ATTORNEYS United States Patent O 3,609,767 SURGICAL GOWNS Carl R. Grosz, 807 E. Carl Ave., Baldwin, N.Y. 11510 Filed Oct. 29, 1969, Ser. No. 872,005 Int. Cl. A41d 9/00 US. Cl. 2114 6 Claims ABSTRACT OF THE DISCLOSURE A wrap-around flap is joined to the front of a back overlap surgical robe along a substantially vertical seam to maintain the back of a surgical gown in a sterile condition. The flap includes arm holes adjacent the upper edge thereof through which the users arms are inserted as the flap is wrapped about him. After a robe having a donning access opening secured by a closure means at its back is donned, the closure means is rendered effective by an assistant who is not sterile. The flap is subsequently wrapped about the user covering the contaminated back of the robe. While the flap is being wrapped about the user, he inserts his arms through the arm holes. The free vertical edge of the flap is then secured to the front of the gown. Thus, the flap serves to maintain the back of the gown in a sterile condition and provides two or more layers of material in the front.

BACKGROUND OF THE INVENTION (1) Field of the invention Sterile coverings for surgical gowns.

(2) Background of the invention Surgical gowns which are commonly used in hospitals are usually donned by the user with the aid of a nurse or assistant who is not completely sterile. These commonly used gowns are closed (i.e. have no fastenerclosable seam) at the front and have a fastening device, e.g. snaps, ties or a slide or Velcro fastener at the back. Thus, although the front of the gown is sterile, there is an unsterile portion including and adjacent the fastener at the rear.

This is obviously disadvantageous in operating rooms where the danger of infection is maximal and where optimum sterile conditions are desired. It is apparent that with the present surgical gowns, persons present in the operating room, e.g. another surgeon, doctor, medical aide or nurse, may accidentally brush across the unsterile back of a gown during an operation, and thus the chance of infection from the unsterile portion at the back of a surgical gown is present.

There have been several attempts made to provide a completely sterile surgical gown. Of course, no matter how sterile the gown was, if the doctor was assisted in donning the gown, no portions touched by the other person would be sterile unless the assistant was also sterile. Most of the attempts to rectify this situation have been self-donning gowns, i.e. gowns which the user would don and secure himself and gowns with an easily contaminated flap.

SUMMARY OF THE INVENTION It is an object of the invention to provide a sterile surgical gown of the character described which is simple in construction yet can be fabricated by mass production methods at an appreciably lower cost than prior devices designed to serve the same function.

It is another object of the present invention to provide a sterile surgical gown of the general character described wherein a sterile overlay flap is provided for covering any portion of a surgical robe which was or might have been contaminated when the robe was donned and fastened.

A further object of the present invention is to provide a sterile surgical gown of the general character described wherein a sterile covering flap is secured to a surgical robe distant from the robe donning access opening, said flap being structured and disposed to be wrapped about the robe to provide a sterile covering over the access opening.

Yet another object of the present invention is to provide a sterile surgical gown of the character described which includes a sterile overlay flap of a length sufiicient to completely wrap about the user, and which serves to cover any previously contaminated portions of the gown.

Other objects of the invention in part will be obvious and in part will be pointed out hereinafter.

The invention accordingly constitutes the features of construction, combinations of elements and arrangements of parts which will be exemplified in the surgical gowns hereinafter described and of which the scope of application will be indicated in the appended claims.

FIG. 6 is a greatly enlarged fragmentary sectional view taken substantially along the line 6-6r of FIG. 1 and illustrating the structure of the Velcro closure means which is utilized to detachably anchor the free vertical edge of the flap.

DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention in part arises from the realization that even present day highly sophisticated operating techniques leave much to be desired in insuring against infection during operations. It has been previously fallaciously felt that only the portions of the surgical gown which faced the operating table had to be maintained sterile. The present surgical gowns were developed to overcome the oversight that the rear or back of the surgical gown which is worn in the operating room is usually contaminated by the non-sterile medical aide or assistant who helped the user into the gown and fastened the gown at the rear.

Referring now in detail to the drawings, the reference number denotes a surgical gown constructed in accordance with and embodying the present invention. Said gown includes a surgical robe 12, preferably formed of linen, in the conventional manner, or of any other sterilizable limp flexible sheet material, and having sleeves 14, a neck opening 16, and a split seam extending the height of the robe at the rear thereof to provide a donning access opening. A suitable fastener such as a snap fastener joins the overlapping longitudinal edges 18 at the rear of the robe. The front of the robe is devoid of a vertical fastener-closable seam. The surgeon, nurse and other operating room personnel are assisted by a medical aide in donning their gowns. Prior to donning the gown, each scrubs down and is then assisted by the medical aide who fastens the rear split seam donning access opening of the robe adjacent the edges 18. In effect, the robe is donned backwards and unlike an ordinary coat, the longitudinal edges 18, which are separated to provide a donning access opening, are at the back of the robe.

