医用氧气的浓度区别与法规标准
医用氧气的浓度区别与法规标准Company number：【0089WT-8898YT-W8CCB-BUUT-202108】医疗用氧的浓度区别与法规标准医疗氧气是医院疾病预防与治疗必不可少的组成部分，也是医院用气量最大的医用气体，是生命支持系统的重要构成。
因氧气对人体的重要作用，尤其是在医疗急救上的应用，医疗氧气的供气方式与氧源方式逐步演变与发展。
供气方式由起初的分散性供氧到如今的集中性供氧，医院供氧系统氧源方式也从单一的瓶装氧到如今的液氧、分子筛制氧三足鼎立，医院中心供氧整体朝着安全、自主、现代化不断更迭，泰瑞医疗等一批先进的氧业单位技术也在不断革新。
人体与临床氧浓度需求氧是人体生理代谢的基本元素，构成人类形状的细胞和生命现象的中轴存在——大脑﹑心脏﹑肺以及维持它们的血液，离开氧气都无法继续活动。
而且氧气含量的高低对人体的影响是非常直接、明显的。
现今空气中的氧气含量在21%左右，当氧气含量过低时，人体会出现缺氧状态，严重缺氧时会危及生命；而当氧气含量过高时，也会对人体产生一定的损害，如果人呼吸的是纯氧，会引起“氧中毒”现象。
所以从人体生理角度考虑，并不需要吸入高浓度氧气，一般吸入的是稀释后的氧气。
据泰瑞医疗了解，临床上对使用医疗氧气有着不同的需求，根据临床用氧的特点，可分为普通病床用氧、高压氧舱用氧、麻醉机呼吸机以及ICU病房用氧。
普通病床用氧一般是在常压状态下吸氧，多采用鼻塞给氧，有严重呼吸功障碍患者则采用面罩给氧、鼻导管给氧。
主要用于疾病的治疗与预防，普通病人吸氧量为min，氧气浓度一般控制在24%-35%。
高压氧舱是在加压状态下吸氧，以介质来说医用有两种:（1）氧气加压舱:用高浓度氧，稳压后病人直接呼吸舱内的氧，氧浓度一般是在80%以上。
（2）空气舱:用空气加压，稳压后根据病情，病人通过、氧帐，直至吸氧，氧浓度需控制在25%以下。
高压氧舱氧源的选择在临床上没有明确限定，主要是要求瞬时用氧量大，氧气压力高。

The negative pressure source system is attracting center to attract vacuum pump station, the vacuum pump suction to suction system to reach the required value of negative pressure pipe, suction generated in the terminal at the operation room, resuscitation room, therapeutic room and each ward, to provide medical use.3.2 center attraction stationThe central suction station consists of a vacuum pump, a bacterial filter, a control cabinet, a dirt receiver and a vacuum buffer tank (a negative pressure tank). The vacuum pump must be in reserve and can be switched automatically.General medical vacuum pump has reciprocating vacuum pump, liquid ring (water ring) vacuum pump, oil lubricated sliding vane vacuum pump.: reciprocating vacuum pump: cheap and durable, but covers a large area, large noise, need cooling water, exhaust pipe must be installed muffler;: liquid ring vacuum pump: small size, small noise, but need to add recycled water. The system needs a water separator, and the ground must be equipped with a water tank.Oil lubricated sliding vane vacuum pump: it has the advantages of air cooling, low noise and little vibration. The internal one-way valve protects the suction system from contamination, and the oil mist separator protects the environment and reduces oil losses. Since the equipment is air cooled, the equipment room must be well ventilated.Auxiliary equipment of negative pressure suction system:: Double bacteria filter: prevent vacuum pump and vacuum tank from being polluted.: uninterrupted airflow replaceable filter: 2 interchangeable particulate filters.: dirt receiver: collects contaminated and liquid, protects the vacuum system to operate normally, does not interrupt the air current, may clean up the pollutant.: vacuum buffer tank: prevent frequent starting ofvacuum pump.3.3 technical requirements of negative pressure suction systemThe negative pressure of the suction system is not higher than 0.02MPa (150mmHg) in atmospheric environment, not less than 0.07MPa (525mmHg), and can be adjusted arbitrarily in this range.

