DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a disposable hemostatic bandage having a hemostatic member.

[0002]

2. Description of the Related Art In general, dialysis needles and blood transfusion needles used for artificial dialysis and blood transfusion are thicker than injection needles used for blood collection during mass screening, so that a large amount of bleeding is caused, and gauze is applied to a portion from which the needle is removed. It is necessary to stop and stop bleeding strongly. Conventionally, for example, in the case of using a surgical tape, since it is not easy to hold down, it has to be wrapped around the affected part such as an arm multiple times and widely, not only is the work complicated, but also the bleeding material of the adhesive is This is a cause of rough skin, and has become a serious problem particularly for people with sensitive skin such as dialysis patients.

[0003] When a bandage having Magic Tape (registered trademark) at both ends is used, the magic tape is not coated with an adhesive, so that there is no problem such as the above-mentioned surgical tape. It is difficult to stop the bleeding by properly holding the blood, and it tends to be recycled because it is expensive, but there are cases where it is used by others with blood attached. There was a problem. In particular, for example, when blood from a patient with fulminant hepatitis B or hepatitis C to which blood is adhered is used again, an alarming situation may be caused.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the conventional bandage used for hemostasis, and provides a bandage for hemostasis that is easy to use and has excellent safety. The purpose is to do.

[0005]

In order to achieve the above object, the present invention has a hemostatic member and a skin adhesive portion provided with an adhesive layer at one edge in the longitudinal direction. ,
An elastic bandage having a fixing portion provided with an adhesive layer on the other end edge portion, wherein a hemostatic member is provided at an end portion adjacent to the skin adhesive portion to provide a disposable hemostatic bandage. .

According to a second aspect of the present invention, there is provided the disposable hemostatic bandage according to the first aspect, wherein the hemostatic member is a polyolefin foam and the elastic bandage is a polyurethane nonwoven fabric. In addition, the present invention according to claim 3 provides the disposable hemostatic bandage according to claim 1 or 2, wherein a release material layer is laminated on the adhesive layer. Hereinafter, the present invention will be described in more detail.

The elastic bandage used in the present invention comprises:
Air permeable, 10% modulus 0.5-3N / 19
mm flexibility, 30 to 30 mm in the length and width directions
Preferably, it has a stretch of 600%. When these characteristics are satisfied, the bandage is easily stretched since it has moderate waist and stretch. In addition, the weight is 3
It is preferably about 0 to 120 g / m ^{2 in} that it is light and can exhibit the above characteristics more. The width varies depending on the affected area, but is usually 10 to 50 mm, preferably 25 to 40 mm.
Degree. The base material of the elastic bandage is not particularly limited, but can have the above characteristics, and is inexpensive.
Polyurethane nonwovens are particularly preferred.

[0008] The material of the hemostatic member used in the present invention is not particularly limited as long as it has at least a little blood absorbability and retention after adhesion. Foams, polystyrene foams, polyurethane foams, vinyl chloride foams, etc., include foam processability, moderate hardness for contacting and adhering to skin, blood absorbency, and cost. From the overall viewpoint such as the above, a polyolefin foam, particularly a polyethylene foam is preferably used.

When the height of the hemostatic member is too low, pressure is not easily applied to the affected part, so that the hemostatic effect is poor.
m is preferable, and 10 to 15 mm is more preferable.
In addition, it is preferable that the corners of the portion that comes into contact with the skin and the portion around which the bandage is wound have appropriate roundness (see FIG. 1). The width is usually 5 to 20 mm, and 8 to 15 m
In the case of m, fixation is stable and particularly preferable. If the hemostatic member is too soft, the hemostatic effect is poor, and if it is too hard, the skin feels painful. Therefore, in the case of polyethylene foam, the expansion ratio is usually 3 to 10 times, preferably 5 to 10 times.

For example, the expansion ratio is 3 to 10 times, preferably 5 to 10 times, and the height is 3 to 15 mm, preferably 10 to 10 times.
A polyethylene foam of 15 mm and a width of 5-15 mm (the dimensions of the other pieces are the same as the width of the elastic bandage), preferably 5-10 mm, is preferably used as the hemostatic member.

In the present invention, a pressure-sensitive adhesive layer is provided on the skin bonding portion and the fixing portion, but this pressure-sensitive adhesive layer is not necessarily a layer uniformly formed on the outer surface of the base material of the elastic bandage. For example, if it is possible to adhere to the skin by pressing or fix the elastic bandage, the base material of the elastic bandage may be partially impregnated in the base material. Such a pressure-sensitive adhesive is not particularly limited, and a conventionally known pressure-sensitive adhesive of a natural rubber type, a synthetic rubber type or an acrylic resin type can be used, and one having an adhesive force of 1.5 to 6 N / 19 mm is preferably used. Is done.

