Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to a safety connection structure of an oxygen concentrator. Background Art

[0002] An oxygen concentrator is a device that produces oxygen. It physically separates oxygen from air to produce high-concentration oxygen for use by those who require it. Medical oxygen concentrators typically have a high oxygen flow rate and concentration, capable of providing oxygen to multiple patients simultaneously. Some medical oxygen concentrators are also equipped with oxygen monitoring and alarm systems to ensure a safe and reliable oxygen supply.

[0003] Existing oxygen concentrators usually connect the trachea to the oxygen outlet. However, the oxygen concentrator can adjust the oxygen flow rate. When the oxygen flow rate is too high, the connection between the trachea and the oxygen concentrator can easily loosen, resulting in air leakage. In addition, people walking around the oxygen concentrator may accidentally touch the trachea, causing it to fall off the oxygen concentrator, which may put the patient's life in danger. Utility Model Content

The fastening mechanism is used to fix the air pipe to the air outlet pipe. The fastening mechanism includes a plurality of clamping blocks, the plurality of clamping blocks are distributed in a circular array along the center of the air outlet pipe, and each of the clamping blocks slides on the oxygen concentrator along the radial direction of the air outlet pipe. The structure also includes a limit block, the limit block is used to limit the movement of each clamping block so that the clamping block abuts against the air pipe.

[0007] Furthermore, the clamping block includes a slider slidably connected to the oxygen concentrator, and an arc-shaped plate is fixedly provided on the slider, and an external thread is provided on the outer side surface of the arc-shaped plate.

[0008] Furthermore, the limit block includes a hollow cylinder, and an internal thread matching the external thread is provided on the inner side of the hollow cylinder. When the internal thread is connected to the external thread, the hollow cylinder enables the arc block to remain in contact with the trachea.

[0009] Furthermore, a first oblique block is provided at the end of the arc-shaped plate, and a second oblique block adapted to the first oblique block is provided at the end of the hollow cylinder, and the second oblique block is provided in a ring shape.
