[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides an external patch structure suitable for the neck, shoulder, waist and legs, comprising a base patch 1 and a medicine patch 2, a surface adhesive layer 3 is fixedly arranged on the bottom surface of the base patch 1, a medicine hole 4 is fixedly opened inside the base patch 1, and an expansion spacer ring 5 is arranged on the outer edge of the medicine hole 4 and the outer edge of the base patch 1;

[0023] The expansion ring 5 is composed of a polymer composite material and bubble particles. The expansion ring 5 expands when exposed to water, and the polymer composite material is rubber.

[0024] The double expansion spacer ring 5 is provided to improve the waterproofness of the outer side of the base sticker 1 on the one hand, and to prevent the drug from overflowing the area of ​​the drug hole 4 on the other hand;

[0025] The base patch 1 is bonded and matched with the medicine patch 2;

[0026] The top surface of the base patch 1 is fixedly provided with a Velcro hook surface 13, and the bottom surface of the medicine patch 2 is fixedly provided with a Velcro fur surface 14 bonded with the Velcro hook surface 13, and both the Velcro hook surface 13 and the Velcro fur surface 14 are annular structures.

[0027] A drug storage cartridge 6 is threadedly mounted on the patch 2, and a precipitation net 7 is mounted at the bottom of the drug storage cartridge 6, wherein the precipitation net 7 is a mesh.

[0028] The inner wall of the drug storage cartridge 6 is threadedly connected with a drug pressing cartridge 8, and a pressure capsule 9 is installed on the bottom surface of the drug pressing cartridge 8. The pressure capsule 9 is made of silicone material, and an anti-stick coating is fixedly arranged on the bottom surface of the pressure capsule 9.

[0029] The space between the pressure bag 9 and the medicine storage cylinder 6 is filled with ointment for treating the neck, shoulders, waist and legs;

[0030] By setting the anti-stick coating, the adhesion rate of the ointment on the bottom surface of the pressure capsule 9 is effectively reduced;

[0031] A cavity connected to the pressure capsule 9 is fixedly opened inside the pressure cartridge 8, and the interior of the cavity is filled with a self-heating layer 10, which is a mixture of iron powder, vermiculite, activated carbon, inorganic salt, resin and water;

[0032] A drum pressure chamber 11 communicating with the cavity is fixedly provided inside the medicine pressing cartridge 8 , and a drum pressure plug 12 is threadedly mounted on the inner wall of the drum pressure chamber 11 .

[0033] The drug storage cartridge 6 , the drug pressing cartridge 8 and the drum pressure plug 12 are all made of silicone material, and the outside of the drug storage cartridge 6 and the drug pressing cartridge 8 and the top of the drum pressure plug 12 are all fixedly provided with a driving part.

[0034] By setting the driving part, the drug storage cylinder 6, the drug pressing cylinder 8 and the drum pressing plug 12 are effectively driven;

[0035] A group of air permeable areas 15 are arranged inside the medicine patch 2 and at positions corresponding to the periphery of the medicine storage cylinder 6. The arrangement of the air permeable areas 15 effectively improves the comfort level of the patient when using the medicine patch 2.

[0036] The working principle and use process of the utility model are as follows: when in use, the medicine patch 2 and the base patch 1 are bonded as one, and the base patch 1 is fixed to the treatment part such as the neck, shoulder, waist or leg through the surface adhesive layer 3. When applying medicine, the bottom surface of the medicine storage cylinder 6 is pressed and fitted with the part to be applied. After the medicine storage cylinder 6 is arranged, a sufficient amount of ointment is filled into the interior of the medicine storage cylinder 6. After the ointment is filled, the pressure capsule 9 is driven to fully press the ointment, and finally, the ointment is fully fitted with the part to be treated of the human body, thereby improving the therapeutic effect of the ointment. During ointment treatment, the ointment is kept in a hot-melt state through the setting of the self-heating layer 10, thereby effectively avoiding the ointment from condensing and increasing the volatilization speed of the ointment efficacy. When it is necessary to change the medicine or observe the treatment part, the medicine patch 2 is torn off the base patch 1, and the ointment after the efficacy is volatilized can be completely taken out by replacing the medicine storage cylinder 6. After the medicine storage cylinder 6 is replaced, the ointment is added again, and then a quick medicine change is achieved.
