Description

[0001] The present invention relates to a cooling bandage comprising at least one absorbent core and at least one cooling unit, preferably designed as a cold pack or comprising at least one such unit. The cooling bandage is particularly suitable for use during the postpartum period.

[0002] Such cooling pads are primarily used in gynecological and pediatric departments in hospitals, birthing centers, or also in outpatient or home-based aftercare to alleviate perineal complications after childbirth.

[0003] US patent 2012 / 0089106 A1 discloses an absorbent article comprising a top layer with a contact surface that is in contact with the skin of a wearer and a liquid-impermeable bottom layer and an absorber provided between the top layer and the bottom layer, comprising a material with a cooling effect that contains a refreshing agent.

[0004] Devices for thermal therapy of the perineum and rectal area of ​​a patient have been disclosed in US patent 2018 / 0021168 A1.

[0005] According to a study, perineal injuries occur in 62% of all natural births. Such injuries can include, for example, a perineal tear, an internal injury, or an episiotomy.

[0006] Cooling bandages are often used during the postpartum period to draw potentially infectious discharge from a wound into an absorbent area. At the same time, the cooling effect is intended to further promote wound healing.

[0007] The cooling effect of the cooling unit is particularly helpful in relieving pain, reducing swelling, slowing cell metabolism, and reducing inflammation. Overall, the cooling effect can significantly reduce the need for pain medication.

[0008] Furthermore, such a cooling bandage can also be used as a cooling pad after surgical procedures in the perineal area or more generally, e.g., in the genital area, in both men and women, to absorb secretions, infectious discharge, or wound fluid and to cool the wound. The cooling bandage can also be used for hemorrhoids or other proctological conditions.

[0009] Various cooling bandages are known from the prior art. These are primarily those in which a flat cooling pack is placed across the entire surface of an absorbent compress on the side facing the body. The cooling pack thus cools the perineal area. A disadvantage of this method is that leaking bodily fluid collects on the cooling pack. This can cause discomfort and also promote bacterial growth.

[0010] Furthermore, cooling bandages have become known in which the cooling pouch is positioned on the side of the compress facing away from the body. Here, any infectious bodily fluids that leak out are effectively absorbed by the absorbent core. However, a disadvantage is that, due to the good insulating properties of the cellulose-like absorbent core, the cooling effect is very weak.

[0011] It is therefore the object of the present invention to provide a cooling bandage, in particular for the postpartum period, which improves healing, especially in the perineal area and especially in the vaginal and perineal area.

[0012] The problem is solved by cooling bandages according to the invention, having the features of claim 1 and also claim 2. Preferred further developments and embodiments of the invention will become apparent from the general description and the description of exemplary embodiments.

[0013] The cooling bandage according to the invention is particularly suitable for use during the postpartum period. It comprises at least one substantially planar absorbent core designed to absorb bodily fluids. The cooling bandage also comprises at least one cooling unit, preferably bag-like, which contains at least one cooling medium and has at least a partially flexible and liquid-impermeable wall. In its intended use, the cooling unit is arranged on the side of the absorbent core facing the body. Furthermore, a shaped element is arranged at least partially between the cooling unit and the absorbent core, so that escaping bodily fluid can drain away, particularly directly at the cooling unit, and be channeled into the absorbent core.

[0014] Another cooling bandage according to the invention is particularly suitable for postpartum use. It comprises at least one substantially planar absorbent core designed to absorb bodily fluids. The cooling bandage also comprises at least one cooling unit, preferably bag-like, which contains at least one cooling medium and has at least a partially flexible and liquid-impermeable wall. In its intended use, the cooling unit is arranged on the side of the absorbent core facing the body. Furthermore, at least one opening is provided in the cooling unit, which connects the body-facing side to the absorbent core. Preferably, escaping bodily fluid can be channeled through the cooling unit (indirectly or preferably directly) to the absorbent core.

[0015] The invention has many advantages. A significant advantage is that it enables effective and, in particular, direct cooling of the perineum, especially the genital and perineal areas. Simultaneously, leaking bodily fluids can be absorbed by the suction device.

