Title
(EN) MEDICAL WRISTBAND WITH INVISIBLE INFORMATION AND PREPARATION METHOD THEREOF
Abstract
(EN)

The present invention relates to a medical wristband with invisible information and a method for manufacturing the same. The conventional developed dyes or inks in the prior art can store information which, however, is visible. In the present invention, polystyrene (PS) microspheres are prepared by micro-emulsification: PS particles are dissolved in a toluene solution and a fluorescent dye is added to obtain a fluorescent solution; an SDS solution is added in and mixed with the fluorescent solution to obtain a system to be ultrasonically emulsified; and the system is ultrasonically emulsified and the toluene is completely volatilized. The ink can be used directly as an invisible ink. The information is written, as two-dimensional codes and by the ink, on a piece of non-fluorescent paper, and plastic-packaged onto a wristband of a patient. Information about a patient can be successfully scanned in the ease of UV on.
