Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waterproof wound protector for protecting a wound formed on the skin surface from water wetting and the like.

[0002]

[Prior art]

 Conventionally, first-aid bandages for hygienically protecting wounds on the skin surface have been well known, but in this kind of first-aid bandages, there are few things that even consider protecting the wound area from getting wet. Therefore, when cooking or taking a bath, even if the wound area is protected by the first aid bandage, the protective pad applied to the wound area may get wet and various bacteria may easily grow, or There was a problem that water was soaked in it and it felt pain, and it was necessary to change to a new first-aid bandage every time when cooking or bathing.

Therefore, a waterproof wound protection material as shown in FIGS. 9 to 11 has already been proposed as Japanese Patent Application No. 3-75281 (Japanese Utility Model Application Laid-Open No. 5-24021).

In the figure, a shows an adhesive tape which is formed of a stretchable waterproof film and has one surface as an adhesive surface b and the other surface as a non-adhesive surface c, and a wound protection is provided at the center of the adhesive surface b of the adhesive tape a. The pad d is attached.

The entire adhesive surface b of the adhesive tape a is covered with the release sheet e together with the wound protection pad d. The release sheet e has a boundary portion near the middle portion in the longitudinal direction of the adhesive tape a. Is divided into a pair of release sheet pieces f and g.

Further, a reinforcing sheet h is removably attached to the non-adhesive surface c of the adhesive tape a, and one end of the reinforcing sheet h is not adhered to the adhesive tape a. A start portion i is formed.

Therefore, when using such a waterproof wound protection material, as shown in FIG. 10, the portions of the release sheet pieces f and g corresponding to the wound protection pad d are removed as shown by phantom lines. Then, the wound protection pad d is exposed, and while the wound protection pad d is applied to the wound portion j (see FIG. 11), the release sheet pieces f and g are peeled off in the directions of the arrows, and the adhesive tape a As shown in FIG. 11, the adhesive surface b is closely attached to the skin surface k and attached.

At this time, since the adhesive tape a is in a state of being carried by the reinforcing sheet h, the adhesive tape a can be exactly attached to the skin surface k without causing wrinkles and the like. Finally, the peeling start portion i is picked up and the reinforcing sheet h is peeled off from the adhesive tape a in the direction of the arrow as shown by the phantom line, leaving only the adhesive tape a on the skin surface k.

[0009]

[Problems to be solved by the device]

 However, in the case of the conventional waterproof wound protection material as described above, according to the description in the application specification, the peeling sheet pieces f and g are simultaneously peeled off while the adhesive surface b of the adhesive tape a is placed on the skin surface k. Although it has been described that the adhesive is applied, it is difficult to apply the adhesive surface b 1 of the adhesive tape a to the skin surface k so that the wound protection pad d is firmly adhered to the wound j by such an adhesive method. There is a risk that the pad d may be loosely attached so that it may be lifted from the wound j.

Further, when one hand is injured, the adhesive tape a must be attached with one hand, so that the peeling sheet pieces f and g are peeled off at the same time and the adhesive tape a is removed. It is substantially impossible to attach the adhesive surface b to the skin surface k.

Therefore, as a practical usage pattern that is actually used, one release sheet piece f is peeled off to expose one side of the adhesive surface b of the adhesive tape a and one side of the exposed adhesive surface b. Is attached first while determining the position of the wound protection pad d with respect to the wound j, and then the other side of the adhesive surface b is attached while peeling off the other release sheet piece g. It is thought that there are many.

However, in the case of the conventional waterproof wound protection material, the boundary part m between the pair of divided release sheet pieces f and g is the middle part in the longitudinal direction of the adhesive tape a, and this kind of boundary is used. Since the part m is generally constituted by superposing the end of one release sheet piece f on the end of the other release sheet piece g, the release sheet piece f laminated on the outside is peeled off first. In this case, the end of the remaining release sheet piece g covers most of the wound protection pad d, and if the release sheet piece f is peeled off, the wound protection pad d will be attached to the wound j. Cannot be applied directly to the skin, and after sticking one side of the adhesive surface b of the adhesive tape a to the skin surface k, the remaining part of the adhesive tape b should not touch the wound j that is sensitive to irritation. It was difficult to peel off the release sheet piece g.

