Embodiment Construction

[0046] Overall architecture

[0047] refer to Figure 1 to Figure 4 , the present invention relates to an electronic body monitoring system 1 . This electronic body monitoring system is an improvement on the device in document WO2018104647. Thus, the present invention falls within the same basic concept of a reusable autonomous integrated system with low pain and low hygiene risk.

[0048] "Body monitoring" refers to the verification of biochemical constants of the person wearing the system 1 , typically the concentration of proteins, hormones, markers, oxygen, nutrients, etc. in the interstitial fluid of the person. The example of blood sugar can be cited. Those skilled in the art will be able to monitor other physical quantities of the body (eg, lactate, water content, etc.) if desired.

[0049] The description will be illustrated with interstitial fluid, but applies to other bodily fluids, such as blood.

[0050] System 1 is said to be autonomous in that the system doe...

Abstract

The invention concerns an assembly comprising a patch (250) for a body-monitoring system and a capsule (220). The patch comprises a main body (251) with an opening (252) of at least 2 mm diameter, the main body comprising a rigid zone (256) around the opening and a flexible zone (258) on either side of the rigid zone and preferably all around the rigid zone. The capsule is configured to be placed in the opening of the patch and to be rigidly attached to same, the capsule comprising microneedles (210) configured to be inserted in the skin in order to sample or analyse a bodily fluid of the wearer of a body-monitoring system when said system is positioned on a limb of a user, the rigid zone of the capsule enabling a transmission of the forces received by the patch to the capsule.

Description

technical field [0001] The present invention relates to a body monitoring system for body fluid analysis, typically interstitial fluid analysis, by using microneedles. [0002] More specifically, the present invention relates to a patch for administering and maintaining microneedles in the skin. Background technique [0003] Some conditions such as diabetes require daily monitoring of biochemical parameters of the body, ie the concentration of some compounds (blood sugar exemplified by glucose). [0004] To this end, a point of skin is usually punctured to bead a drop of blood, and the drop is analyzed reactively (e.g., with a test strip) or electronically (e.g., by at least one analytical sensor) in order to estimate one or more target parameters. [0005] Less invasive, advanced systems known today can simply analyze interstitial fluid, the fluid that fills the space between capillaries and cells. The fluid does have an ionic composition close to that of blood plasma. ...
