Description

External screw-cap water collection device for ventilator pipelines

Technical field

The invention belongs to the field of medical equipment, and specifically relates to an external screw-cap type water collection device for a ventilator pipeline.

Background technique

When a patient is seriously ill and unable to breathe on his own, a ventilator is needed to assist or force the patient to breathe to maintain basic vital signs. In addition to the basic air pipe, the ventilator pipeline also includes Y-tube components and water collection cup components. Both ends of the Y-shaped tube assembly are connected to the air pipeline, and the third end is connected to the water collecting cup assembly. The water collection cup assembly is mainly used to absorb the water that is liquefied from hot and humid gases when the patient breathes. Because its capacity is usually designed to be small, medical staff need to remove the water collection cup assembly before the water collection cup assembly is full and dump the water inside. Continue to connect the Y-shaped pipe assembly for use, or replace the new water collection cup assembly and connect it to the Y-shaped pipe assembly for use. The frequency of replacement is usually 3-4 hours/time. During the above replacement process, after the water collecting cup assembly is removed, the connection between the Y-shaped pipe assembly and the water collecting cup assembly is left open. In the existing technology, corresponding self-sealing measures are adopted for the Y-shaped tube assembly, such as a gravity self-sealing structure, so that when the water collecting cup assembly is removed, the lower end of the Y-shaped tube assembly is self-sealed to prevent bacteria in the external environment from being leaked into the Y-shaped tube assembly. The tube component enters the trachea and is inhaled by the patient, causing the patient's infection to worsen; it also avoids infection by germs contained in the patient's exhaled air (for example, patients in ICU are usually in serious condition, and their exhaled air also contains a large number of germs). Replace the water cup of medical staff. However, in the prior art, there is no effective measure to prevent the mouth of the water collecting cup assembly from being sealed after the water collecting cup assembly is replaced. If the water collection cup assembly is not sealed, the condensed water inside it will also carry a large number of germs. Spilling or evaporation of the condensed water will cause medical staff to be exposed to high-risk germs in the working environment, causing a huge gap between medical staff and patients. risk of cross-infection.

Therefore, a kind of collector is designed that can close the Y-shaped pipe assembly and the water collecting cup assembly at the same time when disassembling and replacing the water collecting cup assembly.
