A nasal/oral cannula for collecting a flow of exhaled gases and its method of manufacture are disclosed. The cannula comprises an elongated tubular body having a first and a second end portion, a surface and an internal volume; a wall internally disposed within said tubular body, said wall defining a first subvolume of said internal volume in the lengthwise direction of the tubular body; and an inlet through said surface, for introducing exhaled gases into said first subvolume. The first end portion defines an exit port for exhaled gases from said subvolume, and said wall is arranged directly adjacent to said inlet.

An object of the present invention is to provide, in the manufacture of a membrane-catalyst assembly including a polymer electrolyte membrane and a catalyst layer bonded to the polymer electrolyte membrane, a method that achieves both the relaxation of thermocompression bonding conditions and the improvement of adhesion between the catalyst layer and the electrolyte membrane with high productivity. A main object of the present invention is to provide a method of manufacturing a membrane-catalyst assembly including an electrolyte membrane and a catalyst layer bonded to the electrolyte membrane, the method including a liquid application step of applying a liquid to a surface of the catalyst layer before bonding, and a thermocompression bonding step of bonding, to the electrolyte membrane, the catalyst layer to which the liquid is applied by thermocompression bonding.

A laminate including a base member, and a hydrogel layer whose forming material is a hydrogel, the hydrogel layer being provided on a surface of the base member. An adhesive region and a non-adhesive region are formed at an interface between the base member and the hydrogel layer, the adhesive region being a region where the base member and the hydrogel layer adhere to each other, the non-adhesive region being a region where the base member and the hydrogel layer do not adhere to each other.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

The invention relates to a process for bonding a silicone or silicone based material to a polyurethane and use of the bonded silicone-polyurethane in the manufacture of biomaterials, devices, articles or implants, in particular long term implantable medical devices in the fields of cardiology, orthopedics, plastic surgery and gastroenterology. The process involves the steps of (a) flame treating a surface of the silicone or silicone based material and (b) bonding the polyurethane to the flame treated surface of the silicone or silicone based material.

Methods for joining surface features to wind turbine rotor blades are provided. A method includes providing the surface feature after forming of the rotor blade. The surface feature includes a thermoplastic resin. The formed rotor blade includes a plurality of blade components joined together to form an exterior surface defining a pressure side, a suction side, a leading edge, and a trailing edge each extending between a tip and a root. The formed rotor blade further includes a thermoplastic resin. The method further includes positioning the surface feature adjacent the exterior surface, and welding the thermoplastic resin of the surface feature and the thermoplastic resin of the formed rotor blade together.

The present disclosure provides methods of improving adhesion of a non-di-(2-ethylhexyl)phthalate (DEHP) plasticized polyvinyl chloride (PVC) to an acrylic-based polymer or an ABS-based polymer. Such methods may comprise blending the acrylic-based polymer or ABS-based polymer with an impact modifier so that a rubber content in the acrylic-based polymer or ABS-based polymer is greater than 12% (w/w). Also provided are components of a device (e.g., a medical device) made by the disclosed methods.

A method of manufacturing a microfluidic device comprises molding a substrate using a master die having at least one outer stepped formation; and forming at least one microstructured formation having an outer rim, the depth of the outer rim being shallower than that of the microstructured formation.

A microfluidic device includes a first substrate made of a first polymer material and a second substrate made of a second polymer material, the first and second substrates having respective bonding surfaces, at least one of the bonding surfaces having channel formations so that, when the bonding surfaces are bonded by surface deformation to one another, the bonded first and second substrates and the channel formations form at least part of a microfluidic channel network comprising a plurality of microfluidic channels, wherein one or more indicator pits, separate to the channel formations defining the microfluidic channel network, are formed in at least one of the bonding surfaces, so that surface deformation caused by the bonding process causes a change of configuration of the one or more indicator pits.

Rotor blades and methods for joining blade components of rotor blades are provided. A method includes positioning an insert between and in contact with a first blade component and a second blade component. At least one of the first blade component or the second blade component includes a thermoplastic resin. The insert includes a thermoplastic resin and an energy absorptive pigment.
