14 Claims, 10 Drawing Figures 1 SURGICAL GOWN AND METHOD OF FOLDING BACKGROUND OF THE INVENTION This invention relates to gowns particularly adapted for use in surgical and medical procedures requiring sterility and to a method of folding such gowns to insure sterility and accessibility.

The gowns worn by medical personnel in'medical and surgical procedures have traditionally performed two important roles. First, they have prevented the clothes of the wearer from becoming saturated with blood or other fluids during these procedures. More importantly, however, these gowns have also served to protect the patient, the instruments involved in the procedure, the other personnel and, generally, the entire operating area from contamination by microorganisms unavoidably present on the clothes of the wearer.

Beyond the traditional consideration of maintaining sterility, however, a definite need has arisen, because of the advances of technology and the increasing sophistication of the operating procedures themselves to provide a surgical gown that will not only insure sterility but will also maintain its sterility while being moved from one place to another within the operating area, and may be donned with the efficiency and speed necessary in modern procedures.

open from the top downward, presenting an exterior uncontaminated surface. Though the gown of this invention does provide a method of folding and unfolding which insures sterility, it has several disadvantages and does not solve the problems of quick and easy accessiunfolded and in position for vesting by the wearer, the

In the past, surgical gowns closing at either the front a or the back have been folded by hospital personnel with an attempt to expose only the interior surface of the gown which will come in contact with the wearer's clothing, thus retaining the sterility of the exterior surfaces prior to use. However, gowns folded in this manner afford no easy means of unfolding and vesting without contaminating the desired sterile surface. Such haphazard folding methods provide no quick or apparent hand holds for the nonsterile circulating nurse to grasp and open the gown for the surgeon and provide manner are always liable to come unfolded and contaminated accidentally while being moved about the operating room by the nonsterile personnel. Such accidental contamination may occur simply because it is so difficult to determine where the top of the gown is located or where it will fall when unfolded.

Some attempts have been made to solve the problems presented by the necessity of having a surgical gown which unfolds easily in a predictable manner I and yet remains completely sterile. One such method of making a gown and folding is shown in US. Pat. No. 3,359,569 to R. J. Rotanz et al., issued Dec. 26, 1967. This patent illustrates a gown made with hand grasping pockets having interior surfaces which may come in contact with nonsterile personnelor areaswithout endangering the sterility of the exterior gown surface. The gown containing these pockets is folded in such a manner that the interior surface is exposed and the pockets face up. When the nonsterile personnel insert their hands into the pockets and shake the gown, it falls sleeves 3, as is shown in FIG. 7, hang at an angle parallel to that of the body of the wearer. This position requires considerable acrobatic movement and much time on the part of the wearer to insert his hands and arms into and through these sleeves. The angle at which the sleeves of the Rotanz gown hang make it nearly impossible for a wearer to don the gown himself, as must often be done in obstetrical procedures where a circulating nurse may not be available.

DESCRIPTION OF THE INVENTION The surgical gown and method of folding of thisinvention overcomes the problems and disadvantages presented by the gowns and methods of folding previously used in surgical and medical procedures. It provides a gown and a method of folding this gown which maintains the exterior surfaces of the gown in a completely sterile condition prior to use butwhich provides for predictable and controlled unfolding and quick, easy andunassisted vestiture by the wearer.

This invention achieves these desirable advantages by a unique method of folding a gown including a body portion having two back panels and a front panel, two sleeve portions integral with the body portion, aseptic closure means'and a belting means. The method of folding which permits sterility, predictable unfolding and easy manipulation'and donning of the gown is accomplished by a first folding inwardly of creased grasping flaps forming the insidev edges of the opposite back panels of the gown and attaching these flaps at their upper ends to the neck or shoulder of the gown to maintain'them in folded position. A longitudinal inward fold of the back panels of the gown is made toward the center, before or after which each sleeve portion is pulled inwardly through itself in inside-out fashion until the ends of the sleeve portions lie adjacent and parallel one another at a certain distance inward from their point of attachment to the body portion of the gown. This sleeve folding forms openings for the wearers arms near this point of attachment. The body portion of the gown is folded upwardly in a plurality of sections from its bottom until the top edge of one section is adjacent a line drawn between the armpits of the parallel sleeve portions. The upper section of the gown, including the sleeve portions and the part of the front panel underlying them, is then folded downwardly over the previously folded sections. Before or after-this fold, the collar points or the ends of the neck of the gown are folded downwardly or tucked between the oppositely folded sections. The arm openings formed in the sleeve portions and lying at each end of the gown are then folded to the center of the gown so that these openings are adjacent and facing one another. The gown is then a again folded in half upon itself so that these arms openings are facing the same direction. At this point, the gown presents a compact package which exposes only its interior surfaces to the environment, and which may not be-accidentally shaken open or come unfolded inadvertently as it is moved from place to place. To

open the gown, the-weare'rmerely inserts his right hand a short'distance into the right sleeve arm opening and his left hand a similar distance into the left sleeveopenconsequential portion of the exterior surface of the neck,if necessary.

