Additionally, a controller may be in communication with the first and second sensors where the controller is programmed to correlate pressure oscillations in the airway pressure with heartbeats.

A material, article, system and method include a probe composition that includes a hydrophobic portion, a hydrophilic portion, an analyte-binding portion and a fluorophore portion. The analyte-binding portion is configured to bind to an analyte in an aqueous solution. The fluorophore portion is configured to change an optical property of fluorescent light emitted in response to incident excitation light when the probe composition changes between a first state in which the analyte is not bound to the analyte-binding portion and a second state in which the analyte binds to the analyte-binding portion. A material includes the probe composition and a silicone hydrogel substrate having a hydrogel network that allows flow of aqueous solution through the solution and a silicone network that occupies interstices of the hydrogel network. A contact lens having the material enables remote detection of glucose concentration in tear fluid of a subject.

A reusable and electrochemically active device 100 is provided comprising, detachable electrode arrangement including working electrodes 101a, 101b, 101c, 101d and a counter electrode 102 that are functionalised with selected electrochemically active receptor(s) that can interact with at least a target bioanalyte. Fluid transportation channels 108a, 108b, 108c, 108d are formed, to receive biological samples with the at least target bioanalyte and for further transportation to the selected electrode arrangement, preferably in a sequential manner, for measuring the concentrations of the target bioanalytes. Used working electrodes 101a, 101b, 101c, 101d and a partial portion of the counter electrode 102 are detachable from the device 100. Insulating members 113a, 113b, 113c, 113d, 113e, 113f, 113g are disposed on the electrode arrangement such that the integrity of the electrical connectivity of the remaining electrode arrangement is retained even after the detachment of the used working electrodes 101a, 101b, 101c, 101d and a portion of the counter electrode 102. The present invention also provides a point-of-care biosensor 300 and a method to electrochemically measure the concentrations of multiple target bioanalytes and a single bioanalyte repeatedly.

In some examples, a device includes a catheter insert elongated body defining a body lumen, the catheter insert elongated body being configured to be at least partially inserted to a catheter lumen defined by a catheter without covering a first fluid opening of the catheter and to form a fluidically tight coupling with the catheter, and one or more sensors positioned on the elongated body. At least one of the one or more sensors are configured to sense a substance of interest. The catheter insert elongated body includes a material that is a substantially non-permeable to the substance of interest.

A method of analyzing fluid collected from a wound site, the method comprising the steps of: (a) providing a pump unit comprising: one or more pumps, one or more fluid collectors, and one or more drainage structures each in communication with an exit site of the wound site to draw the fluid through the one or more drainage structures into the pump unit and create a negative pressure at the exit site to remove and transport the fluid from the exit site and into the one or more fluid collectors, wherein the pump unit is configured to create a negative pressure, wherein the fluid removal from the exit site is provided at a controlled and measured rate; b) collecting the fluid within the one or more fluid collectors; c) removing the one or more fluid collectors; e) capping the one or more fluid collectors with a cap; and d) analyzing the collected fluid of step “b” once the fluid connectors are removed in step “c”.

A test strip for sampling a bodily fluid may include multiple layers of a substrate material, an adhesive between at least some of the multiple layers, and a microfluidic channel formed between at least some of the multiple layers. The test strip may further include multiple electrodes on one of the multiple layers, positioned and partially exposed within the microfluidic channel, an additional material positioned at or near an entrance to the microfluidic channel, to selectively limit the flow of at least one of bubbles or debris into the microfluidic channel, and at least one exit port in at least one of the multiple layers to allow for release of pressure from the test strip. In some embodiments, the test strip is a saliva analysis test strip. In some embodiments, the test strip includes multiple exit ports to prevent blockage of sample flow.

A health monitoring urinalysis system that monitors several health indicators from human urine is provided. The system includes a temperature sensor and several electrochemical sensors that are installed in a urine collection basin, such as, a toilet or a urinal and may automatically collect urine information after each use. The system collects data during the routine and normal use of a urine collection basin. The system includes a control and measurement unit that may be installed outside the urine collection basin. The control and measurement unit receives sensor measurements and transmits the measurements to one or more remote electronic devices. The remote electronic devices and/or the processor of the control and measurement unit perform data analysis, provide diagnostic, and generate health alerts. The system performs recurrent health monitoring after the urine collection basin is used and may detect abnormal conditions at early stages, in addition to a routine urine test.
