In one embodiment, a system may include a processor configured to receive a first image of a plurality of adjacent wounds near a form of colorized surface having colored reference elements, determine colors of the plurality of wounds, correct for local illumination conditions, receive a second image of the plurality of wounds near the form of colorized surface, to determine second colors of the plurality of wounds in the second image, match each of the plurality of wounds in the second image to a wound of the plurality of wounds in the first image, and determine an indicator of the healing progress for each of the plurality of wounds based on changes between the first image and the second image.

A method of determining a local cerebrospinal fluid flow rate. The method including the steps of positioning a distal end of the catheter in a flow of cerebrospinal fluid of the patient, the catheter including an infusion port and at least one temperature sensor positioned at a fixed distance from the infusion port, infusing a bolus of a temperature controlled fluid through the infusion port into the flow of cerebrospinal fluid, and monitoring a temperature sensed by the at least one temperature sensor, wherein a change in the temperature sensed by the at least one temperature sensor over time is representative of a local cerebrospinal fluid flow rate in proximity to the infusion port.

The invention relates to a device for accessing an area with restricted access or an area to which access is controlled, comprising a support, a sensor and access control stage, the support comprising a portion to be discarded and a portion to be retained, the sensor being borne by the portion to be discarded and being configured to measure at least one parameter of a subject's health, and to deliver a detection signal representative of the measurement of each health parameter, the access control stage being borne by the portion to be retained and being configured to store access information dependent on the detection signal delivered by the sensor, the portion to be retained being able to be mechanically separated from the portion to be discarded so as to form an access key allowing, depending on the access information, access or otherwise to the area with restricted access or to the area to which access is controlled.

Methods, systems, and devices are described herein for various embodiments of using a sample analysis system to analyze a sample of bodily fluid from a user to determine parameters associated with the user including states of hydration, dehydration, rehydration, electrolyte loss, wellness, recovery, and the like. In some embodiments, the methods disclosed can be implemented using a device worn by a user, and operatively coupled to a sample analysis system configured to collect a sample of bodily fluid, and measure and analyze the bodily fluid to determine a property of the bodily fluid and/or a physiological/wellness parameter (e.g., degree of hydration, electrolyte losses, perspiration rate, etc.) of the user.

A system for detecting presence of coronavirus in a subject, the system including a first pad for placing a first hand, the pad including a contact to measure conductance of the subject's body, a conductance meter connected to the contact, a second pad for placing a second hand, a source of electromagnetic radiation for irradiating the second pad.

A system for detecting presence of coronavirus in a subject, the system including a chip with a plurality of wires disposed on or in the chip, a conductance meter arranged to measure conductance between the wires, and biological material associated with the coronavirus disposed on or in the chip.

Related apparatus and methods are also described.

A portable system is provided for measuring a ketone, such as an acetone, in the breath or other bodily fluid of a user. The system includes a portable measurement device that analyzes fluid samples and generates corresponding ketone measurements. The portable measurement device communicates with an application which runs on a smartphone or other mobile device of the user. The application tracks, and generates graphs of, the ketone measurements, and may include various features for facilitating the analysis of the measurements.

In some examples, a diagnostic device includes a reusable part to receive a container of a fluid, the reusable part reusable for a plurality of diagnostic tests. The diagnostic device further includes a disposable part detachably attached to the reusable part and comprising a sample collector to collect a target sample of a living being. The diagnostic device further includes a tester comprising a fluid channel to transport the fluid to combine the fluid and the target sample to form a fluid combination, and to use the fluid combination to diagnose a condition of the target sample.

Embodiments disclose a device for testing biological specimen. The device includes a sample carrier and a detachable cover. The sample carrier includes a specimen holding area. The detachable cover is placed on top of the specimen holding area. The detachable cover includes a magnifying component configured to align with the specimen holding area. The focal length of the magnifying component is from 0.1 mm to 8.5 mm. The magnifying component has a linear magnification ratio of at least 1.

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.
