The present invention is directed to an electrically conductive substrate (1002) coated with one or more herbal essences wherein the substrate may be a flat sheet of conductive metal or polymer. The coating (1120) may be present as separate sections on the substrate and multiple conductor contacts may be present on the substrate or may be separate components. Multiple coated substrates may be stacked together to form a cartridge for use in an herbal essence delivery device.

A benefit agent delivery system whereby benefit agents can be delivered on demand and/or a variety of different benefit agents at different concentrations can be delivered from the same system. The benefit agent delivery system includes a microcell layer comprising a plurality of microcells, wherein the microcells are filled with a carrier and a benefit agent. The microcells include an opening, wherein the opening is spanned by a sealing layer comprising a polymer and metallic material. Application of an electric field across the microcell layer and the sealing layer results in the migration of the metallic material from the sealing layer and the creation of a porous sealing layer, allowing the benefit agent to be released from the benefit agent delivery system.

A unilateral-driven drug infusion device includes a drug storage unit, a screw, at least one driving unit, a power unit, a reset unit and an infusion tube. The drug storage unit includes a drug outlet. The screw is connected to a piston and a driving wheel provided with wheel teeth, respectively, wherein the driving wheel drives the screw to move by rotation, and push the piston provided in the drug storage unit to move forward. The driving unit cooperates with the driving wheel, wherein the driving unit includes at least one driving portion. The power unit and the reset unit are connected to the driving unit. The infusion tube includes a connection end and a subcutaneous end, and the connection end is communicated with the drug outlet and the subcutaneous end.

A wall (39) of a catheter (38) (a) includes a braided portion (41) having an outer surface (45), an inner surface (47), and a braided interior (53) between the outer and inner surfaces (45, 47), and (b) is shaped to define first and second longitudinally-running channels (27a, 27b) therethrough. A distal portion of the catheter (38) is shaped to define first and second lateral openings (26a, 26b). An angle between (a) a first line (76) running between the first and second lateral openings (26a, 26b), and (b) a second line (78) that is parallel to a central longitudinal axis of the catheter (38) when the catheter (38) is straight, is between 30 and 150 degrees. A flexible longitudinal member (14) passes from a proximal portion of the catheter (38) to the distal portion via the first channel (27a), out of the first channel (27a) via the first lateral opening (26a), into the second channel (27b) via the second lateral opening (26b), and from the distal portion to the proximal portion via the second channel (27b).

A pump interface tubing for use in a peristaltic pump includes a tubular core having an outer surface and a treatment on the outer surface. The treatment reduces static charge buildup on the tubular core during operation of the peristaltic pump, and thereby reduces the noise signal that might otherwise undesirably couple to a signal of interest. Treatments include nitrile layers, heat shrink layers, cotton fiber layers, and anti-static sprays.

A personal vapor inhaling unit including a microprocessor, memory, and a wireless communication interface is disclosed. An application may control aspects of the personal vapor via the wireless interface. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

Ingestible devices with a relatively large payload volume or sample volume, as well as related components, systems and methods, are disclosed.

Provided is a Dry Powder Inhaler (DPI) arrangement comprising a DPI arranged in fluid communication with a spacer device (110) comprising a bag (112) and a body (118) including inlet (114) and opposed outlet (116), the inlet (114) and opposed outlet (116) being provided on, and integral with, the body (118). The body (118) and bag (112) combine to form chamber (120) for operatively receiving vaporised dry powder medication. The inlet (114) and outlet (116) each are in the form of a port that is in fluid flow communication with the chamber (120). The inlet (114) and outlet (116) define, and are separated by, a broad V-formation formed as part of the body (118). The body (118) further includes an elliptical lower perimeter (118.1) defining flange (118.2), for demountably receiving bag (112).

The invention discloses a miniature closed-loop artificial pancreas system, comprising: infusion unit configured to deliver drugs; program unit comprising input end and output end, and the input end comprises a plurality of electrically connective regions for receiving signals of analyte data in the body fluid, after the output end is electrically connected to the infusion unit, according to the received signals of analyte data in the body fluid, the program unit controls whether the infusion unit delivers drugs; an infusion cannula with conductive area, the infusion cannula is the drug infusion channel; and a plurality of electrodes for detecting analyte data in body fluid, the electrode comprising conductive-area electrode and cannula-wall electrode, and one or more cannula-wall electrodes being located on/in the wall of the infusion cannula. It takes only one insertion to perform both analyte detection and drug infusion.

A drug delivery container and a nebulizer device are provided. The drug delivery container includes a body unit, a base unit, and an atomizing unit. The body unit includes a chamber element, the chamber element includes an accommodating space, an opening, and a through hole, and the accommodating space is communicated with both the opening and the through hole.