[0016] The cooling unit can thus be positioned directly at the wound or injured area. The shape of the unit or the opening ensures that body fluid is efficiently channeled into the absorbent core and does not accumulate on the cooling unit.

[0017] The molded unit preferably allows the cooling unit to be advantageously in contact with the perineum in the central area. Simultaneously, any escaping infectious body fluid can preferably be drained laterally. The opening allows body fluid to pass through the cooling unit into the absorbent core. Overall, this supports and promotes the healing of the injured perineum. The molded unit, in particular, achieves an idealized linear contact of the cooling bag along its longitudinal axis.

[0018] The absorbent core is preferably designed as a flat body. Its length and width are preferably significantly greater than its thickness. The absorbent core is preferably designed as an absorbent compress and comprises, in particular, cellulose and / or another preferably absorbent material. The absorbent core may preferably comprise several sub-bodies. The cooling unit may, in particular, be designed as a cooling bag.

[0019] Both requirements, cooling and absorption of infectious body fluid, are advantageously enabled by the cooling bandages according to the invention.

[0020] The cooling bandage is specifically designed as a single-use cooling bandage and, in particular, as a cold pack, which is regularly used only once and not multiple times. This effectively prevents reinfection, especially from germs, bacteria, and / or viruses. It also meets the highest hygiene standards.

[0021] Overall, the cooling bandages according to the invention improve healing in the perineal area in the case of injuries, particularly during the postpartum period.

[0022] Preferably, the cooling medium of the cooling unit comprises at least two components that can react endothermically with each other to provide cooling. It is also possible that the components of the cooling medium are separated from each other by at least one thin membrane when the cooling pad is not in use. The components can be at least partially in liquid form or at least partially in solid form. In particular, at least one component can be at least partially in the form of a gel, gel-like substance, gel-like mass, or granules.

[0023] Reaction temperatures for the endothermic reaction are preferably above the freezing temperature and preferably below 20°C and particularly below 15°C.

[0024] In particular, the cooling medium comprises at least water and at least urea as components. Advantageously, at least one component is formed by urea granules.

[0025] Furthermore, water as a component can also preferentially react at least partially endothermically with ammonium nitrate, urea, and / or calcium ammonium nitrate as a second component.

[0026] The membrane is, in particular, at least partially bladder-shaped and / or at least partially spherical. A component of the cooling medium, which preferably also substantially comprises water, is at least partially separated from the other components by the membrane, which is particularly bladder-shaped, when not in use.

[0027] Furthermore, the components may also include other reactants. The list presented here is only an example and is not exhaustive.

[0028] The membrane is preferably designed to be so thin-walled that it can be ruptured, for example, by a kinking motion of the cooling bandage or by kinking and / or, in particular, by other means of mechanical pressure, so that the components of the cooling medium can come into contact for the endothermic chemical reaction. A shaking motion of the cooling bandage and, in particular, the cooling unit, can promote the mixing of the components of the cooling medium throughout the entire volume of the cooling unit. Thus, the endothermic reaction preferably takes place within the entire cooling unit. The endothermic chemical reaction can be activated, in particular, by a catalyst. The catalyst can be present as a solid or even as a miscible component within the cooling unit.

[0029] The volume of the cooling unit, and in particular the partial volumes encompassed by the components in the unused state, are advantageously designed for a cooling duration, i.e., a reaction duration of at least 15 minutes, and particularly between 0.5 h and 2 h. In particular, the cooling duration is preferably at least approximately 1 h. Furthermore, the cooling duration can also extend up to 3 h or more.

[0030] During the endothermic reaction, the cooling unit typically maintains a temperature between approximately 0 °C and 20 °C. Advantageously, the cooling unit operates at a temperature between approximately 5 °C and 15 °C. A temperature of approximately 10 °C is particularly advantageous. This effectively prevents, or even eliminates, the risk of hypothermia of the perineum, which can impede healing. Simultaneously, the chemical reaction provides a particularly long-lasting cooling effect.

[0031] The cooling bandage, and in particular the cooling unit, does not need to be chilled separately in a refrigerator before use. The endothermic chemical reaction allows for advantageous control of the cooling and heat dissipation in the perineal area. The self-cooling properties also make storage requirements particularly minimal. The endothermic reaction and the self-cooling effect of the chemical reaction result in a particularly reliable and reliable application of the cooling bandage.

