Technical Field

[0001] This utility model belongs to the technical field of heat therapy patches, specifically a self-heating heat therapy patch. Background Technology

[0002] Heating patches, as a common medical aid, are widely used to relieve symptoms such as eye fatigue or soreness, muscle pain, joint discomfort, and lower back pain, and also play an important role in assisting drug treatment. However, existing heating patches have many problems in practical use, limiting their performance and user experience.

[0003] Existing heat therapy patches have a relatively simple drug layer design, typically using a single, integrated drug pack structure, which cannot separate different drugs or different dosages of drugs. This design not only easily leads to drug interference or mixing and ineffectiveness, but also prevents flexible adjustment of drug types or dosages according to specific needs, making it difficult to meet diverse treatment requirements. Furthermore, the heating packs of traditional heat therapy patches are inconvenient to open and use, affecting the user experience. Therefore, there is an urgent need to develop a new type of self-heating heat therapy patch that can solve the above problems. Utility Model Content

[0004] To address the above problems, this utility model provides a self-heating heat pack to solve the technical problems of existing heat packs where the medicine pack inside the medicine layer is an integral structure, and the heat pack is inconvenient to open and use.

[0029] like Figure 1 and Figure 5As shown, in a preferred embodiment, the fixing layer 1 is provided with fixing straps 11 on both sides, with a hook and loop fastener 16 on one side of the fixing strap 11 and a hook and loop fastener 17 on the other side of the fixing strap 11.

[0030] Working principle

[0031] Layered structure and sealing design:

[0032] The fixing layer 1, the heating pack layer 2, and the drug-carrying layer 4 are stacked in sequence and connected by the first adhesive layer 3 and the second adhesive layer 10 to ensure tight bonding and stability between the layers.

[0033] The opening 12 on the heating layer 2 is sealed by the second sealing layer 13. The first peel strip 15 at the opening 12 passes through the through hole 21 of the fixing layer 1 and is glued to the third sealing layer 14. This design makes it easy for the user to open the heating pack 8. When the third sealing layer 14 is opened, the first peel strip 15 is pulled to open the second sealing layer 13 at the opening 12 to facilitate heat dissipation of the heating pack 8. At the same time, it also ensures the sealing of the heating pack 8 before it is used.

[0034] Drug delivery and separation:

[0035] The drug pack 6 within the drug-carrying layer 4 is designed as multiple independent drug-carrying cavities 7, which can be filled with different drugs or drug doses according to different treatment needs. This separation design avoids mutual interference or mixing failure between drugs.

[0036] The shape of the drug-receiving cavity 7 is diverse (square, round, oval or polygonal), and can be optimized according to the properties of the drug and treatment needs.

[0037] Heating mechanism and breathable design:

[0038] The heating pack 8 inside the heating layer 2 generates heat through a chemical reaction. The heat is evenly distributed to the skin surface through the first vent 9 and the second vent 20, ensuring a comfortable and safe hot compress effect.

[0039] The heating layer 2, the first adhesive layer 3, and the drug-carrying layer 4 are provided with second vents 20 to ensure that the heat patch can maintain good breathability during use and reduce skin discomfort and allergic reactions.

[0040] Fixed design:

[0041] The fixing straps 11 on both sides of the fixing layer 1 are respectively provided with hook and loop fasteners 16 and hook and loop fasteners 17. Through the adhesive action of the hook and loop fasteners, the heat therapy patch is firmly fixed to the required part, preventing displacement or falling off, and ensuring the stability of the heat therapy effect.

[0042] Ease of use:

[0043] The second sealing layer 13 and the fourth sealing layer 18 are respectively provided with a first peel strip 15 and a second peel strip 19 on their exterior, which makes it convenient for users to quickly peel them off before use and improves the ease of use.

[0044] Work process

[0045] Preparation before use:

[0046] Tear open the second strip 19 on the fourth sealing layer 18, take out the medicine pack 6 in the medicine-carrying layer 4, place the prepared medicine (liquid, powder or ointment) into the medicine-receiving cavity 7 on the medicine pack 6. The medicine-receiving cavity 7 is made of moisturizing non-woven cotton. Then place the medicine pack 6 in the medicine-carrying layer 4 and secure it firmly with the fourth sealing layer 18.

[0047] While tearing open the third sealing layer 14, the first peeling strip 15 is also pulled, thereby opening the second sealing layer 13 at the opening 12, exposing the opening 12 of the heating pack layer 2, allowing the heating pack 8 to start dissipating heat.

[0048] Fixation of the heat patch:

[0049] After tearing off the first sealing layer 5 on the outside of the drug-carrying layer 4, the outer ring of the drug-carrying layer 4 is adhesive. At this time, apply the adhesive side of the heat patch to the area that needs treatment (waist, eyes, or other areas), and use the fixing strap 11 to firmly fix the heat patch to the body, ensuring that the Velcro fleece side 16 and the Velcro hook side 17 are tightly attached to prevent the heat patch from shifting or falling off.

[0050] Hot compress process:

[0051] The heating pack 8 generates heat through a chemical reaction, which is then evenly distributed to the skin surface through the opening 12, the first vent 9, and the second vent 20. The medication within the drug-loaded layer 4 evaporates or penetrates into the skin through the second vent 20 to exert its therapeutic effect. Throughout use, the vent design ensures the skin surface remains dry, reducing discomfort.

[0052] Post-processing:

[0053] After use, peel off the Velcro on the retaining strap 11 and remove the heat pack. Clean the skin at the application site and properly dispose of the used heat pack.
