Description

Technical Field

[0001] The present invention belongs to the technical field of ventilators, and in particular relates to a novel ventilator pipeline and a ventilator thereof. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used for respiratory failure caused by various causes, as well as for anesthesia and respiratory management during major surgery, respiratory support therapy, and emergency resuscitation. They hold a crucial position in modern medicine. Ventilators are vital medical devices that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] Disposable ventilator tubing is a specialized tubing for medical ventilators. Due to the thin tube wall, condensation easily forms in the tubing. In order to slow the growth of bacteria in the tubing and reduce the risk of infection for patients, the condensation in the tubing needs to be promptly drained. Currently, a water collection cup is provided on the disposable ventilator tubing. In clinical practice, medical staff generally collect condensation in the water collection cup every 30-120 minutes. This completely manual operation method not only increases the workload of medical staff, but also makes it difficult to remove condensation attached to the wall of the disposable ventilator tubing, resulting in a poorly maintained dry respiratory environment for patients, posing a potential health hazard.

[0004] To this end, the patent document with publication number CN214970767U discloses a ventilator pipeline drainage device and a disposable ventilator pipeline, wherein the ventilator pipeline drainage device includes a water collection cup and a water collection cup three-way joint, the water collection cup three-way joint includes an air inlet joint, an air outlet joint, and a drain joint for draining condensed water into the water collection cup, the air inlet joint and the air outlet joint are connected to form an air transmission channel, a vibration device is installed on the air inlet joint or the air outlet joint, and a drain pipe is provided at the bottom of the water collection cup. By providing the vibration device, the condensed water attached to the wall of the disposable ventilator pipeline can be shaken into the water collection cup, thereby ensuring that the pipeline is dry and providing the patient with a healthy breathing environment; and by providing the drain pipe, the water collection cup can be led out to a larger container or a centralized treatment device, which not only reduces the workload of medical staff, but also better ensures the dryness of the disposable ventilator pipeline and avoids the breeding of bacteria.

[0005] However, this type of ventilator circuit still has some shortcomings. First, it does not have an anti-backflow tube to prevent patients from accidentally inhaling the water vapor produced by condensed water; second, it cannot quickly transfer the condensed water.

An air inlet end is provided at the upper end of one side of the upper cavity, and an air delivery end is provided at the other side end of the upper cavity. Upper baffles and lower baffles are staggered in the area of ​​the upper cavity between the air inlet end and the air delivery end, a drainage end is provided at the lower middle end of the lower cavity, and a plurality of wipers are installed in the lower cavity.