When the coating amount of the pressure-sensitive adhesive layer having the above-mentioned pressure-sensitive adhesive strength is set to 20 to 50 μm, the pressure-sensitive adhesive strength to the skin becomes the most appropriate, and the adhesiveness on the back surface of the fixing portion is improved. In particular, when 0.5 to 3 parts by weight of an isocyanate compound is blended as a crosslinking agent with respect to 100 parts by weight of an acrylic pressure-sensitive adhesive, a pressure-sensitive adhesive layer excellent in durability and penetrability into a substrate is formed. You.

A stretchable bandage 2 made of a urethane non-woven fabric base material, a pressure-sensitive adhesive layer 23 is provided on one edge 21 of the elastic bandage 2 to form a skin adhesive portion 25, Further, an adhesive layer 24 is provided on the other end edge portion 22 of the elastic bandage 2 to form a fixing portion 26.

The hemostatic member 1 is attached to an adhesive layer 23 ′ extending from the adhesive layer 23, and is provided at an end portion 28 at a position adjacent to the right of the skin adhesive portion 25. Hemostatic member 1
It is convenient to use a pressure-sensitive adhesive as shown in FIG. 1 as described later to provide the end portion 28 with the end portion 28. However, it is not always necessary to use this method. Is also possible.

The width W of the elastic bandage 2 is 25 to 40 mm, and the width a of the skin-adhered portion which contacts and adheres to the skin is 30.
血 60 mm is desirable, and the hemostatic member 1 having a width of 5-20 mm is disposed beside it. In particular, it is desirable that the width a of the skin adhesive portion that comes into contact with the skin is as narrow as possible due to problems such as rash.

When the width b of the pressure-sensitive adhesive layer 24 is too narrow, the fixed portion cannot be fixed sufficiently. On the contrary, when the width b of the pressure-sensitive adhesive layer 24 is too narrow, it is difficult to peel. The width b of the pressure-sensitive adhesive layer 24 is preferably 15 to 35 mm. For convenience of use, release papers 31 and 32 constituting a release material layer are provided on the skin adhesive portion 25 and the fixing portion 26, respectively.
Are preferably laminated.

In order to use the disposable hemostatic bandage of the present invention, for example, the hemostatic member 1 is bleeding in a state where the release paper 31 of the skin adhesive portion 25 is peeled off and the adhesive layer 23 is exposed (see FIG. 1). (Bleeding) Adhesive layer 2 while applying to affected area
After the elastic bandage 2 is wound an appropriate number of times, the release paper 32 of the fixing portion 26 is peeled off, and the adhesive layer 24 is pressed against the back of the elastic bandage 2. It is good to apply and adhere. Alternatively, the hemostatic member 1 may be applied to the affected part while the adhesive layer 23 is attached to the skin.

The release paper 31 of the skin adhesive portion 25 is not only laminated on the pressure-sensitive adhesive layer 23 as shown in FIG. 1, but may be extended to the hemostatic member 1 so as to be easily peeled off.

In order to manufacture the disposable hemostatic bandage of the present invention, for example, release paper (weighing 100 to 150 g / m ² ) obtained by laminating a polyethylene film on the surface of high-quality paper and subjecting it to silicone processing. 3, after applying and drying an acrylic pressure-sensitive adhesive to a thickness of 20 to 50 μm as shown in FIG. 2, laminating a urethane non-woven fabric base material and winding to a length of 500 to 1000 m. Produce an adhesive substrate.

The pressure-sensitive adhesive layers 23, 24 formed at this time
Is located slightly inside the edge of the base material web width as shown in FIG. 2 and has an ear portion (the pressure-sensitive adhesive layer 23 ′ shown in FIG. Omitted).
Thereafter, the ears on both sides of the adhesive sheet are cut off, and the release paper is further cut with a slitter (a cut may be made in the release papers 31 and 34), and the end of the elastic bandage 2 in FIG. The release paper is removed from the portion corresponding to the inside of the other end edge portion 26 from the inside of 28, and winding is performed while maintaining the state of FIG.