In accordance with the present invention, there is provided in conjunction with the robe 12, a sterile wraparound fiap 24 which is attached to the robe 112 and which includes arm holes through whiich the users arms are thrust as the flap is wrapped across and over the unsterile rear portion of the robe 12. The flap 24 is substantially rectangular in configuration and includes parallel

vertical side edges

26, 27 and substantially parallel top and

bottom edges

28 and 30. The side edge 26 extends vertically for a distance about equal to or slightly less than the length of the gown 12 and is secured, preferably permanently, to the front 22 of the robe 12 toward the left side thereof. A suitable securing arrangement is stitching 32, although a removable fastener is also within the scope of the invention. It should be noted that the upper edge 28 of the flap 24 is at an elevation slightly above the top of the sleeves 14 and that the bottom edge 30 is at, or slightly above, the bottom edge of the gown 12. This assures that a maximum overlay of the wrap-around flap about the unsterile back portion of the surgical robe will be achieved.

As previously mentioned, the flap 24 includes right 34 and left 36 arm holes which are near but not at the upper edge 28. A detachable anchoring means for fastening the free vertical side edge 27 of the flap after it has been wrapped about the user is additionally provided. The aforesaid means illustrated in FIGS. 1, 3, 4 and 6 is a Velcro type fastener 38. As best illustrated in FIGS. 3 and 6, the Velcro fastener 38 includes two

elongate strips

40 and 42, one of which includes a multitude of upstanding tiny hooks and the other of which is formed with a multitude of upstanding tiny loops. One strip 40 is mounted on the inside surface of the flap 24 adjacent the free edge 27 while the other cooperating strips 42 is secured to the front of the flap 24 parallel to and near the free vertical side edge 27 in a position such that after the flap has been wrapped completely over the back of the robe, the strip 40 will be in registry with the strip 42. Once the two strips are in registry, a slight compressive pressure will couple the two strips in interlocking engagement and thus prevent opening of the flap.

The flap may be folded for storage with accordion type pleats (see FIG. 3) against the front 22 of the robe 12. After the robe is donned, the user himself opens the flap and thrusts his right arm and sleeve '14 through the right arm hole 34. The flap is then extended across the back of the robe, covering the unsterile fastener 20 and access opening. The left arm and sleeve 14 are then thrust through the left arm hole 36 after which the free vertical side edge 27 of the flap will be in front of the user and the

opposed strips

40 and 42 of the Velcro fastener 3-8 will be in registry so that the free side edge 27 may be anchored.

It should be noted that because the

arm holes

34 and 36 are spaced below the upper edge 28 of the flap, they serve to keep the flap from sagging at the sides of the user.

An alternate embodiment of the invention is schematically illustrated in FIG. 2 wherein the flap 24 is shown in a loose wrap-around position to better illustrate the manner in which the flap is utilized. It should be observed that in this embodiment, the free vertical side edge 27 of the flap is not anchored to the front of the flap by a Velcro fastener, but instead a series of vertically spaced pairs of tie strings 43 are utilized. In all other respects, the embodiment of FIG. 2 is identical to the embodiment previously described. In this figure the flap has been shown as standing away from the robe for clarity of illustration; in actual use, this flap lies against the robe.

A third embodiment which not only utilizes an alternate fastening arrangement for anchoring the free vertical side edge 27 of the flap, but, additionally, a modified donning arrangement, is illustrated in FIG. 5. In this embodiment, snap fasteners are utilized to anchor the free vertical side edge 27 of the fiap to the front of the robe. The snap fasteners include rows of male 42 and female 44 engaging members with one of the rows in a vertical line parallel to the side edges 26, 27 along the front of the =flap and the other members 44 are secured to the flap in a vertical line adjacent the free side edge 27 so that, after the flap is so wrapped about the user, the

members

42 and 44 will be in registry for mutual engagement.

It should be additionally noted that in the embodiment illustrated in FIG. 5 the flap 24 also includes a horizontal slit 46 interconnecting the left arm opening 36 with the free side edge 27. This slit permits the doctor or other operating room personnel to easily and rapidly wrap the flap 24 about the robe by eliminating the necessity of inserting ones left arm and sleeve through the left arm hole 36. In use, after the robe 12 has been donned by and secured to the user with the assistance of the unsterile medical aide, the sterile user unfolds the pleated flap, inserts his right arm and sleeve 14 through the right arm hole 34, then wraps the flap about the unsterile back portion of the robe, and, instead of inserting his left arm through the left arm hole 36, merely spreads the portions of the flap on both sides of the slit 46 so that his arm may pass through the slit from the free vertical edge 27 into the arm hole 36.

It is also within the ambit of the invention to provide a removable flap which may be -kept clean and sterile apart from the robe 12, and which may be attached or detached at the side edge 26 to the front of the gown 12. Any of the above mentioned fastening arrangements, i.e. Velcro strips, snap fasteners, or tie strings may be used to secure the side edge 26 of the flap to the front 22 of the gown. It will be observed that in all embodiments of the invention, one edge of the flap is secured, preferably permanently, to the front of the robe while the other edge of the flap is, after being draped over the previously crossed access opening of the robe, detachably anchored to the front of the robe or to the flap itself after a 360 wrap-around.

Thus it will be seen that there is provided a surgical gown which achieves the various objects of the invention and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the present invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein described or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
