How to use oxygen in the hospital

At present, there is no fixed medical oxygen filling point in the country, you can try to contact the local hospital if you need to inflate. Second, the use of oxygen bag: first of all, the oxygen bag will be filled with oxygen, so that the inflatable pressure in 25Kpa. rubber catheter and oxygen tube with a plug on one end of the connection, the other end into the nostrils. The size of oxygen absorption can be adjusted by the plastic stop valve. When the pressure inside the bag is too low, you can press some heavy objects outside the bag body, which can make the pressure inside the bag increase. Third, the use of oxygen bag precautions: 1, oxygen pressure shall not exceed 25Kpa, in order to prevent rupture of the oxygen bag.　　2, should avoid direct contact with acid, alkali, oil and excessive force extrusion.　　3、Don't irradiate it under strong sunlight during storage or deactivation after filling it with oxygen.　　4, can not use sharp objects to contact the oxygen bag, so as not to scratch the oxygen bag. Storage method of the oxygen bag: When the oxygen bag is not in use after filling, please turn off the switch or tie the pipeline tightly and put it in a cool place, avoid putting it in the sunlight or the place where the temperature is too high, and it can not contact with chemical substances. Keep it in a dry and ventilated place, and pay attention to moisture-proof.

. First, our hospital in October 2005, the hospital's daily "medical oxygen" (hereinafter referred to as "medical oxygen") with the use of a central oxygen supply station, but still all "bottled gas medical oxygen "The average number of bottles per day is more than 65, and the monthly payment often exceeds 56,000 yuan. In the "ensure safety, reduce costs, improve efficiency, reduce expenditure" under the premise, from May 2004 to start "procurement of medical liquid oxygen, reduce the cost of medical oxygen" project work.

Second, the central oxygen station bottled oxygen for liquid oxygen program argumentation

1. Liquid oxygen source is rich. Liquid oxygen raw materials are rich and sufficient, Henan Province, Zhengzhou City and other places have production, sales manufacturers and transportation enterprises.

2. Storage and use of safe and reliable. Many enterprises in Henan Province and Zhengzhou City have already used it. The process is simple: liquid oxygen storage tank - vaporizer - oxygen supply piping system. Although the storage tank is a low-temperature pressure vessel, but the country has a lot of manufacturers and the corresponding national safety standards are more complete, can be used safely.

3. Site feasibility. According to the "building design fire code" [6] in no special provisions and the national pharmaceutical industry standards (YY/T 0187-94) 4.1.2.2 on "outdoor liquid oxygen tanks and offices, wards, public **** places and busy roads should be more than 7.5 m" of the provisions of our The space of the existing site is perfectly suitable.

In accordance with the norms, to grasp the implementation

1. equipment bidding. According to the financial system and the state "bidding law" and other provisions and the construction of the specific requirements of the Sunshine Project, on May 9, 2004 carried out two sets of "liquid oxygen tanks" (V = 5.0 m3, P = 0.8 MPa, a use and a reserve) manufacturing and installation of the construction drawings for bidding. The price of 338,000 yuan, 347,000 yuan, 368,000 yuan and the duration, after-sales service and other conditions were considered and selected "334,000 yuan" (338,000 yuan of the preferential price) won the bid. On November 22, 2004, the overall post-completion acceptance and simultaneous delivery.

2. Purchase of liquid oxygen. When we were about to purchase liquid oxygen for filling tanks, the principle of whether "liquid oxygen" is "medical oxygen" suddenly came up. In the meantime, this discussion is very intense, the slightest mistake, there will be "industrial oxygen into the big hospitals" hat was deducted the danger. After months of patient anticipation, finally on October 9, 2005 by the "State Food and Drug Administration document" (State Food and Drug Administration Note [2005] No. 484) in a clear "medical liquid oxygen and medical gaseous oxygen, must be approved by the Food and Drug Administration registration before production and sale" of the provisions of. Only to make the "Henan Province Food and Drug Administration document" (Yu Food and Drug Administration Note [2005] No. 298) has a positive direction.

3. Bidding procurement. Since the "medical liquid oxygen" is a drug, it must be in accordance with the provisions of the "drug" bidding, in addition to the first consideration of the price factor, but also must pay attention to the producer of the product is whether the "Drug Production License" and whether to obtain the national "Drugs GMP certificate" and whether to comply with the "Regulations on the Safe Management of Dangerous Chemicals" (State Council Decree No. 344) on the production, operation, transportation and other conditions. Only through comprehensive consideration can clinical use be assured and patients feel at ease. After bidding, comparison of goods, comprehensive weighing, near the city to choose a fully qualified "medical liquid oxygen" manufacturer.
