Description

  The present invention relates to an emergency bandage with an ointment in which penetration and leakage of an ointment are effectively suppressed by devising a pad part such as laminating two or more pads and interposing a net.

Various types of emergency bandages are known. A commonly used emergency bandage is a gauze pad that has been impregnated with a chemical solution such as a bactericidal disinfectant or wound treatment agent in the center of the top surface of the adhesive sheet, and the top surface of the pad is left and right. It has a structure coated with a release paper that can be separated.
This type of emergency bandage not only has a risk of damaging the affected area such as the wound mouth because the chemical solution is in a dry state, but also has sufficient sterilization and treatment effects as long as there is no secretion from the wound mouth. Can't get.
An emergency bandage with a medicinal solution-encapsulating capsule body has been proposed for the purpose of improving the above-mentioned problems. A capsule body encapsulating medicinal solution is superposed on the upper surface of a pad, and the upper surface wall of the capsule body is pressed during use. The aluminum foil thin film that forms the bottom surface of the capsule body is destroyed by a sharp protrusion protruding from the center of the bottom surface of the top wall, and the chemical solution in the capsule body flows out and is impregnated onto the pad. Have been developed (see, for example, Patent Documents 1 and 2).

  However, an emergency bandage with a medicinal solution-encapsulating capsule body is not only expensive due to significant man-hours and costs for its production, but also uses a medicinal solution with high fluidity. When destroying the thin film on the lower surface, the chemical solution is likely to scatter and the pad cannot be impregnated accurately, or if the thin film is destroyed with the pad tilted, a part of the chemical solution may flow out to the outside through the upper surface of the pad. In addition, if the capsule is broken with a part of the chemical remaining in the capsule, the effective amount decreases and the therapeutic effect is weakened. Furthermore, since the surface of the pad is directly attached to the wound opening, there is a case where the wound part is damaged when the pad is removed, and the complete cure is delayed.

For this reason, instead of a chemical solution, there is a need to provide an emergency bandage with an ointment applied to the pad, which had previously been thought of but has not yet been practically used. If the pad that is layered is covered with release paper, the ointment may dry in a short time due to the influence of the outside air from the gap between the adhesive sheet and the release paper, or the ingredients may change and the effectiveness may be significantly reduced. Even if it is completely sealed, during carrying or use, if external pressure is applied to the surface of the release paper, the ointment may be crushed and protrude from the pad, making it impossible to use it. When the film is peeled off, the ointment may be transferred to the back surface of the release paper or the like, and the effective amount of the ointment may be reduced.
Further, in order to eliminate such alteration of the ointment and crushing of the ointment due to unexpected external pressure, when the ointment is sealed in the capsule body, the ointment adheres to the wall of the capsule body. It was difficult to transfer a large amount of ointment onto the pad even when the aluminum foil thin film constituting the bottom surface was destroyed by pressing and deforming the capsule body.

  From such a technical background, the present inventor has attached a pad having an ointment layered on the upper surface to the center of the upper surface of the rectangular pressure-sensitive adhesive sheet and faces the center upward on the pressure-sensitive adhesive sheet. The ointment protective cover formed by forming a blister part having a dome-shaped cross-section by bulging and forming into a gentle arc shape is releasably attached, and the pad is attached to the ointment on the pad by the blister part. Proposal was made for an adhesive ointment emergency bandage that was coated with a gap between the lower surface of the blister part (see Patent Document 3).

Japanese Utility Model Publication No. 58-092920 JP-A-63-114626 JP 2001-104367 A

However, the above-mentioned first-aid adhesive bandage with ointment is formed by sticking an ointment protective cover formed with a blister section having a dome-shaped cross section to an adhesive sheet so as to be peelable, and covering the ointment with a gap on the ointment. However, depending on the type and form of the pad, the composition and viscosity of the ointment, the composition of the ointment may change over time. There is a possibility that the ointment and / or the adhesive may be denatured by penetrating to the lower side of the pad and contacting or reacting with the adhesive layer on the upper surface of the adhesive sheet, and effective sterilization and treatment effects cannot be obtained. There was a problem to be solved.
In addition, even though the chemical solution was changed to an ointment, healing simply progressed because the ointment on the pad would directly abut the skin wound with the pad when the ointment was simply layered on the pad. When the wound surface is dry, the wound mouth and the pad may adhere to each other, and there is a concern that the wound will be spread or damaged when it is peeled off after use, and the complete cure is delayed.
Furthermore, if the component of the ointment penetrates below the pad or moves to the outer surface and protrudes, not only makes it difficult to apply the adhesive bandage with ointment to the wound surface easily and reliably, There has been the problem of reducing the effective amount of ointment to be delivered to the wound surface.

