Abstract
A multi-sensor system may include a catheter that has lumen, is flexible, is made of a polymer, and has a circular cross section that has an outer diameter of no more than 0.5 cm; and one or more sensors that sense multiple characteristics of material flowing within the lumen, including at least two of the following: flow rate, pressure, and composition of the material. A multi-sensor system may include a catheter that has lumen, is flexible, is made of a polymer, and has a circular cross section that has an outer diameter of no more than 0.5 cm; and one or more sensors that sense multiple characteristics of material flowing within the lumen, including at least two of the following: flow rate, pressure, and composition of the material.
Claims21
A multi-sensor system comprising:
- a catheter that has lumen, is flexible, is made of a polymer, and has a circular cross section that has an outer diameter of no more than 0.5 cm;
- and
- one or more sensors that sense multiple characteristics of material flowing within the lumen, including at least two of the following:
- flow rate, pressure, and composition of the material.
A flow sensor system comprising:
- a sensor that senses material flow;
- a fluid disrupter that transiently perturbs the electrochemical impedance of material flowing by the sensor;
- and
- one or more electrodes that measure the electrochemical impedance of material flowing by the sensor.
The flow sensor system of claim 20 wherein the gas bubble generator generates one or more gas bubbles using electrolysis driven by at least two electrodes.
