Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a retrograde intubation suit for children with difficult airways. Background Art

[0002] Difficult airway refers to a clinical situation in which anesthesiologists with more than five years of clinical anesthesia experience encounter difficulty with mask ventilation (upper airway obstruction), difficulty with endotracheal intubation, or both. The management of difficult airway is closely related to anesthesia safety and quality. More than 50% of serious anesthesia-related complications are caused by improper airway management.

[0003] With the increasing incidence of childhood cancer, upper airway tumors, such as those at the base of the tongue and epiglottis, are common clinical findings. Another common symptom is head and facial trauma, resulting in soft tissue damage in the oral cavity or fractures of the upper and lower jaws, leading to a difficult airway. Conventional intubation or bronchoscopy cannot establish an artificial airway, making anesthesia difficult. Anesthesia and mechanical ventilation must be administered only after a secure airway is established. Therefore, this process requires the use of retrograde intubation tools to establish an artificial airway and ensure safe anesthesia. For these critically ill children, awake intubation is typically performed, which is painful and unreliable. Children often have poor cooperation, making slow induction difficult. Existing retrograde intubation guides lack protective and ventilated needles. Conventional needles are prone to damage and carry the risk of perforating the posterior tracheal wall. Furthermore, there are no similar pigtail soft guidewire guidance systems, and these kits are rarely available on the market. Utility Model Content
