A Y-shaped laryngeal mask with an instrument channel

Abstract

The invention discloses a Y-shaped laryngeal mask with an instrument channel, which belongs to the technical field of medical instruments. It includes a ventilation catheter, a ventilation cover, and an air injection cuff, and the gas injection cuff is connected with an air injection tube; the ventilation catheter is a Y-shaped tube, and the front end of the ventilation catheter is connected with a main pipe directly connected with the ventilation catheter and a connection with the ventilation catheter at an inclined angle. Auxiliary pipe; the end of the main pipe is sealed, and there is a cross-shaped cut at the sealing place of the main pipe end; the end of the main pipe has a sealing cap; the connection port between the ventilation cover and the ventilation duct is circular, and there is a flexible pipe in the connection port. The circular ring is connected to the connecting port by flexible bands around the circular ring. When the bronchofiberscope passes through the cross-shaped incision at the end of the main pipe, the cross-shaped incision is opened and closely attached to the tube wall of the bronchofiberscope to ensure airtightness. The bronchofiberscope passes through the flexible ring in the connection port, and The flexible band of the ventilator prevents the lumen from being blocked by the epiglottis.

Description

technical field [0001] The invention relates to a medical device, in particular to an airway management device used for general anesthesia during clinical bronchoscopic diagnosis and treatment. Background technique [0002] At this stage, with the rapid development of medical science and technology, new diagnosis and treatment technologies are constantly being introduced, and bronchoscopy has been widely used in the diagnosis, identification and treatment of respiratory diseases. With the development of respiratory interventional therapy technology, interventional therapy technologies such as argon plasma coagulation, freezing, electrocautery, stent implantation, and balloon dilation under fiberoptic bronchoscope have replaced surgery and become an important means of treating airway diseases. Microscopic examination is an invasive operation that often causes severe coughing, nausea and vomiting, restlessness, and brings tension, anxiety, and pain to patients, thereby affecti...

Problems solved by technology

However, the trachea examination and anesthesia breathing management share the same channel, which is often restricted during the operation, which increases the difficulty of the operation and leads to related complications