[0032] The cooling medium is, in particular, at least partially in the form of a gel, paste, granules, and / or liquid. Specifically, the components are at least partially in the form of a gel, paste, and / or liquid. Furthermore, the cooling medium can also consist of water or a cooling gel. It is also possible for the cooling medium to comprise at least a portion of urea granules. This advantageously ensures that the cooling unit with its flexible wall can adapt particularly well to the body, and especially to the perineum, and can distribute itself advantageously within the cooling unit.

[0033] The cross-section of the mold unit is preferably designed as a circular segment. Furthermore, the cross-section of the mold unit can also preferably be a square, triangle, trapezoid, or other quadrilateral shape. In any case, rounded corners are advantageous.

[0034] Particularly preferably, the maximum height of the molded unit corresponds to between approximately 5% and 85%, and especially between approximately 10% and 70%, and preferably between approximately 20% and 50%, of the maximum overall height. It is particularly advantageous for the maximum height to correspond to approximately 25% of the maximum overall height of the cooling bandage. The maximum height of the molded unit ensures that the escaping body fluid is advantageously channeled into the absorbent core or can be advantageously channeled laterally. The cooling unit can advantageously cool the perineal area directly.

[0035] This effectively prevents the accumulation of body fluid within a trough-shaped recess of the cooling unit.

[0036] The molding unit is particularly preferably arranged along at least a section of a longitudinal axis of the cooling bandage. Advantageously, the molding unit is positioned centrally between the absorbent core and the cooling unit, particularly when viewed across the width of the cooling bandage. This advantageously allows for a uniform drainage of body fluid laterally to both sides. Furthermore, the molding unit ensures that the cooling unit is pressed particularly well against the perineum in the relevant area.

[0037] Preferably, the molding unit has a length between 20% and 100% of the maximum length of the cooling unit. In particular, the molding unit has a length of approximately 50% of the maximum length of the cooling unit.

[0038] Preferably, the forming unit has a width between 5% and 50% of the maximum width of the cooling unit.

[0039] In a particularly advantageous embodiment, the molding unit comprises at least a portion of an absorbent material. It is especially advantageous for the molding unit to comprise the same material, particularly a cellulose-like material, as the absorbent body, and in particular to consist entirely of it. Furthermore, the absorbent body can also comprise a different absorbent material. To maintain the molding properties of the molding unit, the material in this case can be pressed or compacted to a particularly high density.

[0040] Advantageously, the molding unit can be at least partially integrated with and / or formed on the absorbent body. This advantageously maximizes the absorption of body fluid. Despite this, the molding unit can still be flexible and at least partially yielding.

[0041] In a particularly advantageous embodiment, the mold unit includes a reinforcing element, at least in some sections. Advantageously, the reinforcing element is formed at least in some sections of the mold unit. The reinforcing element is made of metal and / or plastic. The reinforcing element advantageously improves the dimensional stability of the mold unit while simultaneously ensuring flexibility. The length and width of the reinforcing element can be significantly smaller than the mold unit itself.

[0042] The cooling unit advantageously features a seam area that circumferentially encircles at least part of the outer surface. Advantageously, the cooling unit is designed as at least one foil bag that has at least one seam circumferentially encircling at least part of the surface and / or a seam area that circumferentially encircles at least partially. In particular, the seam area is at least partially designed as a welded seam. Designing the cooling unit as a foil bag is particularly cost-effective. Furthermore, foil bags can be advantageously manufactured, filled, sealed, and / or packaged in a sterile and automated manner, particularly easily and cost-effectively. The foil bag is preferably tear-resistant and, in particular, especially durable. Thus, the foil bag has a particularly robust and resistant flexible wall. The welded seams can withstand particularly high forces, so that the cooling bag cannot burst, even under high stress.

[0043] In particular, no or only minimal amounts of cooling medium are present in the preferably welded seam area, resulting in a minimal height or thickness of the cooling unit in the seam area. The seam area is especially advantageous for draining and removing any escaping body fluid.

