Abstract
A sensor is provided that is appropriate for transcutaneous detection of tissue or blood constituents. A sensor for tissue constituent detection may include a gas collection chamber with a conduit to a sensing component and a conduit from the sensing component to the chamber. A sensor as provided may also include a barrier layer to prevent water from infiltrating the sensor.
Claims20
A system comprising:
- a coiled conduit permeable to a tissue constituent, wherein the coiled conduit is adapted to be placed proximate to a tissue;
- an efferent conduit in fluid communication with the coiled conduit, wherein the efferent conduit is adapted to transfer the tissue constituent from the coiled conduit to at least one sensing component, wherein the sensing component is adapted to provide a signal related to the tissue constituent;
- an afferent conduit adapted to transfer the tissue constituent from the sensing component to the coiled conduit;
- and
- a motive force structure adapted circulate the tissue constituent through the system, wherein the motive force structure is adapted to be operatively connected to at least one of the efferent conduit, the afferent conduit, or the sensing component.
2 more elements
A sensor comprising:
- a gas collection structure adapted to be placed proximate to a tissue, wherein the gas collection structure comprises a coiled tube or a folded tube, and wherein the coiled or folded tube is at least partially permeable to a tissue constituent;
- and
- an efferent conduit adapted to transfer the tissue constituent from the gas collection structure to a sensing component, wherein the sensing component is adapted to provide a signal related to the tissue constituent;
- and
- an afferent conduit adapted to transfer the tissue constituent from the sensing component to the gas collection structure.
2 more elements
A sensor, comprising:
- a gas collection structure adapted to be placed proximate to a tissue, wherein the gas collection structure comprises a coiled tube or a folded tube at least partially permeable to a gaseous tissue constituent;
- and
- a sensing component associated with the gas collection structure, wherein the sensing component is adapted to provide a signal related to the gaseous tissue constituent.
