Abstract: A non-stretching wound dressing is provided for use with a patient. The wound dressing includes a cover sheet having top and bottom sides, a thin film sheet formed on the bottom side of the cover sheet, the film sheet having first and second ends and an adhesive side, and a carrier sheet in adjacent contact with the adhesive side of the thin film sheet. The dressing also includes a first gripping tab attached to one end of the thin film sheet and disposed between the film sheet and the carrier sheet for separating the carrier sheet from the film sheet with the cover sheet remaining affixed to the film sheet. A second gripping tab is attached to the top side of the cover sheet and at one end of the cover sheet so that pulling on the second gripping tab releases the cover sheet from the film sheet with the film sheet remaining in place on the patient.

Abstract: An apparatus suitable for the continuous preparation of a polymer-based cellular foam sheet of a predetermined thickness wherein the foam is produced from a reaction product capable of curing at ambient temperature formed by the reaction of a reactant composition including a prepolymer and water, the apparatus including: a means for reacting the reactant composition, a continuously moving substrate for receiving a quantity of the reaction product; a means for depositing the quantity of reaction product onto the substrate to form a rising foam sheet; a means for compressing the rising foam sheet to a predetermined degree, the compressing means being spaced from the depositing means; and a curing means spaced from the compressing means and providing for a rising of the foam sheet exiting from the compressing means to provide a porous foam sheet having the predetermined thickness.

Abstract: A non-stretchable wound dressing has a flexible, non-stretching cover sheet having adhesive on one side thereof, and having two spaced strip-form gripping tabs at opposite ends thereof. The cover sheet covers a urethane wound dressing with the adhesive of the cover sheet being in contact with the urethane, and the urethane having an adhesive layer on an opposite side thereof. For storage and prior to application to a patient, the adhesive of the urethane wound dressing is in contact with a releasable surface of a carrier, such as cardboard. For application to a patient, one of the cover sheet gripping tabs is pulled so as to release the cover sheet and wound dressing from the carrier, the cover sheet preventing stretching of the wound dressing. The combination is then applied to a patient, with the adhesive of the wound dressing in contact therewith, again the cover sheet preventing stretching of the wound dressing.

Abstract: Device and related method for determining the surface area of a wound. The device includes a transparent sheet having a series of perforations defining first and second sections of the sheet which allow the first and second sections to be separated from one another along the perforations. The transparent sheet is folded along the perforations so that the two sections overlap each other, and the sections are substantially free of adhesive material. The second section includes indicia thereon which allow a user to determine the surface area of a wound after the outline of the wound or opening is traced thereon. Upon use, the device is placed over the wound or opening, with the first section toward the wound or opening, and the outline of the wound or opening is traced onto the second section.

Abstract: A continuous process for the preparation of a polymer-based foam sheet at ambient temperatures wherein the foam is produced from a reaction product capable of curing at ambient temperatures formed by the reaction of a reactant composition comprising a prepolymer, such as an isocyanate-capped polyether, and water, comprising:(a) providing a continuous substrate;(b) depositing said reaction product onto said substrate;(c) compressing said reaction subjecting said product to at least one compression of a predetermined degree after said reaction product has creamed but prior to the time said reaction product has finally cured; and(d) finally curing said reaction product.

Abstract: A hydrophilic foam composition comprising the in situ reaction product of an isocyanate-capped polyether prepolymer, a hydrophilic agent capable of absorbing water, an adjuvant comprising an alcohol, a wetting agent, and water.

Abstract: A machine for manufacturing a stud and eyelet assembly in a web that moves continuously between the eyelet die wheel and the stud die wheel. The eyelet magazine continually supplies eyelets from an eyelet hopper to the eyelet transfer wheel, which in turn continually supplies the eyelets to the eyelet die wheel. Likewise, the stud magazine continually supplies studs from a stud hopper to the stud transfer wheel, which in turn continually supplies studs to the stud die wheel. The eyelet or stud is held on the die of the die wheel and the stripper of the transfer wheel by a vacuum. The vacuum is applied from a vacuum source through ports in each wheel to the die or stripper interface with the eyelet or stud. The vacuum in a transfer wheel operates from the point it receives an eyelet or stud from the magazine until the point where the eyelet or stud in transferred to the die wheel.

Abstract: A monitoring electrode for attachment to a patient for use with electronic medical diagnostic and monitoring equipment has a laminate construction including a foam pad, a conductor carrier strip having a metallized conductor thereon adjacent to the foam pad, the conductor carrier and a portion of the foam pad being covered by a conductive film, also applied to the foam pad in the form of a strip. The surface of the foam pad and the exposed portion of the conductive film strip to be attached to the patient are covered with an adhesive layer. The foam strip has a recess in the periphery thereof forming a tab onto which the metallized conductor extends, to which a lead of the diagnostic equipment can be attached, such as by a clip.

Abstract: An EKG electrode is disclosed including a conductive ring positioned around a jelled foam member which is positioned against a surface of a metal contact. The ring may be formed of a conductive medical grade plastic or may be formed by plating a non-conductive ring with a conducting metal.

Abstract: A circular EKG electrode has a plastic woven fabric body to which is attached a two-part connector. A jel impregnated disk is positioned over one part of the connector. The entire electrode is sealed in a disposable plastic package.

Abstract: An improved EKG electrode and package has a rectangularly shaped foam body member which is sealingly adhered to a first side of a plastic liner. A gelled foam disk is centrally attached to the same side of the foam body member. A plastic sealing cap covering the gelled disk is attached to the other side of the polyethylene liner material. An electrical contact is centered with respect to the disk and passes through the foam body member. The inventive method includes the steps of punching a centrally located hole in the foam body member, attaching an electrical contact through said hole, applying a foam disk to the body member, adjacent one side of the electrical contact, injecting gel into said disk, and sealingly applying a formed plastic cap over the gelled disk.

Abstract: A disposable biopsy needle, particularly for bone marrow biopsy sampling utilizing a metal cannula and stylet structure, and which otherwise may be formed from inexpensive material such as a suitable plastic. Suitable high production techniques, such as injection molding, may then be employed in the production of the remainder of the components of the structure, whereby the final product not only is of excellent design construction for the intended purpose, but also is of exceptionally low cost in manufacture, readily permitting its disposal following a single use.

Abstract: A device for occluding a fluid passageway such as a blood vessel, particularly a human blood vessel, which is of the balloon type, adapted to be inserted, by means of a catheter structure, into a blood vessel and moved thereby to the desired point of occlusion, at which the ballon is expanded by means of a fluid conducted through the catheter, thereby firmly securing the occlusion device to the vessel side wall. Novel means are provided, including a dual valve mechanism for insuring the retention of the expanding fluid in the device, thereby providing efficient sealing of the balloon to substantially eliminate the possibility of fluid leakage upon separation of the occluding device from the inserting catheter structure.
