Description

PU type elastic adhesive plaster

Technical Field

The utility model relates to the field of medical supplies, especially an elastic adhesive plaster on ostomy bag chassis.

Background

The commonly adopted product for fixing the base plate of the ostomy bag in the market is an elastic adhesive tape which is used for fixing the base plate of the ostomy bag and preventing the edge from being warped. The elastic adhesive plaster in the market is mostly arc-shaped and is made of hydrocolloid serving as a raw material. Because the elastic adhesive sticker is a disposable article and is usually scrapped together after the ostomy base plate is replaced, the hydrocolloid which is the same as the base plate is used as the raw material, the production process is complex, the cost is high, the price is high, and a large economic burden is caused to a user; market needs a product can replace current elasticity to glue and pastes, can play the chassis that prevents equally and stick up the limit, consolidates the elasticity of the effect on chassis and glues and paste, the utility model provides a such problem.

SUMMERY OF THE UTILITY MODEL

For solving prior art's not enough, the utility model aims to provide a PU type elasticity is glued and is pasted for the pocket chassis is made in the fixed, and frivolous close skin improves the comfort, and is with low costs.

In order to achieve the above object, the utility model adopts the following technical scheme:

PU type elasticity is glued and is pasted, includes: the PU resin layer, form in the viscose layer of PU resin layer one side, set up in the type paper that leaves under the viscose layer, set up in the PET of PU resin layer opposite side from the type membrane, set up in the sign strip that PET left the open position of type membrane.

The PU type elastic adhesive sticker is arranged in a manner that the opening position of the release paper and the opening position of the PET release film are staggered.

In the PU-type elastic adhesive tape, the opening of the release paper is located on the side, and the opening of the PET release film is located in the middle.

In the PU-type elastic adhesive tape, the opening of the release paper is an S-shaped opening.

In the PU-type elastic adhesive tape, the opening of the PET release film is an S-shaped opening.

In the PU type elastic sticker, the identification strip is a colored PE strip.

In the PU type elastic adhesive tape, the thickness of the PU resin layer is less than 0.1 mm.

The utility model discloses an useful part lies in:

the utility model discloses a PU resin layer replaces hydrocolloid, plays the chassis of preventing equally and sticks up the limit, consolidates the effect on chassis, and PU resin layer and the PU resin raw materials and the solvent adhesive of my department that the viscose layer adopted, and each item performance detects all has strong evidence and guarantee.

The thickness of the PU resin layer is less than 0.1mm, and the PU resin layer is light, thin and skin-friendly, so that discomfort of a user is reduced.

The product of the utility model is simple in structure, only relate to rubber coating and compound in the technology, easily put in production, the appearance adopts and pastes the same arc with the current elasticity is glued, can be used to make most of products on pocket chassis on the market.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a top view of an embodiment of the present invention;

fig. 3 is a bottom view of an embodiment of the present invention.

The meaning of the reference symbols in the figures:

1PU resin layer, 2 viscose layers, 3 from type paper, 301 from the opening of type paper, 4 PET from type membrane, 401 PET from the opening of type membrane, 5 sign strips.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the PU type elastic sticker includes: PU resin layer 1, the viscose layer 2 that forms in PU resin layer 1 one side sets up in viscose layer 2 down from type paper 3, sets up in the PET of PU resin layer 1 opposite side from type membrane 4, sets up in the sign strip 5 that PET left type membrane's opening 401 position. The PU resin layer 1 is made of polyurethane resin; the adhesive layer 2 is made of solvent-based pressure-sensitive adhesive of 2-ethylhexyl acrylate and ethyl acetate; this substrate is marketed as a transparent applicator, transparent dressing roll, which companies are producing.

In order to facilitate the user's recognition of the position of the tear film, the identification strip 5 is preferably a colored PE strip, as shown in fig. 1.

As shown in fig. 2 and 3, the position of the opening 301 of the release paper is staggered with the position of the opening 401 of the PET release film; as an example, the opening 301 of the release paper is located at the side edge, and the opening 401 of the PET release film is located at the middle.

Preferably, as shown in fig. 2 and 3, the opening 301 of the release paper is an S-shaped opening, and the opening 401 of the PET release film is an S-shaped opening, so that the film can be easily torn by a user.

The thickness of PU resin layer 1 is less than 0.1mm, and ultra-thin thickness is favorable to laminating skin fixed rubber dish, and the user can not feel to be pasted this product, and the waterproof ventilative characteristic of PU material lets use more comfortablely.

The production process of the utility model is as follows:

1, coating PU resin on a heavy-stripped PET release film 4, and coiling;

2, coating solvent glue on the light-stripped PET release film 4, and coiling;

3, compounding and cutting the two coiled materials into small rolls;

4, attaching a colored PE strip and release paper 3 on the small roll, and performing S-shaped die cutting;

and 5, punching into a circular arc shape to obtain the PU type elastic adhesive plaster.

The utility model discloses a use method does:

1, firstly tearing off half of the release paper 3, and fixing the release paper at a proper position of the rubber plate to ensure that the elastic adhesive sticker is fixed on the skin along the edge of the chassis.

2, tearing off the other half of the release paper 3 and attaching the release paper to the skin.

And 3, tearing the PET release film on the upper layer according to the S cutting edge on the colored PE strip.

The utility model adopts the PU resin layer 1 to replace hydrocolloid, which also plays the roles of preventing the chassis from edge warping and reinforcing the chassis, and the thickness of the PU resin layer 1 is less than 0.1mm, thus being light and thin and being skin-friendly and reducing the discomfort of users; the PU material has waterproof and breathable characteristics, so that the use is more comfortable. The utility model discloses simple process easily puts in production, and the appearance adopts and pastes the same arc with the current elasticity, can be used to make most of products on pocket chassis on the market.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