  The present invention has been made in view of such problems, and the object of the present invention is to devise the structure of the pad and the net so as to suppress the penetration of the ointment component, so that the layer is deposited on the pad. Can effectively prevent the penetration of the ointment below the pad and the movement to the outer surface, and can effectively prevent adhesion between the pad and the wound, without causing degeneration of the ointment, etc. An object of the present invention is to provide an emergency bandage with an ointment that can effectively apply an ointment to an affected area.

  Under such circumstances, as a result of intensive research to achieve the above object, the present inventor has found that when two or more layers having a high permeability pad as the upper layer and a low permeability pad as the lower layer are laminated, the ointment is absorbed by the capillary phenomenon. Even if it penetrates downward, the formation of the interface between the upper layer pad and the lower layer pad delays the downward penetration of the components of the ointment, causing the ointment to deteriorate or harden. It has been found that this can be prevented over a long period of time.

As a result of further diligent study, the present inventor, as a means of suppressing the permeability of the ointment component, without using a drug component poorly permeable film, conventionally has not been focused on the ointment penetration inhibiting effect, nylon Unexpectedly, the penetration of the ointment component penetration-inhibiting film as well as the ointment component penetration-inhibiting film can be unexpectedly suppressed by interposing the net made of the product between the pads or between the pad and the adhesive tape. Thus, the inventors have found that the air permeability in the pad can be improved since the use of no is used, and the present invention has been completed.

That is, the present invention has been completed based on these findings,

In addition to having advantages, contact with the outside air can be avoided and the use of capsules and the like can be avoided, so that it is possible to effectively prevent deterioration of the ointment and reduction of the effective amount due to transfer.
In the present invention, the ointment protective cover is formed into a blister section having a dome-shaped cross section by bulging and forming the central section upward in a gentle arc shape, or further blister section Are formed in a plane rectangular shape, and both side wall portions on the long side thereof are formed as standing wall portions inclined in a direction approaching each other upward from the lower end, or further, an ointment protective cover is provided. The upper part of the pad part with the ointment on the upper surface is formed on the rectangular adhesive sheet, and the blister part on the plane rectangle in which the four-sided peripheral wall part is formed higher than the thickness of the pad layered with the ointment. Swelled, formed, and releasably attached, and the pad part is covered with the blister part, and further, the blister part has a length on the ceiling wall part. Countercurrent bulging toward the parallel ridges upwardly, by as those formed, in addition to the advantages, can be firmly prevented like accidental crushing when carried.

A specific embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 5, a pressure-sensitive adhesive sheet 2 serving as a base of an emergency bandage 1 is a flexible thin synthetic resin sheet, nonwoven fabric, or woven fabric. An adhesive is layered on the entire upper surface of a rectangular sheet piece having a certain width and a certain length made of paper or the like, and this adhesive layer 3 is formed by applying an adhesive to the upper surface of the sheet piece. Is formed.
Furthermore, the lower surface of the pad part 5 carrying the ointment 4 described in detail later is stuck to the adhesive layer 3 at the center of the upper surface of the adhesive sheet 2.

  Further, an ointment protective cover 8 is superimposed on the pressure-sensitive adhesive sheet 2, and the lower surface of the ointment protective cover 8 is detachably attached to the pressure-sensitive adhesive layer 3. The ointment protective cover 8 is a thin sheet made of a transparent synthetic resin such as vinyl chloride resin which is non-breathable and has an appropriate rigidity, and is a rectangle having the same width as the pressure-sensitive adhesive sheet 2 and a shorter length than the pressure-sensitive adhesive sheet. It is formed in a shape. Further, a constant width and a constant length portion of the central portion of the ointment protective cover 8 in the length direction are bulged upward and formed into a gentle arc shape to form a blister portion 81 whose lower end is fully opened. Forming.

  The release films 91 and 92 are detachably attached to the adhesive layers 3 at both ends of the pressure-sensitive adhesive sheet 2 projecting from both ends of the ointment protective cover 8, and the inner ends of the release films 91 and 92 are attached. The portions extend to the lower surfaces of both ends of the ointment protective cover 8, and the extended portions are folded upward to form overlapping end portions 91a and 92a, and both ends of the ointment protective cover 8 are placed on the overlapping end portions 91a and 92a. The part is placed.

The shape of the pad portion 5 will be described in more detail with reference to FIG. 2. The pad portion 5 is composed of at least two pads, two pads 51 and 52 in FIG. The ointment 4 made, synthetic fibers such as nylon or natural fibers having substantially the same shape as each pad, and a first net 71 interposed between the pads 51 and 52; A net 71 and a second net 72 covering almost the entire side surface of the pad portion are formed, and the lower surface of the pad portion 5 is stuck on the pressure-sensitive adhesive layer 3 of the pressure-sensitive adhesive sheet 2.

