This is an improved design of infusion set for security reminder.
The color of current infusion set is close to the fluid inside it, therefore, it is hard to judge where the liquid level is, which make patients anxious.
This design adds diagonal strip on the back of label of the infusion set. According to the light refraction principle, pattern will be amplified when passing through liquid, or else, it makes no change. The obvious demarcation line produced thereby is to remind patient and their relatives or the nurses that the patient needs to withdraw needles or change medicine. It is also obvious even in a far distance.
