Description

Movable water collecting cup type breathing machine pipeline

Technical Field

The invention relates to the technical field of breathing machine pipelines, in particular to a movable water collecting cup type breathing machine pipeline.

Background

Mechanical ventilation is the most timely and effective treatment means for respiratory failure caused by various reasons, and is generally applied to respiratory medicine, thoracic surgery, emergency department, intensive care unit, operating room, geriatric unit, infectious disease unit and the like. In the process of mechanical ventilation, continuous humidification is needed to avoid airway dryness, airway mucosal injury, sputum scab dryness and the like, which are not easy to remove. However, the humidified and exhaled air contains a large amount of water vapor, and the inhaled and exhaled air is condensed to form condensed water when passing through the ventilator circuit. The ' mechanical ventilation clinical application guide ' issued by the medical division of severe cases of the Chinese medical society recommends that condensed water in a respirator pipeline should be removed in time ' and the recommended level is grade B.

The water collecting cup is designed for collecting the condensed water and promoting the condensed water to be discharged out of the breathing machine pipeline. However, in the clinical practice process, we have found that it is often difficult to locate the water collecting cups of the exhalation tube and the inhalation tube at the lowest position at the same time due to the needs of patient treatment, the placement of the body position, and the relative position of the ventilator and the hospital bed. Thereby lead to the unable water cup that catchments that flows into of comdenstion water to the gathering is in the breathing machine pipeline, makes breathing machine pipeline stenosis even block up, thereby influences mechanical ventilation effect, causes palirrhea mistake and inhales even, causes stifling or lung infection etc. thereby threatens patient life safety. The accumulation and backflow of the condensed water can affect the mechanical ventilation effect and increase the occurrence of ventilator-related pneumonia, so that a water collecting cup for collecting the condensed water is required to be placed at a low position so as to facilitate the collection of the condensed water and timely clear the condensed water in a ventilator pipeline.

In the clinical practical process, through a plurality of attempts, the water collecting cups of 2 loops are difficult to be simultaneously placed at the lowest position; the water collecting cup at the lowest position of the breathing machine loop can smoothly collect the condensed water, and the water collecting cup which is not at the lowest position can not collect the condensed water, so that the condensed water is gathered in the breathing machine loop, and at the moment, the condensed water needs to be artificially introduced into the water collecting cup, so that the breathing machine loop is prevented from being narrow or blocked. Meanwhile, the breathing machine has more interfaces with the water collecting cup and does not have a fixing device. In clinical practice, patients are moved, the breathing machine is moved, the body position of the patients is adjusted, the patients are choked, and the like, which can cause the disconnection of the connection part of the breathing machine loop and the water collecting cup, thus leading to ineffective mechanical ventilation and threatening the safety of the patients.
