Description
Technical Field
The utility model belongs to the technical field of the external patch, concretely relates to waterproof ventilative analgesic patch.
Background
The diclofenac sodium is a novel non-steroidal anti-inflammatory analgesic which is widely applied clinically, has good antipyretic analgesic effect, and can be clinically used for treating rheumatoid arthritis, ankylosing arthritis, lupus erythematosus, lumbago and backache, scapulohumeral periarthritis, pain caused after various operations, fever caused by various reasons and other diseases.
At present, when people use the analgesic patch, the analgesic patch is attached to the surface of skin, and the drug is absorbed by the skin and enters the blood circulation of human body to achieve effective blood concentration, and the effects of relieving pain, diminishing inflammation and the like are achieved. In order to enable the medicine to be fully absorbed into the blood of a human body, people need to continuously attach the analgesic patch for a long time, the patch can lose viscosity and fall off when meeting water and lose curative effect when meeting water in the process, the analgesic patch is attached to the skin for a long time, skin sweat secretion can cause whitening of the skin, bacteria can be easily bred, skin infection risks are increased, and therefore the patch also needs to have good air permeability.
Disclosure of Invention
The utility model provides a not enough to prior art, the utility model provides a waterproof ventilative subsides of alleviating pain agent, it has superstrong waterproof nature, and the gas permeability not only can prevent to store up medicine glue film and meet water and lose viscidity and drop and skin and meet water whitening infection, can also realize effects such as the antiphlogistic that relieves pain.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
a waterproof breathable analgesic patch characterized by: the patch comprises a bottom paper layer, a medicine storage adhesive layer, a backing material layer and a waterproof layer from top to bottom;
the base paper layer is release paper;
the medicine storage glue layer contains diclofenac sodium pain relieving functional components;
the backing material layer is elastic cloth or non-woven fabric;
the waterproof layer is a PTFE film or a polyurethane film and is bonded with the backing material layer and the bottom paper layer through an adhesive.
Further, the release paper is one with a single-side PE film coated with silicone oil, the silicone coated surface is directly attached to the medicine storage adhesive layer and the waterproof layer, and the size of the release paper is consistent with that of the waterproof layer.
Further, the main component in the medicine storage adhesive layer is medical water-based acrylic pressure-sensitive adhesive, wherein the mass percentage content of the effective component sodium dichlorophenolate is 10-20%, and the thickness of the medicine storage adhesive layer is 0.02-0.04 mm.
Furthermore, the elastic cloth or the non-woven fabric has high air permeability and high softness, so that skin bacteria can be effectively prevented from breeding and the elastic cloth or the non-woven fabric can be better attached to the skin.
Further, the thickness of the waterproof layer is 0.015-0.05 mm.
Furthermore, the PTFE film or the polyurethane film is uniformly distributed with a plurality of fine vent holes, and the porosity is more than or equal to 60 percent.
Further, the adhesive is a waterproof acrylic pressure-sensitive adhesive.
Furthermore, the average width of waterproof layer 2 ~ 4cm than backing material layer and medicine storage glue film width, this structural design can effectually prevent that water from sticking to agent edge infiltration entering in the use of the emplastrum that relieves pain to effectively avoid medicine storage glue film to lose the viscidity when meeting water and drop and skin to meet water reinforcing infection risk.
The utility model relates to a waterproof ventilative pain-relieving patch's beneficial effect is: the medicine storage adhesive layer adopts medical water-based acrylic pressure-sensitive adhesive, has mild irritation to skin, contains 10-20% of diclofenac sodium in percentage by mass as an effective component, has high medicine loading rate and good stability, and can effectively achieve the treatment effects of relieving pain and diminishing inflammation for a long time. The waterproof layer adopts a PTFE film or a polyurethane film, the waterproof layer has excellent waterproof effect, a plurality of fine vent holes are uniformly distributed on the film through special punching treatment, the film has good air permeability, and the waterproof acrylic pressure-sensitive adhesive is bonded with the backing material layer, so that the whole analgesic patch has excellent waterproof function and is more convenient to use in daily life.
Drawings
Fig. 1 is a schematic structural view of the waterproof breathable pain-relieving patch of the utility model.
Wherein, the adhesive comprises 1-a bottom paper layer, 2-a medicine storage adhesive layer, 3-a backing material layer, 4-an adhesive and 5-a waterproof layer.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
example (b): the patch comprises a bottom paper layer 1, a medicine storage adhesive layer 2, a backing material layer 3 and a waterproof layer 5 from top to bottom; the backing material layer 3 is non-woven fabric, and the thickness is 0.1 mm; the waterproof layer 5 is a polyurethane film, is bonded with the backing material layer 3 and the bottom paper layer 1 through an adhesive 4, and has the porosity of more than or equal to 60 percent and the thickness of 0.03 mm; the thickness of the 2-medicine storage glue layer is 0.03 mm.
In this embodiment, the average width of waterproof layer 5 is 3cm wider than backing material layer 3 and 2 medicine storage glue layers, and every side distance 5-waterproof layer limit of backing material layer 3 and medicine storage glue layer 2 is about 1.5cm promptly, and this structural design can effectually prevent that water from permeating into from waterproof ventilative pain-relieving patch edge in the use to avoid medicine storage glue layer 2 to meet the water and lose viscidity and drop and skin meets water and strengthen the infection risk.
In this embodiment, when the waterproof air-permeable analgesic patch is used, the base paper layer 1 covering the edges of the drug storage adhesive layer 2 and the waterproof layer 5 is peeled off, the waterproof air-permeable analgesic patch is applied to the skin of the affected part by holding the waterproof air-permeable analgesic patch with a hand, and the waterproof air-permeable analgesic patch is lightly stroked to be applied to the skin of the affected part smoothly and firmly, and the application is completed.
