How to plan the medical gas system in the hospital?

Generally speaking, a medical gas system will include 7 parts, medical vacuum pump system, air compressor system, oxygen generator system, medical gas pipeline system, medical gas monitoring system, bedside device and medical gas outlet (terminal). The 7 systems perform their respective duties and work together to achieve the medical gas needs of the hospital.

Planners should design and plan medical gases strictly according to actual needs in the early stage of the project. You can start with the gas outlet components, and then proceed to the design process, gas consumption, switchgear and medical gas pipelines in sequence. Of course, the construction acceptance link is also essential. Specifically:

Point planning

In the planning of the points, the setting requirements of the medical gas outlet components should be considered. According to the different requirements of different departments for medical gases, distinguish and plan in advance the gas outlet components such as oxygen, vacuum, medical air, oxygen mixed gas, nitrous oxide, anesthetic or respiratory waste, carbon dioxide and so on.

Gas consumption calculation and optimization results

Calculate the gas consumption according to the standard, and configure and optimize the gas consumption according to the specific conditions of the hospital. It should be emphasized that a certain margin should be reserved for the gas consumption, because once the occupancy rate increases and the number of beds increases, the hospital can also have room for improvement in gas consumption.

Switchgear and medical gas lines

Switchgear and medical gas lines are selected according to the type of main gas source.

Reasonable planning of the number, location and medical gas alarm points of partition valve boxes

The number and location of zone valve boxes and medical gas alarm points in the hospital are also important. Therefore, the hospital needs to be able to monitor the medical gas. The recommended approach is to install the gas alarm point and the partition valve box at the nurse station, so as to deal with it quickly after the alarm and avoid more problems.

Determine pipe diameter, material

Determine the pipe diameter according to room pipes, corridor pipes and shaft pipes. The pipe material can choose copper pipe and stainless steel pipe, which can be selected according to the situation or according to the needs of the hospital.

Gas outlet

Medical gas outlets (terminals) are used more in central gas supply systems. Its safety and reliability are the key concerns, because once the failure rate is high, it will consume a lot of maintenance resources.

Construction acceptance

Strict on-site management is the guarantee of first-class construction quality. Responsibilities must be clearly defined during the construction and acceptance process, and each link must be strictly supervised to ensure implementation in accordance with early design and reduce errors.
