Embodiment 1

[0040] Embodiment 1: the implementation steps are as follows:

[0041] 1. The system is connected to the home medical oxygen generator;

[0042] 2. Oxygen concentration monitoring: monitor the oxygen concentration supplied by the home medical oxygen generator, and this parameter is used as a signal for system startup. When the oxygen concentration of the home medical oxygen concentrator reaches the specified requirements, the system will start the oxygen pressurization process;

[0043] 3. Oxygen pressurization process: After the system starts the oxygen pressurization process, the multi-stage series-connected plunger-type oxygen pressurization device starts to work, pressurizes the oxygen supplied by the gas source at 0.05-0.2MPa to 10-30MPa, and waits for the oxygen to be swept away. blowing process;

[0044] 4. Oxygen sweeping process: Fill the oxygen cylinder with pressurized high-pressure oxygen, and when the oxygen pressure in the portable bottle reaches the preset val...

Embodiment 2

[0047] Embodiment 2: the implementation steps are as follows:

[0048] 1. The system is connected to the home medical oxygen generator;

[0049] 2. Oxygen concentration monitoring: monitor the oxygen concentration supplied by the home medical oxygen generator, and this parameter is used as a signal for system startup. When the oxygen concentration of the home medical oxygen concentrator reaches the specified requirements, the system will start the oxygen pressurization process;

[0050] 3. Oxygen pressurization process: After the system starts the oxygen pressurization process, the multi-stage series-connected plunger-type oxygen pressurization device starts to work, pressurizes the 0.05-0.2MPa oxygen supplied by the gas source to 10-30MPa, and waits for the high-pressure storage Oxygen process;

[0051] 4. High-pressure oxygen storage process: store the prepared high-pressure oxygen in a high-pressure oxygen storage tank. Pressure detection The high-pressure oxygen storage...

Embodiment 3

[0055] Embodiment 3: the implementation steps are as follows:

[0056] 1. The system is connected to the home medical oxygen generator;

[0057] 2. Oxygen concentration monitoring: monitor the oxygen concentration supplied by the home medical oxygen generator, and this parameter is used as a signal for system startup. When the oxygen concentration of the home medical oxygen generator reaches the specified requirements, the system will start the direct oxygen supply process;

[0058] 3. Direct oxygen supply process: When the system detects that the oxygen concentration reaches the preset value, it will directly supply oxygen to the person in need of oxygen through the oxygen supply tube.

Abstract

The invention discloses a portable oxygen bottle pressurizing and filling system and method. The portable oxygen bottle pressurizing and filling system comprises a low-pressure oxygen connector, an oxygen pressurizing device, a pressure detector, a portable oxygen bottle, a sweeping and blowing device and an oxygen concentration monitoring device, wherein one end of the oxygen pressurizing device is connected with an oxygen source through the low-pressure oxygen connector, and the other end of the oxygen pressurizing device is connected with an input port of the sweeping and blowing device and the pressure detector; two output ports of the sweeping and blowing device are respectively connected with the portable oxygen bottle and the oxygen concentration monitoring device; and the oxygen concentration monitoring device is connected to the output end of the low-pressure oxygen connector. The portable oxygen bottle pressurizing and filling system is small in size and can be used in various scenes such as hospitals, families and outdoor carrying, and a certain specific oxygen source is not specified. In addition, the oxygen filled into the portable oxygen bottle through pressurization of the system can ensure that the oxygen concentration reaches the standard. According to the system, the technical limitation and the cost of oxygen filling are reduced to a great extent.

Description

technical field [0001] The invention relates to the technical field of oxygen filling, in particular to a pressurized filling system and method for a portable oxygen bottle. Background technique [0002] Oxygen is essential to humans and all living things. Oxygen supply equipment is a must-have for oxygen-depleted areas such as plateaus and patients who need oxygen. Portable oxygen cylinders are ideal oxygen supply equipment for hospitals, first aid stations, nursing homes, home care, field ambulance, personal health care and various hypoxic environments, especially for outdoor sports in hypoxic areas, such as plateau soldiers and mountaineers etc., and the going out of the aerobic crowd provides a solution. However, the filling of portable oxygen cylinders is restricted by equipment, site, cost, technology and other conditions, and it still needs to rely on professional institutions and equipment to complete. [0003] A movable oxygen filling device is disclosed in the p...
