Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plasters, and in particular to a self-heating plaster. Background Art
[0002] Plaster application is one of the methods used externally to treat diseases in my country. It follows the principles of TCM diagnosis and treatment and the efficacy, main indications and meridians of Chinese medicine, fully mobilizes the effectiveness of drugs to coordinate with each other, and forms a large compound of multiple medicines to exert the good effects of the drugs.
[0003] In the survey of the use of plasters on the market, it was found that patients had a lot of negative feedback during use, such as poor plaster adhesion, easy displacement of the plaster and the skin, poor body sensation, etc. In some plasters, especially black plasters, temperature has a promoting and enhancing effect on the body sensation of the product and the release of active ingredients.
[0004] As we all know, black plasters must be heated and softened before use, and then the softened plaster is applied to the affected area of the patient. When heated and softened, for example, candles or hot air from a hair dryer are commonly used; for example, in the winter in the north, the plaster is often placed on a radiator to soften the plaster through heat conduction. These give first-time patients a poor experience and an impression of inconvenience.
[0005] In an existing solution, a plaster is equipped with an electrically heated hot compress patch, and the plaster is heated by the electrically heated hot compress patch. The heating of this solution needs to be connected to a power source, and it cannot be carried 24 hours a day. The use time is affected by the patient's location, which is inconvenient to use. It also has the disadvantages of short constant temperature time and poor safety.
[0006] In another existing scheme, a plaster is equipped with a heating pack that generates self-heating by contact with air, the heating pack is stacked on the back of the plaster, and then the heating pack and the plaster are attached to the skin surface together with medical tape. In this scheme, since the efficacy of the plaster may take many days to slowly play out, and the heating time of the heating pack is limited, some may only be one day or even half a day, and the heating effect cannot be maintained for a long time. At the same time, the use of medical tape for pasting is not beautiful, and it also affects the contact reaction between the heating pack and oxygen. In addition, if the heating pack and the plaster are attached to the skin surface together, both must be taken at the same time, which may cause the plaster that has not fully exerted its efficacy to be removed together with the heating pack, resulting in interruption or waste of efficacy.

[0011] In an implementable solution, the plaster combination layer includes a pearlescent film layer, the outer dimensions of the pearlescent film layer are consistent with those of the plaster layer; the front side of the pearlescent film layer is attached to the back side of the plaster layer, and the back side of the pearlescent film layer is adhered to the front side of the first non-woven fabric layer.
[0012] In an implementable solution, the plaster combination layer includes a silicone oil paper layer, and the outer dimensions of the silicone oil paper layer are consistent with those of the plaster layer; the back side of the silicone oil paper layer is attached to the front side of the plaster layer.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a self-heating plaster patch, including a plaster patch 1 and a heating pack 2; the front side is defined as the side facing the skin when applied, and the back side is defined as the side away from the skin when applied.
[0030] The plaster patch 1 includes a plaster combination layer 11, a first non-woven fabric layer 12, a temperature control layer 13 and a second non-woven fabric layer 14 stacked in sequence; the plaster combination layer 11 includes at least a plaster layer 111 in direct contact with the skin. The front side of the first non-woven fabric layer 12 is adhered to the back side of the plaster combination layer 11, and the edges of the first non-woven fabric layer 12 exceed the edges of the plaster layer 111. The front side of the exceeding part is provided with an adhesive layer 3. The entire back side of the first non-woven fabric layer 12 can be fully provided with adhesive, and the part not covered by the back side of the plaster combination layer 11 is exposed to form an adhesive layer 5 for adhering to the skin. The adhesive layer 5 can be a pressure-sensitive adhesive.
[0031] The front side of the temperature control layer 13 is adhered to the back side of the first non-woven fabric layer 12 . The edges of the first non-woven fabric layer 12 extend beyond the edges of the temperature control layer 13 . No adhesive layer 3 is provided on the back side of the extending portion.
[0032] The front side of the second non-woven fabric layer 14 is adhered to the back side of the temperature control layer 13, and the edges of the second non-woven fabric layer 14 are beyond the edges of the temperature control layer 13, and the front side of the beyond part is not provided with the adhesive layer 3. The back side of the second non-woven fabric layer 14 is provided with an adhesive layer 3 near the edges; the outer dimensions of the heating pack 2 are smaller than the outer dimensions of the second non-woven fabric layer 14;
[0033] The self-heating plaster patch includes a first structural state and a second structural state. In the first structural state, the plaster patch 1 and the heating pack 2 are independent separate structures. In the second structural state, the front side of the heating pack 2 is attached to the back side of the second non-woven fabric layer 14, and the adhesive layer 3 on the edges of the back side of the second non-woven fabric layer 14 is folded up and inward and adhered to the edges of the back side of the heating pack 2.
[0034] See also Figure 1 to Figure 2 It can be seen from the transformation that in the self-heating plaster patch of the present embodiment, the adhesive layer 3 on the edges around the second non-woven fabric layer 14 is folded upward, and the edge of the heating pack 2 can be fixed with the help of the adhesive layer 3 here, so as to achieve the combined state of the heating pack 2 and the plaster patch 1. When the heating pack 2 does not generate enough heat, the adhesive layer 3 on the edge of the second non-woven fabric layer 14 can be uncovered, the used heating pack 2 can be removed, and replaced with a new unused heating pack 2, and then the edge of the heating pack 2 can be fixed with the adhesive layer 3 on the edge of the second non-woven fabric layer 14. It can be seen from this that if the efficacy of the plaster patch 1 lasts for several days, the self-heating plaster patch of the present application can replace the heating pack 2, so that a long period of continuous heating can be ensured by replacing multiple heating packs 2, so that the heating time can cover the efficacy time of the plaster, thereby enhancing the efficacy of the plaster.
