Novel tracheal catheter

Abstract

The invention discloses a novel tracheal catheter. The novel tracheal catheter comprises a catheter body composed of a hard inner cannula and a hard outer cannula, the catheter body is provided with an expansion airbag, the two ends of the outer cannula are fixedly connected with the outer wall of the inner cannula to form a sealing cavity in the middle, the rear end of the outer cannula is provided with an inflating catheter, and scale identifications are marked on the inflation pipe; the expansion airbag is fixedly connected to the front end of the outer cannula in a sealed mode, the front end of the expansion airbag sinks inward to form a bowl-shaped thickened support surface, the front end of the inner cannula is fixedly connected with the bowl-shaped thickened support surface, and the bowl-shaped thickened support surface is provided with a opened hole corresponding to the cannula hole of the inner cannula; the inflating catheter penetrates into the rear end of the outer cannula and is communicated with the expansion airbag; the front end of the outer cannula is provided with sieve meshes, the rear end of the outer cannula is provided with a liquid suction pipe, and the outer cannula is sleeved with a hard mouthpiece; the rear edge of the mouthpiece is turned over outward to form a lip blocking plate, the outer periphery of the mouthpiece is covered with a soft rubber layer, and the outer wall of the outer cannula of the front part of the mouthpiece is provided with a clamping block; the rear end of the inner cannula is provided with a connecting head. The novel tracheal catheter has the advantages of being simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a medical device, in particular to a novel trachea tube. Background technique [0002] Endotracheal intubation refers to inserting a special endotracheal tube into the patient's trachea through the oral or nasal cavity; it is a technique for endotracheal anesthesia and patient rescue, and it is also the most reliable means of keeping the upper airway open. Tracheal intubation is required when the following situations occur: 1. Patients whose airway is difficult to ensure unobstructed during general anesthesia, such as intracranial surgery, thoracotomy, general anesthesia surgery requiring special positions such as prone position or sitting position; Patients with major operations under general anesthesia such as internal tumors compressing the trachea, jaw, face, neck, and facial features, and extremely obese patients; patients with obvious inhibition of breathing by general anesthesia or who are treated with muscle relaxants s...

AI Technical Summary

Problems solved by technology

[0004] The existing dilation balloon cannot completely cover the front end of the endotracheal tube, and the liquid (such as sputum) in the human trachea will accumulate between the endotracheal tube at the front of the dilation balloon and the human trachea wall for a long time; It can only absorb the liquid inside the endotracheal tube, so a large amount of liquid will accumulate between the endotracheal tube at the back of the dilated balloon and the human body's trachea wall; the long-term accumulation of liquid will affect the patient's breathing, cause choking, and easily lead to bacterial infection; The endotracheal tube is also unable to flush or locally apply drugs to the human tracheal wall behind the dilated balloon

In addition, since the hollow hard tube and the endotracheal tube are not integral structures, and are placed after the endotracheal tube is intubated, the patient’s mouth needs to be opened again when placing it, which is troublesome to operate; at the same time, there is no fall-off structure under the hollow hard tube, It is very easy to slide into the patient's mouth and cause damage to it, and there is no elastic layer on the hollow hard tube, which may cause damage to the patient's teeth after the patient's teeth are clenched
