How to charge medical oxygen?

1. At present, there is no fixed medical oxygenation point in China. If you need to inflate, you can try to contact the local hospital. Second, the use of the oxygen bag: First, fill the oxygen bag with oxygen, so that the inflation pressure is 25Kpa. Connect the rubber catheter with one end of the oxygen inhalation tube with a plug, and insert the other end into the nostril. The amount of oxygen can be adjusted by plastic check valve. When the pressure in the bag is too low, some heavy objects can be pressed out of the bag to increase the pressure in the bag. Three. Precautions for using oxygen bag: 1. The oxygenation pressure shall not exceed 25Kpa to prevent the oxygen bag from bursting. 2, should avoid direct contact with acid, alkali and oil and excessive extrusion. 3. Don't shine in strong sunlight during storage or when stopping the machine after oxygenation. 4, can't use sharp objects contact oxygen bag, so as not to scratch the oxygen bag. 4. Storage method of oxygen bag: When the oxygen bag needs to be stopped after filling, please turn off the switch or tie the pipeline and put it in a cool place. Avoid being in the sun or in a place where the temperature is too high, and avoid contact with chemicals. Store in a dry and ventilated place, pay attention to moisture.

. 1.Before June, 2005 10, our hospital used the central oxygen supply station for daily "medical oxygen" (hereinafter referred to as "medical oxygen"), but all of them were "bottled gas medical oxygen", with an average of more than 65 bottles per day, and the monthly payment often exceeded 56,000 yuan. On the premise of "ensuring safety, reducing costs, improving efficiency and reducing costs", the project of "purchasing medical liquid oxygen to reduce the cost of medical oxygen" was launched in May 2004.

The second is the demonstration of changing bottled oxygen into liquid oxygen in the central oxygen supply station.

1. Liquid oxygen has rich sources. Liquid oxygen is rich in raw materials, and there are manufacturers, distributors and transportation enterprises in Henan Province and Zhengzhou City.

2. Safe and reliable storage and use. Many enterprises in Henan Province and Zhengzhou City have already used it. The process flow is simple: liquid oxygen storage tank-vaporizer-oxygen supply pipeline system. Although the storage tank is a low-temperature pressure vessel, it has been produced by many domestic manufacturers, and the corresponding national safety standards are relatively complete, so it can be used with confidence.

3. The location is feasible. According to the national pharmaceutical industry standard (YY/T 0187-94) 4.1.2.2, the distance between outdoor liquid oxygen tanks and offices, wards, public places and busy roads should be more than 7.5 m. There is no special provision in the Code for Fire Protection Design of Buildings [6], and the space of our existing site is completely suitable.

In accordance with the norms, pay close attention to implementation.

1. equipment bidding. According to the financial system, national bidding law and other laws and regulations and the specific requirements of sunshine project construction, on May 9, 2004, two "liquid oxygen tanks" (V=5.0 m3, P=0.8MPa, one for use and one for standby) were invited for bidding. Considering the price, construction period and after-sales service of 338,000 yuan, 347,000 yuan and 368,000 yuan, we chose "334,000 yuan" (preferential price of 338,000 yuan) to win the bid. On June 22, 2004, 1 1, it was accepted as a whole after completion and put into use at the same time.

2. Buy liquid oxygen. When I was preparing to buy liquid oxygen for canning, I suddenly thought of whether "liquid oxygen" was "medical oxygen". Right here, this discussion is very intense. If it is not clear, it will be in danger of being labeled as "industrial oxygen flowing into big hospitals". After several months of patient waiting, it was finally made clear in the document of the national letter (No.484 [2005]) on June 9, 2005 that "medical liquid oxygen, like medical gaseous oxygen, must be approved and registered by the Food and Drug Administration before it can be produced and sold", which made Henan (Henan note [

3. Bidding procurement. Since "medical liquid oxygen" is a medicine, it is necessary to bid in accordance with the provisions of "medicine". In addition to the price factor, we should also pay attention to whether the producer of this product has a drug production license, whether it has obtained a national GMP certificate, and whether it meets the production, operation and transportation requirements stipulated in the Regulations on the Safety Management of Hazardous Chemicals (Order No.344 of the State Council). Only comprehensive consideration can ensure clinical use and reassure patients. After bidding, we shop around and choose a fully qualified "medical liquid oxygen" production enterprise in this city.
