Abstract An internally-illuminated medical data card in a credit card format containing a summary of the medical history of the bearer germane to his existing medical condition. The card, which is of laminated construction, includes a plastic core panel having light-transmitting properties, one face of the panel having formed thereon a metallized layer functioning as a double-faced mirror. Mounted on the layer and on the other face of the panel, respectively, are front and rear film transparencies containing medical data in a directly legible scale, the combined data affording the required summary. The long edges and one end of the panel are in a concave formation to define reflective convex terminations whereby light entering the remaining flat end is transmitted through the panel and is reflected by the convex terminations and by the inner face of the mirror to provide multiple internal reflection, causing the light to illuminate the front transparency to enhance its readability. And light reflected by the outer face of the mirror serves to enhance the readability of the rear transparency.
A medical data card in credit card format containing a summary of the medical history of the bearer germane to his existing medical condition, the card comprising: (A) a core panel adapted to receive external light incident to an edge thereof and having internal light transmitting properties; (B) a double-faced mirror mounted on one face of the panel whereby the inner face of the mirror abuts said one face of the panel and the outer face of the mirror is exposed to external light; (C) a front transparency containing medical data in a legible scale mounted on the outer face of the mirror and rendered more readable by external light reflected from the outer face toward the front transparency; and (D) a rear transparency containing medical data in a legible scale mounted on the other face of the panel and rendered more readable by said internal light reflected toward the rear transparency by the inner face of the mirror.
