A convertible built-in endotracheal tube and laryngeal mask combined ventilation device

Abstract

The invention discloses a switchable built-in tracheal catheter and laryngeal mask combined breathing device. The device comprises a laryngeal mask, a tracheal catheter, and a sealing locking device arranged on the device; the front end of the tracheal catheter is inserted into a laryngeal mask catheter from the far end of the laryngeal mask catheter; the rear end of the tracheal catheter can be pushed to enable the tracheal catheter to freely slide into the laryngeal mask catheter. According to the device, the tracheal catheter and the laryngeal mask can be switched in different breathing modes; the built-in tracheal catheter breathing mode is used in patient operations such as operation for different body part, or fat patients, high blood pressure patients and diabetes patients so as to improve the reliability and safety of assistant breathing; the laryngeal mask breathing mode is switched when the patient wakes from general anesthesia, so that the probability of airway hypersensitive reaction such as bucking caused by the tracheal catheter breathing mode can be reduced; the complication caused by bucking in the waking period can be reduced by the mode of replacing drugs.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a combined ventilation device of a convertible built-in tracheal tube and a laryngeal mask. Background technique [0002] Assisted breathing ventilation is a necessary means to assist patients with breathing during general anesthesia operations to maintain the hemodynamic stability of patients under general anesthesia. Devices such as endotracheal tubes and laryngeal masks are commonly used assisted breathing devices for assisted breathing and ventilation. In clinical practice, auxiliary breathing devices such as endotracheal tube and laryngeal mask are mostly used independently, but it is often necessary to switch between different ventilation methods to achieve different effects during surgery. It is very inconvenient to replace, and it is often easy to extubate early in the anesthesia when switching the breathing mode, resulting in hypersensitivity of the airway, leading to a series of c...

In clinical practice, auxiliary breathing devices such as endotracheal tube and laryngeal mask are mostly used independently, but it is often necessary to switch between different ventilation methods to achieve different effects during the operation. It is very inconvenient to replace, and when the breathing mode is switched, it is often easy to cause early extubation due to anesthesia, resulting in hypersensitivity of the airway, leading to a series of complications and increasing the risk of surgery
