Problems solved by technology

Although the esophageal drainage type laryngeal mask airway has a certain preventive effect on gastric aspiration, but in patients with high risk of pulmonary aspiration (such as patients with a full stomach), this improved laryngeal mask airway still cannot achieve satisfactory results. respiratory protection

Embodiment Construction

[0036] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0037] Such as image 3 , Figure 4 with Figure 5 As shown, it is an embodiment of an esophageal obstruction type laryngeal mask airway, comprising:

[0038] A ventilation catheter 1 is made of silicone rubber, and the tube wall is prefabricated with a helical wire to enhance the strength of the tube wall and maintain the lumen in a smooth state. The proximal end of the ventilation catheter 1 has a standard ventilation loop connector 11. The joint 11 is detachably connected to the ventilation conduit 1;

[0039] A ventilation cover 2 is similar to an elliptical oblique cone, made of soft and thin rubber, and the bottom periphery of the oblique cone is a hollow cylindrical elliptical ring bulge 21, and its oblique cone surface 22 is made of soft rubber sheet, and the oblique cone surface 22 It is glued tightly co...

Abstract

The present invention relates to an esophagus-blocking type larynx cover ventilation channel. It includes an airway, a ventilation cover, a drainage-tube, a stabilizing device, also includes a fine tube cavity placed on inner side of tube wall of drainage-tube, an esophagus-blocking device, also further includes a fine cavity cathether, its front end side-wall has an air-charging hole, its rear end has an air-charging valve, the fine cavity catheter is passed through the fine tube cavity in drainage-tube wall and can be moved up-down along the fine tube cavity, a cover bag, a marker and a limiting device. Said invention also provides its application method.

Description

technical field [0001] The invention relates to a medical instrument used in surgical anesthesia and rescue of critically ill patients-a laryngeal mask airway, in particular to an esophageal obstruction type laryngeal mask airway. Background technique [0002] The laryngeal mask airway is a new type of airway invented by Brain in 1983 and first advocated for use. Its basic structure is as figure 1 As shown, there is a ventilation catheter 1 and a ventilation mask 2. The purpose of the design is: after insertion, the ventilation mask 2 at the distal end is located in the hypopharynx a, and forms a seal around the larynx b, and the wall of the long axis of the ventilation mask 2 faces the pear shaped crypts. The hypopharynx a or hypopharynx b is the pharyngeal space behind the arytenoid and cricoid cartilages. Therefore, when the airway of the laryngeal mask is inserted correctly, the distal end of the ventilation mask 2 is located behind the arytenoid cartilage and cricoid...
