Description

  The present invention relates to improvement of an emergency bandage in which an ointment is attached to a pad during use and then the pad is attached to the skin surface of an affected area such as a wound to treat the affected area.

  Conventionally, as an emergency bandage to treat the affected area such as wounds more effectively, an ointment is applied to the pad that is attached to the adhesive sheet, and this pad is applied to the affected area. Emergency bandages are known. For example, as described in Patent Document 1, a pad formed by applying an ointment on the upper surface is stuck on the adhesive layer of the adhesive sheet, and the pad has a length shorter than the length of the adhesive sheet; Covering with a protective cover made of synthetic resin that has a recess formed by bulging upward in the center, and with the pad placed in the recess, the lower surface of the outer periphery of the protective cover can be peeled off to the adhesive sheet Further, release paper is attached to both ends in the length direction of the pressure-sensitive adhesive sheet, the inner ends of these release papers are folded upward, and both ends of the protective cover are placed on the folded ends. Superimposed adhesive bandages have been developed.

In use, the end of the pressure-sensitive adhesive sheet to which one release paper is attached is bent downward so that the fingertip can be easily hooked on one end of the protective cover. The protective cover is removed from the pressure-sensitive adhesive sheet by pulling it upward with the fingertips. After that, both the release papers are peeled off, and the pressure-sensitive adhesive sheet is adhered to the skin surface with the pad applied to the affected area. .

  However, in the structure of the emergency bandage as described above, the ointment is pre-applied on the pad. Therefore, even if the emergency bandage is stored in a flat wrapping paper bag, the outside air or the like remains in the adhesive sheet. Through the gap between the protective cover and the release paper into the protective cover covering the pad, which may alter or harden the ointment on the pad and reduce the therapeutic efficacy. There was a possibility that it could not be used. In addition, when it is not necessary to use an ointment or when it is desired to impregnate a pad with another chemical instead of an ointment, it is difficult to remove the ointment from the pad. There was a problem that it could not be used.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to allow easy and easy application on a pad at the time of use without applying an ointment on the pad. In addition, when not in use, the ointment can be prevented from being altered or hardened, and the pad can be left as it is without applying the ointment or it can be impregnated with a desired chemical solution It is to provide an emergency bandage that can be used in the field.

  In order to achieve the above object, an emergency bandage according to claim 1 of the present invention comprises an adhesive sheet having a pad attached to the center portion of the upper surface, and a recess having a size capable of covering the pad at the center portion. The upper portion of the concave portion is formed into an ointment containing chamber which is bulged upward and the central portion of the concave portion is further bulged upward so that the upper wall surface can bend and deform downward. A molded sheet that forms a film outlet that leads from one end of the film to the outside, and the upper outer peripheral part of the upper film part of the molded sheet that is disposed in a folded state in the concave part of the molded sheet is detachably attached to the concave part. A drawing piece that seals the ointment contained in the ointment containing chamber at the center of the upper surface of the ointment and wears the end of the lower film part from the recess to the outside through the inside of the outlet. Band formed in the part The molded sheet is overlaid on the pressure-sensitive adhesive sheet so that the ointment storage chamber is located on the center of the pad, and the outer peripheral portion of the lower surface of the molded sheet is the outer peripheral portion of the pressure-sensitive adhesive sheet. It has a structure that is detachably attached to the upper surface.

  In the emergency bandage configured as described above, the invention according to claim 2 is characterized in that the film outlet extends from one end of the opening end of the recess to one end of the molded sheet in the center in the width direction at one end of the molded sheet. The part is formed by bulging upward, and a notch for drawing is formed at the end of the film outlet, with the upper surface of the end of the band-shaped sealing film exposed to the outside. To do.

  Furthermore, the invention according to claim 3 is characterized in that a release paper is interposed between the lower surface of the strip-shaped sealing film on the outlet side and the upper surface of the adhesive sheet.

  According to the first aspect of the present invention, an adhesive sheet having a pad attached to the center portion of the upper surface is overlaid with a molded sheet having an ointment storage chamber corresponding to the pad in the center portion. Since the lower surface outer peripheral part is detachably attached to the outer peripheral part upper surface of the adhesive sheet, the adhesive sheet and the adhesive sheet can be placed in an accurate position on the pad without using a release paper. It is possible to provide an emergency adhesive bandage that has a structure in which the molded sheet is adhered to the pad so that the ointment storage chamber does not unexpectedly move away or release from the pad.

