The present invention relates to a first-aid bandage used for promoting healing of the upper part of the spine and for alleviating pain caused by wound healing.

It is common to use a bandage with a liquid-absorbent pad attached to the area corresponding to the upper surface of the window for the purpose of hemostasis, sterilization, and protection of the upper surface of the window when everyday trauma occurs.

However, the liquid-absorbent pad is necessary for the disinfection, the hemostasis and the drainage of the injured surface in the initial stage immediately after the wound in the healing process of the upper part of the window, but in the healing promotion and protection stage, It is necessary to allow the exudate which promotes the healing of the upper part to exist at an appropriate level. Therefore, absorbing and removing the exudate by the absorbent pad is not preferable from the standpoint of protecting the upper part of the window because it delays the healing of the upper part of the window.

In addition, the consumer considers the appearance of the image to the same degree as the original bandage that heals and protects the wound against the minor wound of the self-healing range, and from this point of view, the absorbent pad also has a surface And it becomes a negative factor. Other liquid-absorbent pads make it difficult to stick to the curved surface, and after they are attached, they distort the shape and make it easier to fall off. When the outside liquid is absorbed through the vent holes, the liquid retention is strong and the bacteria grows. (It is preferable in the hemostasis step immediately after wounding, but is not preferable in the healing promotion and protection step after hemostasis) and is usually excellent in warmth. Therefore, when the temperature in summer is high The temperature of the upper surface of the window is further raised to actively propagate the bacteria. As a result, there is a problem that the infection on the upper part of the window is caused and the healing is remarkably delayed.

Therefore, it is desirable to remove the liquid-absorbent pad as soon as possible after a necessary period of time.

Thus, even if the so-called wet method in which the upper surface of the window is kept in the wet environment or the so-called dry method in which the upper surface of the window is guided to the drying environment is selected during the promotion and protection of the upper part of the window, It is possible to prevent the exudate containing the wound healing component indispensable for the promotion of healing from being lost.

However, most of the commercially available bandages have a liquid-absorbent pad such as a rayon non-woven fabric on the contact surface of the wound on the premise that they are used at the initial stage of the healing process of the upper part of the wound immediately after the wound, If it is brought into contact with the upper surface, the drainage is continuously removed even in the healing promotion and protection stages on the upper surface of the window, and the effluent containing the necessary wound healing ingredients is also removed or various other undesirable conditions as described above.

As a known technique relating to a first-aid bandage, a proposal concerning a bandage suitable for use at an early stage such as hemostasis is disclosed in Japanese Patent Application No. 42-10467 (Patent Document 1), Japanese Patent Application Laid-Open No. 5298984 (Patent Document 2) 4-212352 (Patent Document 3), and proposals for a bandage suitable for use in the healing promotion and protection stage are disclosed in Japanese Patent Laid-Open Nos. 58-43428 (Patent Document 4), 58-43429 (Patent Document 5 JP-A-5-68691 (Patent Document 6), and re-publication WO98 / 36719 (Patent Document 7).

Proposals for hemostasis and the like at the early stage of electricity (Patent Documents 1, 2, and 3) are such that the wound contact layer and the absorbent layer are peeled off. Therefore, although these documents are different from the original intended use, when the absorbent layer is temporarily removed and only the wound contact surface is used in the step of promoting and protecting the healing, the function as the original wound contact layer, that is, It is necessary to protect it with a new covering member because the function as a wound coating layer, that is, the covering property and the protection and retention property are lacking.

In addition, when a covering member is required separately from a bandage, it becomes difficult to handle in a home, besides it becomes a serious problem in handling and economical efficiency. Since it is also a problem in appearance, simplicity and portability, It is not practical.

In the initial stage immediately after the wound, the absorbent member described in Patent Documents 4, 5, 6, 7 is used as the absorbent member described in Patent Documents 1, 2 and 3, As a method of using a new covering member in the state where the absorbing member which is the absorbing member described in the documents 1, 2 and 3 is removed, the urgency, applicability, simplicity, portability, economical efficiency, functionality and appearance are remarkably deteriorated As a result, it has not yet been practically used.

