Description

Technical Field

[0001] This invention relates to medical devices, and more particularly to a medicated patch that delivers medication to the human body in a tiered manner. Background Technology

[0002] Medicated patches (commonly known as moxibustion patches) are widely used due to their low price and therapeutic effects on a variety of diseases. A typical moxibustion patch generally consists of a backing layer, a heating layer, and a solid medicated layer (also called a medicated pack). Under storage conditions, they are individually sealed. When used, the patch is opened and applied to the body. Air enters, causing the heating layer (using self-heating technology) to generate heat. The heat passes through the solid medicated layer, allowing the medication to act transdermally on the body, thus producing a therapeutic effect.

[0003] In existing technologies, many improvements have been made to moxibustion patches to achieve better targeting and purer drug action on the human body. A common improvement is the addition of medicinal essential oils. There are various methods for adding these essential oils. For example, Chinese Patent 201520989692.7 discloses a moxibustion patch with a sealed essential oil bag between the heating layer and the solid drug layer. Before use, the sealed bag is removed, opened, and the essential oil is mixed with the drug in the medicine pack before being pasted on. Alternatively, the sealed bag can be opened to release the essential oil into the medicine pack. However, this structure of moxibustion patch has several drawbacks. First, the process of adding the essential oil to the medicine pack is complex and uncontrollable, easily leading to uncontrolled flow of the essential oil, causing surrounding pollution and waste. Second, using the patch directly after mixing the essential oil with the medicine pack does not achieve the desired effect; it is no different from directly adding the essential oil powder or even the essential oil itself to the medicine pack, and the efficacy is not significantly improved. Meanwhile, there are various improved structures, such as using an external container to add essential oil to the medicine pack before sticking the moxibustion patch to the human body, which is extremely complicated to use; adding an essential oil layer between the heating layer and the medicine layer (using a carrier with adsorption function such as adsorbent essential oil), removing the isolation layer, sticking it on, and starting to heat it to act on the human body, but this structure cannot control the essential oil during use, causing it to spread everywhere; at the same time, none of these structures can handle the problem of essential oil use well, and all of them have the technical problems existing in the aforementioned patent documents, that is, there is no significant difference from direct mixing, packaging, and use, it is just adding the effective ingredients of the medicine.

[0004] Therefore, it is necessary to improve existing moxibustion patches, change the traditional approach of directly mixing essential oils into the medicine pack, improve the utilization rate of the medicine, and enhance the therapeutic effect. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a medicated patch that delivers medication to the human body in a stepwise manner, changing the traditional approach of directly mixing essential oils into the medicated patch, improving the utilization rate of the medication, and enhancing the therapeutic effect.

[0006] The medicated patch of the present invention, which delivers drugs to the human body in a stepwise manner, includes, from the outside in, a back layer, a heating layer, and a solid drug layer, wherein the solid drug layer contains a solid drug A; it also includes a liquid cavity containing a liquid drug B; when in use, after the moxibustion patch is applied to the human body for a set time, the liquid cavity can be opened and the liquid drug B flows into the solid drug layer.

[0007] Furthermore, the liquid drug B flows into the solid drug layer at a location above and behind the solid drug layer.

[0008] Furthermore, the liquid medicine chamber has an operable openable operating end, which is located on the outside of the moxibustion patch.

[0009] Furthermore, a thermally conductive and water-impermeable insulating layer is provided between the heating layer and the solid drug layer.

[0010] Furthermore, the heating layer forms a local depression at a position corresponding to the drug cavity to partially accommodate the drug cavity, and the isolation layer is bonded and fixed to the heating layer at least at the local depression.

[0011] Furthermore, the liquid medicine cavity is located within the solid medicine layer and is bonded and fixed, and the solid medicine layer deforms at local depressions and is bonded and fixed to the local depressions.

[0012] Furthermore, the liquid medicine chamber includes an outer tube and an inner tube. The inner tube is rotatably fitted inside the outer tube, and the tube walls form a closed contact. The liquid medicine B is contained in the inner tube. The outer tube has a downward liquid medicine outlet, and the inner tube has a liquid medicine communication port. The liquid medicine communication port and the liquid medicine outlet are offset in the circumferential direction.

[0013] Furthermore, the first end of the outer tube is located inside the solid drug layer, and the second end extends out of the solid drug layer and the extended part is bonded and sealed to the solid drug layer. The first end of the inner tube is closed and extends out of the first end of the outer tube to form an annular boss that is tightly attached to the first end of the outer tube. The second end extends out of the outer tube to form the operating end. The operating end closes the second end of the inner tube and extends out of the back layer and is exposed.

[0014] Furthermore, both the inner and outer tubes are made of a plastic material with a certain degree of elasticity.

[0015] Furthermore, the liquid medicine chamber is a strip-shaped plastic bag, and a thin strip is formed at the bottom of the strip-shaped plastic bag. A pull line is fixedly connected to the thin strip, and the pull line extends out of the solid medicine layer and the back layer.