[0044] Advantageously, at least one drainage channel is formed on the cooling unit, which extends into the cooling unit in a finger-like manner and preferably into a central area of ​​the cooling unit. The formation of the drainage channel can advantageously be achieved and / or supported, at least in part, by varying the width of the weld area. In particular, a drainage channel is formed and / or enabled by a finger-like welding of the weld area.

[0045] The drainage channel facilitates the lateral drainage and transfer of body fluid into the absorbent core. In particular, the drainage channel directs body fluid away from a perineal wound into the absorbent core, thus supporting healing.

[0046] In a particularly advantageous embodiment, at least one drainage channel extends substantially transversely into the cooling unit. The transverse extension of the drainage channel is especially advantageous in allowing body fluids, particularly those escaping along the longitudinal axis of the cooling unit, to be drained, preferably laterally and especially directly, into the suction body.

[0047] It is particularly advantageous to have the cooling medium positioned and / or located directly adjacent to the drainage channel. This allows the cooling unit to also advantageously cool the body areas where the drainage channel is located. This maximizes the available cooling surface area of ​​the cooling unit.

[0048] Advantageously, at least 2 to 20 drainage channels are provided on at least one longitudinal side of the cooling unit. This advantageously supports or ensures improved drainage of escaping body fluid into the suction body along the entire longitudinal axis.

[0049] In a further advantageous embodiment, drainage channels are formed symmetrically to each other on both longitudinal sides. In another advantageous embodiment, drainage channels are formed offset from each other or advantageously asymmetrically to each other and / or, in particular, to the longitudinal axis on both longitudinal sides. This allows the drainage of body fluid to be optimized locally at the cooling bandage. At points where a particularly large amount of body fluid is expected, several drainage channels can preferably be arranged, while at other points where little body fluid is expected, fewer drainage channels are formed.

[0050] The symmetrical or asymmetrical design of the drainage channels can also improve wearing comfort. For example, the drainage channels can be advantageously positioned directly at points on the cooling bandage that arise from the bandage's wear and shaping against the body, or where they might be particularly beneficial. Ideally, at least one cooling finger should be formed between two drainage channels. This optimizes the use of the cooling surface and volume of the cooling unit. The areas of the perineum near the drainage channels are also effectively cooled. This contributes to improved healing, especially in these areas.

[0051] The cooling unit has at least one opening for passage. This opening creates a direct connection from the body-facing side to the suction body. This advantageously ensures and / or facilitates the direct drainage of any escaping body fluid. Furthermore, the function and cooling effect of the cooling unit are not, or only minimally, affected, thus maintaining an optimal balance between cooling and the ability to drain body fluid.

[0052] In a particularly advantageous embodiment, at least one opening is formed at the seam of the cooling unit. This advantageously creates a connection between the body-facing side of the cooling unit and the suction body in the seam area. Any escaping body fluid can preferably be drained directly into the suction body.

[0053] In particular, the opening is essentially oval and / or at least partially circular. Both shapes are especially advantageous for facilitating the flow of body fluid to the suction element.

[0054] Preferably, the absorbent core encloses and / or surrounds the cooling unit, at least partially, in a U-shape along at least one longitudinal side. This advantageously allows for optimal placement of the cooling bandage directly against the perineum. The absorbent core advantageously rests directly against a body area, thus also forming a lateral barrier against leaking body fluid. It is particularly advantageous that at least one width of the cooling bag is less than the width of the absorbent core. The ratio of the width of the absorbent core to the width of the cooling unit in the assembled state of the cooling bandage is preferably between 105% and 120% of the maximum width of the cooling bandage. Particularly preferably, the ratio is approximately 110%.

[0055] The cooling bandage preferably comprises at least one sheath unit. Advantageously, the sheath unit encloses at least the absorbent core and at least the cooling unit, at least partially. Preferably, the sheath unit is designed, at least partially, as a sheathing tube, which is mechanically sealed at its ends to the cooling bandage, for example, by gluing or embossing. The sheath unit advantageously serves to at least partially secure the cooling unit, the forming unit, and the absorbent core in their relative positions. Advantageously, the sheath unit ensures that the cooling unit is positioned on the side of the absorbent core facing the body. Furthermore, the sheath unit facilitates easy handling, even when the absorbent core is saturated or filled with body fluid.

