Novel trachea cannula

Abstract

The invention discloses a novel trachea cannula. The novel trachea cannula comprises an air tube, wherein a positioning module is arranged at one end of the air tube; and an import module is arrangedon an outer wall of the air tube and connected with the positioning module. According to the novel trachea cannula, the positioning module emits light through the import module, so that on one hand, the insertion depth of the trachea cannula can be intuitively reflected, and the problem that insufficient ventilation in a patient is caused by one-lung ventilation due to the fact that the trachea cannula is inserted too deep and enters unilateral bronchus by mistake or the problem that the trachea cannula is inserted too shallow to escape is avoided; and on the other hand, whether the trachea cannula correctly enters an airway or not can be judged in an auxiliary manner, the accuracy and efficiency of the trachea cannula of a medical worker are improved, the novel trachea cannula is convenient and fast to operate, safe, reliable, relatively low in cost, and high in practicability and generalization performance.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a novel tracheal intubation tube. Background technique [0002] Endotracheal intubation has become an important measure in cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. Endotracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and fastest methods in respiratory management. It is a basic skill that medical personnel must master proficiently. to a vital role. As far as the existing respiratory diseases are concerned, the rapidity and accuracy of endotracheal intubation are very important; among them, the standard of rapidity is whether it can quickly judge whether the catheter enters the airway, and the standard of accuracy is the ability to Whether to clearly locate the depth of the catheter into the trachea; [0003] a. Existing methods for ju...

Problems solved by technology

[0006] a. Problems with successful tracheal insertion: ① For patients with difficulty in glottis exposure (such as small mouth opening, small mandible, ankylosed temporomandibular joint, obesity, short neck, snoring, oral and laryngopharyngeal surgery or history of radiotherapy and chemotherapy) patients), there is no evidence of the endotracheal tube entering the glottis under photopic vision; ②Patients who are obese or complicated with lung diseases, the breath sounds of both lungs may be unclear on auscultation; Road pressure may rise rapidly accompanied by changes in CO2 waveform;

[0007] b. There are still problems in judging the depth of intubation: ① If the patient has growth and development diseases, such as dwarfism, rickets, gigantism, etc., the empirical formula may make a wrong judgment, and it is not suitable for newborns with very low kilogram body weight and premature births. For children, there is no relevant empirical formula; ②Auscultation often has the possibility of subjective judgment error; ③The airway pressure may vary from person to person, for example, the main airway pressure in patients with obesity and pulmonary fibrosis often exceeds the normal range, and may be due to Due to factors such as changes in the patient's body position or increased abdominal pressure, catheter displacement occurs, resulting in too deep or too shallow intubation depth; ④ Bronchoscopy checks the depth of a patient's intubation and requires routine disinfection before reuse. The risk of cross-infection is caused; and the bronchoscope is expensive and inconvenient to carry. If a large number of surgical patients are to be inspected for the depth of intubation in a short period of time, or carried to the ward for emergency intubation from a long distance, it is necessary to keep multiple branches. Fiber optics will inevitably significantly increase health costs and economic burdens