[0016] The beneficial effects of this invention are as follows: The medicated patch of this invention, which delivers medication to the human body in a tiered manner, applies solid medication A and liquid medication B to the body in stages according to the required treatment process during use. That is, solid medication A, under the action of heating, provides initial treatment for the relevant disease, while liquid medication B is added progressively after a set time. This not only meets the needs of tiered treatment and has a therapeutic effect, but also allows the remaining efficacy of solid medication B to continue to act on the affected area, improving the utilization rate of the medication and making the treatment more targeted. This changes the traditional mindset of those skilled in the art regarding moxibustion patches being used only once and having a single therapeutic effect, making it possible to use medication intermittently as needed for treatment, thereby improving efficacy and laying the foundation for ensuring the final therapeutic effect.

[0026] like Figures 1 to 5As shown: This embodiment of the drug patch that applies medication to the human body in stages includes, from the outside in, a back layer 1, a heating layer 2, and a solid drug layer 3, wherein the solid drug layer 3 contains a solid drug A; it also includes a liquid cavity 4 that seals a liquid drug B; during use, after the moxibustion patch is applied to the human body for a set time, the liquid cavity 4 can be opened to allow the liquid drug B to flow into the solid drug layer; in the basic structure of the moxibustion patch, the back layer is the outermost layer, and it is generally provided with an adhesive backing for bonding the heating layer and for bonding to the human body during use; the heating layer refers to a self-heating layer, which reacts with air to generate self-heat; the solid drug layer is the drug pack, which generally contains a mixture of drug powders with targeted therapeutic effects, and the side in contact with the human body is also covered with a breathable and liquid-permeable non-woven fabric layer 5. The above are all existing moxibustion patch structures, and will not be described in detail here;

[0027] In this embodiment, the solid drug layer typically has a water-permeable and breathable outer packaging and an inner solid drug A. Solid drug A usually has a powder or fine granular structure with targeted therapeutic effects. Liquid drug B is usually used in sequence with solid drug A, and the stepwise action on the human body has a better therapeutic effect. Solid drug A and liquid drug B are not limited to traditional Chinese medicine ingredients. Solid drug A can be a Western medicine ointment or even a mixture of Western medicine and traditional Chinese medicine ingredients. Liquid drug B can also be traditional Chinese medicine (such as essential oil), transdermal liquid Western medicine, or a mixture. Targeted medication can be selected. During use, not only is the stepwise action used to improve the effect, but the properties of the liquid also carry the effective ingredients of solid drug A, improving the utilization efficiency of the drug.

[0028] For example, for rheumatoid arthritis, existing topical medications typically include moxibustion patches, corresponding Western medicine ointments, and topical plasters. If used in this invention, solid drug A can first incorporate ingredients that promote blood circulation, remove blood stasis, and provide initial anti-inflammatory effects. After half an hour or more (the moxibustion patch should specify the interval between doses for different diseases), liquid drug B is introduced. Utilizing the initial effects of solid drug A, liquid drug B acts on the affected area more quickly and effectively, providing deeper treatment on the basis of initial anti-inflammatory effects, thereby enhancing efficacy and improving treatment results. Since this invention does not discuss clinical drug interactions, but only provides a moxibustion patch structure that allows for a certain interval between drug interactions and allows for simultaneous use but with better results from sequential use, drug interactions and the choice of drugs for treatment are not discussed in this invention.

[0029] In this embodiment, there are various ways to manipulate the liquid drug B into the solid drug layer, such as the existing technology of popping beads (but they are difficult to operate due to their large quantity), plastic bags containing liquid drugs (which have weak points that can be broken by squeezing, but there is a risk of breakage during storage and transportation), etc., which will not be elaborated here.

[0030] In this embodiment, the liquid drug B flows into the solid drug layer 3 at the upper rear of the solid drug layer 3. That is, this moxibustion patch has a directional requirement when used. The actual product will indicate the specific directional location when used, which will not be repeated here. "Upper rear" refers to the upper part closer to the heating layer 2. When using, the liquid drug B is controlled to flow down from the top, so that it can enter the solid drug A more quickly and completely, thus realizing the full utilization of the liquid drug.

[0031] In this embodiment, the liquid medicine chamber 4 has an operable openable operating end 4022, which is located outside the moxibustion patch; the operating end located outside can be operated after the moxibustion patch is pasted, thereby realizing the tiered use of the medicine.

[0032] In this embodiment, a thermally conductive and water-impermeable isolation layer 6 is provided between the heating layer 2 and the solid drug layer 3. The isolation layer 6 is provided to prevent liquid drug B from flowing into the heating layer, and aluminum foil can be used to achieve this function.

[0033] In this embodiment, the heating layer 2 forms a partial depression at the position corresponding to the medicine cavity 4 to partially accommodate the medicine cavity, and the isolation layer 6 is bonded and fixed to the heating layer 2 at least at the partial depression; the partial depression does not require a specific structural setting, since the self-heating material in the heating layer is in powder form, so the partial depression can be formed naturally; of course, a depression structure with relative hardness can also be set at this position, such as plastic or metal sheet formed and pasted at this position, which will not be elaborated here.

