A safe and reliable medical gas system engineering, in addition to the quality (cleanliness) of medical gases to meet the requirements of the medical pharmacopeia, it is important to ensure the safety and reliability of medical gas system equipment operation.
This article will describe how to ensure the safety and reliability of medical gas system equipment operation.
1.Sufficient pressure and flow
Medical gas manifold (liquid oxygen gas manifold and high-pressure gas cylinder manifold, ensure automatic switching) to provide outlet pressure to maintain constant pressure at the set value, oxygen flow to meet the design requirements of the hospital usage.
Medical compressed air units must have high-performance functions (that is, when the system airflow increases, the air unit can provide sufficient flow at any time to meet the needs of patients and medical equipment) to meet the design requirements of hospital usage, and must have a standby unit.
Medical vacuum suction units must also have high-performance functions (that is, when the system negative pressure flow increases, the negative pressure unit can ensure sufficient pumping flow), to meet the design requirements of hospital pumping capacity, there must have a standby unit.
2.Reliable alarm system
There must be at least two main alarm systems. One for the 24-hour manned area and one for the medical gas maintenance staff and the manager’s studio. The main alarm system monitors the pressure changes of the main road from the station room to the main road between the wards.
An area alarm system must be installed in each individual medical ward area, ICU ward, CCU ward, NICU ward, operating room, etc. to monitor changes in line pressure in these areas.
3.Professional support
The construction plan drawings of the medical gas system must be designed by professional design engineers. The design of various pipe diameters, the location of the alarm installation, and the location of the area valve box installation must be accurately designed and calculated. It must be installed by a professional builder. It is also necessary to carry out the management and maintenance of the medical gas system operation by the hospital’s professionally trained maintenance personnel and to master the requirements for the use of special tools for medical gas equipment.
4.Area valve box reliability
The valve inside the zone valve box should be reliable. An area valve box must be installed in each individual medical ward area, ICU ward, CCU ward, NICU ward, operating room, etc. In particular, the design of the area valve box casing should enable medical personnel to quickly close the medical gas valve in a timely manner in the event of a fire.
5.Medical gas outlet reliability
In order to ensure the safety and reliability of the medical gas outlet, the gas port must be composed of two parts: one is a first-stage gas port valve, and the other is a two-stage airtight self-closing valve so that the gas outlet can be repaired under continuous gas conditions. Ensure that other patients are safe to use when using gas.