The'body of the wearer is then completely encircled in the gown securely closed by a belt means which is contained in an overwrap or a pouch which has been folded inside the gown in such a manner that it remains ing and grasps a'piece of the interior surface material within-the openings between hisfingers.

Inthis position, the wearer thenmoves his arms apart upwardly and outwardly, causing the sleeve portions .and bodyportion of the gown to be moved apart. The

gown proceeds to gently unfold with its exterior surface unfolding away from the body of the wearer so' that its sterility is not in danger of contamination.

The gown is well marked for the convenience of the completely sterile during unfolding. The nonsterile I nurse grasps the overwrap and walks around the wearer of the gown, unfolding the: sterile belt fromwithin the .overwrap or pouch as she-moves. The wearer merely takes the lastportion of the belt within the overwrap while the nonsterile nurse disposes of the'overwrap and wearer before unfolding so that when the gown is opened properly, the top of the .gown'will be up and the bottom will fall toward the floor. Thus, thereis no danger of confusingthe portionsiof-the gownand opening it upside down;

trolled by the person opening the gown and permitting this person to see the direction and speed at which the gown is unfolding and to thereby avoid any accidental contamination by'contact with parts of the-' tableior other personnel in the room. I H a A major advantage of this surgical gown and method of folding is thatthe wearerinserts his arms directly into the sleeves of the gown, thus eliminating the neces. sity to search for these sleeves or to attempttoposition i A distinctadvantage of this method of folding is that the gown unfolds slowly, or at a speed that may be conhisv arm in a gown sleeve which hangs parallel to his body, and may begin above "his-shoulder level and end below'his waist. The ability of thewearer to insert his arms directly into the interior of the sleeve portionsprevents any problem of binding which occurs from loosely hanging gown sleeves such as those necessarily I available on gowns folded by prior methods.

-When the gown of this invention is unfolded, the wearer's arms are already in the sleeves and little effort or time is required for himto move his arms to-a gloving position. This invention requires no specially .manu-' factured gown having grasping pockets so its cost may be-kept to aminimum.

Complete sterility of all exposedor outside surfaces of this gown is preservedduring unfolding and closure because of the unique method of attaching the upper part of the creased grasping flap near the top portion of the body of the gown near the shoulder or neck. Once the wearer has his arms into or through the sleeves, the

' nonsterile circulating nurse may'grasp the interior portions of the creased flaps which stillface outward, un-

sn'ap them from their. temporary point of retention of the gown, unfoldthem and overlap these flapsover one another, finally snapping the tabs of'the closure means on one of these flaps on the closure means disposed on theopposite back panel to completely close the -gown. Because of the manner in which the creased flap is at- 'tached to the neck, the nonsterile nurse can grasp a portionof the interior surface and aseptically close the gown-at the neck-whiletouchingonly aminimal and in- -ties the belt in-any fashion tightly'abouthis waist in a comfortable position.

Accordingly, it is an object of this invention to. pro.-

vide a surgical gown and method of folding in which only the interior surfaces of the gown are exposed to the surrounding environment after folding.

It is another object of this invention to provide a surgical gown and method of folding in which the folded gown may be grasped and 'moved from place to place before use without danger of inadvertently unfolding. It is a further object of this invention toprovide a surgical gown. and method of folding whichallows the loosely hanging sleeves.

It is 'astill further object of this invention to provide a surgical gown and method of folding which permits aseptic closure and assistance in belting the gown by a nonsterile nurse without contaminating the exterior front or back surfaces of the gown.

It'is also an object of this invention to provide a surgical gown and methodof folding which permits unfolding of the gown in a controlled," deliberate manner.'

It is still another object of this invention to provide a surgical gown and method of folding which requires no special manufacture to achieve its unique folding .and- .unfolding.

i tive and surest means of closing,-'the method of folding Referring now to the drawings and more particularly to FIG. 1, one embodiment of a surgical gown to be folded according to the method of this invention is shown at 10.

This gown 10 has a body portion 12 formed from a seamless piece of material, such as cloth or disposable paper. This body portion 12 includes a front panel 14 to cover the front portion of the wearers body when the gown is worn as shown in FIG. 10, a right back panel 16 and left back panel 18. There are no definite boundaries separating the front panel 14 and

back panels

16 and 18 since the body portion 12 is seamless, but these panels do describe definite front and back areas of the gown when it is worn as shown in FIG. 10.

