Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube, a catheter, which is inserted into the human body through an opening in the human body such as the nasal cavity,
The present invention relates to a tape for fixing and holding a cable in an opening of a human body.

[0002]

2. Description of the Related Art In the medical field, in order to cope with various diseases, a tube, a catheter, a cable or the like (hereinafter referred to as a tube) is inserted from the nasal cavity. For example, gastric tube for injecting water or drug into the stomach or guiding and excreting gastric contents out of the body, feeding tube for nutritional management for diseases where it is difficult to take food, intestinal contents stored in the small intestine Ileus tube used for drainage of blood, S-B (Zengstaken-Blakemore) tube used for pressure hemostasis when esophageal varices are ruptured, ENBD (endoscopic transnasal biliary drainage) used for draining bile And so on. This type of nasal tube is often left in place for several hours to several days for the intended treatment, but during that period, the nasal tube may fall out of the patient or, conversely, be inserted excessively inside. Be sure to hold the tube in a specific position to prevent medically dangerous situations such as
Must be fixed.

In addition to the nasal tube, there are various tubes inserted into the human body opening. For example, an endotracheal tube inserted from the mouth for the purpose of securing the trachea, artificial respiration, drug administration, a central venous catheter inserted under the clavicle for nutritional supplementation by the venous route, a thoracic cavity inserted under the sternum for draining blood and lymph. Drainage, abdominal drainage that is inserted from the abdomen to drain exudate in the body, a blood transfusion tube that is inserted into the arm for blood transfusion, and a urinary catheter that is inserted into the thigh to prevent urinary tract injury are examples. Similar to the nasal tube, these tubes also need to be fixed and held to prevent the tubes from falling off and overinserting.

There are various types of tube fixing methods of this type. One of them is to cut a roll-shaped adhesive tape for general medical use into a required length and process it into an appropriate shape to fix the tube to the skin of the patient by adhesive. In this method, it is necessary to cut the tape to the required length each time, the work is complicated, and it is easily influenced by the ideas and tastes of each doctor and nurse, and it has been established as a reliable fixing method. This kind of work is a heavy burden for busy doctors and nurses, and is likely to cause malpractice. Therefore, various dedicated tube fixtures have been devised.

[0005] One of them is to form a nose sticking part and a tube fixing part which are integrated with a special tape which is precut so as to easily fix a nasal tube, and the nose sticking part is fixed to the nose to form a tube. The tube is fixed at the fixing portion (US Pat. No. 5833663). With this tube holder, once the tube fixing part is attached to the tube, it is difficult to remove it from the tube, so it is impossible to re-fix the tube or adjust the position, and the tube fixing part is symmetrical from the center line to the left and right. When the tape is formed and wound around the tube, the adhesive surfaces of the tube fixing part often overlap each other, and even if the adhesive surfaces do not overlap, it is difficult to peel off if the adhesive surface of the tape sticks to the surface of the tape, and as a whole it is extremely It is difficult to handle and the tape cannot be applied neatly.

There is also known a medical clamp for fixing a tube on a fixing portion having an adhesive layer on the skin contact side and a surface fastener on the non-skin contact side by using the surface fastener (Japanese Patent Publication No. 63-501477). Issue). This clamp is composed of multiple parts, and it is easy to remove the tube because it uses a hook-and-loop fastener, but the tube cannot be securely fixed due to poor adhesion to the tube, and the tube is too thick to be attached. It is uncomfortable, and it has a drawback that it is economical because it is expensive because it should be thrown away in order to maintain cleanliness and eliminate infectious diseases.

Further, there is also known a nasal tube holding device including a pad which is adhesively fixed to the upper part of the nose and a molded member which is fixed to the pad and has a plurality of elements for sandwiching the tube (Japanese Patent Publication No. 6- 26577 publication). This holder can accommodate tubes with different diameters and can adjust the position and re-fixation of the tubes, but since the molded member is used, it is expensive, bulky and uncomfortable when mounted, Since it is just under the nose, it may come into contact with the skin and rub against it, and since it is not a single material, the manufacturing process is complicated, and it is necessary to separate waste when disposing of it after use.

[0008]

An object of the present invention is that the structure is simple, it does not rub against the skin, it can be easily peeled off from the tube when the tube position is adjusted or replaced, and it is easy to operate and wear. Even if it does not feel uncomfortable, it is to provide an orthosis for tube fixing.

