Breathing guide trachea cannula guide wire and application thereof to trachea cannula

Abstract

The invention discloses a breathing guide trachea cannula guide wire and application thereof to a trachea cannula, and belongs to the technical field of medicinal instruments. The breathing guide trachea cannula guide wire comprises a shell, and a first channel used for injecting narcotic is formed in the shell in the axial direction; the first channel comprises a dosing end extending out of the shell; the dosing end is sleeved with a spray head which is in slide connection with the first channel; the periphery of the spray head is coated with a soft capsule used for storing the narcotic; thesoft capsule is communicated with the first channel through a first through hole formed in the spray head; the spray head is further provided with a second through hole for spraying the narcotic whena patient is in an inspiration state. By adopting the breathing guide trachea cannula guide wire, the problems that the existing trachea cannula guide wire cannot realize dosing and the process of introducing the guide wire into the airway in cooperation with the autonomous respiration of the patient, cannot control the dosage and has poor dosing effect are solved. The breathing guide trachea cannula guide wire has the advantages of capability of dosing and introducing the guide wire into the airway in cooperation with the autonomous respiration of the patient, and good dosing effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a breathing-guided tracheal intubation wire and its application in tracheal intubation. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. It is an important technique to ensure unobstructed airway, effective ventilation and oxygen supply and avoid aspiration in emergency and general anesthesia. The solutions for difficult airway tracheal intubation mainly include ordinary laryngoscope, video laryngoscope, fiberoptic bronchoscope, rigid fiberoptic bronchoscope, cricothyroid puncture guide, bougie, etc. However, the above-mentioned solutions all have relatively high requirements for direct vision of the glottis. When the airway is extremely difficult and the glottis is not exposed well, tracheal intubation is very difficult, which brings great troubles to c...