In addition, when one piece of the release sheet piece f is peeled off and one side of the adhesive surface b of the adhesive tape a is attached to the skin surface k, if the wound portion j is a place other than the hand (for example, the foot), It is possible to surely stick with both hands, but even if one hand can pick the release sheet piece g left on the adhesive tape a, the other hand will pick the exposed adhesive surface b. However, there was a problem in that the adhesive strength was lowered due to the stains on the hands and oils adhering to the adhesive surface b.

Further, when the reinforcing sheet h is peeled off from the adhesive tape a attached to the skin surface k, the reinforcing sheet h covering the entire non-adhesive surface c of the adhesive tape a with one sheet, Since the peeling start portion i formed at one end of the reinforcing sheet h is picked up and peeled from the end, a physical peeling force is applied to the adhesive tape a already attached to the skin surface k. In this case, the pressure-sensitive adhesive tape a acts from the one end side toward the other end side, and there is a fear that the one end of the adhesive tape a may be separated following the reinforcing sheet h.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a waterproof wound protector capable of solving all the problems of the conventional waterproof wound protectors.

[0016]

[Means for Solving the Problems]

 The present invention provides an adhesive tape formed of a stretchable waterproof film and having one surface as an adhesive surface and the other surface as a non-adhesive surface, a wound protection pad attached to the center of the adhesive surface of the adhesive tape, A waterproof wound protection material comprising a release sheet covering the entire adhesive surface of the tape together with the wound protection pad, and a reinforcing sheet having a predetermined shape-retaining property which is releasably attached to the non-adhesive surface of the adhesive tape. The release sheet is divided into a pair of release sheet pieces with the vicinity of one end in the longitudinal direction of the adhesive tape as a boundary portion, and the reinforcing sheet has a pair of release sheet with the vicinity of the intermediate portion in the longitudinal direction of the adhesive tape as a boundary portion. It is characterized in that it is divided into reinforcing sheet pieces.

Further, a gripping portion protruding outward from the other end of the adhesive tape may be formed at the end of the reinforcing sheet piece attached to the other end in the longitudinal direction of the adhesive tape on the side opposite to the boundary. It is possible.

[0018]

[Action]

 Therefore, according to the present invention, one of the release sheet pieces that is long in the longitudinal direction of the adhesive tape is peeled off first, and one side of the exposed adhesive surface of the adhesive tape is placed on the skin surface while determining the position of the wound protection pad with respect to the wound. paste.

At this time, since the boundary portion of the pair of divided release sheet pieces is near the one end portion in the longitudinal direction of the adhesive tape, the release sheet piece long in the longitudinal direction of the adhesive tape is first peeled off as described above. When the wound protection pad is exposed, the entire surface of the wound protection pad is exposed without being covered by the remaining short release sheet piece, and one side of the adhesive surface is applied to the skin surface while directly applying the wound protection pad to the wound area. Is possible.

Next, the other piece of the release sheet left on the adhesive surface of the adhesive tape is peeled off, and the remaining one side of the adhesive surface exposed by this is attached to the skin surface.

At this time, the adhesive tape attached to the surface of the skin is in a state of being carried by the reinforcing sheet having a predetermined shape-retaining property, so that the adhesive tape fits perfectly on the surface of the skin without wrinkles or the like. Is affixed.

Further, one of the reinforcing sheet pieces is peeled off from the vicinity of the intermediate portion in the longitudinal direction of the adhesive tape toward one end side, and then the other reinforcing sheet piece is removed from the vicinity of the intermediate portion in the longitudinal direction of the adhesive tape to the other end side. Peel it away, leaving only the adhesive tape on the skin surface.

With this configuration, one end of the adhesive tape is prevented from being peeled off following the peeling of the reinforcing sheet.

