This disclosure relates generally to infection control products, and more specifically, to a disposable contact isolation gown that is generally utilized by healthcare workers and visitors to certain hospital units.
Utilizing disposable isolation contact gowns (also referred to as contact precautions gowns) is standard practice among healthcare workers when interacting with patients placed under isolation precautions. Isolation contact gowns are meant to protect healthcare workers from hospital-acquired infections (e.g., Clostridium difficile) when interacting with patients. For an isolation contact gown to be an effective barrier against sources of infectious agents (e.g., blood, bodily fluids, secretions), the gown needs to fully cover a wearer's body. For example, when a gown is left untied, and a portion of the wearer's clothing or skin is exposed, there is a chance that bacteria or viruses may come in contact with the wearer as the wearer engages in patient-care activities. The wearer subsequently risks exposing other people to infection as the wearer comes in contact with other healthcare workers and patients.
Gowns that fully surround the body are the norm for certain patients, due to prior clothing removal. However, with a heightened awareness regarding infection prevention and control in the healthcare setting, there is a corresponding need for healthcare workers, and any visitors to certain units within a medical facility, to be completely covered when interacting with patients. A full coverage gown that can easily be put on by a user, and easily taken off by the user is more likely to be worn properly by a user, and protect the user against infection and contamination. As such, there is still an unfilled need for a full coverage gown that requires minimal effort to wear properly and remove efficiently.
In one embodiment, a disposable contact isolation gown for protection from hospital-acquired infections is provided. The contact isolation gown includes a front panel including a front collar edge, a pair of front shoulder edges, a pair of front side edges, and a front bottom edge. The gown also includes a back panel coupled to the front panel at a pair of side seams. The back panel includes a back collar edge, a back line of weakness extending from the back collar edge to the back bottom edge, and a pair of back panel portions coupled together at the back line of weakness. The gown also includes a pair of arm panels coupled between the front panel and the back panel. Each arm panel includes an arm panel back edge, an arm panel front edge, and an arm panel collar edge.
In another embodiment, a disposable contact isolation gown is provided that includes a front panel, a back panel, and a pair of arm panels. The isolation contact gown includes a front panel that has a front collar edge, a pair of front shoulder edges, a pair of front side edges, and a front bottom edge. The isolation contact gown also includes a back panel coupled to the front panel at a pair of side seams. The back panel includes a back collar edge, a pair of back shoulder edges extending from the back collar edge, a back line of weakness extending from the back collar edge, a pair of back side edges, and a back bottom edge. The isolation contact gown also includes a pair of arm panels coupled between the front panel and the back panel. Each arm panel includes an arm panel back edge, an arm panel front edge, an arm panel collar edge, a sleeve back edge, a sleeve front edge, and a cuff edge. The arm panel back edge of each arm panel is coupled to one of the back shoulder edges at a shoulder line of weakness.
In yet another embodiment, a method of manufacturing a disposable contact isolation gown is provided. The method includes providing a front panel comprising a front collar edge, a pair of front shoulder edges, a pair of front side edges, and a front bottom edge. The method also includes providing a back panel coupled to the front panel at a pair of side seams. The back panel includes a back collar edge, a back line of weakness extending from the back collar edge to the back bottom edge, and a pair of back panel portions coupled together at the back line of weakness. The method also includes providing a pair of arm panels coupled between the front panel and the back panel. Each arm panel includes an arm panel back edge, an arm panel front edge, and an arm panel collar edge.
The following detailed description illustrates the disclosure by way of example and not by way of limitation. The description enables one skilled in the art to make and use the disclosure, describes several embodiments, adaptations, variations, alternatives, and uses of the disclosure, including what is presently believed to be the best mode of carrying out the disclosure.
Embodiments of the present disclosure provide a disposable contact isolation gown including a front panel, a back panel, and a pair of arm panels coupled between the front panel and the back panel. Embodiments include a back panel coupled to a pair of arm panels at a shoulder line of weakness of a front collar edge. Embodiments also include a back line of weakness extending from the back collar edge. Some embodiments include a front collar edge that is un-removably attached to the arm panel collar edges of the arm panel. Embodiments of the present disclosure also include a back collar edge that is detachably coupled to the arm panel collar edges of the arm panels. The back collar edge includes a line of weakness that extends the length of back collar edge. The front collar edge, arm panel collar edges, and the back collar edge form a head opening. The head opening enables a wearer to easily wear the gown by inserting their head through the head opening. Embodiments of the present disclosure also include fully formed sleeves for the wearer to insert their respective arms through. When properly worn, the shoulders, arms, torso and a portion of the wearer's legs are covered and protected by the gown.
