Description

Endotracheal tube complete built-in laryngeal mask combined ventilation device

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to medical devices, and more particularly to a tracheal catheter fully built-in laryngeal mask combined venting device. Background technique

In the case of general anesthesia, assisted breathing is required to maintain the patient's general hemodynamic stability. Commonly used assisted breathing devices include endotracheal tube ventilation and laryngeal breathing device.

The endotracheal tube ventilation device consists of a tracheal tube formed of an elongated tube with an inflatable balloon disposed at the distal end of the elongated tube. During operation, the distal end of the tracheal tube is inserted into the patient's mouth and into the patient's trachea through the patient's throat inlet (or glottal opening). Once the tracheal tube is positioned as such, the balloon is inflated to form a seal against the internal passage of the trachea. After the seal is formed, a positive pressure is applied to the proximal end of the tubing to inflate the patient's lungs. The advantage of an endotracheal tube is that it can withstand large sealing pressures and is less prone to air leaks. The main drawback is that it is difficult to properly insert the pipe, which is too technically demanding for the actual operator. In addition to this major drawback, there are other deficiencies associated with the tracheal tube. For example, tracheal tubing often causes severe "throat pain" in the patient. This "throat pain" is mainly caused by the friction between the tube and the recess between the patient's cartilage tissue, and can also cause a severe cough response in the patient.

In contrast to the tracheal tube, the laryngeal mask ventilator can be easily inserted into the patient to create a breathing passage. In addition, the laryngeal mask venting device is an "acceptable" device because the laryngeal mask venting device establishes a breathing passage even if it is incorrectly inserted. Therefore, laryngeal mask ventilation is often considered a "life-saving" device. Alternatively, the laryngeal mask ventilation device can be inserted only by performing a small escapement of the patient's head, neck and mouth. In addition, the laryngeal mask ventilation device can inflate the patient's lungs without contacting the inner passage of the trachea sensitive portion, and the size of the respiratory passage established by the laryngeal mask ventilation device is significantly larger than that of the tracheal tube. The size of the vertical breathing channel. The main drawback of the laryngeal mask ventilation device is that the cost is high, and the sealing pressure is too small to cause air leakage, the patient's position is high, and it is easy to shift to other special position patients to cause control ventilation failure.

Current tracheal tube ventilation devices and laryngeal mask ventilation devices are usually independent auxiliary breathing devices, which are very inconvenient to replace each other, and often cause a high-sensitivity reaction in the airway due to early extubation of the anesthesia when switching the breathing mode. The resulting series of complications have unpredictable disadvantages in surgery.
