The present invention is a small device containing at least the following elements: a MEMS microphone, an amplifier, a microprocessor with audio frequency filters, a wireless transmitter, and a battery. The device may be placed behind the ear of the user on a bony protrusion of the skull and may be held in place by a variety of known methods, including adhesives such as spirit gum, adhesive tape, and a small circular adhesive bandage. The MEMS microphone detects sounds transmitted through the skull by bone conductance and the microprocessor analyzes the sounds to determine whether they are associated with a bruxism event. If so, data associated with the sounds are sent via the wireless transmitter to an external device. The data may be stored for later review by the user or medical professional, or may trigger a response such as an auditory or vibratory alarm.

Apparatus and systems that improve or enhance a user's visual experience are provided. The apparatus or system includes an intraocular implant which incorporates a processor, a sensor, and an effector. The apparatus or system is responsive to commands provided by a user, for example spoken commands, gestures, and imagery. All or part of the apparatus or system can be located within the user's eye. Some embodiments include a display, which can provide an enhanced image and/or information related to the apparatus or system.

An apparatus includes a catheter, an introducer, and an actuator. A distal end portion of the introducer is configured to be coupled to a peripheral intravenous line. The introducer defines an inner volume having a first portion that defines an axis parallel to and offset from an axis defined by a second portion. A first portion of the actuator is movably disposed in the first portion of the inner volume. A second portion of the actuator is movably disposed in the second portion of the inner volume and coupled to the catheter movably disposed in the second portion of the inner volume. The actuator moves the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which at least a portion of the catheter is disposed within the peripheral intravenous line.

A data processing system is configured to identify treatment responsive to a health risk determined from feature data provided by one or more networked data sources. A classification engine generates a feature vector based on a natural language processing (NLP) of input data representing words provided by a user. Features of the feature vector represent health risk factors. Machine learning logic classifies the features to generate a classification metric indicating whether the features are indicative of health risks or not indicative of health risks. A prediction value is generated indicating a likelihood of each health risk factor for the patient. The patient can be diagnosed with a health condition or disease based on the identified health risks.

This invention relates to a medical device (20, 40, 60) for use in aiding the successful placement of a needle tip in a blood vessel. The medical device comprises a resiliently deformable collapsible body (21) defining a pressure chamber therein. The body further comprises a port (29) for engagement of a hub of a needle, the port defining a fluid passageway from the exterior of the body to the interior of the pressure chamber. The device further comprises means to generate an audible noise (31, 41) upon expansion of the collapsible body from a collapsed configuration to an expanded configuration. In this way, as the tip of the needle enters the lumen of the blood vessel, the collapsible body is configured to transition from a contracted to an expanded configuration, thereby causing the auditory cue. This auditory cue indicates to the medical professional that the tip of the needle is in the lumen of the blood vessel.

A blood draw device for delivery of a probe into a patient's vascular system, the blood draw device including an introducer body having a proximal end and a distal end, and an actuator. The actuator is displaceable along at least a portion of the introducer body, and the actuator is operably coupled to the probe to advance and retract the probe based on direction of displacement of the actuator. The blood draw device also includes an advancement stop member, wherein the advancement stop member is displaceable along at least a portion of the introducer body and is configured to selectively limit travel of the actuator along the introducer body.

A medical device includes a catheter having proximal and distal ends, and defining a lumen, an introducer having proximal and distal ends, and defining an inner volume configured to movably receive the catheter. The distal end of the introducer has a lock configured to couple the introducer to an intravenous line, the introducer having a flexible member arranged within the inner volume configured to limit deflection of the catheter as the catheter is moved within the introducer, and an actuator movably coupled to the introducer. The actuator has a first portion disposed outside the introducer and a second portion disposed in the inner volume of the introducer and coupled to the catheter. The actuator configured to move relative to the introducer to move the catheter between first and second positions, such that the first portion is disposed within the intravenous line when the introducer is coupled to the intravenous line.

An applicator for applying a microneedle patch to a skin of a subject, comprising a base having a skin-side end and a holder for holding the microneedle patch. Two or more contact parts are movable over the skin and away from each other to stretch the skin. The applicator further comprising an interface for an actuator. The actuator actuates a movement of the microneedle patch relative to the skin-side end to penetrate at least into the stratum corneum of the epidermis of the skin with the microneedle. A microneedle patch comprising a skin-adhesive surface for attaching the patch to the skin of a subject. The patch has one or more projecting microneedles. A stiffening body stiffens the patch in at least a parallel direction parallel to the skin-adhesive surface in a region of the skin-adhesive surface which includes the microneedle.

Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.
