Systems and methods for autonomous intravenous needle insertion are disclosed herein. In an embodiment, a system for autonomous intravenous insertion include a robot arm, one or more sensors pivotally attached to the robot arm for gathering information about potential insertion sites in a subject arm, a medical device pivotally attached to the robot arm, and a controller in communication with the sensors and the robot arm, wherein the controller receives the information from the sensors about potential insertion sites, and the controller selects a target insertion site and directs the robot arm to insert the medical device into the target insertion site.

A device is provided for the detection of an analyte in a sample. The device includes at least one capillary, at least one measurement chamber and at least one cantilever pair. The capillary is configured to take a sample and to feed it to the measurement chamber that collects the sample and provides it to the cantilever pair. The cantilever pair includes a reference cantilever and a test cantilever. The test cantilever selectively uptakes the analyte from the sample and the reference cantilever selectively non-uptakes the analyte from the sample. The respective uptakes cause a relative deformation and/or a relative change in the surface tension of the test cantilever relative to the reference cantilever. The relative deformation and/or the relative change in surface tension of the test cantilever and the reference cantilever results in detection of the analyte.

A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing, to determine venous oxygen saturation is described. The system uses averaging of similar pulses based on Prior (or n1) R-to-R pulse wave duration, and current (or n) R-to-R pulse wave duration for evaluation of the metabolic reserve and/or stress of the patient.

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

A needle assembly for sampling fluid from a patient including a needle guard, an insertion needle, and a needle housing. The distal end of the needle guard includes a nose portion and a flexible nose extension defining a fluid collection reservoir. The proximal end of the needle guard includes a push feature. The insertion needle has a sharpened distal tip, a proximal needle end and a shaft defining a lumen extending therebetween. The needle housing is operably coupled to the proximal needle end and is slideably coupled to the needle guard. The needle housing includes a flash chamber including a wall defining a cavity. The cavity is in fluid communication with the lumen of the insertion needle and is sealed at one end by a gas permeable flash plug. The push feature selectively engages the flash plug to divert captured bodily fluids to the fluid collection reservoir for sampling.

A test meter for receiving a test strip comprises: (a) a housing; (b) electronic circuitry disposed within the housing and (c) a strip port connector connected to the electronic circuitry and extending to an opening in the housing, said strip port connector connecting the electronic circuitry with a received test strip. The strip port connector contains a pair of top and bottom contacts, said top and bottom contacts having a proximal end and a distal end and a central contact portion, the top and bottom contacts of the pair are transversely aligned with one another; and the distal ends of the top and bottom contacts are separated or separable from one another by insertion of a test strip between the opposed contacts. The contacts and the meter are adapted to permit detection of faulty contacts and/or coding associated with an inserted test strip.

A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing to assess intra-arterial fluid volume is described. The system uses averaging of similar pulses based on prior (n?1; n minus 1) R-to-R pulse wave duration, and prior-prior (n?2; n minus 2) R-to-R pulse wave duration, to determine a patient's fluid status and whether it is below or above optimal intravascular hydration.

Embodiments described herein relate to an analyte monitoring device having a user interface with a display and a plurality of actuators. The display is configured to render a plurality of display screens, including a home screen and an alert screen. The home screen is divided into a plurality of simultaneously displayed panels, with a first panel displays a rate of change of continuously monitored analyte levels in interstitial fluid, a second panel simultaneously displays a current analyte level and an analyte trend indicator, and a third panel displays status information of a plurality of components of the device. When an alarm condition is detected, the display renders the alert screen in place of the home screen, the alert screen displaying information corresponding to the detected alarm condition. Furthermore, the actuators are configured to affect further output of the analyte monitoring device corresponding to the detected condition.

Techniques and examples pertaining to evaluating the health condition of a patient based on a diagnostic aspect of the patient are described. A method for evaluating the health condition may involve obtaining a measurement value of the diagnostic aspect of the patient by a diagnostics measurement device. The method may also involve calculating a relative ratio by a processor communicatively coupled to the diagnostics measurement device. The processor may calculate the relative ratio by dividing the measurement value by a standard average value of the diagnostic aspect. The method may also involve the processor calculating a health deviation by subtracting a baseline value from the relative ratio. The method may also involve the processor designating a health indicator based on the health deviation, such that the health indicator serves as an indication of the health condition of the patient.
