Trachea cannula capable of removing sputum accumulation and relieving inflammatory reaction

Abstract

The invention relates to a trachea cannula capable of removing sputum accumulation and relieving inflammatory reaction. The trachea cannula is provided with a cannula body, a breathing machine connector, an air vent, an airbag, an inflating passage and an inflating tube, wherein hydrophobic and oleophobic layers are arranged on the inner wall and the outer wall of the cannula body as well as on the outer wall of the airbag; a plurality of convex rings are arranged on the airbag, and the convex ring at the nearest end protrudes towards a near end, so that an accommodating groove is formed between a balloon and the cannula body; the edge of the air vent is coiled towards the near end, so that a receiving groove is formed; a sputum suction passage is formed in the inner wall of the cannula body; the sputum suction passage is provided with a first sputum suction hole and a second sputum suction hole; an opening at the far end of the sputum suction passage is a third sputum suction hole; the first sputum suction hole is opened outwards; the second sputum suction hole communicates with the accommodating groove; the third sputum suction hole communicates with the receiving groove; and a sputum suction tube is connected to the near end of the sputum suction passage. With the application of the trachea cannula provided by the invention, sputum can be thoroughly removed, planting and growth of pathogenic bacteria can be relieved, and an infection probability and an occurrence rate of the inflammatory reaction can be reduced; and the trachea cannula is fixed more firmly and cannot cause displacement and air leakage easily.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tracheal intubation tube capable of removing sputum accumulation and reducing inflammation. Background technique [0002] Endotracheal intubation technology is widely used in emergency departments, various ICUs, anesthesiology departments, various wards and various emergency scenes outside the hospital. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration. [0003] Under normal circumstances, due to the natural reaction of the oral cavity to the insertion of foreign objects, a large amount of saliva, sputum and other secretions will be produced. Various liquids are mixed together and flow to the balloon under the action of gravity, forming sputum here. It is also easy to adhere to the inner and outer walls of the endotracheal tube, which not only causes the patient's sensory disco...

AI Technical Summary

Problems solved by technology

However, this method of operation has the risk of causing the secretions on the inner wall of the endotracheal tube to drop, and the operation is relatively cumbersome, and sputum suction is still required after washing and cleaning

[0005] At present, there is no endotracheal intubation that can simply and effectively remove sputum to avoid poor ventilation, viral infection and patient discomfort, and can effectively reduce airway inflammation
