The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

The technical solution of the present disclosure is explained in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The cold application according to the embodiments of the present disclosure may be any structure that can be applied to an affected part and can achieve a cold application effect, where the cold application may be used for cooling only and applying a corresponding medicine, and specifically, the cold application may be a cooling patch, or a plaster patch, and the like, regardless of the application scenario and the application, without departing from the scope of the embodiments of the present disclosure.

Referring to fig. 1 and 2, the cold compress patch includes: the adhesive comprises an adhesive substrate 3, release paper 2, a slow-permeation layer 6, a sealing frame 4, an anti-overflow frame 1 and a dressing layer 5.

The release paper 2 covers the first side of the adhesive substrate 3, which can be understood as the lower side shown in fig. 1, and the corresponding second side of the adhesive substrate 3 can be understood as the side opposite to the release paper 2, which is the upper side shown in fig. 1.

The partial surface detachable from type paper 2 paste in the first surface 31 of viscose substrate 3 first side, wherein paste can adopt the viscose to realize, and in a concrete scheme, can not take the viscose from type paper 2, viscose substrate one side takes the viscose, and the cold compress is mainly fixed in the affected part by the viscose substrate, and wherein, the surface that sets up the viscose is first surface 31 promptly. The single-side gluing process is relatively simpler, and has the positive effect of being convenient to manufacture.

The sealing frame 4 and the dressing layer 5 are arranged between the release paper 2 and the second surface 32 of the first side of the viscose substrate 3, the dressing layer 5 is arranged in an area enclosed by the sealing frame 4, and further, the sealing frame 4 is distributed on the periphery of the dressing layer 5.

The slow permeation layer 6 is laid on one surface of the dressing layer 5 far away from the viscose substrate 3.

The permeation-retarding layer 6 is arranged on one side of the dressing layer 5 and the sealing frame 4 far away from the adhesive substrate 3, and further between the release paper 2 and the dressing layer 5 and between the release paper and the sealing frame 4, taking fig. 1 as an example, the permeation-retarding layer 6 is arranged on the lower side of the dressing layer 5 and the sealing frame 4.

In one specific embodiment, the surface of one side of the permeation-retarding layer 6 can be connected with the dressing layer 5 and the sealing frame 4, and the surface of the other side can be connected with the release paper 2, and in other embodiments not shown, at least one of the positions between the permeation-retarding layer 6 and the dressing layer 5, between the permeation-retarding layer 6 and the sealing frame 4, between the permeation-retarding layer 6 and the release paper 2, and the like, may also be provided with other structural layers.

The slow-permeation layer can be understood as a structural layer for permeation of the dressing, and specifically, the functions of guiding, slow flow and the like of the dressing can be realized. The permeation-retarding layer can be, for example, a denser nonwoven fabric in which an embossing pattern can be provided, and in one example, the permeation-retarding layer can be provided with embossing, thereby conforming to the skin and reducing the possibility of lateral flow of the dressing (e.g., gel).

In the above scheme, the slow-permeation layer is arranged outside the dressing layer, so that the dressing layer can be prevented from directly contacting the skin surface of a human body or an animal body, and the permeation of the dressing is slowed down. Meanwhile, when the human body or the animal body moves, the dressing and the skin are prevented from moving relatively and leaking out of the sealing frame transversely, and the adhesion stability between the adhesive substrate and the skin is further guaranteed.

In the embodiment of the present disclosure, the outer edge of the permeation retarding layer 6 is connected to the sealing frame 4. The outer edge of the permeation-retarding layer 6 is defined as the portion adjacent to the outer periphery and connected to the sealing frame 4, and may or may not be flush with the outer periphery of the sealing frame 4.

The above-mentioned outer periphery is understood to be an outer periphery in the cold application transverse direction, which is understood to be a direction perpendicular to the first side to the second side of the adhesive substrate 3.

One part (for example, the outer ring frame part 11) of the spill proof frame 1 covers the partial surface of the sealing frame on the side close to the release paper, the partial surface can be connected with the sealing frame, and the other part (for example, the inner ring frame part 12) covers the outer edge of the permeation retarding layer 6.

The anti-overflow frame 1 is made of impermeable material which is impermeable to dressing. In a specific example, the anti-overflow frame may include: at least one of non-permeable materials such as a pearlized film and a plastic film.