[0009]

In order to solve the above-mentioned problems, in the present invention, a flexible sheet-like base material is used, and the base material is a human body fixing portion, a tube fixing portion, and a back surface.
Equipped with an adhesive layer and a release liner that covers the adhesive layer, fixing it to the human body
And the tube fixing part are connected to each other in the same plane on the base material via the connecting part.
And the tube fixing part is connected to the human body fixing part and the connecting part.
At least one portion is formed so as to be able to be wound around the tube so as to project to one side in the axial direction of the base material passing through the tube fixing portion .

It is preferable that the tube fixing portion is formed such that the front surface and the back surface of the adhesive layer are re-adhesive and re-peelable.

The tube fixing portion is a body fixing portion, a connecting portion and a cheek.
At different positions in the axial direction of the substrate passing through the tube fixing portion, a plurality of portions that project on one side on the same side or alternately on one side on the opposite side and can be wound around the tube can be provided.

In the present invention, re-peeling is based on the definition of JIS (Japanese Industrial Standards), and when peeling off the adhesive layer of the substrate adhered to the adherend, the adhesive is removed without damaging the substrate. It means the property that it can be peeled off without leaving it on the adherend.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described with reference to the examples shown in the drawings.

FIG. 1 shows an embodiment of a tape for fixing a nasal tube according to the present invention, in which a is a front view, b is a side view, c is an explanatory view of a mounted state, and b is for easy understanding of the drawing. The dimension in the thickness direction is shown enlarged.

Reference numeral 1 is a base material formed of a flexible sheet, and an adhesive layer 2 is provided on the back surface thereof, and the adhesive layer 2 is covered with a release liner 3 for protection during storage. It is divided at 4 points so that the release liner can be easily peeled off. The base material 1 and the adhesive layer 2 are composed of a nose fixing part 5 located at the upper part of the figure and a tube fixing part 6 located at the lower part of the figure.
When more is integrally formed on the connecting portion 7 for connecting the two parts. The nose fixing part 5 spreads symmetrically and is formed so that it can be attached to the upper part of the nose, and the tube fixing part 6 is laterally only on one side in the direction of the axis 8 of the base material, in the example of the figure, the left side only. It has a portion 9 which has a length which can be wound around the tube to be fixed and which is largely projected.

Next, a method of mounting the fixing tape on the nasal tube will be described. As shown in FIG. 1c, the tube 1
0 is inserted from the nose 12 of the nose 11 to a predetermined position, and the axis 8
The nose fixing part 5 is attached on the nose 11 in such a positional relationship that (FIG. 1 a) is located on the bridge of the nose 11 of the patient, and in this state, the part 9 protruding to the left side of the tube fixing part 6 is attached to the tube 10. Adhesive layer 2 on the back of the tube fixing part 6 wrapped around
(Fig. 1b) sticks together. At this time, the tube fixing part 6
Can be wrapped around the same location on the tube 10 in layers to overlap and secure the tube 10 in place. In this case, the tube fixing portion 6 is once adhesively fixed between the front surface and the back surface adhesive layer, and between the back surface adhesive layer of the tube fixing portion 6 and the surface of the tube 10, and then peeled off. It is easy to adjust the mutual fixing position of the tube by adjusting the mutual position, re-adhesion and re-peeling.

The base material is formed into a sheet and has a thickness of 0.01 to
It is set to 4 mm, preferably 0.1 to 2.5 mm. If it is thinner than 0.01 mm, curling occurs and it is difficult to handle, and it is easy to tear when peeling,
Further, it does not have sufficient strength to withstand repeated peeling, and it is difficult to obtain sufficient fixing force for the tube. If it is thicker than 4 mm, it will be hard and will feel uncomfortable when attached, and it will not follow the curved surface well. The width of the base material is large enough to straddle both sides of the nose bridge of the nose in the nose fixing portion 5, and the width of the connecting portion 7 is preferably slightly shorter than the peripheral length of the tube to be fixed. The length of the protrusion depends on the thickness of the tube, but the maximum length from the axis perpendicular to the axis to the end of the tube fixing portion is set to about 10 to 45 mm. It is preferably 15 to 25 mm. If it is less than 10 mm, when using a tube with a relatively large diameter among the general tubes applied to the nose, the part that fixes the tube is just around the outer circumference of the tube, Is a range in which the tape can be fixed without any problem, but the feeling of security in fixing is slightly inferior to the range of the preferable tape length. In addition, the part that can be held by the hand is shortened, making it difficult to operate. If it is longer than 45 mm, a large surplus portion beyond the outer circumference of the tube will appear, so the outer circumference of the tube will be excessively fixed, which will be troublesome in operation.

