Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a self-heating traditional Chinese medicine acupoint application patch for improving drug permeability. Background Technique

[0002] China is the earliest country to apply herbs to the skin and adopt the local administration method to treat diseases such as wound pain and infection. The application technique was first recorded in the "Prescriptions for Fifty-two Diseases" in the Eastern Han Dynasty. "Apply the fresh thistle mashed on the middle of the wound" when bitten by a poisonous snake. In the Qing Dynasty, the medical expert Wu Shiji published the earliest external treatment monograph in China, "Li Yue Pian Wen", which put forward the theory of treating internal diseases by external treatment. Acupoint application therapy is one of the commonly used external treatment methods in traditional Chinese medicine and is also a characteristic treatment of traditional Chinese medicine. It uses the meridian theory to apply medicine on acupoints and exerts curative effects through the transdermal absorption of drugs and acupoint stimulation. Among them, the transdermal absorption effect of drugs is one of the determinants of curative effects.

[0003] The largest organ of the human body is the skin. Transdermal drug delivery is the third largest drug delivery system after oral administration and injection administration. Acupoint application can avoid the first-pass effect of the liver and the gastrointestinal inactivation effect that may occur in oral administration, and also avoid the problem of too high peak drug concentration caused by intramuscular injection. Compared with oral administration and injection administration, acupoint application can make drugs enter the blood more stably and reduce side effects. The main advantages are as follows: 1. The effective drug concentration is constant. The drug delivered transdermally can be stably and continuously released from the patch to maintain a stable blood drug concentration, keep the blood drug concentration within the effective treatment concentration range, improve curative effects while reducing toxic and side effects. 2. High patient compliance. Patients can take drugs independently. For patients with difficulty in swallowing and elderly patients with poor memory, transdermal drug delivery does not require frequent administration, and the dosing interval is prolonged. 3. High safety. If there is an allergic reaction to the drug, the patch can be removed immediately, greatly reducing the risks brought by oral preparations and injection preparations. 4. Give full play to the characteristics of simplicity, effectiveness, affordability and convenience of traditional Chinese medicine external treatment.

[0004] Although transdermal drug delivery has certain advantages, the skin is also a natural barrier of the human body. Due to the existence of the skin barrier, especially the stratum corneum, most drugs cannot directly penetrate the skin and enter the body. In order to promote transdermal absorption, the currently adopted methods mainly include physical penetration enhancement techniques (electroporation, iontophoresis, magnetic field introduction, ultrasound introduction), chemical penetration enhancers (dimethyl sulfoxide and its derivatives, fatty acids and their esters, amides, alcohols, surfactants), and the application of new carriers (cubic nanocarriers, liposomes, microneedles, etc.).

[0005] However, the above-mentioned penetration enhancement methods also have relatively obvious disadvantages for acupoint application. 1. Physical penetration enhancement technology requires special instruments and cannot achieve long-term wearing of acupoint application with the movement of patients. It is costly and has poor compliance. 2. The application of chemical promoters and new carriers also has the disadvantage of high cost. At present, it is mainly applied to transdermal patches of chemical drugs and monomer drugs, and has not been applied to traditional Chinese medicine acupoint application mainly based on traditional Chinese medicine powder. Summary of the Invention

[0006] In view of the above problems, the utility model provides a self-heating traditional Chinese medicine acupoint application for enhancing the drug penetration rate, which can realize the continuous heating during the traditional Chinese medicine application process to enhance the drug penetration stimulation of the acupoint application, thereby improving the curative effect of the acupoint application therapy.

[0007] To achieve the above object, the utility model provides the following technical solutions:

[0008] A self-heating traditional Chinese medicine acupoint application for enhancing the drug penetration rate, a heating element is arranged on the A side of the main body layer, a bottom film B is arranged at the corresponding position on the B side of the main body layer, a loading ring B is arranged on the bottom film B, and medicinal powder is filled in the loading ring B. The medicinal powder is applied to the skin surface of the human body.

[0009] The main body layer is made of medical non-woven fabric, the bottom film B is made of aluminum foil, and the loading ring B is made of PVC material.

[0010] The heating element includes a loading ring A, self-heating material is filled in the loading ring A, the bottom of the loading ring A is a bottom film A, the other side of the bottom film A is pasted on the main body layer, a breathable layer is covered on the self-heating material, and a surface film wraps and isolates the heating element on the A side of the main body layer.

[0011] The self-heating material is a mixture of iron powder, water, activated carbon, salt, and vermiculite in a certain proportion. After contacting the air, the iron powder begins to oxidize. At the same time, using the strong adsorption of activated carbon, water vapor is stored in the porous structure of the activated carbon. The water vapor liquefies into water droplets, flows out and contacts the air and iron powder, and reacts relatively quickly under the catalytic action of sodium chloride to generate iron hydroxide and release heat. In order to make the temperature last longer, vermiculite is used for heat preservation. The entire heating process can last for about 8 hours, and the highest temperature is about 50 degrees.

[0012] The bottom film A is made of aluminum foil, the loading ring A is made of PVC material, and the breathable layer is made of breathable medical non-woven fabric.

[0013] On the B side of the main body layer, when the loading ring B is in the unused state, a surface isolation film is pasted. The surface isolation film is made of glassine paper and is used to protect the medicinal powder loading structure on the B side.

[0014] The coverage area of the surface film is the glue-coated surface, and a non-glue tearing area is provided at the edge of the glue-coated surface. The surface film is a transparent PE protective film, and the inner side of the protective film is hot melt adhesive, whose function is to isolate the self-heating material from the air and prevent the self-heating material from heating up in advance and causing failure. The setting of the non-glue tearing area facilitates the user to quickly tear off the surface film.

[0015] The B side of the main body layer is the glue-coated surface, and a non-glue tearing area is provided at the edge. The glue-coated surface makes it difficult for the surface isolation film to detach by itself, and the setting of the non-glue tearing area facilitates the user to quickly tear off the surface isolation film.

[0016] The usage method of the present utility model includes the following steps:

[0017] Tear off the surface isolation film on the B side and fill the loading circle with traditional Chinese medicine powder;

[0018] Attach the position of the traditional Chinese medicine powder to the acupoints on the human skin;

[0019] Tear off the surface film on the A side to allow air to contact the self-heating material and generate heat;

[0020] After the application is completed, tear it off and discard it.
