摘要:
A device for administering injections includes a housing having an upper end, a lower end including a bottom surface with an injection needle opening, and an axis extending between the upper and lower ends. The device includes an injection needle disposed within the housing for moving between a retracted position and an extended position.
摘要:
A process for making a framed electrode by injection molding. The process comprises placing a flat piece of electrode material on a shrinkage-free under mold frame and attaching it thereto in a manner which substantially prevents the piece and the frame from moving relative to each other, over molding the resultant assembly by injecting a molten resin into an over molding cavity which contains the assembly, and allowing the resin to solidify. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
摘要:
The invention relates to an applicator tip for spraying and/or mixing at least two fluids that react together, the tip comprising: at least two fluid conduits for carrying the at least two fluids, each conduit having at least one outlet opening, the openings are positioned substantially on a same plane; at least two gas conduits for carrying a gas volume, each gas conduit comprises a proximal gas tube and a distal gas tube, each distal gas tube is bent as compared to the position of the proximal gas tube, and each distal gas tube has one gas opening positioned distal from the plane of the outlet openings; and a housing for accommodating the at least two fluid conduits and the at least two gas conduits. The device allows efficient spraying in close proximity to a surface.
摘要:
Provided are methods and devices for dissolving solid protein compositions, such as solid compositions comprising fibrinogen, in an aqueous solvent. The methods comprise use of a closed container containing a volume of solid fibrinogen composition and a head space wherein the pressure within the headspace is sub-atmospheric. Aqueous solvent is introduced into the container while maintain the sub-atmospheric pressure, and subsequent to addition of the solvent, the size of the headspace is decreased to bring the pressure to atmospheric pressure. The devices are suitable for use in the disclosed method.
摘要:
The device for administering an at least two-component substance comprises a concentric lumen arrangement including (i) an inner cannula having a lumen with an inlet opening at a first end and a tip with an outlet opening at a second end opposite its first end, and (ii) an outer sheath having opposite first and second ends facing the respective first and second ends of the inner cannula, and surrounding the inner cannula along an axial length between the first and second ends of the inner cannula, wherein the outer sheath at its second end is sealingly and fixedly connected to the inner cannula and defining an outer lumen around the inner cannula, and wherein the inner cannula is provided with at least one opening for providing fluid communication between the outer lumen around the inner cannula and the lumen of the inner cannula.
