[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0021] Removable connections use screws, splines, wedge pins, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened. (2) Non-removable connections mainly refer to welding, riveting, and tenoning. Since forging, sawing, or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical testing, and remedial measures (such as calibration, polishing, etc.).

[0022] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded part of the connected parts).

[0023] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0024] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0025] Beneficial effects of the present disclosure:

[0026] When the endotracheal tube connector and the ventilator bellows connector are connected to the connecting pipe, they can be fixed at the connection to prevent the endotracheal tube connector from being separated from the ventilator bellows connector. BRIEF DESCRIPTION OF THE DRAWINGS

The breathing pipe with heating function also includes a heating wire and a power adapter. Disposable or reusable.

[0042] It should be noted that the structures of the connecting tube body 1, the endotracheal tube connector 2 and the ventilator bellows connector 3 in the present application are existing structures, which are common instruments currently used in hospitals. The first fixing component 4 and the second fixing component 5 in the present application are structures added to the technology of the existing structure, which can fix the endotracheal tube connector 2, the ventilator bellows connector 3 and the connecting tube body 1 to prevent them from detaching.

[0043] In one embodiment of the utility model, the connecting pipe body 1 includes two vertically arranged first connecting pipes 11 and second connecting pipes 12 fixedly connected, a fixing ring 13 is fixedly connected to the first connecting pipe 11, a connecting sleeve 14 is sleeved on the outer side of the first connecting pipe 11, and the connecting sleeve 14 is fixedly connected to the fixing ring 13.

[0044] In one embodiment of the utility model, the tracheal tube connector 2 includes a plug connector 21 plugged into the first connecting tube 11, and two ear plates 22 are symmetrically fixedly connected to the circumference of the plug connector 21. When the tracheal tube connector 2 is connected to the connecting tube body 1, the plug connector 21 is aligned with the first connecting tube 11 and inserted into the inner side of the first connecting tube 11 to achieve connection, but this connection method is easy to fall off.

[0045] In one embodiment of the present invention, the ventilator bellows connector 3 includes a first sleeve connector 31 sleeved on the outside of the second connecting pipe 12, a second sleeve connector 32 sleeved on the outside of the first sleeve connector 31, and a fixed connection between the outer ends of the first sleeve connector 31 and the second sleeve connector 32. When the ventilator bellows connector 3 is connected to the connecting pipe body 1, the second connecting pipe 12 is aligned with the first sleeve connector 31 and inserted into the inner side of the first sleeve connector 31 to achieve connection, but this connection method is easy to fall off.
