Abstract
The utility model disclose a water-proof patch with a structural layer capable of warning in the presence of water, and is used for the water-proof protection of skin wounds, umbilical regions of newborns, and ears of infants and children. The water-proof patch sequentially comprises a thin-film layer, a medical adhesive layer, an alarming layer changing colors in the presence of water, a functional water-absorption heating pad, a wound adhesion-preventing layer and a release paper layer, wherein the wound adhesion-preventing layer can directly contact with the wound without causing the adhesion between the wound and the water-proof patch; and the alarming layer changing colors in the presence of water can have color changes after contacting with tap water at different temperatures. The utility model has the advantages of good water-proof performance, direct contact with wound, no generation of pain or bleeding, and more comfortable and safer application, and reminds the user of water leakage in time, thereby enhancing the practicability and the safety.
Description
Technical field
This utility model belongs to a kind of medical care products, is used for applying ointment or plaster of skin wound, neonatal umbilicus, young baby and child's ear waterproofing protection, particularly a kind of have meet the waterproof paster that the water policeman shows structure sheaf.
Background technology
In daily life, people often paddle because of the wound before skin injury that causes because of carelessness and the neonatal umbilicus healing, neonate is had a bath, problem such as ear water inlet all can be run into unavoidably when young baby and child swimming were played in the water, and very easily caused infection in various degree.Therefore according to above-mentioned situation and from protecting healthy angle of future generation, must carry out waterproofing protection.
Chinese patent CN2136649 (waterproof wound film) discloses a kind of waterproof wound film, is base material with plastic sheeting such as polyethylene film, and coating medical glue sticks non-woven fabrics, covers separate paper more thereon; During use, open separate paper, non-woven fabrics is aimed at wound site, and adhesive is affixed on skin, and whole waterproof wound film is affixed on wound.This waterproof wound film has all adopted chance water to change not very significantly material, when consumer causes wound or ear water inlet because of improper use, there have been the risk that infects in wound and tympanum, and this moment, disinfection more in time can't effectively be judged by consumer.This has just increased the risk of consumer's wound infection greatly.Moreover the non-woven fabrics on this class waterproof wound film directly contacts wound, when after the use waterproof wound film being torn, because contacting of non-woven fabrics and wound surface easily causes pain, even occur forming a scab to tear simultaneously falling to causing wound pain, hemorrhage, the situation that wound healing postpones.Above-mentioned this waterproof wound film is difficult to satisfy current consumer demand.
Existing in the market bandage product is also all remaining further improvement aspect comfort and the safety.
Summary of the invention
Task of the present utility model provides a kind of waterproof paster that can overcome above-mentioned defective, waterproof and breathable, have chance water color changing alarm function, and this waterproof paster water resistance is good, is with functional adsorptive pads, uses more comfortable, safety; Have the wound anti simultaneously and use position water inlet color changing alarm function.
The waterproof paster that the water policeman shows structure sheaf is met in having that this utility model provides, comprise thin layer, medical adhesive dressing layer and off-style paper layer successively, medical adhesive is coated on the thin layer, form the medical adhesive dressing layer, it is characterized in that: the middle part between medical adhesive dressing layer and off-style paper layer, set gradually and meet water color changing alarm layer, functional adsorptive pads and wound antiblocking layers, meet water color changing alarm layer and stick on the thin layer through the medical adhesive layer, off-style paper layer covers on wound antiblocking layers and the medical adhesive dressing layer.
Described chance water color changing alarm layer, functional suction heat pad and wound antiblocking layers are a monolithic construction, are arranged at the waterproof paster center.
Described waterproof paster can be that circle, square, rectangle, ellipse or shape of ears are abnormally-structured.
Described wound antiblocking layers adopts a kind of in the antiseized networking of PE, chitosan film, hyaluronate sodium film, carboxymethyl cellulose film, oxidized cellulose film, the polylactic acid membrane, perhaps several compound formations, and its thickness is 0.001～0.5mm.
Described chance water color changing alarm layer is a kind of flexible matrix material that has adsorbed developer, developer by the inorganic salt of pH indicator, starch indicator, the variable color of chance water, meet that in the printing ink of water variable color one or more are compound to be constituted; The flexible matrix material can be a paper, or cotton, or sponge, or non-woven fabrics, or polymeric membrane, and its thickness is 0.01～1.5mm.
Described thin layer constitutes by among PA, PE, PU, PP, PVC, the TPU one or more are compound, has characteristics such as ventilative, waterproof, fungi-proofing, softness; Described thin layer is an one-way membrane, and the perspiration of human body can infiltrate from this layer, keeps skin dry and comfortable, avoids skin aquation to occur because of long-time the stickup.
Described adhesive layer is made of medical adhesive, and medical adhesive and contact skin are pasted firmly, tear easily, is difficult for producing skin allergy.
This utility model waterproof paster (film), the wound antiblocking layers can directly contact wound, but can not cause the adhesion that waterproof wound pastes, and when tearing waterproof paster after the use, can the wound that scab not damaged; Meet water color changing alarm layer after the normal different temperatures tap water of contact, change in color can take place, in time remind consumer by change in color, need the position of protection, remind consumer in time to adopt remedial measures because paddle and the waterproof paster improper use has caused infiltration; Off-style paper layer can be peeled off, and prevents that in production, storage, transportation thin layer from curling, and keeps the cleaning of thin layer, medical adhesive dressing layer and wound antiblocking layers, and the viscosity that keeps adhesive layer.
