摘要:
In one embodiment, a method of filling a container with a liquid drug from a drug reservoir may include: a) connecting a container and a drug reservoir with a cannula such that the drug reservoir and the container fluidically communicate with each other via the cannula, while being hermetically sealed; b) reducing a first volume contained within the container to displace a gaseous medium from the first volume of the container via the cannula into a second volume contained within the drug reservoir; c) increasing the first volume of the container to displace the liquid drug from the second volume of the drug reservoir into the first volume of the container to fill the container; and d) disconnecting the container and the drug reservoir. Before performing action d), action b) and action c) can be successively performed more than once to stepwise increase an amount of liquid drug displaced.

摘要:
A heating coil welding fitting comprising a cylindrical coupling body for welding pipelines made of thermoplastics or other weldable plastics, containing at least two heating wire windings, each with a plurality of turns which are at any desired distance from one another, and contacts for feeding the electric current, wherein the heating wire winding is wavy, preferably sinusoidal, and the coupling can be deformed as a result.
摘要:
A fitting (1) of weldable, thermoplastic material of a modular structure, comprising a number of elements (2, 3, 9, 10, 11, 12), at least one main element (2, 9) and at least one connecting element (3, 10, 11, 12), characterized in that the elements (2, 3, 9, 10, 11, 12) have end faces (4, 5) at right angles to the center axis (8), and the elements (2, 3, 9, 10, 11, 12) are welded to one another exclusively at the end faces (4, 5).
摘要:
A method and a device for welding plastic pipes (1) made of thermoplastic material by a butt-welding method, wherein the pipes (1) are held in a coaxial position in relation to one another by clamping points (2), are trimmed by a trimmer (3), which can be brought between the clamping points (2), and are heated up by heated tools (6), which can be fitted in place of the trimmer (3), wherein the heating of the free pipe ends (8) to be welded has the effect of forming a melting region which forms a bead when pressing occurs, the pipe projection (5) of the pipes (1) being trimmed to a defined size.
