[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62 / 674,876, filed May 22, 2018, the entire contents of which are incorporated herein by reference.

[0002] FIELD OF THE DISCLOSURE The examples disclosed herein relate generally to wearable surgical garments, and more particularly to self-adjustable surgical garments and methods of adjusting the same. [Background technology]

[0003] In surgery, it is common practice for all personnel in the operating room to wear surgical attire for sterile purposes, including overhead gowns, tie-close gowns, and zip-up gowns.

[0004] In a typical surgical procedure, the first person entering the operating room puts on and adjusts the surgical gown, then helps the other person adjust the surgical gown. This must be done without both hands leaving the area corresponding to the sterile zone. To prevent compromising the sterility of the surgical gown and the wearer, various techniques are used, such as the use of tie cards and / or partner techniques. In one example, the first person entering the operating room waits for the second person to help adjust the surgical gown. Typically, the second person stands behind the first wearer and adjusts the straps with or without the use of tie cards to secure the first wearer's surgical gown. The first wearer then helps the second wearer adjust the surgical gown. This technique is repeated until everyone in the operating room has put on and adjusted the surgical gown. Summary of the Invention

[0005] To address these and other concerns, examples of the present disclosure provide surgical gowns and methods that allow for self-adjustment of the surgical gown without the wearer's hands leaving the area corresponding to the sterile zone.

[0006] Additionally, in another example, the surgical gown may include a zipper. However, including a zipper may cause the surgical gown to fail a microbial barrier test because the zipper may allow for the passage of fluids. To address this and other concerns, examples of the present disclosure provide a surgical gown that has a zipper or other closure mechanism and still provides the waterproof barrier necessary for the surgical gown to pass a microbial barrier test.

[0007] The self-adjusting surgical gown includes a front portion defining a centerline, a back portion, and two sides connecting the front and back portions. The self-adjusting surgical gown also includes a strap having a first end, a second end opposite the first end, and a connector portion. The strap is attached to the back portion at the first end. Further, the connector portion is removably coupled to a portion of the garment such that the second end is within an area corresponding to a sterile zone of a wearer. The area corresponding to a sterile zone of a wearer is defined, at least in part, as an area within 90 degrees on either side of the centerline.

[0008] A method of fastening a self-adjusting surgical gown is disclosed herein. The self-adjusting surgical gown comprises a front portion, a rear portion, two sides connecting the front portion and the rear portion, and first and second straps each having a first end, a second end opposite the first end, and a connecting portion. The first and second straps are each attached to the rear portion at the first end. The surgical gown also comprises a third strap removably connected to the first strap and the second strap. The method includes putting the self-adjusting surgical gown on a wearer such that the first and second straps are disposed at least partially outside an area corresponding to the wearer's sterile zone and the third strap is disposed at least partially within an area corresponding to the wearer's sterile zone. The method also includes moving the first and second straps from an initial state in which the connecting portions are connected to the rear or sides of the garment to a fastened state in which the connecting portions are connected to the front of the garment without the wearer's hands moving out of the area corresponding to the wearer's sterile zone.

[0009] The surgical gowns and methods disclosed herein allow a wearer to self-adjust and fasten straps on the surgical gown without removing both hands from the area corresponding to the wearer's sterile zone. This configuration helps prevent contamination from areas outside the area corresponding to the wearer's sterile zone from spreading to other locations in the operating room.

[0010] The surgical gown comprises a front portion, a rear portion defining a rear mid-line, and two side portions connecting the front and rear portions. The front portion, rear portion, and two side portions form a microbial barrier for a wearer. The surgical gown further comprises a closure mechanism disposed along the rear mid-line and a flap extending over the closure mechanism. The surgical gown also comprises at least one magnetic element adjacent the rear mid-line, the at least one magnetic element configured to secure the flap over the closure mechanism to provide a microbial barrier to the closure mechanism.

[0011] Also disclosed herein is a method of fastening a surgical gown comprising a front portion, a rear portion defining a rear midline, two side portions connecting the front and rear portions, a closure mechanism disposed along the rear midline, a flap extending over the closure mechanism, and at least one magnetic element adjacent the rear midline. The method includes the steps of: donning the surgical gown on a wearer, moving the closure mechanism such that the closure mechanism is in a closed position, and fastening the flap over the closure mechanism with the at least one magnetic element to provide a microbial barrier to the closure mechanism.

