  • Patent number: 10478572
    Abstract: A dry powder inhaler for pulmonary or nasal use, comprising at least an inhaler body 801 and a cartridge 803 with at least one powder compartment 805 including one dose of a drug. The body has an opening 804 shaped for receiving the cartridge 803 and the means to allow a controlled sliding movement of the cartridge 803 relative to the body 801 after mounting. The cartridge powder compartment 805 comprises at least two inlets or slits 806, 809, at least one of which is a side inlet 809, for the admission of air, and a compartment outlet 807 to allow filling and fluid communication with an inhalation channel 808 provided in the body 801.

  • Publication number: 20190143033
    Abstract: Systems and methods for automatic flow termination for fluid delivery, including a housing configured for coupling a fluid delivery tube to a needle configured for subcutaneous delivery of fluid within a tissue of a patient and a spring-loaded activation mechanism having a first orientation corresponding to a condition where the housing is disposed substantially adjacent to the tissue and the needle lodged within the tissue and a second orientation corresponding to a condition where the housing is disposed away from the tissue or the needle being dislodged from the tissue. A flow termination mechanism is coupled to the activation mechanism and having an open configuration allowing flow from the fluid delivery tube to the needle when the activation mechanism is in the first orientation and a closed configuration substantially terminating flow from the fluid delivery tube to the needle when the activation mechanism is in the second orientation.

  • Patent number: 9488059
    Abstract: A fan blade includes an airfoil and a dovetail at a radially inner end of the airfoil. The dovetail extends between first and second axial ends, and has outer circumferential faces. The dovetail is formed of relatively rigid composite material. Compliant material is placed on each outer circumferential face of the dovetail. The compliant material is less rigid than the composite material for forming the dovetail. In a second embodiment, the compliant layer may be positioned within the disk slots in a disk, such that the compliant layer will come in contact with circumferentially outer faces of the dovetail.

  • Publication number: 20050054253
    Abstract: The invention is directed to an absorbent article, comprising: a topsheet; a backsheet; an airlaid mixture material disposed between the topsheet and the backsheet. In one aspect of the invention, the airlaid mixture material includes a) cellulosic fibers, and b) thermoplastic fibers having a surface treated with a surfactant including a phosphate ester, a sulfate ester, or a derivative thereof. The cellulosic fibers and the thermoplastic fibers are bonded together to form a thermally bonded airlaid matrix which preferably has dry density of from about 0.04 to about 0.11 g/cc under pressure of 20 gf/cm2.

  • Patent number: 5017490
    Abstract: Method and apparatus for in vitro culture of cells in culture medium to produce a viable cell mass of cell number greater than the initial cell number, wherein a cell mass of particular cell number is cultured in a first oxygen-permeable culture sub-compartment to an increased cell number, and then aseptically transferred directly from the first sub-compartment to a next serial culture sub-compartment providing additional medium and/or culture space for further growth and reproduction to produce a viable cell mass of still higher cell number. Continued transfers are made, if necessary, to successive serial culture sub-compartment until a viable cell mass of desired cell number is attained, particularly one useful for seeding of a production-scale culture system.