  Furthermore, the molded sheet has a concave portion having a size capable of covering the pad at the center thereof, and is bulged upward, and an ointment storage chamber is further provided at the central portion of the recess. Since the ointment storage chamber is sealed by the upper film portion of the band-shaped sealing film that is bulged and disposed in a folded state in this recess, a molded sheet or a band-shaped sealing film Is formed from a non-breathable synthetic resin sheet or synthetic resin film to ensure that the ointment is kept sealed in the containment chamber and can be altered or cured over a long period of time. Therefore, at the time of use, this ointment can be applied on the pad and used for the treatment of the affected area without reducing the efficacy.

  Furthermore, since the concave portion is bulged upward in the molded sheet and the pad on the adhesive sheet is accommodated in the concave portion together with the band-shaped sealing film, the molded sheet is stacked on the adhesive sheet. In spite of being stuck together, the pad is in a stable state in a predetermined form in the recess without applying excessive clamping pressure to the pad, the band-shaped sealing film and the ointment storage chamber. Can be stored and held.

  In addition, while pulling one end of the band-shaped sealing film from the outlet provided in one end of the molded sheet, the band-shaped sealing film sealing the lower end opening of the ointment storage chamber is peeled off Since the band-shaped sealing film can be opened gradually, and the band-shaped sealing film is disposed in the recess of the molded sheet, the sliding force between the pad and the band-shaped sealing film is extremely high when the ointment storage chamber is opened. Accordingly, the ointment storage chamber can be smoothly opened by simply pulling the band-shaped sealing film lightly with a slight tensile force.

  After opening, the upper wall surface of the ointment storage chamber is pressed downward, so that the ointment in the storage chamber can be accurately adhered and applied onto the pad, and the molded sheet is then removed from the adhesive sheet. By peeling and removing, it is possible to use it on the affected area. Further, by removing the molded sheet while the ointment storage chamber is sealed with the sealing film without peeling off the band-shaped sealing film, the pad to which the ointment in the ointment storage chamber is not attached or applied is removed. It can be used as it is, and can also be used by sticking a pressure sensitive adhesive sheet to an affected part after impregnating a pad with a desired chemical solution or the like instead of an ointment.

  According to the second aspect of the present invention, the film outlet extends from one end of the open end of the recess to one end of the molded sheet, and bulges upward in the center in the width direction at one end of the molded sheet. Since it is molded, the strip-shaped sealing film can be smoothly pulled out from the outlet by a small tensile force, and the upper surface of the end of the strip-shaped sealing film is exposed to the outside at the end of the film outlet. Since the notch for drawing is formed, when not in use, the drawing piece formed by the end of the band-shaped sealing film is immersed in the drawing port without protruding from the drawing port to the outside. Therefore, it is possible to prevent the band-shaped sealing film from being unexpectedly pulled to open the ointment storage chamber, and to put the fingertip into the notch for withdrawal during use. Push By tensioning the pull-out direction along the outlets in only state, it can be easily opened ointment containing chamber.

  According to the invention of claim 3, since the release paper is interposed between the lower surface of the strip-shaped sealing film on the outlet side and the upper surface of the pressure-sensitive adhesive sheet, the strip-shaped sealing film is pulled out to store the ointment storage chamber. After the pad is impregnated with the chemical solution, the molded sheet can be easily and securely peeled and removed from the part where the release paper is provided, and the end of the adhesive sheet of the adhesive sheet is covered with this release paper. Therefore, it is easy to stick the pad on the affected area after sticking the adhesive surface on the edge side of the adhesive sheet where the release sheet is not provided by picking this part with the fingertip and sticking the skin surface near the affected area And it can be done accurately.

  Next, a specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal side view of an emergency bandage, FIG. 2 is a perspective view, and FIG. 3 is an exploded perspective view. The pressure-sensitive adhesive sheet 1 serving as the base of the adhesive bandage has a pressure-sensitive adhesive layer 2 on the entire upper surface of a thin sheet made of a synthetic resin having flexibility or a rectangular sheet piece having a certain width and a certain length made of nonwoven fabric, woven fabric, paper or the like. A flat rectangular pad 3 made of a sterilized and sterilized non-woven fabric or gauze or the like is adhered to the center of the upper surface of the pressure-sensitive adhesive sheet 1. The pressure-sensitive adhesive sheet 1 is covered with a concave portion 5 provided at the central portion of the molded sheet 4 that is detachably attached to the pressure-sensitive adhesive layer 2.

