Annular cartilage pressing device

Abstract

The invention provides an annular cartilage pressing device, relating to a medical appliance. The annular cartilage pressing device provided by the invention can not compress the vessels and nerves of the whole neck, can quantize the pressing force of the annular cartilage and can reflect the pressing conditions in real time, and the pressing force of the annular cartilage pressing device is controllable. The annular cartilage pressing device is provided with a cambered elastic frame and a cambered pressing pad, wherein the cambered pressing pad is connected with one end of the inner side of the cambered elastic frame; a U-shaped elastic frame or a C-shaped elastic frame or the like can be used as the cambered elastic frame; a cambered silica gel pressing pad or a cambered rubber pressingpad or the like can be used as the cambered pressing pad; and the cambered elastic frame is preferably provided with at least one of a pressure sensor, a pressure display, a pressure setting device, a pressure regulator, a release device, a pressure protector, a neck stent and the like.

Description

technical field [0001] The invention relates to a medical device, in particular to a cricoid cartilage depressor mainly used for trachea and esophagus. Background technique [0002] During general anesthesia, in order to prevent substances in the digestive tract from gushing out of the esophagus or gas into the digestive tract, it is often necessary to press the cricoid cartilage to move the cricoid cartilage toward the cervical spine and compress the esophagus with surrounding tissues to block the esophagus. The traditional method is to use fingers to press. Due to the differences in the pressing position, pressing force, pressing time, and operator proficiency, it is often impossible to achieve the purpose of effective pressing.

Problems solved by technology

The traditional method is to use fingers to press. Due to the difference in the pressing position, pressing force, pressing time, and operator proficiency, it is often impossible to achieve the purpose of effective pressing.

[0003] Wu Guanglan, Qian Kejian, Zhao Weilu, Ma Longxian, etc. "Clinical Observation of Cricoid Compressor Preventing General Anesthesia from Quickly Inducing Gas into the Stomach" [J]. Journal of Jiangxi Medical College, 1997, 37(1): 91-92) report The cricoid cartilage compressor uses a special artificial leather half-moon pillow, which is 18cm long, 5cm high, and 8cm wide. The plastic zipper, two zippers are fastened to form a ring, although it plays a role in cricoid cartilage compression, but it has the following disadvantages: 1. The zipper ring fastening method will cause compression to the entire neck blood vessels and nerves, hindering the blood circulation of the brain and Nerve conduction; 2. This fastening fixation method has no pressure display, cannot quantify the strength of the cricoid cartilage pressing, and cannot reflect the pressing situation; 3. This method has no pressure protection device, and it is easy to cause damage to the tracheal cartilage ring or cricoid cartilage due to excessive pressure

Therefore, no promotion and application has been seen so far
