Abstract
Description
Technical Field
[0001] The utility model relates to the field of intubation, in particular to a uniform-speed drug delivery component and a double-lumen endotracheal intubation. Background Art
[0002] Neonatal respiratory distress syndrome is common in premature infants. The main pathogenesis is alveolar collapse due to lack of PS (pulmonary surfactant). The clinical manifestations of the children are progressive dyspnea within 6 to 12 hours after birth. In severe cases, it progresses to respiratory failure, hypoxemia and even death. PS can reduce alveolar surface tension, prevent alveolar collapse, and ensure the normal gas exchange in the alveoli. It is mainly used to prevent and treat neonatal respiratory distress syndrome. In recent years, PS has been widely used in severe neonatal pneumonia, meconium aspiration syndrome, pulmonary hemorrhage and bronchopulmonary dysplasia.
[0003] At present, the PS injection method widely used in clinical practice often adopts the tracheal injection method, which involves inserting a tracheal tube into the trachea, drawing a certain amount of PS solution with a syringe, and penetrating the outer wall of the inlet end of the tracheal tube with the needle of the syringe. The syringe is manually pushed to allow the PS solution to drip slowly into the lungs. However, the administration time is long and it is difficult to control the uniform speed of the PS solution dripping. Too fast an administration speed will cause the PS solution to accumulate in the lungs, affecting the efficacy. The work procedure is cumbersome and difficult to operate, which brings many inconveniences to medical staff. Utility Model Content
