Definitions

  • the invention relates to a protective device comprising a container part formed by a water impermeable material and tubular fixation device formed by an elastic water impermeable material.
  • the invention further relates to a method for removing a protective device from a limb and use of a protective device. Background of the invention
  • the invention provides for a protective device comprising a container part formed by a water impermeable material, wherein the container part includes at least one container opening.
  • the protective device further comprises a tubular fixation device formed by an elastic and water impermeable material, wherein a first end of the fixation device is connected to the container part at the container opening and wherein a second end of the fixation device comprises an edge portion encircling a protective device opening enabling access through the tubular fixation device and into the container part.
  • the tubular fixation device comprises at least one tear zone arranged at the edge portion.
  • Arranging a tear zone at the edge portion of the elastic tubular fixation device is advantageous in that it hereby is possible remove the protective device from a limb after use in a simple and convenient manner in that the tear zone enables that the elastic tubular fixation device may be torn to break its elastic hold on the limb - thus making it easy to remove the protective device without affecting sore areas of the limb.
  • arranging the tear zone at the at the edge portion encircling the protective device opening is advantageous in that it is easier and more convenient to start the tear at the edge and ensure that it propagates through the tubular fixation device to cancel out its fixating and sealing effect.
  • locating the tear zone at the at the edge portion is advantageous in that it hereby is possible to prevent the tear zone from starting a tear at an unwanted time. This can be done by rolling up at least a part of the second end of the fixation device to enclose the tear zone inside this rolled up end - e.g. during application on a limb and during use - so that after use the rolled up end may be unrolled to expose the tear zone and make it easy to initiate the tear at the tear zone.
  • elastic ... matericiF any kind material capable of a high degree of elastic deformation under stress and still capable of returning to its previous size without permanent deformation.
  • Such materials are characterised by a low Young's modulus i.e. typically below 2 giga-Pascal (GPa), and preferably below 1 giga-Pascal.
  • GPa giga-Pascal
  • Such materials include many types of natural or synthetic rubber materials, such as latex, nitrile rubber, butyl rubber, silicone rubber or other.
  • tear zone in this context is to be understood any kind of local area prone to tear. I.e. the areawise confined tear zone is different from the remaining edge portion in that if the edge portion is stressed - e.g. by manually pulling the edge portion - the edge portion will start to tear in the tear zone and the tear will propagate from the tear zone, into the edge portion and further through the tubular fixation device.
  • the at least one tear zone has a reduced tensile strength in relation to the remaining material at the edge portion.
  • the edge portion comprises an elastic ring formed by or connected to the tubular fixation device.
  • Providing an elastic ring at the edge portion is advantageous in that it makes it easier to manually get hold of the edge portion and to control the sealing effect of the elastic tubular fixation device.
  • the tear zone comprises a part of the ring having a reduced cross sectional diameter.
  • the tear zone is formed by a hack in the edge portion.
  • Removing a small amount of material at the edge portion or cutting the edge porting to form a hack - i.e. a notch, an indentation, a nick, a cut or the like - is a simple and inexpensive way of forming a defined tear zone.
  • the area of the container opening is larger than the area of the protective device opening.
  • the elastic tubular fixation device fits snugly around the limb on which it is placed to form a tight seal between the protective device and the limb. It is also advantageous that the container part does not press against the limb or a dressing or a bandage on the limb to reduce discomfort. I.e. it is advantageous to form the diameter of the tubular fixation device smaller than the diameter of the container part. Thus, it is advantageous to increase the diameter of the tubular fixation device from the protective device opening towards the container opening to enable a smooth transition between the two. Another way of putting it would be that in an aspect of the invention, the first end diameter of the fixation device at the first end is larger than the second end diameter of the fixation device at the second end. In an aspect of the invention, the container part and/or the tubular fixation device is formed by a transparent material.
  • the container part and the tubular fixation device are formed integrally. Forming the container part and the tubular fixation device integrally from the same piece of material is advantageous in that it simplifies the manufacturing process and logistics.
  • the container part and the tubular fixation device are formed as two separate parts being connected by permanent connection means.
  • Forming the container part and the tubular fixation device as two individual parts is advantageous in that it hereby is possible to form the two parts from different materials having different characteristic.
  • the term "permanent connection means” is to be understood any kind of connector capable of permanently connecting a container part to a tubular fixation device - i.e. any kind of adhesive, welding, soldering, riveting or other.
  • the container part is formed as a bag. Forming the container part as a bag - i.e. with only a single opening in the form of the container opening - is advantageous in that it hereby is possible to make the protective device completely enclose the limb on which it is mounted and thereby efficiently protect the covered limb from getting wet.
  • the tubular fixation device is rolled up to encircle the at least one tear zone.
