Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to absorbing blood bleeding during a surgical operation so that the operation can be performed smoothly.
Further, the present invention relates to a blood absorbing cloth used for accurately grasping the amount of bleeding.

[0002]

2. Description of the Related Art In an invasive surgical operation, an operator conventionally wipes blood bleeding at the time of operation with a sailose having excellent water absorbency, for example, using cotton gauze. While performing the surgery, secure the field of view. In this case, the bleeding is continuous, and the attending nurse constantly works using gauze, but because the blood absorption capacity of the gauze is limited, surgery is performed while changing the gauze very frequently. I have. Although such work is customarily performed, it is very complicated, especially in the case of an operation with a large amount of bleeding, the amount of gauze to be used is enormous, and the simplification is safe and smooth. Has been awaited at the surgical site to perform the procedure.

[0003] Further, the amount of bleeding is measured during surgery, and the necessity of blood transfusion and the amount of blood transfusion must be immediately determined and treated at an operation site where the amount of blood transfusion is determined by the weight of gauze containing a large amount of blood. Measuring is, of course, complicated,
From the viewpoint of measurement accuracy, it is necessary to introduce a tool that can more easily treat bleeding and accurately grasp the amount of bleeding. In fact, it is a fact that the user is accustomed to the inconvenience and continues to perform complicated work as it is.

[0004] Here, if a device that has excellent blood absorbability and can absorb blood promptly is introduced instead of the gauze conventionally used, the operation can be performed extremely smoothly.
The amount of blood bleeding can be measured quickly, which makes it possible to improve the efficiency of the operation extremely well, and it is indispensable for patients to have a positive effect on the post-operative course, which will greatly contribute to the overall medical practice You can do it.

[0005]

Means for Solving the Problems The inventor of the present invention has studied the selection of a material that absorbs blood quickly and is harmless to the human body, and has worked hard to apply it to medical treatment. As a result of intensive studies to prepare a blood-absorbing cloth capable of quickly and sufficiently absorbing the bleeding blood to widen the operation field and perform the operation more smoothly, the present invention has been achieved.

The present invention is a blood-absorbing cloth for absorbing blood bleeding during surgery, characterized in that the blood-absorbing speed is extremely high.

Further, the present invention is a blood-absorbing cloth for absorbing blood bleeding during an operation, characterized in that the blood-absorbing amount is very large.

[0008] Further, the present invention is characterized in that the blood absorbing cloth includes a polymer absorbent. Further, the present invention is characterized in that the polymer absorbent included in the blood absorbing cloth is in the form of powder, granule, flake, cloth or plate.

[0009] Further, the polymer absorber is powdery, granular,
Alternatively, in the case of a flake shape, the contact area between blood and the polymer absorber increases, and the blood absorption rate increases accordingly. Therefore, the form of the polymer absorber is important.

[0010] In addition, when the polymer absorber is in the form of a cloth or a plate, it preferably has a fibril structure such as a nonwoven fabric in order to increase the contact surface with blood. When the polymer absorber is in the form of a powder, the outer diameter is preferably 0.01 to 3.0 mm, more preferably 0.05 to 1.0 mm, and even more preferably 0.1 to 0.5 mm. This outer diameter is 0.0
If it is smaller than 1, the polymer absorber may leak out of the fiber aggregate covering the polymer absorber, and a bad influence on the living body may be concerned. If it is larger than 3.0 mm, the particles absorb blood and swell. The size of the blood absorbing cloth is excessively large, the blood absorbing cloth is not smoothly moved when the cloth is taken out, and the blood absorbing performance is reduced due to a relative decrease in the contact surface with the blood. The polymer absorber may be one in which fine particles in a powder form associate with each other to form granules, and in this case, the absorption performance of blood does not change,
Moreover, the size of the granules reduces the risk of leakage from the covering fiber assembly. In this case, the preferred size of the granules is, as an average outer diameter, preferably 0.05 to 3.0 mm, more preferably 0.1 to 2.0 mm, and further preferably 0.1 to 0.5 mm.

When the blood-absorbing cloth is a non-woven fabric, the fibrils preferably have a diameter of 0.001 to 0.3 mm.

Further, in the present invention, the above-mentioned polymer absorbent is wetted by blood and blood easily penetrates, and the polymer absorbent is covered with a fiber or a fiber aggregate such as cloth which does not pass through. It is characterized by having.

[0013] Further, the present invention provides the above-mentioned polymer absorbent, which is covered with a fiber aggregate such as a fiber or cloth through which the polymer absorbent easily penetrates the blood and easily penetrates the blood, but cannot pass through. The unevenness is prevented by means such as quilting so that the applied polymer absorber is uniformly arranged as a whole in the coating.