Embodiments also include the back line of weakness extending from the back collar edge to a back bottom edge. Some embodiments include a pair of back panel portions coupled together at a back line of weakness. Additionally, embodiments of the present disclosure include a pair of back shoulder edges extending from the back collar edge. Each back shoulder edge forms a portion of a shoulder line of weakness. The shoulder lines of weakness, the back line of weakness, and the lines of weakness proximate the back collar edge, are all useful in enabling a wearer to remove the gown. When a wearer wants to remove the gown, the wearer grabs a portion of the front panel and pulls the front panel away from their body. The lines of weakness described above will cause breakages, allowing for a relatively easy removal of the gown. The lines of weakness may be manufactured to vary in strength to enable different areas of the gown to tear first (e.g., back shoulder edges, back collar edge, back panel). In other embodiments, the lines of weakness may be manufactured to be substantially equal in strength to enable the shoulder lines of weakness, the back line of weakness, and the lines of weakness proximate the back collar edge to tear at the same time.
As used herein, “line of weakness” refers to perforations (e.g., serrations), and is illustrated in the figures as dash-dot lines. Lines of weakness allow for quick and easy removal of the gown when the wearer pulls on a portion of the front panel, such as the front collar edge. As mentioned above, lines of weakness are shown in the figures as dash-dot lines in the material from which the gown is fabricated. In alternative embodiments, lines of weakness can take the form of individual ovals or other geometric figures that have been cut out of the material, simplifying removal of the gown from the wearer.
Embodiments of the present disclosure include tie members to enable the wearer to secure the gown around the wearer's body. A pair of tie members can be affixed to the front panel and/or the back panel. Tie members can be provided on opposing sides of the front panel and/or the back panel. The wearer can couple the front panel tie members with the back panel tie members at corresponding sides of the wearer's body. The tie members allow the wearer to adjust the size and shape of the gown so the gown can fully and securely cover the wearer.
In some embodiments, the tie members on the front and/or back panels can be encased or covered in a plastic film. The plastic film includes a pull tab feature that enables the wearer to peel the plastic film to access the tie member. The plastic film helps to keep the tie members secure to the gown to avoid the tie members from being snagged when not being used with the gown. In these embodiments, the wearer is provided with the option of having tie members if the wearer needs a more secure fit. In certain embodiments, the tie members may be of flexible retractable material that allow the tie members to stretch and return to their respective side edge positions. For example, in these embodiments, the tie members may be spring-loaded (e.g., spring-based) and/or coil-shaped tie members that stretch in an accordion-like manner and retract to a compact configuration to avoid being snagged or caught on something, such as a medical equipment, when not tied. In further embodiments, the disposable contact isolation gown may not include tie members. In these embodiments, elastic gatherings may be provided on the front panel and/or the back panel so the gown can securely fit the wearer without a tie member. In these embodiments, elastic may be provided part of the gown material, and may enable the front panel and/or the back panel to stretch and contract based upon the size of the wearer to ensure a snug fit for the wearer.
Embodiments of the disposable contact isolation gown may be fabricated using nonwoven fabric. Nonwoven fiber-bonding technologies (e.g., thermal, chemical, or mechanical) may be used to produce embodiments of the gown. Additionally, the gown may be fabricated from suitable forms of synthetic fibers (e.g., polypropylene, polyester, polyethylene). One embodiment of the gown is fabricated using polypropylene that has been coated with a polyethylene coating. Another embodiment utilizes spunbond meltblown spunbond (SMS) materials in the fabrication of the gown. Another embodiment of the gown is fabricated using low-density polyethelene (LDPE).
Upon completion of manufacturing, the disposable contact isolation gown is folded and placed into a fold-over, self-contained pouch which is sized to be compatible with at least one known personal protection equipment organizer. In embodiments where the disposable contact isolation gown does not include tie members, a belt can separately be provided in the self-contained pouch. In these embodiments, the belt may be used to provide wearers, such as those with small frames, a more secure fit. The gown may be manufactured in a single size (e.g., one size). In an alternative embodiment, the gown may be manufactured in a variety of sizes (e.g., small, medium, large, x-large, xx-large).
