The present disclosure relates to an electrical connector for providing signal isolation between various components of a physiological monitoring system. In an embodiment, the electrical connector is placed between a sensor and associated monitoring system and includes a physical barrier and inductive components.

The present application provides a device and methods of making and using these devices. The devices comprise porous caps and porous vents made from sintered porous polymeric media comprising plastic particles, elastomeric particles or a combination thereof. These devices are used with medical devices or components thereof to provide ease of use, resistance to infection, sterilization and venting.

The invention provides a packaging for a medical article e.g. for a urinary catheter. The medical article is stored in a compartment and can be accessed by detaching a first element from a second element thereby forming an opening into the compartment. The first element comprises a suction cup or another fastening element by which the packaging is attachable to a surface. Due to the structure of the packaging, it can be supported in an orientation in which the opening is remote from the surface, and risk of contamination of the medical article can therefore be reduced during removal of the article from the packaging.

A reactor for plating a metal onto a surface of a workpiece is set forth. The reactor comprises a reactor bowl including an electroplating solution disposed therein and an anode disposed in the reactor bowl in contact with the electroplating solution. A contact assembly is spaced from the anode within the reactor bowl. The contact assembly includes a plurality of contacts disposed to contact a peripheral edge of the surface of the workpiece to provide electroplating power to the surface of the workpiece. The contacts execute a wiping action against the surface of the workpiece as the workpiece is brought into engagement therewith The contact assembly also including a barrier disposed interior of the plurality of contacts. The barrier includes a member disposed to engage the surface of the workpiece to assist in isolating the plurality of contacts from the electroplating solution. In one embodiment, the plurality of contacts are in the form of discrete flexures while in another embodiment the plurality of contacts are in the form of a Belleville ring contact. A flow path may be provided in the contact assembly for providing a purging gas to the plurality of contacts and the peripheral edge of the workpiece. The purging gas may be used to assist in the formation of the barrier of the contact assembly. A combined electroplating / electroless plating tool and method are also set forth.

A collecting bag is provided with a vent aperture to allow for escape of gases which may accumulate in the bag during use. The vent aperture is formed in an extension member that is connected with the bag member. In order to bring the vent aperture from a fully open condition to a fully closed condition, the extension member is folded at least once along a folding line, thereby bringing a first engagement surface into engagement with a second engagement surface. A net element may be positioned between the inlet opening of the bag member and the extension member and a filter device may be positioned within the extension member.

A process for cultivating photosynthetic microbes comprising Closed Systems for continuous cultivation and Open Systems for batch cultivation, in which (a) the Closed System Area occupies no more than 20% of the Total Land Area of the cultivation facility; (b) batch cultures in the Open Systems are initiated with an inoculum from the Closed Systems containing a cell biomass of no less than 5% of the carrying capacity of said Open System; (c) the doubling rate of said photosynthetic microbe is no less than once every 16 hours; and (d) the residence time of the batch culture in said Open System is no more than a period of 5 days.