[0035] In this embodiment, if Figure 1 and Figure 2 As shown, the plaster combination layer 11 includes a pearlescent film layer 112, and the outer dimensions of the pearlescent film layer 112 are consistent with the outer dimensions of the plaster layer 111. The front side of the pearlescent film layer 112 is attached to the back side of the plaster layer 111, and the back side of the pearlescent film layer 112 is adhered to the front side of the first non-woven fabric layer 12. The pearlescent film layer 112 can be a biaxially oriented polypropylene pearlescent film.
[0036] In this embodiment, if Figure 1 and Figure 2 As shown, the plaster combination layer 11 includes a silicone oil paper layer 113, the outer dimensions of the silicone oil paper layer 113 are consistent with the outer dimensions of the plaster layer 111; the back of the silicone oil paper layer 113 is attached to the front of the plaster layer 111. When in use, the silicone oil paper layer 113 is torn off.
[0037] In this embodiment, if Figure 1 and Figure 2As shown, the plaster combination layer 11 includes a release paper layer 114, and the outer dimensions of the release paper layer 114 are consistent with the outer dimensions of the first non-woven fabric layer 12. The middle position of the back side of the release paper layer 114 is attached to the front side of the silicone oil paper layer 113, and the portion of the edges of the release paper layer 114 that exceeds the edges of the silicone oil paper layer 113 is attached to the portion of the edges of the first non-woven fabric layer 12 that exceeds the edges of the plaster layer 111. When in use, the release paper layer 114 is torn off.
[0038] In this embodiment, if Figure 1 and Figure 2 As shown, the outer dimensions of the heating pack 2 are larger than the outer dimensions of the plaster layer 111. In the second structural state, the periphery of the heating pack 2 wraps the periphery of the plaster layer 111, which is equivalent to the area of the heating pack 2 being larger than the area of the plaster layer 111. The heat dissipated not only softens the paste and improves bioavailability, but also warms the affected area, improves the numbness and coldness, reduces the pain caused by low temperature, improves comfort, and improves patient compliance.
[0039] In this embodiment, if Figure 1 and Figure 2 As shown, the outer dimensions of the temperature control layer 13 are consistent with the outer dimensions of the heating pack 2. In the second structural state, the periphery of the heating pack 2 coincides with the periphery of the temperature control layer 13.
[0040] The temperature control layer 13 may be a medical gauze layer or a sponge pad layer.
[0041] For human skin, the temperature threshold that theoretically causes damage to normal human skin is 44°C. As the temperature rises, the longer the exposure time, the more severe the damage. At 44-51°C, the degree of damage is positively correlated with the contact time, while at temperatures above 51°C, damage can occur in a very short time. If contact is made at 60°C for 1 minute, protein coagulation occurs, causing irreversible skin damage. The degree of skin damage and thermal mortality are related to the contact temperature, contact time, and contact site.
[0042] The self-heating plaster of this embodiment is suitable for the neck, shoulders, lumbar spine and joints, which are more susceptible to heat than soft parts such as the abdomen. Considering the efficacy and safety temperature, the temperature of this utility model should meet the human body safety temperature of 38-44° C. Considering that the product continues to heat for 12 hours, the safety temperature is extremely important to the product, so the experiment is designed to examine the thickness and material of the temperature control layer 13.
[0043] Compare the cases where there is no temperature control layer 13 and the temperature control layer 13 is a medical gauze layer or a sponge pad layer. Use a GPRS temperature and humidity transmitter to measure the temperature of the surface in contact with the skin, and record the heating time, temperature holding time, and temperature range. The experimental design records the heating time when the surface temperature rises to 38°C; records the temperature stability time of 38-44°C; and records the temperature range within the same time. The experimental results are shown in Table 1.
[0044] Table 1 Record of temperature rise in different temperature control layers
[0045]
[0046] According to the results, the temperature control layer 13 is a medical gauze layer (6 layers of medical gauze) which can effectively control the safety temperature not higher than 44°C, has better air permeability and fit than a sponge pad, and is safer than a non-woven fabric used alone. Therefore, the temperature control layer 13 is preferably a medical gauze layer, and a sponge pad layer can be selected as an alternative.
[0047] The combination of the first non-woven fabric layer 12, the temperature control layer 13 (using a medical gauze layer) and the second non-woven fabric layer 14 is closer to the thickness and texture of clothes, and transfers heat safely and effectively. The double-layer non-woven fabric fixes the skin and the heating pack respectively, which is convenient, firm and effective, and improves safety performance.
[0048] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of ridges 21 may be evenly arranged on the back of the heating pack 2, and the area covered by the plurality of ridges 21 does not exceed 1 / 2 of the area of the back of the heating pack 2. Preferably, the area covered by the plurality of ridges 21 may account for 1 / 4 of the area of the back of the heating pack 2. The ridges 21 may be made of silicone.
[0049] The design of the ridges 21 allows air to enter even when blocked and squeezed by clothing and external forces, thereby ensuring uniform heating of the heating pack 2. In the experiment of this embodiment, the coverage of the ridges 21 extends the heating time of the heating pack by 1-2 hours.
[0050] In this embodiment, if Figure 1 and Figure 2 As shown, in the first structural state, the surface of the adhesive layer 3 near the four peripheral edges of the back side of the second non-woven fabric layer 14 can be covered with an easy-tear sticker, which is torn off during use to expose the adhesive layer 3.
[0051] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