In addition, as described above, the band-aid disclosed in Patent Documents 1 to 7 is not sold in the general market and thus can not be obtained by the general public. Therefore, the band-aid is commercially available even in the healing promotion and protection stage.

That is, in the conventional band-aid, a band-aid which can cope with the entire process from the initial stage to the healing promotion and protection stage in the healing process of the upper part of the window has not been developed so far.

It is an object of the present invention to provide a first-aid bandage which can cope with everything from the initial stage of the healing process to the healing promotion and the protection stage in the upper part of the window.

As a result of repeating extensive studies to attain the above object, the present inventors have found that a film surface or a sheet-like base material to be worn by a human body point, a window surface contact portion provided on at least a part of the base material, And a liquid-absorbent pad which is detachably and detachably attached to the wearer's body.

That is, the inventors of the present invention have found that, when at least a part of a base material is provided with a wound surface contact portion, the wound surface contact portion is covered, the absorbent pad is detachably attached to the surface of the wound surface contact portion, When used, the liquid-absorbent pad is brought into contact with the upper surface of the window by using the liquid-absorbent pad in the initial stage immediately after the wound, thereby realizing hemostasis and smoothly absorbing blood and draining from the window, , And in the step of promoting healing and protection of the upper part of the window, it is used in a state in which the liquid-absorbent pad which has been attached and detached is removed, so that the surface of the window is directly brought into contact with the upper surface of the window, As a result, it is possible to promote the healing of the upper part of the window, to improve the appearance of the user's image at the time of use The problem of conventional bandages such as prevention of peeling due to physical distortion, prevention of falling off when contacting with water such as bathing, improvement of blood circulation, prevention of infection at the upper part of the window, etc. I realized that I could.

Hereinafter, the first-aid bandage of the present invention will be described in detail.

A first-aid bandage according to the present invention comprises a "base material" in the form of a film or sheet on a human body point, a "window surface contact portion" provided on at least a part of the base material, Absorbent pad "

The "base" in the first-aid bandage of the present invention is not particularly limited as long as it is flexible and does not impair the feeling of use as a bandage. It is possible to select a film or sheet made of conventional natural fiber and / or man- Can be used. In addition, a laminate of two or more laminated films or sheets may be used.

The film or sheet made of the electric natural fiber and / or the synthetic fiber is generally in the form of paper, cloth, towel, blankets, knitted fabric, nonwoven fabric or woven fabric.

Natural fibers include, for example, cotton, cowpea, flax, linen, hemp, jute, palm, manila hemp, sisal, and plant fibers such as koa fiber, silk wool, wool, cashmere wool, camel wool, , Rabbit hair, and the like.

The man-made fibers include, for example, reclaimed fibers such as artificial warp, viscose and Ben Belk, or recycled fibers such as polyamide fibers, polyester fibers, polyacrylic fibers, polyvinyl alcohol fibers, polyalkylene paraoxybenzoate fibers, Synthetic fibers such as urethane-based fibers, polyvinylidene chloride fibers, polyvinyl chloride fibers, polyacrylonitrile fibers, polyethylene fibers, polypropylene fibers and polychars, semisynthetic fibers such as acetic acid artificial fibers, .

Examples of the film or sheet molded from a polymer material include a film made of a polymer such as polyethylene, polypropylene, polyamide, polyester, polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, polybutadiene, cellophane, polychloroprene, It is possible to use a film or a sheet formed by thinly forming synthetic resin such as nitrile rubber, butyl rubber or silicone rubber, synthetic rubber or the like, and preferably a foamed article of air permeability (moisture permeable) or non-permeable . The non-breathable (non-breathable) film, sheet or foam may be subjected to perforation treatment or stretching treatment to impart breathability (moisture permeability) if desired.

In addition, the first-aid bandage of the present invention is used in a manner of sticking to or wound on a wound, and the shape and size are not particularly limited, but the position of the wound, for example, The shape and size of the substrate to be the main body may be appropriately determined.

Since the first-aid bandage of the present invention is used by sticking to a human body, an adhesive layer is formed over at least a part or all of one side of the electric base.

The adhesive layer formed on at least a part or entire surface of one side of the base material is not particularly limited as long as it has an adhesive force not to be naturally peeled off during use and does not lose adhesion even when brought into contact with moisture such as sweat Generally, a pressure-sensitive adhesive layer formed of a lipophilic pressure-sensitive adhesive can be mentioned.

