Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hemostatic device.

[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.

When performing a treatment or an examination involving this arterial puncture, there are many cases in which an injection needle, a catheter, a medical tube or the like is left indwelling for a long time, and conventionally, in most cases, the treatment or the like. After that, the injection needle, catheter, medical tube and the like are removed from the arterial tube, and alcohol cotton is pressed against the removed portion (puncture portion) with a hand for about 10 minutes or longer. After that, a gauze is placed on the puncture part, and a large pillow is put on the puncture part to tie it up, and the arterial tube is pressed to stop the bleeding. Although doctors or nurses perform hemostasis after treatment with such arterial puncture, much work remains for doctors and nurses after treatment, and it is hoped that such hemostatic work will be efficient. It is rare.

[0004]

DISCLOSURE OF THE INVENTION The present invention can easily and surely stop bleeding after removing an injection needle or the like at a blood vessel puncture portion after performing a treatment or an examination by puncturing an artery as described above. To do so. Further, the present invention intends to replace the pad positioned at the puncture portion so that hemostasis can be economically achieved.

[0005]

According to the present invention, a pad is placed so as to cover a puncture portion for a blood vessel, the pad is fixed to a diseased portion with a binding band, and the puncture portion of the blood vessel is pressed by the pad to ensure the reliability. He is trying to stop hemostasis. Further, the pad is detachably temporarily fixed to the binding band so that the pad can be replaced. Further, a strong pressing portion is located on the side opposite to the side where the pad faces the puncturing portion, so that the pressing action is more reliable.

To describe the details of the present invention with reference to the drawings, a pad 1 to be placed on the skin surface is prepared. This pad has a size such that it can be pressed by covering it from above the blood vessel puncturing portion when the injection needle or the like is pierced from the skin surface toward the blood vessel, and its shape is rectangular, square, rectangular, It can be formed in any suitable shape such as a circle, an ellipse, an oval, a polygon, or the like. For example,
3 has an oval shape, and FIGS. 7 and 8 have a circular shape.

In this case, the pad 1 can press the blood vessel puncture hole 3 when the injection needle or the like is pierced from the skin surface toward the (arterial) blood vessel 2 as shown in FIG. It is particularly preferable that the puncture hole 4 be covered and pressed at the same time. The distance between the puncture holes 3 and 4 varies depending on the body part to be punctured, the age of the infant or adult, and the sex, but the pad size is usually about 1 to 4 cm in the long side. In many cases, it is enough. In the case of an ellipse, an oval, a rectangle, etc., it is generally preferable that the ratio of the short side to the long side is up to about 1: 4, and that of a square or a circle has a ratio of 1: 1. Therefore, the range is often about 1: 1 to 1: 4, but is not limited to these.

In the case of rectangles, squares, polygons and other shapes with corners, chamfering the corners in an arc shape is more preferable because it causes less irritation to the skin surface when pressed. Also, this pad is shown in FIGS.
As shown in Fig. 7, it is usually convenient to press both the blood vessel puncture hole and the skin surface puncture hole by forming an oval shape with the long side of about 15 to 40 mm and the short side of about 8 to 25 mm. When both holes are close to each other, a small circle, a square or the like may be used. It is preferable that this pad has an appropriate hardness so that the puncture portion can be surely pressed, for example,
A pad having a slight elasticity and a suitable compression hardness so as not to be easily deformed when compressed can be preferably used.

The pad has an appropriate thickness so that the puncture hole can be pressed when it is applied to the puncture part. Although it depends on the application site, it has a thickness of about 2 mm or more, and it is usually good to set it to about 3 to 20 mm. In this case, if it is too thin, effective compression may not be possible depending on the application site. In general, a pad with a relatively small thickness may be used for hemostasis of the radial artery, the dorsalis pedis artery, etc., and a pad with a relatively large thickness may be used for the femoral artery or the like. Further, as the thickness of the pad increases, the pressing action becomes stronger, but in the case of a small area, the pad rarely laterally crouches or falls down, and this point needs to be taken into consideration. In many cases, a thickness of about 3 to 16 mm is often preferable.

