Anesthesia breathing tube connection and fixed structure

Technical field

The utility model belongs to the technical field of medical machinery, and in particular relates to an anesthesia breathing pipeline connection and fixation structure.

Background technique

Anesthesia breathing circuit refers to connecting the gas output port of the anesthesia machine and the patient's breathing pipe to form a loop. Fresh gas and anesthetics are input into the patient's respiratory tract through the anesthesia breathing pipe, and the patient's exhaled gas is discharged to in vitro.

The existing anesthesia machine breathing pipeline is connected to the anesthesia mask connector and the anesthesia machine connector through a hose. Generally, the two ends of the hose have hard plastic connectors. The plastic connectors are connected to the anesthesia mask connector and the anesthesia machine connector through friction. Tight-fitting connection, but due to the inevitable pulling of the hose during anesthesia, it is easy to cause the connection between the hose and the anesthesia mask or anesthesia machine to fall off. At the same time, due to the distance problem, the connection between hoses is often used, and the connection between the two is also easy to fall off.

Further, a fixed ring is set on the peripheral side of the connecting cylinder outside the two ring sliding plates. The fixed ring has N chute openings corresponding to the rectangular grooves. The rectangular groove is connected to the connecting tube. When the components are connected, the U-shaped plate passes through the rectangular slot.

Further, N=5.

Furthermore, a plurality of extension handles extending in the radial direction are also provided on the outer peripheral surface of the annular sliding plate.

The utility model has the following beneficial effects:

1. This utility model stretches the elastic spring by pulling a circular slide plate, and then puts the barrel of the pipe fixing member outside the connecting barrel, and passes the U-shaped plate through the chute opening of the fixed ring. Make the V-shaped plate enter the interior of the U-shaped plate. At this time, pull the two second hinge plates parallel to the V-shaped plate. Release the ring slide. Under the action of the elastic spring, the V-shaped plate moves close to the rectangular frame, and the second hinge plate moves closer to the rectangular frame. The plate is pressed between the V-shaped plate and the outer wall of the rectangular frame, which can be suitable for the modification of the existing anesthesia ventilator. It only needs to fix the tube body fixing parts of this embodiment at the interfaces to realize the connection between the hose and the rectangular frame. The quick connection of the machine and the quick replacement of the hose make it easy to disinfect the replaced hose. After the pipeline is connected, it is not easy for the tube body to detach due to the patient's movements and accidental pulling.