[0012] Advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings, in which: [Brief description of the drawings]

[0014] Referring to the drawings, in which like numbers are used throughout the several views to indicate like structures, a surgical gown is generally indicated at 20 in FIGS. 1-8. The surgical gown 20 is self-adjusting and configured to provide a barrier between the wearer and the outside environment. In one example, the surgical gown 20 is a toga configured to fall from the wearer's shoulders and cover past the wearer's knees. The toga may be an overhead toga such that the toga must be placed over the wearer's head in order to wear it. It is further contemplated that the toga may not require overhead wearing such that the toga includes a zipper or a set of ties to close the toga during use. The toga may also be paired with a surgical hood 22 to cover the head and neck area. The surgical hood or 22 may be a separate hood 22 such as that described in U.S. Patent Application No. 2016 / 066633, which is incorporated herein by reference. It is further contemplated that the surgical hood 22 may be integral with the toga or may be otherwise attached to the toga. In instances that include a hood or helmet 22, the term surgical attire 20 may refer to the toga itself or to the toga together with the surgical hood or helmet 22.

[0015] According to one embodiment, the surgical gown 20 may include a tightly woven fabric. The tightly woven fabric may be polyester, cotton, or a polyester-cotton blend. It is further contemplated that the surgical gown 20 may include nonwoven materials such as paper, cotton, polyester, and the like fibers or monofilaments. Alternatively, the surgical gown 20 may have coatings or other enhancements that provide additional barriers and / or are fluid impermeable. Typically, the surgical gown 20 is disposable such that the gown is disposed of as waste after only one use. However, it is contemplated that the surgical gown 20 may be a usable surgical gown 20 such that the gown is sterilized and reused for multiple uses.

[0016] 1-8, the surgical gown 20 comprises a front portion 24 defining a centerline 26, a rear portion 28, and two side portions 30, 32 connecting the front portion 24 and the rear portion 28. In the example shown in FIG. 2, when worn by a wearer, the front portion 24 of the surgical gown 20 covers the chest and abdominal areas of the wearer, while the rear portion 28 of the surgical gown 20 covers the rear and tail of the wearer. The first side portion 30 and the second side portion 32 respectively connect the front portion 24 of the surgical gown 20 to the rear portion 28 of the surgical gown 20 to provide a 360 degree barrier to the wearer.

[0017] In some examples, such as the example shown in FIG. 8, the rear portion 28 defines a rear midline 34 of the surgical gown 20. It is also contemplated that one or more of the first side portion 30 and the second side portion 32 may include a seam. In one example, the front portion 24 and the rear portion 28 of the surgical gown 20 may be manufactured in two separate pieces before being sewn together to form the surgical gown 20. In this example, the first and second side portions 30, 32 may each include a seam that extends longitudinally down the side of the surgical gown 20. In another example, the surgical gown 20 may be manufactured in a single flat piece that is secured to itself to form the surgical gown 20. In this example, only one of the first and second side portions 30, 32 includes a seam that extends longitudinally down the side of the surgical gown 20. It is further contemplated that the surgical gown 20 may be manufactured in a single piece such that no seam is required.

[0018] The surgical gown 20 may also include cuffs 36 at the ends of the sleeves to prevent contamination through the sleeves into the surgical gown 20. The cuffs 36 may be considered sterile, but the cuffs 36 may be covered by surgical gloves to completely seal off access into the surgical gown 20 from the arm area.

[0019] Establishing and maintaining a sterile field when performing surgery or other invasive procedures prevents microbial contamination that may pose an infection risk to the patient. Aseptic technique begins when a surgical team member enters the operating room and before the surgical attire is donned. Thus, the surgical team member donning and adjusting the surgical attire 20 should be careful to maintain a sterile zone in order to maintain a sterile field.

[0020] To this effect, as shown in FIG. 25, typically each surgical gown 20 may be contained in a sterile plastic package that remains sealed until the wearer opens the package in the operating room. The surgical gown 20 may be stored in the package in an upside-down orientation to allow the wearer to don the surgical gown 20 without compromising the sterility of the exterior of the surgical gown 20. Within the package, the surgical gown may be stored in a sterile plastic package that is sealed to a Sterility Assurance Level (SAL) of 10 or 12. -3 or a Sterility Assurance Level (SAL) of 10. -6 In the context of this disclosure, "SAL" refers to the probability that the surgical gown 20 is in a non-sterile state after it has undergone a sterilization process (and remains in the packaging free of further external contamination).