Specific examples of the lipophilic pressure-sensitive adhesive include a pressure-sensitive adhesive such as a vinyl acetate type pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, a polyvinyl alcohol pressure-sensitive adhesive, a polyvinyl acetal pressure-sensitive adhesive, a vinyl chloride pressure-sensitive adhesive, a polyamide pressure-sensitive adhesive, a polyethylene pressure- A rubber pressure-sensitive adhesive such as a thermoplastic pressure-sensitive adhesive, a nitrile rubber pressure-sensitive adhesive, a butyl rubber pressure-sensitive adhesive or a chloroprene pressure-sensitive adhesive may be used, and its thickness is not particularly limited, but is suitably about 10-70 μm.

The first-aid bandage of the present invention is most notable in that a "sorption pad" which covers the surface of the sorter-contacting portion is detachably attached to the sorter-side contact portion at least on a part of the substrate.

That is, the first-aid bandage of the present invention uses a liquid-absorbent pad with a wound at an early stage of the healing process of the upper part of the window immediately after a wound, thereby bringing the liquid-absorbent pad into contact with the upper surface of the window, In addition, it is possible to protect the wound portion at the same time as absorbing and promoting the healing of the upper part of the window. In particular, in the protection step, the liquid-absorbent pad is directly used on the upper surface of the window, As a result, it is possible to promote the healing of the upper part of the window, to improve the appearance of the user during use, to prevent peeling due to physical distortion, to prevent contact with water such as bathing , The blood circulation is improved, and the upper part of the bandage has a variety of problems It can be solved at any moment.

That is, the first-aid bandage according to the present invention can be used as a single product form throughout the entire period from the initial stage of the healing process to the promotion of healing and the protection of the upper surface of the window by the above-described constitution.

When the first-aid bandage of the present invention is adhered to the upper part of the window, the first part of the emergency bandage of the present invention covers the upper part of the wound and retains the exudate containing the wound-healing ingredient between the upper part of the wound and the contact part of the wound, Permeability, and the like, which have appropriate moisture permeability, air permeability, etc. for each of the dry method and the wet method.

This may be configured such that when the wound surface contact portion is a part of the base material, it is made to be a non-adhesive layer and the effusion fluid having the wound healing component alone is retained by the base layer alone to prevent the blood from being lost. In the case of the sheet, the laminate of the base layer, the adhesive layer, and the film or sheet may retain the exudate containing the wound healing component to prevent the exudation of the exudate.

More specifically, it is preferable to control the window contacting portion by the moisture permeability. In the case of the wet method, the moisture permeability of the window contacting portion is preferably 300 g / m 2 24 h or less, more preferably 100 g / m 2 24 h or less . When the exudate containing the wound healing ingredient is allowed to stay and the loss of the effusion can be prevented, the upper surface of the window can be kept in a humid environment, so that there is no scar on the upper surface of the window, In addition to being able to be smoothly carried out, this liquid-absorbent pad can be easily peeled off without scarring.

On the other hand, in the case of the dry method, the moisture permeability is preferably in the range of 300 g - 8,000 g / m 2 24 h, more preferably 500 - 4,000 g / m 2 24 h. In the dry method, when the moisture permeability exceeds 8,000 g / m 2 24 h, the exudate containing the wound healing ingredient is excessively dried and the effusion required on the top surface of the wound is insufficient or absent.

The moisture permeability measurement method is a precise low moisture permeability measurement method, and the moisture permeability test method of the moisture-proof packaging material of JIS Z0208 is suitable. For the measurement of moisture permeability from low to high humidity, there is a test method of water vapor permeability (apparatus measurement method) of JIS K 7129 plastic film or sheet, or a method of moisture permeability test of JIS L 1099 fiber product. However, JIS K7129 .

That is, in the present invention, the water vapor permeability of 100 g / m 2 24 h or less is measured by JIS Z 0208, and the water vapor permeability of 50-10,000 g / m 2 24 h is measured by JIS K 7129. When the moisture permeability of the window contact part is 100 g / m 2 24 h or less, the method with high precision is selected considering the thickness and flexibility of the test piece.

