Abstract:
An electroactive material (e.g., a doped electroactive polymer, or an intercalcated carbon/graphite fiber) responsive to the concentration of a chemical component is used to sense the concentration of the chemical component inside a chamber. The conductivity, or other electrical property of the electroactive material, varies in response to the exposure to the chemical component.
Abstract:
A system capable of cleaning and disinfecting a filter. A filter element is flushed with a disinfectant solution in a direction opposite to fluid filtration. A filter integrity test checks the integrity of the filter by pressurizing the filter.
Abstract:
When microbial contamination is introduced into a room (20*) of an enclosure, such as a building, an HVAC system including supply ductwork (16) and a return ductwork (34) is decontaminated with hydrogen peroxide vapor. A decontamination controller (46) operates controllable baffles (22) at outlet registers (20), temporary controllable baffles (44) at inlet registers (30), and a blower system (10) to circulate hydrogen peroxide vapor from hydrogen peroxide vapor generators (42) through the ductwork in both forward and reverse directions. Further, at least portions of the baffles are closed to create dwell times in which the hydrogen peroxide vapor resides in the ductwork with minimal or turbulent flow.
Abstract:
A treatment system for treating objects (e.g., medical instruments) with ozone gas. The ozone treatment system includes a treatment tank wherein the objects are exposed to ozone. In a preferred embodiment, the ozone is generated within the treatment tank by exposing an oxygen-containing gas to ultraviolet radiation produced by a laser.
Abstract:
A method of irradiating a fibrous organic material comprising the steps of: conveying an organic material formed into a cord-like configuration between two spaced-apart support members; and supplying a charged particle beam to the organic material at a location between the support members.
Abstract:
A system for irradiating mail, comprising a device for conveying mail along a predetermined path and a device for irradiating the mail moving along the path with a beam of electrons. An apparatus for chilling the mail is provided along the path. The apparatus exposes the mail to a low-temperature, gaseous fluid created using a cryogenic fluid.
Abstract:
A suspension system is disclosed for suspending lightheads, monitors, cameras, or other medical apparatus from an overhead structure at a selectable height. A drop tube has a selected portion thereof surroundingly encompassed by a receiving element that has a variable inside diameter substantially conforming to a frustum of a cone. A mounting plate rigidly connects with the overhead structure and with the receiving element. The mounting plate has an opening through which an end of the drop tube passes. A wedge-shaped element has a variable outer diameter substantially conforming to a frustum of a cone. The wedge-shaped element compressively inserts into the receiving element and surroundingly encompasses the selected portion of the drop tube to effectuate a compressive clamping of the selected portion of the drop tube inside the receiving element.
Abstract:
An enclosure assembly (10, 10, 10) includes a framework (12) formed from structural members and a flexible transparent enclosure (14) which provides an enclosed space for isolation and or treatment of patients, equipment, and the like. A treatment material, such as hydrogen peroxide or other gaseous or vapor sterilant, may be fed to the enclosure to microbially decontaminate or otherwise treat the equipment. The enclosure is quickly assembled and disassembled after use, making it suitable for treatment of large pieces of equipment which are not readily moved or which are too large to be accommodated conventional sterilization equipment.
Abstract:
A video/data/power quick connect system is provided for use with medical appliance suspension arms. A universal cable bundle (40) extends along a monitor suspension arm (12). A first hub harness (50) adapts the cable bundle (40) for connection to a first associated source (68) of video/data/power signals. A first monitor harness (60) connects a lower end of the cable bundle (40) for connection to a first associated monitor device (34). A second hub harness (50null) and second monitor harness (60null) are provided for adapting the cable bundle (40) for connection to a second source (68) of associated video/data/power signals and a second associated monitor device (34null), respectively.
Abstract:
An optical coupler includes essentially tubular second connecting piece (40). Second fiber end (14) inserts completely through second connecting piece (40) and is held rigidly such second fiber end (14) is set back from second connecting piece end (78) by a preselected distance. First essentially tubular connecting piece (16) is divided axially into first portion (30) into which first fiber end (12) is inserted and held rigidly, and second portion (32) into which second connecting piece (40) is detachably attached. First and second portions (30, 32) are arranged such that first fiber end (12) is coaxial with and in close proximity to second fiber end (14). Preferably, attachment of second and first connecting pieces (40, 16) includes an axially symmetric groove (46) on an outer surface of second connecting piece (40), and an axially symmetric protrusion (24) on an inner surface of second portion (32) which essentially mates with axially symmetric groove (40).
