Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In recent years, arterial puncture catheters, arteriography,
Treatments and tests involving arterial puncture such as intra-arterial injection are widely performed. Arterial puncture catheters are widely used, for example, to monitor arterial blood pressure during surgery and to collect arterial blood to know the condition of the lung from the blood condition. Has been done. In addition, arteriography is widely used not only for diagnosis but also for arterial embolization and percutaneous catheter angioplasty.

Conventionally, when such a treatment or examination involving arterial puncture is performed, an injection needle,
After removing the catheter, tube, etc., place the gauze and tie it with a large pillow-shaped pad.
After pressing and stopping the bleeding, this gauze is rolled and fixed with a bandage. After confirming that the bleeding has been stopped, the patient is returned to the ward or the like. In such so-called educational hospitals, doctors perform most of the hemostatic actions along with puncture, and in general hospitals, nurses often perform hemostasis, but post-operative nurses do much work. It remains, and the efficiency of such hemostatic work is desired.

Further, although various proposals have been made for a hemostatic material for a punctured portion in case of venipuncture, at present, there is no one that can easily and effectively perform arterial hemostasis. It's a reality.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, it is possible to easily and reliably prevent hemostasis after removing an injection needle or the like at an arterial puncture site after performing arterial puncture for treatment or inspection as described above. It enables you to do it.

[0006]

According to the present invention, an adhesive layer is provided on one side of a base material made of a stretchable material having a strong restoring action, and an arterial tube puncture hole and a skin surface are provided on the adhesive layer. An oval shape that allows both puncture holes to be pressed at the same time, and a thick pad with a slight elasticity and firmness is placed, and is attached to the puncture part, and the arterial puncture is performed using the pad. The purpose is to press the hole strongly to stop the bleeding, and also to allow the pad to absorb the bleeding from the skin surface puncture hole in order to surely stop the bleeding.

[0007]

EXAMPLES Examples will be described below. An adhesive layer 2 is formed on one surface of a substrate 1. The base material is preferably a stretchable material having a strong restoring action, and has a 100% elongation force (stress for 100% elongation) of about 450 to 600.
Those having a recovery rate of about 90% or more at 100% elongation in g / cm can be effectively used. As such a material, for example, there is a cloth-like material in which thin continuous filaments of polyurethane elastic fibers are randomly laminated and the intersections thereof are joined.

The pressure-sensitive adhesive of the above-mentioned pressure-sensitive adhesive layer is an acrylic type,
Appropriate materials such as natural rubber and silicone can be used, but acrylic is often preferable because it has less irritating effect on the skin. The pad 3 is placed on the pressure-sensitive adhesive layer, and the pad 3 has an appropriate compression hardness with a slight elasticity so as not to be easily deformed when compressed. This pad is formed in an oval shape so that both the arterial tube puncture hole 16 and the skin surface puncture hole 17 can be pressed when the injection needle or the like is pulled out, and its thickness is about 8 to 1 as well.
It is about 2 mm. In this case, when the thickness is further increased from about 12 mm, the pressing action becomes stronger, but the pad is rarely crouched or collapsed sideways, which is often not preferable. When the thickness is less than about 8 mm, it is often impossible to apply a sufficient pressing action to the puncture portion even if the above-mentioned base material has a strong restoring property.

In the structure shown in the figure, the pad is formed in a multi-layer structure, and a cushion layer 4, a lower layer 5, an upper layer 6 and a surface layer 7 are sequentially formed from the adhesive layer 2 side. The cushion layer 4 accounts for about 50 to 60% of the total thickness,
It is made of polyethylene or other plastic foam with a large content of closed cells, and has a slightly hard elasticity.
It has a sufficient restoring effect without the so-called settling phenomenon. The next lower layer 5 occupies about 20 to 30% of the thickness, has a compression action mainly on arteries, and can also absorb blood. Usually, compressed cotton is used, and for example, a cellulose nonwoven fabric is compressed. Cotton or the like is used.

The upper layer 6 occupies about 20% of the inside and outside of the thickness,
It is softer than the lower layer 5 and has a lower back to soften the contact with the puncture part. It can quickly absorb blood coming out of the puncture hole on the skin surface when the injection needle or the like is pulled out, and a non-woven fabric is usually used. It is preferable to use a rayon non-woven fabric as shown in the figure. The surface layer 7 is formed thinly to prevent fuzzing of the upper layer and to facilitate the exfoliation of coagulated blood, and it is preferable to use a perforated polyethylene film, a nylon net, a thin cellulosic nonwoven fabric or the like.
The lower layer 5 and the upper layer 6 may have a three-layer structure by using one having both properties and one layer.

Such a pad usually has a long side of about 20-.
If it is formed into an oval shape having a length of about 40 mm and a short side of about 10 to 20 mm, both the arterial duct puncture hole and the skin surface puncture hole can be pressed in most cases.

