  • the tearing of the skin when removing bandage is given as a specific example of a skin tear.
  • Such medical device related pressure ulcers and skin tears are more likely to occur in patients with skin problems such as patients with skin diseases, infants, and the elderly.
  • these pressure ulcers and skin tears are particularly likely to occur when a highly adhesive skin adhesive tape is used.
  • a highly adhesive skin adhesive tape is used.
  • tape is affixed to the skin of a patient with weak skin such as with ventilator tracheal tubes, indwelling vascular catheters, urethral catheters, nasogastric tubes, or transnasal oxygen cannulas.
  • a relatively adhesive skin adhesive tape is selected so that the tape does not come off.
  • catheters for indwelling urethral catheters, nasogastric tubes, and transnasal oxygen cannulas need to be replaced regularly in order to be cleaned.
  • peeling off the adhesive tape from the patient's skin is necessary.
  • the adhesive tape exerts a strong force on the skin of the patient.
  • the skin of the patient is weak, when the adhesive tape is peeled off, a wound may be generated at the site to which a strong force is applied.

  • Non-Patent Document 1 a for avoiding applying a strong force to the skin while maintaining the adhesion of the adhesive tape, a method in which an intermediate layer is provided between the adhesive layer of the adhesive tape and the base layer to facilitate the separation of the two is known.
  • this method when the adhesive tape is peeled off, the adhesive layer and the base layer peel in the intermediate layer. Therefore, only the base layer can be removed while leaving the adhesive layer on the adhesive surface. Then, while maintaining the adhesive strength of the adhesive tape, avoiding applying a strong force to the object when peeling off the base layer becomes possible.
  • the use of such an intermediate layer approach to medical tape reduces the risk of skin wounds occurring when the tape is removed when peeling off the tape.
  • the adhesive layer remains on the skin.
  • the adhesive layer left on the skin then is able to irritate the skin.
  • leaving the adhesive layer for a long time on the skin of a patient susceptible to irritation is not possible.
  • the adhesive layer also needs to be removed at an early stage from the patient's skin. Then, when peeling off the adhesive layer a strong force is applied to the skin. In the end, there is a risk of skin damage.
  • a method in which a solvent is applied to an adhesive tape just before peeling off a bandage to weaken the adhesive force and then peeling off adhesive tape in order to reduce the occurrence of a wound is known.
  • the solvent remains on the skin after treatment. Then, if the adhesive tape is refixed in that state, there is a problem that the adhesive strength of the refixed adhesive tape fails.
  • the waterproof tape the solvent does not get into the tape member, and there is a problem which takes time and effort in order to peel off the tape in that it is necessary to peel off the member a little and squeeze the solvent while directly impregnating it between the adhesive layer and the skin.
  • the adhesiveness of the bandage is weakened to protect the stratum corneum of the skin so that peeling off of the stratum corneum does not occur when the bandage is peeled off has been considered.
  • expanding the area being stuck to the skin is necessary.
  • increasing the application area of the bandage increases the possibility that the bandage will be applied to a portion where the cutaneous layer (skin) and subcutaneous tissue (hypodermis) are weakly connected, or to a portion originally having a wound on the epidermis.
  • the conventional (silicon-based) bandage with a weakened adhesiveness in order to protect the stratum corneum needs to have a large application area to strengthen the adhesiveness, and in this case, even if the patient's stratum corneum can be protected, there was also the problem that the skin cannot always be prevented from being damaged from peeling off from the subcutaneous tissue.
  • an object of the present invention is to make it easy to peel off the adhesive tape while maintaining the adhesion of the adhesive tape to the skin, and to prevent a wound from being generated on the skin when the adhesive tape is peeled off. More specifically, the present invention is aimed at preventing damage caused by skin peeling off from subcutaneous tissue.
  • the inventors of the present invention found that wounds can be prevented from occurring in the peeled portion of a tape member by providing a mesh member on an adhesive side of a tape member, which during adhesion, the adhesive surface adheres to the skin of the patient through the openings of the mesh member, and during peeling, the tape member is peeled while holding the mesh member against the skin surface. Then, the present inventors considered that the problems of the prior art could be solved based on the above findings, and completed the present invention. Specifically, the present invention has the following configuration.
  • the present invention relates to a tape product 100 adhered to an object, such as a patient's skin.

  • the adhesive surface of the tape member 10 adheres to the skin through the openings 21 in the mesh member 20 at the time of bonding, so that the adhesive strength of the entire tape product 100 can be maintained.
  • the tape member 10 is pulled in the opposite direction.
  • the pulling force of the tape member 10 is relaxed or offset by the pressing force of the mesh member 20 .
  • the tape product 100 is attached to the surface of hairy skin, since the mesh member 20 acts to press down the hair, Preventing the hair from coming off when the tape member 10 is peeled off is possible. As a result, the tape member 10 can be peeled off with little pain to the patient.
  • sufficient adhesion can be obtained without covering a wide application area, so that preventing the skin from being peeled off from the subcutaneous tissue is possible.
  • the tape member 10 has a base layer 11 and an adhesive layer 12 laminated on the base layer 11 which constitutes an adhesive surface.
  • the adhesive layer 12 is formed of a gel-like adhesive, and the gel-like adhesive layer 12 may be deformed and exuded from the openings 21 in the mesh member 20 .
  • Gel generally refers to dispersed materials that have high viscosity and lost flowability.
  • the gel adhesive layer 12 exudes from the gaps (openings 21 ) of the mesh member 20 and adheres to the skin. Thereby, the adhesiveness of the tape member 10 becomes large.

  • the base layer 11 is formed of, for example, a stretchable material such as a non-woven fabric. Then, when the tape product 100 is pressure-bonded to the skin, the stretchable base layer 11 stretches, and the stretchable adhesive layer 12 adheres to the skin through the openings 21 in the mesh member 20 . Thereby, the adhesive force of the tape member 10 becomes large. Therefore, even if the mesh member 20 is interposed between the tape member 10 and the skin, the tape product 100 can be used to maintain sufficient cohesion to secure medical tubing or needles.
