Problems solved by technology

This invention uses viscous rubber as a part of the matrix to endow the plaster with viscosity, but the foaming process will cause the plaster to easily remain gasoline, vegetable oil, etc., and the high temperature or the matrix cannot be fully emulsified and swelled to cause oil leakage, and it may be incompatible with the medicament Poor compatibility causes ingredients to separate out and affect drug efficacy or viscosity

Embodiment 1

[0033] Such as figure 1 , 2 As shown, a plaster for treating joint pain includes a peeling layer 1, an ointment layer 2, and a backing layer 4 that are adsorbed in sequence. The four corners of the backing layer 4 are set as rounded corners, which are less prone to floating than right angles and are more securely attached to the skin; the backing layer 4 is made of elastic fiber, which is more elastic; the inner side of the backing layer 4 is divided into the middle and On the periphery, the ointment layer 2 is attached to the middle, and the periphery of the backing layer 4 is provided with an adhesive ring 3, the adhesive ring 3 is close to the ointment layer 2, and the thickness of the adhesive ring 3 and the ointment layer 2 are both 0.1 mm, forming The surface is flat and easy to stick. The peeling layer 1 is attached to the adhesive ring 3 opposite to the backing layer 4, and the adhesive ring 3 and the ointment layer 2 are sandwiched between them for protection. When usi...

Embodiment 2

[0037] Such as image 3 , 4 As shown, a plaster for treating joint pain includes a peeling layer 1, an ointment layer 2, and a backing layer 4 that are adsorbed in sequence. The backing layer 4 is made of elastic fiber, which has great elasticity; the inner side of the backing layer 4 is divided into a middle and a periphery, and the ointment layer 2 is attached to the middle. On the periphery of the backing layer 4, a distance from the ointment layer 2 is provided. The thickness of the adhesive ring 3, the ointment layer 2 is 1 mm, and the upper surface of the adhesive ring 3 gradually declines 0.1 mm from the inside to the outside. The advantage of this setting is to ensure that the ointment layer 2 is always close to the skin and exerts its efficacy. There is a gap between the ointment layer 2 and the adhesive ring 3, which can be adjusted appropriately so that the adhesive ring 3 will not adhere and squeeze to the ointment layer 2, and it can also be used as a ventilation ch...

Embodiment 3

[0040] Such as Figure 5 As shown, the structure of this embodiment differs from the embodiment 1 in that the adhesive ring 3 is different. The adhesive ring 3 becomes a lace wound around the ointment layer 2. Of course, the pattern is not limited to the pattern shown in the figure. Compared with Example 1, the material for the adhesive ring 3 is saved, but by setting it as a multi-line segment and multi-angle pattern, its viscosity can be ensured, and the air permeability can also be increased; moreover, there is a gap between the lace and the outer side of the backing layer 4. The attachment ring 3 is not easy to be coated on the outside of the backing layer 4, and the excess backing layer 4 can protect the adhesive ring 3, and it is not easy to lose its viscosity due to dust on the side.

[0041] The preparation process of the ointment layer 2 is as follows: by weight, first put 30 parts of menthol into 260 parts of 30% water-containing honey mucus and stir evenly to obtain mi...

Abstract

The invention relates to the field of pastes, aims to solve the problem of high requirements on adhesion and air permeability of an adhesive layer when the adhesive layer of a plaster is coated on ointment, and provides a plaster for treating arthralgia. The plaster comprises a stripping layer, an ointment layer and a backing layer which are sequentially adsorbed, the inner side of the backing layer is divided into a middle part and a periphery; wherein the ointment layer is attached to the middle part, a circle of adhesive ring is arranged on the periphery of the backing layer, the adhesive ring has viscosity and can be attached to the skin, the stripping layer is attached to the adhesive ring and opposite to the backing layer to clamp the adhesive ring and the ointment layer between theadhesive ring and the ointment layer to play a role in protection, and during use, the stripping layer is stripped off, and the ointment layer comprises indometacin, dyclonine hydrochloride and menthol. The adhesive layer is arranged on the periphery of the ointment layer by a circle, the adhesive ring and the ointment layer do not interfere with each other, and the adhesion between the adhesive ring and the ointment layer does not need to be considered; the ointment layer is in direct contact with the skin without passing through the adhesive ring, so that the human body can better absorb theointment layer, and the permeability of effective components of the ointment in the adhesive ring does not need to be considered.

Description

Technical field [0001] The present invention relates to the technical field of plasters, in particular to a plaster for treating joint pain. Background technique [0002] Plaster has a long history of application in our country. It is boiled with vegetable oil or animal oil to make a gelatinous substance, and it can be applied on the side of cloth, paper or skin for a long time. The medicine in the plaster is directly applied to the acupoints on the body surface. The medicinal property penetrates the subcutaneous tissue from the surface to the inside through the fur. On the one hand, it produces a relative advantage of the drug concentration locally, and on the other hand, it can directly reach the disease of the visceral disorder and the meridian and qi disorder through the passage of the meridian and exert the functional effect of the drug. So as to exert the greatest systemic pharmacological effect. Traditional injection and oral therapies damage nerves, blood vessels, muscle...
