Embodiment 1

[0024] A non-invasive tracheal intubation guiding device sequentially includes a floating ball, an inflatable anchoring cuff and an inflation catheter, the inflation catheter is connected to an inflation device, and the inflation device inflates the anchor cuff through the inflation catheter, and the anchor cuff A ring-shaped structure is adopted, and an air passage is sheathed on the outside of the floating ball, the anchoring cuff and the inflation catheter. The air passage adopts a C-shaped structure. The floating ball and the anchoring cuff are made of medical rubber.

[0025] Parameters of each component:

[0026] 1) The floating ball is a hemisphere filled with light gas, with a diameter of 5mm. By calculating the model and using Fluent6.2.13 software for numerical simulation calculations, in the trachea model with a diameter of 15mm and a minimum airflow velocity of 3L / s, it can Generate a pulling force greater than 0.00775N (0.775gf), which is enough to pull the thre...

Abstract

The invention relates to a noninvasive trachea cannula guiding device which comprises a trachea cannula. The noninvasive trachea cannula guiding device is characterized in that the device comprises a floating ball, an inflatable anchoring cuff and an inflating guide pipe in sequence, wherein the inflating guide pipe is connected with inflation equipment; the inflation equipment inflates air into the anchoring cuff through the inflating guide pipe; the anchoring cuff adopts a circular ring structure; and an air passage is sleeved outside the floating ball, the inflatable anchoring cuff and the inflating guide pipe. The noninvasive trachea cannula guiding device has the characteristics that through the natural air suction of the patients or the veil pressurizing ventilation, the floating ball can enter into the airway of the patients under the protection of the air passage; after reaching certain depth, the anchoring cuff is deformed into a ring-shaped airbag through the inflation by the inflating guide pipe; the anchoring function is realized; and the trachea cannula is guided to enter the air pipe after the positioning.

Description

technical field [0001] The invention belongs to the technical field of medical consumables, and in particular relates to a guiding device for inserting a medical endotracheal tube. Background technique [0002] Endotracheal intubation is an essential technique for endotracheal anesthesia, cardio-cerebral pulmonary resuscitation and respiratory therapy. Commonly used methods for tracheal intubation in clinical daily work are: ① Laryngoscopic endotracheal intubation: This is the most commonly used method. Anesthesia laryngoscopy completes intubation. This method requires the patient to have good mobility of the atlanto-occipital joint and cervical spine, and the three axes of the mouth, pharynx, and larynx must be able to overlap during tracheal intubation. At the same time, it is also affected by the degree of mouth opening of the patient and the classification of Mallampati's airway. Those with difficulty in opening the mouth and those with high classification scores are di...
