Infinite-Warmth / Healthcare


Saline bottle is often stored in refrigerator for medical drugs prior to use, in order to maintain its pharmaceutical activity. And it would only be taken out from below 8 Celsius degree just before used for hang drip, and when the ice-cold saline flow into the patient’s vein, it would feel piercingly cold. To address this issue, we designed a convenient heating strip for patients suffering from cold saline to get rid of such extra pain. It fits various type of saline bottle or bags; the thermal gel would provide 8 hours of heating capacity at 45 about Celsius degree after being heated in a microwave oven for 2min.
