Medical Gas Pipeline System

Medical Gas Pipelines 

 Medical Gas Pipelines are used to supply nonflammable gases |( oxygen, nitrous oxide, medical air, etc.) from a central manifold to color-coded pipeline distribution network, which gets terminated in non-interchangeable sockets ( diss) non interchangeable threads or non-changeable quick couplers present in the wall outlets , ceiling pendants, bed head panels etc. 

medical gas pipelines 

The material used to make these pipelines is copper. outer diameter of vaccum pipeline is 15mm and outer diameter of other gases pipeline is 12mm .

ideally, appropriate markings of pipes should be done ( at least 20 feet and once in every room .)and flow of gas should be displayed .

GENERAL RULE OF KEEPING AWAY PIPELINE from  : 

1. MECHANICAL DAMAGE 
2. CHEMICAL DAMAGE 
3. EXCESSIVE HEAT 
4. ELECTRICAL SPARKS 

There are 3 component in medical gas pipeline . 

1. SOURCES 
2. DISTRIBUTION SYSTEM 
3. OUTLETS 

 SOURCES:

Oxygen is supplied from oxygen cylinder manifold or VIE . and color coding of oxygen pipeline is white .. 

Medical air is supplied from cylinder manifold or compressor. and color coding of medical air pipeline is black .  

Nitrous oxide is supplied from nitrous oxide cylinder manifold and colour coding of nitrous oxide pipeline is french  blue .

 DISTRIBUTION SYSTEM :  

There are generally 3 classes of pipeline 

Medical Gas Pipeline System 

1. Main pipeline 
2. Risers 
3. Branch lines (lateral)

1. The main pipeline. 

They connect two sources to risers or Branch lines or both. 

2. Risers. 

They are vertical pipes which connect main line with Branch lines. 

3. Branch lines. Also known as literal lines. 

They are the little pipes that Supply medical gas to a roof or group of rooms on same level of the facility. 

In distribution system, there are various devices that ensure the proper functioning of the distribution system. 

Distribution system. Consists of a shutoff valve  

shutoff valve   are very important in distribution system as it allows us to isolate a particular distribution system in any event, like maintenance repair or testing Etc. There are two types of shut-off walls. First manual. Second service valve. 

Manual. Shutoff valve  are installed in a visible and easily accessible place. So that in  case of an emergency  Any person can  easily close it  

Service walls are used by, only authorized personnel. 

Classification of shut-off valves. 

A. Service shutoff valves:

1. Main service shutoff valve 

2. Riser service shutoff valve

3. Lateral service shutoff valve

4. Equipment service shutoff valve.

B. Manual/Zone shutoff valves  in boxes with fixed covers or doors.

Pressure relief valve. Pressure relief valve. 

Pressure relief valves are installed in pipelines so that if the pressure of the Central Medical gas pipelines is above  or below of 33 % of ideal. Pressure. Then these walls open and try to maintain the pressure. 

As soon as. Pressure is balance. These walls should be closed. 

They are they play a very important role in preventing the pressure buildup. In pipeline. Alarms. 

Master alarm system is used to monitor. 

The central gas supply of all Central Medical gas supply of all the gases at one place. It is the central part central control room from where monitoring. Is done and is responsible for the smooth and continuous supply of medical gas. 

Area alarm system. 

As. Operation theater icu  like departments. Require continuous medical gas supply. 

They have their own area alarm system, which indicates the pressure. 

And gives a warning if Central pressure increases or decreases. 

Area alarm systems  are always placed Downstream. 

Local alarm.

 Installed in control panel or in the monitoring devices. 

Then there comes the terminal unit. 

Terminal units 

are placed according to the need, They can be attached on wall.. Outlets are color coded. 

For identification. 

They are equipped with non interchangeable. Safety keyed, plug connectors. 

Now, I'm going to tell you about components of risk of termination. Units. 

Base block. 

Base block is attached to the terminal part of distribution system. 

Primary valve 

 is automatic shut-off wall, which is also called as self sealing wall. 

Secondary valve. 

The secondary valve (secondary shutoff valve, secondary check

valve) is designed to shutoff whenever primary valve is removed .

Gas-specific Connection Point

(Socket Assembly)

it is attached to base block  ( DISS )

OUTLETS 

Types of terminal units,

1.  Fall Outlets
2. . Ceiling-mounted horses. 
3. Ceiling pendants. 
4. Ceiling columns. 
5. Horizontal Bed. Head panels. 
6. Flexible horses flexible Pipelines.
7.  Oxygen flow meter with humidifier.
