Abstract: The present invention discloses a noninvasive smart glucometer, comprising a near-infrared picture acquisition device and a processor, wherein the near-infrared picture acquisition device is used for acquiring human body's near-infrared pictures, and the processor is used for processing, comparing and calibrating the near-infrared pictures and then outputting the measurement result of a user's blood glucose. While using this glucometer, a blood glucose value can be acquired by putting the near-infrared pictures of human body's specific parts into the processor. This glucometer is easy to use, and may be shared by multiple people, without any consumables or pollutions, which is a real “noninvasive” glucometer.

Abstract: A display prop splicing device includes display bodies, luminous bodies, and connecting bodies. A first mounting site and a second mounting site are respectively formed at two ends of each connecting body. A third mounting site and a fourth mounting site are respectively formed at two ends of each display body. A first magnet and a second magnet which are attracted to each other are arranged in each first mounting site and each third mounting site, as well as in each second mounting site and each fourth mounting site. Conductive poles used for electrical connection between the adjacent display bodies are embedded into the outer edges of each first magnet and each second magnet. At least one display body is electrically connected with an external electrical control device through a power line. Multiple display bodies are conveniently and flexibly spliced through the first, second, third and fourth mounting sites.