Further, in the present invention, the polymer absorbent is covered with a fiber assembly such as a cloth which is easily wetted by blood and easily penetrates blood but does not pass through the polymer absorbent. It is characterized in that the polymer absorber is disposed therein and is arranged in a multilayer shape.

Further, the present invention relates to the blood absorbing cloth of the present invention for absorbing blood bleeding during surgery, wherein a string-shaped or tape-shaped handle is attached to a part of the blood absorbing cloth as desired. It is assumed that.

As the polymer blood absorber used in the present invention, a water-absorbing polymer substance is used. Highly water-absorbing polymer substances are well known, and have been put to practical use as sanitary products for women, diapers for infants or diapers for incontinence of the elderly, etc. There is no example. For example, if a woman's sanitary product is used as it is for a surgical operation, the amount of bleeding from the surgical operation is large, and it cannot be used because of its lack of capacity to absorb blood .

[0017] The use at the operation site should be sterilizable, and the high molecular substance used should not leak to the operation site. In the case of using gauze, which has been used for conventional feminine hygiene products, there is insufficient consideration for leakage of a water-absorbing substance, and no measures have been taken.

The present invention is directed to any such medical,
In particular, the present inventors have studied the development of a blood-absorbing cloth that satisfies all the strict requirements for surgery, and have reached the present invention.

As the polymer blood absorber of the present invention, a water-absorbing polymer substance is widely used. Blood comprises so-called blood cell components such as red blood cells, white blood cells, and plasma plates, plasma containing nutrients such as proteins represented by albumin, and water. When blood containing these components comes into contact with a water-absorbing polymer absorber, water is first absorbed and blood cell components, proteins, and the like in the blood precipitate or deposit on the surface of the polymer absorber. This is as if the blood had been adsorbed. In order to sufficiently exhibit this property, the fiber covering the polymer absorbent, the cloth or the fiber aggregate of the cloth-like body must have a gap through which plasma such as blood cell components and albumin can easily pass. In addition, the polymer absorbent that has absorbed blood or blood component water usually becomes loose and swelled particles when it absorbs a large amount of water, and easily loses its shape as it is, and cannot maintain a fixed shape.

Since the blood-absorbing cloth of the present invention is mainly used at the time of a surgical operation, a polymer absorbent for absorbing blood bleeding at the time of a surgical operation leaks outside from the fiber assembly of the cloth or cloth. In such a case, the leaked residue of the polymer absorber remains in the living body and becomes serious. Therefore, the cloth or cloth must never leak out of the polymer absorber. In other words, the cloth or cloth used in the present invention cannot be practical unless it has a property of allowing blood to pass through without any problem and never passing through the polymer absorbent.

Further, as a blood absorbing capacity, 20 ml or more within 1 minute, preferably 50 ml or more within 1 minute, more preferably 100 ml or more within 1 minute, more preferably 200 ml or less within 1 minute per blood absorbing cloth. It is desirable to have the ability to absorb more than 300 milliliters of blood within a minute, more preferably less than 1 minute. If the blood absorption rate is less than 20 milliliters within one minute, the operation is hindered, which is a problem from a practical viewpoint.

Examples of the material of the polymer absorbent include carboxymethyl serose, polyacrylic acid, sodium polyacrylate, polymethacrylic acid, polysodium methacrylate,
Diacetone acrylamide polymer, polyacrylamide, starch-acrylonitrile graft copolymer and the like can be used. From the viewpoint of blood absorption capacity and safety, a substance containing sodium polyacrylate is most suitable. The form may be a powder, a granule, a flake, a fibrillated cloth, for example, a non-woven fabric, or a powder, which is dispersed and entangled in a cloth, for example, a woven fabric, a knitted fabric, or a non-woven fabric. May be.

The cloth or cloth-like fiber aggregate covering the material of the polymer absorbent may be made of a hydrophilic cellulosic material, for example, cellulose as a constituent component, even from the viewpoint of blood passage. Needless to say, synthetic fiber, Bemberg (trademark) produced by the copper ammonium method, cotton with a gauze material, etc. are preferred, but it is not always necessary to have such a high degree of hydrophilicity. If it does not have repelling hydrophobicity, it may be nylon or nylon fiber or polyester fiber made of polyethylene terephthalate, for example, as long as it is wet with blood and allows blood to pass through without resistance.

