Definitions

  • the operation room personal have been wearing protective clothing like gowns, head wear, face masks and glows to protect themselves and the patient from infections and as a general protection against blood and other body fluids.
  • the patient have been protected by different kind of drapes arranged to only leave an opening for the surgery.
  • Reusable sterilized cotton textile fabrics are one of the most common materials for this purpose.
  • Figure 1 shows four textile fabric sheets (1) ready to be placed on the patientt to give a square opening over the surgery area (4) the sheets are held to the skin of the patient with the tape (3).
  • Figure 2 shows a cross section on commonly used type of universal set made of double folded sheet of fabric (1) with a plastic film (2) placed between the sheets and a tape (3) that holds the sheet to the skin (5) of the patient,
  • This invention describes a solution to this problem and makes it possible for the first time to perform surgery with reusable fabric sheets without possibilityty for bacteria or body fluid penetration between the area of surgery and other parts of the patients skin.
  • Figure 3 shows one of the four sheets in a universal set made by the invention.
  • a rectangular opening (7) has been cut out.
  • the strip (8) shows a impregnated layer of fabric fastened on top of the sheet.
  • the strip (8) reduces the risk for the tape adhesive to penetrate into the sheet during the sterilization process and makes the tape stick to the sheet even when it is wet.
  • Figure 4 shows a cross section trough the rectangular opening on figure 3.
  • the plastic film (2) is placed between the sheets (1), a the tape (3) is fastened on the impregnated strip (8) and on the plastic film (2) and to the patients skin (5).
  • SUBSTITUTE SHEET This construction effectively restricts any transportation of body fluids from the surgery wound to the skin of the patient and forms a bacteria tight protection around the operation site.
  • the invention works the following way, figure 4, blood or body fluids from the surgery wound (6) are spread over the tape (3) to the sheet (1) were it is absorbed, the fluids can however not pass the trough the plastic film (2) and have no possibility to reach the skin of the patient since the tape (3) is sealed to the protective film (2) and to the skin of the patient (5).
  • This unique construction makes it possible for the first time to perform surgeryy with a bacteria and fluid tight area between the patients skin and the surgery site with reusable sets.
  • Figure 5 shows another type of operation set, so called single set, with an circular opening were two sheets (1) placed on top of each other with a plastic film placed between them (2) having a circular hole (9) cut trough booth the sheets and a smaller hole in the plastic film (10) placed in the center of the hole of the fabric sheets leaving a section of plastic film free to be taped to the skin of the patient, (4) is the surgery site.
  • the sheet area adjacent to the circular hole can also be impregnated to be impervious or have a impervious strip sawn or fastened on top of the sheet (11).
  • the set in figure 5 can be taped to the skin of the patient in the same way as described on the universal set and gives an absolute bacteria tight protectiveon between the patients skin and the surgery site.
  • Figure 6 shows a U set for special types of surgery around limbs etc. ,made of two sheets in the same way as the circular set on figure 5, leaving a small section of the plastic film (1) to stick out in the U shape, the U sheet is taped to the skin of the patient as described before.
  • the hole or opening in this so called single sets could be made in many shapes ea. oval, rectangular or square, suitable for the kind of surgery to be performed.
  • the dimension of the rectangular opening in the universal set can vary from 5 - 120 mm , preferably 20 - 100 mm.
  • the size of the hole in a hole drape can vary depending on the need for different type of operations from a diameter between 300 - 5 mm preferably
  • the size of the rectangular cut out in the universal sets can vary from a lengthh between 500 -30 mm preferably 50- 250 mm and a width between 5 - 300 mm preferably 10- 100 mm.
  • the shape of the cut can be rectangular, oval, square or any other shape suitable.
  • the protective sheet is normally some what smaller than the textile fabric sheetts but can be so small that it just about covers the opening cut in the fabric sheets.
  • the protective sheets is preferably made of a material resistant to sterilization either by steam, rays or ethylene oxide.
  • Material suitable could be e a PVC, HD or MD Polyethylene, Polypropylene films or of rubber sheets or reusable impervious or partly impervious fabrics like "Gortex", “Cambric” etc, or other well known fabrics for the persons skilled in the art.
  • the thickness of the films can vary from 0.005 mm to 0.250 mm, preferably 0.015 - 0.060 mm.
  • the impregnation of the edge around the opening in the sheets can be made with silicone, hot melts of different kinds, or other impregnations that holds the tape on the sheet when wet and prevent adhesive to penetrate into the sheet after sterilization, preferably silicone specially made to stick to fabric, these type of silicones are standard well known by the manufacturers of silicones and could be of one or two component types, with or without built in primers in order to improve sticking properties on textile fabrics.
  • an impregnated strip can be fastened around the edge of the opening in the sheets.
  • the width of the impregnated area or the strip can be anything from 5-100 mm preferably 5 - 50 mm, the length should be so it extends well beyond the rectangular opening in the universal sets and around the opening in the single sets.
  • the textile fabric sheets can be made of woven cotton fabric or synthetic materials such as polyester, polyamids or other suitable fibers or mixes thereof.
  • the sheets can also be made of different kind of non woven qualities, ea. polypropylene , polyester, or other man made fibers or mixes of natural fibers suitable for laundry and re use.
  • a commonly used textile sheet is a 100 % cotton fabric with a weight of between 200- 800 gr. /m2, these qualities are well known by persons skilled in the art.
  • the tape used in the sets can be of a conventional type used in these type of applications, well known by persons skilled in the art.
  • Figure 7 shows a not folded sheet in a universal set, with the rectangular cut
  • the protective film (2) is located so it covers half of the opening in the sheet.
  • the sheet is then folded so it leaves part of the plastic film sticking out in the rectangular opening in the sheet.
  • a tape (3) is then placed over the opening in the sheet so it covers the impregnated area of the sheet and the plastic film and sticks out beyond the plastic film, the free sticky area of the tape is then covered with a release paper on the back side.
  • the sheet can after this preparation be folded to a suitable form and packed for sterilization.
  • the dressing of the patient is made by removing the release paper from the tape on one of the sheets and press the tape so it sticks to the patients skin.

Abstract

Champs opératoires de protection réutilisables, composés de deux feuilles de tissu superposées, entre lesquelles est placé un film en matière plastique ou autre feuille imperméable. Les feuilles de tissus comprennent une découpe, réalisée dans le tissu, permettant à la feuille en matière plastique de dépasser du bord de la découpe, de sorte que le film aussi bien que la feuille puissent être fixés par ruban adhésif à la peau du patient afin que ni le sang ni les fluides biologiques ne puissent traverser la zone hermétiquement protégée.
