Abstract

The invention provides an auxiliary sound production valve which comprises a rotary outer shell, an inner core, a clack membrane, a protecting cap and moisturizing filtering cotton. The auxiliary sound production valve is exquisite in structural design and convenient and rapid to install and has a switching function, the switching between speaking and respiration can be realized for a patient by rotating a button, the inconvenient and ungraceful situation that the patient can not speak until blocking one end by hand is avoided, the auxiliary sound production valve is used in cooperation with a tracheostomy tube, the switching between respiration and speaking is realized for the patient by rotating, the auxiliary sound production valve does not need to be pulled out after installation, the use performance of the product is remarkably improved, it is guaranteed that the air inhaled by the patient is wet and pure, and the comfort level is increased.

Description

technical field [0001] The invention relates to a medical device, in particular to an auxiliary sounding valve. Background technique [0002] Tracheostomy intubation is a common medical device for respiratory anesthesia. It is widely used in clinical use to rescue critically ill patients, establish a respiratory management system, and keep the patient's airway unobstructed. Its simple operation method and remarkable use effect have been widely used in clinical practice. Good reviews from doctors and patients. For patients requiring tracheostomy intubation, the laryngeal tracheotomy is required, and the tracheal tube is then inserted. For patients with self-consciousness, when they need to speak, one end of the intubation tube is blocked, so that the gas can be generated through the vocal cords; if it is not blocked, they cannot speak. Because the above-mentioned products occurring on the market are only simple speaking valve devices, they can be installed if they need to s...
