Problems solved by technology

[0005] However, the existing physiological detection equipment cannot be used for a long time. For example, the transdermal sensor can only detect a single time. If a new transdermal sensor needs to be re-tested, the detected data will be directly transmitted to the reader or mobile phone, the transdermal sensor itself does not store data
In addition, the existing physiological detection equipment cannot interrupt the detection midway during continuous detection for a period of time, which has the disadvantage of wasting system power, and frequent replacement of transcutaneous sensors also wastes resources.

Embodiment Construction

[0044] The implementation of the present invention will be described below by specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification, and can also be improved by other different specific examples. implement or apply.

[0045] see figure 1 , figure 2 and image 3 , the transdermal microneedle array patch 1 of the present invention includes a lower cover 11 and an upper cover 12 . The lower cover 11 has a first surface 111 and a second surface 112 opposite to the first surface 111 , and the first surface 111 is provided with a metal sheet 113 . A substrate 14 is disposed inside the upper cover 12 , and the substrate 14 has two probes 13 exposed on the inner surface 121 of the upper cover 12 , wherein the two probes 13 are disconnected from each other.

[0046] In one embodiment, the two probes 13 may not be arranged on the substrate 14 at the same t...

Abstract

Provided is a transdermal microneedle array patch, including: a bottom cover; a top cover; a substrate disposed within the top cover; and a first probe and a second probe disposed between the bottom cover and the top cover and electrically connected the substrate. The first and second probes form an open circuit. While the bottom cover is combined with the top cover to form the transdermal microneedle array patch, the first and second probes form a closed circuit.

Description

technical field [0001] The invention relates to a percutaneous microneedle array patch, in particular to a disposable percutaneous microneedle array patch. Background technique [0002] The interstitial fluid of the human body mainly flows in the subcutaneous tissue. Since interstitial fluid is rich in amino acids, fatty acids, sugars, salts, hormones, coenzymes, and wastes produced by cells, the physiological status of the human body can be effectively judged by analyzing the concentration of each component in interstitial fluid. [0003] For another example, when taking or injecting drugs, the drugs will also be released slowly in the interstitial fluid for a long time, and there will be changes in concentration. Therefore, analyzing the drug concentration in the interstitial fluid can also effectively monitor the efficacy of the drug. [0004] Existing physiological detection equipment mostly uses needles to puncture the stratum corneum to extract interstitial fluid for ...
