  • Patent number: 4614000
    Abstract: A patient care undersheet includes a minimum number of support points in order to keep a bedridden patient from developing decubitus ulcers. The undersheet preferably comprises a bottom layer having a number of conically shaped bubble-like supports and a top layer comprising a non-woven fabric. An adhesive material connects the non-woven fabric to the bubble-like supports in such a manner that under pressure the bubble-like supports under pressure do not move with respect to each other. The bubble-like supports are air tight so that the undersheet does not collapse under the pressure of a patient's body. The area of contact of the top of the bubble-like supports to the non-woven fabric is approximately 40% of the total top surface of the undersheet. A patient only has to move a very small distance before a new area of skin is supported by the undersheet.

  • Patent number: 4360015
    Abstract: A multilayer absorbent bandage and process for making the same having two absorbent layers separated by a grid material and covered on one side by an exterior layer which contacts the wound surface and on the other side by a moisture resistant barrier. The bandage is designed to maintain its structural integrity while being capable of absorbing large amounts of fluid.

  • Patent number: 4350246
    Abstract: A process for specially treating the surfaces of absorbent fibrous surgical products such as towels, surgical drapes and the like. After the subject treatment, the products formed can be folded, stacked and packaged without appreciable fiber entanglement developing between contiguous surfaces of the products. Importantly, the products can be subjected to sterilizing radiation while folded in their package, and may thereafter be readily unfolded without sticking or blocking as might otherwise result from the exposure to sterilizing radiation.

  • Patent number: 4275719
    Abstract: A surgical procedure and apparatus therefor wherein a patient to be operated on is first wrapped with a plastic film sheet which is adhesively sealed to the patient's body remote from an operating area on the body, and is also sealed against an incision site on the body at the operating area. A sterilized atmosphere is provided beneath the film sheet for contacting the patient's skin. Another sterilized atmosphere is provided within a region substantially adjacent the body including the incision site, thereby enabling a surgeon to cut through the film sheet and into the patient's body with minimal risk of infection. Extensive and costly operating room sterilization procedures are thus significantly reduced, and patient comfort, as well as treatment, can be enhanced by controlling the temperature and humidity of the atmosphere provided beneath the film sheet.
