Abstract
A cannula sensing system and method include a cannula having at least one biosensor configured to detect a level of one or more biomarkers in blood within a blood vessel of a patient. The biosensors are arranged at or near a distal end of a cannula inserted within the blood vessel. The biosensor may be connected to a wire arranged on and/or within a wall of the cannula.
Claims27
A cannula sensing system comprising:
- a cannula having a distal end defining an opening;
- one or more biosensors arranged on and/or within an outer wall of the cannula;
- and
- a memory storage device embedded in the cannula;
- wherein the one or more biosensors are configured to generate biosensor data based on a detected level of one or more biomarkers in blood;
- wherein the cannula is configured to deliver intravenous medication and/or fluid materials into a blood vessel simultaneously while the one or more biosensors are detecting the detected level of the one or more biomarkers in blood;
- wherein the biosensor data is configured to be stored in the memory storage device of the cannula;
- wherein the outer wall of the cannula defines a groove extending in a longitudinal direction of the cannula, and the one or more biosensors are arranged within the groove which allows for free blood flow past each biosensor;
- wherein one or more parts of the groove comprises an intermediate portion having a larger width and/or depth than areas of the groove outside of the intermediate portion, and the one or more biosensors are arranged in the intermediate portion;
- and
- wherein the intermediate portion and the areas of the groove outside of the intermediate portion each have a longitudinal extension extending in the longitudinal direction.
8 more elements
A set of cannula sensing systems comprising:
- a plurality of cannulas, each cannula of the plurality of cannulas including a biosensor arranged on and/or within an outer wall of the respective cannula and a memory storage device embedded in the cannula, and each cannula having a distal end defining an opening;
- wherein each biosensor of each cannula of the plurality of cannulas is configured to generate biosensor data based on a detected level of one or more biomarkers in blood;
- wherein the one or more biomarkers is different for each cannula of the plurality of cannulas;
- wherein each cannula is configured to deliver intravenous medication and/or fluid materials into a blood vessel simultaneously while the one or more biosensors for the respective cannula are detecting the detected level of the one or more biomarkers in blood;
- wherein the outer wall of each cannula defines a groove extending in a longitudinal direction of the respective cannula, and the one or more biosensors of each cannula are arranged within the respective groove which allows for free blood flow past each biosensor;
- wherein one or more parts of each groove comprises an intermediate portion having a larger width and/or depth than areas of the respective groove outside of the intermediate portion, and the one or more biosensors of each cannula are arranged in the respective intermediate portion;
- and
- wherein the intermediate portion of each cannula and the areas of the groove outside of the intermediate portion of each cannula each have a longitudinal extension extending in the longitudinal direction of the respective cannula.
5 more elements
A method of using a cannula sensing system comprising:
- inserting a distal end of a cannula into a blood vessel of a patient, the cannula including a biosensor arranged on and/or within an outer wall of the cannula configured to detect a biomarker in blood;
- delivering intravenous medication and/or fluid materials into the blood vessel through the cannula;
- detecting, with a biosensor, a biomarker in blood within the blood vessel;
- and
- storing biosensor data in a memory storage device embedded in the cannula;
- wherein the delivering and the detecting occur simultaneously;
- wherein the outer wall of the cannula defines a groove having a longitudinal extension extending in a longitudinal direction of the cannula, and the biosensor is arranged within the groove which allows for free blood flow past the biosensor;
- wherein one or more parts of the groove comprises an intermediate portion having a larger width and/or depth than areas of the groove outside of the intermediate portion, and the biosensor is arranged in the intermediate portion;
- and
- wherein the intermediate portion and the areas of the groove outside of the intermediate portion each have a longitudinal extension extending in the longitudinal direction.
