Surgical double-sacculus apparatus for fetal diaphragmatic hernia airway embolism

Abstract

The invention discloses surgical double-sacculus apparatus for a fetal diaphragmatic hernia airway embolism. The surgical double-sacculus apparatus for the fetal diaphragmatic hernia airway embolism comprises a first sacculus, a second sacculus and a connecting pipe body; the first sacculus is provided with a first sacculus cavity; the second sacculus is provided with a sacculus cavity; the firstsacculus and the second sacculus are connected by the connecting pipe body; the first sacculus cavity and the second sacculus cavity communicate through the connecting pipe body; and the first sacculus and the second sacculus are both elastic. The surgical double-sacculus apparatus for the fetal diaphragmatic hernia airway embolism can be applied to a therapeutic schedule of the fetal diaphragmatic hernia airway embolism. When the apparatus is used, the second sacculus is put in and stays in the airway of a fetus to promote the development of pulmonary alveoli of the lungs of the fetus; the first sacculus is placed inside or outside the oral cavity of the fetus, and the first sacculus can be taken out only by being pierced; and gas or liquid in the first sacculus, the second sacculus and the connecting pipe body is released, and the second sacculus contracts, and thus, the second sacculus located in the airway of the fetus can be rapidly taken out conveniently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a double-balloon device for fetal diaphragmatic hernia airway embolization. Background technique [0002] At present, the treatment plan for fetal diaphragmatic hernia airway embolism at home and abroad is to use "sacculus dilatation catheter (Sacculus dilatation catheter)". When the data represent a severe diaphragmatic hernia (representing a poor prognosis), a lumen dilatation balloon catheter was placed and retained in the fetal airway using a fetoscope through the mother's uterus at 28 weeks in order to promote alveolar development in the fetal lungs , the lumen expansion balloon is usually taken out through an otolaryngoscope when the fetus is born around 37-40 weeks and the umbilical cord is not cut. The following problems exist in the use of the traditional lumen dilation balloon: 1. The lumen dilation balloon is generally fixed on the main airway (relatively thick), and it...

AI Technical Summary

Problems solved by technology

The following problems exist in the use of the traditional lumen dilation balloon: 1. The lumen dilation balloon is generally fixed on the main airway (relatively thick), and it is found that the lumen dilation balloon runs to a further place after the balloon is punctured during use. The farther and thinner airway makes it more difficult to take out the balloon; 2. The method of taking out an...