Referring now to the drawings,
Back panel 104 includes a back line of weakness 122 that extends from a back collar edge 126. In the example embodiment, back line of weakness 122 includes a plurality of lines of weakness oriented parallel relative to each other. Back line of weakness 122 extends from a back collar edge 126 to a back bottom edge 124. In the example embodiment, back panel 104 also includes a pair of back panel portions, such as a first back panel portion 118 and a second back panel portion 120, which are coupled together at back line of weakness 122. Back line of weakness 122 may be substantially equal to a length of the pair of back panel portions (first back panel portion 118 and second back panel portion 120).
Back collar edge 126 also includes a line of weakness along the length of back collar edge 126. In the example embodiment, the line of weakness extends along the entire length of back collar edge 126. In some embodiments, a line of weakness extends along a partial length of back collar edge 126. In other embodiments, back collar edge 126 includes a plurality of lines of weakness. Back collar edge 126 is between a pair of back shoulder edges, such as first back shoulder edge 128 and a second back shoulder edge 130. Back panel 104 also includes a pair of back side edges, such as first back side edge 170 and second back side edge 172. First back side edge 170 is attached to first back shoulder edge 128, and second back side edge 172 is attached to second back shoulder edge 130. First back shoulder edge 128 and second back shoulder edge 130 extend obliquely from back collar edge 126. Each back shoulder edge 128 and 130 forms a portion of a shoulder line of weakness, as shown by dash-dot lines along back shoulder edges 128 and 130. Other configurations for lines of weakness are considered, as long as they provide the utility of tearing the material of gown 100 in the location of the line of weakness when the wearer pulls a portion of front panel 102 away from their body.
First arm panel 108 and second arm panel 110 are positioned between front panel 102 and back panel 104. First arm panel 108 includes a first arm panel collar edge 132 between a first arm panel front edge 134 and a first arm panel back edge 136. First arm panel 108 also includes a first sleeve back edge 174 attached to first arm panel back edge 136, and a first sleeve front edge 176 attached to first arm panel front edge 134. First arm panel back edge 136 forms a portion of a shoulder line of weakness, as shown by dash-dot lines along first arm panel back edge 136. A first sleeve 138 extends between first arm panel collar edge 132 and a first cuff edge 158. Second arm panel 110 includes a second arm panel collar edge 140 between a second arm panel front edge 142 and a second arm panel back edge 144. Second arm panel 110 also includes a second sleeve back edge 178 attached to second arm panel back edge 144, and a second sleeve front edge 180 attached to second arm panel front edge 142. Second arm panel back edge 144 forms a portion of a shoulder line of weakness, as shown by dash-dot lines along second arm panel back edge 144.
A second sleeve 146 extends between second arm panel collar edge 140 and a second cuff edge 148. In the example embodiment, first cuff edge 158 and second cuff edge 148 include elastic gatherings to provide a secure fit. The elastic gatherings may be one or more elastic bands, strips, or fold-over elastic material. When properly utilized, the elastic gatherings of first cuff edge 158 and second cuff edge 148 provide a gathering function for excess sleeve material, which is beneficial to wearers of different sizes. Further, the elastic gatherings of first cuff edge 158 and second cuff edge 148 prevent the sleeves, first sleeve 138 and second sleeve 146, from creeping up the arm or getting in the way of the wearer during use of gown 100. Similarly, front collar edge 112, first arm panel collar edge 132, and second arm panel collar edge 140 also include elastic gatherings (e.g., elastic/rubber bands) to provide a secure fit around the wearer's neck. The elastic gatherings of the sleeves (first sleeve 138 and second sleeve 146) and the collar edges (front collar edge 112, first arm panel collar edge 132, and second arm panel collar edge 140) allow for the arm sleeves and collar to expand and contract to accommodate different body sizes (e.g., differences in arm and neck circumferences). Such features not only operate to make gown 100 more pleasant to wear, but help reduce the spread of germs, viruses, bodily fluids, and the like.
