Problems solved by technology

Take the most well-known Japanese Kobayashi Liquid Band-Aid as an example. As a film-forming material, nitrocellulose has good waterproof and air permeability, but has disadvantages such as pungent smell and no obvious antibacterial effect; domestic liquid Band-Aid related patents also have various deficiencies: Using water as a solvent, the film forming speed is slow and inconvenient to use (201410616668.9, 201510484327.5); Contains ether, has a bad smell, and is prone to safe

Abstract

The invention provides a multifunctional liquid band-aid and a preparation method thereof, and relates to the field of medical treatment and public health. The multifunctional liquid band-aid comprises the following raw materials in parts by weight: 5-15 parts of a film-forming material, 0.1-4 parts of a local anesthetic, 0.5-1.5 parts of an antioxidant, 2-15 parts of a plasticizer, 1-20 parts ofa skin emollient, 0.1-1 part of an aromatic agent and 20-85 parts of a fast-drying solvent. The invention has the following characteristics: the prepared liquid band-aid is adhesive, can form a film at the wound quickly, and has excellent waterproofness; the local anesthetic lidocaine and the antioxidant vitamin E play a synergistic role to relieve wound pain, effectively inhibit bacteria and accelerate wound healing; the liquid band-aid is applicable to various complex-shaped wounds and has a certain toughness and permeability; the formed film is transparent and regular so that the wound healing conditions can be observed at any time; and the liquid band-aid provided by the invention has high safety, no toxicity and no obvious skin irritation.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to a liquid band-aid, in particular to a multifunctional liquid band-aid and a preparation method thereof. Background technique [0002] Skin injuries are very common in life, and band-aids are often used for wound treatment. However, ordinary band-aids are not waterproof and breathable, and long-term coverage may cause wound ulceration; the shape is fixed, and it is not easy to stick to narrow places and joints, so it cannot be applied to wounds in various parts; when the band-aid is torn off, it may cause secondary damage to the wound and pain. Therefore, an ideal Band-Aid should have the advantages of waterproof, breathable, pain relief, antibacterial, stretchable, tensile, easy to paste, does not affect joint movement, does not need to be removed, and has a good smell. In recent years, there have been many studies on liquid band-aids. Before use, they are in liquid form. After bein...