The pad 3 is usually placed in the central portion of the base material so that it can be attached to the puncture portion by the adhesive layer 2 provided on the base material 1. This substrate is a square,
It may be formed in a circular shape, an elliptical shape, or the like, but it is often preferable to form it in the shape of a long piece. When the pad is placed on such a strip-shaped base material, the pad may be placed so that the long side of the pad faces the short side side (width direction) of the base material. By pressing both the arterial canal of the puncture part and the puncture hole on the skin surface on the long side of this pad, pressure can be easily applied.After that, apply the adhesive layer of the base material to the skin surface. Then, reliable hemostasis can be easily performed. In the illustrated one, the long side of the oval pad is placed so as to form a right angle with respect to the longitudinal direction of the long piece-shaped base material, which is a preferable mode when pressing, but it should be oriented obliquely. It can also be placed stationary.

The pad is spaced from both side edges 8 and 8 of the substrate by a space 9 having a length shorter than the thickness of the pad, usually about 3 to 10 mm, preferably about 6 mm. If it is positioned in this way, when it is applied to the skin, this space 9 part bends to cover both sides of the pad and exerts a pressing action downward to the inside of the diagonal, so that the pressing action is dispersed. Without concentrating on the pad, it is possible to further prevent the thick pad from moving laterally or falling (FIG. 5). Further, since the space 9 is narrow as described above, the base material having the pressure-sensitive adhesive layer is not touched by the injection needle or the like when using it as described later even when the injection needle is pulled out while pressing it with the pad. It doesn't get in the way.

The surface of the pressure-sensitive adhesive layer of the above base material may be covered with a release paper, and if it is further packaged in a bag, it is hygienic and easy to use.
As shown in the drawing, the folded piece 11 is provided on the adhesive layer on both sides of the base material.
It is covered with a release paper 12 provided with, and is covered with a plastic cap 14 provided with a storage portion 13 in which the pad 3 is inserted, so that the pad is not deformed and is hygienically held. In addition, this is a co-worker with two more wrapping papers.
It may be enclosed in a packaging bag that is peelably adhered by a peeling agent or the like, or in some cases, the cap may be omitted and the packaging bag may be enclosed (not shown).

In the case of using this, taking the one shown in the drawings as an example, the cap 14 is removed, and a base material is held so that a finger can be inserted between the folded pieces 11 of the release paper 12 (FIG. 4). For example, as shown in FIG. 5, blood is collected from the radial artery of the wrist using a needle at about 22 to 23 gauge positions,
After using the catheter at about 20 gauge, before pulling out the needle, adjust its long side to the direction of the puncture needle, that is, the running direction of the arterial tube 15. Then, press the needle to remove the needle, press the pad, and then remove the release paper on one side, while pulling the base material, move the adhesive layer in the direction crossing the running direction of the blood vessel. Face to the skin, then the other piece of the release paper is picked up to peel off the release paper, and the base material is also attached to the skin while being pulled and fixed.

In this way, the pad is positioned above the subcutaneous arterial puncture hole 16 and covers the skin surface puncture hole 17 as well. Then, due to the action of the stretched base material to contract, the pad is pressed downward, but the pad is pressed down strongly due to the multilayer structure including the cushion layer, although it is soft against the skin. , Puncture hole 16 in arterial tube 15
The part of is closed intensively with strong pressure, and it is possible to surely stop the bleeding. Also, due to this pressing action, blood comes out from the skin surface puncture hole 17 after the needle is removed, but it is immediately and easily absorbed by the surface layer 7 of the pad, and when the amount is larger, it penetrates into the upper layer 6 and is absorbed and retained. Therefore, blood does not leak outside.

In this way, the hemostasis is completed after a certain period of time with the product attached, so that it can be removed from the skin surface, and clothes and the like will not be contaminated by bleeding. In addition, when attaching the base material to such a wrist, it is useful to prevent the base material from wrapping around the entire circumference of the wrist so that hemostasis of the necessary part can be accurately performed without blocking other blood circulation. There are many.

In FIG. 6, the shape of the pad 3 is a frustum shape in which the area of the side of the base material located above the pressure-sensitive adhesive layer is increased, and in such a case, it is attached to the puncture portion. In case, it can be pressed onto the pad in a stable state,
The pad may be collapsed further and may be effectively used. 7 has a shape in which the corners on the surface layer side of the pad are chamfered, and the contact with the skin becomes softer. In the structure shown in FIG. 8, the surface layer 7 and the upper layer 6 that contact the skin are formed to be slightly smaller, and the stability when the pad is fixed is further increased, and the compression action can be concentrated. Any of the materials shown in FIGS. 6 to 8 can be attached and used in the same manner according to the above.

[0021]

[Measurement of compressive force] As shown in FIG. 9, the pressure-sensitive adhesive layer of the above prototype was attached to a measuring base 21 made of Bakelite, and the pad was used with a rheometer using a probe 22 of 20 mmφ. The surface of the probe was pressed so as to match the surface of the measurement stand, and the pressing force after 1 minute was measured. The measurement was performed on ten prototype examples.

[Result] Pressure force 360 ± 12g / cm ²

[Discussion] When the gauze that was conventionally used is rolled and fixed with a plaster to stop bleeding, a compression force of approximately 250 g / cm ² is considered to be applied, so sufficient compression force is used in the prototype. Is obtained, which shows that it is useful as an arterial hemostatic material.

[0022]
