AI Technical Summary

Technical Problem

Existing blood glucose monitoring devices have complex structures, high processing and assembly precision requirements, and poor guiding effect of the puncture needle, which causes the puncture needle to shake easily during movement and increases the user's pain.

Method used

The design of the limiting sleeve and the clamping part is adopted, and the clamping part clamps the puncture unit in the limiting channel to realize the driving and needle withdrawal movement of the puncture unit, simplify the structure, reduce the processing and assembly precision requirements, and improve the guiding effect.

Benefits of technology

The stable movement of the puncture unit is achieved, which reduces the production difficulty, improves the production efficiency, reduces the user's pain, and ensures the reliability and smoothness of the implantation process.

Abstract

Disclosed in the present application is an in-vivo blood glucose monitoring device, which comprises a housing, a limiting sleeve, and a needle-assist unit. The housing is provided with a first end and a second end which are oppositely arranged along a first direction. The limiting sleeve is provided with a limiting channel extending along the first direction. A puncture unit is used for inserting a sensor part into the host's body. The needle-assist unit comprises at least two clamping parts. The clamping parts are located on the outer sides of the puncture unit to limit movement of the puncture unit, and the clamping parts are located in the limiting channel and are movable along the first direction. When the clamping parts move to a release position, the clamping parts release the puncture unit, such that the puncture unit moves along a second direction. The second direction is opposite to the first direction. The clamping parts clamp and release the puncture unit from the outer side, thereby driving the puncture unit while limiting and triggering a needle withdrawal motion. This design simplifies the structural configuration of both the needle-assist unit and the puncture unit, reduces the production difficulty, improves the production efficiency, and ensures the smoother switching between needle insertion and withdrawal without any sense of jamming.