The following materials can be used as the base material.

Material A: A single sheet or a laminate of the following elastic polymers, particularly thermoplastic polymers, which are produced alone or by appropriately mixing them: acrylic type, polyamide type, polycarbonate type, polyester type, polystyrene type, olefin type ( E.g. poly
1-butene, polyethylene, polypropylene), olefin copolymer (eg EVA (ethylene vinyl acetate), EEA (ethylene ethyl acrylate copolymer), E
MA (ethylene methyl acrylate copolymer), EMMA (ethylene methyl methacrylate copolymer), EMAA (ethylene methacrylic acid copolymer), polysulfone, polytetrafluoroethylene, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polyvinyl fluoride Vinylidene chloride Add pigments, heat stabilizers, light stabilizers, UV absorbers, inorganic or organic slip agents as needed.

Materials B: Woven fabrics, knitted fabrics, non-woven fabrics made of the following materials singly or in an appropriate mixture: Natural fibers (cotton, wool, silk, hemp) Chemical fibers (rayon, cupra, polynosic, acetate, triacetate, professional Mix, polyethylene,
(Polypropylene, polyamide, polyester, polyacrylonitrile, vinylon, polyvinyl chloride, vinylidene, polyurethane)

Material C: Foam material produced by mixing the following materials alone or in an appropriate mixture: Polyurethane foam, rubber foam, polyethylene foam, polypropylene foam, polyethylene and ethylene vinyl acetate copolymer Mixed with polyolefin resin foam, polyvinyl chloride foam, and polystyrene foam, both closed and open cells are possible.

In order to make the surface of the tube fixing portion of the base material, that is, the surface of the tube fixing portion facing the adhesive layer of the tube fixing portion when wound around the tube, re-adhesive and re-peelable, Although it is advantageous to make the surface of the substrate have low adhesion, there are various means for doing so. The first method is a physical method, in which minute holes are provided in the substrate to reduce the contact area with the pressure-sensitive adhesive layer. This method can be applied to the above-mentioned material A to be used, and the porosity thereof is 15 to 70%, and it can be formed by a usual perforation method. If the porosity exceeds 70%, the strength of the base material is lowered, the peeling cannot be endured repeatedly, and sufficient adhesive force with the adhesive layer at the tube fixing portion cannot be obtained. If the porosity is less than 15%, the adhesion area increases, and it becomes difficult to remove the surface of the tube fixing portion and the adhesive layer again. The shape of the aperture is arbitrary such as a square, a rectangle, a circle, an oval, a rhombus, and a triangle, and may be symmetric or asymmetric. The second method is a chemical method in which a base material is treated with a release agent such as silicone, long-chain alkyl polymer, polyolefin, alkyd resin, or fluorine compound. This method can be applied to any of the above-mentioned used material A, used material B, and used material C. The third method is to select and use a substrate having a low surface energy. Specifically, the surface tension is 3.9
Polyethylene, polypropylene, polyvinyl alcohol, etc. can be used as those having a density of x10 ^-2 N / m or less.

