摘要： A medical device position notification system including a medical device and at least one sensor associated with the medical device, a processor, and a display device. The medical device is configured to be inserted into an orifice of the patient. The sensor measures information related to the position of the medical device in the patient's body, and communicates the information with the processor in real-time. The display device is coupled to the processor and is configured to display a tracing path of the position of the medical device in real-time. The display device is further configured to display a notification of the position of the medical device within the patient's body, such as a notification alert that the medical device has deviated from a predetermined path.

摘要： A tubing assembly (14) for use in conjunction with electronic catheter guidance systems is provided and includes a catheter (50) and a steering apparatus (79). The steering apparatus (79) includes an electrical connection (84) and a sheath (80). The sheath (80) includes an electroactive polymer layer (82), and the sheath's proximal end (85) is coupled to the distal end of the electrical connection (84), where the steering apparatus (79) is located within the lumen of the catheter (50). Activation of the electroactive polymer layer (82) results in a change in dimension of the sheath (80), which initiates a change in a direction in which the catheter (50) travels within a patient's body to assist in accurate placement of the catheter (50) at a desired location. A catheter guidance system and a method for steering a catheter during its placement inside a body are also provided.

摘要： Enteral tubes, tube tip detection systems, and methods for detecting tube misplacement are provided. For example, a tube tip detection system comprises an enteral tube having a tip and a first light disposed at the tip that is illuminated as the enteral tube is inserted into a patient to indicate to a user of the system whether the tip is misplaced in the patient's airway. Similarly, enteral tubes are provided that comprise a tip, a length, and a light that is continuously illuminated as the enteral tube is inserted into a patient. Methods for detecting a tube misplacement in a patient's airway include embedding a light into an enteral tube, inserting the enteral tube into the patient through the patient's nose or mouth, and monitoring a location of the light as the enteral tube is inserted into the patient to determine if the tube is traveling into the patient's airway.

摘要： A method of forming an electronic part comprising a metal component is provided. The method includes obtaining an unverified mineral sample from a mine site, analyzing the unverified mineral sample via quantitative mineralogical analysis and comparing data collected during the quantitative mineralogical analysis for the sample to data in a database that corresponds to quantitative mineralogical analysis collected for verified mineral samples sourced from one or more mine sites from the conflict-free geographic region to determine if the unverified mineral sample is sourced from one or more mine sites from the conflict-free geographic region. If it is determined that the unverified mineral sample is sourced from one or more mine sites from the conflict-free geographic region, the method then involves converting the unverified sample into the metal component. The electronic part can be a capacitor, medical device, filter, inductor, active electrode, antenna, sensor, or battery.

摘要： Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly including a gasket and a sheet of filter material. The sealing assembly seals a lid to a seal rim of a base. The gasket has an upper surface, outer edge, and inner edge. The upper surface of the gasket comprises a first row of alternating protrusions and indentations and a second row of alternating protrusions and indentations that define a channel therebetween. The sheet of filter material extends from an inner edge of the gasket. The gasket completely surrounds the sheet of filter material, wherein the indentations and channel facilitate delivery of a sterilization agent through the filter material. A sterilization assembly including a lid having a plurality of protrusions in its upper surface in conjunction with a gasket having a smooth upper surface is also provided.

摘要： An absorbent stoma pad for encapsulating an external bolster of a feeding tube is provided. The stoma pad includes an upper layer, base layer, absorbent material, and cavity. The upper layer, which includes an upper surface and a lower surface, contains a centrally located opening with respect to a periphery of the upper layer, wherein the opening is configured to receive a tube portion of the feeding tube. The base layer, which includes an upper surface and a lower surface, contains a centrally located opening with respect to a periphery of the base layer, wherein the opening is also configured to receive the tube portion of the feeding tube. Meanwhile, the absorbent material is disposed adjacent the upper layer's lower surface. Further, the cavity permits airflow between the absorbent layer and the base layer when the external bolster is encapsulated by the stoma pad and positioned within the cavity.

摘要： Articles and methods for non-invasively treating peripheral neuropathy via transcutaneous electrical stimulation of target nerve tissue are described. An exemplary article includes a support on which an electrode pair is positioned; a controller attached to the electrode pair via one or more leads; and a power supply connected to the controller. The article delivers electrical stimulation to the target nerve tissue via the electrode pair at a level sufficient to initiate vasodilation of vasculature within or adjacent the tissue. Meanwhile, the method includes positioning at least one electrode pair adjacent an area of skin overlying or in close proximity to the target nerve tissue and delivering electrical stimulation to the tissue via the electrode pair. The electrical stimulation is delivered at a level sufficient to initiate vasodilation of vasculature within or adjacent the tissue. An implantable system and method for treating peripheral neuropathy via percutaneous electrical stimulation are also described.

摘要： A product and method for reducing tensile strength loss associated with sterilization of the product by ionizing radiation sterilization methods is provided. The method includes providing a package that includes a layer having an oxygen transmission rate equal to or less than about 10 cubic centimeters of oxygen per 100 inches squared per 24 hours; providing a product in the package's interior; applying a vacuum to the exterior of the package in a controlled atmosphere until a vacuum pressure equal to or less than about 250 millibars is achieved; flushing the interior of the package with an inert gas until an inert gas flush pressure equal to or less than about 750 millibars is achieved; sealing the package; releasing the vacuum applied in the controlled atmosphere; and sterilizing the package/product with radiation. The resulting product has a reduction in its tensile strength of less than about 18.5% after sterilization.

摘要： A multi-layered face mask (100) coated with discontinuous patterns of phase change material (300) are incorporated into the face mask (100) construction to provide for cooling of the microclimate in the dead space of the face mask (100). Optimized cooling is achieved by strategic placement of layers coated with a phase change material (300) within the mask (100) construction and the amount and density of the phase change material (300) in contact with the temperature sensitive areas of the face, as well as areas experiencing the maximum amount of flux from exhaled breath. The shape of the mask (100) can also be adjusted to increase skin contact with the phase change material (300) and decrease dead space volume, which reduces the volume of warm exhaled air and can provide sufficient cooling with less phase change material (300). The discontinuous patterns of phase change material (300) also provide inter-layer spacing between the layers of the mask (100), which can improve splash resistance.
摘要翻译：将涂有相变材料（300）的不连续图案的多层面罩（100）结合到面罩（100）结构中，以提供冷却空间中的微气候的冷却面罩（100）。优化的冷却通过在面罩（100）结构内以相变材料（300）涂覆的层的有策略的放置以及与面的温度敏感区域接触的相变材料（300）的量和密度来实现，如以及呼出气量最大的区域。还可以调节面罩（100）的形状以增加与相变材料（300）的皮肤接触并减小无效空间体积，这减少了热呼出空气的体积并且可以用较少的相变材料（300 ）。相变材料（300）的不连续图案还提供掩模（100）的层之间的层间间隔，这可以提高耐溅射性。