For example, even a polyester fiber made of polyethylene terephthalate, which is considered to be relatively hydrophobic, may have a function of sucking blood by capillary action using a hollow fiber. In short, any material can be used as long as it is wet with blood and allows blood to pass through without resistance. When used for surgery,
The fiber used in the present invention, the fiber aggregate of the cloth or the cloth-like body is not woven from short fibers but is woven or woven from a material of long fibers, or a non-woven fabric so that no fluff or the like remains after the operation. Desirably, even a woven fabric made of short fibers of cotton or synthetic fiber or a knitted fabric can be used as long as a fine structure is formed. Alternatively, hydrophilicity may be imparted by a known hydrophilic treatment, for example, treatment with ethylene glycol, polyethylene glycol, alcohol, or the like. In this case, glycerin treatment, which is one of the biological components having no problem for the living body, is most preferable.

Since the blood-absorbing cloth according to the present invention is required to be thin and rich in blood-absorbing properties, it is necessary to uniformly dispose the polymer absorbent on the cloth. For this purpose, it is preferable to apply quilting to the cloth-like body containing the polymer absorber to maintain uniformity. This quilting may be sewn in,
Means for heat fusion may be used.

In order to make the blood-absorbing cloth of the present invention thinner and to enhance the blood-absorbing ability, a high-molecular-weight absorbent may be provided in multiple layers, and a cloth may be provided between each layer as required. In addition, a string-shaped or tape-shaped handle is arranged on a part of the blood-absorbing cloth of the present invention, preferably on the end or edge of the blood-absorbing cloth. It is preferable to provide a stool for inserting the blood absorbing cloth into a predetermined place. By doing so, the time and effort for replacing the conventional gauze is greatly simplified, and the accuracy of measuring the amount of bleeding is greatly improved.

The shape of the blood-absorbing cloth used in the present invention can take various shapes such as a square, a rectangle, an ellipse, and a circle. The most preferred shape does not depend on the surgical site, but a rectangular shape is most convenient.

The size is 5 cm in the long axis of the rectangle.
To 30 cm, preferably 8 cm to 20 cm,
More preferably, it is 10 cm to 16 cm. If the major axis is larger than 30 cm, it is difficult to insert into the surgical site,
If it is smaller than 5 cm, the absorption capacity of blood is insufficient.

The thickness of the blood-absorbing cloth used in the present invention is preferably 0.1 mm or more and 10 mm or less before use, more preferably 0.3 mm or more and 8 mm or less, and still more preferably 0.5 mm or more and 5 mm or less. Is good.

If the thickness of the blood-absorbing cloth is 0.1 mm or less, the blood-absorbing ability is insufficient, and the blood-absorbing cloth needs to be replaced many times.
The operation is complicated, and the effect of the present invention is reduced by half.
On the other hand, if the thickness exceeds 10 mm, it becomes difficult to perform the operation, and smooth operation is hindered.

In addition, the blood absorbing cloth of the present invention, when absorbing blood, increases its thickness due to the absorbed blood.
Its maximum thickness is preferably 3 cm or less. Of course, the thickness of the absorbed blood is also a function of the time of contact with the blood, and the blood absorbing cloth may be replaced as appropriate at the discretion of a doctor or nurse. Can determine the usefulness in advance.

In other words, FIGS. 2 (A), (B),
As shown in (C), the ratio between the thickness d of the blood-absorbing cloth 1 according to the present invention at the time of drying (before use) and the thickness D after swelling by contact with water (hereinafter referred to as wet / dry swelling ratio). ), The value of D / d is at least 2 or more, preferably 3 or more, and the preferable range is that D / d is 2 to 100, preferably 3 to 80.
It is good to be between. If this value exceeds 100, the blood-absorbing cloth at the time of swelling becomes too thick and cannot be quickly removed from the place of treatment. Actually, the operator who concentrates on all the nerves for the operation does not pay attention to this point, and it is expected that the replacement of the greatly swollen blood absorbing cloth will be hindered. Therefore, it must be said that the means for controlling this excessive swelling is important from the viewpoint of practical use.

The best way to control this swelling at some point is to quilt the absorbent cloth as described above.

Here, a method for measuring the thickness of the blood absorbing cloth of the present invention will be described. All the thickness measurements described above are by this method. That is, in measuring the thickness, two acrylic plates (made of polymethyl methacrylate) having a thickness of about 2 mm and having substantially the same area as the measured blood-absorbing cloth are prepared, and the blood-absorbing cloth to be measured is sandwiched between them. After the above, the gap between the acrylic plates is measured. In this way, the thickness can be measured with good reproducibility even if the thickness changes depending on the degree of pressing, such as gauze (see FIG. 2C). Reference numeral 9 denotes an acrylic plate used for measurement.

