Ventilation apparatus for general anesthesia

Abstract

The invention belongs to the field of medicines, and particularly discloses a ventilation apparatus for general anesthesia. A tracheal catheter comprises a tracheal inner layer and a tracheal bladder arranged outside the tracheal inner layer. A control unit comprises a rotary sleeve which is in rotary connection with a laryngeal mask catheter, guide slots are formed in the outer side of the rotary sleeve, and the top of the rotary sleeve is connected with a bolt. A sliding cavity and an air supply assembly are arranged in the rotary sleeve; the air supply assembly is used for supplying and feeding air for the tracheal bladder; a slider is in sliding connection in the sliding cavity; a connecting rod penetrates the inside of the slider and is provided with a stop plate; one end of the connecting rod runs through a third communicating port and is connected with the tracheal inner layer; the other end of the connecting rod is connected with an indicating ball which is in sliding connection in the guide slots. A cam mechanism is also arranged in the slider and abutted against the tracheal catheter. According to the technical scheme, hurt to the patient's body caused by rubbing generated in the process of inserting the laryngeal mask catheter and the tracheal catheter can be reduced, insertion of the tracheal catheter is facilitated, the state of the tracheal catheter can be switched conveniently, and thus, work efficiency of medical staff is improved.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a medical appliance. Background technique [0002] When performing general anesthesia surgery, it is necessary to provide assisted breathing for the patient to maintain the hemodynamic stability of the patient under general anesthesia. However, the current endotracheal tube and laryngeal mask breathing device are independent auxiliary breathing devices, and it is very inconvenient to replace each other. , and when switching the breathing mode, it is often easy to cause a series of complications caused by early extubation of the anesthesia and hypersensitivity of the airway. In addition, the old-style laryngeal mask is easy to shift and cause air leakage due to the different positions or changes of the patient's position during the operation, which makes the operation unpredictable and unfavorable. [0003] The authorization number is CN102974014A, which discloses a built-in laryn...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a ventilation device for general anesthesia to solve the problems in the background art that the ventilation device will damage the relevant parts of the patient when inserted, the endotracheal tube is difficult to insert, and the inflation of the laryngeal mask air bag and the endotracheal catheter air bag is inconvenient.
