A multi-channel oropharyngeal ventilation device for anesthesia department

Abstract

The invention discloses a multi-passage oropharyngeal ventilation apparatus for anesthesia department. The ventilation apparatus comprises a panel, wherein a male fastener is arranged at the end of a binding band on one side and a female fastener is arranged at the end of a binding band on the other side; a gas flow sensor is arranged at one end of a connector, and an auxiliary port is formed in the outer side of the connector; the other side of the gas flow sensor is connected to a filter device; a groove is formed in the middle of the filter device; an activated carbon storage device is arranged in the groove, and a handle is arranged at the upper part of the activated carbon storage device; the middle of the inner side of a fixed plate is connected to one end of a gas-guide tube; a locating tube is arranged on the fixed plate on the periphery of the gas-guide tube, and locating holes are formed in four corners of the fixed plate; the gas flow sensor is electrically connected to a controller; the controller is electrically connected to a display screen; and the controller is connected to an external power supply by virtue of a lead wire. The apparatus is convenient to replace the gas-guide tube and is capable of avoiding cross infection of a patient; and the apparatus is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-channel oropharyngeal ventilator for anesthesiology. Background technique [0002] At present, the anesthesiology department performs anesthesia operations on patients or some shock patients need to first open the passage of the oral cavity to ensure the normal breathing of the patient, and if necessary, oxygen inhalation and other operations need to be performed through this passage. However, the general oropharyngeal ventilation device can only form a smooth ventilation channel for the oropharynx, and it is very difficult to perform operations such as gastric tube insertion and sputum suction, and the air directly introduced has more impurities, which will affect the patient. In addition, it is impossible to determine whether the patient's breathing is unobstructed. Therefore, we propose a multi-channel oropharyngeal ventilation device for anesthesia. Contents...
