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.

Example Embodiment

[0037] Example 1

[0038] Non-invasive blood sugar monitoring device, such as figure 1 As shown, including a nozzle 1 which can be attached to the skin for collecting body fluids, an electronic detecting module 2 for detecting body liquid blood sugar value is mounted inside the claim 1 and a negative pressure for the nozzle 1. Pressure pump 3; the nozzle 1 is in communication between the negative pressure pump 3.

[0039] After the negative pressure pump 3 is opened, the nozzle 1 provides a negative pressure, and the suction nozzle 1 draws the body fluid of the skin surface under negative pressure, and the body fluid is immersed after the electronic detection module 2, the electronic detection module 2 outputs the electrical signal to realize the detection of blood sugar. The entire testing process is non-invasive testing.

[0040] Specifically, the nozzle 1 is like Image 6 As shown, including the type 1-1 of the flared shape of the skin contact, is used to accommodate the detection zone 1-2 of the electronic detecting module 2 and the joint zone 1-3 connected to the air conductor 4;

[0041] In order to satisfy the purpose of multiple detection of the patient, the number of the nozzle 1 in this embodiment is four, and an electronic detection module 2 is mounted in each of the nozzles 1. Alternatively, the number of nozzle 1 can be appropriately adjusted according to the monitoring needs.

[0042] like figure 2 and image 3 As shown, the four of the nozzle 1 and the negative pressure pump 3 are selectively turned on by a conductive selector 5; the conduction selector 5 includes a ring-shaped first body 5-1 and a rotatable The second body 5-2; four holes are opened on the annular side wall of the first body 5-1, each with a guided pipe branch 4-1, the first body 5-1 passing four The aperture and the four air pipe branch 4-1 communicate with four nozzles 1; the second body 5-2 is a L-shaped bend, the upper opening and air conduit 4- of the second body 5-2 2 between two rollers 11 is rotated; and the lower opening of the second body 5-2 is rotated to interface with a certain hole on the first body 5-1 annular side wall, and the on-selector 5 and a certain suction The selective communication of the mouth 1. The first body 5-1 and the second body 5-2 remain a closed connection during the rotation.

[0043] In order to realize the automatic switching of four nozzle 1, the second body 5-2 is driven into the motor 6. Under the driving of the stepping motor 6, the second body 5-2 is rotated to a particular position, and the openings below the air supply pipe branch 4-1 at this position. The entire driver process is controlled by electronic control module.

Example Embodiment

[0044] Example 2

[0045] This embodiment describes the detailed structure of its negative pressure pump based on the first embodiment.

[0046] The negative pressure pump 3 is like Figure 4 and Figure 5 As shown, including a negative pressure step motor 3-1, a triangular rotor 3-2, and a pump chamber 3-3; the triangular rotor 3-2 and the negative pressure step motor 3-1 pass through the eccentric shaft 3- 4 Drive connections; the pump chamber 3-3 consists of two chambers of the left and right symmetrical; the triangular rotor 3-2 divides one of the chambers in the positive pressure region A and a negative pressure region B during rotation. . For example, when the negative pressure stepping motor output torque, the eccentric shaft 3-4 drives the triangular rotor 3-2 timing to rotate, so that the positive pressure above the left chamber becomes positive pressure region A, so that a negative pressure is produced under the left chamber. Become a negative pressure region B.

[0047] The positive pressure region A is provided with an exhaust hole 3-5; the negative pressure region B is provided with an intake hole 3-6; the air intake hole 3-6 is passed between the air conductors 4-2 The intake pipe 3-7 is connected.

[0048] Under the driving of the negative pressure stepping motor, the triangular rotor 3-2 is rotated, and one of the chambers is divided into positive pressure regions A and the negative pressure region B. The negative pressure region B is sequentially passed through the intake hole 3-6, the intake pipe 3-7, the guide tube main pipe 4-2, the air conducting tube branch pipe 4-1 is in communication, and the suction nozzle 1 reaches the negative pressure state. When the detection is completed, the negative pressure stepping motor 3-1 is rotated counterclockwise, the original positive pressure region A is turned a negative pressure, absorbed by the exhaust hole 3-5; the negative pressure region B and its communication nozzle 1 restore Pneumatic balance.
