The present disclosure is directed to wearable or insertable devices that allow for ongoing sampling and analysis of biomarkers and self-cleaning. In various embodiments, an apparatus may include a base (102) defining at least one reservoir (104), and at least one microneedle (106, 306, 406, 506, 606, 706, 806, 906) extending from the base. The at least one microneedle may define an inner lumen (409, 509, 609, 709, 809, 909) that fluidly couples the at least one reservoir with tissue of the patient. A mechanically responsive material (670, 770, 870) on an inner surface of the at least one microneedle defining the inner lumen may be reactive to various stimuli to undergo various mechanical responses, such as one mechanical response that purges fluid from the inner lumen of the at least one microneedle and another mechanical response that draws fluid into the inner lumen of the at least one microneedle.

A health monitoring system comprises a housing, a test strip assembly, a lancet, a transparent cover, and a monitor. The test strip assembly is configured to detect concentration of the sample of the blood, using lancet. It also has multiple ways to test blood like a laser-based system and a wireless based blood measuring system. Further, it has a heart rate monitor system, blood pressure and weight measuring rechargeable straps, wireless systems for information exchange with other devices, two way communication systems, a flash light, a removable X-Ray lens system, an auto created individual profile system based on a multi-factor authentication system that is capable of automatic grouping of all test results or any data created by a user, auto retrieving from a remote computer server and auto installing on a device based on its limitations through onboard multi-factor authentications systems.

Bodily fluid withdrawing devices including electronics, and associated systems and methods, are disclosed. In some embodiments, the devices include a housing containing a bodily fluid withdrawing feature, an actuator movable relative to the housing, and one or more electronic component(s). The electronic component(s) can be configured to transition from an inactive state to an active state when the device is actuated and a circuit of the device is closed. Upon transitioning to the active state, the electronic component(s) can be configured to wirelessly transmit information and/or receive information from an external recipient. In some embodiments, the devices disclosed herein can comprise part of an interconnected system including one or more communication devices.

Disclosed are methods, systems, devices and articles, including a method for adaptive wireless communication transmissions between units of an ambulatory portable medical device. The method includes obtaining data relating to wireless transmissions between the units of the medical device, and setting one or more attributes of wireless transmission of one or more messages between the units of the medical device based, at least in part, on the obtained data.

Compact devices are provided to measure hematocrit of a blood sample. These devices include first and second chambers that receive respective portions of a blood sample via respective filters. The material of the filters prevents passage of red blood cells while permitting passage of blood plasma. One of the filters has one or more holes to permit the passage of whole blood. Thus, when an example device is presented with a sample of blood, one of the chambers contains whole blood and the other contains blood from which the red blood cells have been filtered. Electrodes in each of the chambers can then be used to detect the impedances of the whole blood and the filtered blood, and the detected impedances can be used to determine a hematocrit of the sample of blood.

A fluid handling module that is removably engageable with a bodily fluid analyzer is provided. The module may comprise a fluid handling element, and a fluid component separator that is accessible via the fluid handling element and configured to separate at least one component of a bodily fluid transported to the fluid component separator. The fluid handling element may have at least one control element interface.

Disclosed is an apparatus for analyzing the composition of bodily fluid. The apparatus can include a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient and a pump unit in operative engagement with the fluid handling network. The pump unit can have an infusion mode, in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode, in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus can include a spectroscopic analyzer positioned to analyze at least a portion of the sample; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain measurements of two or more properties of the sample.

This invention is in the field of medical devices. Specifically, the present invention provides portable medical devices that allow real-time detection of analytes from a biological fluid. The methods and devices are particularly useful for providing point-of-care testing for a variety of medical applications.

The present disclosure is directed to enhanced sampling of bioanalytes from bodily fluids using wearable and/or insertable devices. In some embodiments, an apparatus (100, 500, 600) for sampling bioanalyte(s) in tissue (107, 507, 607) may include: a base (102, 502, 602) having conduit(s) adapted to receive fluid extracted from the tissue; microneedles (106, 306, 506, 606) fluidly coupled with the conduit(s) and adapted to be pierced into the tissue; a plurality of individually-controllable energy emitters (112, 114, 350, 612, 614); and logic (90) operably coupled with the plurality of individually-controllable energy-emitters. The logic may be adapted to operate a subset of the plurality of individually-controllable energy emitters to apply energy at a first subset of the microneedles to induce bioanalyte flow through tissue towards the first subset or a second subset of the microneedles, or through the first subset or a second subset of the microneedles.

An automated computer operating software system for automatically generating user profiles is disclosed. The system is configured to automatically creates a profile or a number profiles based on biometric methods but also stores the profile(s) information along with an associated device(s) information and user generated data locally and remotely through various hardware modules and can also retrieve this information to any other device based on biometric authentication on the other device and auto adjust the operating parameters according to that other device and its operational parameters and again continue this same kind of auto creating, backing up and retrieving of both the profile of the user and device as well in a continuous loop of infinite number devices and user profiles.
