Single-lumen double-bag bronchial intubation

Abstract

The invention provides a single-cavity double-air bag bronchial cannula and belongs to the technical field of medical instrument trachea cannulas. The single-cavity double-bag bronchial cannula comprises a tracheal catheter, a catheter connector, a tracheal cuff, a bronchial catheter, a bronchial cuff, and a tracheal cuff inflation valve. One side of the tracheal catheter between the tracheal cuff and the bronchial cuff is provided with a tracheal catheter side hole; the bronchial catheter in the bronchial cuff is provided with a bronchial catheter side hole; the bronchial catheter side hole is provided with an elastic film; when the bronchial cuff is inflated, the elastic film can sink inward to be pressed against the inner wall of the bronchial catheter to seal the bronchial catheter. The single-cavity double-bag bronchial cannula can achieve the lung separation effect of single-cavity three-bag design by using the single-cavity double-bag design and can be made into different specifications with the internal diameter being 3.0-10.0mm, so that the injury caused to patients by the cannula is effectively reduced and the production difficulty is greatly reduced. The single-cavity double-bag bronchial cannula can be used for both single-side ventilation and double-side ventilation and most importantly, can meet the requirement for one-lung ventilation in adult and infant surgery, so that the universality is greatly improved.

Description

technical field [0001] The invention belongs to medical appliances, in particular to a bronchial insert, which is mainly used for one-lung ventilation required for lung isolation in thoracic surgery for adults and children. Background technique [0002] Due to the rapid development of minimally invasive techniques, more and more thoracic surgeries require unilateral lung ventilation. At present, single-lung ventilation is usually isolated with a double-lumen bronchial catheter. The diameter of the double-lumen tracheal intubation tube is relatively large, so it is difficult to operate. It is easy to cause respiratory complications. In addition, for infants and young children, because the trachea for breathing is relatively thin, thicker intubation tubes cannot be inserted. There are also single-lumen bronchial tubes in current products, but this single-lumen bronchial tube requires both To achieve two-way ventilation and one-way ventilation, an air bag must be added in the b...

Problems solved by technology

[0002] Due to the rapid development of minimally invasive techniques, more and more thoracic surgeries require unilateral lung ventilation. At present, single-lung ventilation is usually isolated with a double-lumen bronchial catheter. The diameter of the double-lumen tracheal intubation tube is relatively large, so it is difficult to operate. It is easy to cause respiratory complications. In addition, for infants and young children, because the trachea for breathing is relatively thin, thicker intubation tubes cannot be inserted. There are also single-lumen bronchial tubes in current products, but this single-lumen bronchial tube requires both To achieve two-way ventilation and one-way ventilation, an air bag must be added in the bronchi to block the bronchi to achieve one-way ventilation. At present, the inner diameter of this kind of intubation tube is greater than 6.5mm, and the air bag cannot be installed in the tube smaller than 6.5mm Therefore, it is impossible to produce, which eventually leads to no available tubes for infants and young children; it cannot meet the clinical needs, so it is necessary to develop a simple and easy operation, easy to manufacture, less clinical complications, and can meet the needs of patients of different ages for one-lung ventilation. endotracheal tube
