Abstract: There is provided a mobile self-powered medical services trolley for use in a surgical operating theatre. The trolley includes a portable power supply in the form of battery system that powers the trolley without the need for an external power source (such as mains power) to be wired to the trolley. The trolley includes a plurality of electrically powered medical instruments and other electrically powered devices integrated onto the trolley and powered by the battery system for use in medical procedures carried out in the theatre. The plurality of medical instruments includes: a suction instrument; a gas supply apparatus; and wireless data communication unit in communication with a central computer network, for both sending and receiving data. The trolley further includes a multimedia input in the form of a connector port which is configured to connect to a video capture device.

Abstract: A fluid delivery system for a dental cleaning appliance includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a fluid conduit for conveying working fluid to the nozzle. A body of the nozzle defines a fluid chamber and a channel for conveying working fluid from the fluid chamber to a fluid outlet from the nozzle. The fluid chamber has a tangential inlet for receiving working fluid from the fluid conduit.

Abstract: A dental cleaning appliance includes a nozzle having a fluid chamber, a fluid outlet and a channel extending between the fluid chamber and the fluid outlet. A water reservoir provides water to a pump for generating a burst of pressurized water, which is supplied to the nozzle by a fluid conduit. Following the delivery of the burst of water to the teeth of the user, a valve draws water back into the fluid chamber from the channel to prevent that water from dripping from the fluid outlet before the next water burst is generated by the pump. Simultaneously, air may be drawn into the fluid chamber, for example, through the fluid outlet, for mixing with the next water burst to generate a fluid burst for delivery to the user's teeth.

Abstract: A tool employable to install a garbage disposal supported in an elevated position by a mounting ring rotationally engaged to a sink flange extending from a drain. The device provides one or a plurality of handles extending from a supporting member adapted to cradle or engage with projections extending from the mounting ring. With the supporting member engaged to the mounting ring the user may employ two hands to lift the mounting ring and disposal and concurrently twist the mounting ring onto the sink flange.
