Abstract: A multi-port connector such as a closed intravenous (IV) access device with a y-port needle-free connector may be provided. The multi-port connector may include a main housing with a longitudinal axis, a needle free connector disposed along the longitudinal axis, and a y-port extending from a sidewall of the main housing at an angle that is non-parallel with the longitudinal axis. The needle-free connector may include a compressible sealing member that, when compressed opens a first fluid pathway from a first port, through a chamber within the housing, and to an output port. The y-port may be fluidly coupled to the chamber and the output port.

Abstract: An eyeglass lens for an optical imaging element for producing a virtual image of an initial image includes a main body and at least one complementary element mounted on the main body. The main body has a material with a first index of refraction n1. A viscous or solid intermediate layer is arranged between the complementary element and the main body at least in the region where the complementary element overlaps with a reflection section of the main body. The material of the viscous or solid intermediate layer has a second index of refraction n2 that satisfies the condition n2<n1 sin(?E). ?E is an angle of incidence of the light beams of the imaging beam path proceeding from the incoupling section and incident on the reflection section, selected such that at least 50% of the light beams of the imaging beam path have an angle of incidence of ?>?E.

Abstract: An optical system for generating a virtual image of a source image provided on an image generator includes a surface of an output coupling that is exposed to a light beam path that is surface-treated such that the light beam path is coupled out from an optical waveguide toward the eye from first partial regions of the surface of the output coupling. In second partial regions of the surface of the output coupling, said second partial regions being different from the first partial regions, said light beam path is coupled out from the optical waveguide toward the eye at most with reduced intensity, or not at all.

Abstract: A device to couple a vascular access device to a medical device may include a body, a spring, and a housing. The body may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The proximal end of the body may include a connector. The housing may be coupled to a proximal end of the spring and may enclose the connector. A distal end of the spring may be coupled to the body. The housing may include a flap, which may include an antimicrobial compound. When the housing is disposed in a proximal position, the flap may cover the connector, the antimicrobial compound may contact the connector, and the spring may be uncompressed. In response to movement of the housing from the proximal position to a distal position, the spring may be compressed and the flap may open.

Abstract: Needleless connectors are described herein. A needleless connector includes a body, a valve element at least partially disposed within the body, and a base.

Abstract: Needleless connectors are described. An example needleless connector includes a housing and a compressible valve. The housing may define an internal cavity and may include a body section having a first port and one or more internal contact tabs and a base section having a valve mount and a second port. The compressible valve may be disposed within at least a portion of the internal cavity and be movably retained within the housing. The compressible valve may include a flange portion for securing the compressible valve within the housing. A central longitudinal axis of the housing may be defined by a coaxial arrangement of the first and second port. The one or more internal contact tabs may be arranged to contact an outer side surface of the flange portion such that a radial force substantially orthogonal to the central longitudinal axis is provided for securement.

Abstract: A method for producing a freeform Fresnel surface having a number of Fresnel facets with a respective Fresnel segment surface and a trailing edge includes the production of the freeform Fresnel surface via machining processing of a starting body based on the construction data for the freeform Fresnel surface. With the aid of the circular cylinder casing surfaces and/or cone casing surfaces, the projection of the edges of the Fresnel facets on the x-y-plane represent circular paths for the creation of the construction data.

Abstract: A carousel configured to house a plurality of pump cartridges for a compounder system is provided. The carousel may include a plurality of cartridge pockets each having an extended portion that covers a portion of a cartridge and a bottom surface Shaving an extension with a recess. The bottom surface recess of each cartridge pocket may be shaped and sized to receive a needle housing of a pump cartridge in the cartridge pocket. A recess may be provided in the extended portion of each pocket that receives a protrusion that extends from a top surface of a backpack coupled to the pump cartridge to secure the pump cartridge in the cartridge pocket. The bottom surface recess may have an additional bottom surface that prevents actuation of the needle housing of the pump cartridge.

Abstract: A spectacle lens, which is manufactured by additive manufacturing, includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.

Abstract: A medical connector is described which is formed by a body having an inlet port, an outlet port through a male luer portion of the body, and a fluid path between the inlet port and the at least one outlet ports. A retractable post extends through the fluid path in the male luer sealing a tip of the male luer thereby closing the fluid path when the connector in not activated. There is a seal between the retractable post and the body that forms a fluid volume within a portion of the cavity. The fluid path passes through the fluid volume. When actuated, the retractable post is forced away from the tip of the male luer, thereby opening the fluid path through the medical connector and decreasing the fluid volume.

Abstract: A needleless connector includes a body having a fluid path, a vent path, and a male fitting. The needleless connector also includes a valve disposed within the male fitting. The valve is configured to move between a first configuration, in which the fluid path is blocked, and a second configuration, in which the fluid path is open.
