  • Publication number: 20120083536
    Abstract: An adhesive composition having dispersed therein a broad spectrum antimicrobial agent for use in medical applications, such as an adhesive for surgical drapes, wound dressings and tapes, is provided. The adhesive is composed of acrylic polymers, tackifiers and a preferred antimicrobial agent, diiodomethyl-p-tolylsulfone. The subject adhesive composition may be formulated as either an essentially solventless hot melt, or as a solvent based system wherein an emulsion of the antimicrobial agent and the removal of excess solvent is avoided.

  • Publication number: 20100170520
    Abstract: A surgical drape including a clear plastic substrate which is substantially impervious to liquids. The substrate is positionable over a patient with a first surface of the substrate generally engaging the patient. The substrate has an aperture formed therein which affords access to a location to which an incision is to be made in the patient. The drape further includes an absorbent lamina which overlies a second surface of the substrate which faces in a direction opposite that in which the first surfaces faces. A clear plastic patch, also substantially impervious to liquids, is sealed relative to the substrate along a line encircling the aperture. The patch can have a hole, either initially provided at manufacture or created by a surgeon during the procedure, which is at least partially coextensive with the aperture.

  • Publication number: 20040003818
    Abstract: A surgical drape manufactured or fabricated from a polymeric film having a low glare finish and a predetermined coloration for reducing the luminous intensity of light reflected from the surface thereof is provided. Such surgical drape thereby minimizes reflectivity therefrom, and thus eye strain and fatigue. The subject invention includes the use of colorants, dyes, pigments, etc. to form translucent polymeric surgical drapes that absorb a selected range of wavelengths from surface reflected light. More particularly, the use of coloring agents in combination with a textured surface yield a surgical drape possessing reduced luminance and glare, thereby mitigating eye strain and fatigue. The preferred range of reflected light, in order of preference, is 625-700 nm, 520-560 nm, 450-520 nm, 400-450 nm, 600-625 nm, and 560-600 nm.

  • Patent number: 6244268
    Abstract: A configuration of surgical drapes for convenient dispensing and handling from a container. The configuration includes a continuous rolled length of surgical drapes having opposing major and minor longitudinal edges. Each drape of the continuous roll is separable from adjacent drapes by longitudinally spaced apart lines of weakness throughout the continuous length of surgical drapes. The continuous rolled length of surgical drapes includes an adhesive strip adjacent the major longitudinal edge of the continuous rolled length of surgical drape. The adhesive strip in turn carries a removable release liner thereover which preferably partially overhangs the adhesive strip. The continuous rolled length of surgical drapes further has an accordion pleat fold to thereby reduce the stored and dispensed width of each drape of said continuous length of surgical drapes.

  • Patent number: 5162040
    Abstract: A sterile, medical dressing package (10), a method of applying the dressing (10) to a patient, and a method of configuring and packaging a sterile, medical dressing (10). The package (10) includes a dressing sheet (12) and a pair of cover sheets (14). Release portions (38) of the cover sheets (14) overlie, and are adhered to, lateral portions (36) of an adhesive face (16) of the dressing sheet (12). Tab portions (40) of the cover sheets (14) are folded back upon their respective release portions (38). The tab portions (40) extend away from a central portion (34) of the dressing sheet (12). The central portion (34) of the dressing sheet (12) is folded back upon, and adhered to, a tab portion (40) of one of the cover sheets (14).

  • Patent number: 4886165
    Abstract: A disposable hinged box (2) for surgical articles. The container (2) has certain design features to facilitate accounting of small surgical implements. An oblique bifurcation between the container cover (6) and container bottom (4), together with a guard (36, 38) forms a cradle within the cover for retaining implements therein. The container is particularly suited for holding syringes within the container cover (6) and accounting for needles, or suture, within the container bottom (4).

  • Patent number: 4745915
    Abstract: A disposable surgical drape (10). It includes a tubular-shaped protective film (14) with a pull-tab (24) which lends itself to remote removal from an adhesive layer (20) on the protective film (14) so that the drape can be secured to a patient (22) without contamination of the incision area. An embodiment of the drape (10) comprises a protective film (14) which, when circumferentially spaced portions thereof are bonded together by, for example, a heat seal (15), defines a channel (16) which can function as a fluid conduit to remove bodily fluids from the surgical incision area.