Therefore, the "first-aid pad" of the present invention is not particularly limited as long as it can retain the exudate containing the wound-healing ingredient between the upper surface of the window and the window-contacting portion, It is preferable that the upper surface of the window is not scratched. Specifically, for example, a non-liquid-pervious film or sheet is used as a base material, and a non-adhesive layer is provided on at least a part of the base material to provide a non-adhesive portion as a window- . This non-adhesive layer means a state in which a substrate is exposed without forming an adhesive layer.

It is also possible to laminate and fix the film or sheet on at least a part of the substrate after the adhesive layer is provided on the substrate to make the film or sheet serve as the window-contacting portion.

Such a film or sheet is not particularly limited, but in the case of the wet method, in addition to the non-breathable film or sheet formed from the above-mentioned polymer material, an adhesive layer is formed on the surface of the breathable film or sheet to adjust the moisture- On the other hand, the dry method is a film or sheet formed of the above-mentioned polymeric material, natural fiber, or man-made fiber and having the moisture permeability adjusted as described above.

In the wet method, a polymer material (including a hydrocolloid) swollen in water is coated on a support (for example, a glass plate or an acrylic plate) having a smooth surface as a window-contacting portion and dried to form a film- When a large amount of exudate is generated in the upper part of the window, the exudate is absorbed and retained in the film, sheet or net, and the exudate The promotion of healing of the upper part of the window can be further improved.

The hydrophilic polymer is not particularly limited as long as it is a polymer material that absorbs water and gels. Specific examples of the hydrophilic polymer include a synthetic water absorbing polymer material such as polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylic acid or its salt, dextran, pectin A natural absorbent polymer material such as polyacrylonitrile, prurane, or gelatin, a semisynthetic absorbent polymer material such as methylcellulose, ethylcellulose, carboxymethylcellulose or a sodium salt thereof, and a mixture of the hydrophilic polymer material and the hydrophobic polymer material. In this case, specific examples of the electrohydrophobic polymer material include natural rubber, synthetic rubber such as styrene block copolymer, polyisobutylene, and the like. The present invention can include one or more species of hydrophilic polymers selected from these hydrophilic polymer materials or mixtures of hydrophilic polymer materials and hydrophobic polymer materials.

As described above, the first-aid bandage of the present invention is preferably formed of a film, a sheet or a net in which the window-contacting portion is non-sticking to the upper surface of the window. The film or sheet may be a film or sheet formed of a water- A film or a sheet formed of a polymer material, a film or a sheet obtained by subjecting the surface of the film to water repellency treatment with silicone resin, fluorine resin, or the like, or a method in which these are subjected to a piercing treatment. May be used.

However, the first-aid bandage of the present invention is most preferably formed from a film or sheet having a non-breathable window surface contact portion or a non-breathable portion corresponding to the window contact portion from the viewpoint of protecting or healing the upper window . In this case also, the film-contacting portion may be formed of a non-breathable film or sheet in the case of a part of the base material, and the film-like sheet or film or sheet may be laminated on at least a part of the base material, The layer of the substrate, the pressure-sensitive adhesive layer, and the laminate of the film or sheet may be formed of a non-breathable film or sheet.

In short, the first-aid bandage according to the present invention is a first-aid bandage of the present invention, in which a sagittal contact portion is provided on at least a part of the base material, and when the sagittal contact portion is covered and the absorbent pad is detachably attached to the surface of the sagittal contact portion, In the initial stage of the healing process in the upper part of the window, by using the liquid-absorbent pad with the liquid-absorbent pad, the liquid-absorbent pad is brought into contact with the upper surface of the window to realize hemostasis immediately after wounding, Can be smoothly absorbed and the wound can be protected. On the other hand, the wound surface of the healing promotion and protection step is used in a state in which the attached liquid-absorbent pad is removed so as to prevent the drying of the upper surface of the window by contacting the upper surface of the window with the upper surface of the window, . As such, the upper surface of the window can be maintained in a humid environment, so that the wound portion can be quickly and smoothly healed. Furthermore, if the absorbent pad is removed, the first-aid bandage can be easily detached without damaging the skin, which is preferable. If the wound surface contact portion is formed of a liquid-permeable film or sheet or a laminated body, the effusion liquid containing the wound healing component is likely to be evaporated and dried, and wastewater such as soapy water or the like may enter the window, And it is possible that the growth of the upper part of the window can not be promoted or protected.