This pad may be formed in a single layer structure (FIGS. 7-10, etc.) or in a multi-layer structure (FIGS. 1-3, FIG. 1).
3rd grade). In the case of a single layer, it can be made using closed-cell or high-closed-cell plastic foam, compressed cotton, non-woven fabric, rubber or other materials. Further, in the case of the multi-layer structure, it is preferable to combine those having various properties to enable effective compression and the like.
In the case shown in (1), the surface layer 5, the upper layer 6, and the cushion layer 7 are sequentially formed from the side in contact with the skin surface. The surface layer 5 is formed to be thin, prevents fuzzing of the upper layer, and improves separation from coagulated blood. Next upper layer 6
Has a compressive effect and can quickly absorb blood. The cushion layer 7 has a slightly hard elasticity in order to obtain a compression effect, and has a sufficient restoring action without causing a so-called fatigue phenomenon.

The surface layer 5 may be made of perforated polyethylene film, nylon net, rayon net, thin cellulose nonwoven fabric, or the like. The upper layer 6 uses a non-woven fabric such as a rayon non-woven fabric. The cushion layer 7 is made of polyethylene, polystyrene, synthetic rubber or other plastics foamed material having closed cells or a large content of closed cells,
It is made of compressed cotton, such as polyester nonwoven compressed cotton.
The cushion layer 7 is made of closed-cell polyethylene foam so as to occupy about 2/3 of the total thickness, and the upper layer 6 is made of rayon non-woven fabric so as to occupy about 1/3 of the thickness. The use of a thin cellulosic nonwoven fabric for the surface layer 5 is an example effective for hemostasis of arteries (FIG. 3).

Further, the upper layer 6 is divided into two layers, and the cushion layer 7 side is made a layer which has a compressing action and can also absorb blood. For example, a compression cotton such as a cellulose nonwoven compression cotton or a laminated layer. It is also possible to use a non-woven fabric such as rayon non-woven fabric as a layer that uses cotton cotton or the like, softens the contact with the puncture portion on the surface layer 5 side, and can quickly absorb blood. Further, the upper layer 5 and the surface layer 6 may be a single layer, for example, to have a two-layer structure as a whole.

The pad is pressed by the binding band 8 toward the puncture hole 3 to stop the bleeding. This tie band is wrapped around the affected area where hemostasis is to be performed so that the pad can be pressed into the puncture hole, and cloth, rubber cloth, plastic, rubber, non-woven fabric and other band-shaped materials can be used. As the material, a material having elasticity, a material having no elasticity, a combination of materials having elasticity and materials having no elasticity, and the like can be appropriately used. In order to hold the binding band wound around the affected area, a hook-and-loop fastener, an adhesive, a locking metal fitting or other locking means may be used, and if the hook-and-loop fastener 39 is used, the locking position can be easily changed. It is often convenient because the pressing action of the pad can be finely adjusted.

Although the pad 1 can be directly pressed by the binding band 8, it can be pressed by positioning a strong pressing portion on the pad. This pressing portion 9 is a plastic plate (for example, an acrylic plate, a polypropylene plate, a nylon plate, a polycarbonate plate, a polyethylene plate, etc.), which is a separate body from the binding band 8, a metal plate, a plywood plate, a ceramic plate, and the like. It can be formed of an appropriate plate-shaped body. The plate-shaped body 10 is generally thin, but a thick one or a thin one bent to be thicker may be used. The plate-shaped body serving as the pressing portion is usually formed to be larger than the pad, but it may have the same size, one side may be smaller, or the whole may be smaller.

The pad can be fixed to the plate-like body 10 by an adhesive or the like so as to be integrated, and the both can be temporarily fixed removably by adhesion, fitting, engagement or other means. You may Such a plate-like body can be attached to the above-mentioned binding band by a hook-and-loop fastener, an adhesive, a band-sealing body or the like, and its mounting position can be changed or can be temporarily fixed detachably. It can also be attached. In the above, the plate-shaped body of the pressing portion is formed separately from the binding band, but as will be described later, it is also possible to form the pressing portion that also has the function of the plate-shaped body on the binding band itself. it can.

In the structure shown in FIGS. 1 to 3, the pad 1 is formed into an oval shape, and the cushion layer 7 thereof has a thickness of about 2 / about the total thickness.
3 is a closed-cell polyethylene foam, the upper layer 6 is made of rayon nonwoven so as to occupy about 1/3 of the thickness, and the surface layer 5 is made of thin cellulose.
Uses non-woven fabric. In addition, the binding band 8 is formed by a band-shaped cloth having elasticity and containing rubber having a fine loop-shaped surface 11, and a ring 12 is provided at one end thereof.
And a hook-shaped surface fastener 39 is attached to the other end.