Gown 100 includes tie members 160, 162, 182, and 184 to allow for size adjustments. In the example embodiment, front panel 102 includes first front tie member 160 proximate first front side edge 164, and a second front tie member 162 proximate second front side edge 166. Back panel 104 includes a first back tie member 182 proximate first back side edge 170, and a second back tie member 184 proximate second back side edge 172. In the example embodiment, the wearer ties first front tie member 160 and first back tie member 182 together, and second front tie member 162 and second back tie member 184 together.
In the example embodiment, tie members are positioned at opposing side edges of front panel 102 and back panel 104. Tie members may be attached to front panel 102 and back panel 104 by utilizing any suitable fastening means that do not cut into gown 100, as cuts (e.g., slits, holes, openings) in gown 100 may expose the wearer's skin and/or clothes to contaminants. Suitable fastening means may include stitches, adhesives, and/or other sealing processes such as a heat seal.
In one embodiment, ends 152 and 154 of first front tie member 160 and second front tie member 162 may be sewn to front panel 102. Similarly, ends 186 and 188 of first back tie member 182 and second back tie member 184 may be sewn to back panel 104. In another embodiment, a heat seal may be used to attach ends 152 and 154 to front panel 102 and ends 186 and 188 to back panel 104. Tie members are of a length that will accommodate most, if not all, wearers of gown 100.
First arm panel back edge 136 is coupled to first back shoulder edge 128 (both shown in
Front collar edge 112 is non-removably attached to first arm panel collar edge 132 and second arm panel collar edge 140. In one embodiment, front collar edge 112, first arm panel collar edge 132, and second arm panel collar edge 140 are unitarily formed. In the example embodiment, front collar edge 112, first arm panel collar edge 132, and second arm panel collar edge 140 include elastic gatherings (e.g., elastic bands, elastic straps) to provide a secure fit around the wearer's neck. Back collar edge 126 is detachably coupled to first arm panel collar edge 132 and second arm panel collar edge 140. As explained in
As explained in
Although the terms first and second may be used herein to describe various elements, components, and/or sections, these elements, components, and/or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, or section from another element, component, or section. Terms such as “first” and “second” when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, or section discussed below could be termed a second element, component, or section without departing from the teachings of the example embodiments.
In the example embodiment, tie members 160 and 162 retain a relatively compressed shape in the closed configuration as they are enclosed in a protective covering 308. In the open configuration, tie members 160 and 162 are released from protective covering 308, and are similar to or the same as the disposition of tie members 160 and 162 as shown in
In the example embodiment, the protective covering 308 (e.g., protective film) may be a plastic film (e.g., peel-off film), adhesive, and/or any suitable material that can fully cover tie members 160 and 162. Protective covering 308 prevents unused tie members from potentially interfering with the wearer's activities and inconveniencing the wearer by allowing the unused tie members to be tucked away. Protective covering 308 includes a pull tab 306 that enables the wearer to remove protective covering 308 to access an enclosed tie member. The wearer may subsequently extend the enclosed tie member from a closed (e.g., compressed) configuration to an open configuration. In the example embodiment, the wearer extends tie members 160 and 162 into an open configuration to tie each together with first back tie member 182 and second back tie member 184 (both shown in
In further embodiments, first back tie member 182 and second back tie member 184 may also have a closed configuration and an open configuration similar to tie members 160 and 162 as described above. Protective covering 308 and pull tab 306 are also provided for first back tie member 182 and second back tie member 184. In further embodiments, protective covering 308 and pull tab 306 may be provided for some or all of first front tie member 160, second front tie member 162, first back tie member 182 and second back tie member 184.
In the example embodiment, back collar portion 504 is similar to a crew neck collar style while front collar portion 502 is similar to a mock turtleneck collar style. More specifically, back collar portion 504 is positioned at the base of the wearer's neck (e.g., at the neckline) while front collar portion 502 extends above the wearer's neckline and covers a portion of the wearer's neck. The front collar portion 502 may include elastic material to provide a secure fit around a portion of the wearer's neck. By extending above the wearer's neckline, front collar portion 502 enables portions of the wearer's clothing extending above the wearer's neckline, such as a dress shirt collar, to be more fully covered and protected from sources of infectious agents (e.g., blood, bodily fluids, secretions) when the wearer interacts with patients.