Next, the width of the elastic bandage 2 is 10 to 50 m.
m, the release paper 34 located on the end 28 is completely peeled off and the hemostatic member 1 is fixed on the exposed adhesive layer 23 ′, and the disposable hemostatic bandage shown in FIG. 1 is obtained. Is obtained. In this case, the release paper 34 is

Alternatively, the adhesive layer 23' may be peeled off so as not to cover the surface, but kept in a continuous state without being separated from the release paper 31. (That is, in the latter case, it is not necessary to make cuts in the release paper corresponding to 31 and 34 in the previous process).

Example 1 A disposable hemostatic bandage similar to the disposable hemostatic bandage shown in FIG. 1 was used except that the release paper 34 was integrally connected to the release paper 31. That is, a hemostatic member made of a polyethylene foam is attached to a stretchable bandage made of a polyurethane nonwoven base material having air permeability, and the foam has a foaming magnification of 5 times and a height of 12 m.
m and a width D of 14 mm, and a fixed part and a skin-bonded part were formed using an acrylic resin-based adhesive having an adhesive strength of 4 N / 19 mm. 1 is 40 mm and b is about 30 in FIG.
mm.

Immediately after the dialysis needle or blood transfusion needle was removed from the subject's arm, gauze was applied.
In a state where the adhesive layer 23 is exposed by peeling off the adhesive layer 23, the adhesive layer 23 is attached to the affected part adjacent to the hemostatic member 1 while applying the hemostatic member 1 to the skin so as to come to the affected part from which the needle has been removed. After the elastic bandage 2 is wound a few times while being slightly stretched, the release paper 32 of the fixing portion 26 is peeled off, and the adhesive layer 2 is removed.
4 was pressed against the back of the elastic bandage 2 and adhered and fixed.

The fixing portion 26 was not peeled off from the elastic bandage 2 or the position of the hemostatic member 1 was not shifted, and the hemostatic property was extremely good. In addition, there was no occurrence of skin rash or rough skin.

Example 2 A disposable hemostatic bandage similar to the disposable hemostatic bandage shown in FIG. 1 was used. That is, to a stretchable bandage made of a polyurethane nonwoven base material having air permeability, a hemostatic member made of a polyethylene foam is attached,
The expansion ratio of the foam is 8 times, the height is 12 mm, and the width D is 14
mm and an adhesive strength of 3 N / 19 mm to form a fixed part and a skin-bonded part. The dimension a in FIG. 1 was 40 mm, and the dimension b was about 30 mm.

Gauze was applied immediately after the dialysis needle or blood transfusion needle was removed from the subject's arm.
In a state where the adhesive layer 23 is exposed by peeling off the adhesive layer 23, the adhesive layer 23 is attached to the affected part adjacent to the hemostatic member 1 while applying the hemostatic member 1 to the skin so as to come to the affected part from which the needle has been removed. After the elastic bandage 2 is wound a few times while being slightly stretched, the release paper 32 of the fixing portion 26 is peeled off to remove the adhesive layer 2.
4 was pressed against the back of the elastic bandage 2 and adhered and fixed.

The fixing portion 26 was not peeled off from the elastic bandage 2 or the position of the hemostatic member 1 was not shifted, and the hemostatic property was extremely good. In addition, there was no occurrence of skin rash or rough skin.

(Comparative Example) When a surgical tape is used, it is difficult to press on the arm, so it must be wrapped around the affected part of the arm or the like multiple times and widely. (Comparative Example 1). In addition, when a bandage provided with a magic tape at both ends was used, it was difficult to accurately hold the portion from which the needle was removed (Comparative Example 2). Table 1 summarizes the hemostatic properties, skin roughness, skin swelling and rash, and the presence or absence of peeling at the end of the bandage in Examples 1 and 2 and Comparative Examples 1 and 2.

[0029]

[Table 1]

[0030]

The disposable hemostatic bandage of the present invention is constructed as described above and is disposable. Therefore, the bandage is much safer than a bandage provided with magic tape at both ends, which is often reused. It is high, and the skin adhesive portion is provided at a position adjacent to the hemostatic member, so that the hemostatic member is hardly displaced from the affected part, and it is not necessary to wrap the bandage over and over as in the case of using a surgical tape. It is good and practically has a great effect without causing rough skin or rash. Further, when the hemostatic member is a polyolefin-based foam and the elastic bandage is a polyurethane-based nonwoven fabric, the above-described effects can be more reliably achieved, and the bandage for disposable hemostatic can be provided at low cost. Further, when a release layer is laminated on the pressure-sensitive adhesive layer, it becomes more convenient to use.