  The molded sheet 4 has a relatively rigid synthetic resin such as transparent or translucent polypropylene formed in a flat rectangular shape having the same width and the same length as the pressure-sensitive adhesive sheet 1, that is, the same size as the pressure-sensitive adhesive sheet 1. The recess having a planar shape that is slightly larger than the planar shape of the pad 3 and a height (depth) that is substantially equal to the thickness of the pad 3 and that can cover the pad 3. 5 is formed so as to bulge upward, and the central portion of the recess 5 is further bulged upward to form an ointment containing chamber 6 that is slightly smaller in plan than the pad 3. From the one end of the lower end opening of the recess 5 to one end of the molded sheet 4, the height is the same width as the recess 5 and the height (depth) is greater than the thickness of the band-shaped sealing film 8 described later. The outlet 7 that leads to the outside It is formed. That is, the outlet of the strip-shaped sealing film 8 that communicates with the outside from one end of the lower end opening of the recess 5 between the opposing surfaces of the central portion in the width direction at one end in the length direction of the adhesive sheet 1 and the molded sheet 4. 7 is formed.

  Further, the center of one end portion of the molded sheet 4 at the opening end of the outlet 7 is cut into a semicircular shape to form a notch portion 7a for drawing which exposes the upper surface of a later-described drawing piece portion 8c of the band-shaped sealing film 8. is doing. Further, the upper wall surface of the ointment storage chamber 6 in the molded sheet 4 is formed so as to be able to be bent and deformed downward by the pressing force of the fingertip.

  The band-shaped sealing film 8 is made of a thin flexible synthetic resin film that is soft and has high tensile strength, and has a width that is substantially equal to or slightly narrower than the width between the opposing side walls of the recess 5. The length of the sealing film 8 is longer than the length of the recess 5 by a length corresponding to the length of the outlet 7. The band-shaped sealing film 8 is folded in half from the central portion in the length direction so that only a length portion approximately equal to the length protrudes, and the length portion not having the protruding portion is on the upper side and the refracting portion Is placed in the recessed portion 5 in a state of facing the other end of the molded sheet 4 in the length direction, and the outer peripheral portion of the upper surface of the upper film portion 8a is applied to the ointment. The outer periphery of the upper end of the recess 5 that is horizontally refracted in four directions from the lower end opening edge of the storage chamber 6 The lower surface through an adhesive layer 9 peelably adhered to to seal the ointment 10 which is accommodated in the ointment accommodation chamber 6 in upper central portion of the upper film portion 8a.

  Further, the one end portion of the lower film portion 8b superimposed on the lower surface of the upper film portion 8a via the refracting portion, that is, the end portion protruding from the overlapping portion is defined as the extraction piece portion 8c. The inside of the outlet 7 is inserted into the outlet 7 from one end of the lower end of the opening of the recess 5 and the top surface of the recess 5 is exposed to the notch 7a without being protruded from the outlet 7 to the outside. It is arranged so that it can be pulled out from.

  Further, the adhesive layer 2 between one end of the pressure-sensitive adhesive sheet 1 is covered with a release paper 11 that can be peeled off from one end surface of the pad 3 attached to the central portion on the pressure-sensitive adhesive sheet 1, and the belt-like sealing The lower film portion 8 b of the film 8 is inserted into the outlet 7 through the release paper 11 without being attached to the adhesive layer 2 of the adhesive sheet 1. Note that the release paper 11 is formed on the tab 11a by folding the other end facing the one end surface of the pad 3 in an abutted state upward.

  Thus, the ointment storage chamber 6 provided in the molded sheet 4 is sealed by the upper film portion 8a of the band-shaped sealing film 8 disposed in the recessed portion 5 in a folded state. One half is overlaid on the adhesive sheet 1 through the release paper 11 and one half of the strip-shaped sealing film 8b on the release paper 11, and the other half outer peripheral lower surface of the molded sheet 4 is placed on both side end faces of the pad 3. By sticking to the other end part of the adhesive layer 2 exposed outward from the other end surface of the adhesive layer 2 and the pad 3 on both sides of the adhesive sheet 1 exposed outward from The pad 3 is covered with the recess 5, and an emergency adhesive plaster is provided in which the ointment storage chamber 6 is disposed on the center of the pad 3 with a band-shaped sealing film 8 placed thereon.