[0021] As used herein, the term "area corresponding to a sterile zone" 40 corresponds to the sterile zone in an operating room according to the Association of PeriOperative Registered Nurses (AORN) guidelines on aseptic technique. According to the AORN guidelines, when the surgical gown 20 is put on a wearer, the surgical gown 20 is considered sterile at the front 24 of the surgical gown 20 from the wearer's chest to the level of the sterile field. Typically, the level of the sterile field is at waist level because waist level is the limit of good visibility. However, it is also contemplated that the level of the sterile field may be at a level where a patient is placed, such as the height of an operating table. Also, according to the AORN guidelines, the shoulders, neckline, and axillary areas of the surgical gown 20 are considered non-sterile. Additionally, the rear 28 of the surgical gown 20 is considered non-sterile. Finally, the sleeves of the surgical gown 20 are considered sterile from about 2 inches above the elbow to the cuff of the surgical gown 20 around the arm.

[0022] The area 40 corresponding to the sterile zone is defined at least in part as the area within 90 degrees on either side of the centerline 26. Further, as best shown in FIG. 2 with respect to a three-dimensional Cartesian coordinate system, the area 40 corresponding to the sterile zone is defined as 90 degrees in the x-direction on either side from the intersection of the coronal and sagittal planes of the wearer adjacent the wearer's body. In FIG. 2, this intersection is labeled the wearer's longitudinal axis (LA). More specifically, the area 40 corresponding to the sterile zone can be represented by an angle α, which is bisected by the wearer's sagittal plane with the apex of the garment adjacent the front centerline 26. The angle α can range from 120 to 180 degrees, from 130 to 170 degrees, or from 140 to 160 degrees.

[0023] The area 40 corresponding to the sterile zone may also be defined in the y-direction from the wearer's chest to the wearer's waist in front of the wearer's coronal plane, and the area 40 corresponding to the sterile zone is defined in the z-direction from the front 24 of the surgical gown 20 to the length of the wearer's outstretched arms when the wearer's arms are parallel to the wearer's transverse plane in the x-direction within the area 40 corresponding to the sterile zone.

[0024] Referring now to the example shown in FIGS. 3-13, the surgical gown 20 also includes a strap 42 having a first end 44, a second end 46, and a connecting portion 48. As best shown in FIGS. 3A and 8, the first end 44 of the strap 42 is attached to the rear 28 of the surgical gown 20, and more specifically, is attached offset from the rear midline 34 of the rear 28 of the surgical gown 20. Typically, the first end 44 of the strap 42 is sewn or otherwise attached to the rear 28 of the surgical gown 20, although the first end 44 may be permanently attached in other manners. The stitching or other attachment mechanism should provide sufficient strength to allow for tightening of the strap without tearing or detaching. However, it is also contemplated that the first end 44 of the strap 42 may be attached to another portion of the rear 28 of the surgical gown 20 or to another location on the gown, including, but not limited to, another portion of the rear 28 of the surgical gown 20 or to a side of the gown 20. The second end 46 is opposite the first end 44 of the strap 42.

[0025] 3-13, the connecting portion 48 of the strap 42 is configured to be removably connected to a portion of the surgical gown 20. In one example, the connecting portion 48 is disposed on an inner surface 50 of the strap 42 such that the connecting portion 48 of the strap 42 can include a removably connecting device such as a hook and loop configuration, a snap fastening configuration, a button fastening configuration, or the like. According to one example, the connecting portion 48 of the strap 42 can include a hook configured to be removably connected to any portion of the surgical gown 20. Furthermore, the connecting portion 48 is configured to be detached from the gown and reconnected to another location. Also, in one example, when the surgical gown 20 is in a sterile package and before adjustment after donning the surgical gown 20, the connecting portion 48 can be removably connected to a portion of the gown such that the second end 46 is within the sterile zone 40 of the wearer.

[0026] In the example shown in FIGS. 3-13, strap 42 includes an outer surface 52 opposite an inner surface 50 that are joined together to form strap 42. As best shown in FIGS. 9-13, outer surface 52 is the side that faces outward when strap 42 is coupled to the garment at joint 48, and inner surface 50 is the side that includes joint 48 and is joined to surgical gown 20. However, it is contemplated that this configuration can be switched, or in one example, surgical gown 20 may include multiple straps 42, each strap 42 being of a different configuration. It is contemplated that strap 42 may also include additional fabric or cushioning between outer surface 52 and inner surface 50 for strength or comfort. In one example, strap 42 may include a nylon webbing material. However, it is contemplated that strap 42 may include cotton, plastic polymers, polyester, combinations thereof, and the like, without departing from the spirit of this disclosure. It is also contemplated that the straps 42 may further be constructed of a flexible or elastic material to allow for some stretching around the wearer during fastening.

