.
Turning now to FIG. 5, illustrated therein is one explanatory seam sealing apparatus 500 suitable for sealing the tape 300 of FIG. 3, or alternatively the tape 400 of FIG. 4, to a seam formed by sewing two layers of material (100) or material (200) together. The apparatus 500 is described in further detail in U.S. Pat. No. 6,887,335, which is incorporated herein by reference. The apparatus 500 can be used to guide a seam having tape 300, or alternatively tape 400, disposed therein so as to thermally cause the tape 300,400 to either the warps and wefts of either material (100) or material (200), or alternatively directly to the carbon filament (209,211) of material (200).
As shown in FIG. 3, the apparatus 500 includes a roll 501 of the tape 300,400 mounted thereon. The tape 300,400 is fed into a sealer 502 that includes an upper roller, tape guides, and an actuator. The sealer 502 can be lowered according to predetermined settings to effect advancement of the tape 300,400 and material (100,200) being fed into the sealer 502. A drive mechanism can drive the rollers to feed the tape 300,400 and material (100,200) through the sealer 502.
A hot air gun 503 provides heat to the tape 300,400 to adhere it to the carbon filament (209,211) of the material (200) as it passes through the sealer 502. Alternatively, the hot air gun 503 can work to heat the tape 300,400 to adhere it to the warps and wefts where the carbon filament is omitted.
A heated air supply feeds the hot air gun 503, which directs the heated air into the consolidation nip and to the tape 300,400 on demand. In effect, the hot air gun 503 blows the hot air along the tape 300,400 as it passes through the sealer 502 while disposed upon a seam. It should be noted that other embodiments, the hot air gun 503 can be replaced with a hot roller, which passes over the tape 300,400 to seal it to the warps and wefts of material (100) and/or carbon filament (209,211) of material (200). In yet another embodiment, the hot air gun 504 can be replaced with a hot press, which can be applied to the tape 300,400 to seal it to the warps and wefts of material (100) or to the carbon filament (109,211) of material (200).
Turning now to FIG. 6, illustrated therein is one embodiment of a “lay down” seam 600 constructed in accordance with one or more embodiments of the disclosure. In one embodiment, a first flap 601 from a first layer 602 of material is folded back upon the layer 602, while a first flap 603 from a second layer of material 604 is folded back upon the layer 604. A stitch 605 is then applied at the folds 606,607 between the flaps 601,603 and the layers 602,604. In one embodiment, the stitch 605 is a horizontal stitch that runs parallel to both the first layer 602 and the second layer 604.
As shown in FIG. 7, the first flap 601 and the second flap 603 can then be folded down to “lay flat” upon the first layer 602 and the second layer 604, respectively. In one embodiment, an optional safety stitch 701,702 can be applied to hold the first flap 601 and the second flap 603 flat upon the first layer 602 and the second layer 604, respectively.
Turning now to FIG. 8, illustrated therein is a work piece 800 suitable for feeding into the sealer (502) of the apparatus (500) of FIG. 5. As shown in FIG. 8, a seam 801 is first constructed by sewing two layers 802,803 of either material (100) or material (200) together. In the illustrative embodiment of FIG. 8, the seam 801 comprises a lay flat seam as described above with reference to FIGS. 6 and 7. However, other seams could be used as well. Illustrating by example, in another embodiment a double-C interlocking seam can be used where a first C is formed by folding a section of the first layer 802 of material back over itself, while a second C is constructed by folding a section of the second layer 803 of material back over on itself. The two Cs can then interlocked, with stitching applied to the double-C interlocking seam. Other types of seams will be obvious to those of ordinary skill in the art having the benefit of this disclosure.
Regardless of the type of seam 801 that is created, once the seam 801 is formed, in one or more embodiments tape 300,400 can then be placed across the seam 801.
Where carbon filament (209,211) is used in the material (200), the tape 300,400 can be thermally affixed to the carbon filament (209,211) of the material 200 in a variety of ways. In one embodiment, a hot air gun 503 blows the hot air along the tape 300,400 to seal the tape 300,400 to the carbon filament (209,211). In another embodiment, a hot roller 810 passes over the tape 300,400 to seal it to the carbon filament (209,211) of the material (200). In yet another embodiment, a hot press 811 can be applied to the tape 300,400 to seal it to the carbon filament (209,211) of the material (200).
Turning now to FIG. 9, illustrated therein is a sealed seam 900. As shown in FIG. 9, the tape 300,400 has become thermally affixed 901 to at least one carbon filament (209,211) of the material (200). The tape 300,400 covers the entirety of the seam 801, thereby creating a liquid and contaminant impenetrable barrier along the seam 801.