The pressing portion 9 is formed on a plate-shaped body 10 which is separate from the binding band 8. The plate-shaped body is formed in a rectangular shape having a width slightly shorter than the width of the binding band and a thin thickness. The plate-shaped body 10 placed on the band is provided with a recess 13 as a knob at the center of the side edge along the longitudinal direction, and each corner is formed in an arc shape. An oval recess 1 is formed on one surface of the plate body 10.
4 is formed so that the cushion layer 7 side of the above-mentioned oval-shaped pad fits into the recessed portion 14 and can be detachably locked by the elasticity of the cushion layer 7.

A hook-shaped surface fastener 15 is attached to the other surface of the plate member. By pressing the surface fastener of the pressing plate against the binding band, it can be temporarily attached at a desired position. At this time, the long side of the pad is oriented in a direction at a right angle to the longitudinal direction of the binding band, which is a preferable mode when pressing, but the pad is slanted at an appropriate angle other than a right angle. You can also turn it over. Further, the pad can be positioned so as to be displaced to one side of the pressing portion.

When this hemostatic device 16 is used, the pad 1 is attached to the plate-shaped body 10 temporarily attached to the binding band 8, and the plate-shaped body 10 is picked from both sides from the binding band side, for example, as shown in FIG. About 20-24 gall in radial artery of wrist 37
After blood is collected using the needle in the di position, a pad is put on the arterial tube 2 on which the needle was stuck and pressed. Further, the pad is continuously pressed, the binding band is wrapped around the wrist, and the other end of the surface fastener 39 is pressed against the surface of the binding band 8 while being pulled while passing through the ring 12.

In this case, the pad is located above the subcutaneous arterial puncture hole 3, and the pressing action of the binding band 8 which is about to contract is concentrated on the pad, and the pad is strongly pressed downward. Thereby, the puncture hole 3 of the arterial tube 2
The part of is closed intensively with strong pressure, and it is possible to surely stop the bleeding. When wrapping the above, the pressing action of the pad can be adjusted by the extent to which the binding band is extended, and if an appropriate scale is displayed on this binding band, it will be a guide when locking the other end of the band. And become easier to use.

In this way, hemostasis is completed when a certain period of time has passed. Usually, after about 5 to 30 minutes, usually about 10 to 20 minutes after pasting, the binding band is loosened and removed from the wrist, and the pad 1 is pulled out from the recessed portion 14 of the plate-shaped body 10 and discarded. Good. When it is used again, if the pad 1 is fitted into the recessed portion 14 of the plate-shaped body 10,
It can be used in the same manner as described above.

In the structure shown in FIG. 5, a part 17 of the plate-shaped body 10 on the pad 1 side is formed to be somewhat smaller, and a recess 14 is formed.
Is provided. Further, in the one shown in FIG. 6, the pad 1 is fixed to a small plate body 18, and the portion of the plate body 18 is inserted into the groove portion 19 provided in the plate body 10 from the lateral side thereof.
It can be temporarily fixed. When the hemostasis is completed, the plate 18 with the pad 1 can be removed and removed, and a new plate 18 with the pad 1 can be inserted and attached to be used again.

In FIGS. 7 to 8, a strip 2 made of elastic rubber cloth is provided on both sides of a slightly thick plastic plate 20.
1 is attached to form a binding band 8. The plate 20 serves as a pressing portion 9, and this pressing portion is integrated with the binding band. The pad 1 has a round shape, and an adhesive layer 22 is formed on one surface thereof. The pressure-sensitive adhesive layer 22 is attached to the plate 20 of the pressing portion 9 and temporarily fixed,
If a binding band is wound and locked by the locking means (not shown) as described above, it can be used for hemostasis. When hemostasis is completed, the pad 1 may be peeled off and discarded. If a new pad is attached to the plate 20 of the pressing portion 9, it can be reused in the same manner.

In FIG. 9, the plate-like body 10 is provided with holes 23 so that the band-like binding band 8 can be inserted and the position of the plate-like body 10 can be changed with respect to the binding band 8. There is. The plate-shaped body 10 is provided with a recessed portion 14. A convex portion 24 is provided on a part of the pad 1, and the convex portion 24
Is loosely fitted in the recess 14. The pad 1 is pressed against the puncture portion, and the concave portion 14 of the plate-shaped body 10 is aligned with the convex portion 24 of the pad, and then the binding band 8 is wrapped and pressed to stop the bleeding. When hemostasis is completed, the binding band 8 is loosened and removed, so that the convex portion 24 becomes the concave portion 14
Since it is loosely fitted to the pad, it can be removed naturally without touching the pad.

