[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patch for hemostasis.

[0002]

2. Description of the Related Art Conventionally, blood collection, infusion, blood transfusion,
Artificial dialysis and the like are widely performed, but are performed by puncturing a blood vessel from the skin surface with a needle, a catheter, a medical tube, etc., and after removing these needles, etc. Since the blood bleeds from the punctured part of the blood vessel, the patient is strongly pressed with a finger by applying absorbent cotton or gauze or pressed with an adhesive tape or an elastic band to stop the blood. However, in order to stop bleeding in this way, it is necessary to hold down firmly with a finger or a pressing tool for more than ten minutes, and if it is troublesome and you do not press chitin, subcutaneous bleeding or clothing It is not preferable because of contamination.

[0003]

SUMMARY OF THE INVENTION In view of the above, the applicant has provided a hemostatic patch to be used by sticking it to the puncture site immediately after pulling out a needle or the like, but has achieved great effects. This is further improved. When the injection needle or the like is thin, the hole of the puncture part for the blood vessel is small,
Hemostasis can be relatively easily performed on the venous duct.
However, in the case of a thick injection needle or the like, the hole becomes large and the amount of blood bleeding increases, so that it becomes difficult to stop the bleeding. In such a case, the bleeding can be easily and surely stopped.

[0004]

According to the present invention, a thick hard pad having an oval shape is fixed on a pressure-sensitive adhesive layer provided on one surface of a stretchable base material. The blood pad is strongly and intensively pressed by the pad to stop the bleeding, and at the same time, the bleeding from the puncture hole on the skin surface is absorbed by the pad so that the hemostasis is reliably performed.

[0005]

In the following, examples will be described. The substrate 1 is preferably made of a material having high elasticity, and has a high elongation and a high recovery rate. For example, a urethane nonwoven fabric can be suitably used. . An adhesive layer 2 is provided on one surface of the substrate, and the adhesive is preferably a rubber-based, acrylic-based, silicone-based, or vinyl-based adhesive that has a small stimulating effect on the skin.

A pad 3 is fixed on the pressure-sensitive adhesive layer. This pad has an oval shape with rounded corners having a long side of at least about 1 cm or more, and preferably has a long side of about 2 cm, and is thick and thin. It has a thickness of about 5 mm or more, preferably about 6-1
It is good to make it about 0 mm. If this thickness is thinner than 5mm,
The pressing action on the puncture portion described below becomes small, and it becomes difficult to perform reliable hemostasis. The one shown is about 2.7cm long,
The short side has an oval shape of about 1.5 cm, and its thickness is about 7 mm.

This pad has a surface layer 4 made of a material such as a non-woven fabric which absorbs blood quickly and a compression layer 5 made of a relatively hard material such as compressed cotton, which is laminated from the side in contact with the skin. It is formed in a state. And the above-mentioned compression layer 5
Occupies most of the whole thickness, and the surface layer 4 is formed thin. Further, a thin layer made of pulp or the like which is hardly adhered to the skin can be further provided on the surface of the surface layer 4 opposite to the compression layer 5.

The above pad is fixed on the pressure-sensitive adhesive layer of the substrate with spaces 8, 8 slightly smaller than the side edges 7, 7 of the substrate so that the long sides of the pad face the width direction of the substrate. In the illustrated example, the pad is fixed at a center of a tape-like base material having a length of about 8 cm and a width of about 3.3 cm with a space smaller than the pad thickness of about 3 mm from both side edges. ing.

The surface of the pressure-sensitive adhesive layer is covered with release paper and wrapped in a bag for sanitary and easy to use, and the one shown in FIG. The adhesive layer side is adhered, and the other adhesive layer side is covered with a release paper 12 having a folded piece 11 formed on the pad 3 side, and a wrapping paper 13 is placed thereon.
And the two wrapping papers 9 and 13 are peelably weakly bonded with a co-sealing agent or the like. Folded pieces 14 and 15 are provided at one end of the wrapping paper, respectively, as clues for peeling.

When this is used, the wrapping papers 9 and 13 are peeled off by holding the folded pieces 14 and 15, and when a finger is inserted under the release paper 12, the intrusion of the finger is prevented by the folded piece 11 and the pad is inserted. Therefore, if the release paper and the base material are sandwiched and peeled off from the release paper 10 on the wrapping paper 9 side, the product can be taken out from the wrapping paper.

[0011] This is placed on a 16-18 gauge (1.55-1.
Blood is collected and transfused using a thick needle such as 22 mm), and a pad is applied to the part from which the blood has been removed so that the long side is aligned with the direction in which the needle was inserted, and the base material is stretched while pressing. The exposed pressure-sensitive adhesive layer is attached to the skin while the folded piece 11 of the release paper 12 is picked up, the release paper is peeled off, and the base material is attached and fixed to the skin while being pulled.

In this case, the pad is located on the hole 16 of the subcutaneous blood vessel puncture portion and the puncture hole 1 on the skin surface.
7 will also be covered. Then, since the thickness of the pad and the stretched base material are strongly pressed downward by the action of contracting, the puncture hole 16 of the blood vessel is intensively pressed tightly and closed, and the blood stops reliably. be able to. In addition, the puncture hole 1 on the skin surface is generated by this pressing action.
Although blood comes out from tube 7 after extubation, it is immediately and easily absorbed by the surface layer of the pad, and when the amount is larger, it penetrates into the compression layer, is absorbed and held, and does not leak outside.

[0013] Further, since there is a small space 8, 8 between the both side edges of the base material and the pad, this portion bends obliquely downward on both sides of the pad when it is applied to the skin. Since the pressing action is applied downward on the oblique inner side, and the pressing action is also applied downwardly in the straight direction, the pressing action is concentrated on the pad without dispersing, and the thicker pad moves sideways. Since there is no such problem, the puncture hole of the blood vessel can be strongly and reliably pressed to stop the blood. Also, since the corners of the pad are rounded and oval, even if a strong compressing action is applied to the pad, the pad is soft and does not cause pain on the skin.

[0014] In this way, hemostasis is completed after a certain period of time with the product adhered, so that it can be removed from the skin surface, and the bleeding does not stain the clothes and the like.

In FIG. 6, release papers 18 and 19 covering the surface of the pressure-sensitive adhesive layer 2 are overlapped at a central pad portion, and are stored in a packaging bag 20.

[0016]

As described above, according to the present invention, even when a large puncture hole is formed in a blood vessel, it is possible to reliably stop the bleeding.
A gauge needle (diameter 0.76 to 0.57 mm) can be used effectively. Further, the operation at the time of use is easy, and the structure is simple and economical.