[0056] In a further advantageous embodiment, the casing unit is at least partially liquid-permeable. For this purpose, the casing unit can at least partially comprise a liquid-permeable material. The casing unit particularly comprises cellulose and / or an equivalent absorbent material that is at least partially liquid-permeable.

[0057] Advantageously, the outer casing is at least partially made of an absorbent material. Preferably, the outer casing comprises at least a portion of an absorbent material. This allows even small and / or minute amounts of (infectious) body fluid to be absorbed and preferably drawn into the absorbent core. The absorbent material also allows body fluid to be absorbed, particularly where the cooling bandage rests against the body and the perineal area. This significantly improves hygiene. The outer casing is preferably made of or comprises a nonwoven fabric.

[0058] Preferably, the flat, absorbent body has at least partially rounded corners. It is particularly advantageous if at least the cooling unit has at least partially rounded corners. In particular, the radius of the rounded corners extends over at least a quarter or approximately half the width of the cooling band. Smaller radii are also possible.

[0059] In particular, the cooling bandage has an oval shape, at least in sections, due to the rounded corners of the absorbent body and / or cooling unit.

[0060] The rounded corners, in particular, provide greater comfort when inserting the pad into underwear, mesh pants, and other pad holders. The cooling pad also offers an improved fit. Even with significant bending of the pad, the rounded corners do not protrude from the body, skin, or perineum, resulting in an optimal fit.

[0061] In an advantageous embodiment, the cooling bandage comprises at least one liquid-tight barrier layer. The liquid-tight barrier layer is preferably arranged on the outer surface of the cooling bandage facing away from the body, directly adjacent to the absorbent core and / or the outer casing. The barrier layer is at least partially liquid-tight. Preferably, the barrier layer is designed, at least in sections, as a moisture-resistant mat. It is particularly advantageous for the barrier layer to be designed as a plastic film arranged on the underside of the absorbent core. The barrier layer is preferably glued in place. The barrier layer can also be arranged as an insert between the absorbent core and the outer casing. Advantageously, the liquid-tight barrier layer prevents any body fluid from escaping from the absorbent core on the side facing away from the body. This advantageously prevents contamination of clothing and / or other body parts.A risk is minimized. In particular, infectious bodily fluids can be effectively kept away from other parts of the body. Furthermore, the fluid-tight barrier layer advantageously facilitates the drainage and / or dispersal of bodily fluids to a central area of ​​the absorbent core and / or to the sides of the absorbent core. The spread of germs, bacteria, and / or viruses is preferably prevented or at least significantly reduced.

[0062] Advantageously, the cooling bandage includes at least one adhesive strip, which is located on the outer surface of the bandage facing away from the body. The adhesive strip allows the cooling bandage to be preferably attached directly to or affixed to clothing, such as underwear, trousers, fishnet stockings, briefs, and / or the like. This advantageously provides improved adhesion of the cooling bandage to the clothing, particularly in the perineal area. The cooling bandage is less likely to slip, or may even remain in place. This also advantageously ensures the absorption of body fluids and the simultaneous cooling of a wound, even during movement.

[0063] The cooling unit comprises, in particular, between at least 2 and 200 openings. It is especially preferred that the cooling unit comprises between 2 and 50, or between 3 and 5, or 10 openings. Advantageously, the openings result in short transport and drainage paths for conveying the infectious body fluid into the absorbent core. This significantly reduces the likelihood of a backflow of body fluid.

[0064] The openings are advantageously designed within a central area of ​​the suction body. Preferably, at least 25%, 40%, 55%, 70%, or even 85% of the openings are arranged and / or formed in the central area. In particular, the cooling bandage and / or the cooling unit can be divided into a central area and a surrounding edge area. The edge area advantageously extends inwards from the edge of the cooling bandage and comprises, in particular, at least approximately 5% or even 10% of the width of the cooling bandage or the cooling unit. Advantageously, however, the edge area comprises less than 50% of the total width of the cooling bandage. In particular, the width of the edge area is approximately 25% of the width of the cooling bandage.