Therefore, in the first-aid bandage of the present invention, the liquid-absorbent pad is detachably attached to the surface of the bed-side contact portion.

The absorbent pad is not particularly limited as long as it is formed of a water absorbent sheet and absorbs blood or draining liquid. Specifically, for example, paper such as tissue paper or towel paper such as household paper or absorbent paper, absorbent foam film or sheet A woven fabric, a woven fabric or a knitted or absorbent polymer material containing a woven fabric, a woven fabric, a knitted fabric or a gauze, or an absorbent fiber such as rayon or cotton, or a nonwoven fabric made of an absorbent polymer such as cotton or rayon, Impregnating, containing, incorporating, transferring or supporting a water-absorbing polymeric material of a nonwoven fabric, woven fabric, knitted fabric or gauze having impregnation, inclusion, incorporation, transfer, And they may be used as a single layer or may be laminated in plural layers Use of a laminate.

The first-aid bandage of the present invention refers to a state in which the absorbent pad is detachably attached to the surface of the electric window contacting portion. However, in the present invention, the first and second adhesive layers refer to a state in which the absorbing pad is lightly attached to the surface of the window contacting portion. Refers to an attachment state to such an extent that the liquid-absorbent pad can be easily peeled off if the liquid-absorbent pad is consciously detached from the surface-contacting portion.

In the present invention, the method of attaching and detaching the liquid-absorbent pad to the surface of the window-contacting portion is not particularly limited. Specifically, for example, a method of sticking the window-contacting portion and the liquid-absorbent pad with a pressure- (B) the adhesive force is lowered by spraying a powder such as polyethylene or polypropylene on the surface of the pressure-sensitive adhesive layer between the window-contacting portion and the liquid-absorbent pad, (c) The pad is made slightly larger and the surface of the liquid-absorbent pad on the side of the surface-contacting portion is subjected to a releasing treatment or the like by silicone resin processing or the like to adhere the edge of the liquid-absorbent pad to the pressure-sensitive adhesive layer provided on the substrate, Is a film or a sheet adhered to an adhesive layer, the surface of the film or sheet is subjected to a releasing treatment or the like Or by attaching the liquid contact pad and the liquid-absorbent pad by an electrostatic attraction, or (f) by controlling the small adhesive area by partially placing the adhesive layer, thereby lowering the adhesive force, etc. .

However, depending on the material of the liquid-absorbent pad, when the liquid-absorbent pad is removed from the window-contacting portion, some of the liquid-absorbent pad or the pressure-sensitive adhesive may remain on the window-contacting portion. In order to prevent this, a non-porous film, a perforated film, net or the like of synthetic resin such as polyethylene or polyester is adhered or fused as a retention film or sheet to the side of the sorption pad of the liquid-absorbent pad, When a resin such as polyethylene is used to apply a coating or spraying method to increase the bonding force between the fibers to the liquid-absorbent pad and to peel off the liquid-absorbent pad or the pressure-sensitive adhesive, the part of the liquid- .

Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings, but the scope of the present invention is not limited thereto.

* About the use test effect

What is required for a general bandage used for magnetic therapy is appearance, simplicity, applicability, portability, economical efficiency, urgency, and functionality in addition to the promotion of healing and protection of the upper part of the window. Among the members constituting the bandage, the absorbent pad plays a large role, and the main action is to absorb and remove hemostasis and drainage. However, the period of time required for such a liquid-absorbent pad is basically not necessary after this time, usually within 24 hours immediately after the wound (time for achieving hemostasis and drainage absorption), and is rather disadvantageous due to the presence of the liquid-absorbent pad.