Referring to FIG. The pad 1 is fixed to one surface of the plate-shaped body 10, and the adhesive layer 32 is provided on the other surface. This pad 1 is temporarily fixed to the binding band 8 by the adhesive layer 32 of the plate-shaped body 10. When the hemostasis is completed, the pad 1 may be removed together with the plate-shaped body 10 and discarded. You can use it again. It is also possible to temporarily fix the pad without the plate-like member to the binding band with an adhesive.

In the one shown in FIG. 11, the central portion is thickened by a plastic such as polypropylene or polyethylene to form a pressing portion 9 and the both sides are gradually thinned to form an integral binding band 8. Proper locking means is provided at the end. The pressure-sensitive adhesive layer 22 provided on one surface of the pad 1 can be attached to the pressing portion 9 for use.
It can be used again by replacing the pad 1.

In FIGS. 12 to 13, the center portion is thinned by a plastic having a hinge characteristic such as polypropylene or polyethylene to form the hinge portion 25 so that the hinge portion 25 can be bent. The band 27 is attached to the binding band 8. The plate 26 is provided with locking protrusions 28 on both sides of the hinge 25 so that the pad 1 can be gripped and locked. When hemostasis is completed, bend the hinge part 25 to the side opposite to the pad,
The used pad 1 can be discarded. This plate 2
The stopper 6 prevents the pad 1 from being bent beyond a certain angle in the direction in which the pad 1 is sandwiched.

In the above case, as shown in FIG. 2, when the plate-like body 10 of the pressing portion is located slightly inward with the spaces 30 from both side edges extending in the longitudinal direction of the binding band 8,
When this binding band is wound, both side edges of the binding band are bent to cover both sides of the plate-like body 10, preventing the pressing plate from shifting in the width direction of the base material and enabling more stable pressing.

Further, in the case of wrapping around the wrist as described above, if the pressing portion 9 is larger than the pad, a large portion of the skin surface is not tightened by the binding band, so that the radial artery punctured by the wrist 37 is pierced. Less likely to interfere with blood circulation in ulnar arteries and veins other than. Therefore, it is possible to press the puncture portion appropriately and stop the bleeding without causing cyanosis or the like. If the pressing plate is bent when this hemostasis is performed, the pressing action of the pad may become stronger due to the restoring function of the pressing plate.

Although hemostasis for the arterial tube has been mainly described above, for blood sampling, infusion, blood transfusion, artificial dialysis, etc., an intravenous needle is pierced through the skin surface with an injection needle, a catheter, a medical tube or the like. Is going. In these cases, after pulling out the injection needle, etc., bleeding from the puncture part of the vein tube is similar,
He / she presses absorbent cotton or gauze strongly with a finger and presses this absorbent cotton with an adhesive tape or an elastic band to stop bleeding. However, in order to stop the bleeding in this way, it is necessary to hold it firmly for more than ten minutes with a finger or the above-mentioned pressing tool, and it is troublesome and if you do not press it with chitin, subcutaneous bleeding, Blood oozing out from the puncture hole on the skin surface is not preferable because it contaminates clothes. In addition, depending on the patient, it may not be possible to perform the pressing action with the finger or the like.

When the injection needle or the like is thin, the hole of the puncture portion for the blood vessel is also small, and hemostasis can be relatively easily stopped for the intravenous line. However, in the case of a thick injection needle or the like, the hole becomes large and the amount of blood that bleeds increases, so that it is difficult to stop the bleeding. However, according to the present invention described above, since hemostasis of the artery can be performed as described above, even when blood is collected or transfused using a thick needle such as a 16-18 gauge, it is usually In some cases, the vein does not require as much compressive force as it does to the artery, so that hemostasis can be reliably performed according to arterial hemostasis.
Further, naturally, hemostasis can be more easily performed when a thin needle is used.

[0032]

INDUSTRIAL APPLICABILITY As described above, the present invention can surely stop bleeding even in a puncture hole for an arterial canal, and in addition to the above-described radial artery, the ulnar artery, the dorsalis pedis artery and the like near the bone. If it is used for the located artery, hemostasis can be effectively performed, and further, hemostasis for the femoral artery is also effective. Further, similarly to the vein, effective hemostasis can be performed on the vein as well. Further, this is easy to operate in use, has a simple structure, and can be reused by replacing the pad, so that the amount of dust is reduced and it is economical.
