Problems solved by technology

[0002] At present, conventional ventilators and anesthesia machines used in operations all use oxygen cylinders to supply oxygen. Especially in field medical occasions, the ventilator uses a large amount of oxygen, and the oxygen storage capacity of oxygen cylinders is limited, so it is necessary to frequently replace the cylinders to supplement oxygen. It is necessary to ensure that the oxygen source cannot be interrupted, and the requirements for transport capacity are high. In the field environment, once the oxygen supply cannot be guaranteed, the operation cannot be performed; the oxygen storage pressure of the oxygen cylinder is relatively high (usually the pressure of a full bottle of oxygen is about 12MPa), and it is a pressure vessel. , there is a security risk in storing

[0003] The utility model with the authorized announcement number CN2687099Y discloses a complete set of oxygen production equipment integrating oxygen production, oxygen supply and oxygen storage, which includes a molecular sieve oxygen production host, which is connected to a buffer filter through an output pipeline The outlet of the filter is connected to the oxygen storage tank for oxygen supply through the oxygen booster. Although the equipment can realize continuous and uninterrupted oxygen production and oxygen storage, it has the following disadvantages: (1) the equipment has two main oxygen generators. A total of 11.5m of oxygen 3 / d (about 8L / min), the oxygen production cannot directly meet the use of the ventilator (generally the required oxygen volume is 10L / min), it is necessary to work in advance and store a certain amount of oxygen in the oxygen storage tank; (2) due to oxygen production The oxygen output of the main engine is low, and it cannot be used immediately to meet the use of the ventilator in real time. Therefore, the volume of the oxygen storage tank must be designed with a larger volume, and a certain amount of oxygen must be reserved in advance to meet the oxygen requirements of the ventilator. The use of fixed medical and health institutions is suitable, but it is inconvenient to move and carry after oxygen storage, and there is also certain danger. Therefore, the utility model of CN2687099Y is not suitable for use in places where the field is carried at any time; (3) there is no The working principle and working process of the oxygen booster to achieve oxygen boosting are described in detail, and no specific measures and methods are clearly proposed to solve the key problems (such as oxygen leakage, etc.)