[0027] Further, the thickness of the strap 42 can be about 5-15 millimeters (mm), with one example having a thickness of about 7-10 mm, and more specifically about 8 mm. However, it is contemplated that the thickness of the strap 42 can be any thickness to provide a desired level of strength and / or comfort to a user, for example. Also, the strap 42 can have a length sufficient to securely couple the strap 42 around a wearer of any size. For example, in one example, the length of the strap 42 can be about 25-150 centimeters (cm), with one embodiment having a length of about 50-100 cm, and more specifically about 80 cm. Further, the strap 42 can have a width sufficient to securely fasten the strap 42 and provide a desired strength. In one example, the width of the strap 42 can be about 20-80 mm, with one embodiment having a width of about 40-60 mm, and more specifically about 50 mm.

[0028] As shown in Figures 3-7, the strap 42 is configured to be moved between an initial state (see Figure 3) in which the connecting portion 48 is releasably connected to one of the side portions 30, 32 or the back of the surgical gown 20, and a fastened state (see Figure 7) in which the connecting portion 48 is releasably connected to the front portion 24 of the surgical gown 20. More specifically, in the initial state (Figure 3), the connecting portion 48 is releasably connected to a portion of the gown 20 such that the second end 46 of the strap 42 is within the region 40 corresponding to the sterile zone of the wearer. It is contemplated that the second end 46 can be disposed partially or completely within the region 40 corresponding to the sterile zone of the wearer. For example, the second end 46 of the strap 42 can be disposed at least partially within the region 40 corresponding to the sterile zone of the wearer such that the wearer can engage the second end 46 of the strap 42 without having to move both hands from the region 40 corresponding to the sterile zone. Additionally, when the strap 42 is moved to the fastened state (FIG. 7), the second end 46 is moved toward the centerline 26 of the surgical gown 20 such that the second end 46 is disposed at least partially, and typically completely, within the region 40 corresponding to the wearer's sterile zone.

[0029] The fastening state (FIG. 7) can be any state closer to the centerline 26 than the initial state (FIG. 3). The fastening state (FIG. 7) can be slightly different for each wearer depending on the size and shape of the wearer's body. For example, the fastening state (FIG. 7) for a smaller than average size wearer requires a larger distance between the initial state (FIG. 3) and the fastening state (FIG. 7) than the fastening state (FIG. 7) for a larger than average size wearer. In other words, the fastening state (FIG. 7) can be adjusted within the region 40 corresponding to the wearer's sterile zone to secure the gown 20 for any size wearer. It is contemplated that the straps 42 may cross the centerline 26 of the surgical gown 20 for fastening, if necessary. In other words, in the fastening state (FIG. 7), the second ends 46 of the straps 42 can be anywhere within the region 40 corresponding to the wearer's sterile zone, such that the wearer does not need to go outside the region 40 corresponding to the sterile zone to fully fasten the surgical gown 20.

[0030] As shown in FIGS. 3-13, the strap 42 can include a first segment 70 and a second segment 72. In one example, the second segment 72 defines the second end 46, and the second segment 72 can be separable from the first segment 70. Also, in the initial state (FIG. 3), the first segment 70 of the strap 42 can be disposed at least partially outside the region 40 corresponding to the sterile zone of the wearer, and the second segment 72 of the strap 42 can be disposed at least partially within the region 40 corresponding to the sterile zone of the wearer. As best shown in FIGS. 9-13, the first segment 70 and the second segment 72 can include corresponding fastening portions 74 that removably couple the first segment 70 and the second segment 72. Also, the first segment 70 can include fastening portions 74 that are disposed on the outer surface 52 of the strap 42 such that the fastening portions 74 face away from the surgical gown 20 when the strap 42 is in the initial state (FIG. 3). The corresponding fastening portion 74 is disposed on the inner surface 50 of the second segment 72 of the strap 42 such that the fastening portion 74B of the second segment 72 faces toward the surgical gown 20 when the strap 42 is in the initial state (FIG. 3).

[0031] 3-13, as discussed above, the first segment 70 of the strap 42 may include the portion of the strap 42 that is fixedly coupled to the surgical gown 20. The second segment 72 of the strap 42 has a first end section 76 that is removably coupled to the first segment 70 and has an opposing end section 78 that defines the second end 46 of the strap 42. Additionally, in some configurations, the first segment 70 and the second segment 72 overlap at least at the corresponding fastening portion 74. It is also contemplated that the first and second segments 70, 72 may overlap over a length that does not include the corresponding fastening portion 74. In other words, it is contemplated that the fastening portion 74 on the strap 42 may be disposed anywhere on the first segment 70 such that the second segment 72 may overlap the first segment 70 along some or all of the length of the first segment 70. Additionally, it is contemplated that the first segment 70 may include a plurality of fastening portions 74 and the second segment 72 may also include a plurality of corresponding fastening portions 74. In one example, the corresponding fastening portions 74 are corresponding hook and loop fasteners. However, it is contemplated that the corresponding fastening portions 74 may be snap fasteners, button fasteners, and the like without departing from the spirit of the present disclosure. Additionally, it is contemplated that the first and second segments 70, 72 may be separated from one another by a perforated joint rather than using separate fasteners.