[0034] In this embodiment, the liquid medicine cavity 4 is located within the solid drug layer 3 and is bonded and fixed. The solid drug layer 3 deforms at local depressions and is bonded and fixed to the local depressions; for example... Figure 2 As shown, the liquid medicine cavity 4 is bonded to the inside of the packaging of the solid medicine layer 3, and the structure is fixed and easy to operate.

[0035] In this embodiment, the liquid medicine chamber 4 is a sleeve-type liquid medicine chamber, including an outer tube 401 and an inner tube 402. The inner tube 402 is rotatably fitted inside the outer tube 401, and the tube walls form a closed contact. The liquid medicine B is contained in the inner tube. The sealed contact of the tube walls refers to the contact between the inner wall of the outer tube and the outer wall of the inner tube to prevent the liquid medicine from flowing out. This can be achieved by using a material with a certain degree of elasticity. The outer tube 401 has a downward liquid medicine outlet 4011, and the inner tube 402 has a liquid medicine connecting port 4021. The liquid medicine connecting port 4021 and the liquid medicine outlet 4011 are offset in the circumferential direction. Figure 3 , Figure 4 and Figure 6As shown, due to the combination of the staggered liquid connection port 4021 and liquid outlet 4011 with the closed tube wall, when not in use, liquid medicine B is sealed in the inner tube 402. When it is necessary to release the solid liquid, rotate the inner tube 402 so that the liquid connection port 4021 faces downward and is opposite to the liquid outlet 4011, and then the liquid medicine B flows out downward. The operation is simple and convenient.

[0036] In this embodiment, the length of the outer tube and the inner tube should basically cover the entire solid drug layer 3. If a large amount of liquid drug B is required, two liquid chambers 4 can be set. Since the moxibustion patch needs to be thick, increasing the diameter is not suitable, and a large diameter is not conducive to sealing. The liquid connection port 4021 and the liquid outlet 4011 are preferably strip-shaped, which is conducive to the full outflow of liquid. Of course, a densely arranged circular hole can also achieve the purpose of the invention and ensure strength.

[0037] In this embodiment, the first end of the outer tube 401 is located inside the solid drug layer 3, such as... Figure 1 and Figure 3 As shown, the second end of the outer tube 401 extends out of the solid drug layer 3, and the extended portion is bonded and sealed to the packaging of the solid drug layer 3. The bonding and sealing method is existing technology and will not be described in detail here. The first end of the inner tube 402 is closed, and the extension of the first end of the outer tube forms an annular protrusion 4023 that is tightly attached to the first end of the outer tube. Figure 1 As shown, this structure can prevent the inner tube 402 from detaching from the second end of the outer tube 401. The second end of the inner tube 402 extends out of the outer tube to form the operating end 4022. The operating end 4022 closes the second end of the inner tube 402, generally using an integrally formed closed structure. The operating end 4022 extends out of the back layer 1 and is exposed. A hole needs to be opened on the back layer for the operating end 4022 to pass through. After the moxibustion patch is pasted on the human body, the operating end should be exposed out of the back layer 1 for easy operation. Of course, in order to prevent the inner tube from detaching from the first end of the outer tube, after the inner tube 402 is injected with medicine and installed in place, an elastic retaining ring 4024 is set on the operating end (of course, the operating end should have an annular groove that cooperates with the elastic retaining ring), which cooperates with the annular boss 4023 to form an axial restriction on the inner tube. This will not be elaborated further here.

[0038] In this embodiment, both the inner tube 402 and the outer tube 401 are made of plastic material with a certain degree of elasticity. They are usually made of polystyrene or modified polystyrene, which have good flexibility and a certain degree of elasticity and strong adaptability to deformation. Further details will not be provided here.

[0039] During assembly, there should be an oil film (medicinal essential oil or petroleum jelly is sufficient) between the outer tube 401 and the inner tube 402 to ensure flexible rotation, which will not be elaborated here.

[0040] The liquid medicine chamber of the present invention can also have the following structure: the liquid medicine chamber is a strip-shaped plastic bag 4a, the lower part of the strip-shaped plastic bag 4a forms a strip-shaped weak band 4a01, the strip-shaped weak band 4a01 is fixedly connected to a pull line 4a02, the pull line 4a02 extends out of the solid medicine layer 3 and extends out of the back layer 1; this structure has good manufacturability and is easy to produce; the structure with the strip-shaped weak band on the plastic bag is an existing pull-out structure, which will not be described in detail here; however, this structure is easily damaged when subjected to large external pressure during storage or transportation. Compared with the aforementioned embodiments, it has weaknesses and is not a preferred structure of the present invention.

[0041] The medicated patch of the present invention refers to a patch applied externally for treatment and relief of patients, including common forms such as moxibustion patches, which will not be described in detail here.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