Specifically, for example, 1) Absorbent pad absorbs and removes exudate containing wound healing component, which plays an important role in the healing process. 2) 3) it is difficult to stick to the curved surface due to the presence of the liquid-absorbent pad and is liable to be physically distorted and fall off; 4) peeling of the peripheral adhesive portion of the bandage, When the liquid absorbing liquid is absorbed through the liquid absorbing pad, the liquid holding ability of the liquid absorbing pad is high, and not only the discomfort, but also the wounds which are healed by blowing the wound portion are worsened rather than bad, Poor blood circulation due to the pressure of the liquid pad is necessary for the early stage hemostatic action in the upper part of the window just after wounding, In the healing process of the healing process, the pressure on the upper part of the window due to the liquid absorbing pad is bad condition from the viewpoint of wound healing. 6) Since the liquid absorbing pad is generally excellent in warmth, And further increase the bacterial divergence. As a result, infections of the upper part of the spleen are caused and the healing is remarkably delayed.

Therefore, it is extremely important to detachably attach the liquid-absorbent pad as in the present invention, and this fact can be evaluated and confirmed in a healing test and an evaluation test on the upper part of the window.

&Lt; Example 5 >

The healing test on the window was performed using the first-aid bandages manufactured in Examples 1 and 2.

The first-aid bandages prepared in Examples 1 and 2 were subjected to sterilization treatment with ethylene oxide gas, and each of the test samples was tested for use by animals.

In the test, the skin of rabbits and the like was cut and disinfected with alcohol, and then the skin was cut into a circular shape having a diameter of 10 mm by selecting 4 places. Then, two samples of each sample were used in the upper part of the skin peeling window, , So that the liquid-absorbent pad was positioned and fixed. In this case, the first-aid bandages prepared in Example 2 were fixed on the upper part of the skin peeling window, and then the carrier film was removed. After one day they were replaced with fresh samples. At this time, one of the two specimens in each example was fixed by affixing the exposed surface-contacting portion and the liquid-absorbent pad to the upper portion of each skin peeling window by removing the liquid-absorbent pad. Three days after the start of the test, the new specimen was exchanged with the same procedure, and the healing progress of the upper part of the window was visually observed.

After the specimen was exchanged, the specimen was again left for 3 days (after 6 days from the start of the test), the specimen was removed, and the healing state on the spear was visually observed. The healing status after 3 and 6 days is shown in Table 1.

division After 3 days (exchange, observation) After 6 days (removal, observation) Review Example 1 (Pad removal after 1 day) Tick formation bleeding, no fixation edema, loss of erythema Tick formation bleeding, no fixation edema, loss of erythema Good course Example 2 (Pad removal after 1 day) Almost healing, no scar bleeding, no adherence, no erythema Healing, no scar bleeding, no adherence, no erythema Good course Example 1 (Always use pads) Partial plaque formation Slightly bleeding, slightly sessile edema, erythema No plaque formation bleeding, slight adherent edema, slight redness Heavy lack of healing Example 2 (always using pads) Partial plaque formation Slightly bleeding, slightly sessile edema, erythema No plaque formation bleeding, slight adherent edema, slight redness Heavy lack of healing

From the results shown in Table 1, it can be seen that, in all of Examples 1 and 2, one day after the removal of the liquid-absorbent pad, the healing of the upper part of the window was clearly promoted and the disappearance of edema and erythema was faster than that without the liquid- I could confirm. The reason for this is interpreted to be that the elimination of the effusion containing the wound healing component by removing the absorbent pad after one day is prevented.

&Lt; Example 6 >

1) Tester: A person who has normal skin without any abnormality such as defects, deformation, abrasion due to drying of skin, work, etc. including skin diseases, both hands and fingers, 10 (5 males, 5 females) were tested in the environment (within the scope of office workers).

2) Specimen: The sample prepared in Electrical Example 1-4 was used.

The first-aid bandages attached with the absorbent pad prepared in Example 1-4 were set as Example 1, Example 2, Example 3 and Example 4, and the absorbent pad prepared in Example 1-4 was used as the absorbent pad The results are shown in Table 1 as Example 1-0, Example 2-0, Example 3-0, and Example 4-0, respectively.

3) Test method: At 10:00 am, attach the first-aid bandage manufactured in step 1 to the second, third, and fourth joints of the right hand and the corresponding parts of the wrist joints so that the absorbing pad is centered, And the first-aid bandages prepared in Example 3 were wound around the fingertips so that the absorbent pad was at the center, corresponding to the joints of the second stunted bone and the dislocated bone. In the same manner, Examples 1-0 and 3-0 were stuck on the left hand with the window contact portion at the center.

