Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, an external patch for improving air permeability, comfort and extensibility is composed of a backing film 1, a paste layer 2 and a paste surface protective film 3, wherein the backing film 1 is attached with the paste layer 2, and the paste surface protective film 3 covers the paste layer 2 and the backing film 1. The backing film 1 is a translucent polyester film or a non-woven fabric; the backing film 1 comprises a micro pinhole or a plurality of laser cutting holes 4 processed by laser equipment; the backing film 1 is processed into a plurality of rows of notch combinations by laser equipment, the notch combinations are in a rhombus shape with non-intersected diagonals and non-connected four sides, and each row of notch combination is composed of a plurality of notches 5; all of the slits 5 adjacent to the periphery of the backing film 1 do not communicate with the periphery of the backing film 1. The plaster layer 2 is a medicine-containing layer containing raw material medicine, and the plaster surface protective film 3 is a colorless transparent polypropylene film or glassine paper. All the cuts 5 on the backing film 1 are cut through, and the paste layer 2 and the paste surface protective film 3 have no cuts 5.

The plaster surface protective film 3 is made of release paper, plastic or metal materials, and specifically, the plaster surface protective film 3 is a colorless transparent polypropylene film or glassine paper. When the plaster surface protective film is removed, the peeling of the raw material drug storage and the backing film is not caused. The plaster surface protective film of the external patch is impermeable to raw material drugs and usually impermeable to water.

The aperture of a plurality of micro pinholes processed by the micro pinhole equipment is 0.05-0.3mm, and the distance between any two adjacent micro pinholes is 3-9 mm.

When backing film 1 is a translucent polyester film and the release film is a colorless transparent polypropylene film, the entire external patch is translucent and the skin surface condition can be observed at any time.

The laser cutting holes or micro pinholes of the backing film can increase the air permeability of the external patch during application; a plurality of mutually-unconnected cuts are processed on the backing film by laser equipment, the backing film and the paste layer are pasted on the surface of skin, such as the skin is pasted on joint parts of neck, knee, elbow, neck, shoulder blade and the like, all cuts are pulled open along with the movement of the joint parts and the stretching of the skin, because the cuts in two adjacent rows of cutting combinations are arranged in a staggered and staggered way, the pulled backing film forms a net structure, the backing film can stretch, the phenomena that the backing film is tilted, the pasting is not firm and the movement of the pasting part is influenced are avoided, and therefore the air permeability and the pasting comfort of the external patch are enhanced.

The minimum distance 7 of the periphery of the backing film 1 without the notch 5 is 2-25 mm; the length 6 of the incision 5 is 4-10 mm.

The notches 5 in two adjacent rows of notch combinations are arranged in a staggered span manner, and the distance 8 between the center points of the adjacent rhombic notch combinations in the same row is 10-22 mm; the distance 9 between two adjacent notches 5 of two adjacent rows of notch combinations is 2-10 mm; the slits 5 are linear.

The utility model discloses external patch pastes and applies in the skin surface, especially paste and apply in joint position, if paste and apply in knee, elbow, neck, when the shoulder blade portion etc. produces a large amount of activity positions, when moving, all incisions on the backing film can be along with the knee, elbow, neck, the flexible quilt of joint position skin such as shoulder blade portion is pulled open, because the incision dislocation in two adjacent lines of incision combinations is striden well-setting, the backing film that the incision was pulled open becomes network structure, the backing film becomes can stretch out and draw back, avoided the backing film to appear pasting insecure, the phenomenon easily drops, and simultaneously, the laser who processes on the netted space that the incision that pulls open formed and the backing film cuts the hole, the gas permeability of external patch has been strengthened.