A right sleeve portion 20 and a left sleeve portion 22 are attached to the body portion 12 of the surgical gown 10 by sewing, gluing or other acceptable means of attachment. After attachment, the

sleeve portions

20 and 22 are for all purposes integral with the body portion 12. The

sleeve portions

20 and 22 terminate at their outermost ends in expansive cuff means 23 which of the right back panel 16 and left back panel 18 and a formed from the material of the body' portion 12. These flaps 24 may be precreased at a point a given distance inward from the edge of the

back panels

16 and 18 and along a line substantially parallel to the'longitudinal axis of the gown 10. The

back panels

16 and 18 are then folded on this creased line to form the grasping flaps 24 which aid in the aseptic closure of the gown l0 after it is put on. The body portion 12 of the gown 10 has flap closing means 25 disposed on the upper portion of the body 12 of the gown 10 attachable to aseptic closure means 26 disposed on the upper portion of flaps 24 which may be used to temporarily maintain creased grasping flaps 24 in a folded position prior to closing of the gown. The complementary aseptic collar closure means 26 disposed near the neck or collar 31 on the respective grasping flaps 24 on

panels

16 and 18 on either side of the body portion 12 act, when joined together, to close the gown at the neck as shown in FIG. 10.

In this particular embodiment of the gown 10, a belting means 28 is also shown attached to the body portion 12 on the right-hand side of the front panel 14 thereof. This belting means 28 may be attached by sewing or gluing, although gluing is preferred for gown uses requiring high sterility since holes made in the body portion 12 by sewing present passageways which allow the possible passage or microorganisms from the clothes of the wearer into the operating field. This belting means 28 includes a belt overwrap 27 having a belt 29 made of cloth or paper material folded therein. A

and gown features described in this invention are also applicable to various other embodiments of surgical gowns, including those used in procedures not requiring such a great degree of sterility. For example, another embodiment of this surgical gown which may be folded by the same method uses a pressuresensitive tape positioned near the edges of one or both of the creased flaps 24 on the

back panels

16 and 18 of the gown which may be pressed to the clothing of the wearer before closure of the aseptic means 26 at the neck 31 of the gown to hold the gown in a temporarily closed position to facilitate complete aseptic closure. Such pressure-sensitive tape could, of course, be used on the previously described preferred embodiment of the gown 10. The aseptic closure means 26 at the neck of the gown may also include, besides snaps, Velcro strips disposed on the

opposite back panels

16 and 18 of the gown near the neck 31. This second embodiment of the gown might have a belting means 28 including, instead of the overwrap 27 and belt 29 shown in FIG. 1, one or more ties sewn near the edges of the right back panel 16 and left back panel 18 in corresponding positions which, when tied, act to effectively close the gown at the back.

A third embodiment of the gown is often used in obstetrical and gynecological procedures which do not require as great a degree of sterility as various other surgical procedures. This type of gown often has sewn seams called inside seams which reduce the expense of its manufacture. In addition, it may have free hanging ties used as a belting means 28. It is significant, however, that in obstetrical procedures, the doctor must often gown himself without the assistance of a nonsterile or circulating nurse. In this use, the method of folding the gown set forth in this invention is extremely important since it is essential that the doctor be able to quickly and easily put on the gown by himself. As mentioned previously, this unique method of folding enables a doctor to gown himself without wasting valuable time exerting a great amount of effort in finding hanging sleeves or avoiding contaminating sterile areas.

The first step in the method of folding the various embodimentsof a surgical gown according to this invention is to place the gown 10 in the position shown in FIG. 1 so that the exterior surfaces which will be exposed to'the patient and the other personnel in the operating area are facing upward. The grasping flaps 24, which are formed at the edges of

back panels

16 and 18, are then folded inwardly along a crease substantially paralleling the longitudinal axis of the gown 10 ad located a definite distance inward from the edge of the

back panels

16 and 18, so that the grasping flaps 24 are formed having their interior surfaces, i'.e., those surfaces which will face toward the clothes of the wearer, facing upward. The grasping flaps 24 are maintained in their folded position by attaching flap closing means 25 including a snap or Velcro strip located on The next step in folding the gown 10 is shown in FIG. I

2. The

back panels

16 and 18 are folded longitudinally inwardly upon the exterior surface of the front panel 14 of the gown toward the center of the gown. When such fold is completed, a small distance may remain between theopposite edges of the right back panel 16 and left back panel 18 as shown in FIG. 2.