In addition, a gripping portion that projects outward from the other end of the adhesive tape may be formed at the end of the reinforcing sheet piece attached to the other end of the adhesive tape in the longitudinal direction on the side opposite to the boundary. For example, when the wound is in a place other than the hand (for example, the foot), after peeling off one release sheet piece that is long in the long side direction of the adhesive tape, the peeling left on the adhesive tape with one hand Since the sheet piece can be picked and the gripping portion can be picked by the other hand, it is possible to reliably attach the sheet with both hands without touching the exposed adhesive surface.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

1 to 8 show an embodiment of the present invention, in which 1 is formed of a stretchable resin waterproof film and has one surface as an adhesive surface 2 and the other surface as a non-adhesive surface 3. And a wound protection pad 4 is attached to the center of the adhesive surface 2 of the adhesive tape 1.

The wound protection pad 4 is constructed by covering a sterile gauze of a predetermined thickness with a thin polyethylene net, and the net prevents the wound from adhering to the sterile gauze.

The entire adhesive surface 2 of the adhesive tape 1 is covered with a release sheet 5 together with the wound protection pad 4, and the release sheet 5 has one end in the longitudinal direction of the adhesive tape 1 (in the figure). It is divided into a pair of release sheet pieces 7 and 8 with a boundary 6 near the right side edge).

Here, each of the release sheet pieces 7 and 8 is formed by applying a silicone coating to one surface of the paper piece so that the release sheet pieces 7 and 8 can be easily released from the adhesive surface 2 of the adhesive tape 1.

The boundary portion 6 between the release sheet pieces 7 and 8 is longer than the folded portion 9 formed at the end of the release sheet piece 8 which is short in the longitudinal direction of the adhesive tape 1. The end portion of the release sheet piece 7 which is long in the direction is superposed (see FIGS. 2 and 3).

Further, on the non-adhesive surface 3 of the pressure-sensitive adhesive tape 1, a resin-made reinforcing sheet 10 having a predetermined shape-retaining property is releasably adhered, and the reinforcing sheet 10 has an adhesive tape. It is divided into a pair of reinforcing sheet pieces 12, 13 with a boundary portion 11 near the middle portion in the longitudinal direction of No. 1.

Here, the boundary portion 11 of each of the reinforcing sheet pieces 12 and 13 tightly butts the end portions of each of the reinforcing sheet pieces 12 and 13, and a resin-made covering sheet on each of the butted end portions. 14 is peelably attached, and a peeling start portion 15 that is not in close contact with the reinforcing sheet piece 12 is formed at the end of the covering sheet 14 on the reinforcing sheet piece 12 side.

Further, in the present embodiment, the adhesive tape is attached to the end of the reinforcing sheet piece 12 attached to the other end (the left end in the figure) of the adhesive tape 1 in the longitudinal direction on the side opposite to the boundary. A grip portion 16 is formed so as to extend outward from the other end portion of the grip 1.

Further, as shown in the figure, it is preferable to print an arrow 17 pointing from the reinforcing sheet piece 12 side to the reinforcing sheet piece 13 side on the covering sheet 14, and the peeling start portion of the covering sheet 14 An arrow 18 may be printed in the opposite direction to the arrow 17 on the end of the reinforcing sheet piece 12 covered by the end on the 15th side.

Further, the adhesive tape 1 and the reinforcing sheet pieces 12 and 13 are preferably transparent so that the position of the wound protection pad 4 can be confirmed from the outside.

In the figure, 19 indicates the surface of the skin and 20 indicates the wound.

Therefore, when using such a waterproof wound protection material, as shown in FIG. 4, one release sheet piece 7 long in the longitudinal direction of the adhesive tape 1 and the other release sheet piece 8 are folded. The overlapped end portion of the return portion 9 is picked up and peeled off, thereby exposing one side of the adhesive surface 2 of the adhesive tape 1, and as shown in FIG. The wound protection pad 4 is attached to the skin surface 19 while determining the position thereof.

At this time, since the boundary portion 6 of the pair of separated release sheet pieces 7 and 8 is in the vicinity of one end portion in the longitudinal direction of the adhesive tape 1, as described above, the adhesive tape 1 is peeled long in the longitudinal direction. When the sheet piece 7 is peeled off first, substantially the entire surface of the wound protection pad 4 is exposed without being covered by the remaining short peeling sheet piece 8, and the wound protection pad 4 is directly applied to the wound part 20. It is possible to attach one side of the adhesive surface 2 to the skin surface 19.