[0065] Preferably, a cooling bandage according to the invention has a width between approximately 40 mm and approximately 180 mm. In particular, a cooling bandage has a width between approximately 100 mm and approximately 140 mm. In particular, a cooling bandage has a width of approximately 120 mm.

[0066] Advantageously, a cooling bandage according to the invention has a length between approximately 150 mm and approximately 660 mm. Advantageously, a cooling bandage has a length between approximately 450 mm and approximately 200 mm. Particularly preferably, a cooling bandage has a length between, in particular, 250 mm and 360 mm. In particular, a cooling bandage according to the invention has a length of approximately 330 mm.

[0067] Advantageously, a cooling bandage according to the invention has a total height between approximately 5 mm or 10 mm and approximately 50 mm. Advantageously, a cooling bandage has a total height between approximately 15 mm or 20 mm and approximately 40 mm. Preferably, a cooling bandage according to the invention has a total height of approximately 30 mm (+ / - 5 mm).

[0068] In a particularly advantageous embodiment, the cooling bandage comprises at least one active ingredient section, which serves to absorb and transfer at least one active ingredient to the body or perineum. The active ingredient primarily serves to support the healing process. The active ingredient section can be incorporated as a single unit into the cooling unit or formed on it. The active ingredient section can also advantageously be arranged or applied as a separate layer on the cooling unit. It is particularly advantageous to have at least one separating layer, which is formed as a thin and, in particular, multi-layered layer. It is advantageous for the separating layer to be at least partially permeable and / or, in particular, completely impermeable to the active ingredient. This preferably prevents the active ingredient, which may be present, for example, in a cream, from being absorbed into the absorbent core. This advantageously supports healing.

[0069] Further advantages and features of the present invention will become apparent from the exemplary embodiments, which are explained below with reference to the accompanying figures.

[0070] The figures show: Fig. 1 a purely schematic sectional view of a cooling bandage according to the invention; Fig. 2 a purely schematic top view of a cooling bandage according to the invention; Fig. 3 a purely schematic top view of another cooling bandage according to the invention.

[0071] Fig. Figure 1 shows a purely schematic sectional view through a cooling bandage 1 according to the invention, which is designed here in particular to support the healing of an injured perineum during the postpartum period.

[0072] The absorbent core 2 is arranged on the side 19 facing away from the body. A cooling unit 5 is arranged on the base 3 of the absorbent core 2, on the side 20 facing the body. A forming unit 9 is arranged between the cooling unit 5 and the absorbent core 2. The absorbent core 2 is designed as an absorbent cellulose compress. The forming unit 9 can also be made of compressed cellulose. The forming unit 9 has a maximum height 10 of approximately 25% (specifically between 20% and 35%) of the maximum overall height 11 of the cooling bandage 1. The maximum overall height 11 of the cooling bandage 1 is approximately 30.4 mm. The cooling bandage has a width of approximately 121 mm.

[0073] The forming unit 9 is positioned centrally along the longitudinal axis 16 of the cooling bandage 1, so that any escaping body fluid 4 is preferably directed laterally towards the absorbent core 2. This preferably ensures that the perineum, in particular, can be cooled preferably in the center. At the same time, the forming unit 9 ensures that the escaping infectious body fluid 4 can advantageously be directed laterally into the absorbent core 2, thus improving the conditions for healing, preferably in the perineal area.

[0074] The cooling unit 5 comprises a cooling medium 6, which consists of two components. In the present embodiment, one component 30 is water 30, while the second component 31 comprises urea granules 31. Both components react in an endothermic reaction, resulting in a cooling effect. The cooling temperature is approximately between 4 °C and 10 °C. This advantageously prevents subcooling.

[0075] In its unused state, the two components within the cooling unit 5 are separated by a thin membrane 32. Here, the membrane 32 is bubble-shaped. By a bending motion, e.g., primarily in the transverse and / or longitudinal direction, the thin membrane 32 is intentionally ruptured. The two components 30, 31 can then mix to form a gel. In this process, the two components 30, 31 react with each other. This is an endothermic reaction, which only occurs if sufficient heat is supplied from the outside. Here, the heat is preferentially drawn from the perineum. Consequently, the perineum is particularly cooled.