Then, at 3:00 pm that day, I washed my hands lightly with a towel 5 times for about 15 seconds every hour until it was removed. After the final rinsing, the specimen was immediately removed to observe the absorbent pad, the skin contact area, and the skin condition where it was stuck, and evaluated according to the following evaluation items. Details of the cleaning method, and the contents of the work during the test period, each of the testers was allowed to act in approximately the same pattern for 4 days.

On the second day, the place to attach the electric specimen was reversed. Examples 1-0 and 3-0 are added to the reverse of the right hand, and Examples 1 and 3 are attached to the left hand in the same manner. So, I was evaluated in the same way as the 3 o'clock PM removal day. The reason for this evaluation test is to eliminate the error caused by the difference between the right hand and the left hand.

On the third day, at 10:00 am, the second, third, and fourth nodes of the right hand are placed at the corners corresponding to the wrist joints, and the second is placed at the center of the absorbent pad. Example 4 was wound around the finger with the liquid-absorbent pad at the center so as to correspond to the joint of the abduction bone. In this case, Example 2 was pasted, and then the carrier film was removed. In the same manner, Examples 2-0 and 4-0 were stuck on the left hand with the window contact portion at the center. Thus, evaluation tests were carried out in the same manner as in the previous method until the removal at 3:00 pm that day.

On the fourth day, the place where the electric specimen was attached was reversed. Examples 2-0 and 4-0 are attached to the right hand of the right hand opposite to that of the hand, and the hands of Example 2 and Example 4 are attached to the left hand in the same manner as in the former. Thus, it was evaluated in the same way as the 3 o'clock PM removal day.

4) Evaluation: The scores of () and () are the sum of the evaluation scores of the left and right fingers for the same specimen, and the total of 10 (5 males and 5 females) were evaluated again.

5) Judgment: A. The effect of the liquid-absorbent pad on the body image was extremely large and could not be improved even in the skin color. This confirms that the same tendency is also attached to the finger.

B. It is confirmed that the liquid-absorbent pad has an extreme effect on the uncomfortable feeling when the liquid is attached.

C. In the case of peeling, it was found that there was almost no difference due to attachment and detachment when attached to a portion other than the finger, and at the same time, the influence of the liquid-absorbent pad on the finger was clearly confirmed.

D. The effect of liquid penetration tended to be more affected by the nonwoven fabric type, but the effect of the liquid absorbent pad was extremely large.

From the above results, it was found that the period of time required for the liquid-absorbent pad is basically an initial stage immediately after the wound, and is basically not necessary after hemostatic and drainage absorption, and is rather disadvantageous due to the presence of the liquid-absorbent pad.

The first-aid bandage of the present invention can be used in the entire process from the initial stage of the healing process of the upper part of the window to the promotion of healing and the protection of the upper side of the window.

That is, since the first-aid bandage of the present invention is constituted such that a soresurface pad is attached to and detached from the surface of the soresurface-contacting portion at the same time as the soresurface portion is provided on at least a part of the substrate, For the wounds on the wounds, use the wipes with a liquid-absorbent pad so that the liquid-absorbent pad is brought into contact with the upper surface of the wipes to achieve hemostasis immediately after wounding, and to smoothly absorb blood or drainage from the upper part of the wing, In the meantime, in the healing promotion and protection step, the liquid-absorbent pad, which is detachably attached and detached, is used in a detached state to contact the wound-contact portion on the upper surface of the window to prevent the loss of the effusion containing the wound- It promotes healing, improves appearance when used, and prevents peeling at the time of bathing, etc. He said, first aid bandage, remove the absorbent pad in addition to improving blood circulation and prevent additional wound infections can be easily removed without damaging the upper surface of the window when removing.

In the case of the first-aid bandage according to the present invention, when the window-side contact portion is the non-adhesive layer portion, since the first-aid bandage is applied to the upper portion of the window in a state in which the non-adhesive layer portion is in contact with the upper surface of the window, When the first-aid bandage is removed, the top surface of the window can be removed very safely without causing any damage.
