Description

Drainage type breathing machine pipeline

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a drainage type breathing machine pipeline.

Background

In the mechanical ventilation process, continuous humidification is needed to avoid the problems of airway dryness, airway mucous membrane damage, sputum scab dryness and the like, which are not easy to eliminate. However, the humidified gas and the gas exhaled by the patient contain more water vapour, which results in condensation of the gas as it passes through the ventilator circuit to form condensed water. The condensed water should be timely removed to avoid blocking or blockage of the ventilator circuit and thus influence the treatment effect of mechanical ventilation, and meanwhile, attention should be paid to avoid pulmonary infection caused by reflux of the condensed water. The water collecting cup on the breathing machine pipeline is designed for collecting condensed water and promoting the condensed water to be discharged out of the breathing machine pipeline. However, in the clinical practice process, due to the influence of factors such as the treatment requirement of a patient, the placement of the body position, the relative position of a breathing machine and a sickbed, and the like, the water collecting cups of the breathing pipe and the air suction pipe are often difficult to be at the lowest position at the same time, so that condensed water cannot flow into the water collecting cup. At this time, the condensed water needs to be manually introduced into the water collecting cup, so that the narrow or blockage of the breathing machine loop is avoided. Meanwhile, the interfaces of the breathing machine pipeline and the water collecting cup are more, and the breathing machine pipeline and the water collecting cup are not provided with a fixing device. In clinic, the patient can be moved, the breathing machine can be moved, the patient position can be adjusted, the patient can be choked, and the like, and the connection part of the breathing machine loop and the water collecting cup can be disconnected, so that the mechanical ventilation is invalid, and the patient safety is threatened.

Chinese patent No. CN106110458B discloses a sliding water collecting cup type breathing machine pipeline, which comprises a Y-shaped joint, an air suction pipe, an air breathing pipe and sliding water collecting cups, wherein the side walls of the air breathing pipe and the air breathing pipe are respectively provided with a sliding part, the sliding parts are axially provided with slits, two sides of the slits are respectively provided with concave-convex buckles in opposite directions, two sides of the top of the sliding water collecting cup are respectively provided with concave-convex buckles in opposite directions, two ends of the top of the sliding water collecting cup are respectively provided with a pull head, and the two sliding water collecting cups are respectively communicated with the air breathing pipe and the air breathing pipe. The position of the water collecting cup can be adjusted to be always positioned at the lowest position of the pipeline of the breathing machine, so that the collection of condensed water is ensured; but also can avoid the breakage and falling of the pipeline; and can avoid the inhalation of medicines to pollute the breathing machine. However, there is a problem in that the tightness between the sliding water collection cup and the inhalation or exhalation tube is not easy to handle, and the ventilator circuit may leak, thereby affecting the overall effect of mechanical ventilation.
