Problems solved by technology

The current tracheal tube and laryngeal mask breathing device are independent auxiliary breathing devices, which are very inconvenient to replace each other, and it is often easy to cause hypersensitivity reactions in the airway due to early extubation during anesthesia when switching breathing modes. series of complications
In addition, the old-style laryngeal mask is easy to shift and cause air leakage due to the different positions or changes in the patient's position during the operation.

Abstract

The invention discloses a built-in laryngeal mask catheter and laryngeal mask combined ventilation device for general anesthesia. The combined ventilation device comprises a laryngeal mask catheter, atelescopic device and a laryngeal mask, wherein the telescopic device is arranged inside the laryngeal mask catheter and is used for adjusting the length of a pipeline; the laryngeal mask is arrangedat one end of the laryngeal mask catheter and is used for sealing a throat; a semicircular boss is arranged on the upper surface of the laryngeal mask; a joint is arranged at one end of the telescopic device; and an inflation and deflation device is connected to the laryngeal mask and the telescopic device. According to the invention, a tracheal catheter and the laryngeal mask catheter are overlapped, so that repeated intubation operation is avoided; and meanwhile, the laryngeal mask at one end of the laryngeal mask catheter and a tracheal sealing capsule on the tracheal catheter are used fordouble sealing, so that sealing performance is improved, air leakage is avoided, and safe operation is ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a built-in laryngeal mask catheter laryngeal mask combined ventilation device for general anesthesia. Background technique [0002] When performing general anesthesia operations, it is necessary to provide assisted breathing to the surgical patient to maintain the hemodynamic stability of the patient under general anesthesia. The tracheal tube ventilation device is composed of a tracheal tube composed of a long and thin tube. An inflatable balloon. During the procedure, the distal end of the tracheal tube is inserted into the patient's mouth and through the patient's laryngeal entrance into the patient's trachea. The tracheal tube, once so positioned, inflates the balloon to form a seal against the inner passage of the trachea. After the seal is formed, positive pressure is applied to the proximal end of the tracheal tube to inflate the patient's lungs. The advantage of the endo...
