摘要:
A fluid management apparatus includes a substrate having a first surface and a second surface opposite to the first surface. A plurality of fluid inlets, which are preferably media reservoirs, are formed in a first pattern in the first surface of the substrate. A plurality of fluid outlets, which are preferably nozzles, are arranged in a second pattern, which is different from the first pattern, in the second surface of the substrate. A plurality of fluid ducts formed in the substrate for connecting respective fluid inlets with respective fluid outlets are provided so that a format conversation from the fluid inlets to the fluid outlets is effected. The fluid outlets have opening cross-sections smaller than that of the fluid inlets. Furthermore, the fluid inlets may be arranged in the raster scheme of microtiter plates.

A method that relates to the fields of polymer chemistry, pharmacy and medicine and releases drugs as a component of implants into the environment of the implant. A method that, in a simple and easily reproducible manner, generates a drug delivery system, which releases drugs in a locally targeted and controllably delayed manner. Polyanions and polycations are mixed in a liquid in a non-stoichiometric ratio, relative to the charged monomer units, wherein drugs are added to the polyelectrolytes either before, during or after the mixing, or charge-carrying drugs and an oppositely charged polyelectrolyte are mixed, and after the mixing the polyelectrolyte complex produced is applied to the surface of a medical structure or material or is positioned on the surface directly at the location where the drug is to be released.

The subject matter disclosed herein provides, methods and apparatus, including computer program products for the management of a view of a data structure. In one aspect, there is provided a method that may include generating a view of a data structure. The data structure and the view may include a plurality of nodes and at least one association. This method may further include determining, at run time, whether the generated view is invalid based on an indicator. The indicator may represent whether a change has occurred to a system including the view. This method may further include deleting, at run time, the view based on the results of the determining. Related apparatus, systems, techniques and articles are also described.

A device for injecting fuel includes an outwardly opening valve needle, a piezo actuator connected to the valve needle, a valve body having a first through-opening, and a holding body connected to the valve body and having a second through-opening. The valve body has a valve seat and a first guide region for guiding the valve needle, the valve needle being disposed in the valve body and in the holding body, and the first through-opening is formed in the valve body without undercutting.
摘要:
The invention relates to the fields of polymer chemistry, pharmacy and medicine and relates to a method, which for example releases drugs as a component of implants into the environment of the implant. The object of the present invention is to disclose a method which in a simple and easily reproducible manner generates a drug delivery system, which releases drugs in a locally targeted and controllably delayed manner. The object is attained by a method in which polyanions and polycations are mixed in a liquid in a non-stoichiometric ratio, relative to the charged monomer units, wherein drugs are added to the polyelectrolytes either before, during or after the mixing, or charge-carrying drugs and an oppositely charged polyelectrolyte are mixed, and after the mixing the polyelectrolyte complex produced is applied to the surface of a medical means or is positioned on the surface directly at the location where the drug is to be released.