In the above solution, the possibility of lateral penetration of the dressing, i.e. the possibility of lateral spillage of the dressing (e.g. gel) under pressure, is further reduced by the spill-proof border, which is impermeable to the dressing.

In one embodiment, referring to fig. 1 to 7, the anti-overflow frame 1 includes an outer frame portion 11 in a closed loop, the outer frame portion 11 surrounds the outer periphery of the permeation retarding layer 6, and the outer frame portion 11 is connected to a side of the sealing frame 4 away from the adhesive substrate 3, which is connected to a lower side of the sealing frame 4 as shown in fig. 1 and 3.

The anti-overflow frame 1 further comprises an inner ring frame part 12 extending to the inner side of the outer ring frame part 11; the inner rim portion 12 covers the outer edge of the permeation-retarding layer 6.

Through outer circle rim portion 11, can help reducing the dressing and spill over from slowly permeating layer and sealed frame 4 between, through inner circle rim portion 12, can help guaranteeing to slowly permeate layer 6, sealed frame 4 and the inseparable cooperation between the anti-overflow frame 1 on the one hand, and then further reduce the possibility that the dressing spills over through inseparable cooperation, on the other hand, also can form the sheltering from of anti-overflow on the surface of slowly permeating layer 6.

At the same time, the dressing (e.g. gel) when pressed spills out from the surface of the exudate layer in addition to sideways. When a non-woven fabric material is used as the permeation-retarding layer, the non-woven fabric has hydrophilic property, so that the overflowing gel is diffused to the periphery along the non-woven fabric and finally overflows in the peripheral direction. The outer ring frame part 11 and the inner ring frame part 12 can also effectively prevent or reduce the dressing which is diffused outwards along the permeation-retarding layer from further overflowing outwards.

In addition, when using cold application, slowly ooze the layer and can remain with the anti-overflow frame, and then, still can help fixing the position of slowly oozing the layer relative to sealing frame, dressing substrate through the anti-overflow frame. Avoid or alleviate dressing overflow that the removal of slowly oozing layer brought.

In a further aspect, referring to fig. 3 to 7, the spill-proof frame further includes an inner ring extending portion 13 extending inside the inner ring frame portion 12. The inner-ring extending portion 13 can be understood as a structure extending from the inner-ring frame portion 12 toward the center.

In the example shown in fig. 6, both the inner ring extension portion 13 and the inner ring frame portion 12 are annular, and in other examples, the inner ring extension portion 13 and the inner ring frame portion 12 may not be annular, and for example, a plurality of inner ring extension portions 13 (or inner ring frame portions 12) may be uniformly distributed in the circumferential direction of the outer ring frame portion 11.

Wherein, the inner ring extension part 13 is positioned in the dressing layer 5 at the projection area of the permeation-retarding layer 16, which can effectively prevent or reduce the longitudinal permeation of the dressing through the corresponding position of the permeation-retarding layer 16 and further overflow. The longitudinal direction can be understood as the direction from one side surface of the adhesive substrate 3 to the other side surface.

Furthermore, the permeation-retarding layer and the spill-proof rim remain when cold application is used, and furthermore, guiding the dressing to a more concentrated position is also facilitated by the inner loop extension 13.

In one embodiment, the dressing layer 5 may be any structural layer with a dressing, and may be a gel dressing, for example, a gel-like substance, without departing from the scope of the embodiments of the present disclosure. In some embodiments, the dressing layer 5 may also be described as a gel layer.

In one embodiment, referring to fig. 3 to 7, the cold compress patch further includes a release paper easy-to-tear portion 8, the release paper easy-to-tear portion 8 is disposed between the release paper 2 and a third surface 33 of the first side of the adhesive substrate 3, and the third surface 33 is located at the edge of the adhesive substrate 3.

In an embodiment, if the edge of the adhesive substrate 3 has a plurality of edge segments (for example, the edge of the adhesive substrate 3 may be rectangular, and further has four edge segments), then: from easy tearing of type paper portion can set up at arbitrary border section department of many border sections, if the length of each border section is different, then: the release paper easy-tearing part can be arranged at the shorter edge section.