The intake air is clean air outside, and the suction port must be far away from all kinds of air vent.5. other medical gases (N2O, CO2, N2) systems5.1 other medical gases (N2O, CO2 and N2) are supplied by air source station, and then fed to medical terminal after decompression by double channel bus.5.2 gas supply stationBecause N2O, CO2 and N2 use less gas, the gas source can be supplied by a steel cylinder. The gas station is made up of cylinder gas and busbar, and the cylinder gas is composed of two sets. The location of the small gas station can be closeto the gas point, such as the operation room, technical mezzanine and so on. The room should be ventilated.Three. Common parameters of medical gas1. oxygen: single nozzle calculation flow is 5 l/min, breathing machine calculation flow is 10~20 l/min, oxygen terminal pressure is 0.2~0.4MPa.Simultaneous use factor: the whole ward is 0.2-0.4, the horizontal dry tube is 0.4-0.5, and the branch pipe of each ward is 1.Negative pressure suction: the flow rate of the single nozzle is 0.25 l/s, and the negative pressure of the operation table is 0.75~1.0L/s, the attraction pressure is -300mmHg~-600mmHg.Simultaneous use factor: the whole ward is 0.2~0.3, the horizontal dry tube is 0.3~0.4, and the branch pipe of each ward is 1.Compressed air: single nozzle calculation flow is 20~100 l/min, pressure is 0.4~0.5 MPa.Two: single nitrogen oxide flow rate is less than or equal to 30 l/min, the pressure is less than or equal to 0.4MPa.Nitrogen: the flow rate of single nozzle is 10 l/min and the pressure is 0.8~0.9MPa.Carbon dioxide: single nozzle flow calculation is less than 10 l/min, the pressure is 0.4~0.5MPa.2. selection of common gas pipe diameterAE3Calculation formula of oxygen diameter:Style: d=0.0188D - pipe bore (m)V - gas flow rate (m/s)Q - the actual volume of flow (m3/h) of a gas under operating conditionsQ=Q2 - free volume flow (m3/h)T - gas working temperatureP - the absolute pressure (MPa) of the gas working stateThe maximum flow rate in the oxygen pipe shall not exceed the value in the following table:Oxygen working pressure(MPa) 0~0.1, 0.1~0.3, 0.3~0.6, 0.6~1.6, 1.6~3.5, >10Maximum oxygen flow rate(m/s) 20 or less 15121084Vacuum pipe diameter:Because the negative pressure pipeline is not easy and convenient to calculate accurately, it can be referenced by the empirical data of the following table:Suction pipe diameter estimation tablepipe diameter(mm) 152025324050Number of attractive mouths(a) 1221246284140Note: the coefficient of simultaneous use has been taken into account in the table. The diameter of the pipe can be directly measured by the number of nozzles in the design. There is no need to discount any more. But when the computer room is too far from the use place, should enlarge the caliber suitably.3. pipeline laying method in wardThe arrangement of medical gas in the hospital ward can be divided into vertical main pipe transmission, horizontal dry pipe distribution and horizontal main pipe transmission, and vertical dry pipe is distributed to two kinds. Vertical manifold delivery, horizontal dry pipe distribution, has the advantage that two relief boxes or gas valve boxes can be installed in the horizontal dry pipe to make the gas supply adequate and the end pressure stable. Can provide gas supply system operation or normal air pressure gauge for each nursing station, medical personnel, monitoring the dangerous signal alarm; convenient maintenance, less impact: as the center workstation terminal device set up maintenance switch, the system does not stop gas can be repaired. But initial investment costs are slightly higher.The vertical distribution system of horizontal main pipe has the initial investment, but it can not be layered management and maintenance. In the ward, the gas pipeline can be exposed pipes with adjustable groove, groove plate center height 1.45M, terminal and power source beds, special grounding, call and communication, lighting and other centralized combination in the bed, easy to use. The air terminal in operation room and resuscitation room is arranged by hanging and wall.The gas duct layout can be vertical wells in the pipeline (not allowed with the power line laying in the same tube wells), horizontal pipe can be arranged on the ceiling in the loose.4. selection and connection of pipesPipe：* the oxygen pipe material is stainless steel tube and deoxidized copper tube (copper tube for short).* galvanized steel pipe can be used to attract pipe material.