Further, when the surface of the base material has low adhesiveness,
It is also possible to use a composite material by laminating the above-mentioned low-adhesive substrate with another non-low-adhesive substrate.
As the usable material, any of the above-mentioned used materials A, B, and C can be used, but it is particularly preferable to stack the used material B on which the low-adhesion treatment is not applied. In that case, the material A used is polyethylene, polyester,
Polypropylene and olefin-based copolymers are suitable, and as the material B to be used, rayon, polyethylene, polypropylene and polyester are particularly preferable. Material B has excellent flexibility and feel when applied, and a combination of perforated material A and material B used and coated with a breathable adhesive makes this tube fixing tape. It can be breathable, and it is difficult for stuffiness and rashes to occur due to the base material. This air permeability has an air permeability defined by JIS P8117 of 120 seconds / 100cc / 645mm ² or less, preferably 30 seconds / 100cc / 645mm ²
The following range is preferable, and if it exceeds 120 seconds, the amount of evaporation to perspiration is small and stuffiness easily occurs. As a method for imparting air permeability to the pressure-sensitive adhesive, a known technique can be used, a method of mixing a substance that vaporizes and foams by drying with the pressure-sensitive adhesive, and drying after coating the pressure-sensitive adhesive, pattern coating or spray coating. A method of mechanically making holes can be used. Other advantages of using such a composite material are as follows. That is,
For example, a low-adhesion base material based on a thermoplastic resin has a property that it is difficult to write characters due to the relationship between the surface smoothness and the surface tension, and it is difficult to write characters on cloths and foams because the surface is soft and rough. By stacking two sheets, the pen tip moves smoothly, the ink is good and the letters can be written clearly and clearly.By writing the type of tube and the insertion date and time on the surface of the base material, medical malpractice can be prevented. Can be prevented. In addition, since the surface of the thin thermoplastic polymer sheet or the non-woven fabric is reinforced, the base material does not curl when it is applied to the skin, and it is easy to handle. Does not cause material destruction.

As the material of the pressure-sensitive adhesive layer, a conventional pressure-sensitive adhesive can be used, and various materials such as rubber-based, acrylic-based, vinyl ether-based, urethane-based and silicone-based materials are available. The thickness of the adhesive layer is 0.01 to 1.5 mm, and the coating weight is 1
It is 0 to 150 g / m ² . Considering the balance of adhesive properties and stability in production, 0.02 to 1.3 mm is preferable, more preferably
It is 0.05 to 0.8 mm. In the above numerical values, the required adhesive strength is often not obtained when it is less than 0.01 mm, and when it exceeds 1.5 mm, it is difficult to manufacture, productivity is reduced, and the cohesive force of the pressure-sensitive adhesive is reduced. There is a possibility that adhesive residue will remain on. It is not always necessary to use the same adhesive on the entire surface of the adhesive layer. For example, different adhesives are used for the adhesive layer corresponding to the human body fixing part and the tube fixing part. It is also possible to select such that the optimum adhesion to the material surface can be obtained.

In addition, as an adhesive layer, the above-mentioned adhesive component,
If a mixture of water-absorbent substances is used, it absorbs these liquids and keeps them at an appropriate humidity against sweat from the skin with the tape attached and exudation of body fluid from the tube insertion part. Can maintain the physiological state of. Specific examples of such an adhesive component include polyisobutylene, polyisoprene, acrylic polymers, styrene / isoprene / styrene block copolymers, polybutadiene, styrene / butadiene / styrene block copolymers, styrene / ethylene / butadiene / Examples thereof include styrene copolymers, natural rubber, silicone-based polymers containing polymethylsiloxane as a main component, polyvinyl ether-based polymers, and the like, and one or more of these can be used. On the other hand, as the water-absorbing substance, sodium carboxymethylcellulose, carboxymethylcellulose calcium, dextrin, gelatin, pectin, locust bean gum, guar gum, karaya gum,
Examples include xanthan gum, sodium alginate, calcium alginate, carrageenan, collagen, and polyvinylpyrrolidone, and one or more of these can be used.

As a method of enabling re-adhesion and re-peeling between the front and back adhesive layers of the tube fixing portion of the substrate, the adhesive layer of the tube fixing portion can be made weakly adhesive. According to this, even if the adhesive layers of the tube fixing portion adhere to each other, they are easily peeled off, which is advantageous. For that purpose, there are the following methods. The first is a method of changing the composition of the pressure-sensitive adhesive, in which an appropriate amount of the tackiness adjusting component is mixed with the pressure-sensitive adhesive. As the adhesion adjusting component, lecithin, zinc naphthalate, calcium naphthalate, copper oleate, surfactant such as oleic acid, dicarboxylic acid, plasticizer such as ester of phosphoric acid, silicone-based, long-chain alkyl-based release agent, Fillers such as silica, alumina, titanium dioxide, calcium carbonate, magnesium carbonate, talc, polyisocyanate compounds,
There are crosslinking agents such as organic peroxides, organic metal salts, metal alcoholates, metal chelate compounds, and polyfunctional compounds. Second
Is a method of coating, which includes a method of reducing the adhesion area by pattern coating, spray coating, etc., a method of reducing the thickness of the coating, and a method of disposing a non-adhesive fiber woven or knitted fabric on the adhesive surface. Thirdly, non-adhesive fiber woven / knitted fabric in the adhesive,
There is a method of arranging a net-like sheet. It should be noted that this method may be used in combination with a method of making the surface of the tube fixing portion have low adhesiveness.