Although the above-described blood absorbing cloth has been described assuming a flat-plate shape, it is not necessarily required to have a flat-plate shape. For treatment of narrow cavities or elongated bleeding sites,
A large-area, flat blood-absorbing cloth is rather powerless. In this case, the blood-absorbing cloth is desirably a flexible (flexible and elastic to some extent) rod shape, and the blood-absorbing cloth of the present invention is, in addition to the flat-plate-shaped cloth already described in detail,
Various variations (deformations) such as a rod-shaped object, a long and flat ruler-shaped object, and a tapered and flat triangular object are conceivable, and it goes without saying that these are also included in the present invention.

[0036]

The present invention provides a blood-absorbing cloth which is used at the time of a surgical operation and absorbs bleeding blood quickly and in a large amount. The operation can be performed smoothly and the amount of the bleeding can be accurately grasped. And greatly contribute to medical care.

Hereinafter, the present invention will be described in more detail with reference to several examples. It should be noted that these examples are for illustrative purposes only, and do not limit the scope of the present invention in any way.

[0038]

Example 1 Approximately 1 gram of spherical sodium polyacrylate having an average outer diameter of 0.3 mm was uniformly distributed between two cloths (9 cm × 6 cm) of a woven fabric of cellulose long fibers (manufactured by Bemberg (trademark)). And the edge of the cloth was sewn to produce a rectangular thin cloth-like sample containing the spherical sodium polyacrylate therein. Quilting was performed by sewing at intervals of about 15 mm so that the spherical sodium polyacrylate inside was not biased (see FIG. 1A). As a result, the spherical sodium polyacrylate was not biased during handling. The thickness of this sample was about 0.7 mm (see FIG. 2A). In these drawings, 1 is a blood absorbing cloth main body, 3 is a cloth (disposed on the front and back of the blood absorbing cloth), 5 is quilting by sewing, and 7 is a handle.

Two hundred milliliters of human blood containing heparin was collected in a tray, and the cloth containing the spherical sodium polyacrylate was placed. After 30 seconds, the blood was completely absorbed by the cloth. The sample that absorbed the blood swelled (Fig. 2
(B)), the maximum thickness was about 8 mm, but the whole was flexible.

The spherical sodium polyacrylate that has absorbed blood has increased in volume due to swelling, but the spherical bodies do not stick together and are displaced with each other, so that they are rich in deformability, and the cloth is flexible and can be removed. It was easy. In this example, (wet / dry swelling ratio) D / d of the blood absorbing cloth measured using water
The ratio was 15.2.

The same reference numerals are given to the same names.

When 100 ml of fresh blood to which a small amount of heparin was added to prevent coagulation was placed in a tray, and the above-mentioned sewing cloth was placed on the fresh blood, the blood was immediately absorbed, and after 22 seconds, the blood was completely removed. Absorbed.

In this example, the (wet / dry swelling ratio) D / d ratio of the blood absorbing cloth was 8.3. In a blood-absorbing cloth that was not quilted vertically and horizontally under exactly the same conditions, this D
The / d ratio was 41.

[0044]

Example 3 A string of polyester fiber and a tape-like cloth made of cotton were attached to the end of the blood-absorbing cloth prepared in Example 1 and the edge of the blood-absorbing cloth prepared in Example 2, respectively, as handles. (See FIGS. 1A and 1B). Raise the blood-absorbing cloth, which has increased its thickness by absorbing blood,
It was confirmed that insertion, removal or replacement of this blood absorbing cloth was easy.

[0045]

Example 4 Polyester long fiber woven fabric (6 cm × 6 c)
During m), a non-woven fabric (4 cm × 4 cm, thickness 1 mm) made of sodium polyacrylate was inserted, and the periphery of the cloth was completely sewn with a sewing machine. The total thickness including the nonwoven fabric sheet of sodium polyacrylate is 1.4 mm.

200 ml of human blood containing heparin was collected in a tray, and a cloth body having the above-mentioned non-woven fabric of sodium polyacrylate was placed in the tray containing blood. After 20 seconds, the blood in the tray was completely absorbed by the cloth. The cloth that absorbed the blood swelled to a thickness of about 15 mm, but was entirely flexible. When the cloth was removed, almost no blood remained in the tray. In this example, the (wet / dry swelling ratio) D / d ratio of the blood absorbing cloth measured using water is 1
4.7.

[0047]

Embodiment 5 Nylon long fiber woven fabric (6 cm × 6 c)
m) and a nonwoven fabric (4 cm × 4 cm, thickness 2.2 mm) made of sodium polyacrylate was used. In this example, the blood in the tray was completely absorbed in 15 seconds. In this example, the (wet / dry swelling ratio) D / d ratio of the blood-absorbing cloth measured using water was 19.4. When the (wet / dry swelling ratio) D / d ratio of the same blood absorbing cloth except that no quilting was performed was measured, this value was 2
It became 6.

