Description

[Detailed Description of the Invention] (Industrial field of application) The present invention specifies a pad such as gauze applied to the wound for the purpose of protection and treatment, a patch containing a medicinal component to be applied to the skin, etc. The present invention relates to a pressure-sensitive adhesive sheet for medical assistance for fixing in position.

(Prior art) Conventionally, for fixing pads such as gauze applied to a wound part and patches applied to the skin, a long and narrow tape-shaped adhesive plaster is applied to the cross, cross, etc. A method of sticking them on one another and a method of sticking and fixing with a single adhesive sheet larger than the fixing object such as pads and patches have been adopted.

(Problems to be solved by the invention) However, in the case of sticking and fixing with the adhesive bandage, when the number is small or the length is not sufficient, it is difficult to sufficiently fix the fixed target object at the target position,
It was easy to peel off. Also, when the number of plasters is increased to ensure fixation and each is made to have a sufficient length, the central part with the fixing object rises up and the surrounding skin feels firm and the appearance and usability are satisfactory. It wasn't possible.

Furthermore, when using such a long bandage, a long skin area for sticking the bandage around the fixed object is required, and when such a skin area cannot be secured, in the first place, such a long bandage It was difficult or impossible to use.

Also, when using a single adhesive sheet, when the thickness of the fixed object is large, there is no three-dimensional margin to cover it and stick it to the skin, so wrinkles occur around the adhesive sheet, and the appearance However, there was a problem that the sticking feeling was both reduced.

In order to solve such a problem, there was also one in which the base material of the pressure-sensitive adhesive sheet was composed of a flexible plastic sheet, but in that case, since the air permeability was poor, the applied skin became stuffy, and rashes and itchiness occurred. Was the cause of.

Then, this invention aims at providing the adhesive sheet for medical assistance which eliminates the problem of the said conventional plaster and adhesive sheet.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an adhesive sheet body including a backing support and an adhesive layer laminated on one side of the support, and an adhesive surface of the body. The adhesive sheet main body is provided with a plurality of first incision cut lines that do not reach the peripheral edge from the central portion to the peripheral portion, and the peelable protective sheet is laminated. A second cutting line for incision is provided on the property protection sheet at a position corresponding to the first cutting line, and a third hem connecting the hem of the second cutting line is provided.
The present invention provides a pressure-sensitive adhesive sheet for medical assistance, wherein the incision score line is provided.

The incision score line provided on each of the pressure-sensitive adhesive sheet body and the peelable protection sheet may be provided continuously or intermittently in a one-dot chain line shape, a broken line shape, or the like. In short, it may be in a state where it can be easily incised manually.

Further, the score lines extending from the central portion of the pressure-sensitive adhesive sheet body and the central portion of the peelable protective sheet may or may not be connected to each other at the central portion. In short, it is sufficient if it can be easily opened manually.

The third score line connecting the bottoms of the score lines extending from the central portion to the peripheral portion provided on the peelable protective sheet may be an intermittent score line, but is preferably a continuous score line.

Each score line may be a straight line, a curved line, or a combination thereof.

(Operation) According to the pressure-sensitive adhesive sheet for medical assistance of the present invention, the peelable protective sheet covering the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet main body is peeled off except for a portion of the sheet surrounded by the third score line. Then, the part where the release sheet still remains is incised by the first and second incision lines and the incised part is applied to human skin,
The exposed adhesive surface, which is applied from above a fixed object such as a patch and which appears by removing a part of the peelable protective sheet, is stuck to the skin around the fixed object.

After that, the protective sheet portions separated by the second score line are individually peeled off from the adhesive surface,
Thus, the exposed adhesive surface is attached to the fixed object and also to the skin if there is room. Thus, the fixed object is fixed in position.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 7 show an embodiment of the present invention.

FIG. 1 is a plan view of an adhesive sheet for medical assistance, and FIG.
FIG. 3 shows a cross section taken along the line XX ′ in the drawing, and FIG. 3 shows the bottom surface.

As can be seen from these figures, in this medical-adhesive sheet, the adhesive layer adhesive surface of the adhesive sheet body 10 obtained by laminating the adhesive layer 2 on the backing support 1 is covered with the peelable protective sheet 3. It is a thing.

As shown in FIG. 1, the main body 10 is provided with five intermittent cutting lines T for cutting in a straight line from the central portion toward the vicinity of the periphery. Each score line T does not reach the peripheral edge of the main body 10 but stops before it. Therefore, the body
10 is a state in which the peripheral portion 10a is connected in a ring shape, and can be cut into five portions.

On the other hand, as shown in FIG.
Five intermittent cut lines P1 are provided from the central portion. These cut lines P1 are aligned with the cut line T and overlap the cut line T.

The bottom end of the score line P1 is connected by a continuous score line P2.

Thus, the protective sheet 3 has a portion S2 surrounded by a continuous cut line P2 (the lower right hatched portion in FIG. 3), and its peripheral portion.
S1 (the upper right hatched portion in FIG. 3) can be peeled off from the main body 10 independently.

The procedure for using the embodiment shown in FIGS. 1 to 3 will be described with reference to FIGS. 4 to 7. First, the protective sheet 3 will be described.
Of this, the outer peripheral portion S1 is peeled off except for the portion S2 surrounded by the score line P2, and as shown in FIGS. 4 and 5, the peripheral portion A of the adhesive surface is exposed. .

