Abstract

PURPOSE: To make it surely and easily possible to compress the blood vessel of the part where the venous cancer is generated by providing the subject patch material with such a pad capable of covering the skin surface where the venous cancer injected with an oxidizing agent exists and fixing this pad on a tacky adhesive layer. CONSTITUTION: This patch material for compression is formed by placing the pad 1 for compressing the venous cancer on the tacky adhesive layer 3 formed on one surface of a base material 2. The pad 1 is formed into a multilayered structure consisting of, preferably, a lower layer 11, a middle layer 12 and a surface layer 13, so as to have slight elasticity and adequate compression hardness to the extent that the pad is slightly deformed without easy deformation when the pad is pressed. This lower layer 11 occupies about the half part of the thickness over the entire part and compressed cotton, etc., having some hardness, stiffness and elasticity are used for this layer. The middle layer 12 occupies about 40% of the thickness over the entire part and, for example, laminated rayon wadding, laminated cellulose wadding, etc., which are slightly softer than the lower layer and are slightly less stiff are used for the middle layer 12. A non-woven fabric, woven fabric, knitted fabric, etc., which do not impart excess stimuli to the skin are used for the surface layer 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patch for use in sclerotherapy for varicose veins by pressing a vein portion in which a varicose vein is to be cured and occluding and hardening the vein portion.

[0002]

2. Description of the Related Art Varicose veins are those in which the venous canal becomes stagnant and forms a bulging aneurysm due to a failure of the venous regurgitation valve, and it appears especially in the superficial venous canal of the lower limbs of elderly women who continue to work. There are many patients, and there are many patients, and symptoms such as fatigue in the lower limbs, feeling of weight in the lower limbs, pain during standing for a long time, and spasms of the legs at bedtime may appear. Since it is present, it is not good for beauty.

Heretofore, as a method for treating such varicose veins,
A stripping method was used to remove a part of the varicose vein by surgery, but recently, sclerotherapy for varicose vein has come to be performed because it does not require hospitalization and can be treated as an outpatient visit. . In this sclerotherapy, a sclerosing agent is injected into the varicose vein to harden and retract the varicose vein.After injecting the sclerosing agent, the blood vessel at the varicose vein is compressed and crushed. While curing. This compression operation is performed by applying a cotton ball or a folded gauze on the varicose vein and wrapping an elastic bandage on it, but since it can not be wrapped too tightly, the compression force may be insufficient. However, the elastic bandage often slides down quickly and the compression action is often unstable, which is not satisfactory.

[0004]

Therefore, it is an object of the present invention to obtain a varicose vein-generating blood vessel that can be reliably and easily pressed after the hardening agent is injected.

[0005]

The present invention provides a pad capable of covering a skin surface where a varicose vein in which a hardening agent is injected is present, and an adhesive layer formed on one surface of a base material of the pad. Placed on top, the base material should be flexible enough to restore the pressure so that the varicose vein can be pressed by sticking it to the skin surface with its adhesive layer. Be sure to keep the pressure until it hardens.

[0006]

EXAMPLES The details of the present invention, together with the examples thereof, are as follows.
The pad 1 for pressing the varicose vein is placed on the adhesive layer 3 formed on one surface of the base material 2. The pad 1 has a small amount of elasticity and an appropriate compression hardness such that it is not easily deformed when pressed, and has a size capable of covering the varicose vein to be cured. have. The thickness of the pad is about 5 to 20 mm, preferably 6 to
It is good to set it to around 15 mm.

