Description

Technical Field

[0001] The utility model relates to a medical appliance, in particular to a condensed water discharge structure of an extension tube. Background Art

[0002] A ventilator is a device that can replace, control or change a person's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory work consumption, and save heart reserve capacity. During the clinical application of a ventilator, a large amount of condensed water will be generated in the pipeline. This is because the gas heated by the ventilator humidifier and the gas exhaled by the patient are often higher than the room temperature, so part of the gas is condensed in the pipeline. This humidified environment is easy for bacteria to colonize. Moreover, the condensed water with bacteria in the ventilator pipeline flows back into the patient's airway, which can easily lead to the occurrence of ventilator-associated pneumonia (VAP).

[0003] The Chinese utility model patent CN213407340U announced on June 11, 2021 discloses a new funnel-type ventilator condensate anti-reflux device. The funnel-type water collecting and conveying device adopted is composed of a cylindrical interface section with an internal thread on the upper part of the funnel body and a straight pipe section on the lower part. The cylindrical interface section with an internal thread on the upper part of the funnel-type water collecting and conveying device is engaged with the external joint of the ventilator condensate storage tank, and a check valve is installed at the lower part of the external joint of the ventilator condensate storage tank, and a water level control switch valve is installed at the straight pipe section at the bottom of the funnel-type water collecting and conveying device, and the water outlet port of the water level control switch valve is equipped with a water supply pipe connected to the anti-reflux drainage bag. Utility Model Content

[0004] The purpose of the utility model is to provide a condensate discharge structure for an extension tube. When the gas flows from the front tube section of the extension tube to the rear tube section, the vertical plate can block the condensate from entering the rear tube section interface from the front tube section interface along with the airflow, and the condensate can smoothly flow downward along the side wall of the funnel groove from the discharge port into the liquid storage container, thereby preventing the condensate from nourishing bacteria in the extension tube and causing the occurrence of ventilator-associated pneumonia.

[0007] Compared with the prior art, the extended pipe condensate discharge structure using the above technical solution has the following beneficial effects:

[0008] By adopting the condensate discharge structure of the extension tube of the utility model, when the gas flows from the front tube to the rear tube of the extension tube, the vertical plate can prevent the condensate from entering the rear tube interface from the front tube interface along with the airflow, and the condensate will adhere to the surface of the vertical plate and fall downward into the funnel groove; the funnel groove plays a transitional role, so that the condensate can smoothly flow downward from the discharge port into the liquid storage container along the side wall of the funnel groove, thereby preventing the condensate from nourishing bacteria in the extension tube and causing the occurrence of ventilator-associated pneumonia.

The plugging core can prevent gas-liquid backflow and prevent bacteria from entering the patient's body from the drain port through the extension tube.

[0014] Preferably, a hanging rope is provided at the upper end of the liquid collector, and both ends of the hanging rope are respectively threadedly connected to the upper end of the liquid collector.
