DEVICE: Flotec (B741MC0)

A length of flexible tube intended to deliver and withstand gases under very high pressure, e.g., greater than 200 bar/3000 pounds per square inch (psi). It may be composed of any of several malleable or semi-rigid materials (e.g., plastic, rubber, or nylon), and braided with cotton wool and/or stainless steel. It is typically used to transport high pressure compressed medical gas to a pressure regulating device. It is available in various lengths, including standard coil lengths. This is a reusable device.

A device intended to regulate the flow of a medical gas [e.g., oxygen (O2), carbon dioxide (CO2), nitrous oxide (N2O), helium/oxygen gas mixture (heliox), medical air] during various procedures (e.g., therapeutic administration, anaesthesia, insufflation during surgery). It has a pre-calibrated adjustable flow selection dial intended to control the gas flow rate; it is not intended to provide flow rate measurements. It will be calibrated to a specific medical gas and have a dedicated flow rate range, therefore some types may be dedicated to a specific patient group (e.g., neonate, infant, adult) or clinical use.

A reduction valve designed to be attached through a gastight connector (e.g., a pin-index or bull-nosed screw thread connection) to the valve stem of a medical gas (e.g., carbon dioxide, oxygen, nitrous oxide, gas mixture) cylinder to reduce high, variable gas pressure to a lower, constant working pressure (excludes procedure-dedicated valves). It can be a single or a dual stage regulator, usually of a piston or diaphragm design. It will have a safety relief valve to avoid excessive pressure due to increased ambient temperatures, and it may have associated devices (e.g., a manometer, flowmeter) to display the available gas reserve of a gas cylinder, the working pressure and/or the flow rate.
