Tracheal catheter integrating cardiac defibrillation and multifunctional monitoring

Abstract

The invention discloses a tracheal catheter integrating cardiac defibrillation and multifunctional monitoring. Through design of an inner electrode and an outer electrode, and after intubation is completed, by means of a loop formed by the inner electrode and the outer electrode, the purpose of defibrillation of a patient is achieved. Compared with transthoracic defibrillation in the prior art, the tracheal catheter disclosed by the invention has the advantages of being better in defibrillation effects, more convenient, free from bacteria and lower in power. Secondly, pressure and acoustics dual detection is adopted, so that a doctor can conveniently know the pressure states of an inflated cuff and the body of the patient after inflation, the problem of ischemia necrosis of tracheal mucosadue to gastric reflux caused by over-low pressure or over-high pressure is effectively solved, and in addition, acoustic noise of heart activity in the body of the patient can also be detected. Medical staff can conveniently have a good grasp and judgment of the heart state of the patient in the follow-up stage. Through cooperation with a combined structure, the requirement for convenient switching between the two states of conventional intubation or defibrillation multifunctional monitoring is met, in conclusion, the clinical practicability is expanded, and extremely high application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endotracheal tube that takes into account both cardiac defibrillation and multifunctional monitoring. Background technique [0002] Endotracheal intubation refers to inserting a special endotracheal tube into the patient's trachea through the mouth or nose. It is a technique commonly used in clinical anesthesia and rescue of patients to control the airway and maintain ventilation. During general anesthesia, it is mainly used for those who are difficult to keep the airway open, such as: intracranial surgery, thoracotomy, general anesthesia surgery requiring special positions such as prone position or sitting position, jaw, extremely obese patients, and general anesthetics that have obvious inhibition on breathing Or those who use muscle relaxants and those who have major operations under general anesthesia on the face, neck, and five sense organs, all of the above situa...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing clinical doctors and nurses can only rely on experience to judge whether the pressure of the cuff is appropriate, which is not objective and accurate enough. If the pressure of the inflatable cuff is insufficient, gastric reflux will enter the lungs and cause pneumonia; and if the pressure of the inflatable cuff is too high High, it will lead to ischemic necrosis of tracheal mucosa, postoperative scar stenosis, and then increase the incidence of perioperative pneumonia, and make patients more likely to form postoperative scar stenosis

[0005] 2. In the existing clinical process of cardiopulmonary resuscitation for patients, defibrillators are generally used to perform defibrillation operations outside the patient's body. This traditional method is limited by the electrical conductivity of the outside body, so the stimulation effect is poor, which greatly affects defibrillation. first aid

[0006] 3. During the treatment of critically ill patients such as respiratory failure, medical staff will use ECG monitors to achieve effective monitoring of the patient's heart status, allowing medical staff to understand and grasp the patient's status in real time, but traditional ECG monitoring The detection electrodes of the equipment are all fixed outside the patient’s body, so not only the monitoring effect is poor, but it is also vulnerable to external interference or collision and fall off. In addition, medical staff are required to fix multiple detection electrodes on the patient’s body, which increases the burden of operation and ultimately brings great harm to the clinic. Use brings a lot of inconvenience
