Protective vacuum shield

Protective vacuum shield for personal service providers

A system includes a housing assembly having a top, side, middle, and bottom portions, a pair of hollow, tubular, elongated members having a top and a bottom end, the top portion of the housing assembly attached to the bottom end of the elongated members, the top end of the one or more elongated members having a brackets configured and arranged to mount to an overhead surface area, one or more ambient lighting assemblies attached to side portions and top portion of the housing assembly to provide general lighting, each ambient lighting assembly including an ambient housing and fluorescent bulbs, a horizontal tracking rail suspended attached to a bottom portion of the housing assembly, the tracking rail extending along a portion of the housing assembly, a carriage mechanism slidably engaging the tracking rail, and an intra-oral light assembly connected to the carriage mechanism.

Track lighting system

A unit includes a rail system having a trolley and first and second hook rails that are configured to mate with corresponding portions of a mounting board secured to a ceiling, a length between the first and second hook rails approximately equal to a width of the mounting board to insure a snug fit, an arm system configured to link to the rail system and having an upper tube section, a middle tube section and a lower tube section, an end of the upper tube section including slip ring wire connections to enable the upper tube section to rotate within the rail system, and an illumination unit configured to link to the lower tube section and having an end of the lower tube section including slip ring wire connections to enable the illumination unit to rotate with respect to the lower tube section.

Fast track dental operative unit

The present invention is a nitrous oxide safety system or method that provides a safety control valve actuated by low-vacuum fluids to control the release of nitrous oxide therethrough. The nitrous oxide safety system may include a low-vacuum fluid, a nitrous oxide fluid, a scavenging mask assembly, and a safety control valve. The low-vacuum fluid is generated by a vacuum source operating to achieve a predetermined parameter and the nitrous oxide fluid is provided by a nitrous oxide source. The scavenging mask assembly is fluidly connected with the nitrous oxide source and the vacuum source. The safety control valve is fluidly connected to the fluid connection between the nitrous oxide source and the vacuum source. The safety control valve is configured to be actuated when the low-vacuum fluid is input to the valve to release a flow of the nitrous oxide fluid through the safety control valve.

Nitrous oxide safety system

A system and method for administering nitrous oxide to a patient has a fluid control system that allows a user to monitor and control the supply of gases to a patient. A shutoff valve allows a user to selectively activate the fluid control system. Oxygen flow is adjusted by a flow controlling valve. A differential pressure regulator allows flow of nitrous oxide in response to sufficient oxygen flow. Flow of the nitrous oxide is further controlled by a ratio controlling valve. A display shows the flow of the gases through the fluid control system. A flush valve allows a user to flush the output with oxygen. A flow indicator light may be included. An optional output selector allows the user to direct the flow to one of various output ports. An optional safety scavenge valve prevents operation of the fluid control system when there is insufficient scavenge vacuum pressure.

Nitrous oxide anesthetic administration system

A pendant mounted track lighting system includes an electronic display for use in an operatory environment. In particular, the invention is directed towards a pendant mounted track lighting system that incorporates and integrates intraoral illumination for illuminating a patient's mouth area, general room or ambient lighting in the operatory environment for patients and practitioners, directional task lighting for work surface areas, and electronic display for patient stimulation. The track lighting system includes a housing assembly attached to one or more elongated members for attachment within the operatory environment, one or more ambient lighting assemblies, an intraoral light assembly having a carriage mechanism, an electronic display, and one or more directional task lighting assemblies in a single track lighting system.

The present invention is a method and system for administering nitrous oxide. The system includes a fluid control system for controlling the flow of nitrous oxide and oxygen to the patient. A nitrous oxide and oxygen supply, vacuum source, a breather bag, and a nasal delivery interface system are fluidly connected to the fluid control system and a patient. The fluid control system also includes a safety scavenge system including a mass airflow sensor, master controller, nitrous oxide valve, and alarm. The mass airflow sensor reads the scavenging vacuum pressure which it communicates to the master controller. Depending upon the scavenging vacuum pressure, the master controller can activate an alarm or shut off the flow of nitrous oxide. In operation, the present invention provides a system for administering anesthesia/analgesia gas which prevents excessively high volumes of exhaled nitrous oxide in the operatory environment through monitoring of the scavenge vacuum pressure.

A method of imparting soil resistance to a substrate comprising applying to the substrate a composition comprising a) a polyfluoro organic compound having at least one urethane or urea, b) 1,3-propanediol, and c) a surfactant, the soil resist composition having freeze thaw stability.

Soil resist method

A soil resist composition comprises a) a polyfluoro organic compound having at least one urethane or urea, b) 1,3-propanediol, and c) a surfactant, the soil resist composition having freeze thaw stability.

Propanediol soil resist compositions

A composition comprising a mixture of at least one soil resist agent and at least one additive which is maleic anhydride, and a method of providing soil resistance to fibrous substrates are disclosed.

Soil resist additive

A method for recovering a solvent from its mixture containing oligomers extracted from grafted polyolefins is disclosed. The method includes distilling the solvent from the mixture in the presence of a naphthalene compound. The method of the invention significantly increases the solvent recovering yield without causing the vessel fouling.