Next, the part S2 of the peelable protective sheet 3 and the part of the adhesive sheet body 10 that overlaps with this are cut into five triangular parts 100 by the cut lines P1 and T. The part 100 is the sixth
As shown in the figure, it is applied to the fixing object G on the human skin D, and the adhesive surface peripheral portion A is attached to the skin D. In this state, the protective sheet portion 3 ′ is peeled off from each triangular portion 100, and the adhesive surface 2 ′ thus exposed is attached to the skin D and the fixing target G.

Thus, as shown in FIG. 7, the fixed object G is reliably and stably fixed at a predetermined position.

According to the above-described embodiment, the adhesive sheet body 10 has the fixed object G.
Adhere to the fixed object G with sufficient margin without making a strong pulling force on each of the triangularly opened parts 100, while making good use of the not-so-wide part around the part and securely adhering to the part. Therefore, there is no feeling of tension during use, and yet the fixing target object is stably and reliably fixed to a predetermined position. In addition, since the adhesive sheet is not overlaid on the fixed target object G and several sheets of the adhesive object are not covered, the appearance is neat.

Next, the embodiment shown in FIGS. 8 and 9 will be described.

In this embodiment, the adhesive sheet body 10 is formed in a rectangular shape, and the peelable protective sheet 3 covering the adhesive surface of the sheet body 10 is also formed in a rectangular shape. Seat body 10
In total, eight incision cutting lines T are formed intermittently from the central portion to the vicinity thereof.

Further, as shown in FIG. 9, the protective sheet 3 is formed with a continuous cut line P1 at a position corresponding to the cut line T, and the whole cutout line P1 is formed so as to connect the hem portion thereof. A continuous cut line P2 is formed in a rectangular shape.

In the case of this embodiment, in use, the portion S2 (the lower right diagonal line portion) of the protective sheet 3 surrounded by the score line P2 is left, and the surrounding portion S1 (the upper right diagonal line portion) is first peeled off,
The exposed adhesive surface is attached to the periphery of the fixed object G, and the rest is processed in the same manner as in the above-mentioned embodiment. In the case of this embodiment, the score line T of the pressure sensitive adhesive sheet body 10 may be entirely cut,
For example, a total of four pieces may be cut open every other piece, and the rest may be left uncut. In the case of the embodiment shown in FIG. 1 to FIG. 7 as well, it is not necessary that all the cut lines T of the adhesive sheet body 10 be cut, and they may be cut partially.

Adhesive sheet body 10 and releasable protective sheet 3 covering it
The shape is not limited to a circular shape or a rectangular shape as in the above-described embodiments, but can be formed into an elliptical shape, a semicircular shape, a polygonal shape, or the like, if necessary, and the size can be arbitrarily selected. Further, the cutting line for incision can be selected from various modes such as the one shown in the broken line in addition to that in the above-mentioned embodiment, and the number, length, degree of bending, etc. can be freely selected and determined as necessary. You can

Although the material of each part was not particularly described in the description of both the examples, the backing support 1, the adhesive layer 2, and the peelable protective sheet 3 are conventionally used in the field of medical adhesive products. It can be composed of various materials.

For example, a suitable material for the backing support 10 has a thickness of 40 to 10
Examples include non-porous and perforated films made of 0 μm soft vinyl chloride, EVA resin, polyethylene, polyurethane, A / B / A type block copolymers and the like.

The adhesive may be medically non-toxic, non-irritating, and has sufficient adhesive strength. For example, natural or synthetic polyisoprene rubber alone or a mixed rubber thereof with SBR within 50% and a tackifier resin. (For example, polyterpene resin, ester gum, petroleum C _{4 to} C ₆ fraction polymer resin) and other rubber / resin-based, poly (meth) acrylic acid ester-based, polyvinyl ether-based, polyurethane-based adhesives It is suitable.

As the peelable protective sheet, paper alone, surface resin coated paper,
In addition to a laminated paper with a film or the like, a low-stretch or non-stretch plastic sheet in general (for example, PET) can be exemplified. The surface in contact with the adhesive surface is preliminarily subjected to a release treatment with a silicone release agent or the like.

(Effects of the Invention) According to the present invention, it is possible to provide an adhesive sheet for medical assistance having the following advantages.

Even if the fixed object is thick, it can be three-dimensionally dealt with by simply cutting a single sheet of adhesive sheet, and this can be done without any wrinkles or voids in the periphery or mischief. Can be stably fixed at a predetermined position.

Since it is attached to the skin so as to surround the periphery of the fixed object with an annular continuous adhesive surface portion, it does not require a large longitudinal skin surface for attachment as in the case of a conventional plaster, for example, but it does not have sufficient attachment force. A fixed force can be provided.

Compared to the case of using a long plaster as in the past, there is no feeling of tension when the skin is stretched, and since the tension does not work so much, it does not easily peel off and the reliable attachment state lasts for a long time. To be done.

The peripheral part of the fixed object itself is pressed almost entirely, but since it is fixed and pressed with a gap reaching the central part of the fixed object, it is stably and reliably fixed and at the same time the center of the fixed object is fixed. The thickness of the portion does not increase, it is light in use and appearance, and water easily diffuses from the skin.

The peelable protective sheet is also provided with a cut line at a position corresponding to the adhesive sheet main body, and since a cut line is provided to connect the hem portions of the cut line to each other, the peripheral portion of the adhesive surface is The work of peeling off the releasable protective sheet portion remaining after sticking to the skin around the fixed object is extremely easy and easy to use as a whole.