[0076] The cooling unit 5 is designed here as a welded foil pouch. The cooling unit 5 has a flexible wall 7, which can easily adapt to the body in the perineal area. This ensures an optimal cooling effect. The foil pouch has a welded seam.

[0077] In the sectional view, 16 drainage channels 15 are formed laterally along the longitudinal axis. These drainage channels 15 ensure particularly efficient lateral drainage of body fluid towards the absorbent body 2. The welded seam area 13 is wide in the region of the drainage channels 15. This influences the shape of the flexible wall 7, which is very steep in this area. The infectious body fluid 4 is advantageously drained laterally along the drainage channels 15.

[0078] On the left side, an additional opening 17 is formed within the seam area 13. This significantly shortens the transport path of the body fluid 4 compared to the embodiment without openings 17. The infectious body fluid 4 can be more effectively directed into the interior of the absorbent body 2.

[0079] The absorbent core 2 surrounds the cooling unit 5 in a U-shape 24 along its longitudinal sides 27. This improves the absorption of laterally drained body fluid 4 by the absorbent core 2. It also ensures that the absorbent core 2 lies directly against the skin around the perineum. This prevents body fluid 4, which leaks within the absorption area, from flowing past the cooling bandage 1 and the absorbent core 2.

[0080] On the side 19 facing away from the body, a fluid-impermeable barrier layer 21 is present. The barrier layer 21 is designed as a moisture-resistant mat. The barrier layer 21 prevents body fluid 4 from escaping from the cooling bandage 1 and, in particular, the absorbent body 2, even when the absorbent body 2 is completely filled or saturated. Furthermore, the barrier layer 21 helps to distribute any potentially infectious body fluid 4 within the absorbent body 2 and to direct it into the interior of the absorbent body 2 and to the absorbent form 9.

[0081] A casing unit 23 is present, which encloses the absorbent core 2, the forming unit 9, and the cooling unit 5. The casing unit 23 consists of an absorbent nonwoven fabric in the form of a tube. Body fluid 4 can be drawn through the nonwoven fabric into the interior of the cooling bandage 1. The casing unit 23 primarily serves to facilitate handling when the absorbent core 2 is completely filled and saturated with body fluid 4. Furthermore, the casing unit serves to clearly define the position of the cooling unit 5 relative to the absorbent core 2.

[0082] The cooling bandage 1 has an adhesive strip 22 on its underside. This adhesive strip 22 can be used to secure the cooling bandage 1, for example, inside underwear. This prevents the cooling bandage 1 from slipping during movements such as walking or carrying a child.

[0083] Fig. Figure 2 shows a top view of the cooling bandage 1 according to the invention. Fig. 1. The suction body 2 has a substantially rectangular base 3. The cooling unit 5 with the cooling medium 6 is arranged on the suction body 2. The suction body 2 encloses the cooling unit 5 along its longitudinal sides 27.

[0084] The cooling bandage 1 has a length of approximately 330 mm. In the center of the absorbent core 2 and the cooling unit 5, the shaped unit 9 is formed along a longitudinal section 8 of the longitudinal axis 16. The shaped unit 9 additionally features a reinforcing element 12, which is formed here by a narrow, elongated plastic element. The reinforcing element 12 improves the shape and the cooling effect of the cooling unit 5, particularly along the longitudinal axis 16 in the center of the cooling bandage. This allows the perineum to be cooled preferentially in the area of ​​an injury. Simultaneously, body fluid 4 can be drawn laterally from the shaped unit 9 into the absorbent core 2.

[0085] To facilitate the drainage of infectious body fluid 4, drainage channels 15 are provided. These channels extend transversely to the longitudinal axis 16 into the cooling unit 5. This allows body fluid 4, which emerges directly from the center of the cooling bandage 1, to be advantageously drained laterally into the drainage channels 15. A total of ten drainage channels 15 are provided, arranged symmetrically to the longitudinal axis 16. A cooling finger 26 is formed between each pair of drainage channels 15. The cooling fingers 26 ensure optimal cooling, particularly between the drainage channels 15. In the upper region, the drainage channels 15 also feature 3 openings 17 in the seam area. These openings 17 are circular. The openings 17 ensure direct drainage of the body fluid 4 into the absorbent core 2.Through the active ingredient section 29 (dot-dot line), an active ingredient can be advantageously transferred to the perineum, thereby improving and accelerating the healing process.