The

sleeve portions

20 and 22 of the gown are then pulled inwardly through themselves from the position shown in FIG. 1 until the expansive cuff means 23 lie parallel and adjacent one another as shown in FIG. 2. The

sleeve portions

20 and 22 must be parallel, flat and substantially perpendicular to the longitudinal axis of the gown 10 to prevent binding when the gown is unfolded. The

sleeves

20 and 22 should be pulled inwardly through themselves in this inside-out fashion approximately 6 inches from the shoulder seam. While the cuff means 23 may overlap, they may also, as shown in FIG. 2, simply lie along the same line opposite one another, depending upon the size of the gown. When the sleeves are pulled through one another in this fashion, a right arm opening 32 is formed by the right sleeve portion 20, and a left arm opening 34 is formed by the left sleeve portion 22. It is noteworthy that the step of pulling the

sleeves

20 and 22 inside-out may be performedprior to. the longitudinal folding of the right back panel 16 and left back panel 18 previously described.

The gown 10 is then folded from its bottom upwardly upon itself in three folds indicated by F4, F and F6 in FIG. 2. The sections formed by the folds should be substantially equal in area to provide uniform unfolding. Again, these folds are inside folds so that the exterior surface which must be maintained in a sterile condition is at all times contained on the inside of the folded gown 10.

When these last three folds have been accomplished, the collar tabs 30.which contain the aseptic collar closure means 26 may be folded downwardly on top of the I

parallel sleeve portions

20 and 22. At this stage, the

gown presents the appearance shown in FIG. 3. Next, the top section of the gown which includes the in-' section and the previously folded sections of the body portion 12.

The

arm openings

32 and 34, shown in FIG. 4, are then folded inwardly along fold lines F8 toward the center of the gown 10 until the gown is in the position shown in FIG. 5. The last fold is then made along fold line F9, shown in FIG. 5, by backwardly folding the gown in half at the center so that the

arm openings

32 and 34 are parallel and facing in the same direction as shown in FIG. 6. The gown 10 is now ready for sterilization by such means as ethylene oxide. In this position,

the gown 10 may be transported from place to place,

without danger of unfolding and is ready for immediate use in medical and surgical procedures. Alternatively,

it may be stored within a protective wrap and still retain the sterility of the exterior surfaces, which are folded inside, for along period oftime.

In its folded position shown in FIG. 6, the gown may be easily opened and put on by one person by inserting,

as shown in FIG. 7, the right-hand arm into the right arm opening 32 and sleeve 20 and the left handand apart in an outward and slightly upward manner so that the gown slowly unfolds as shown in FIG. 8. The person being gowned then is able to easily work his arms for ward toward the cuff means 23 as far as desired, depending upon whether gloving will take place before or after he inserts his hands through the cuff means 23.

Once the wearer has the gown in the position shown in FIG. 9, the nonsterile or circulating nurse or thegown wearer himself takes hold of one of the grasping flaps 24 near its upper end, disconnects it from its temporary position where it has been held by the flap closing means 25, pulls it around the back of the neck', always touching the outside facing but interior surface of the grasping flap 24, and fastens the aseptic closure means 26 positioned on it to the complementary aseptic closure means 26 disposed on the opposite grasping flap 24 which has been undone in the same fashion.

The aseptic closure means 26 disposed on these opposite grasping flaps 24 may consist of complementary snap means, Velcro pressure strips or pressure-sensitive tape. As mentioned in connection with the second embodiment of this gown, pressure-sensitive tape located on the

back panels

16 and 18 near the midsection of the body portion 12 of the gown may be pressed to the clothing of the wearer to temporarily hold the gown in the closed position so that the attachment of the aseptic closure means 26 at the neck may be performed more easily.

Since the only surface of the gown handled during the closing of the gown at the neck is the interior surface exposed by the fold of the grasping flaps 24, the gown may be closed by the nonsterile or circulating nurse without affecting the sterility of any of the exterior surfaces.

Once the gown has been closed at the neck, the circulating nurse'then grasps the overwrap 27 of the'belting means 28 and walks around the gown wearer, hold- I ing onto the overwrap 27 while unfolding the belt 29 contained within the overwrap 28. The wearer takes the sterile ends of the belt 29 and ties them together at the front in any manner that is desirable and comfortable as shown in FIG. 10. The position of the aseptic closure means 26 on the upper end of the creased flap 24 is such that when the closure means 26 are properly attached to each other, the grasping flap portions 24.

overlap so that the back of the gown is completely enclosed.

The other embodiments of the construction of the gown itself, described previously, may use free hanging ties instead of the belting means 28 to secure closure of the gown. After the neck is closed in these types of gowns, the wearer merely secures the ties as desired at his back.

It is obvious that the steps used in folding the gown to obtain a package which may be directly opened, as shown in FIG. 8, so that the arms of the wearer are already partially inserted into the gown when it is opened, and which may be carried from place to place without unfolding, may be varied somewhat and still achieve the result and advantages desired. Thus, the sequence of operations in this method of folding is not as significant as the operations themselves.

While the invention has been described in relation to preferred embodiments thereof, it will be apparent to those skilled in the art that the details of the gown and method of folding are capable of wide variation without departing from the spirit and scope of the appended I claims.
