Three-channel tracheal catheter device for neonatal RDS breathing rescue

Abstract

The invention relates to the technical field of medical instruments, and discloses a three-channel tracheal catheter device for neonatal RDS breathing rescue. The three-channel tracheal catheter device for neonatal RDS breathing rescue comprises an inner tube, wherein a cuff is arranged at the outlet end of the inner tube, a guide surface in sliding fit with the epiglottis is formed on the cuff, an outer tube is slidably connected to the outside of the inner tube, the inner tube penetrates through the outer tube, the inner tube comprises a deformation part, the deformation part can generate elastic deformation and bend when subjected to external force, a bending assembly is arranged between the inner tube and the outer tube, the bending assembly can generate uneven pulling force on the inner tube to bend the inner tube, the orientation of the outlet end of the inner tube can be adjusted by controlling the bending assembly, therefore, before the outlet end of the inner tube reaches the annular cartilage plate, the inner tube is controlled to bend, the outlet end of the inner tube can face the direction where the trachea is located, and then the inner tube is prevented from falling into the esophagus.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a three-channel endotracheal catheter device for neonatal RDS respiratory rescue. Background technique [0002] Neonatal respiratory distress syndrome (RDS), also known as hyaline membrane disease, is a serious lung disease caused by pulmonary surfactant (PS) deficiency, with progressive aggravation of respiratory distress as the main clinical manifestation, and it is more common in premature infants. Newborns with RDS who are in stable condition under non-invasive respiratory support usually adopt tracheal intubation-inject PS liquid medicine-extubation and use positive pressure ventilation technology to supplement PS liquid medicine. The resuscitation bag is pressurized to supply oxygen, and the PS drug solution is drawn into a 5ml syringe in advance and connected to a No. 5 half scalp needle. The scalp needle is inserted into the endotracheal tube from the side of the ...

AI Technical Summary

Problems solved by technology

[0003] During intubation, the patient lies down with his head back and opens his mouth. The operator extends the front end of the endotracheal tube from the mouth. The endotracheal tube enters the larynx from the epiglottis and enters the trachea after reaching the cricoid cartilage plate. The cricoid cartilage plate is the larynx The boundary mark with the trachea, pharynx and esophagus. When the patient is lying down, the esophagus is located below the trachea. The existing tracheal tube is straight, and the tracheal tube can easily enter the esophagus during the process of extending down the pharynx. Intubation The success rate of the endotracheal tube is low, and the insertion path of the endotracheal tube is curved, which makes the endotracheal tube easily stuck in the larynx during intubation, which brings great pain to the patient
