Description
Technical Field
The utility model relates to an acupuncture point pastes technical field, concretely relates to waterproof three of PU membrane are bent over.
Background
The Sanfu plaster, originated from the 'Tian moxibustion' of the traditional Chinese medicine, is an ancient external treatment method of the traditional Chinese medicine, is a summer treatment method for preventing and treating diseases by pasting a traditional Chinese medicine ointment on acupuncture points, and has the effect of being similar to the effect of treating diseases by using an oral decoction. Three volt days per year: on the first, middle and last day, the specific acupoints are selected and the Chinese medicinal ointment is applied to treat the corresponding diseases, so it is called Sanfu plaster. It can be used for preventing and treating bronchial asthma, chronic bronchitis, chronic cough, chronic rhinitis, chronic pharyngitis, allergic rhinitis, repeated common cold, and osteoarthritis. The method is increasingly accepted by more people due to simple use and remarkable effect.
The operation method of the three-voltage patch comprises preparing Chinese medicinal ointment, cutting the medical adhesive plaster into pieces of required size, uncovering the upper cover film of the adhesive plaster, applying the Chinese medicinal ointment to the center of the adhesive plaster, and applying the adhesive plaster coated with the Chinese medicinal ointment to corresponding acupuncture points of a patient. The Sanfu paste does not have waterproof performance and is poor in air permeability. Some sanfu plasters directly use waterproof materials as rubberized fabric for waterproofing, for example, a PU film is made into rubberized fabric with adhesive on one side and directly contacts with skin. However, the PU film is a plastic film, has poor air permeability, and may cause discomfort to a patient when being in contact with the skin for a long time; meanwhile, the ointment is difficult to fix, and even if the ointment is placed in the leakage-proof ring, the ointment is easy to leak out of the leakage-proof ring if a patient attached with the sanfu patch moves or sweats due to the fact that the ointment is hot in summer, so that the effect of traditional Chinese medicine is affected, clothes of the patient are possibly dirtied, and inconvenience is brought. Therefore, it is necessary to provide a waterproof three-fold patch of PU film to solve the above problems.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned prior art, the utility model aims at providing a waterproof three of PU membrane are bent over. The three-volt patch can effectively prevent water and can prevent ointment from leaking.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a PU film waterproof three-volt patch, which comprises a medicine storage pool, wherein the medicine storage pool is internally provided with ointment; the medicine storage tank is a cylinder with one open end; a limiting belt is arranged around the periphery of the medicine storage pool and connected with the opening end of the medicine storage pool; the limiting belt is a cross-shaped medical plaster or pressure-sensitive adhesive, and the width of the limiting belt is larger than or equal to the diameter of the medicine storage pool; a waterproof layer is arranged above the limiting belt and is a PU film capable of being stuck; the waterproof layer is positioned on the periphery of the medicine storage tank, the waterproof layer is square, and the limiting belt is covered by the waterproof layer; a first release paper bonded with the limiting belt is arranged below the limiting belt; and a second release paper is arranged on the part which is not connected with the limiting belt and below the waterproof layer.
In practical application, the waterproof layer and the limiting layer can be covered by using a layer of release paper due to the fact that the waterproof layer and the limiting layer are thin.
Preferably, the waterproof layer and the limiting belt are both provided with a plurality of air holes; the air holes of the waterproof layer are communicated with the air holes of the limiting belt above the waterproof layer.
Preferably, the waterproof layer is positioned above the medicine storage pool.
Preferably, the waterproof layer is fixed on the top of the medicine storage tank. Because the waterproof layer has viscidity, can take the bonding with the spacing, so the waterproof layer is fixed and can also protect the medicine storage tank at the top of medicine storage tank.
The utility model has the advantages that:
the utility model solves the problem of external seepage of the ointment and ensures that no gap exists between the ointment and the adhesive plaster; but also can improve the waterproof and air permeability of the three-fold patch. And simple structure, during the in-service use, need not first from type paper protection film and second from type paper protection film, can realize its effect with the same from type paper protection film of waterproof layer area. The utility model discloses an increase the enhancement layer and can effectively fix the ointment, can also reduce the area of contact of PU membrane and skin, reduce the discomfort that the PU membrane brought the patient.
