A method and device for self-testing a user's hearing. The disposable hearing test device includes a cardboard box containing a sound card with a sound processor, a speaker, and a battery. The sound processor includes a memory containing a digital audio rendition of each of N (e.g. 10) words, and N pressure-activated word buttons. The box has N word pressure regions, each of which when pressed activates a corresponding word button and causes the sound processor to play an audio version of one of the words. The user activates the battery and presses each of the pressure regions in turn, causing the words to be played at a pre-determined volume via the speaker. The user then counts the number of correctly recognized words and if the number is less than a threshold, the user is informed of a possible hearing problem.

An automatically locking safety device, e.g., for use in a blood collection procedure, can include a housing, first and second needle covers that are at least partly received in the housing, and a needle that is at least partly received in at least one of the first and second needle covers. The needle can include a proximal tip configured for placement into a patient and a distal tip configured for placement into a blood collection vial. In some embodiments, the first and second needle covers are biased by a biasing member. In some cases, one or both of the first and second needle covers can be locked to prevent axial movement thereof after the blood collection procedure. In certain embodiments, a distal end of the device is configured to connect with a medical connector, such as a needleless IV access device.

A training method is provided to train changing muscle contribution in a human subject while the human subject is performing a complex movement. Feedback is provided in a simple understandable fashion by one or more data points calculated based on electromyography signals obtained over e.g. a stance phase of a walking cycle. The training method showed a significantly increased training effect in subjects performing these complex movements where these subjects were able to change the muscle activation given a specific goal. The training could be setup of a single muscle or multiple muscles. The data point feedback could be a measure for the single muscle or some relative measure for the multiple muscles. The training method results in improved coordination strategies and could be useful for retraining purposes as well as intervention methods for musculoskeletal pathologies or movement disorders.

Needle protector assemblies including needle assemblies and needle protectors for housing used blood collection needles are disclosed. The needle protectors are single-piece protectors that include an open distal end for receiving a needle hub (with a needle mounted thereon). A retaining member locks the needle hub when the needle hub is substantially retracted. A stop engages the needle hub in a fully retracted position such that a needle post is completely contained within an interior chamber of the needle protectors. A viewing slot in the needle protectors is provided.

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.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes: a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising an inner member having a second opening, and an outer member at least partially surrounding the inner member and attached to the first opening; and at least one skin-penetration member configured and arranged to project within the second opening. Arrangements having alternatively constructed skin interface members are also described.

This disclosure relates to systems, media, and methods for providing near-instantaneous feedback from real-time motion sensor data. In an embodiment, the system may perform operations including loading at least one target motion trigger. Disclosed embodiments may receive real-time sensor data from the first motion sensor detachably fixed to a user. Additionally, disclosed embodiments may include calculating a motion profile based on the real-time sensor data, the motion profile describing a multi-dimensional representation of acceleration of a motion performed by the user. Disclosed embodiments may also include comparing the at least one target motion trigger to the calculated motion profile to determine if the motion performed by the user corresponds to the target motion. Further, disclose embodiments may include transmitting, based on the comparison, an instruction to provide an alert to a user.

Embodiments disclosed herein are generally directed to blood flash detection systems and methods thereof. Embodiments include an indicator device including a needle and needle hub, defining a lumen and in fluid communication with a medical line. The needle hub includes a marker, such as an RFID tag, with electrodes extending to the lumen. When a fluid flow, for example blood, enters the lumen, an electrical connection between the electrodes is bridged, completing the circuit and activating the marker. The marker can then be responsive to an interrogation signal, and can provide a response signal. The response signal can be detected and interpreted by a detection device that indicates to a user that the vasculature has been accessed without the user directly observing the insertion site or the device.

A method and system for actively monitoring anterior cruciate ligament (ACL) strain experienced at the knee joint during athletic activity or dynamic movement. Sensors are used in proximity of the knee joint to actively record parameters such as flexion angle and ground impact force at the knee joint. Sensor measurements are then inputted into a processing unit that will quantify a tibial shear force (TSF) value based on the sensor outputs and dynamically generate user feedback and/or warning signals when unsafe levels of TSF conducive to ACL injury are detected.

A monitor device for an ostomy system comprising an ostomy appliance with a base plate and a method of monitoring an ostomy appliance is disclosed. The monitor device comprises a processor configured to apply a processing scheme; memory; a first interface connected to the processor and the memory, the first interface configured for collecting ostomy data from the base plate coupled to the first interface; and a second interface connected to the processor, wherein to apply a processing scheme comprises: obtain first parameter data, second parameter data, and third parameter data based on the ostomy data; and determine an operating state of the base plate of the ostomy appliance based on the first parameter data, the second parameter data and the third parameter data, wherein the operating state is indicative of a degree of radial erosion of the base plate and/or acute leakage risk for the ostomy appliance, wherein the monitor device is configured to, in accordance with a determination that the operating state is a first operating state, transmit a first monitor signal comprising monitor data indicative of the first operating state of the base plate via the second interface; and in accordance with a determination that the operating state is a second operating state, transmit a second monitor signal comprising monitor data indicative of the second operating state of the base plate via the second interface.
