Abstract of the Disclosure

Systems and methods for integrating a continuous glucose sensor, including a receiver, a medicament delivery device, and optionally a single point glucose monitor are provided. Manual integrations provide for a physical association between the devices wherein a user (for example, patient or doctor) manually selects the amount, type, and/or time of delivery. Semi-automated integration of the devices includes integrations wherein an operable connection between the integrated components aids the user (for example, patient or doctor) in selecting, inputting, calculating, or validating the amount, type, or time of medicament delivery of glucose values, for example, by transmitting data to another component and thereby reducing the amount of user input required. Automated integration between the devices includes integrations wherein an operable connection between the integrated components provides for full control of the system without required user interaction.

An improved electronic evaporable substance delivery device delivers nicotine-containing vapor to a user from a smoking device. The smoking device comprises a case having therein a power source, microprocessor, heating element and nicotine-containing cartridge. Microprocessor-controlled heating of the heating element causes air passing thereover to be heated. Passage of the heated air in proximity of the cartridge causes boiling of cartridge contents, and the release of a nicotine-containing vapor. A user may ingest the nicotine-containing vapor via a mouthpiece located at a first end of the case.

An elongated access port has a needle-impenetrable housing enclosing a fluid reservoir. The housing includes a base having a floor with an upstanding encircling sidewall and a cap having a top wall with a depending encircling skirt. The skirt of the cap receives the sidewall of the base. An access aperture extends through the top wall of the cap to communicate with the fluid reservoir. The access aperture is encircled by a continuous rim having an elongated shape in the plane of the access aperture. The rim of the access aperture may be elliptical, oval, polygonal, or parabolic-ended. An elastomeric, needle-penetrable, generally planar septum is disposed in the access aperture with the periphery of the septum in sealing engagement with the rim of the access aperture. Prior to installation, the septum has a periphery with a cross section in the plane of the septum that is geometrically proportional to and larger than the shape of the access aperture. Installation causes the periphery of the septum to be displaced inwardly by the rim of the access aperture in a direction parallel to the plane of the septum. In view of the relative shapes of the rim of the access aperture and the periphery of the septum, this produces substantially uniform hydrostatic pressure in regions of the installed septum that are subjected in use of the access port to needle penetrations. Opposite faces of the periphery of the septum are urged toward each other between the cap of the housing and the top of the sidewall of the base of the housing.

An inhaler for multiple dosed administration of a pharmacological dry powder consists externally of a housing (100,150) and of a protective cap (950) which can be removed from a special mouthpiece (900) fitted on the housing. Arranged on the inside there are a slide rail (200), a dosing slide (300), a shutter (400), a carriage (500), a funnel arrangement (600), a counter device (700), a valve shield (800) and a valve guide (850). Removal of the protective cap (950) initiates the dosing, with a dose received in the dosing cavity (302) being transported to the mouth-piece (900) by means of the dosing slide (300). Only upon application of a defined minimum intensity of inhalation is the shutter (400) moved by the suctioned valve shield (800), as a result of which the dose is released for inhalation. Completed with an electronic module and a controllable nozzle, all inhalation-relevant data can be recorded and the flow conditions regulated.
