Use
Oxygen cylinders can be taken home and used by yourself. You can use it at home if you know how to regulate the oxygen flow rate, or if you use an oxygen cylinder, regulate the oxygen flow rate, two liters per minute, and then make sure to blow dust off the cylinder before each oxygen intake.
Changes in hospital oxygen supply
The traditional way of supplying oxygen in hospitals is to push the cylinder oxygen to the patient's bedside, connect the pressure reducing valve and oxygen wetting metering device to the cylinder, and then send it to the patient's nasal cavity through the rubber tube or plastic tube.Since the late 80's and early 90's, the major hospitals in large cities gradually embarked on the road of centralized supply of oxygen in hospitals. Road. The manifold with 10-20 oxygen cylinders is placed in the oxygen station, and it is transported to the terminals of the wards on each floor through the pipeline network system after the second level of pressure reduction. The terminal is installed with oxygen fast socket, after inserting the oxygen inhaler in the socket, the oxygen will flow out from the fast socket after humidification and pressure regulation, and then pass into the patient's nose by the nasal oxygen tube, or directly into the ventilator and other oxygen equipment.
Currently, the centralized oxygen supply method has been widely promoted to the township central hospitals, basically abandoning the oxygen cylinders to be carried to the beds on each floor of the decentralized oxygen supply method.
Centralized oxygen supply method of oxygen source requirements
Centralized oxygen supply oxygen source requirements for medical oxygen, generally by three ways to provide:
(1) cylinders of oxygen: bottled oxygen from medical oxygen supply through the oxygen sink.
(2) liquid oxygen: with the help of certain devices to get -183 ℃ state of the liquid oxygen, through the liquid oxygen storage tank and then gasification, decompression, pressure stabilization, to provide medical oxygen.
(3) medical molecular sieve oxygen: air as raw material, zeolite molecular sieve as adsorbent, with pressure change adsorption method (PSA) to produce oxygen concentration of 93 + 3% of oxygen-rich air.
Precautions for the use of household oxygen cylinders
(1) oxygen cylinders and other flammable cylinders, oil and grease and flammable and explosive substances should be stored separately;
(2) storage of high-pressure oxygen cylinders should be screwed tightly the cap, placed in a neatly, leaving the channel, to be secured;
(3) oxygen cylinders storage should be with high temperature, (3) Oxygen cylinder storage room should be kept at a distance of more than 10m from the place of high temperature and open fire;
(4) Oxygen cylinders should be placed upright and fixed when transporting, and their height should not be more than the carriages' groove gangs;
(5) It is strictly prohibited to transfer high-pressure cylinders with bicycles, forklift trucks or lifting equipments;
(6) Oxygen cylinders should be equipped with anti-vibration rings and safety caps. Handling and use of impact is strictly prohibited;
(7) Oxygen cylinder valve shall not be adhered to the grease, dust and soil. Do not use tools with grease, gloves or tool clothing to contact the oxygen cylinder valve.
(8) Oxygen cylinders shall not be exposed to strong sunlight, summer open-air work, should be set up sunscreen, shed.
(9) The distance between the oxygen cylinder and the welding torch, cutting torch, furnace and other open flames should be not less than 10m, and the distance from the acetylene cylinder should not be less than 5.
