Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a double-balloon device for fetal diaphragmatic hernia airway embolization surgery. Background Art

[0002] At present, the treatment plan for fetal diaphragmatic hernia airway embolism at home and abroad is to use a "sacculus dilatation catheter". The specific principles of its use include: when congenital diaphragmatic hernia is diagnosed within 24-28 weeks of the fetus, when the examination data indicates severe diaphragmatic hernia (indicating a poor prognosis), a sacculus dilatation balloon catheter is placed in the fetal airway through the mother's uterus using a fetoscope at 28 weeks of the fetus, and remains therein. The purpose is to promote the alveolar development of the fetal lungs. The sacculus dilatation balloon is generally removed through an otolaryngoscope at around 37-40 weeks of the fetus when the fetus is born and the umbilical cord has not been cut. The following problems exist in the use of traditional luminal dilatation balloons: 1. The luminal dilatation balloon is generally fixed on the main airway (relatively thick). During use, it was found that after the balloon was punctured, the luminal dilatation balloon moved to a farther and thinner airway, making it more difficult to remove the balloon; 2. The luminal dilatation balloon is usually removed by grasping and embedding, which often fails to clamp the luminal dilatation balloon and cannot be removed; 3. There have been reports of medical records of balloons disappearing and being unable to be found both at home and abroad, resulting in poor safety in the use of traditional luminal dilatation balloons. Summary of the invention

[0003] Based on this, it is necessary to provide a double-balloon device for fetal diaphragmatic hernia airway embolization surgery that is easy to use, easy to remove and highly safe to use.
