Embodiment 1

[0032] This embodiment provides a microneedle electrode with limited penetration depth, such as figure 1 and Figure 5 , including a microneedle body, the microneedle body includes a needle tip area 1 arranged at the front end of the micro needle body, and a boss area 2 arranged at the rear end of the needle tip area with a radius greater than that of the needle tip area.

[0033] Further, a transition area 3 is also provided between the boss area and the needle tip area; the radius of the transition area gradually increases from one end of the needle tip area to one end of the boss area.

[0034] Further, the microneedle body is made of tungsten copper alloy.

[0035] Further, the surfaces of the tip area and the transition area are covered with a sensitive layer; the sensitive layer is an electrode active material sensitive to glucose.

Embodiment 2

[0037] This embodiment provides a microneedle electrode with a limited penetration depth, including a microneedle body, the microneedle body includes a needle tip area disposed at the front end of the microneedle body, and further includes a boss disposed at the rear end of the needle tip area with a radius larger than the needle tip area Area.

[0038] Further, a transition area is also provided between the boss area and the needle tip area; the radius of the transition area gradually increases from one end of the needle tip area to one end of the boss area.

[0039] Further, the microneedle body is made of copper material.

[0040] Further, the surfaces of the tip area and the transition area are covered with a sensitive layer; the sensitive layer is an electrode active material sensitive to alcohol.

Embodiment 3

[0042] This embodiment provides a microneedle electrode with a limited penetration depth, including a microneedle body, the microneedle body includes a needle tip area disposed at the front end of the microneedle body, and further includes a boss disposed at the rear end of the needle tip area with a radius larger than the needle tip area Area.

[0043] Further, a transition area is also provided between the boss area and the needle tip area; the radius of the transition area gradually increases from one end of the needle tip area to one end of the boss area.

[0044] Further, the microneedle body is made of any one of platinum, silver, gold, copper, and tungsten.

Abstract

The invention discloses a tungsten alloy micro-needle electrode capable of limiting the piercing depth, a preparation method thereof, and a blood glucose monitoring device. According to the invention, a boss area can increase the resistance of the body of a micro-needle when entering skin, so that the micro-needle cannot pierce the skin further. Through arrangement of the boss, the depth of the micro-needle electrode piercing the skin can be effectively controlled, so that problems such as infection and allergy caused by too deep piercing into the skin of the micro-needle electrode can be avoided, and the safety and comfort of a detection device can be improved.

Description

technical field [0001] The invention relates to the technical field of biochemical analysis, in particular to a tungsten alloy microneedle electrode with limited penetration depth, a preparation method thereof and a blood glucose monitoring device. Background technique [0002] Micro needles generally refer to needle-like structures made by micro-fabrication, with a size in the micron level, a diameter of 30-80Lm, and a length of more than 100Lm. The material can be silicon, polymer, metal, etc. Microneedles have a wide range of applications in the biomedical field, such as biomedical measurement systems, drug delivery systems, and microsampling and analysis systems. Microneedles are not only small in size, but also have characteristics unmatched by conventional methods in terms of performance—precise, painless, efficient, and convenient. This greatly promotes the development of biomedicine and makes the instruments in this field more humanized. Microneedles can easily pen...
