Abstract: A feeding device includes a fluid reservoir and a nipple configured to be attached to the fluid reservoir. The nipple includes a base portion and a teat portion, where the base portion and the teat portion together define an interior space of the nipple. The nipple also includes a removable flow valve configured to be positioned within the interior space of the nipple and an internal cavity between the removable flow valve and a wall of the nipple. The removable flow valve includes a central opening and at least one valve protrusion extending from a surface of the flow valve into the internal cavity. The removable flow valve is configured to adjust a flow rate of a fluid from the fluid reservoir into the internal cavity.

Abstract: Powered toothbrush systems that provide improved bristle positioning and bristle contact with tooth surfaces that reduce the time and effort required for effective brushing. Some embodiments use alternating or oscillating pneumatic pressure and suction to move a toothbrush head. Various configuration of the brush head provide different areas of coverage ranging from individual tooth to quarter mouth (U-cross section), to half (U-cross section or H-cross section) or whole mouth (U-cross section or H-cross section) coverage. Some embodiments include flexible fingers and/or bladders to keep the bristle tips properly engaged with the teeth and gums, providing bristle contact over a wide variety of malocclusion. The shape of the brush heads adapts to conform closely to the shape of the user's dental tray and to any malocclusion that may be present. The powered toothbrush automatically generates motion of the brush head that simulates the Modified Bass Method of brushing.

Abstract: Apparatus and assemblies for automated sterile collection of urine and other biomaterials for medical testing, law enforcement testing, etc. Individual sample collection cartridges include an inflatable collection conduit and an inflatable collection vessel. The collection vessel can be sealed in multiple locations in a chronologically sequential manner to segregate an initial or “dirty” portion of a urine stream.

Abstract: A method of identifying the presence of an analyte may include providing an in vitro test device and a test swab; obtaining a sample using the test swab; transitioning the locking member from the first configuration to the second configuration; advancing the plunger into the housing to pierce the one or more reagent pouches in the reagent region to cause reagent therein to be released and mix; inserting the test swab with obtained sample into the interior of the plunger; rotating the in vitro test device and disposing it on its plunger base; and determining whether the analyte is present. The in vitro test device may include a plunger, a housing, one or more reagent pouches disposed in the housing, a lateral flow test strip, and a locking member having configurations that either allow or prevent reagent in the one or more reagent pouches from being released.