In the present invention, the above-mentioned conditions under which the base material of the tape and its adhesive surface can be re-peeled are various combinations of the above-mentioned materials, and the tape surface and its adhesive layer are bonded together. The peeling adhesive strength at that time was determined based on a value measured by a test method based on JIS Z0237 “180 degree peeling adhesive strength to the back surface”. That is, the surface of the tube fixing tape is bonded to the stainless plate with the adhesive layer, and the tube fixing tape is further bonded with the adhesive layer on the bonded tube fixing tape, and the latter tube is fixed. 180 ° peeling adhesive strength when the tape for tape is continuously peeled off from the surface of the former tube fixing tape at a speed of 300 mm / min.
It should be in the range of 0.5 to 15 N / 25 mm, preferably 1 to 7 N / 25 mm. If this value is lower than 0.5 N / 25 mm, the fixing force of the tube will be weak and it will be difficult to securely fix the tube. If it exceeds 15 N / 25 mm, it will be difficult to peel off the fixing tape and the base material of the tape surface It may be destroyed or the tape may be peeled off the skin.

As the release liner, a release liner which has been conventionally used to cover the surface of the adhesive layer during storage can be used.

FIG. 2 shows a front view of a different embodiment of the invention for a nasal tube. The same parts as those in FIG. 1 are designated by the same reference numerals. a is provided with two portions that project and extend on the same side of the tube fixing portion, that is, on the left side in the illustrated example, and both portions 21,
A slight space 23 is provided between the lines 22. b is provided with portions 24 and 25 that project from the tube fixing portion on different sides, that is, on the right and left sides, respectively.

In the same manner as in the above, the left and right protruding portions 27, 2 respectively
8 is similar to the above-described embodiment in that the lowermost portion 28 extends largely to the right, but that portion 28 also projects slightly to the opposite side, that is, the left side. Is different. Further, the projecting portion is not formed in a quadrangular shape, but is formed so that the corners are rounded. By thus slightly extending the opposite side, the operation of winding the tube fixing portion of the base material around the tube becomes easier. It is also applicable to the a and b embodiments that the opposite side is slightly projected or the corner is rounded.

In the above-mentioned embodiment, the nose fixing portion is not limited to the shape shown in the figure, but various shapes can be used. For example, the nose fixing portion 5 of FIG.
The shape may be similar to that of the lower protruding portion 28. That is, as shown in FIG. 2d, the nose fixing portion 29 has the same shape as the lower protruding portion 28 of the tube fixing portion 6, and is formed to be vertically symmetrical with respect to the upper protruding portion 27 of the tube fixing portion 6. There is. In particular, by forming in this way, the nose fixing portion 29 can also be used as a tube fixing portion, and therefore, a direction which is easy to operate for right-handed and left-handed persons is selected, and either one of the portions 29 or 28 may be fixed to the nose and the other part 28 or 29 may be wrapped around the tube. Further, with such a shape, it is possible to apply the tube fixing tape so that it can be easily wound regardless of whether the tube is taken out from the left or right nose.

Evenly, and a weak adhesive acrylic adhesive was evenly applied to the area of the tube fixing part under the condition of 100 g / m ² , and the adhesive was coated with silicone-treated release paper into the shape shown in Fig. 4a. Formed.

Example 3: A two-layer laminate sheet having an opening ratio of 15% and a basis weight of 26 g / m ² was prepared by laminating a polyethylene sheet and ethylene vinyl acetate on the surface of a polyester non-woven sheet having a basis weight of 40 g / m ² and ethylene vinyl. A base material is made by laminating the acetate sheet on the polyester non-woven sheet side, and a strong acrylic adhesive is applied to the back surface of the polyester non-woven sheet of the base material.
The composition was uniformly applied by a mesh pattern coating method under the condition of g / m ² , and the adhesive was coated with silicone-treated release paper to form the shape shown in FIG. 4a.