[0032] In one example, the corresponding fastenings 74 are of a type that remain fixed when the wearer pulls on the second segment 72 to move the straps 42 from an initial state (FIG. 3) to a tightened state (FIG. 7), but can be easily detached from the first segment 70 when pulled in the opposite direction. Thus, the second segment 72 remains connected to the first segment 70 during tightening of the straps 42 of the surgical gown 20, but can be easily released by the wearer when desired. In one illustrative example, directional micro hook and loop fasteners are used, although various other attachment configurations are contemplated.

[0033] As best shown in FIG. 3A, the second segment 72 may also include an additional connector 49 disposed on the second end 46 of the strap 42. The additional connector 49 may be configured to secure the second end 46 of the strap 42 to the surgical gown 20 to ensure that the second end 46 of the strap 42 remains within the area 40 corresponding to the sterile zone when the strap 42 is in the initial state (FIG. 3). In other words, the additional connector 49 is removably coupled to the front portion 24 of the surgical gown 20 when the strap 42 is in the initial state (FIG. 3), which allows the wearer to grasp the second end 46 of the strap 42 and move the strap 42 to the fastened state (FIG. 7) without removing both hands from the area 40 corresponding to the sterile zone.

[0034] In one example, the surgical gown 20 may include an identical strap (not shown) attached to the surgical gown 20 on either side of the back midline 36 from the strap 42 described above. Typically, the additional strap includes the same features as the original strap 42, including the first segment 70, the second segment 72, the end portion 46, and the connection portion 48. The identical strap 42 may also be configured to be moved from an initial state to a fastened state by the wearer without removing both hands of the wearer from the area 40 corresponding to the sterile zone, as described above.

[0035] With further reference to Figures 3 to 13, as explained in more detail above, during surgery, the surgical gown 20 starts in an upside-down orientation in a sterile packaging and with the straps 42 in an initial state (Figure 3), i.e. with the second ends 46 located in the area 40 corresponding to the wearer's sterile zone. The wearer can then open the sterile packaging and put on the surgical gown 20 without touching the outside of the gown 20. Once the surgical gown 20 is put on by the wearer, the wearer can tighten the straps 42 of the surgical gown 20 around himself. To do so, the wearer can engage the second ends 46 of the straps 42, which are located in the area 40 corresponding to the wearer's sterile zone, and can decouple the couplings 48 and 49 from the surgical gown. The wearer can then move the straps 42 to the tightened state (Figure 7) and reconnect the couplings 48 to the surgical gown 20. Once straps 42 are moved to the fastened state (FIG. 7), second segments 72 of straps 42, if included, are decoupled from first segments 70 of straps 42 and can then be disposed of. By using this configuration of surgical gown 20 in conjunction with the disclosed method of adjusting surgical gown 20, the wearer can adjust surgical gown 20 without the assistance of an additional person and without the wearer's hands leaving area 40 corresponding to the sterile zone, as compared to conventional approaches in which assistance is required.

[0036] In another example shown in FIGS. 14-24, the strap 79 includes a first strap 80 and a second strap 82, each including a first end 44, a second end 46 disposed opposite the first end 44, and a coupling portion 48. Additionally, the strap 79 can include a third strap 84 removably coupled to both the first and second straps 80, 82. In some embodiments, the third strap 84 can be substantially similar to the second segment 72 described above with reference to FIGS. 4-13. More specifically, the third strap 84 includes a fastening portion 74 for removably coupling to the fastening portion 74 of the second ends 46 of the first strap 80 and the second strap 82. As best shown in FIG. 19, the first and second straps 80, 82 are each attached to the rear portion 28 at the first end 44. More specifically, the first and second straps 80, 82 are disposed on either side of the back midline 34 of the rear portion 28 of the surgical gown 20. It is also contemplated that the first and second straps 80, 82 may be attached to other locations on the rear portion 28 of the surgical gown 20.

