Abstract
The invention discloses a non-invasive blood glucose monitoring device and a wearable non-invasive blood glucose meter. The non-invasive blood glucose monitoring device comprises a suction nozzle used for collecting body fluid, an electronic detection module installed in the suction nozzle and used for detecting the blood glucose value of the body fluid, and a negative pressure pump providing negative pressure for the suction nozzle. The suction nozzle is communicated with the negative pressure pump through an air guide pipe; the negative pressure pump comprises a negative pressure stepping motor, a triangular rotor and a pump cavity; the triangular rotor and the negative pressure stepping motor are in driving connection through an eccentric shaft; the pump cavity is composed of two cavities which are symmetrical left and right. One of the cavities is divided into a positive pressure area and a negative pressure area by the triangular rotor in the rotating process; the negative pressure area is communicated with the suction nozzle so as to provide negative pressure for the suction nozzle.
