A fluid sampling device and a method is provided for collecting body fluid samples such as blood without the intervention of medically trained personnel. The body fluid sampling device having a sample containment chamber made of a material having a thermal inertia permitting the maintenance of sample temperature over a known period of time. Optionally an isolating cover or sleeve may slide in place by a mechanism triggered by thermal contraction of an element after the device has reached a sufficiently low temperature in a patients refrigerator. Associated methods are provided to ensure hermetic transport of the collected body fluid sample to an analysis lab. Also disclosed is a device and app combination for drug or vaccine injection, the app including means to allow for verification of the patient's ID and/or the particular device used. The device my be equipped with geo-localization and long-range communication capabilities.

A system and method for measuring the percent fill of a blood sampling capillary includes a chamber for receiving a sample capillary containing a blood sample, an illuminator arranged to illuminate the sample capillary, an imaging lens aligned with the chamber and the sample capillary, an image sensor aligned with the imaging lens wherein the image sensor receives an image of the blood in the sample capillary from the imaging lens and converts the image to image data, a micro-controller circuit electrically coupled to the image sensor, and at least one of a host computer or a user interface electrically coupled to the micro-controller unit where the micro-controller circuit processes the image data into a percent fill result where the percent fill result is passed to the at least one of the host computer or the user interface.

A blood vessel visualization apparatus, a blood vessel puncture system, and an observation window member include: light sources that irradiate with near infrared light a visualization target site; an observation window that contains a wavelength conversion material for converting the near infrared light into visible light; a frame member that holds the observation window; and support members that support the frame member apart from the visualization target site. The observation window visualizes an image of near infrared light radiated from the light sources and reflected by the visualization target site.

A device for communicating a driving ability level of a user, the device comprising at least a processor, a memory, and a wireless transceiver. The device is configured to: receive a communication from a medical device, wherein the communication comprises information relating to a condition of the medical device; and send a communication to a vehicle. The information relating to a condition of the medical device is processed in order to determine a driving ability level of the user by the assignment of a category selected from a group comprising a first category and a second category.

A medical device with a capacitive sensing function includes a medical body having a syringe and a sensing circuit having an electrode, a protective film adhered to the medical body and including a plastic film, an electrode provided on the plastic film and opposite from the electrode of the medical body, and a capacitive sensor formed by the electrode of the medical body and the electrode of the protective film and being a part of the sensing circuit, wherein a capacitance value of the capacitive sensor changed under the condition of removing the protective film from the medical body, the sensing circuit being configured to detect the capacitance value and trigger corresponding function of the medical body.

Device for arterial puncture assistance. In an embodiment, the device comprises an upper component, lower component, and coupling mechanism that couples the lower component to the upper component. The upper component may comprise a platform configured to support a syringe. The lower component may comprise one or more finger holes, wherein each of the one or more finger holes is configured to receive a human finger therethrough, so as to enable contemporaneous stabilization of the lower component on the human finger and palpation of an arterial pulse by the human finger during an arterial puncture.

Described here are devices, systems, and methods for analyte measurement. The analyte measurement devices and systems may be configured to produce a prompt that may convey information, instructions and/or encouragement to a user. In some variations, analyte measurement devices may be configured to change a prompt based on the replacement or addition of components of/to the device. In some instances, a prompt may be an auditory prompt and/or a visual prompt. In some variations, a system may comprise an analyte measurement device comprising a housing, a speaker, and a control unit. The housing may comprise a releasable housing portion comprising an identifier that is associated with a prompt. In some variations, a system may comprise an analyte measurement device and a skin that may releasably attach to the analyte measurement device and may comprise an identifier that is associated with a prompt.

A vein stabilizer device for venipuncture procedures is provided. The vein stabilizer device is embodied in an elongated body providing an external stabilizer tip protruding from a distal end of the body. The stabilizer tip may be defined by a supratip break, an infratip break, and two lateral breaks. Surface area of the breaks are dimensioned and adapted to engage the skin of a patient so as to stabilize a vein therein. The elongated body has a cavity for slidably receiving a finger of a user in such a way that the user can selectively apply pressure through a chosen break surface.