[0037] 14-24, as previously described, when the surgical gown 20 is in the sterile packaging, the first and second straps 80, 82 may be disposed at least partially outside the area corresponding to the wearer's sterile zone 40, and the third strap 84 may be disposed at least partially within the area corresponding to the wearer's sterile zone 40. In other words, in the initial state of the first and second straps 80, 82 (FIG. 14), at least a portion of the first and second straps 80, 82 are disposed outside the area corresponding to the wearer's sterile zone 40, and the third strap 84 is disposed at least partially within the area corresponding to the wearer's sterile zone 40. In one example, as shown in FIG. 14, the second ends 46 of the first and second straps 80, 82 may be disposed on the side portions 30, 32 or back portion 28 of the surgical gown 20 such that the entire first and second straps 80, 82 are disposed outside the area corresponding to the sterile zone 40. Additionally, the first and second straps 80, 82 are configured to be moved between an initial condition (FIG. 14) and a fastened condition (FIG. 18) in which the connector 48 is releasably coupled to the front portion 24 of the surgical gown 20. Additionally, when the surgical gown 20 is in the sterile packaging, the configuration of the surgical gown 20 is typically inverted as described above.

[0038] As shown in the examples shown in Figs. 14-24, the third strap 84 can connect the second ends 46 of the first and second straps 80, 82 such that the third strap 84 is disposed between the first strap 80 and the second strap 82. Also, the third strap 84 may be of any length, preferably long enough to encircle the body of a wearer of any size, but not too long so that the third strap 84 extends outside the area 40 corresponding to the sterile zone in the initial state (Fig. 14). More specifically, as described above, in the initial state (Fig. 14), as shown in Fig. 14, the first and second straps 80, 82 are at least partially disposed outside the area 40 corresponding to the sterile zone of the wearer, and the third strap 84 connected between the first and second straps 80, 82 is at least partially disposed within the area corresponding to the sterile zone 40.

[0039] The third strap 84 allows the user to engage the portion of the third strap 84 located within the area 40 corresponding to the sterile zone and pull the first, second and third straps 80, 82, 84 forward within the area 40 corresponding to the sterile zone until the desired tightness of the surgical gown 20 is reached. The action of pulling the third strap 84 decouples the coupling portions 48 of the first and second straps 80, 82 from an initial state (see FIG. 14) and allows the straps to move to a tightened state (FIG. 18). Once the desired tightness is reached, the user allows the coupling portions 48 of the first and second straps 80, 82 to reconnect with the surgical gown 20 within the area 40 corresponding to the sterile zone in the tightened state (FIG. 18). Once the first and second straps 80, 82 are in the tightened state (FIG. 18), the third strap 84 may be detached from the first and second straps 80, 82.

[0040] As mentioned above, the third strap 84 includes a fastening portion 74 adjacent each end thereof for releasably connecting the third strap 84 to the first and second straps 80, 82. Once the first and second straps 80, 82 are in the fastened state (FIG. 18), the wearer can uncouple each fastening portion 74 of the third strap 84 from the first and second straps 80, 82. In one example, the fastening portions 74 of the third strap 84 are of a type that remain fastened when the wearer pulls the third strap 84 to move the first and second straps 80, 82 from the initial state (FIG. 14) to the fastened state (FIG. 18), but can be easily removed from the first and second straps 80, 82 when pulled in the opposite direction. Thus, the third strap 84 remains connected to the first and second straps 80, 82 during fastening of the surgical gown 20, but can be easily released by the wearer when desired. In one example, directional micro hook and loop fasteners are used, although a variety of other fastening configurations are contemplated.

[0041] It is contemplated that the first and second straps 80, 82 may include the same or similar features and orientations as the trap 42, including, but not limited to, the first end 44, the second end 46, the inner surface 50, the outer surface 52, the thickness, the length, the width, the bond portion 48, and the fastening portion 74. It is also contemplated that the first and second straps 80, 82 may be identical or similar to one another. However, it is also contemplated that the first and second straps 80, 82 may have any of the alternative features and / or configurations as described above with respect to the strap 42. It is also contemplated that each of the first and second straps 80, 82 may differ from one another without departing from the spirit of the present disclosure.

[0042] With further reference to the example shown in Figures 14-24, during surgery, the surgical gown 20 begins in a sterile packaging in an upside-down orientation with the first and second straps 80, 82 in their initial state (Figure 14). The wearer can then open the sterile packaging and don the surgical gown 20 without touching the outside of the gown 20. Once the surgical gown 20 is donned by the wearer, the wearer can tighten the surgical gown 20 around himself. To do so, the wearer can engage the third strap 84 located within the area 40 corresponding to the sterile zone and pull the third strap 84 forward to tighten the first and second straps 80, 82 without having to move his hands out of the area corresponding to the sterile zone. When the first and second straps 80, 82 are transferred to the fastened state (FIG. 18), the wearer can cease pulling on the third strap 84, thereby allowing the first and second straps 80, 82 to re-engage with the surgical gown 20 in the fastened state (FIG. 18). The wearer can then disconnect the third strap 84 from the first and second straps 80, 82 and dispose of the third strap 84. In the fastened state (FIG. 18), the second ends 46 of the first and second straps 80, 82 are disposed within the area 40 corresponding to the wearer's sterile zone such that the wearer can disconnect the third strap 84 without removing both of the wearer's hands from the area 40 corresponding to the sterile zone. Also, by using this configuration of the surgical gown 20 together with the disclosed method of adjusting the surgical gown 20, the wearer can adjust the surgical gown 20 without the assistance of an additional person and without the wearer's hands being removed from the area 40 corresponding to the sterile zone.

