Definitions

  • the present invention falls within the technical field of devices for protecting wounds in the body of a patient.
  • the catheter must first be inserted through an adhesive dressing through a small hole, then fix the dressing on the skin exactly at the point of insertion of the catheter, then the catheter must be inserted into the colostomy bag, and finally the fix the colostomy bag to the dressing, all with a semi-rigid element such as the catheter exerting pressure and making the maneuver difficult.
  • a semi-rigid element such as the catheter exerting pressure and making the maneuver difficult.
  • the object of the present invention is to overcome the drawbacks of the state of the art by means of a device for protecting from moisture a wound configured to be capable of providing improved wound isolation, adequate protection and storage of eventual medical devices. existing in the wound or its proximity, as well as facilitating the monitoring of the state of the wound and even momentary access to it without the need to remove or discard the protection device, all this through greater ease of placement and use.
  • the device object of the invention comprises an elastomeric material to adapt to the body. It is a specific material called SEBS, and certified for medical use.
  • SEBS is a styrene-based block copolymer, in which the elastomeric phase is modified by hydrogenation.
  • SEBS belongs to the family of thermoplastic elastomers in which the elastic phase is made up of SEBS rubber (styrene-ethylene-butylene-styrene), and the plastic phase is generally made of an elastomeric polyolefin phase. Due to their structure and behavior, thermoplastic elastomers are located between plastics (thermoplastics) and rubber (elastomer). Thermoplastic SEBS combine the typical advantages of rubber and plastic materials. The products included in this class are compatible with polypropylene and are used for overmolding and extrusion. It has qualities of resistance to ultraviolet rays and weathering, with a high resistance to oxidizing agents.
  • the device object of the invention consists of at least two parts.
  • the first is a base with a floor element that comprises a flat horizontal extension provided with an adhesive surface on one of its faces, intended to contact with and be fixed to the patient's body.
  • Said adhesive has adhesion and permanence qualities that prevent accidental detachment of the patient's body, to which the material comprising the device contributes, whose ergonomic deformation and adaptability qualities guarantee that it adapts both to the different physiognomies and proportions of each patient and possible location point, such as the movements of said patient and superficial tensions or distensions of the patient's skin.
  • the first part of the device is placed on the patient's healthy skin around the wound.
  • the second part is a cover or cover element, to close an existing housing and interior space within the perimeter of the first base part and between the patient's skin and wound and the referred cover.
  • a perimeter vertical wall element is attached to either the first part or the second, in such a way that it determines a free interior space between the two parts of the device and the wound and the skin of the patient.
  • the internal housing of the device is wide enough to allow it to be positioned around the wound without touching it, and to contain a possible medical device that exists in or near the wound. At the same time, the simplicity of use is limited to fixing the base on the patient's body, and applying the cover on the base, placing a possible existing medical device on the wound in the internal housing.
  • the device is provided as a characteristic of the device that at least one of its parts is transparent, which makes it possible to monitor the condition of the wound and verify the maintenance of the hermetic and tightness of the internal housing of the device.
  • the present invention overcomes the drawbacks of the state of the art referred to above and provides an advantageous embodiment by means of an improved device in said aspects.
  • Figure 2 is another top perspective view of the device, and its two parts joined;
  • Figure 3 is a top perspective view and partially sectioned of the base part of the device
  • Figure 4 is an example of a wound in a patient with an implanted medical device of the peritoneal dialysis catheter type, and an example of embodiment and use of the device.
  • the device D for protecting a wound from the body of a patient object of the present invention from humidity comprises a base part 1 to be connected to the patient's body, and said base part 1 comprises, in turn, a flat floor element 1.1 to locate it around the wound of the patient's body; device D comprises a cover or cover element 2 for closing a space determining a housing 3 arranged between the base part 1 and the cover 2, and a wall element 4 arranged between the floor element 1.1 and the cover 2.
  • the wall element 4 forms a single part with the base part 1 or the wall element 4 forms a single part with the cover 2.
  • the floor element 1.1 comprises an adhesive surface on its face 1.11 of contact with the body of the patient.
  • At least the floor element 1.1 is made of an elastomeric material configured to adapt to the body of the patient.
  • the wall element 4 and the cover 2 are tongue and groove connectable, and the connection between the wall element 4 and the cover 2 is watertight .
  • the device D in one of its embodiments is made of a transparent material at least in some of its parts.
  • the wall element 4 comprises a wedge-shaped tongue 4.1.
  • the housing 3 of the device D is dimensioned to house a catheter C.
  • Device D is airtight.
  • the floor element 1.1, 1st cover 2 and / or the wall element 4 is made of a transparent elastomer material certified for medical use.
