When the dynamic blood sugar monitoring device is used, the back patch 13 can be firstly adhered and fixed to the epidermis of a human body through the adhesive layer on the bottom surface of the bottom plate 131, and the probe assembly 2 is assembled into the probe mounting cavity through the opening on the bottom of the main shell; the main housing is then assembled to the back patch 13, and when the main housing is assembled to the back patch 13, the front end of the glucosidase microelectrode needle 23 of the probe assembly 2 is passed through the opening 1311 of the bottom plate 131 of the back patch 13 and punctures the epidermis of the human body. When the main housing is assembled to the back patch 13, the main housing may be engaged with the side plate 131 of the back patch 13 so that the glucosidase microelectrode needles 23 in the probe assembly 2 reach predetermined positions on the human epidermis in a perpendicular manner to the human epidermis.
The dynamic blood sugar monitoring device guides the glucolase micro-electrode needle 23 on the probe component 2 to be inserted into the subcutaneous part of a human body in a vertical mode through the matching of the side plate 132 of the back patch 13 and the main shell, so that the dynamic blood sugar monitoring device can be worn in place, and the replacement operation of the probe component 2 is facilitated.
In particular, the front end of the micro-electrode needle 23 protrudes from the bottom surface of the back patch 13 by 4.3-4.9 mm, so as to pierce the stratum corneum and epidermis layers of the skin to reach the dermis layer, and to generate an oxidation reaction with the glucose of the human body and form electrical signals (low voltage and low current signals), and the circuit board 14 in the main housing can process the electrical signals and generate corresponding blood glucose data.

Specifically, the upper surface of the bottom cover 12 may have a plurality of vertically upwardly extending snaps 122, and accordingly, the inner surface of the side walls of the upper cover 11 may have snap holes, and the upper cover 11 and the bottom cover 12 may be fixed together by the mating of the snaps 122 with the snap holes.
In addition, the outer surface of the side wall of the upper cover 11 has a hook 111, and accordingly, the inner side of the side plate 132 of the back patch 13 has a slot 1321, and the main housing is fitted to the back patch 13 in such a manner that the outer surface of the side wall of the upper cover 11 is closely attached to the inner surface of the side plate 132 of the back patch 13, and is fixed with the back patch 13 by the engagement of the hook 111 and the slot 1321. To facilitate the removal of the main housing from the back patch 13, the hooks 111 may be formed by protruding ribs (parallel to the lower surface of the bottom cover 12) on the outer surface of the side wall of the upper cover 11.
The socket of the probe assembly 2 may specifically include a socket upper cover 21 and a socket lower cover 22 that are engaged with each other, and the socket lower cover 22 has two nut posts 221 extending toward the socket upper cover 21, and the socket upper cover 21 and the socket lower cover 22 are fixed by screws 29 screwed to the nut posts 221. In addition, a cap 28 may be provided on the sleeve cover 21 to conceal the screws 29 for an aesthetic purpose of the probe assembly 2.
And the probe assembly 2 further comprises a fixed seat 25 and two pressing blocks 26 (the fixed seat 25 may be made of an insulating material, and the pressing blocks 26 may be made of a conductive material), and the fixed seat 25 and the pressing blocks 26 are both located in the cavity between the sleeve upper cover 21 and the sleeve lower cover 22. Two probe holes are formed in the sleeve bottom cover 22, and two glucolase micro-electrode needles 23 respectively penetrate through the probe holes and then are tightly pressed and fixed between the two nut columns 221 through two pressing blocks 26 and a fixing seat 25. The two spring pins 24 are each electrically conductively connected to a pressure piece 26, so that each spring pin 24 is electrically conductively connected to a glucoamylase microelectrode 23.
The sleeve bottom cover 22 has one or more elastic arms 222 extending vertically upward (the elastic arms 222 are uniformly distributed along the circumferential direction), and the free end of each elastic arm 222 protrudes in the direction away from the central axis; the side wall of the sleeve upper cover 21 is provided with a plurality of first gaps 211 corresponding to the elastic arms 22 and a plurality of second gaps 212 corresponding to the positions of the elastic pins 24.

And since the free ends of the resilient arms 222 project away from the central axis, the free ends of the resilient arms 222 project out of the side walls of the sleeve. Thus, when the sleeve is assembled to the probe mounting cavity of the main housing, the free ends of the resilient arms 222 can press against the side walls of the probe mounting cavity, stabilizing the sleeve within the probe mounting cavity.
And each of the elastic pins 24 includes a metal cap, a metal seat and an elastic member (e.g., an elastic piece or a spring). The metal cap is mounted on the metal holder and pushed to the outside of the sidewall of the cartridge bottom cover 22 by the elastic member. Thus, during insertion assembly of the probe assembly 2 into the host, the metal cap is forced to retract back into the sleeve and force the resilient member to deform and push the metal cap outward when the probe assembly 2 is fully inserted into the host, thereby bringing the metal cap into stable contact with the resilient contact 15 in the probe mounting cavity of the main housing.
In addition, the outer surface of the side wall of the sleeve upper cover 21 can also be provided with a rib which is axially arranged, and the side wall of the probe installation cavity of the main shell body is provided with a groove which corresponds to the rib, so that when the probe assembly 2 is assembled in the probe installation cavity, the probe assembly 2 can be prevented from rotating in the probe installation cavity.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
