Definitions

  • the present invention relates to a wound plaster or dressing that can be detected by X-rays
  • plasters that can be detected automatically.
  • the person involved may drop the plaster into the food products that are being prepared. It is, of course, vital that such food products do not reach a consumer, who would in this case discover a plaster in the food. It is also of the highest importance that infection is not spread with the food products due to someone having dropped a plaster into food products that are being prepared.
  • an X-ray machine is arranged along, for example, a transport belt for food prod- ucts.
  • the X-ray machine is of continuous type, i.e. it emits X-rays of either continuous or pulsating type.
  • a plaster that can be detected by X-rays has been revealed in European patent number 0768855.
  • the plaster has been loaded for this purpose with the material tungsten.
  • Tungsten is a very hard material, and it is therefore difficult to fashion it to a form that is suitable to be used in a plaster.
  • tungsten has been shown to have certain health effects such as irritation of the skin on contact. It is recommended that protective equipment be used when handling tungsten in industrial processing. It is therefore a desire to avoid the use of tungsten.
  • the present invention solves this problem.
  • the present invention thus relates to an X-ray detectable plaster or dressing and is characterised in that the plaster or dressing comprises a material with at least 80% by weight tantalum, in that the material comprises up to, but lower than 10% by weight tungsten, and in that the material has a volume of at least approximately 0.1 mm 3 .
  • FIG. 2 shows a side view of a plaster.
  • the present invention is described below with reference to a plaster, but the invention is not limited to plasters in the general sense of the term, but can be used in the same way for other dressings such as, for example, compresses, surgical tape, etc.
  • Figure 1 shows an X-ray detectable plaster 1, comprising a support 2 provided with an adhesive and a wound pad 3.
  • the plaster itself is a conventional plaster.
  • the plaster 1 comprises a material with at least 80% by weight tantalum, with a volume of at least 0.1 mm 3 . Furthermore, the material comprises tungsten up to, but lower than 10% by weight. The remaining material, which may be up to 10% by weight, is a material that is suitable for the present applications, and it may be chosen by one skilled in the art.
  • the plaster 1 comprises a material with at least 90% by weight tantalum and up to, but lower than 10% by weight tungsten, where the material has a volume of at least 0.125 mm 3 .
  • the X-ray detectable material in the drawings is a thread 4.
  • tantalum has a much lower density than tungsten.
  • the ductility of tantalum is relatively high, and it is therefore easy to process to form a foil or thread.
  • tantalum does not give rise to any negative effects on humans.
  • tantalum is spontaneously covered by a protective layer of oxide, which leads to a very high resistance of tantalum to, among other agents, acids, most salt solutions and organic chemicals, and this is a positive property with respect to the production of foods.
  • the said material may have any suitable form, but according to a first preferred embodiment the said material has the form of a foil with a minimum length of about 5 mm, a minimum width of about 1 mm and a minimum thickness of about 25 micrometres . According to a second preferred embodiment, the said material is in the form of a thread with a diameter of at least about 30 micrometres and a length that gives a volume of at least about 0.1 mm 3 .
  • Tantalum metal can be obtained both as foil and as thread.
  • a plaster 1 comprising a support provided with an adhesive and a wound pad 3
  • the said material independently of its form, be placed between the support and the wound pad, or alternatively in the support, or in the wound pad.
  • the said material be located within the compress .
  • the said material is in the form of a powder.
  • the powder may in this case be applied to the said support by adhesive.
