Embodiment 1

[0038] A non-invasive blood glucose monitoring device, such as figure 1 As shown, it includes a suction nozzle 1 that can be attached to the skin for collecting body fluids, an electronic detection module 2 installed inside the suction nozzle 1 for detecting the blood glucose level of the body fluid, and a negative pressure device that provides negative pressure for the suction nozzle 1. A pressure pump 3; the suction nozzle 1 communicates with the negative pressure pump 3 through an air guide tube 4.

[0039] After the negative pressure pump 3 is turned on, it provides negative pressure for the suction nozzle 1, and the suction nozzle 1 absorbs the body fluid on the skin surface under the negative pressure. The whole detection process is non-invasive detection.

[0040] Specifically, the suction nozzle 1 is as Figure 6 As shown, it includes a trumpet-shaped collection area 1-1 in contact with the skin, a detection area 1-2 for accommodating the electronic detection module ...

Embodiment 2

[0045] This embodiment introduces the detailed structure of its negative pressure pump on the basis of Embodiment 1.

[0046] The negative pressure pump 3 is as Figure 4 and Figure 5 As shown, it includes a negative pressure stepping motor 3-1, a triangular rotor 3-2 and a pump chamber 3-3; the triangular rotor 3-2 and the negative pressure stepping motor 3-1 pass through an eccentric shaft 3- 4 drive connection; the pump chamber 3-3 is composed of two symmetrical chambers; the triangular rotor 3-2 divides one of the chambers into a positive pressure area a and a negative pressure area b during rotation . For example, when the negative pressure stepper motor outputs torque, the eccentric shaft 3-4 drives the triangular rotor 3-2 to rotate clockwise, so that positive pressure is generated above the left chamber to form a positive pressure area a, and negative pressure is generated below the left chamber Become a negative pressure area b.

[0047] The positive pressure are...

Embodiment 3

[0050] A wearable non-invasive blood glucose meter, such as figure 1As shown, it includes a housing 7, an electronic screen 8, a strap 9 and the non-invasive blood sugar monitoring device as described in Embodiment 1 or 2; the non-invasive blood sugar monitoring device is installed inside the housing 7, wherein the collection area 1 of the suction nozzle 1- 1 is located outside the casing 7; the electronic screen 8 is installed on the outer surface of the casing 7.

[0051] The shell 7 is as Figure 7 As shown, its upper surface 7-1 is a plane for installing an electronic screen 8; its lower surface is provided with four grooves 7-2 for installing a suction nozzle 1;

[0052] Such as Figure 8 As shown, an annular protrusion 15 is provided on the inner wall of each said groove 7-2; a rubber ring 16 is installed on the outer wall of said suction nozzle 1; when installing, the suction nozzle 1 is inserted into the groove 7-2 , the rubber ring 16 is sealingly engaged with the ...

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.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a noninvasive blood glucose monitoring device and a wearable noninvasive blood glucose meter. Background technique [0002] With the development of society, diabetes has gradually become a major killer threatening human health. Blood sugar monitoring is an important task in the daily maintenance of diabetes. [0003] Traditional blood sugar monitoring instruments use a disposable blood collection needle to puncture the skin, then dip the blood into a test paper, and detect it through a certain testing device to obtain the blood sugar value at a certain moment. [0004] Traditional blood glucose monitoring instruments are as follows: [0005] 1. Invasive blood collection increases the suffering of patients and also has the risk of blood infection; [0006] 2. Intelligently obtain the blood sugar level at a certain moment, but it is impossible to monitor the blood sugar ...
