1.The gas outlet should adopt international unit standards; Interface standard should be unified.
Interpretation: medical gas outlet is generally used in the form of plug-in self-sealing joints. It consists of a self-sealing gas socket and a medical gas probe. When in use, insert the hollow gas probe into the gas socket and open the valve inside so that the gas in the pipe can pass through the inner cavity of the socket and the probe. Once the gas probe is pulled out, the flexible element in the seat closes the valve and the gas is prohibited.
The hospital should be the unified configuration of gas outlets, unify the hospital medical gas device standard, which will help repair and reduce routine maintenance costs.
2.The medical gas outlet can choose a set of suspended types and a set of concealed wall-mounted outlets.
Interpretation: Gas outlet device: Medical pendant including anesthesiology pendant, surgical pendant, endoscope pendant, monitor pendant, etc. The use of pendant is different, the installation of gas outlet varieties are also different. For example, anesthesia pendants generally have to be filled with N2O, oxygen, compressed air, vacuum, and anesthesia exhaust emissions gas outlet. Each operating room is equipped with two sets of medical gas outlets: a set of installing on the medical pendant, a set of dark wall-mounted gas outlets, one for normal operation, and one for backup. The medical gas outlets in the room such as the pre-hemp room, awakening room, and ICU Ward are generally installed on the bed head unit.
3.Different types of gas outlet connectors shall not be interchangeable.
The medical gas connector does not allow interchangeability to prevent errors from being plugged into the structure.
Gas source connection error case: A hospital in Beijing, the patient after the inhalation of oxygen, actually inhaled nitrous oxide caused his death; Shanghai, a hospital due to oxygen outlet error, the patient died after inhaling pure nitrogen;
In recent years, 33 ventilator-related deaths in 12 cities in China have caused 8 gas source problems, accounting for 22%.
4.Medical gas probes should use the plug-in self-sealing quick connector.
The probe should be corrosion-resistant, non-toxic, non-flammable, safe and reliable, easy to use, life expectancy should not be less than 20,000 times.
Interpretation: Technical specifications for medical gas pipeline systems require that the life of this probe is 10,000 times and should change the gasket if use more than 1000 times. After replacing the gasket, the service life of the probe should be expanded to no less than 20000 times.
5.The operating room gas outlet should be flush with the wall, the gap seal, the site should be close to the anesthetist working position.
The terminal panel and the wall should be flush with tightness. The distance between the bottom of the outlet and the ground should be 1.0 ~ 1.2m. The gas outlet should be clean and sealed inside.