Turning now to FIG. 10, illustrated therein is illustrated therein is a protective garment 1000, shown in pattern form, and configured in accordance with one or more embodiments of the disclosure. For ease of illustration, the illustrative protective garment 1000 shown throughout the views is configured as a medical gown. However, it will be clear to those of ordinary skill in the art having the benefit of this disclosure that the protective garment 1000 could be configured in accordance with the needs of other professions, applications, and requirements. A medical gown is merely one explanatory embodiment.
A body covering portion 1001 is configured to wrap about the torso of a wearer. In one embodiment, the body covering portion 1001 is manufactured from a woven fabric, such as the material 100 of FIG. 1 or the material 200 of FIG. 2. Where a woven material is used, body covering portion 1001 can be configured for laundering and reuse. One or more antimicrobial layers can be added to further enhance antimicrobial protection. In one embodiment, the length 1013 of the body covering portion 1001 is configured to run from at least a wearer's shoulder to below their knee.
A first sleeve 1002 and a second sleeve 1003 extend distally from the body covering portion 1001. The first sleeve 1002 and the second sleeve 1003 are configured to receive wearer's arms when the protective garment 1000 is donned. As will be described below, one or both of the first sleeve 1002 and the second sleeve 1003 can comprise a sealed seam 900 like the one described above with reference to FIG. 9.
The protective garment 1000 may optionally include pockets or other surface features. A front portion of the body covering portion 1001 is configured to be placed against the front of the torso of a wearer. The body covering portion 1001 then wraps around and terminates behind the wearer in one embodiment.
In one embodiment, the material 100, or alternatively material 200, and its sealed seams 900 can be configured to meet the PB70 Standard of the Association for the Advancement of Medical Instrumentation (AAMI). For example, the material 100,200 and its sealed seams 900 may have a moisture vapor transmission rate (MVTR) that allows for comfort during wearing while still meeting the Spray impact test (AATCC42), Hydrostatic Pressure testing (AATCC127) and Viral Penetration testing (ASTM-F1671) guidelines. For medical applications the material 100,200 and sealed seams 900 each have properties that prevent contaminants from passing through to the care giver. For example the protective garment 1000 can include a layer of the material 100,200 and a sealed seam 900 that is sealed by a layer of tape (300,400) that is thermally attached to the weave (110,210) of the material 100,200 so as to have vapor and moisture barrier characteristics that may be required by an applicable AAMI level. This allows the protective garment 1000 to perform as an infection protection measure.
Turning now to FIG. 11, a health care services provider 1100 is shown wearing one embodiment of a medical gown 1101 configured in accordance with one or more embodiments of the disclosure. The illustrative medical gown 1101 includes a layer of material 100,200 that includes a weave (110,210) of untwisted continuous filament polyester, and optionally carbon filament as well. One or more seams 1102,1103,1104,1105,1106,1107 are disposed along the medical gown 1101. In one embodiment, each seam 1102,1103,1104,1105,1106,1107 comprises a lay flat seam.
As shown in the exploded view 1108 of seam 1107, in one embodiment the seam 1107 is sealed by a tape 300,400 that is thermally attached to the weave (110,210) of the material 100,200. In one embodiment, the seam 1107 is sealed to form a AAMI-PB70 Level-3 seal.
In one or more embodiments, the medical gown 1101 is color-coded for size. For example, a ciel blue gown may be a large, while a white gown is extra large, a green gown is extra-extra large, and so forth. In another embodiment, the medical gown 1101 has a common color across all sizes, with only the collar and/or cuffs being color coded to indicate size. Other color combinations will be obvious to those of ordinary skill in the art having the benefit of this disclosure.
Turning now to FIG. 12, illustrated therein is one explanatory method 1200 for sealing the seam of a medical gown configured in accordance with one or more embodiments of the disclosure. At step 1201, a seam is constructed by sewing two layers of material together. In one embodiment, each layer of material comprises a weave of untwisted continuous filament polyester. The layer of material can optionally include carbon filament. In one embodiment, the seam comprises a lay flast seam, although other seams will be obvious to those of ordinary skill in the art having the benefit of this disclosure.
At step 1202, a layer of tape is applied along the seam. The tape can either be the tape (300) of FIG. 3 or the tape (400) of FIG. 4 in one or more embodiments. At step 1203, heat is provided to the tape, thereby causing the tape to adhere to the weave. In one embodiment, the heat is provided to cause the tape to adhere to a carbon filament of the weave. The heat can be provided in one of a variety of ways at step 1203. In one embodiment, the provision of heat comprises blowing hot air along the tape. In another embodiment, the provision of heat comprises passing a hot roller along the tape. In yet another embodiment, the provision of heat comprises applying a hot press to the tape.
In the foregoing specification, specific embodiments of the present disclosure have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the present disclosure as set forth in the claims below. Thus, while preferred embodiments of the disclosure have been illustrated and described, it is clear that the disclosure is not so limited. Numerous modifications, changes, variations, substitutions, and equivalents will occur to those skilled in the art without departing from the spirit and scope of the present disclosure as defined by the following claims. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present disclosure. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims.
