The utility model relates to an oxygen self-rescuer. The oxygen self-rescuer comprises a breathing system and an absorption assembly. The breathing system comprises an inspiration pipe, an expiration pipe, a breathing air bag and an oxygen bottle, one end of the inspiration pipe is communicated with the face of the human body, and the other end of the inspiration pipe is communicated with the breathing air bag. The absorption assembly is used for absorbing carbon dioxide and communicates with the breathing airbag. Wherein the other end of the expiration pipe is contained in the absorption assembly, and a pressing air bag is further arranged on the breathing air bag and used for promoting air in the breathing air bag to be diffused into the absorption assembly. According to the technical scheme, gas exhaled by a human body can directly enter the absorption assembly, and the carbon dioxide absorption efficiency of the absorption assembly is higher. The breathing air bag further contains a part of carbon dioxide which is not absorbed by the absorption assembly, in order to increase the flow speed of air in the breathing air bag, a user can use the pressing air bag, and the air in the breathing air bag can be diffused into the absorption assembly more easily.

The invention discloses a breathing machine pipeline, and belongs to the technical field of breathing machines, when the breathing machine pipeline is used, an expiration pipe and an inspiration pipe are communicated to the breathing machine, the other ends of the expiration pipe and the inspiration pipe are connected to two branch pipes of a Y-shaped joint, and an outer cup of a water collecting cup is mounted on a cup cover. When the water collecting cup is used and bumps to a certain degree, due to the fact that the hinge mechanism is arranged between the top end of the inner cup and the cup cover and the self-weight mechanism is arranged at the bottom of the outer wall of the inner cup, the hinge mechanism can enable the inner cup to rotate to a certain degree in the horizontal direction, and meanwhile the inner cup can be vertically and downwards arranged all the time through matched use of the self-weight mechanism.
