Description

Technical Field

[0001] The invention relates to the technical field of external plasters, in particular to a novel safe external plaster and a preparation method thereof. Background Art

[0002] A kind of Chinese medicine for external use, known as a thin patch in ancient times. It is made by boiling vegetable oil or animal oil with medicine into a gelatinous substance, which is applied to one side of cloth, paper or leather. It can be attached to the affected area for a long time. It is mainly used to treat sores, boils, swelling and pain, etc.

[0003] Plasters work through the skin. Plaster therapy is one of the commonly used external treatment methods in TCM. It follows the principles of TCM syndrome differentiation 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 compound of multiple drugs to exert the good effect of drugs. Since plasters are directly applied to the body surface, and most of the drugs used to make plasters have a strong smell, and then add strong pungent and fragrant meridian-guiding drugs, they penetrate into the skin, pass through the meridians and internal organs, and play a role in regulating qi and blood, unblocking meridians, dispersing cold and dampness, and relieving swelling and pain.

[0004] For example, the plaster base material, external plaster, cold-relieving and analgesic plaster, cold-relieving and analgesic plaster and preparation method thereof with application number 201610805544.4, the external plaster contains an external plaster base material. The cold-relieving and analgesic plaster is mainly made of Cynanchum chinense and an external plaster base material. The cold-relieving and analgesic plaster includes the above-mentioned plaster, a limiting ring and a flexible base layer, the limiting ring and the base layer together form a groove, and the plaster is arranged in the groove. This cold-relieving and analgesic plaster is not easy to overflow. This cold-relieving and analgesic plaster is mainly made of the whole plant of Cynanchum chinense and graphene powder material. The external plaster base material can be used in all external plasters. This base material and plaster can quickly absorb infrared rays and make the plaster warm up, enhancing the efficacy and absorption. This cold-relieving and analgesic plaster has good cold-relieving and analgesic effects, and the preparation method of the cold-relieving and analgesic plaster is also relatively simple, easy to implement and mass-produce, and conducive to promotion. However, the plaster still has certain defects;

[0005] External plasters are generally applied outside the body, and the medicine leaks out. The medicine itself has a medicinal smell. When different medicines are mixed, a pungent smell will be produced. After the plaster is used, there is still a pungent medicinal smell on its surface. Therefore, it is inconvenient to handle the plaster after use. Plasters with strong odor will cause certain pollution to the environment.

[0006] Therefore, we propose a novel safe external plaster and a preparation method thereof, in order to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a new type of safe external plaster and a preparation method thereof, so as to solve the problem raised by the above background technology that the existing external plasters on the market are generally applied outside the body, the medicine leaks out, and the medicine itself has a medicinal smell. After different medicines are mixed, a pungent smell will be produced. After the plaster is used, there is still a pungent medicinal smell on its surface. Therefore, it is inconvenient to handle the plaster after use, and the plaster with a strong odor will cause certain pollution to the environment.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new type of safe external plaster and a preparation method thereof, comprising a non-woven fabric, a plaster machine base and a plaster body, a plaster machine base being installed on the top of the non-woven fabric through a first adhesive layer, and a plaster body being arranged on the top of the plaster machine base, and a PU waterproof film being arranged on the upper surface of the plaster body through a second adhesive layer, separation grooves being provided on the front and back sides of the non-woven fabric, and a cutting groove being provided on the upper surface of the non-woven fabric, a waterproof transparent film being installed on the lower surface of the non-woven fabric through a fixing glue, and air holes being provided on the non-woven fabric.

[0009] Preferably, the second adhesive layer is attached to the lower surface of the PU waterproof film, and the area of ​​the PU waterproof film is equal to the area of ​​the plaster body, and the outer side of the plaster body may be surrounded by a cotton strip.

[0010] By adopting the above technical solution, the PU waterproof film protects the plaster body and prevents the plaster body from overflowing. If the plaster body overflows, the overflowed plaster body can be absorbed by the cotton strip, thereby preventing the plaster body from being wasted, and the plaster body absorbed in the cotton strip can be adhered to the skin surface for use.

[0011] Preferably, the cutting groove runs through the non-woven fabric and the plaster body, and the cutting groove and the separation groove are located on a straight line parallel to the side surface of the non-woven fabric.

