Device and method for removing liquid from endogenic tissue and determining the concentrations of substance in said liquid
First Claim
1. Device for removing liquid from endogenic tissue and determining concentrations of substances in this liquid, in which at least one hollow chamber (3) having at least one contact opening (3.1) disposed on a contact surface (3.2) is placeable in direct contact on the skin (1) covering the tissue, and the hollow chamber (3) is connected to a low pressure-producing element (P) via a channel (4.1).

Abstract
The present invention relates to a device for removing liquid from endogenic tissue and determining concentrations of substances in this liquid, in which a hollow chamber (3), which is placeable in direct contact on the skin (1) covering the tissue with at least one contact opening (3.1) disposed on a contact surface (3.2) and the hollow chamber (3) is connected to a low pressure-producing element (P) via a channel (4.1).

25. Method for removing liquid from endogenic tissue and determining concentrations of substances in this liquid,
in which a device having at least one contact opening configured on at least one hollow chamber (3) in a contact surface (3.2) is placed on the skin surface, a low pressure is set in the hollow chamber (3) and, as a result of the low pressure effect, a liquid reservoir (1.4) is formed underneath the surface (1.1) of the skin as a result of the pressure difference; - and
the liquid which is collected in the liquid reservoir (1.4) and subsequently flows out of the tissue is guided by suction forces occasioned by low pressure to a sensor (6) or a sensor system (12, 13, 27, 27′