Example 4 Using a urethane foam sheet having a thickness of 2 mm and having an open cell as a base material, one side of the urethane foam sheet was uniformly coated with a strong adhesive acrylic adhesive under the condition of 100 g / m ² , and the adhesion was obtained. A polyethylene sheet with an aperture ratio of 50% and a basis weight of 15 g / m ² was placed on the surface of the layer by pressure bonding, and this polyethylene sheet was coated with silicone-treated release paper.
It was formed in the shape shown in a.

Example 5: A long-chain alkyl-based release agent is applied to the surface of a polyethylene sheet having a thickness of 0.02 mm in a coating thickness of 0.1 to 0.2 μm.
The back side of a sheet that has been treated for approximately m is laminated with a 40 g / m ² basis weight polyester non-woven fabric as the base material, and a pressure sensitive adhesive consisting of polyisobutylene as the pressure sensitive adhesive component and carboxymethyl cellulose as the water absorbing substance is applied with a coating thickness of 0.8 mm. The polyester non-woven fabric was applied uniformly to the back surface of the material and the adhesive was coated with silicone-treated release paper to form the shape shown in FIG. 4a.

Example 6: A low-adhesive acrylic obtained by laminating a polyester non-woven fabric having a basis weight of 40 g / m ² on the back of a polyethylene sheet having a thickness of 0.02 mm as a base material, and mixing silicone oil on the back surface of the base polyester non-woven fabric. A system adhesive was applied at 50 g / m ² and the adhesive was coated with silicone-treated release paper to form the shape shown in FIG.

Comparative Example 1: The same substrate as in Example 1 was used, the same adhesive was used, and the same release paper was used for coating.
The conventional shape shown in FIG. This shape is the nose fixing part 4

The tube fixing portion 48 has portions 411 and 412 protruding from the axis line 410 on both sides.

Comparative Example 2: Using a base material of a polyester nonwoven fabric sheet having a basis weight of 40 g / m ² , the same adhesive as in Example 1 was applied to the back surface of the base material and covered with the same release paper. The product was formed into the conventional shape shown in FIG. 4b.

In the above-mentioned Examples and Comparative Examples, the substrate is the same as in Example 1, Example 2 and Comparative Example 1, the adhesive is the same in Example 1, Comparative Example 1 and Comparative Example 2, and the shape is the same. The example and the comparative example are different from each other. With respect to these examples and comparative examples, as a result of performing a performance test by fixing the nasal tube, the following facts were found. The adhesive surfaces of the tapes of Examples 1 to 6 were easy to handle because the adhesive surfaces were less likely to come into contact with each other during the fixing operation, and Comparative Examples 1 and 2 were particularly caused by their shapes. Then, the adhesive surfaces of the tapes were likely to come into contact with each other and adhere to each other, which was extremely difficult to handle. Regarding the point of peeling the adhesive surface of the tape from the surface of the tape, Examples 1 to 6 and Comparative Example 1 were easy due to the property of the surface of the substrate, but Comparative Example 2 was difficult to peel. Further, particularly in Example 2, by changing the adhesive between the nose fixing part and the tube fixing part and making the adhesive of the tube fixing part weakly adherent, it surely adheres to the nose and to the tube. Is easy to re-adhere and re-peel, and in Example 3, since the base material has air permeability, there is almost no stuffiness or rash due to the base material,
Since the adhesive contained a water-absorbing substance in the adhesive, it absorbed sweat from the skin, and maintained an appropriate humidity, so that the physiological condition of the skin could be well maintained.

[0042]

According to the present invention, since the tube fixing portion of the tape is formed by the portion which projects only one side from the axis of the base material, the adhesive surfaces of the tape adhere to each other during the fixing operation. The tube can be fixed easily and cleanly, and the front surface of the tape and the adhesive layer on the back surface of the tape can be easily peeled and re-adhered even after they are attached to each other. It can be adjusted and re-fixed so that the tube can always be locked in its proper position, thus avoiding pain due to contact between the tube and the patient's body. Further, since the structure is simple and the manufacturing cost is low, it is possible to deal with the case where the disposable type is preferable from the viewpoint of hygiene without fearing the economical efficiency.
