  • Patent number: 11547628
    Abstract: Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of a user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The source of saline solution is disposed relative to the device to provide gravitational inducement of the saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and a relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of the user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

  • Patent number: 11433228
    Abstract: This invention concerns improved single use caps or covers for vascular access devices such as needlefree connectors that are used, for example, in intravenous administration sets and extension sets. Removal of a single use cap or cover according to the invention from a vascular access device destroys the cap such that the cap cannot be reused. Said single use caps or covers will help ensure compliance with infection prevention protocols in healthcare settings, which will assist in reducing incidences of healthcare-associated infections (HAIs), particularly catheter-related blood stream infections. Assemblies and kits including said caps or covers, for example, IV administration and extension sets that include one or more needlefree connectors, as well as methods for using said caps or covers, are also described.

  • Patent number: 11406762
    Abstract: A drug delivery device comprising a housing body; a piston rod configured to rotate in a rotational direction during dose dispensing under a driving force; and a threaded insert, wherein the piston rod is in threaded engagement with the threaded insert such that during the dose dispensing. the piston rod displaces axially in a distal direction relative to the threaded insert for displacement of a cartridge hung. The threaded insert is movable relative to a stop provided in the housing body and a spring is provided to bias the threaded insert against the stop so that the rotation of the piston rod causes the threaded insert to move away from the stop in response to reaction forces, induced by the cartridge bung into the threaded insert, acting on the piston rod in a proximal direction when the reaction forces exceed a biasing force of the spring.
