Description

Technical Field

[0001] The utility model relates to a condensation cup drainage mechanism for a respirator, which is used in the field of respirator components. Background Art

[0002] The ventilator is equipped with a condensation cup on the ventilator connecting pipeline to condense the water vapor exhaled by a person into water at the condensation cup position to prevent it from flowing into the ventilator and affecting the operation of the ventilator.

[0003] After using the ventilator for a period of time, the condensed water in the condensation cup needs to be drained in time to prevent the water level from being too high and causing water backflow. The conventional way to drain is to dismantle the hanging condensation cup and pour out the condensed water. However, this method will cause the condensed water containing the virus to be exposed to the air in the environment of respiratory virus transmission, causing aerogel contamination.

[0004] Currently, there is no suitable method or device to remove the water in the condensation cup in time. Summary of the invention

[0005] The invention provides a condensation cup drainage mechanism for a respirator, which solves the problem of discharging condensed water without disassembling the condensation cup.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] The utility model discloses a ventilator condensation cup drainage mechanism, wherein the lower part of the condensation cup is provided with a drainage port, the drainage port is connected to a drainage short pipe, a water valve switch is provided on the drainage short pipe, and the lower end of the water valve switch is a joint.

[0008] Preferably, a drainage hose is connected below the joint, the lower end of the drainage hose is connected to a soft drainage bag, and the drainage bag is provided with an anti-backflow structure at the liquid inlet.

[0009] Preferably, a drainage hose is connected below the joint, and the lower end of the drainage hose is connected to a hard drainage bottle. The drainage bottle does not deform when held normally, and the drainage hose passes into the drainage bottle.

[0010] Preferably, the drainage hose is provided with a rubber water bag with micropores in the drainage bottle, and a drainage capillary is provided outside the rubber water bag with micropores, and the lower inner hole of the drainage capillary is squeezed and fitted.

[0011] Preferably, the joint is a conical tube, and a closing cap is added to the conical tube to close the outer port of the joint.

[0012] The advantages of the utility model are: the utility model can effectively discharge the condensed water in the condensation cup to avoid backflow caused by too high water level; it solves the aerogel contamination problem caused by drainage in the disassembly mode, and can be promoted and used in current hospitals to reduce the risk of transmission of respiratory viruses; the drainage structure can be both a soft bag and a hard screen, which is suitable for the current treatment environment.