The release paper easy-tearing part can also cover the corresponding whole edge section, thereby being beneficial to the smooth tearing of the whole surface. In other examples, only local positions of the corresponding edge segments may be covered.

If the easy-to-tear part of the release paper is arranged at the corner position (which can be understood as the corner position of the adjacent edge segment), when the release paper is torn, the wrinkles of the soft adhesive substrate can be adhered, which is not beneficial to the next smooth application. Therefore, the easy-tearing part of the release paper can avoid the corner position.

In one embodiment, referring to fig. 3 to 5, the cold compress further includes: a barrier layer 7.

One side surface of the impermeable layer 7 is connected with the second surface 32 of the first side of the adhesive substrate 3, and the other side surface of the impermeable layer 7 is connected with the dressing layer 5 and one side of the sealing frame 4 far away from the release paper 2.

The impermeable layer 7 can be understood as any structural layer that can prevent the dressing from flowing to the outside, namely: the impermeable layer 7 is made of impermeable materials impermeable to dressing; in particular, the barrier layer 7 may be an inelastic barrier mat (e.g., a pearl fabric may be used).

In one embodiment, the adhesive substrate 3 is a diamond mesh surface or a surface made of an elastic material. Furthermore, by virtue of the elastic (or understood deformable) structure, a stretch-adhesive function can be provided; through the rhombic grid surface, rhombic air holes can be provided, the problem that the adhesion effect is reduced due to the fact that the skin is covered with stuffy and sweaty for a long time is solved, and the good adhesion effect is guaranteed.

In one embodiment, the cold compress patch further comprises: and a protective layer 9.

The protective layer 9 covers one side, close to the release paper, of the anti-overflow frame 1, and the projection area of the protective layer 9 on the adhesive substrate 3 completely covers the projection areas of the sealing frame 4 and the dressing layer 5 on the adhesive substrate 3.

The protective layer 9 is made of a non-permeable material impermeable to the dressing, for example, an impermeable material such as kraft paper or plastic film may be used.

Wherein, one side of the protection layer 9 is detachably connected with the anti-overflow frame 4, for example, the connection can be realized by adhesion.

As mentioned previously, the dressing (e.g. gel) when compressed will overflow more from the surface of the exudate layer than laterally. When a non-woven fabric material is used as the permeation-retarding layer, the non-woven fabric has hydrophilic characteristics, so that the overflowing gel diffuses along the periphery of the non-woven fabric and finally overflows in the circumferential direction. Further protection against spillage of the dressing (e.g. gel) can be achieved by a detachable connection (e.g. adhesive) of the protective layer and the spill-proof rim.

In one embodiment, the cold compress further comprises: an easily torn portion of the protective layer;

the protective layer and the anti-overflow frame are detachably adhered, and the part or the whole of the part easy to tear of the protective layer is clamped between the protective layer and the anti-overflow frame. The structural form, the material and the like of the easy-tearing part of the protective layer can be understood by referring to the easy-tearing part of the release paper. The protective layer can be more conveniently torn through the easy-to-tear part of the protective layer. The protective layer tear tab may be, for example, a tear strip or similar structure.

Furthermore, the protective layer can be more conveniently torn through the easy-to-tear part of the protective layer.

When the cold compress patch is used, the release paper can be torn from the easy-tear strip of the release paper, and then the cold compress patch is pasted on an affected part after the protective layer is torn.

In addition, in the solution of the protective layer 9, the joint between the protective layer 9 and the permeation-retarding layer 6 can be flush with the first surface 31 (it can also be understood that the distance between the permeation-retarding layer 6 and the second surface 32 matches the distance between the first surface 31 and the second surface along the longitudinal direction), and further, when the cold compress patch is used, the permeation-retarding layer 6 can be more matched and firmly fixed on the skin surface of the human body or animal body. Further, as shown in fig. 5, the protective layer 9 may make the release paper form a protrusion to the outside.

In order to achieve an effective connection of the layers, the glued surfaces in the structural layers may be, for example: the first surface of the first side of the adhesive substrate 3, the surface of one side of the impermeable layer 7 opposite to the adhesive substrate 3, and the surface of one side of the sealing frame 4 opposite to the adhesive substrate 3.

In the description herein, reference to the terms "an implementation," "an embodiment," "a specific implementation," "an example" or the like means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the disclosure.