  The emergency adhesive bandage configured as described above has a molding sheet 4 having an ointment containing chamber 6 sealed with a band-shaped sealing film 8 before use, and the lower surface of the outer peripheral edge of the other half on the other half side. Since it is stuck to the pressure-sensitive adhesive layer 2 of the pressure-sensitive adhesive sheet 1, the ointment storage chamber 6 provided in the molded sheet 4 is not likely to come off from the pressure-sensitive adhesive sheet 1, and is stuck on the pressure-sensitive adhesive sheet 1. The form superimposed on the pad 3 can be held and the pad 3 is received in the recess 5 of the molded sheet 4, so that the outer peripheral portion of the upper surface thereof is covered with the band-shaped sealing film 8. The ointment storage chamber 6 can be positioned on the center portion of the pad 3 while being lightly pressed against the outer peripheral edge of the lower end of the opening of the storage chamber 6. Further, since the molded sheet 4 is made of a synthetic resin sheet having rigidity, it is possible to maintain a predetermined shape that is not easily bent or deformed into a bowl shape.

  Next, in use, the drawing piece 8c of the strip-shaped sealing film 8 exposed to the outside through the notch 7a formed on the upper surface of one end of the opening end of the drawing port 7 of the molded sheet 4 is put together with the drawing port 7 with the fingertip. When the pulling piece 8c is pulled outward while being picked up, the pulling piece 8c is pulled out from the opening end of the outlet 7, so that when the drawn piece 8c is picked and further pulled out, FIG. As shown in FIG. 4, the upper film portion 8a reversely moves downward through the refracting portion as the lower film portion 8b of the strip-shaped sealing film 8 slides on the pad 3 and is drawn to the outlet 7 side. The lower end of the ointment storage chamber 6 is gradually opened from the other end side while peeling from the adhesive layer 9 layered on the lower surface of the upper end outer peripheral wall of the recess 5.

  At this time, the pad 3 and the ointment accommodating chamber 6 are accommodated in the recess 5, the clamping force by the facing surfaces of the pressure-sensitive adhesive sheet 1 and the molded sheet 4 is extremely small, and the drawn piece portion 8 c of the strip-shaped sealing film 8. Since the belt-like sealing film 8 can be easily opened with a small tensile force because the belt-like sealing film 8 is inserted into the outlet 7 having the constant vertical opening width.

  Thus, as shown in FIG. 5, when the strip-shaped sealing film 8 is completely pulled out from the outlet 7, as shown in FIG. 6, the upper wall surface of the ointment storage chamber 6 is pressed downward with a fingertip. The ointment 10 stored in the storage chamber 6 is attached and applied to the center of the upper surface of the pad 3 by being bent and deformed. Thereafter, the molded sheet 4 is peeled off from the pressure-sensitive adhesive sheet 1 from one end side of the molded sheet 4 which is prevented from sticking to the pressure-sensitive adhesive sheet 1 on the pressure-sensitive adhesive layer 2 by the release paper 11 (see FIG. 7), and then the release paper 11 is picked and the ointment application pad 3 is applied to the affected area such as a wound mouth, and the adhesive layer 2 of the adhesive sheet 1 not provided with the release paper 11 is placed around the affected area. The adhesive layer 2 is adhered to the skin surface, and then the adhesive layer 2 is adhered to the skin surface while peeling the release paper 11 from the adhesive layer 2.

  Further, when the ointment is not required, the ointment can be obtained by removing the molded sheet 4 while the ointment storage chamber 6 is sealed with the sealing film 8 without peeling off the belt-like sealing film 8. The pad 3 to which the ointment in the storage chamber 6 is not attached or applied can be used as it is, and it is also possible to use the pad 3 in a state where a desired medicinal solution is impregnated in place of the ointment.

  In the emergency bandage configured as described above, the adhesive layer 9 layered on the lower surface of the upper outer peripheral wall of the concave portion 5 to which the upper film portion 8a of the band-shaped sealing film 8 is adhered is peeled off. As shown in FIG. 3, the pressure-sensitive adhesive layer portion on the start end side is formed in a mountain-shaped pressure-sensitive adhesive layer portion 9a that gradually becomes wider toward the opening start end side of the ointment storage chamber 6. Desirably, if formed in this way, when peeling the upper film portion 8a of the band-shaped sealing film 8 sealing the ointment storage chamber 6, the peeling starts from the center in the width direction, Easy and accurate peeling is possible.
