Problems solved by technology

However, these ventilation devices have obvious defects. Although the laryngeal mask can solve ventilation and reduce post-anesthesia complications (mainly because the laryngeal mask is easier to tolerate in the oral cavity than the endotracheal tube in the trachea, there will be no coughing, cardiovascular However, the laryngeal mask is an unstable airway, which is not suitable for long-term surgery, and is prone to aspiration, air leakage, and displacement, and cannot be ventilated during light anesthesia laryngospasm
The front end of the esophagus is crushed on the mucosa at the entrance of the esophagus, causing complications such as sore throat; the endotracheal tube is a stable airway ventilation method, and the anesthesiologist will not worry about related accidents caused by unstable airway during the operation, but the long-term surgical sleeve The pressure injury of the airway mucosa by the sac and the pressure injury of the vocal cord by the endotracheal tube can easily cause unbearable postoperative pain, and it is difficult to tolerate the endotracheal tube when the anesthesia is lightened in the late stage of anesthesia, and it is easy to cause choking and cardiovascular diseases. Complications such as severe reactions

specific Embodiment approach 1

[0010] see figure 1 , the specific embodiment adopts the following technical scheme: it comprises an endotracheal tube 1, a catheter cuff 2, a tube changer insertion hole 3, a movable overtube 4, and a laryngeal mask bag 5, and the front end of the endotracheal tube 1 is provided with Catheter cuff 2, the rear end of the front end of the endotracheal tube 1 is provided with a tube changer insertion hole 3, the outer side of the endotracheal tube 1 is sleeved with a movable outer tube 4, and the front end of the movable outer tube 4 is provided with Throat mask bag5.

[0011] The working principle of the present invention: after general anesthesia, the anesthesiologist inserts the front end of the multifunctional ventilation tube into the blocking cuff in the trachea to form a stable airway ventilation, and when the operation time is long, the endotracheal tube can be cuffed Deflation. Inflate the laryngeal mask bag to block the pharyngeal cavity, and continue general anesthe...

specific Embodiment approach 2

[0013] see figure 2 The difference between this embodiment and Embodiment 1 is that the movable overtube 4 is removed, and the laryngeal mask bag 5 is arranged at the rear end of the catheter cuff 2 of the endotracheal tube 1, and other connections are the same as in Embodiment 1. same. .

specific Embodiment approach 3

[0014] see image 3 The difference between this specific embodiment and the first specific embodiment is that the removable overtube 4 is replaced by a flexible support 6, and the laryngeal mask bag 5 is separated from the surface of the endotracheal tube 1 to become an independent individual. , and other connections are the same as those in the first embodiment.

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a multifunctional breather tube for general anesthesia surgery. A catheter sleeving balloon (2) is arranged at the front end of a tracheal catheter (1), the rear end of the tracheal catheter (1) is provided with a tube exchanger insertion hole (3), an outer sleeving tube (4) which is movable externally sleeves the tracheal catheter (1), and a gular covering balloon (5) is arranged at the front end of the movable outer sleeving tube (4). Free breath switching between the tracheal catheter and a gular cover is realized to further realize free switching between intratracheal breath and larynx or pharynx breath, and consequently subsequent complication resulted from the general anesthesia surgery can be avoided.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional ventilation tube for general anesthesia. Background technique: [0002] Clinically, in order to control the breathing of patients under general anesthesia, it is mainly realized through a tracheal supervisor and a laryngeal mask. However, these ventilation devices have obvious defects. Although the laryngeal mask can solve ventilation and reduce post-anesthesia complications (mainly because the laryngeal mask is easier to tolerate in the oral cavity than the endotracheal tube in the trachea, there will be no coughing, cardiovascular However, the laryngeal mask is an unstable airway, which is not suitable for long-term surgery, and is prone to aspiration, air leakage, and displacement, and cannot be ventilated during light anesthesia laryngospasm. The front end of the esophagus is crushed on the mucosa at the entrance of the esophagus, causing complicat...