[0048]

Example 6 Six pieces of cloth (9 cm × 6 cm) of cellulose long fiber woven fabric (manufactured by Bemberg (trademark)) were prepared, and a spherical polyacrylic having an average outer diameter of 0.3 mm was placed on two of them. Approximately 1 g of acid soda is evenly distributed, and one piece of the cloth is placed thereon, and about 1 g of the spherical sodium polyacrylate is further uniformly distributed thereon. A rectangular blood-absorbing cloth comprising a triple-layered fibrous structure in which a double-layered cloth is placed, two upper and lower surfaces are stacked, and the middle is a single partition, and the edges are sewn to include three layers of sodium polyacrylate. made. In this example, quilting was applied at intervals of 2 cm, and a treatment for keeping the distribution of sodium polyacrylate uniform was performed. The edge of the cloth was sewn to produce a rectangular thin cloth-like sample containing the spherical sodium polyacrylate particles therein.

As a result, the spherical sodium polyacrylate was not biased during handling by the above quilting. The thickness of this blood absorbing cloth before use was 2.1 mm.

Three hundred milliliters of human blood containing heparin was collected in a tray, and the above-mentioned cloth containing spherical sodium polyacrylate was placed. After 20 seconds, the blood was completely absorbed by the cloth. The cloth that absorbed the blood swelled to a thickness of about 11 mm, but was soft overall. Spherical sodium polyacrylate that has absorbed blood has increased in volume due to swelling, but the spherical bodies do not stick to each other, causing misalignment with each other, and are highly deformable, and the cloth is flexible and easy to remove. Was. In this example, (wet /
(Dry swelling ratio) D / d ratio was 14.4.

When the (wet / dry swelling ratio) D / d ratio of the same blood absorbing cloth was measured except that no quilting was performed, this value was 40.8.

[0052]

Example 7 Colorless cotton woven bags (8 cm
× 10 cm), a nonwoven fabric (8 cm × 1 cm, thickness 0.6 mm) made of sodium polyacrylate was inserted, and the opening was sewn. In this example, the sodium polyacrylate is a non-woven fabric and an integral cloth, so there is no bias and no quilting is required. The thickness of this cloth was about 1.2 mm.

200 ml of human blood containing heparin was collected in a tray, and a cotton sack containing the above-mentioned nonwoven fabric of sodium polyacrylate was placed. After 25 seconds, the blood was completely absorbed by the cloth. The cloth that absorbs blood is about 7m thick
m, but the whole was soft.

Although the volume of the spherical sodium polyacrylate that absorbed blood increased due to swelling, the cloth that absorbed blood was soft and easy to remove. In this example,
The D / d ratio (wet / dry swelling ratio) of the blood absorbing cloth was 9.8.

[0055]

Example 8 Double sailose nonwoven fabric (8 cm × 1
2 cm), about 1 g of spherical sodium polyacrylate having an average outer diameter of 0.2 mm is evenly placed thereon, and one sheet of the nonwoven fabric is placed thereon, and about 1 g of the spherical sodium polyacrylate is placed thereon. Is distributed uniformly, and further, a non-woven fabric is placed on it, and about 1 gram of sodium polyacrylate is evenly distributed and distributed thereon. Finally, a two-ply non-woven fabric is placed. A nonwoven fabric having a triple structure with one partition in the middle was formed, and the edges thereof were sewn to produce a rectangular blood-absorbing cloth containing three layers of sodium polyacrylate.

In this example, the particles of sodium polyacrylate were not entangled in the gaps of the nonwoven fabric, so that the particles of sodium polyacrylate were not biased, and quilting for uniform distribution was unnecessary. The edge of the cloth was sewn to produce a rectangular thin cloth-like sample containing the spherical sodium polyacrylate particles therein. The thickness of this sample is 2.3
mm.

340 ml of human blood containing heparin was collected in a tray, and a cotton cloth bag containing the above-mentioned nonwoven fabric of sodium polyacrylate was placed. After 30 seconds, the blood was completely absorbed by the cloth. The cloth that has absorbed the blood has a thickness of about 22
mm, but the whole was soft.

The spherical sodium polyacrylate that absorbed blood increased in volume due to swelling, but the cloth that absorbed blood was soft and easy to remove. In this example,
The D / d ratio (wet / dry swelling ratio) of the blood absorbing cloth was 29.8.
