Z Claims. (Cl. 206-63.2)
The present invention relates to improvements in surgical dressings, and it relates more particularly to an irnproved surgical dressing and a protective envelope therefor which may be opened simply and easily to permit the application of the surgical dressing at any -desired position.
The present application is a continuation-in-part of copending application Serial No. 440,170, led lune 29, 1954, and relating to a bandage package, now matured into U. S. Patent No. 2,752,038; issued lune 26, 1956.
It has long been conventional to package surgical dressings individually in order to protect them from external contamination before application. In recent years, it has become a common practice individually to package a strip of adhesive tape carrying a surgical dressing such as a gauze pad or compress, either treated or untreated. These individually packaged adhesive tape carried dressings are widely used domestically yand for first aid purposes and are usually self-applied. Such being the case, it is necessary that the dressing be easily removed and applied with a minimum of dexterity and with little exposure of the dressing per se prior to application. However, individually packaged surgical dressings of this type have heretofore been characterized by their complex-ity and diculty of employment and application. The opening of the containing envelope is usually awkward, and separate operations are generally necessary to remove the adhesive and the protective materials before the dressing may be applied. Another disadvantage of the conventionally packaged dressing is its generally untidy arrangement from the standpoint of the number of separable elements which must ultimately be disposed of when the dressing portion is removed and applied.
It is thus a principal object of the present invention to provide an improved packaged surgical dressing.
Another object of the present invention is to provide an improved, individually packaged dressing including an adhesive tape carrying a pad and a disposable envelope protectively covering the dressing.
Still another object of the present invention is to provide an improved, individually packaged first laid dressing characterized by its simplicity and ease of application.
A further object of the present invention is to provide an improved, individually wrapped first aid dressing including a gauze pad mounted on ia strip of adhesive tape and packaged in a disposable envelope and characterized in the ease of removal of the dressing from the envelope and its subsequent application.
A still further object of the present invention is to provide an improved, individually packaged first aid dressing including an adhesive tape carrying a lcompress or the like, and a sealed protective envelope enclosing the dressing and characterized by the dressing being easily removable from the envelope and readi'ed for application, leaving the open envelope disposable as a `single unit.
Other and further objects Iof the present invention will become apparent from a reading of the following description taken in conjunction with the accompanying drawing, whereinice Figure 1 is a perspective view, partially broken away, of an improved individually packaged first aid dressing illustrated in closed condition and constituting a preferred embodiment of the present invention;
Figure 2 is a perspective view illustrating the application of the first aid dressing to a finger;
Figure 3 is a sectional view taken along line 3 3 of Figure 1.
The present invention broadly contemplates the provision of a packaged surgical dressing comprising a pair of superimposed panels separably sealed along their confronting edges to define an envelope, .a strip of adhesive tape having a dressing positioned on the adhesive face thereof, said tape being disposed in said envelope and having an end thereof separably secured to an end of one of said panels, the interior face of one of said panels having a non-adherent surface -confronting the adhesive Isurface of `said tape.
In accordance with a preferred embodiment of the present invention, there is provided a long strip of a frangible material folded transversely at substantially its mid-point to define a hinge separating the strip into front and rear panels. An adhesive tape carrying a suitable dressing ton its adhesive face has its opposite adhesive-free face superimposed upon the rear panel and is narrower than said panel. The free end of the rear panel is folded over to engage the end of the adhesive tape remote from the panel hinge.l The inner face of the front panel is coated with a band of material non-.adherent to the adhesive face of the tape. The two panels are sealed along their side edges and along aline inwardly of their free ends to form a sealed venvelope having finger tabs, the non-adherent band confronting the adhesive face of the tape.
Referring now to the drawings which illustrate a preferred embodiment of the present invention, numeral 10 generally designates a strip of frangible material such as paper or the like provided with a transverse fold line 12 intermediate its end-s defining a hinge and dividing the str-ip 10 into a front panel 14 and a rear panel 16. Strip 10 is coated or otherwise provided o-n its inner face with a thin layer 18 =of a non-adherent material, said layer 18 extending to the ends of the strip 1i) and being spaced yfrom the side edges thereof to provide the noncoated longitudinal borders 20, 20. The non-adherent coating may be formed of polyethylene, polytetraiiuoroethylene or other suitable substance which will not adhere to the adhesive surfaces of the conventional adhesive tapes.
The surgical dressing, per se, consists of a strip 22 of adhesive tape formed of a woven fabric or plastic backing having a llayer of adhesive on a face thereof in accordance with conventional practice. A suitable dressing 24 which may be a gauze pad, compress or other dressing, either treated or untreated is positioned on the adhesive face of the tape 22. The tape 22 is no wider than the non-coherent coating 18 and is superimposed upon the rear panel 16 in registry with the coating 18 its adhesive free face confronting the panel 16 and the ends of the tape 22 extending substantially to the hinge 12 and to a point short of the free end of the rear panel 16. The free end of the rear panel 16 is folded over to engage the corresponding end of the tape 2-2. and to define a finger tab 26. The front and rear panels 14 and 16 are folded along the hinge 12 t-o confronting relationship, san-dwicliing between them the dressing carrying adhesive 22. The `side edges of panels 14 and 16 are sealed to eac'h other by a suitable cement .or in any other conventional manner and the portions of panels 14 and 16 remote from hinge 12 are likewise sealed to each other along a line spaced from the free ends of the panels to complete an envelope fully enclosing the dressing carrying tape 3 22 'and providingginger:.tabsr26 and 28 respectively. Tabs 26 and 28 facilitate the opmeningmof the envelope, tab 26 engaging an end of the tape 22 as at 30, and being h-eld following the opening of the envelope.
