These devices utilize a micro-pressure sensor to adaptively sense pressure changes, enabling pulsed oxygen supply. A person wears a nasal cannula to inhale oxygen. As the person inhales, the pressure sensor adaptively senses changes in respiratory pressure, supplying oxygen during inhalation and stopping during exhalation, thus meeting the pulsed oxygen supply and the person's actual oxygen needs.

[0022] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in conjunction with the utility model embodiment. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Embodiment 1

[0024] The embodiment discloses an integrated oxygen adjusting device for an oxygen supply machine, especially a civilian oxygen supply machine. Figure 1 、 Figure 2 As shown in the drawings, the integrated oxygen adjusting device comprises:

[0025] Integrated connector 1 is a four-way connector, comprising an air inlet connection port 11, a respiration detection connection port 12, a smart valve mounting cavity 14, and an oxygen outlet connection mounting hole 13. In this embodiment, to reduce the weight of the device, integrated connector 1 can be made of lightweight materials such as aluminum or plastic. The overall shape of integrated connector 1 can be cylindrical or square. Regardless of the shape, the core design is economical, lightweight, and compact. Air inlet connection port 11 is connected to the oxygen concentrator.

[0026] The smart valve 2 is mounted in the smart valve mounting cavity 14 and is used to open and close the air inlet connection port 11 and the oxygen outlet connector mounting hole 13. The smart valve 2 of this embodiment can be a solenoid valve or an electric valve. To reduce the size and weight of the device, a solenoid valve is preferred in this embodiment. The solenoid valve is threadedly fixed in the smart valve mounting cavity 14 and comprises an air inlet chamber 21, a valve body, and an exhaust chamber 22, in the order of airflow direction. The air inlet chamber 21 is connected to the air inlet connection port 11, and the exhaust chamber 22 is connected to the respiratory detection connection port 12 and the oxygen outlet connector mounting hole 13.

[0027] The oxygen outlet connector 3 is threadedly assembled or clamped in the oxygen outlet connector mounting hole 13 . In this embodiment, a filter cotton 4 is further provided in the oxygen outlet connector mounting hole 13 for filtering oxygen.

[0028] The respiratory monitoring unit is installed at the respiratory detection connection port 12. The respiratory monitoring unit of this embodiment can be a pressure sensor or a flow sensor, preferably a pressure sensor, and can be installed by installing a pipe at the respiratory detection connection port 12 and installing the pressure sensor on the pipe.

[0029] In this embodiment, the air inlet connector 11, the respiration detection connector 12, the smart valve mounting cavity 14, and the oxygen outlet connector mounting hole 13 are located on four sides of the integrated connector 1 to prevent interference. This design also reduces the size and weight of the integrated connector 1. Furthermore, the air inlet connector 11 and the respiration detection connector 12 utilize quick connectors, such as bamboo-shaped connectors with anti-detachment features.

[0030] In the initial state, the solenoid valve is closed. When the user puts on the oxygen tube and inhales, the air pressure in the integrated connector 1 becomes smaller due to the closure of the solenoid valve. The pressure sensor detects the pressure change and sends a control signal to the controller. The controller controls the solenoid valve to open. At this time, oxygen enters the exhaust chamber 22 of the solenoid valve and then enters the oxygen tube from the oxygen outlet connector mounting hole 13. If the user continues to inhale oxygen and the pressure continues to change regularly, the solenoid valve will always remain open. When the user stops using it, the pressure sensor detects that the pressure in the integrated connector 1 or the pipeline has not changed for a set time, and the controller controls the solenoid valve to close. The setting time can be 1s.

[0031] This embodiment uses an integrated joint 1 to open four interfaces, and assembles the oxygen generator, solenoid valve, detection unit, and oxygen outlet joint 3 into a whole in the form of a four-way valve, especially the bamboo joint that is convenient for pipe connection and the threaded joint that is easy to disassemble, so that the assembly and disassembly of each part can be easily operated. The use of the integrated joint 1 for assembly can greatly reduce the volume and weight and improve portability.

[0032] Example 2

[0033] Based on the integrated oxygen regulating device provided in Example 1, this embodiment provides an oxygen supply device, including an oxygen production unit and a controller. The oxygen production unit is connected to the air inlet connection port 11 through a pipeline, and the controller controls the opening and closing of the solenoid valve according to the signal from the pressure sensor.

[0034] Based on the integrated joint 1, the oxygen supply machine of this embodiment can be disassembled and packed when not in use, which is convenient for carrying. When in use, it is also convenient and quick to assemble, and is suitable for civilian use.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
