Embodiment Construction

[0013] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0014] Please refer to Fig. 1 and Fig. 2, the disposable silicone plastic laryngeal mask comprises a ventilation catheter 4 made of non-toxic plastic PVC and an inflatable mask 1 made of oval silicone material connected to the ventilation catheter. The inflatable mask 1 It is composed of a hollow cylindrical airbag and an airbag seat at an angle with a vent hole on it. The outer edge of the inflatable cover 1 is connected with an inflatable tube 6 made of non-toxic plastic PVC material, in order to enhance the strength of the ventilation tube wall so that The medical personnel safely and quickly insert the laryngeal mask into the patient's throat, and maintain the lumen of the laryngeal mask ventilation catheter in an unobstructed state. A sta...

Abstract

The invention relates to a one-time silicon plastic throat mask, which comprises a ventilate tube, and an aerate mask connected to the tube. Wherein, the mask is formed by connected hollow cylinder air bubble and air bubble base; the air bubble is connected to aerate tube at the edge; the wall of tube is embedded with strengthen liner; the mask can be silicon rubber; the aerate tube is made from non-toxic medical PVC; the aerate tube via the connector with annular cam and annular groove is connected to the mask. The invention has the advantages that: via the match between two connectors and aerate mask, and the connection between connectors and aerate tube, the silicon rubber tube and the plastic tube can be connected firmly. The invention has low cost, while it can avoid repeated application which will cause hypoderm.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a disposable silicon-plastic laryngeal mask with low cost, easy operation and tight and reliable sealing, which is used in surgical anesthesia or rescue of critically ill patients. Background technique [0002] At present, in clinical rescue of patients with cardiac and respiratory arrest and patients who need to receive general anesthesia, laryngeal masks are often used to replace endotracheal intubation or breathing masks and other equipment in order to maintain their breathing and establish effective artificial airways. At present, laryngeal mask products are mostly made of silicone rubber. The airbag is flexible and has good adhesion, which is conducive to forming a seal in the patient's throat. However, due to the high cost, it is not conducive to the popularization of laryngeal masks in my country, and it is prone to clinical Risk of cross-infection. In recent years...
