Filter assemblies are described. In particular, a filter securement assembly for receiving and retaining a filter media in an exhaust hood includes a main panel defining a first end and an opposed second end, a first retainment surface adjacent the first end of the main panel, a first retainment lip adjacent the first retainment surface, a second retainment surface adjacent the second end of the main panel and a second retainment lip adjacent the second retainment surface.

A method for the dry filtration of a gas flow carrying foreign objects, a filter device for cleaning off waste gas resulting from additive manufacturing technologies, comprises feeding a raw gas flow containing foreign objects into a raw gas space of a filter unit having at least one filter surface separating a raw gas side from a clean gas side; feeding oxidant to a reaction region located on the raw gas side of the filter surface downstream of the filter surface; such that foreign objects contained in material cleaned off from the filter surface and/or in the raw gas flow react with the oxidant in the reaction region to form oxide-containing foreign objects.

In a method of treating a gas stream (32) containing combustible and/or reactive particles (34) at least a part of the particles (34) contained in the gas stream (32) is separated from the gas stream (32) by means of a separation device (36). The particles (34) separated from the gas stream (32) by means of the separation device (36) are supplied to a collecting vessel (40). The supply of particles (34) to the collecting vessel (40) is interrupted. A flame retardant material (57) is supplied to the collecting vessel (40) so as to form a cover layer of flame retardant material (57) on the particles (34) contained in the collecting vessel (40).

An automated dose-response record system including a module for housing waste-heat producing electronic and electromechanical medical equipment including at least one physiologic monitor, and including a system to measure, temporally correlate and record dose and response events.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

An anesthetic equipment storage and waste air management module configured to housing electronic and electromechanical surgical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration. The module can include a housing having a lower section and a tower-like upper section, wherein the lower section is configured to house unrelated waste heat-producing electronic and electromechanical surgical equipment. The module can also include a cowling that substantially confines waste heat generated by the unrelated waste heat-producing electronic and electromechanical surgical equipment, and can include a system for measuring and recording the administration of the one or more IV medications and fluids.

A passivation device for passivating filter residues of a filter device arranged in a process gas circuit of an additive manufacturing apparatus includes a reaction unit having an inlet suitable for supplying an oxidant, a coupling unit adapted to be coupled to the filter device for introducing filter residues into the reaction unit, a discharge unit suitable for discharging passivated filter residues from the reaction unit, and an energy supply unit suitable for effecting a reaction between the filter residues and the oxidant in the reaction unit.

Examples of a module for housing unrelated electronic and electromechanical equipment for use during surgery. The module can include a lower section and a tower-like upper section. The lower section can house unrelated electronic and electromechanical equipment. The tower-like upper section can be located on top of the lower section. A water-resistant cowling can enclose at least a portion of the lower section and the tower-like upper section. A cartridge containing one or more ultraviolet-C producing lights can be protectively housed within the tower-like upper section. The cartridge containing one or more ultraviolet-C producing lights can be configured to emerge upward from a top of the tower-like upper section to substantially seat itself on the top of the tower-like upper section when activated allowing the ultraviolet-C light to disinfect the patient and staff-contacting upper surfaces of the equipment in the operating room.

Module for housing electronic and electromechanical medical equipment including a portable digital camera and processing circuitry with machine vision and machine learning software for automatically documenting healthcare events and healthcare equipment operations in the electronic health record.