The upper layer pad 51 and the lower layer pad 52 that are laminated in two or more layers are made of gauze, absorbent cotton, other woven fabrics, non-woven fabrics, soft plastic fibers, or a laminate thereof, and are rectangular, and the width is the above The pressure-sensitive adhesive sheet 2 is formed smaller than the width and shorter in length.
Each pad 51, 52 uses a different material, and can give strength to the permeation suppression of the components of the ointment 4, but even if fibers of the same material are used, two or more pads are used, By providing an interface between the pads, it has been found that the penetration of the ointment 4 fluid component due to capillary action is suppressed, and rather it is cheaper to use the same material while maintaining high quality. Industrial production is also advantageous.

  Further, in FIG. 2, between the two pads 51 and the pad 52, a net 71 for suppressing the penetration of an ointment made of paper, plastic or the like having the same plane shape as the pads 51 and 52 is interposed. The upper layer pad 51, the net 71 and the lower layer pad 52 are covered with the net 7 on both sides of the lower surface pad 52, and both side surfaces of the net 7 are integrally fixed to both side surfaces of the pad portion 5 by heat welding, A small amount of the ointment 4 is applied to the upper surface of the pad portion 5 through the mesh 7a (not shown) of the net 7 from above the net 7. Accordingly, the ointment 4 is held by the mesh 7a of the net 7, and there is no possibility of flowing on the pad 5 in the plane direction.

  The ointment protective cover 8 having the blister part 81 can be formed in various shapes. However, as described in Japanese Patent Application Laid-Open No. 2001-104367, the ointment protective cover 8 has a planar rectangular shape, and the central part is gently upward. A blister portion 81 having a dome-shaped cross section is formed by bulging and forming a circular arc shape, and both side wall portions on the long side of the blister portion 81 are inclined so as to approach each other upward from the lower end. Forming a wall portion, and a pad portion on which the ointment is mounted on the upper surface is formed on a rectangular adhesive sheet, and the four-sided peripheral wall portion is formed higher than the thickness of the pad portion 5 layered with the ointment; It is preferable that the pad portion 5 be covered with the blister portion 81 by being detachably attached. In the case of the same covering method for the ointment protective cover, the blister part, the standing wall part, and the pad part 5, the description of that aspect is directly referred to in the description of the present invention.

That is, in FIG. 1 and FIG. 2, the shape of a typical ointment protective cover 8 is shown, and the pad portion 5 adhered to the center of the upper surface of the rectangular pressure-sensitive adhesive sheet 2 is covered with a blister portion 81. Then, the lower surface of the ointment protective cover 8 including the lower surface of the outer peripheral portion of the open end of the blister portion 81 in the state of being housed in the blister portion 81 is removed from the lower surface of both ends of the ointment protective cover 8 in the length direction. The adhesive layer 3 is attached so as to be peelable.
The ointment protective cover 8 is made of a transparent synthetic resin thin sheet such as a vinyl chloride resin that is non-breathable and has an appropriate rigidity, and has the same width as the pressure-sensitive adhesive sheet 2 and a shorter length than the pressure-sensitive adhesive sheet 2. It is formed in a rectangular shape. Further, the ointment protective cover 8 has a dome-shaped cross-sectional shape in which a constant width and a constant length portion of the central portion in the length direction bulge upward in a gentle arc shape, and the lower end is fully opened by molding. It is formed in the blister part 81.

The blister part 81 is designed to be slightly larger than the pad part 5 at the four sides of the opening end of the blister part 81 so as to be housed in the opening part 82.
Further, on the long side of the lower end of the opening of the blister part 81, both sides thereof are formed as standing wall parts having a crescent-shaped cross section inclined in a direction approaching each other upward from the long edge side of the opening end.
Moreover, the height of the ceiling wall portion 84 of the blister portion 81 is formed slightly larger than the thickness of the pad portion 5 on which the ointment 4 is layered, and thus is accommodated in the open end of the blister portion 81. There is a gap between the pressure-sensitive adhesive layer 3 on the pad portion 5 and the lower surface of the ceiling wall portion 84 of the blister portion 81, and the pressure-sensitive adhesive layer 3 adheres to the lower surface of the ceiling wall portion 84 of the blister portion 81. It is configured not to.

  The emergency adhesive bandage configured in this way is not only effective in suppressing the penetration of the four components of the ointment into the lower layer pad 52 but also the lower layer pad 52 is more effective than simply laminating two pads. In addition to functioning as an impregnation material when the four components of the ointment permeate from time to time, it also becomes a kind of cushioning material, and when applying an emergency bandage, it presses softly with moderate pressure on the wound, damaging the wound It also has the advantage that it can be treated without any problems.

