Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.

The present disclosure provides an apparatus for disinfecting and cleaning an item intended to be worn multiple times, the apparatus comprising a chamber having an inner volume sufficient to accommodate the item intended to be worn multiple times and an ultraviolet (UV) light source disposed to shine UV light onto a surface of the item configured for placement against skin of a user.

A defouling device for mechanically disrupting fouling material for removal from a pipe or other a tubular member. The defouling device has inflatable portions capable of expanding to mechanically disrupt fouling material within a pipe. The defouling device may be attached to an inner luminal surface of the pipe or formed with the pipe. The defouling device expands circumferentially and radially to mechanically disrupt fouling material. The defouling device may also controllably expand longitudinally to mechanically disrupt fouling material and peristaltically pump fouling material through and out of the pipe.

An anti-fingerprint terminal housing includes a housing substrate, where the housing substrate includes a first surface and a second surface that are oppositely disposed, the first surface faces the exterior of the terminal housing, and the second surface faces the interior of the terminal housing, the first surface is provided with a plurality of spaced convexes or concaves formed by the housing substrate, a distance between boundaries of any two adjacent convexes or concaves on a same side is in a range of 1-900 nanometers (nm), and the height of the convex or the depth of the concave is in a range of 1-400 nm.

A condensation management apparatus comprises a microstructured film arranged to condense water vapor on an underside of a substantially horizontal surface. The film comprises channels disposed at least on a first major surface and configured to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the film. A capillary siphon structure of the film comprises a fold in the film, a condensate collection region proximate the fold, and a siphon region between the fold and a condensate release location of the film. At least a portion of a second major surface is attached to the underside of the substantially horizontal surface such that longitudinal openings of the channels of the condensate collection region are oriented towards a direction of gravity and the condensate release location is positioned lower along the direction of gravity than the condensate collection region.

The present invention is concerned with a superhydrophobic surface arrangement, an article having the same and a method of making same. The arrangement is configured for generating, upon contact by water droplets, pancaking bouncing and reducing liquid contact time. The arrangement has an array of posts residing on a surface and extending from the surface, said posts having an elongate configuration with a base portion at one end and an upper portion at an opposite end. By way of the configuration of the posts and the Weber number the surface arrangement in use pancake bouncing of liquid droplets and reduction of contact time of the liquid droplets are effected.

Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

The present invention relates to structured, gas-holding surfaces for improving the friction-reducing properties of gas layers held under a liquid and for the simultaneous suppression of turbulence. The present invention furthermore relates to a device comprising this structured, gas-holding surface and to the use of this structured, gas-holding surface.

A synthetic polymer film (34A), (34B) having a surface which has a plurality of raised portions (34Ap), (34Bp), wherein a two-dimensional size of the plurality of raised portions (34Ap), (34Bp) is in a range of more than 20 nm and less than 500 nm when viewed in a normal direction of the synthetic polymer film (34A), (34B), the surface having a microbicidal effect, and a concentration of a total of a nitrogen element which is a constituent of a primary amine and a nitrogen element which is a constituent of a secondary amine is not less than 0.29 at %, and a number of moles of an ethylene oxide unit included in one gram is more than 0.0020 and not more than 0.0080.