As shown in the figure, this pad is formed in a multi-layered structure, and the lower layer 11 and the middle layer 1 are formed from the adhesive layer 3 side of the substrate 2.
2, the surface layer 13 is provided. The lower layer 11 occupies about half of the total thickness, and is a compressed cotton having a firm and elastic elasticity, such as a cellulose nonwoven compressed cotton, a polyester nonwoven compressed cotton, polyethylene having a large content of closed cells and the like. It is preferable to use a plastic foam or the like. The next middle layer 12 occupies about 40% of the total thickness, and is slightly softer and slightly weaker than the lower layer. For example, laminated rayon cotton or laminated cellulose cotton is used. Surface 1
No. 3 is a non-woven fabric, a woven fabric, a knitted fabric or the like, which is soft to the skin surface, does not slip on the skin surface, and does not give excessive irritation to the skin. , Cellulose nonwoven fabric, etc. can be used. Such a pad may be formed by omitting the surface layer 13 to have a two-layer structure of a lower layer and a middle layer, a single layer structure of one of the lower layer and the middle layer, or a further increased number of layers. .

The base material 2 is formed of a material having both elasticity and strong resilience in which the stretched material tries to shrink to its original state. As such, for example,
There are elastic non-woven fabrics, especially elastic urethane non-woven fabrics, and the 50% elongation force (stress when extended by 50%) is about 200 to 600 gf / cm, preferably 200 to 30.
About 0 gf / cm, recovery force at 50% elongation is about 90%
The above is preferable.

As the pressure-sensitive adhesive of the pressure-sensitive adhesive layer 3 formed on one surface of the base material 2, a rubber-based, acrylic-based, silicon-based, vinyl-based or other pressure-sensitive adhesive can be used, but the sticking time becomes long. Since it is often the case, it is often preferable to use an acrylic resin that causes less chemical irritation to the skin. The pad 1 is placed on the pressure-sensitive adhesive layer 3 and is usually fixed in place by the pressure-sensitive adhesive, but it may be fixed by using another adhesive or pressure-sensitive adhesive.

As shown in the figure, a strip-shaped pad 1 is provided in the central portion of a rectangular base material 2 of about 11 × 15 cm so as to extend in the direction of its narrow width. And a meeting was held on the pad 1 at the center 2
The release paper 4 is covered.

The size and shape of the base material and the pad can be appropriately selected according to the length, width, spread, size and other conditions of the varicose vein to be applied. The shape may be a shape, an ellipse, a circle, a polygon, or any combination of these. The pad shown in FIG. 5 is a square pad, and can be effectively used, for example, when small varicose veins are more concentrated.

[0012] When this is used, the blood in the relevant vein such as the lower limb 6 is usually removed by air, and the blood remaining in the aneurysm is suctioned and removed by a syringe or the like. Then, an injection needle such as a winged needle is pierced into the varicose vein to inject a curing agent into the varicose vein. After the injection, the adhesive sheet 5 while peeling off the release paper
The pad is pressed against the varicose vein and pressed from above, and the base materials on both sides are slightly stretched, and the adhesive layer is applied to and fixed on the skin surface.

In this way, the blood vessel in the varicose vein is covered with the pad, and the slightly stretched base material presses the pad against the blood vessel in the varicose vein by the restoring action of shrinking to the original state. The condition can be maintained and effective compression can be applied to this varicose vein. Typically, this should provide a compressive effect of about 20-40 mmHg. Since the pad has appropriate softness in its compression hardness, it does not hit the skin lightly and does not move and does not give extra irritation.

The varicose vein-generating blood vessel is kept flat and crushed by the pressure of the pad, and the hardener hardens the portion. It takes a considerable amount of time for this curing to finish, but it is recommended to increase the amount of extension of the base material to increase the amount of expansion for a little about 3 to 4 days after the curing treatment. During this period, it is advisable to gradually weaken the compression effect. A varicose vein hardens and disappears under the pressure of such a pad, and a new vein is born.
The above-mentioned patch may be left in a state where it is continuously stuck, but it may be replaced at an appropriate interval such as every day. Further, the adhesive patch may be used after the curing treatment, and thereafter, the elastic stockings may be used to use both of them together.

[0015]

Industrial Applicability As described above, the present invention is applied by simply applying a pad on the vein-occurring site blood vessel in which a hardening agent has been injected, and then applying it to the surface of the skin with the adhesive layer of the base material. The varicose vein can be surely kept pressed until it hardens in a crushed state while softly contacting the skin without slipping.
