Description

Visual double-cavity trachea cannula

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a visible double-cavity trachea cannula.

Background

Clinically, the method ensures that the respiratory tract is unobstructed, maintains normal gas exchange, is a task which must be solved firstly when critical patients such as anesthetized patients, severe trauma patients, respiratory arrest patients and the like are rescued, maintains the normal functions of all organs of the organism, and further completes basic guarantee of circulation, resuscitation of the central nervous system and renal function rescue when necessary. The trachea cannula technology is often used in the rescue process of general anesthesia operation or cardiopulmonary resuscitation and critical patients accompanied with respiratory dysfunction, the trachea cannula is a technology of placing a special catheter into the trachea through the glottis, and the emergency trachea cannula technology becomes an important measure in the rescue process of cardiopulmonary resuscitation and critical patients accompanied with respiratory dysfunction.

The double-cavity bronchial catheter is widely used for separating the two lungs in the chest surgery lung operation, so that the two lungs are isolated while the lungs of a patient are ventilated, and the phenomenon that secretions, interstitial fluid or blood in the lung which is subjected to the operation enter the other lung to infect the lung which is not subjected to the operation is avoided, so that the protection effect is achieved.

At present, visible double-cavity trachea cannulas in the market adopt an inflatable balloon for fixing, preventing dropping and sealing. The balloon is inflated to seal the gap between the periphery of the catheter and the tracheal wall, so that air leakage during positive pressure ventilation is prevented, and backflow of upper respiratory secretions or gastric contents is avoided. However, the air bag is easy to extrude the inner wall of the air passage when over-inflated, so that the blood flow of the tracheal mucosa is blocked, and a series of complications are generated to cause injury to people. On the other hand, the balloon may cause air leakage in the patient's body for a long time, may impair the therapeutic effect of mechanical ventilation, and may affect the fixation of the endotracheal tube, and such air leakage may even cause serious medical accidents.

The utility model provides a visual double-cavity tracheal cannula to solve the problems.
