Description

Phase-change constant-temperature application eye patch

Technical Field

The application specifically discloses phase transition constant temperature pastes eye-shade.

Background

With the rapid development of modern social science and technology, computers and mobile phones become an integral part of people's life and work, and the eye pain and other eye diseases are easily caused by long-term use of computers or mobile phones, which leads to the continuous increase of myopia rate for a long time. Although many people choose to solve the myopia problem through surgery, the eyes also have symptoms such as dryness and aching pain during the postoperative recovery process.

In the medical field, one particularly typical scenario is the use of constant temperature cold/hot compress to mitigate myopia risk. Clinical experience proves that cold compress and hot compress both have obvious effect on controlling visual fatigue, particularly preventing myopia of teenagers. The hot compress at high temperature can accelerate blood circulation, and is beneficial to restoring the endurance of ciliary muscle and muscles around eyes during long-time reading and learning; the cold compress at low temperature can relax ciliary muscle and muscles around eyes, and assist rapid relaxation after high-strength eyes are used.

The temperature of cold compress and hot compress has obvious effect, namely, cold injury can be caused by low temperature (such as ice bags), scald can be caused by high temperature (such as towel scalding), and no obvious effect is caused by medium temperature. Because the eye is extremely sensitive and fragile, it is much weaker than other tissues in its ability to withstand high and low temperatures. Generally, cold compress is about 4 degrees, and hot compress is about 40 degrees. Meanwhile, the cold compress and the hot compress are kept for 5 to 15 minutes. Since the ambient temperature and the body surface temperature are usually much higher than 4 degrees and much lower than 40 degrees, the hot or cold compress condition is rapidly broken without active temperature control, and the expected effect is not achieved.

Various cold/hot compress eyepatches exist in the market at present, the principle of the cold compress eyepatch is simple, the cold compress eyepatch is mostly realized by filling an ice bag in the eyepatch, and the temperature of the ice bag is usually 0 ℃ or below and is used for causing injury to eyes by cold compress. The steam eye patch in the hot compress eye patch is most popular, but the eye patch is mostly disposable.

Such as: in ZL201310124891.7, a steam hot compress eye patch generates heat through reaction of a metal powder heating element inside the eye patch and oxygen in the air, and then water absorbed by resin inside the eye patch is evaporated through heat to generate fine and warm water vapor. The product can continuously generate heat for 15-30 minutes at 40-45 deg.C, and has certain effect in improving eye dryness. But this eye-shade on the one hand inside uses is powdered object, the problem that can appear falling the bag, leak the powder, and this steam eye-shade on the other hand is disposable product owing to metal powder heat-generating body self, just need abandon after the disposable, has caused the waste of resource, is unfavorable for the protection of environment. In addition, a common hot compress eyeshade on the market is heated by a heating sheet, and the eyeshade needs to be externally connected with a power supply all the time, so that the use is inconvenient, and the danger of electric leakage exists.

For another example: the phase-change hot compress eye cover of patent No. 201711018545.5 and the passive constant temperature system and the constant temperature preparation device thereof of patent No. 201910978110.8 both realize the long-time cold/hot compress effect of the eye cover by adding phase-change materials into the eye cover. The former is to add phase-change heat storage material with phase-change temperature of 40-80 deg.C, and to use external power supply to heat the phase-change material to phase-change point, and then to remove the power supply for use. The latter is to add phase-change heat storage materials with phase-change temperature of 0-8 ℃ or 40 ℃, respectively invent cold/hot compress eyepatches, realize temperature reduction/temperature rise through cold and heat exchange with an external cold/heat source, and then use. The phase-change materials are used in both eye patches, but when the temperature is lower than the phase-change temperature, the used phase-change materials (such as polyethylene glycol 1000, melting point 38 ℃) become hard solids, so that the phase-change materials are not well attached to eyes and even hurt the eyes, in addition, most of the phase-change materials are organic matters, the heat conductivity is very poor, a phenomenon of local overheating can occur in the heating/heat release process, the chemical properties of some organic phase-change materials are unstable, and if leakage occurs, the phase-change materials can harm human bodies. There is therefore a need for a new cold/hot compress eye shield that solves the above problems.