[0012] By adopting the above technical scheme, if the area to be applied is relatively small, it can be torn off through the cutting groove position, and then the non-woven fabric and the plaster body can be separated under the action of the separation groove, and a part can be selected for application. If the application area is relatively large, the left side of the non-woven fabric can be directly torn off, and the entire plaster body can be applied, thereby facilitating the separation of the plaster body and avoiding waste of the plaster body.

[0013] Preferably, the waterproof transparent film is designed as an inwardly rolled structure, and the width of the waterproof transparent film is equal to the width of the non-woven fabric. When the waterproof transparent film is separated from the fixing glue, the waterproof transparent film can be opened.

[0014] By adopting the above technical scheme, the waterproof transparent film can serve as a support point for tearing the plaster when it is in the rolled-up state. After the plaster is used up, the waterproof transparent film is pulled out to separate the waterproof transparent film from the fixing glue, and one side of the non-woven fabric-like waterproof transparent film is rolled up, and then the non-woven fabric is wrapped by reversely rolling the waterproof transparent film, so that the waterproof transparent film is rolled up to the position of the fixing glue, and the waterproof transparent film is fixed by the fixing glue, and then the used plaster body can be thrown into the trash can along with the non-woven fabric, which greatly reduces the odor emitted by the plaster body and plays a role in environmental protection.

[0015] Preferably, a plurality of ventilation holes are provided, and the ventilation holes penetrate through the base of the plaster machine.

[0016] By adopting the above technical solution, the overall air permeability of the plaster is improved through the air holes, so as to prevent sweat accumulation when using the plaster, causing the plaster to fall off and causing discomfort to the user.

[0017] Preferably, the preparation method specifically comprises the following steps:

[0018] Step 1: Prepare the ingredients: prepare peach kernel, ephedra, angelica, raw aconite, lindera strychnifolia, angelica dahurica, safflower and lotus leaf, prepare 2 glass bottles, and take fresh vegetable oil 2-3 days in advance and let it stand in a glass bottle, then pour the vegetable oil into another glass bottle;

[0019] Step 2: Mix the prepared peach kernel, ephedra, angelica, raw aconite, lindera strychnifolia, angelica dahurica, safflower and lotus leaf medicinal materials together, and cut the medicinal materials with a knife to reduce the volume of each medicinal material;

[0020] Step 3: Place the cut peach kernel, ephedra, angelica, raw aconite, lindera strychnifolia, angelica dahurica, safflower and lotus leaf in a container, and pour the prepared vegetable oil into the container to cover the herbs, and soak the herbs for about 2-3 days;

[0021] Step 4: Take out the herbs and filter them with a filter. Pour the filtered vegetable oil into the pot. After cooling, wrap the herbs with vegetable oil with cotton yarn, wring out the herbs, squeeze out the oil in the herbs, filter it and set it aside for later use.

[0022] Step 5: Heat the vegetable oil in the pot in step 4 to a high heat and boil it, add the wrung-out herbs, stir and squeeze the herbs for 2 minutes, then use a low heat. After 10 minutes, take out the herbs, pour in the oil in step 4 and continue squeezing, and continue stirring;

[0023] Step 6. When stirring until there is no smoke, add the medicine pill into the pot and continue stirring until it becomes a paste. It can be used after cooling, or it can be put into cold water for rinsing after cooling. Apply the prepared plaster on the base of the plaster machine.

[0024] The above technical solution is used to prepare the plaster body, thereby facilitating the subsequent coating of the plaster body on non-woven fabric for use.

[0025] Preferably, the fresh vegetable oil in the step 1 needs to be left to stand in the glass bottle for about half a day before being poured into another glass bottle. Meanwhile, 50 g each of peach kernel, ephedra, angelica and raw aconite are taken, and 30 g each of lindera strychnifolia, angelica dahurica, safflower and lotus leaf are taken.

[0026] By adopting the above technical solution, impurities generated in the vegetable oil during oil pressing are precipitated by standing, thereby preventing the impurities from being mixed into the subsequently prepared plaster patch and affecting the use effect of the plaster.

[0027] Preferably, in step 2, the medicinal materials are cut into pieces with a width of two fingers and mixed evenly.

[0028] The above technical solution is adopted to facilitate the soaking of medicinal materials, while improving the efficiency of the plant oil soaking into the medicinal materials, reducing the soaking time of the medicinal materials, and improving the preparation efficiency of the plaster.

[0029] Preferably, when applying the plaster in step six, the plaster needs to be evenly applied on the base of the plaster machine, and a cotton strip is wrapped around the outside of the plaster, and the cotton strip can be adhered to the plaster.
