Description

A laryngeal mask with atomization function

Technical Field

The utility model relates to the technical field of laryngeal mask intubation, in particular to a laryngeal mask with an atomization function.

Background Art

The laryngeal mask is suitable for patients who are anesthetized or sedated with drugs, as well as patients who need emergency artificial ventilation support during first aid and resuscitation, in order to achieve upper airway patency. The laryngeal mask is mainly composed of a cuff, a laryngeal mask tube, an indicator balloon, an inflation tube, a machine end connector and an inflation valve. The ventilation mask at the front end of the laryngeal mask is oval in shape, which can wrap around the epiglottis and glottis, forming a sealed ventilation space on the glottis. The patient can breathe spontaneously through the laryngeal mask, and controlled ventilation can also be performed. In related surgeries, it is sometimes necessary to supplement drugs through the laryngeal mask, such as supplementing topical anesthetics to increase the anesthesia time, supplementing therapeutic drugs to treat lung infections, etc. In order to improve the absorption effect of drugs, some laryngeal masks are equipped with nebulizers.

However, most existing laryngeal masks with atomizers have poor atomization effects, and most drugs are sprayed in the form of droplets near the glottis, which is not only inconvenient to control drug administration, but also wastes the drug liquid due to the short spraying time. Therefore, a laryngeal mask with better atomization function is needed to solve the above problems.

Compared with the prior art, the utility model has the following beneficial effects:

The laryngeal mask with atomization function is newly equipped with a liquid medicine atomization delivery tube. Liquid medicine is placed in a medicine chamber of the liquid medicine atomization delivery tube and is transported to the first delivery tube and then to the first conical tube through the liquid medicine tube. The trachea is connected to a positive pressure air source, and the airflow is sent from the trachea to the second conical tube. The high-speed airflow rushes out of the tip of the second conical tube to form a Venturi principle. The high-speed airflow forms a negative pressure around the tip of the second conical tube to entrain the liquid medicine and rush it out of the first conical tube. The first spoiler on the first conical tube will generate a turbulent vortex for the airflow carrying the liquid medicine, and the liquid medicine is further atomized. The sleeve guides the atomized medicine to diffuse outside the cuff. Applicable scenarios: 1. Use of aerosol drugs during short surgeries for patients with lung infections; 2. Sufficient surface anesthesia of the throat before bronchoscopy, especially for children and the elderly. The amount of drugs used is significantly reduced compared to the current device that produces water mist with a syringe, thereby reducing the risk of anesthetic poisoning and reducing the metabolic burden on the liver and kidneys; 3. The use of this type of laryngeal mask during general anesthesia in children can provide sufficient surface anesthesia of the throat with a minimum of drugs, avoiding the occurrence of laryngeal spasm.