[0043] 26 and 27, a surgical gown 190 is disclosed. The surgical gown 190 shown in FIG. 26 and FIG. 27 can include any or all of the features described above with reference to the surgical gown 190 shown in FIG. 1-25 and described herein, including, but not limited to, the straps 42 and / or the connectors 48. In the example shown in FIG. 26 and FIG. 27, the surgical gown 190 includes a front portion 124, a rear portion 128 defining a back midline 134, and two side portions 130, 132 connecting the front portion 124 and the rear portion 128. The front portion 124, the rear portion 128, and the two side portions 130, 132 form a microbial barrier for the wearer. The surgical gown 190 also includes a closure mechanism 192 disposed therethrough to allow the surgical gown 190 to be opened to facilitate donning. More specifically, the closure mechanism 192 is configured to be moved between an open position in which the rear 128 of the surgical gown 190 is open and a closed position in which the rear 128 of the surgical gown 190 is closed. The closure mechanism 192 may be disposed along the rear midline 134 or may be disposed off-center of the rear midline 134 such that the closure mechanism 192 may be disposed elsewhere on the rear 128 of the surgical gown 190. It is also contemplated that the closure mechanism 192 may be disposed on the front 124 of the surgical gown 190, if desired. In one example shown in FIG. 26, the closure mechanism 192 is a zipper. More specifically, in the example shown in FIG. 6, the zipper is a waterproof zipper, such as a reverse coil zipper. However, it is also contemplated that the closure mechanism 192 may comprise any other mechanism configured to close the garment, including, but not limited to, any type of zipper, clasp, button, hook and loop, and other fasteners.

[0044] 26 and 27, the surgical gown 190 also includes a flap 194 that extends over the closure mechanism 192. The flap 194 may be constructed of the same material as the rest of the surgical gown 190, such as a tightly woven fabric as described above. It is also contemplated that the flap 194 may include an additional waterproof barrier or coating and / or may be made of a different material configured to provide a microbial barrier to the wearer. It is also contemplated that the flap 194 may have a thickness similar to that of the rest of the surgical gown 190. However, it is also contemplated that the flap 194 may have a greater or lesser thickness that provides an additional liquid barrier.

[0045] In the example shown in FIGS. 26 and 27, the flap 194 is generally rectangular and has a length equal to the length of the surgical gown such that the flap 194 is configured to extend the entire length of the closure mechanism 192. It is also contemplated that the flap 194 may have a shorter length so that a portion of the closure mechanism 192 may be exposed outside the surgical gown 190 below the sterile zone, if desired. The flap 194 also has a width that is at least as wide as the closure mechanism 192. In the example shown in FIGS. 26 and 27, the flap 194 includes a first edge 196 and a second edge 198. The first edge 196 is secured to the back 128 of the gown adjacent the closure mechanism 192. The first edge 196 may be secured to the surgical gown by any method, including but not limited to, suturing or gluing. The second edge 198 is configured to extend opposite the closure feature 192 such that the flap 194 extends across the closure feature 192. Further, it is contemplated that the flap 194 may have a consistent thickness, length, and / or width, or, alternatively, one or more of the thickness, length, or width of the flap 194 may be varied, as desired.

[0046] With further reference to the example shown in FIG. 26 and FIG. 27, the surgical gown 190 also includes at least one magnetic element 200 adjacent the back midline 134 and configured to secure the flap 194 over the closure mechanism 192 to provide a microbial barrier to the closure mechanism 192. In one example, the magnetic element 200 is a permanent magnet configured to generate a magnetic field. Also, as best shown in FIG. 26, the at least one magnetic element 200 may be a first magnetic element sealed within the flap 194. In the example shown in FIG. 26, five magnetic elements 200 are sealed within the flap 194. However, six or more or four or less magnetic elements 200 may be sealed within the flap 194. The magnetic element 200 may be centrally sealed within the flap 194 relative to the width of the flap 194, or may be disposed closer to the first edge 196 or the second edge 198. Also, the magnetic elements 200 may be evenly distributed along the length of the flap 194 or may be clustered in one or more portions along the flap 194. It is contemplated that the magnetic elements 200 are not sealed within the flap 194 but are otherwise attached to the flap 194, for example, by adhesive, and further configured to secure the flap 194 over the closure mechanism 192.

