Description

A laryngeal mask that can be used for gastroscopy

technical field

The utility model relates to the field of medical equipment, in particular to a laryngeal mask which can be used for gastroscopy.

Background technique

The laryngeal mask is an effective means to establish a safe airway in general anesthesia. The first and second generation laryngeal masks have many advantages: first, they are easy to use and can quickly establish an artificial airway; second, they have a high success rate of placement, The success rate of untrained medical staff is 87%, and the total success rate is 99.81%; third, reliable ventilation; fourth, avoid throat and tracheal mucosa damage; fifth, less stimulation and less cardiovascular response; sixth, available It is suitable for first aid, but the traditional first- and second-generation laryngeal masks are not completely sealed with the respiratory tract, and oral secretions increase and are easy to shift. Its application in clinical anesthesia.

The third-generation laryngeal mask was designed by the inventor Brain in 2000 and used clinically; in recent years, with the advancement of materials and technology, a variety of improved third-generation laryngeal masks have appeared. In order to improve the clinical performance of the laryngeal mask Application effect, there are currently three types of third-generation laryngeal masks: the first is the standard laryngeal mask, which is also the most commonly used laryngeal mask in clinical practice. It is mainly used to maintain the function of the respiratory tract, and drainage operations cannot be performed; the second type is a special laryngeal mask for guiding tracheal intubation; the third type is a drainage type laryngeal mask, which is not only used to maintain the function of the respiratory tract, but also used to treat esophageal reflux substances. For drainage, the structure is similar to a common laryngeal mask, except that a drainage tube parallel to the ventilation tube is added. The existing laryngeal mask has a single function and cannot satisfy airway control during painless gastroscopy.

Utility model content

The purpose of this utility model is to provide a laryngeal mask that can be used for gastroscopic examination, so as to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A laryngeal mask that can be used for gastroscopic examination, including a cover, an air tube, a catheter and a gastroscope placement tube, the inner cavity of the cover is connected with an inflatable tube, and an indicating air bag and a one-way valve are arranged on the inflatable tube. Connected with one end of the catheter, the catheter communicates with the opening of the hood, the catheter acts as a breathing channel, and the hood is provided with a penetrating gastroscope placement tube, which is used to place the gastroscope.

As a further solution of the utility model: the end of the inflation tube is provided with an inflation port.

As a further solution of the utility model: the other end of the catheter is provided with an anesthesia ventilator interface, and the anesthesia ventilator interface is used to connect to the anesthesia ventilator.

As a further solution of the utility model: the cover is made of polyvinyl chloride.

Compared with the prior art, the beneficial effect of the utility model is: the utility model is provided with a one-way valve and an indicating airbag at the inflation end of the inflation tube, so the gas in the cuff can be released quickly after the operation, and the deflation process Among them, it is more intuitive to judge the remaining gas volume in the cuff by indicating the air bag. At the same time, a gastroscope placement tube is added to perform gastroscopy, and a painless gastroscopy channel is established for artificial respiration. Ventilation, thereby ensuring the patency of the upper airway of the patient, and avoiding the occurrence of hypoxemia.