  • the tubular fixation device comprises flap means.
  • Providing the tubular fixation device with flap means is advantageous in that the flap means are easy to grip and get a hold of even though the tubular fixation device tightly encircles the limp on which it is mounted.
  • the flap means is arranged adjacent to the at least one tear zone.
  • Arranging the flap means right beside the at least one tear zone is advantageous in that the flap means hereby will aid in tearing the tubular fixation device when pulled.
  • the flap means are formed integrally with the edge portion. Forming the flap means integrally with the edge portion is advantageous in that it ensures a simple manufacturing process, and in that the flap means and the edge portion will form a strong connection. In an aspect of the invention, the flap means are formed as a separate part in relation to the edge portion.
  • Forming the flap means in a material separate from the material of the edge portion is advantageous in that the flap means hereby more easily can be formed in a material more suited for forming flap means. I.e. this design enables that the flap means can be formed in a stronger and/or less elastic material.
  • the flap means are longer than the axial extend of the tubular fixation device.
  • Forming the flap means are longer than the axial extend of the tubular fixation device is advantageous in that it hereby is ensured that when the tubular fixation device is rolled up to protect the tear zone, the flap means will still extend from the rolled up part and ensure more efficient unrolling, ensure that the tear zone is more easily identified and/or ensure that the unrolling and tearing process can happen substantially continuously in a single process since the flap means is attached at the tear zone.
  • the tubular fixation device is made from a natural or synthetic rubber material.
  • the tubular fixation device is advantageous in that these materials are relatively cheap and elastically. Furthermore, the friction between the layers in the rolled up tubular fixation device will be very high when the tubular fixation device is made from natural or synthetic rubber material, thus ensuring that the tear zone is well protected inside the rolled up part.
  • the tubular fixation device is made from a material prone to tear in one direction.
  • Forming the tubular fixation device in a material prone to tear in one direction so that the tubular fixation device is prone to tear in the axial direction of the tubular fixation device is advantageous in that the risk of the tubular fixation device breaking while expanded during the mounting process is reduced while the subsequent tearing process is more efficient.
  • the ability of tearing more easily in one direction than the other can be achieved by pre- stretching the material in one direction during the manufacturing process or in other ways forming the molecular structure of the material so that the mutual bonds are e.g. stronger lengthwise than laterally.
  • the invention provides for a method for removing a protective device from a limb.
  • the method comprises the steps of:
  • Arranging the tear zone inside a rolled up end of the protective device is advantageous in that the even if the rolled up end is stretched, the tear zone will not initiate a tear in the protective device. However, as soon as the rolled up end is unrolled and the tear zone is exposed only a slight pull in the protective device at the tear zone will initiate propagation of a tear which will break the seal at thus loosen the protective device from the limb and make it easy to remove the protective device.
  • the tear zone is protected inside the rolled up end until the rolled up end is unrolled.
  • the protective device is torn by manually pulling the protective device at the exposed tear zone.
  • Tearing the protective device apart by manually pulling the protective device at the exposed tear zone is advantageous in that it hereby is possible for the user to easily remove the protective device after use without requiring further assistance.
  • the unrolling of the rolled up end is at least aided by pulling one or more flap means, having one end extending from the rolled up end and another end being attached to the protective device at the tear zone.
  • Aiding the unrolling by pulling flap means - being attached at the tear zone and being rolled up with the rolled up end - is advantageous in that it ensures a more efficient unrolling, in that the tear zone is more easily identified and/or in that the unrolling and tearing process can happen substantially continuously in a single process since the flap means is attached at the tear zone.
  • the method is a method for removing a protective device according to any of the previously mentioned protective devices.
  • the invention also provides for use of a protective device according to any of the previously mentioned protective devices for protecting a bandage, a plaster or similar on a limb from becoming wet.
  • a bandage, a dressing, a plaster or similar is typically applied in relation with wounds, fractures or other injuries and in this relation it is therefore advantageous to use a protective device according to the present invention since this protective device easily can be removed without affecting the injuries.

  • the tubular fixation device 4 is made from a highly elastic rubber material enabling that the rolled up end 13 of the protective device 1 - i.e. the second end 6 of the tubular fixation device 4 - and the rest of the tubular fixation device 4 can be stretched to a larger diameter - e.g. by another person assisting the user - during application on a limb 12, so that the protective device 1 may be mounted on a limb 12 substantially without the tubular fixation device 4 touching the injured area on the limb 12.
  • the elastic quality of the tubular fixation device 4 ensures that when the tubular fixation device 4 has passed the area to be protected and the rolled up end 13 of the protective device 1 is released, the tubular fixation device 4 will retract to its original diameter and form a tight seal against the limb 12.