[0086] Fig.Figure 3 shows a purely schematic top view of another cooling bandage 1 according to the invention. The cooling bandage has rounded corners 18. This allows for improved adaptation of the shape of the absorbent core 2 and the cooling unit 5 to the perineum. Within the central area 25, a plurality, a total of 17, of openings 17 are provided. Complementary to the central area 25 (dashed line) is the edge area 28. The edge area 28 has a thickness of approximately 10% of the maximum width of the cooling bandage. The openings 17 are all arranged within the central area 25 and allow advantageous and direct drainage of body fluid 4 leaking from the perineum into the absorbent core 2 of the cooling bandage 1. This improves the healing of injuries in the perineal area.

[0087] The cooling bandage is preferably designed as a cold pack. The cooling bandage addresses the need for relief from perineal complications after childbirth. The self-cooling cold pack can essentially perform at least two essential functions: it can draw infectious discharge away from the wound and, with its pleasant cooling effect, promote rapid recovery. Strict hygiene standards must be observed.

[0088] The cooling bandage 1 combines the advantages of a gel compress with those of a bandage, making it particularly hygienic for use in perineal complications.

[0089] For medical professionals, addressing hygienic wound care relatively early on can be part of an effective therapy. For example, right after birth.

[0090] Cooling is a good option in this regard. The positive effects of cold application have been known since the time of Hippocrates: - Help with pain relief. - Possibility of reducing swelling, thus lowering cell metabolism. Inflammation can be significantly reduced. - It is possible that the administration of painkillers can be significantly reduced.

[0091] In practice, the application of cold is handled very differently, with potential consequences for the success of the treatment and the sensitive issue of hygiene. Gel compresses only maintain the appropriate temperature briefly: initially, they are too cold and can damage already stressed skin; later, they warm up too quickly. The traditional method of using ice packs or similar products can no longer be recommended for reasons of hygiene and patient safety.

[0092] The cooling bandage according to the present invention utilizes the medical effect of cold and is particularly hygienic and safe to use. Compared to traditional methods, the advantages are obvious: - self-cooling due to a particularly safe endothermic reaction. - in particular, no refrigerator is necessary - the cooling bandage, for example, is ready for immediate use in three simple steps. - constant temperature - no danger from excessively cold compresses - reliably absorbs even heavy postpartum bleeding like a large pad - with the comfort of, for example, a maxi pad. - Usable only once and therefore particularly hygienic. - in particular, the ease of use relieves the burden on staff. - also useful for other applications such as hemorrhoids or proctological conditions.

[0093] The cooling bandage combines hygienic well-being for the woman with, above all, high product and process safety for the nursing staff.

[0094] The cooling bandage combines the advantages of a gel compress with those of a highly absorbent pad - with particularly good hygiene.

[0095] Besides the medical and hygienic benefits for the woman, the cooling bandage also offers tangible advantages for the professional user. Hygiene is a sensitive issue. The cooling bandage is preferably for single use only and therefore does not require extensive preparation for reuse.

[0096] The cooling bandage 1 can be disposed of simply like a liner. The product can be packaged in a highly sterile manner, ensuring it remains safe and hygienic regardless of the application.

[0097] The cooling bandage 1 is advantageously self-cooling. This eliminates the need for refrigeration, saving both time and money. Handling is as simple as with a standard pad. This reduces stress for nursing staff, who can rely on the bandage's sterility at all times. As a result, processes in maternity wards and birthing centers become more efficient and hygienic – benefiting both patients and staff.

[0098] The Cooling Bandage 1 is advantageous primarily for hygienic reasons, being designed as a single-use product. The Cooling Bandage 1 is an economical item that, in addition to its medical and hygienic benefits, also promotes well-being. Furthermore, the Cooling Bandage 1 is also efficient and safe for postpartum care following home births.
