Adjustable trachea model

Abstract

The invention relates to an adjustable tracheal model. The model comprises a main airway, a left main bronchus and a right main bronchus; the left main bronchus and the right main bronchus are connected with the same end of the main airway separately and provided with a left marker and a right marker respectively, the distance between the left marker and the right marker relative to the main airway is adjustable, and the left marker and the right marker are used for marking the positions of a left lung upper lobe bronchus opening and a right lung upper lobe bronchus opening respectively. The tracheal model is simple and compact in structure and convenient to use, the positions of the left lung upper lobe bronchus and the right lung upper lobe bronchus can be accurately adjusted according to a CT three-dimensional reconstructed image, a double-lumen bronchus catheter of a suitable type is selected for a patient by utilizing the adjusted model, the purpose of selecting the type of the double-lumen bronchus catheter can be effectively achieved, intubation and alignment on the model can be simulated, the success rate of aligning the double-lumen bronchus catheter can be increased, tracheal injuries can be avoided, the waste of the double-lumen bronchus catheter can also be avoided, and the anesthesia cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable trachea model. Background technique [0002] The double-lumen bronchial catheter is one of the endotracheal catheters, which is used for bronchial intubation; its feature is that it can separate the left and right lungs to achieve double lung isolation, and it is a thoracic operation (lung, esophagus, etc.) to achieve single-lung ventilation. The main tool to provide better surgical conditions, it can be used for ventilation through both sides of the lumen, or only the uninjured side of the lumen, and can suck the secretions separately at any time. It is a necessary consumable for lung abscess and tuberculosis surgery. [0003] At present, the commonly used double-lumen bronchial tubes are divided into left double-lumen tube and right double-lumen tube. Among them, the left double-lumen tube is the Carlen tube, which is a tube that enters the left main bronc...

AI Technical Summary

Problems solved by technology

[0004] The trachea structure of the human body mainly includes the main airway, the left main bronchus and the right main bronchus connected with the main airway. One end of the carina is respectively connected with the left upper lobe bronchus and the left lower lobe bronchus, and the end of the right main bronchus away from the carina is connected with the right upper lobe bronchus, right middle lobe bronchus and right lower lobe bronchus respectively ; For each person, the distance between the left upper lobe bronchus and the opening of the left lower lobe bronchus and the carina, and the distance between the right upper lobe bronchus and the opening of the right middle lower lobe bronchus and the carina are usually different, and thus have different clinical implications. Selection of double lumen bronchial catheter size in surgical anesthesia poses difficulties

However, in the prior art, the anesthetist usually selects the suitable double-lumen bronchial catheter model for the patient based on the patient’s height, weight and other parameters, combined with clinical experience. It often causes difficulty in aligning the catheter and requires multiple alignments, which can easily cause tracheal damage

If multiple alignment failures are caused by improper catheter type, the endotracheal intubation and alignment can only be performed again with a new catheter of another type. , but also increased the cost of anesthesia and the financial burden on patients
