Technical Field
The present invention relates to a dressing for preventing lip chapping and treating angular lip rot.
Background
The dry lip is a disease, most people can have the dry lip phenomenon more or less in the autumn and winter season because the weather is drier in the autumn and winter season, and often can be windy, people can receive certain damage to their skin when going out without wearing a mask, and many people all gasp with the mouth when tired, and the moisture in the body can also be taken away by the flow of air. If people do not like drinking water or drink too much cold water at ordinary times, the phenomenon of lip chapping is easy to occur, so the method for keeping the lips moist in autumn and winter is mainly to drink more water, but the method cannot be used for some people working outdoors, so the lips are cracked frequently, and in the situation, the lip balm is usually applied to prevent the lips from cracking.
And the lips are still cracked due to the fact that a part of people do not drink water due to the medical advice of a doctor after the operation, and the patient is very difficult to feel under the condition.
The corner ulcer treatment device has the advantages that the corner ulcer of a mouth of a part of people can be cured due to some reasons, most of people need to externally apply ointment to the corner ulcer part under the condition of treating the corner ulcer of the mouth, and the corner ulcer of the mouth can not be bound like other parts, so that the applied ointment can be quickly wiped off by the tongue or hands of a patient, the effect is better only when the ointment is frequently applied, and meanwhile, the inconvenience is brought to the patient.
At present, there is not an article that can be attached to the lips to prevent the lips from drying out or an article that can allow the ointment to adhere to the article and that can be applied to the lips for a long time without affecting life.
Disclosure of Invention
In view of the above, the invention provides a dressing for preventing lip chapping, which can be pasted on the lips, prevent the moisture of the lips from evaporating, avoid the situation of lip chapping, and does not influence the daily life of people.
In order to achieve the purpose, the invention adopts the following technical scheme:
the dressing for preventing lips from being dried and cracked comprises a hydrophilic foam material layer, a PU (polyurethane) film layer, a PET (polyethylene terephthalate) sheet layer and a cover lining film layer, wherein the hydrophilic foam material layer is a water-filling and water-replenishing wet layer, the PU film layer is a moisture-preserving and breathable layer, the PET sheet layer is a shape-maintaining layer, the cover lining film layer is a front protective layer, the hydrophilic foam material layer and the PET sheet layer are positioned on two sides of the PU film layer, the cover lining film layer covers the outer surfaces of the hydrophilic foam material layer and the PU film layer, the hydrophilic foam material layer and the PU film layer are bonded together through a medical adhesive layer, and the rest layers are connected together through static electricity;
hydrophilic foam material layer and PU rete's structural shape is the lip shape, the structural shape of PET lamella and lid lining rete is than hydrophilic foam material layer and PU rete's lip shape one more outstanding sand grip for peel off when lid lining rete and PET rete use.
Further, the thickness of the PU film layer is 0.5-2 microns.
Further, the cover liner film layer is a polypropylene film or a polyethylene film.
Further, the thickness of the hydrophilic foam material layer is 10-500 microns.
Further, the hydrophilic foam material of the hydrophilic foam material layer is a hydrophilic polymer foam made of at least one material selected from the group consisting of LDI, BDI, PDI, HDI, TDI, MDI, NDI, HMDI, and IPDI as a main material.
Further, the density of the hydrophilic foam layer before water absorption is 0.01-0.50g/cm3The water absorption rate is 100-3000%.
Further, the hydrophilic foam material layer is filled with moisture.
Furthermore, the hydrophilic foam material layer can be filled with medicines for treating angular erosion of mouth.
When the dressing for preventing the lips from being dried and cracked is used, the changed lining film layer on the outer side of the hydrophilic foam material layer is firstly torn off, then the hydrophilic foam material layer is contacted with water or liquid medicine or the hydrophilic foam material layer is contacted with water and then solid medicine, the hydrophilic foam material layer is filled with water or the medicine, then the hydrophilic foam material layer is directly contacted with the lips and is pasted on the lips, and the PET film layer and the covering lining film layer are torn off to finish the pasting.
In the process that hydrophilic foam material layer and water or medicine contact, can hold between the fingers the sand grip with the hand, the hand is not in contact with hydrophilic foam material layer, has avoided hydrophilic foam material layer's pollution.
The invention has the beneficial effects that:
1. the dressing for preventing lip chapping of the invention utilizes the water absorption function of the hydrophilic foam material layer, is filled with water before being applied, and then is applied on the lips, thereby effectively supplementing water to the lips.
2. The dressing for preventing lip chapping can fill the hydrophilic foam material layer with the medicament for treating the mouth-rotting corners or coat the medicament on the surface after filling water by utilizing the water absorption effect of the hydrophilic foam material layer, can effectively treat lip diseases such as the mouth-rotting corners and the like, can continuously act in the treatment process, cannot be wiped off by the tongue or hands, and has a good treatment effect.
3. According to the dressing for preventing lip chapping, the PU film layer can prevent the moisture loss of the hydrophilic foam material layer and has a ventilation effect, and the PU film layer is very thin, so that the function of the lip is not influenced after the dressing is applied, and the inconvenience feeling is not generated.
4. The dressing for preventing the lips from being dried and cracked can meet the requirement of the lips for moisture for more than one day after being pasted on the lips, and can be used for a long time, so that the production and life of people are not influenced.
