Abstract

The utility model discloses a wet dual-purpose medical dressing futilely, comprises a substrate, the unit is pasted in a plurality of turns to the coating on the substrate, paste the unit in turn including the dry viscidity rubber coating region that sets gradually, non-rubber coating region and wet viscidity rubber coating region, the coating has medical pressure sensitive adhesive on the dry viscidity rubber coating region, the coating has wet viscidity medical adhesive on the wet viscidity rubber coating region, paste the unit in turn and keep away from one side of substrate is equipped with from the type layer. In the actual use process of the dry and wet dual-purpose medical dressing, the medical pressure-sensitive adhesive generally plays a main sticking role, so that the medical dressing has good sticking property and does not fall off; when the skin sweats, the wet viscous medical adhesive plays a main sticking role, prevents the dressing from falling off, and simultaneously is matched with the good moisture permeability of the non-glued area reserved on the base material by alternately gluing, thereby improving the overall sticking performance of the medical dressing.

Description

Dry-wet dual-purpose medical dressing

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to wet or dry medical dressing.

Background

Medical dressings are generally composed of release paper, an adhesive, a Polyurethane (PU) film or a Thermoplastic Polyurethane (TPU) film or other base materials, and are made by uniformly coating an adhesive such as a pressure-sensitive adhesive on one side of a base material. Although adhesion performance is good under the general condition in the in-service use process at present most dressings, still can appear adhesion performance decline when skin perspires, easily stick up the limit and even the phenomenon that drops, this is mainly because when the mode of substrate is evenly coated to the adhesive on the dressing, most can not see through the glue film and volatilize after the sweat is concentrated, can only exist between skin surface and the glue film to influence the whole effect of pasting of dressing, also influence patient's use comfort.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a technical scheme does:

the utility model provides a wet or dry medical dressing, includes the substrate, it pastes the unit to have coated a plurality of in turn on the substrate, paste the unit in turn and including the dry viscidity rubber coating region that sets gradually, non-rubber coating region and wet viscidity rubber coating region, it has medical pressure sensitive adhesive to have coated on the dry viscidity rubber coating region, the regional medical adhesive that has coated of wet viscidity rubber coating, paste the unit in turn and keep away from one side of substrate is equipped with from the type layer.

The utility model discloses further set up to the dry viscidity rubber coating is regional non-rubber coating region with the regional mutual parallel arrangement of wet viscidity rubber coating. The dry viscous gluing area, the non-gluing area and the wet viscous gluing area which are parallel to each other are convenient for processing in actual production.

The utility model discloses further set up as what medical pressure sensitive adhesive adopted is polyisobutylene pressure sensitive adhesive, polyacrylate pressure sensitive adhesive or silicone pressure sensitive adhesive.

The utility model discloses further set up as what medical adhesive of wet viscidity adopted is acrylic acid modified starch glue.

The utility model discloses further set up as what the substrate adopted is polyurethane membrane or thermoplastic polyurethane membrane.

The utility model discloses further set up as the width ratio of dry viscidity rubber coating region, non-rubber coating region and wet viscidity rubber coating region is 1.5:1: 1. The dressing with the width ratio of the dry adhesive gluing area to the non-adhesive gluing area to the wet adhesive gluing area being 1.5:1:1 has a more prominent practical sticking effect.

The utility model discloses further set up as what adopt from the type layer is from the type membrane or from type paper.

The utility model discloses further set up as the shape of substrate is oval, circular or rectangle.

The utility model discloses further set up to be equal to or be greater than from the area on type layer the area of substrate.

The utility model discloses further set up to be equipped with the tear tape from the both sides on type layer. The tearing strip is convenient for peeling off the parting layer when the dry-wet dual-purpose medical dressing is used.

Adopt the technical scheme provided by the utility model, compare with prior art, have following beneficial effect:

the medical dressing for dry and wet dual purposes is prepared by alternately coating medical pressure-sensitive adhesive and wet adhesive on a Polyurethane (PU) film or Thermoplastic Polyurethane (TPU) film or other base materials with good moisture permeability, and leaving a non-adhesive area with a certain width between the PU film and the TPU film, so that the area can ensure the moisture permeability to a certain degree. In the actual use process, the medical pressure-sensitive adhesive generally plays a main sticking role, so that the medical dressing has good sticking performance and does not fall off; when the skin sweats, the wet viscous medical adhesive plays a main sticking role, prevents the dressing from falling off, and can improve the overall sticking performance of the medical dressing by matching with the good moisture permeability of the non-glued area reserved on the base material by alternately gluing.

The utility model discloses wet or dry medical dressing homoenergetic has better whole effect of pasting when dry or when perspiring, makes patient have better use and experiences and comfort.

Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples.

Combine accompanying drawing 1-2, the utility model discloses technical scheme is a wet or dry medical dressing, including substrate 1, the coating has a plurality of unit 2 of pasting in turn on the substrate 1, paste unit 2 in turn including the regional 21 of dry viscidity rubber coating that sets gradually, regional 22 of non-rubber coating and the regional 23 of wet viscidity rubber coating, dry viscidity rubber coating is regional 21 non-rubber coating region 22 with the regional 23 parallel arrangement each other of wet viscidity rubber coating, the coating has medical pressure sensitive adhesive on the regional 21 of dry viscidity rubber coating, the coating has wet viscidity medical adhesive on the regional 23 of wet viscidity rubber coating, paste unit 2 in turn and keep away from one side of substrate 1 is equipped with from type layer 3.

The medical pressure-sensitive adhesive adopts polyisobutylene pressure-sensitive adhesive, polyacrylate pressure-sensitive adhesive or silicone pressure-sensitive adhesive, and preferably adopts polyacrylate pressure-sensitive adhesive.

The wet-stick medical adhesive is preferably an acrylic modified starch adhesive.
