This product is composed by 3 parts, gel, whale print and PVA protective layer. Gel keeps exactly same as traditional gel patches did. It is still most important part as it's water vaporization brings down fever.
But our product has two outstanding advantages.
First, thermochromic whale print. It works as an alarm to guardian of high fever risk on patient. The pink whale disappears if body temperature exceed 38.5℃, but it appears gradually as the abatement of fever. This design is unique on our gel patch and been patented. As far as we know, there is no other similar product on the market.
Second, transparent perforated PVA film. It has replaced non woven fabric which used on traditional ones. Transparent character is a technical need, as the guardian need to see whale print and its changes under this film. Non woven fabric will never transparent. What is more, the ventilated pores on PVA film will accelerated the abatement of fever during water vaporization, which we can not expect on non woven fabric. There is no other gel patch on market use PVA perforated film neither.