[0047] Additionally, the at least one magnetic element 200 may be a second magnetic element sealed within the rear portion 128 of the surgical gown 190. The second magnetic elements 201 are disposed adjacent to the closure mechanism 192 on either side of the closure mechanism 192 from the first edge 196 of the flap 194. In the example shown in FIG. 26, five second magnetic elements 201 are sealed within the rear portion 128. However, six or more or four or less second magnetic elements 201 may be sealed within the rear portion 128. It is also contemplated that the second magnetic elements 201 are not sealed within the rear portion 128 but may be attached to the rear portion 128 in other ways, for example, by gluing. Additionally, the second magnetic element 201 coupled to the rear portion 128 of the surgical gown 190 is configured to couple with the first magnetic element 200 coupled to the flap 194 of the surgical gown 190 such that the first magnetic element 200 coupled to the flap 194 of the surgical gown 190 and the second magnetic element 201 coupled to the rear portion 128 of the surgical gown 190 have opposite polarities. Additionally, one of the magnetic elements 200 in the flap 194 is configured to couple with one of the second magnetic elements 201 in the rear portion 128 such that the rear portion 128 and the flap 194 each contain the same number of magnetic elements 200.

[0048] In another example, the surgical gown 190 comprises a ferrous element 202 configured to be coupled to at least one magnetic element 200 to secure the flap 194 over the closure mechanism 192 to provide a microbial barrier to the closure mechanism 192. In one example, the ferrous element 202 replaces the magnetic element 200 in the rear 128 of the surgical gown 190 such that the ferrous element 202 is sealed within or otherwise attached to the rear 128 of the surgical gown 190. In this example, the ferrous element 202 in the rear 128 of the surgical gown 190 is configured to be coupled to the magnetic element 200 in the flap 194 to secure the flap 194 over the closure mechanism 192 to provide a microbial barrier to the closure mechanism 192. In yet another example, the ferrous element 202 replaces the magnetic element 200 in the flap 194 of the surgical gown 190 such that the ferrous element 202 is sealed within or otherwise attached, for example, by adhesion, to the flap 194 of the surgical gown 190. In this example, ferrous elements 202 in the flap 194 of the surgical gown 190 are configured to couple to magnetic elements 200 in the back portion 128 of the surgical gown 190 to secure the flap 194 over the closure mechanism 192 to provide a microbial barrier to the closure mechanism 192. The ferrous elements 202 can be similar to the magnetic elements 200 as described above with respect to their placement and number within the flap 194 or back portion 128. For example, one of the magnetic elements 200 is configured to couple to one of the ferrous elements 202 such that the back portion 128 and the flap 194 include the same number of magnetic elements 200 and ferrous elements 202.

[0049] With further reference to the examples shown in Figs. 26 and 27, during surgery, first, the wearer puts on the surgical gown 190. Then, the closure mechanism 192 is moved so that the closure mechanism 192 is in the closed position (Fig. 26). Finally, as shown in Fig. 27, the flap 194 is secured onto the closure mechanism 192 using the magnetic element 200 to provide a microbial barrier to the closure mechanism 192. More specifically, the flap 194 is secured onto the closure mechanism 192 by coupling the magnetic element 200 or ferrous element 202 located within the flap 194 with the magnetic element 200 or ferrous element 202 located within the rear portion 128 of the surgical gown 190. When the flap 194 is secured onto the closure mechanism 192, the flap 194 provides the closure mechanism 192 with a microbial barrier that prevents liquid from entering the surgical gown 190 through the closure mechanism 192.

[0050] Also, while the protective clothing system is generally intended to provide a barrier between a physician and a patient during a medical procedure or surgery, its use is not limited thereto. It is within the scope of this disclosure that the garment may be used in other endeavors in which it is desirable to provide a barrier between an individual and the surrounding environment. One alternative endeavor in which it may be desirable to use the garment is one in which it is desirable to provide a barrier between an individual and hazardous materials within the environment in which the individual is working.

[0051] A number of examples have been set forth in the foregoing description. However, the examples set forth herein are not intended to be exhaustive or to limit the invention to any particular form. The terminology used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations are possible in light of the above teachings, and the invention may be practiced otherwise than as specifically described.
