Diameter Index Safety System
Station Outlets (US) or Terminal Units (ISO, CSA) consist of an outlet port with color-coded faceplate attached to a medical gas supply line, and primary and secondary check valves which open and close automatically upon use and disengagement from the system.CSA Z7396.1-17 - Medical gas pipeline systems - Part 1: Pipelines for medical gases, medical vacuum, medical support gases, and anaesthetic gas scavenging systems In most jurisdictions, Station Outlets are required to be equipped with safety systems that prevent ''cross-connection'' errors, such as connecting a Medical gas supply#Medical air, Medical air Flow measurement, flowmeter to an Medical gas supply#Oxygen, Oxygen port. Hospitals mainly use ''DISS'' connections, though a wide variety of ''Quick connect fitting, quick-connect'' adapters, based on male strikers and female outlet ports, are still in use today. These latter types are easier to connect, but are more prone to leaks and failure. Types Diameter Index Safety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Gas Supply
Medical gas supply systems in hospitals and other healthcare facilities are utilized to supply specialized gases and gas mixtures to various parts of the facility. Products handled by such systems typically include: *Oxygen *Medical air *Nitrous oxide *Nitrogen *Carbon dioxide *Suction (medicine), Medical vacuum *Scavenger system, Waste anaesthetic gas disposal (US) or anaesthetic gas scavenging system (ISO) Source equipment systems are generally required to be monitored by alarm systems at the point of supply for abnormal (high or low) gas pressure in areas such as general ward, operating theatres, intensive care units, recovery rooms, or major treatment rooms. Equipment is connected to the medical gas pipeline system via Station Outlet, station outlets (US) or terminal units (ISO). Medical gas systems are commonly color code, color coded to identify their contents, but as coding systems and requirements (such as those for bottled gas) vary by jurisdiction, the text or labeli ...

Check Valve
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. An important concept in check valves is the cracking pressure which is the minimum differential upstream pressure between inlet and outlet at which the valve will operate ...

Flow Measurement
Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: * Obstruction type (differential pressure or variable area) * Inferential (turbine type) * Electromagnetic * Positive displacement meter, Positive-displacement flowmeters, which accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. * Fluid dynamic (vortex shedding) * Anemometer * Ultrasonic flow meter * Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope. ...

Quick Connect Fitting
For hoses and piping, a quick connect fitting, also called a push fitting or Quick Connect Coupling, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves, quick connect fittings will, upon disconnection, automatically contain any fluid in the line. However, this depends on the type of coupling, such as single shut-off, double shut-off, or straight-through designs, which determine whether fluid retention occurs. Uses There is a large variety of quick connect fittings. They are used underwater, in drilling operations, and in outer space, as well as for pneumatic-power, plumbing, heating, electrical, and fire-suppression applications. Quick connect fittings are intended to be applied more easily than traditional fittings, requiring only that the pipes be pushed together firmly to lock the teeth of ...

Compressed Gas Association
The Compressed Gas Association (CGA) is an American trade association for the industrial and medical gas supply industries. The CGA publishes standards and practices that codify industry practices. In cases where government regulation is inspecific, CGA documents are considered authoritative. CGA falls into a group of trade associations whose publications are relied on by government. These groups include the National Fire Protection Association (NFPA) and ASTM International. For example, the state of Montana, the U.S. Army, and OSHA point to CGA documents for regulatory guidance. Cylinder valve openings The CGA provides detail specifications for the outlet connections of gas containers. They are based on the storage pressure and characteristics of the gas such as flammability, toxicity, state (permanent gas or liquefied) and corrosiveness. These connections are identified by a 3-digit number, such as CGA-555. The range of available connection standards covers the majority of ...

Psig
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suction (medicine)
In medicine, devices are sometimes necessary to create suction. Suction may be used to clear the airway of blood, saliva, vomit, or other secretion Secretion is the movement of material from one point to another, such as a secreted chemical substance from a cell or gland. In contrast, excretion is the removal of certain substances or waste products from a cell or organism. The classical mec ...s so that a patient may breathe. Suctioning can prevent pulmonary aspiration, which can lead to lung infections. In pulmonary hygiene, suction is used to remove fluids from the airways, to facilitate breathing and prevent growth of microorganisms. Small suction-providing devices are often called Aspirator (medical device), aspirators. In surgery suction can be used to remove blood from the area being operated on to allow surgeons to view and work on the area. Suction may also be used to remove blood that has built up within the skull after an intracranial hemorrhage. Suction device ...

Pressure Regulator
A pressure regulator is a valve that controls the pressure of a fluid to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be an integral device with a pressure setting, a restrictor and a sensor all in the one body, or consist of a separate pressure sensor, controller and flow valve. Two types are found: The pressure reduction regulator and the back-pressure regulator. *A pressure reducing regulator is a control valve that reduces the input pressure of a fluid to a desired value at its output. It is a normally-open valve and is installed upstream of pressure sensitive equipment. *A back-pressure regulator, back-pressure valve, pressure sustaining valve or pressure sustaining regulator is a control valve that maintains the set pressure at its inlet side by opening to allow flow when the inlet pressure exceeds the set value. It differs from an over-pressure relief valve in that the over-pressure valve is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Plug
AC power plugs and sockets connect devices to mains electricity to supply them with electrical power. A plug is the connector attached to an electrically operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an Alternating current, AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit. Plugs and wall-mounted sockets for portable appliances became available in the 1880s, to replace connections to light sockets. A proliferation of types were subsequently developed for both convenience and protection from electrical injury. Electrical plugs and sockets differ from one another in voltage and electric current, current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world, and many obsolete socket types are still found in older buildings. Coordi ...