Next, the other peeling sheet piece 8 left on the adhesive surface 2 of the adhesive tape 1 is peeled off by pinching the folded back portion 9, and the remaining one side of the adhesive surface 2 exposed by this is attached to the skin surface 19. wear.

However, in the case where the wound 20 is formed in a place other than the hand (for example, a foot), one peeling sheet piece 7 which is long in the longitudinal direction of the adhesive tape 1 is peeled off, and then, as shown in FIG. As described above, the peeling sheet piece 8 left on the adhesive tape 1 is picked by one hand, and the grip portion 16 of the reinforcing sheet piece 12 is picked by the other hand so that the exposed adhesive surface 2 is not touched by both hands. It is also possible to securely paste with.

The adhesive tape 1 attached to the skin surface as described above is in a state of being carried by the reinforcing sheet 10 (reinforcing sheet pieces 12 and 13) having a predetermined shape-retaining property, so that wrinkles or the like are generated. It adheres tightly to the skin surface 19 without causing

Further, as shown in FIG. 7, by grasping the peeling start portion 15 of the covering sheet 14 and peeling it off in the direction of the arrow 17, one of the reinforcing sheet pieces 13 is made to follow the peeling of the covering sheet 14. The adhesive tape 1 is peeled off from the vicinity of the middle portion in the longitudinal direction toward one end side (right side in the figure), and then, as shown in FIG. 8, the other reinforcement that appears by peeling off the covering sheet 14 and the reinforcing sheet piece 13. The end portion of the sheet piece 12 is picked, and the reinforcing sheet piece 12 is peeled from the vicinity of the middle portion in the longitudinal direction of the adhesive tape 1 toward the other end side (left side in the figure), and only the adhesive tape 1 is applied to the skin surface. Try to leave it on 19.

Therefore, according to the above-described embodiment, since the boundary portion 6 of the pair of separated release sheet pieces 7 and 8 is near the one end portion in the longitudinal direction of the adhesive tape 1, the adhesive tape 1 is oriented in the longitudinal direction. By peeling the long release sheet piece 7 first, almost the entire surface of the wound protection pad 4 is exposed and the wound protection pad 4 is directly applied to the wound part 20, while one side of the adhesive surface 2 of the adhesive tape 1 is applied to the skin surface 19. The remaining peeling sheet piece 8 can be easily peeled off without contacting the fingertip with the wound portion 20 which is sensitive to the stimulus.

In addition, when one piece of the release sheet piece 7 is peeled off and one side of the adhesive surface 2 of the adhesive tape 1 is attached to the skin surface 19, if the wound part 20 is in a place other than the hand (for example, the foot), Since the peeling sheet piece 8 left on the adhesive tape 1 can be picked with one hand and the gripping portion 16 can be picked with the other hand, the exposed adhesive surface 2 can be firmly stuck with both hands without being picked. Therefore, it is possible to avoid the problem that the adhesive force is lowered due to the stains on the hands and the oil content on the adhesive surface 2.

Further, since the boundary portion 11 of the pair of divided reinforcing sheet pieces 12 and 13 is located in the vicinity of the middle portion in the longitudinal direction of the adhesive tape 1, the adhesive tape 1 attached to the skin surface 19 to each reinforcing sheet. When the pieces 12 and 13 are peeled off, one of the reinforcing sheet pieces 13 is peeled from the vicinity of the intermediate portion in the longitudinal direction of the adhesive tape 1 toward the one end side, and the other reinforcing sheet piece 12 is attached in the longitudinal direction of the adhesive tape 1. It can be peeled off from the vicinity of the intermediate portion toward the other end side, and the end portion of the adhesive tape 1 can be prevented from being peeled off following the reinforcing sheet 10 (reinforcing sheet pieces 12, 13). .

The waterproof wound protector of the present invention is not limited to the above-mentioned embodiment, but the structure of the boundary portion of each release sheet piece and the boundary portion of each reinforcing sheet piece is shown in the illustrated example. It is needless to say that the present invention is not limited to this, and that various modifications can be made without departing from the scope of the present invention.