  Next, in use, first, the ointment protective cover 8 is peeled off from the pressure-sensitive adhesive sheet 2. At this time, both ends of the ointment protective cover 8 are not attached to the adhesive sheet 2, and the release films 91 and 92 are interposed between the both ends and both ends of the adhesive sheet 2. The end of the adhesive sheet 2 is picked with the fingertip of one hand, the end of the ointment protective cover 8 is picked with the fingertip of the other hand, and these ends are separated, so that the ointment protective cover 8 is removed from the adhesive sheet 2 with one touch. The pad portion covered with the blister portion 81 can be exposed. Next, the release films 91 and 92 are removed from both ends of the pressure-sensitive adhesive sheet 2, and then the ointment 5 layered on the pad portion 5 is applied to the wound mouth, and the pressure-sensitive adhesive sheet 2 is applied to the skin surface. To wear.

FIG. 3, FIG. 4 and FIG. 5 show another embodiment of the present invention, and shows an emergency bandage using a pad portion 5 formed in another shape.
In FIG. 3, the pad portion 5 </ b> A has a first net 71 a interposed between two pads 51 and 52, and yet another first net 71 b is interposed between the lower layer pad 52 and the adhesive tape 1. Furthermore, the second net 72 is covered on both sides of the lower surface of the upper layer pad 51, the first net 71a, the lower layer pad 52, and the other first nets, and both side surfaces of the net 72 are disposed. Is fixed to both sides of the pad portion 5 by heat welding, and a predetermined amount of the ointment 4 is applied to the upper surface of the pad portion 5 from the net 72 through the mesh 62a (not shown) of the second net 72. It is thinly layered by doing. Therefore, the ointment 4 is held in the mesh of the second net 72 and there is no possibility of flowing on the pad 5 in the plane direction.
The pad portion 5B shown in FIG. 4 is a first net that is formed by laminating two pads, an upper layer pad 51 and a lower layer pad 52, having a planar shape substantially the same as the pads 51 and 52, and suppressing the penetration of the components of the ointment 4. 71 is configured to be interposed between the lower layer pad 52 and the adhesive sheet 2. The upper layer pad 51, the lower layer pad 52, and the lower surface both sides of the first net 71 are covered with the second net 72, and the both sides of the net 72 are fixed to the both sides of the pad portion 5B by heat welding. The ointment 4 is applied to the upper surface of the pad portion 5B through the mesh 6a (not shown) of the net 72 from the net 72, thereby thinly layering it. Since the other structure of the emergency bandage provided with the pad portion 5B formed in this way is the same as that in the above embodiment, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this pad 5B, the presence of the interface formed between the pad 51 and the pad 52 makes it difficult for the components of the ointment 4 to penetrate into the lower layer pad 52. The first net 71 is sandwiched between the lower layer pad 52 and the adhesive sheet via the net 72 and has a sufficient distance, so that the components of the ointment 4 come into contact with the adhesive 2 of the adhesive sheet 2 and are altered. Never do.

The pad portion 5 </ b> C in FIG. 5 includes an upper layer pad 51, a lower layer pad 52, and two pads, and a first net 71 that suppresses the penetration of the components of the ointment 4 between the upper layer pad 51 and the lower layer pad 52. And a film 6 for suppressing ointment penetration, which may be a perforated film body, made of paper or plastic having the same shape, for example, the same shape, and the lower surface pad 52 and the adhesive sheet 2. Further, the upper layer pad 51, the first net 71, the lower layer pad 52, and the ointment penetration inhibiting film 6 are covered with the net 72 across both sides of the lower surface of the net 72. Both side surfaces of the pad portion 5 are integrally fixed to both side surfaces of the pad portion 5 by heat welding, and the ointment 4 is placed on the upper surface of the pad portion 5 from the net 72 through a mesh 62a (not shown) of the net 72. Coating It is thinly particle course by Rukoto. Since the other structure of the emergency bandage provided with the pad portion 5C formed in this way is the same as that of the above-described embodiment, the same portions are denoted by the same reference numerals and detailed description thereof is omitted.
When the first net 71 is interposed between the upper layer pad 51 and the lower layer pad, the pad portion 5C has a configuration in which the ointment penetration inhibiting film 6 is interposed between the adhesive sheet 2 and the lower layer pad 52. This indicates that the permeability of the components of the ointment 4 can be reliably suppressed, and the cushioning property of the lower layer pad and the avoidance of contact with the adhesive 2 can be sufficiently achieved.
