Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a ventilator extension tube with a drainage device. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing the spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and they occupy a very important position in the field of modern medicine. In the process of ventilator-assisted patient breathing, the ventilator extension tube is an accessory of the ventilator, which is mainly composed of a threaded tube and an extension tube, a patient interface and a machine interface. The respiratory extension tube is a connecting device between the human respiratory tracheal tube and the ventilator to ensure that the ventilator pipeline will not pull the tracheal tube.

[0003] However, after adding the extension tube, the temperature of the airflow in the tube will be higher. When this airflow passes through the extension tube, if the indoor temperature is low, a certain temperature difference will be formed inside and outside the tube, and water droplets will be generated in the extension tube, which is condensed water. Clinically, it is found that after raising the patient's bedside and fixing the ventilator pipeline, there is often a low position between the patient's artificial airway (endotracheal tube or tracheostomy tube) and the ventilator pipeline, that is, the position of the ventilator extension tube, causing condensed water to accumulate here. If the condensed water is not handled, it is easy for the condensed water to flow back into the patient's airway, and it is easy to form water accumulation in the ventilator extension tube, causing the ventilator to alarm, and a sawtooth waveform will appear on the pressure-time curve.

[0004] Therefore, the condensed water must be collected and processed. In the prior art, the authorization announcement number CN220237510U discloses a retractable anti-water accumulation breathing tube for critical care ventilators, which specifically discloses that it includes two bellows and a three-way joint. The two bellows are respectively sealed and rotatably connected to the interfaces on both sides of the three-way joint. The lower interface of the three-way joint is threadedly connected with a water accumulation bottle. The utility model can keep the water accumulation cup in the lowest position at all times, which is convenient for medical staff to grasp the situation and operate. Although the utility model can keep the water accumulation cup in the lowest position at all times, and the water accumulation bottle is connected by a thread, medical staff can remove it to handle the accumulated water or clean and disinfect it. However, the water accumulation bottle is threadedly connected to the three-way pipe, which makes it difficult to remove or install, increasing the labor intensity of medical staff.
